tft display vs super amoled display hindi factory

Thanks for the display technology development, we have a lot of display choices for our smartphones, media players, TVs, laptops, tablets, digital cameras, and other such gadgets. The most display technologies we hear are LCD, TFT, OLED, LED, QLED, QNED, MicroLED, Mini LED etc. The following, we will focus on two of the most popular display technologies in the market: TFT Displays and Super AMOLED Displays.

TFT means Thin-Film Transistor. TFT is the variant of Liquid Crystal Displays (LCDs). There are several types of TFT displays: TN (Twisted Nematic) based TFT display, IPS (In-Plane Switching) displays. As the former can’t compete with Super AMOLED in display quality, we will mainly focus on using IPS TFT displays.

OLED means Organic Light-Emitting Diode. There are also several types of OLED, PMOLED (Passive Matrix Organic Light-Emitting Diode) and AMOLED (Active Matrix Organic Light-Emitting Diode). It is the same reason that PMOLED can’t compete with IPS TFT displays. We pick the best in OLED displays: Super AMOLED to compete with the LCD best: IPS TFT Display.

AMOLED and TFT are two types of display technology used in smartphones. AMOLED (active-matrix organic light-emitting diode) displays are made up of tiny organic light-emitting diodes, while TFT (Thin-Film Transistor) displays use inorganic thin-film transistors.

AMOLEDs are made from organic materials that emit light when an electric current is passed through them, while TFTs use a matrix of tiny transistors to control the flow of electricity to the display.

Refresh Rate: Another key difference between AMOLED and TFT displays is the refresh rate. The refresh rate is how often the image on the screen is updated. AMOLED screens have a higher refresh rate than TFT screens, which means that they can display images more quickly and smoothly.

Response Time: The response time is how long it takes for the pixels to change from one colour to another. AMOLED screens have a shorter response time than TFT screens..

Colour Accuracy/Display Quality: AMOLED screens are more accurate when it comes to displaying colours. This is because each pixel on an AMOLED screen emits its own light, which means that the colours are more pure and true to life. TFT screens, on the other hand, use a backlight to illuminate the pixels, which can cause the colours to appear washed out or less vibrant.

Viewing Angle: The viewing angle is the angle at which you can see the screen. AMOLED screens have a wider viewing angle than TFT screens, which means that you can see the screen from more angles without the colours looking distorted.

Power Consumption: One of the main advantages of AMOLED displays is that they consume less power than TFT displays. This is because the pixels on an AMOLED screen only light up when they need to, while the pixels on a TFT screen are always illuminated by the backlight.

Production Cost: AMOLED screens are more expensive to produce than TFT screens. This is because the manufacturing process for AMOLED screens is more complex, and the materials used are more expensive.

Availability: TFT screens are more widely available than AMOLED screens and have been around for longer. They are typically used in a variety of devices, ranging from phones to TVs.

Usage: AMOLED screens are typically used in devices where power consumption is a concern, such as phones and wearable devices. TFT screens are more commonly used in devices where image quality is a higher priority, such as TVs and monitors.

AMOLED and TFT are two different types of display technology. AMOLED displays are typically brighter and more vibrant, but they are more expensive to produce. TFT displays are cheaper to produce, but they are not as bright or power efficient as AMOLED displays.

The display technology that is best for you will depend on your needs and preferences. If you need a screen that is bright and vibrant, then an AMOLED display is a good choice. If you need a screen that is cheaper to produce, then a TFT display is a good choice. However, if you’re worried about image retention, then TFT may be a better option.

It can be argued that the display on your smartphone is its most important feature, as it is the principle way in which you interact with your device. A poor display means a poor user experience. As with all tech, it is easy to spot an under-performer, however the differences between a good display and a truly excellent display are harder to discern.

Roughly speaking there are two main types of displays used in smartphones: LCD and LED. These two base technologies have been refined and tweaked to give us AMOLED and IPS LCD. The former stands for Active Matrix Organic Light-Emitting Diode, while the latter means In-Plane Switching Liquid Crystal Display.

All of this hasn’t gone unnoticed by the marketing people, which means that plain old AMOLED or regular IPS LCD aren’t the terms used in the marketing fluff. Instead, we have Super AMOLED, Dynamic AMOLED, Super LCD, Super Retina OLED, Super Retina XDR, Infinity Display, and so on. But what’s any of that actually mean?

The LED part of AMOLED stands for Light Emitting Diode. It’s the same tech as you find on many home appliances that show that the power is on with a little red light. An LED display takes this concept, shrinks it down, and arranges the LEDs in red, green, and blue clusters to create an individual pixel.

The O in AMOLED stands for organic. It refers to a series of thin organic material films placed between two conductors in each LED. These produce light when a current is applied.

Finally, the AM part in AMOLED stands for Active Matrix, rather than a passive matrix technology. In a passive matrix, a complex grid system is used to control individual pixels, where integrated circuits control a charge sent down each column or row. But this is rather slow and can be imprecise. Active Matrix systems attach a thin film transistor (TFT) and capacitor to each sub-pixel (i.e. red, green, or blue) LED. The upshot is that when a row and column is activated, the capacitor at the pixel can retain its charge in between refresh cycles, allowing for faster and more precise control.

The image above is a close-up shot of the AMOLED display on the Samsung Galaxy S8. The RGB triangular pattern is clearly shown. Towards the bottom of the image, the green and red LEDs are off and the blue LEDs are on only slightly. This is why AMOLED displays have deep blacks and good contrast.

Super AMOLED is a marketing term from Samsung. It means a display that incorporates the capacitive touchscreen right in the display, instead of it being a separate layer on top of the display. This makes the display thinner.

Dynamic AMOLED is another marketing term from Samsung. It denotes Samsung’s next-generation AMOLED display which includes HDR10+ certification. According to Samsung, Dynamic AMOLED also reduces the harmful blue light emitted from the display, which helps reduce eye strain and helps lessen sleep disturbances if you’re using your phone late in the day!

As for Infinity Display (or Infinity-O Display), it is more marketing from Samsung. It means “a near bezel-less, full-frontal, edge-to-edge” display. However, it is still a Super AMOLED unit.

LCD displays work with a backlight that shines through some polarizing filters, a crystal matrix, and some color filters. Liquid crystals untwist when an electric charge is applied to them, which affects the frequency of the light that can pass through. Since the crystals can be twisted to varying degrees depending on the voltage used, a display can be built when they are used with polarized panels. A grid of integrated circuits is then used to control each pixel, by sending a charge down into a specific row or column. Colors are created by the use of red, green, and blue filters, known as sub-pixels, which are then blended by varying degrees to produce different colors.

The above image is of an LCD display from a Huawei Mate 8. Notice how the pixels are made up of equally-sized sub-pixels, one for each of the colors: red, green, and blue.

Like Super AMOLED, a Super LCD display also incorporates the touchscreen. There is no “air gap” between the outer glass and the display element, which means it has similar benefits to Super AMOLED.

Samsung isn’t the only company that is good at marketing, there is another! Apple has coined the term “Retina” for its displays. The term was first used for its smartphones with the launch of the iPhone 4, as it offered a significantly greater pixel density (over 300 ppi) when compared to the iPhone 3GS. Later came Retina HD, which applies to iPhones with at least a 720p screen resolution.

All Retina and Retina HD displays on the iPhone are LCD IPS displays. However, things have changed a bit with the iPhone X as it features an AMOLED display, now marketed under the term Super Retina. It’s still an AMOLED display. It just has extra adjectives. With the launch of the iPhone 11 Pro, Apple coined the term Super Retina XDR. The XDR part means Extended Dynamic Range, as they have better contrast ratios and higher peak brightness.

Not all Retina displays use OLED. Although the MacBook Pro is marketed with a “Retina” display, as you can see from the magnified image above, it is a regular LCD, even if it uses the latest Apple silicon.

Both technologies can be used to build displays with 720p, 1080p, Quad HD, and 4K resolutions. And OEMs have made handsets that support HDR10 using both LCD and AMOLED displays. So from that point of view, there isn’t much difference between the two.

When it comes to color, we know that the blacks will be deeper and the contrast ratios higher on AMOLED displays. But, overall color accuracy can be high on both types of display.

One of the main weaknesses of AMOLED displays is the possibility of “burn-in”. This is the name given to a problem where a display suffers from permanent discoloration across parts of the panel. This may take the form of a text or image outline, fading of colors, or other noticeable patches or patterns on the display. The display still works as normal, but there’s a noticeable ghost image or discoloration that persists. It occurs as a result of the different life spans between the red, green, and blue LED sub-pixels used in OLED panels.

Blue LEDs have significantly lower luminous efficiency than red or green pixels, which means that they need to be driven at a higher current. Higher currents cause the pixels to degrade faster. Therefore, an OLED display’s color doesn’t degrade evenly, so it will eventually lean towards a red/green tint (unless the blue sub-pixel is made larger, as you can see in the first image in this post). If one part of the panel spends a lot of time displaying a blue or white image, the blue pixels in this area will degrade faster than in other areas.

The theoretical lifespan of an AMOLED display is several years, even when used for 12 hours a day. However, there is anecdotal evidence that some displays suffer from burn-in quicker than others. Displays that show signs of burn-in after only a few months should be considered defective because they certainly aren’t normal.

Picking a winner can be hard as there are many factors to consider, not only about the display technologies but also about the other components in a handset. For example, if you are an AMOLED fan, then would you consider a device with large storage and a good processor, but with an LCD display? The same argument works the other way for LCD fans. Generally, you’ll be fine with either display type, so just pick the handset you like.

Higher-end devices typically sport AMOLED displays and mid-range/budget devices usually use LCD. But that isn’t set in concrete as there are plenty of high-end devices that have LCD displays. With OLED production costs dropping dramatically in recent years, more and more budget options will be offering OLED panels in the future.

What do you think? AMOLED or LCD? What about the terms like Retina vs Infinity Display? Are they meaningful to you? Please let me know in the comments below.

A thin-film-transistor liquid-crystal display (TFT LCD) is a variant of a liquid-crystal display that uses thin-film-transistor technologyactive matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven (i.e. with segments directly connected to electronics outside the LCD) LCDs with a few segments.

In February 1957, John Wallmark of RCA filed a patent for a thin film MOSFET. Paul K. Weimer, also of RCA implemented Wallmark"s ideas and developed the thin-film transistor (TFT) in 1962, a type of MOSFET distinct from the standard bulk MOSFET. It was made with thin films of cadmium selenide and cadmium sulfide. The idea of a TFT-based liquid-crystal display (LCD) was conceived by Bernard Lechner of RCA Laboratories in 1968. In 1971, Lechner, F. J. Marlowe, E. O. Nester and J. Tults demonstrated a 2-by-18 matrix display driven by a hybrid circuit using the dynamic scattering mode of LCDs.T. Peter Brody, J. A. Asars and G. D. Dixon at Westinghouse Research Laboratories developed a CdSe (cadmium selenide) TFT, which they used to demonstrate the first CdSe thin-film-transistor liquid-crystal display (TFT LCD).active-matrix liquid-crystal display (AM LCD) using CdSe TFTs in 1974, and then Brody coined the term "active matrix" in 1975.high-resolution and high-quality electronic visual display devices use TFT-based active matrix displays.

The liquid crystal displays used in calculators and other devices with similarly simple displays have direct-driven image elements, and therefore a voltage can be easily applied across just one segment of these types of displays without interfering with the other segments. This would be impractical for a large display, because it would have a large number of (color) picture elements (pixels), and thus it would require millions of connections, both top and bottom for each one of the three colors (red, green and blue) of every pixel. To avoid this issue, the pixels are addressed in rows and columns, reducing the connection count from millions down to thousands. The column and row wires attach to transistor switches, one for each pixel. The one-way current passing characteristic of the transistor prevents the charge that is being applied to each pixel from being drained between refreshes to a display"s image. Each pixel is a small capacitor with a layer of insulating liquid crystal sandwiched between transparent conductive ITO layers.

The circuit layout process of a TFT-LCD is very similar to that of semiconductor products. However, rather than fabricating the transistors from silicon, that is formed into a crystalline silicon wafer, they are made from a thin film of amorphous silicon that is deposited on a glass panel. The silicon layer for TFT-LCDs is typically deposited using the PECVD process.

Polycrystalline silicon is sometimes used in displays requiring higher TFT performance. Examples include small high-resolution displays such as those found in projectors or viewfinders. Amorphous silicon-based TFTs are by far the most common, due to their lower production cost, whereas polycrystalline silicon TFTs are more costly and much more difficult to produce.

The twisted nematic display is one of the oldest and frequently cheapest kind of LCD display technologies available. TN displays benefit from fast pixel response times and less smearing than other LCD display technology, but suffer from poor color reproduction and limited viewing angles, especially in the vertical direction. Colors will shift, potentially to the point of completely inverting, when viewed at an angle that is not perpendicular to the display. Modern, high end consumer products have developed methods to overcome the technology"s shortcomings, such as RTC (Response Time Compensation / Overdrive) technologies. Modern TN displays can look significantly better than older TN displays from decades earlier, but overall TN has inferior viewing angles and poor color in comparison to other technology.

Most TN panels can represent colors using only six bits per RGB channel, or 18 bit in total, and are unable to display the 16.7 million color shades (24-bit truecolor) that are available using 24-bit color. Instead, these panels display interpolated 24-bit color using a dithering method that combines adjacent pixels to simulate the desired shade. They can also use a form of temporal dithering called Frame Rate Control (FRC), which cycles between different shades with each new frame to simulate an intermediate shade. Such 18 bit panels with dithering are sometimes advertised as having "16.2 million colors". These color simulation methods are noticeable to many people and highly bothersome to some.gamut (often referred to as a percentage of the NTSC 1953 color gamut) are also due to backlighting technology. It is not uncommon for older displays to range from 10% to 26% of the NTSC color gamut, whereas other kind of displays, utilizing more complicated CCFL or LED phosphor formulations or RGB LED backlights, may extend past 100% of the NTSC color gamut, a difference quite perceivable by the human eye.

IPS has since been superseded by S-IPS (Super-IPS, Hitachi Ltd. in 1998), which has all the benefits of IPS technology with the addition of improved pixel refresh timing.

In 2004, Hydis Technologies Co., Ltd licensed its AFFS patent to Japan"s Hitachi Displays. Hitachi is using AFFS to manufacture high end panels in their product line. In 2006, Hydis also licensed its AFFS to Sanyo Epson Imaging Devices Corporation.

Less expensive PVA panels often use dithering and FRC, whereas super-PVA (S-PVA) panels all use at least 8 bits per color component and do not use color simulation methods.BRAVIA LCD TVs offer 10-bit and xvYCC color support, for example, the Bravia X4500 series. S-PVA also offers fast response times using modern RTC technologies.

A technology developed by Samsung is Super PLS, which bears similarities to IPS panels, has wider viewing angles, better image quality, increased brightness, and lower production costs. PLS technology debuted in the PC display market with the release of the Samsung S27A850 and S24A850 monitors in September 2011.

TFT dual-transistor pixel or cell technology is a reflective-display technology for use in very-low-power-consumption applications such as electronic shelf labels (ESL), digital watches, or metering. DTP involves adding a secondary transistor gate in the single TFT cell to maintain the display of a pixel during a period of 1s without loss of image or without degrading the TFT transistors over time. By slowing the refresh rate of the standard frequency from 60 Hz to 1 Hz, DTP claims to increase the power efficiency by multiple orders of magnitude.

Due to the very high cost of building TFT factories, there are few major OEM panel vendors for large display panels. The glass panel suppliers are as follows:

External consumer display devices like a TFT LCD feature one or more analog VGA, DVI, HDMI, or DisplayPort interface, with many featuring a selection of these interfaces. Inside external display devices there is a controller board that will convert the video signal using color mapping and image scaling usually employing the discrete cosine transform (DCT) in order to convert any video source like CVBS, VGA, DVI, HDMI, etc. into digital RGB at the native resolution of the display panel. In a laptop the graphics chip will directly produce a signal suitable for connection to the built-in TFT display. A control mechanism for the backlight is usually included on the same controller board.

The low level interface of STN, DSTN, or TFT display panels use either single ended TTL 5 V signal for older displays or TTL 3.3 V for slightly newer displays that transmits the pixel clock, horizontal sync, vertical sync, digital red, digital green, digital blue in parallel. Some models (for example the AT070TN92) also feature input/display enable, horizontal scan direction and vertical scan direction signals.

New and large (>15") TFT displays often use LVDS signaling that transmits the same contents as the parallel interface (Hsync, Vsync, RGB) but will put control and RGB bits into a number of serial transmission lines synchronized to a clock whose rate is equal to the pixel rate. LVDS transmits seven bits per clock per data line, with six bits being data and one bit used to signal if the other six bits need to be inverted in order to maintain DC balance. Low-cost TFT displays often have three data lines and therefore only directly support 18 bits per pixel. Upscale displays have four or five data lines to support 24 bits per pixel (truecolor) or 30 bits per pixel respectively. Panel manufacturers are slowly replacing LVDS with Internal DisplayPort and Embedded DisplayPort, which allow sixfold reduction of the number of differential pairs.

The bare display panel will only accept a digital video signal at the resolution determined by the panel pixel matrix designed at manufacture. Some screen panels will ignore the LSB bits of the color information to present a consistent interface (8 bit -> 6 bit/color x3).

With analogue signals like VGA, the display controller also needs to perform a high speed analog to digital conversion. With digital input signals like DVI or HDMI some simple reordering of the bits is needed before feeding it to the rescaler if the input resolution doesn"t match the display panel resolution.

TFT is an abbreviation for Thin Film Transistor, a flat panel display used to improve the operation and utility of LCD screens. In order to portray an appearance to the audience, a liquid crystal display (LCD) utilizes a crystalline-filled fluid to modify rear lighting polarized origin through the use of an electromagnetic force among two relatively thin metal wires such as indium oxide (ITO). However, color TFT displays are associated with this method, which can be employed in both divided and pixelated display systems.

With motion pictures displayed on an LCD, the intrinsic sluggish rate of increase between liquid phases over a significant number of pixel components can be an issue due to capacitance impacts, which can create a blurring of the visuals. Placing a high-velocity LCD control device inside the formation of a thin-film transistor immediately next to the cell component just on a glass screen, the issue of LCD picture speed may be substantially improved, and image blur can be eliminated for all useful purposes entirely.

Organic light-emitting diodes (AMOLEDs) are a type of flat light-emitting advanced technologies that are created by interspersing a succession of organic thin sheets over two conducting conductors. An electrical charge causes a brilliant light to be produced when the current flows. AMOLED displays are light-emitting screens that do not require a backlight, making them thinner and more energy-efficient than liquid crystal displays (LCDs) (which will need a white backlight).

AMOLED displays are not only thin and fuel-intensive, but they also deliver the highest image quality available, so they can be made translucent, elastic, bendable, or even rollable and stretchy in the future, allowing for a variety of applications. AMOLEDs are a revolutionary technology in terms of display devices! It is possible to create an AMOLED by sandwiching a sequence of thin films across phase conductors. Electric charge causes a brilliant light to be emitted when the current flows through the coil.

The color display is fantastic. Color intensity, sharpness, and luminance settings that are second to none and can be customized to meet the needs of any application.

Half-Life has been expanded. TFT displays have a far longer half-life than its LED equivalents, and they are available in a number of sizes, which might have an effect on the device"s half-life based on the phone"s usage as well as other variables. Touch panels for TFT screens can be either resistant or capacitance in nature.

Due to the apparent glass panels, there is limited functionality. For instance, there are ineffective for outdoor use because the glass can display glares from its natural lighting)

They rely on backlight to give illumination rather than generating their own light. Hence they require constructed light-creating diodes (LEDs) in their backlit display framework to ensure enough brightness.

Backlighting is unnecessary for AMOLEDs. LCDs produce images by selectively blocking parts of the illumination, whereas AMOLEDs produce light. AMOLEDs utilize less energy than LCDs since they don"t need backlighting. This is critical for battery-powered devices such as phones.

While AMOLED light-emitting sheets are lightweight, the substrate can also be elastic rather than stiff. AMOLED films are not limited to glass-like LEDs and LCDs.

AMOLEDs offer 170-degree ranges of vision. LCDs operate by obscuring the light. Hence they have intrinsic viewing obstacles. In addition, AMOLEDs have a substantially wider viewing spectrum.

AMOLEDs outperform LEDs. Since AMOLED organic coatings are less than LED inorganic crystal levels, AMOLED conducting and particle emitters layers can just be multi-layered. Also, LEDs and LCDs need glass backing, which absorbs light. AMOLEDs don"t need it.

AMOLEDs seem to be simpler to implement and larger. AMOLEDs are constructed of polymers and may be produced into big sheets. It takes a lot of extra liquid crystals to build and set down.

While red and green AMOLED sheets have a greater lifespan (46,000 to 230,000 hours), azure compounds have significantly shorter longevity (up to roughly 14,000 hours).

Due to the fact that AMOLED displays inherently emit illumination, they do not need a backlight when used on a monitor screen. Conversely, LCDs require backlights since the liquid crystals themselves are incapable of producing light under their own. Direct light emission from AMOLED displays also allows for the developing of lightweight display devices than others using TFT LCDs.

LCD displays have a higher brightness than AMOLED panels. This is owing to the LCD"s usage of led backlight, which may provide a brilliant illumination of the entire display. Despite the fact that AMOLEDs produce high levels of brilliance from their illumination, they will never be able to match the intensity of LCD lighting.

LCD screens use less power than AMOLED displays, which provides a slight advantage. The amount of energy consumed by AMOLED displays is dependent on the intensity of the screen. Lowered luminance results in lower energy usage, however, it might not be the best solution because the contrast would suffer as a result of the decreased brightness. In some situations, such as when to use an AMOLED device in direct sunlight, it is not an optimal situation.

However, the backlit keys of TFT displays account for the majority of their power usage. TFT screens" efficiency is considerably improved when the backlight is set to a lesser brightness level than the default setting. For example, replacing the light of an LCD TV with just an Led flash will have no effect on the image quality, but will result in lower power usage than replacing the light of an AMOLED TV.

With the exception of phones, numerous other technologies make use of displays to allow customers to engage in direct communication with them. To determine whether or not TFT LCD will be able to withstand the development of AMOLED innovation, we should first review the benefits of LCD technology. The backlighting quality ensures that whites are strong and brightness is superb but will deplete a battery much more quickly than just an AMOLED display. Furthermore, the cost of LCD screens is a considerable consideration. In addition to being less expensive and more easily accessible, they are produced in standard industry sizes, allowing them to be purchased for innovative products with relative ease.

Tried and trusted TFT technology works by controlling brightness in red, green and blue sub-pixels through transistors for each pixel on the screen. The pixels themselves do not produce light; instead, the screen uses a backlight for illumination.

By contrast the Active Matrix OLED (AMOLED) display requires no backlight and can light up or turn off each of their pixels independently. As the name suggests, they are made of organic material.

An AMOLED display has many other benefits which make it a superior looking display including exceptional vieiwng angles and a display that looks practically black when it is switched off.

So, why use a TFT display? Well, it is a mature technology meaning the manufacturing processes are efficient, yields high and cost much lower than AMOLED.

TFT displays also have a much longer lifespan than AMOLED displays and are available in a far greater range of standard sizes, which can be cut down to fit a space restricted enclosure for a relatively low cost adder.

Which type of display you choose really depends on your application, environment and users, so why not get in touch with us today to discuss your requirements.

Before purchasing any Smartphone, everyone goes through a list of specifications. This list includes display type, screen size, battery backup, supported operating system, total internal memory, and many others. Today, A smart digital display is the core thing for mobile, laptops or TVs.

When you are going to buy a smartphone, laptop, PC, Tab or any device that has a display, you get a little bit of confusion to buy which display is better LED or LCD. Commonly people already got the answer that LED is better because An LED display uses less power, provides a brighter display with better contrast, a thinner panel, and lesser heat dissipation than a conventional LCD display.

There is a variety of LED displays now on the market hard to choose one. There is always a war Amoled and Oled display.In this article, we will know about the feature, advantages, disadvantages, property of both AMOLED and OLED.

OLED (Organic Light-Emitting Diodes) is a flat light emitting technology, made by placing a series of organic thin films between two conductors. When an electrical current is applied, a bright light is emitted. OLEDs are emissive displays that do not require a backlight and so are thinner and more efficient than LCD displays (which do require a white backlight).

OLED displays are not just thin and efficient – they provide the best image quality ever and they can also be made transparent, flexible, foldable and even rollable and stretchable in the future. OLEDs represent the future of display technology!

Active-matrix OLED (AMOLED):AMOLEDs have full layers of the cathode, organic molecules and anode, but the anode layer overlays a thin film transistor (TFT) array that forms a matrix. They are efficient for large displays.

Transparent OLED (TOLED):Transparent OLEDs have only transparent components (substrate, cathode and anode). This technology can be used for heads-up displays.

Lightweight:One common hallmark of technological advancement is miniaturization and flexibility. Thankfully, OLED displays are fabricated on flexible plastic substrates and this is even causing researchers to consider using the material for other designs. Some other applications might include roll-up displays embedded in fabrics. OLEDs are also shatter-resistant.

Power consumptions: OLEDs are perfect for displaying an image that is fundamentally black, consuming just 40% of the power consumption of an LCD for the same image.

AMOLED is a display technology and stands for Active Matrix Organic Light-Emitting Diodes. It is a type of OLED display and is used in smartphones.AMOLEDs have full layers of the cathode, organic molecules and anode, but the anode layer overlays a thin film transistor (TFT) array that forms a matrix.

Given its astounding 100,000:1 contrast ratio, Super AMOLED displays will automatically adapt to various lighting environments to make it easier on the eyes while providing great picture quality when playing games or watching your favourite multimedia.

Energy Efficient: Because each diode or pixel generates light itself, an AMOLED panel does not require backlighting for colours and images to become visible unlike in LCD.thats why Lower power consumption or better energy efficiency, when compared against other display technologies such as LED, OLED and LCD, is one of the advantages of AMOLED.

If you are searching on the web for AMOLED VS OLED,you are actually having a wrong search because AMOLED is one type of OLED.Whatever of course there has a difference between them. AMOLED is the Advanced form of OLED.

OLED is much thinner in size, that’s why is lightweight is well. So because of being thinner, OLED is used in larger devices like TV, and laptops.AMOLED being less thinner can be used in smartphones, tablets etc. Having different aspects of uses Both OLED and AMOLED are top-level performers in their fields.

OLED comprises the thin organic light-emitting material that emits light when electricity is applied. But It is an advanced version of OLED with an additional layer of thin-film transmitter. Higher technology used in AMOLED as storage capacitors are used to maintain the pixel states.

The AMOLED display quality is much better than the OLEDs as it contains an additional layer of TFTs and follows backplane technologies.OLED display much deeper blacks as compared to AMOLED displays. You cannot see the screen in AMOLED display under direct sunlight.

AMOLED is the Advanced form of OLED. As there is a name Advanced attached to it its performance is good is well. So if you are thinking to buy a smartphone you should go for AMOLED/Super AMOLED smartphone. And for TV or Laptop, you can still go for OLED

पिछले कुछ सालों में स्मार्टफोन की डिस्प्ले काफी बेहतर हुई हैं। लेकिन प्रत्येक स्मार्टफोन डिस्प्ले के साथ जो शार्ट-फॉर्म एक संक्षिप्त नाम जुड़ता है, जैसे कि AMOLED, LCD, इत्यादि वो केवल नाम नहीं बल्कि अपने आप में एक तकनीक है। स्मार्टफोन पर लगे पैनल AMOLED, OLED, LED, LCD, IPS, TFT, LTPS, इत्यादि होते हैं। ये सभी पूर्णत: अलग होते हैं।

पहले ही इतने टाइप के पैनल मौजूद हैं, ऐसे में स्मार्टफोन निर्माता द्वारा फैंसी नामों का इस्तेमाल जैसे कि Apple द्वारा Super Retina XDR और Samsung द्वारा Dynamic AMOLED ग्राहकों के बीच भ्रम या असमंजस को और बढ़ा देता है।

डिस्प्ले के टाइप तो बहुत सारे हैं जैसे कि TFT, LTPS, AMOLED, OLED, IPS, LCD इत्यादि। लेकिन इन दिनों TFT, LTPS जैसी डिस्प्ले काफी कम हो गयीं हैं। किफ़ायती दामों पर और मिड-रेंज में आने वाले फोनों में आपको IPS LCD डिस्प्ले मिलेगी। लेकिन इन सबका विस्तार से समझें, तो मतलब क्या है ?

LCD का मतलब या फुल फॉर्म है लिक्विड क्रिस्टल डिस्प्ले (Liquid Crystal Display)। इसमें लिक्विड क्रिस्टल्स की एक श्रंखला दी जाती है जिसके पीछे एक बैकलाइट होती है। इस डिस्प्ले टाइप का हर जगह आसानी से उपलब्ध होना और कम दामों में इसका निर्माण इसे स्मार्टफोनों के लिए एक प्रचलित विकल्प या पसंद बनाता है।

स्मार्टफोनों में आपको दोनों डिस्प्ले TFT और IPS मिलती हैं। TFT का फुल फॉर्म है – Thin Film Transistor, जो LCD का ही एक बेहतर या एडवांस्ड वर्ज़न है, जो एक एक्टिव मैट्रिक्स (active matrix) का इस्तेमाल करता है। active matrix का अर्थ है कि प्रत्येक पिक्सेल एक अलग ट्रांजिस्टर और कपैसिटर से जुड़ा होता है।

TFT डिस्प्ले का सबसे बड़ा फायदा यही है कि इसके प्रोडक्शन में तुलनात्मक कम खर्च होता है और इसमें असल LCD के मुकाबले ज्यादा कॉन्ट्रास्ट मिलता है। वहीं TFT LCD में नुकसान ये है कि इन्हें रेगुलर LCD प्रकारों के मुकबाले ज्यादा एनर्जी यानि बैटरी चाहिए, इनके व्यूिंग एंगल और रंग भी इतने अच्छे नहीं होते। इन्हीं सब कारणों से बाकी डिस्प्ले विकल्पों की गिरती कीमतों के कारण अब TFT डिस्प्ले का इस्तेमाल स्मार्टफोनों में नहीं किया जाता।

TFT(Thin Film Transistor) – ये भी LCD डिस्प्ले का ही एक प्रकार है जिसमें नीचे एक पतली सेमीकंडक्टर की परत होती है जो हर एक पिक्सल पर रंगों को नियंत्रित करने का काम करता है। इसका और AMOLED में आने वाले AM यानि कि active matrix का काम लगभग एक ही है।

LTPS(Low Temperature PolySilicon) – ये भी Si (amorphous silicon) तकनीक पर आधारित TFT का ही वैरिएंट है जिसमें आपको हाई रेज़ॉल्यूशन मिलता है और ऊर्जा यानि कि पॉवर साधारणत: TFT से कम लेता है।

IGZO(Indium Gallium Zinc Oxide) – ये भी एक सेमिकंडक्टर मैटेरियल है जो डिस्प्ले के नीचे लगी फिल्म में इस्तेमाल होता है और आजकल a semiconductor material used in TFT films, which also allows higher resolutions and lower power consumption, and sees action in different types of LCD screens (TN, IPS, VA) and OLED displays

PLS (Plane to Line Switching) – PLS और IPS के नाम या उनके फुल फॉर्म लगभग एक ही जैसे लगते हैं। लेकिन इसमें आश्चर्य की कोई बात नहीं है क्योंकि इनका मुख्य कार्य भी एक समान ही है। PLS टेक्नोलॉजी को Samsung Display द्वारा बनाया गया है और IPS डिस्प्ले की ही तरह इसकी विशेषता भी डिस्प्ले पर अच्छे रंग दर्शाना और बेहतर व्यूइंग एंगल दिखाना ही हैं। लेकिन इसमें OLED और LCD/VA डिस्प्ले के मुकाबले कॉन्ट्रास्ट थोड़ा कम है।

Samsung Display का कहना है कि PLS पैनलों के उत्पादन में लागत कम लगती है, ब्राइटनेस लेवल अच्छा मिलता है और प्रतियोगी कंपनी LG Display के IPS पैनलों के मुकाबले व्यूइंग एंगल भी काफी अच्छे मिलते हैं। अंतत: PLS पैनल का उपयोग किया जाए या IPS पैनल का इस्तेमाल करें, ये पूरी तरह से स्मार्टफोन निर्माताओं पर निर्भर करता है।

AMOLED की फुल फॉर्म – एक्टिव मैट्रिक्स ऑर्गेनिक लाइट एमिटिंग डायोड (Active Matrix Organic Light-Emitting Diode) है। हालांकि ये सुनने में बहुत मुश्किल नाम लग रहा होगा, लेकिन ये है नहीं। हम पहले ही TFT LCD टेक्नोलॉजी में एक्टिव मैट्रिक्स के बारे में पढ़ चुके हैं और अब रहा OLED, तो ये केवल एक पतली फिल्म वाली डिस्प्ले तकनीक है और कुछ नहीं।

और क्योंकि OLED डिस्प्ले में काले पिक्सल बंद हो जाते हैं, उनमें करंट नहीं आता, इसीलिए कॉन्ट्रास्ट लेवल भी LCD डिस्प्ले के मुकाबले ज्यादा मिलता है। AMOLED डिस्प्ले में रिफ्रेश रेट तो ज़्यादा मिल जाता है, लेकिन वहीँ LCD डिस्प्ले को, AMOLED की तुलना में ज्यादा ब्राइट बनाया जा सकता है। क्योंकि ये एक ऑर्गेनिक मैटीरियल से बने होते हैं, एक लम्बे समय के इस्तेमाल के बाद इनकी ब्राइटनेस घटने लगती है जिससे कई बार स्क्रीन बर्न-इन जैसी समस्याएं भी आ सकती हैं। हालाँकि ये समस्या पुराने स्मार्टफोनों में ज्यादा आती थी, अब ऐसा ना के बराबर होता है।

वहीँ इसकी अच्छी बात ये है कि AMOLED डिस्प्ले LCD के मुकाबले पतली होती हैं क्योंकि इनमें अंदर बैकलिट की परत लगाने की ज़रुरत नहीं पड़ती और इन्हें फ्लेक्सिबल यानि कि लचीला भी बनाया जा सकता है।

OLED को- Organic Light Emitting Diode कहते हैं। एक OLED डिस्प्ले electroluminescent मैटीरियल की पतली शीट से बनी होती है, जिसका सबसे बड़ा फायदा यही है कि ये अपनी रौशनी खुद पैदा करते हैं और इन्हें बैकलाइट की ज़रुरत नहीं पड़ती, जिससे ऊर्जा या बिजली की ज़रुरत कम पड़ती है। यही OLED स्क्रीन जब स्मार्टफोन या टीवी के लिए उपयोग होती है तो इसे ज़्यादातर AMOLED डिस्प्ले के नाम से जाना जाता है।

जैसे कि हमने पहले भी बताया AMOLED में AM एक्टिव मैट्रिक्स (Active Matrix) के लिए इस्तेमाल होता है। हालाँकि ये पैसिव मैट्रिक्स (Passive Matrix) OLED से अलग होता है जिसे p-OLED कहा जाता है। ये स्मार्टफोनों में थोड़ा कम प्रचलित है।

वहीं Super AMOLED, दक्षिणी कोरियाई कंपनी Samsung द्वारा दिया गया है एक नाम है जो अब कंपनी के मिड-रेंज से प्रीमियम रेंज के स्मार्टफोनों में देखने को मिलता है। IPS LCD की ही तरह, Super AMOLED डिस्प्ले में साधारण AMOLED डिस्प्ले पर टच रिस्पांस लेयर को जोड़कर एक किया जाता है, इसमें अलग से एक परत नहीं लगाई जाती। और इसका नतीजा ये होता है कि Super AMOLED स्क्रीन सूरज की रौशनी या आउटडोर में AMOLED के मुकाबले बेहतर नज़र आती हैं और साथ ही ये पावर भी कम लेती हैं।

जैसे कि Samsung ने इस स्मार्टफोन डिस्प्ले टाइप का नाम -Super AMOLED रखा है। साधारण भाषा में ये AMOLED स्क्रीन का सुधार किया गया या कहें कि बेहतर वर्ज़न है। और ये केवल मार्केटिंग के लिए मारने वाली डींगें नहीं हैं, बल्कि कई उत्पादों की समीक्षा (review) करने बाद, तथ्य यही है कि Samsung की डिस्प्ले बाज़ार में सबसे उत्तम श्रेणी में आती हैं।

वहीँ इसकी तकनीक में किये गए सबसे नए विकास या सुधार को कंपनी ने Dynamic AMOLED का नाम दे दिया। . हालांकि Samsung ने इसके बारे में कभी विस्तार से नहीं बताया है लेकिन इतना साफ़ कर दिया है कि इस तरह की डिस्प्ले में HDR10+ सर्टिफिकेशन शामिल होता है जिसके साथ आपको स्क्रीन पर रंगों और कॉन्ट्रास्ट की एक वाइड रेंज मिलती है। साथ ही इसमें ब्लू लाइट कम होती जिससे ये डिस्प्ले आँखों के लिए ज्यादा आरामदायक हो।

ठीक इसी तरह OnePlus ने भी हाई-एंड स्मार्टफोनों के लिए नाम रखा है – Fluid AMOLED, जिसमें हाई रिफ्रेश रेट ही इसकी ख़ास बात है, इसमें कोई और अंतर नहीं होता। उदाहरण के लिए – डिस्प्ले अगर 120Hz रिफ्रेश रेट के साथ आएगी तो उसमें आपको और ज्यादा स्मूथ एनीमेशन मिलेगा।

पिक्सल डेंसिटी की बात करें तो, 2010 में iPhone 4 के लॉन्च के समय Apple का मुख्य आकर्षण यही था। इस स्मार्टफोन डिस्प्ले में कंपनी ने LCD डिस्प्ले का इस्तेमाल किया। इस LCD पैनल ((LED, TFT, और IPS) को हाई रेज़ॉल्यूशन (उस समय पर 960 X 640 पिक्सल्स) के साथ Retina Display का नाम दिया। इस फ़ोन में 3.5 इंच की डिस्प्ले थी।

उस समय पर Apple के मार्केटिंग डिपार्टमेंट ने Retina Display नाम इसलिए चुना क्योंकि कंपनी के अनुसार एक निश्चित दूरी से हमारी या किसी भी इंसान की आंखें अलग-अलग पिक्सल में फर्क नहीं कर पाती। iPhones के केस में, ये नाम तब इस्तेमाल होता था जब फ़ोन की डिस्प्ले पर 300 ppi (pixel per inch) से ज्यादा होती थी।

जब सबने हाई रेज़ॉल्यूशन के साथ डिस्प्ले लेना आरम्भ कर दिया, फिर Apple ने खुद को भीड़ में अलग करने के लिए अपने प्रीमियम स्मार्टफोनों में इस्तेमाल होने वाली OLED डिस्प्ले को “Super Retina” का नाम दे दिया। ये डिस्प्ले iPhone X और उसके बाद आने वाले फोनों में आयी है। ये डिस्प्ले हाई कॉन्ट्रास्ट रेट और डिस्प्ले पर रंगों की सटीकता के लिए जानी जाती है, और ऐसी ही स्क्रीन Samsung के S-सीरीज़ के स्मार्टफोनों में भी आप देख सकते हैं।

इसके बाद कंपनी ने iPhone 11 Pro के साथ डिस्प्ले का नया नाम भी लॉन्च किया – “Super Retina XDR”। इसमें भी वही OLED पैनल का उपयोग किया गया है, लेकिन इसे पैनल का निर्माण Samsung Display या LG Display द्वारा हुआ है। इसमें आपको 2,000,000:1 रेश्यो के साथ और भी बेहतर कॉन्ट्रास्ट लेवल और 1200 nits की ब्राइटनेस मिलते हैं और ये ख़ासकर HDR कंटेंट के लिए अनुकूल हैं।

साथ ही दूसरी चुनौती ये है कि इनकी कीमत भी काफी ज्यादा होती है। उदाहरण के लिए – Samsung की microLED TVs (146 इंच से 292 इंच) की कीमत 3.5 करोड़ से 12 करोड़ है, जो कि बहुत ही ज़्यादा है।

जैसे कि हमने पहले भी कहा, OLED या AMOLED डिस्प्ले में सबसे बड़ा फ़ायदा है कि हर पिक्सल खुद को रौशनी देने का कार्य संभालता है और इससे कंट्रास्ट लेवल बढ़ता है। साथ ही दूसरा फ़ायदा है ज़्यादा और सटीक काला रंग, जो कि डिस्प्ले पर देखते समय अच्छी पिक्चर क्वालिटी के लिए बेहद महत्वपूर्ण है। साथ ही जिस समय स्क्रीन कोई गहरे (डार्क) रंग की तस्वीर दिखाती है तो ये ये ऊर्जा भी कम लेते हैं।

वहीँ इनकी ख़ामियों की बात करें तो, इनको बनाने में काफी ज़्यादा लागत लगती है और कॉम्पोनेन्ट की पूर्ती करने वाली कंपनियां भी सीमित ही हैं। इनमें Samsung Display, LG Display और तीसरे नंबर पर चीन की इलेक्ट्रॉनिक्स कंपनी BOE और कुछ एक जो OLED की मांग को पूरा करते हैं। जबकि LCD पैनल बनाने वाली काफी कम्पनियां हैं।

TFT, IPS aur Super Amoled display me kaun hai best : अगर आप एक smartphone यूजर हैं। तो आपको फोन के डिसप्ले स्क्रीन के बारे में कुछ ना कुछ तो जरुर पता ही होगा। आज के डेट में डिसप्ले स्क्रीन का यूज laptop, computer से लेकर mobile तक, कई सारे डिवाइस में हो रहा है। इसी कारण डिसप्ले स्क्रीन को पहले से और ज्यादा बेहतर बनाने के लिए इनमे काफी बदलाव किये गये है।

अब हर कंपनियां ऐसी डिसप्ले स्क्रीन बनाने की कोशीस कर रही हैं। जिसे स्क्रैच और टूटने फूटने से बचाया जा सके। आज कल डिसप्ले स्क्रीन का सबसे ज्यादा यूज mobile device के लिए हो रहा है। इसी लिए आज हम यह जाने की कोशीस करेगे की, TFT, IPS aur Super Amoled display में कौन सी स्क्रीन है सबसे बेस्ट।

देखा जाये तो मार्केट में इस समय तीन तरह की डिसप्ले स्क्रीन ज्यादा मौजूद है, TFT, IPS और Super Amoled. लेकिन कई बार लोगों को ये पता ही नहीं होता है, कि कौन सी स्क्रीन सबसे बेस्ट है और वो कौन सा मोबाइल खरीदें।

इसलिए आज हम आपको TFT, IPS और Super Amoled डिसप्ले स्क्रीन के बारे में बताने जा रहे हैं। ताकि आप यह जान सके कि, कौन सी स्क्रीन है सबसे बेस्ट TFT, IPS और Super AMOLED. तो चलिए जान लेते है की, ips tft vs super amoled display which is better in hindi.

कौन सी स्क्रीन है सबसे बेस्ट TFT, IPS और Super AMOLED. चलिए एक एक करके हम लोग जान लेते है की, इन तीनो डिस्प्ले में से कौन सबसे अच्छा है। ताकि आप आसानी से यह जान सके की, कौन सी डिस्प्ले स्क्रीन वाली फ़ोन खरीदना चाहिए।

पहले के फोन में टीएफटी डिसप्ले देखने को मिलता है। ज्यादातर सस्ते और एंट्री लेवल फोन में TFT डिसप्ले लगा होता है। यह डिस्प्ले काफी सस्ता तो जरुर है। लेकिन क्वालिटी के मामले में, यह बिलकुल भी अच्छी नहीं होता है।

देखा जाये तो IPS एलसीडी और Super Amoled डिसप्ले, दोनों का ही क्वालिटी बहुत बढ़िया होता हैं। लेकिन फिर भी दोनों में काफी फर्क है। जहा IPS एलसीडी डिसप्ले थोड़ा मोटा होता है। तो वहीं Super Amoled डिसप्ले काफी पतला होता है, और इनके फोन भी पतले आते हैं।

लेकिन इसी कारण IPS एलसीडी में फोन की बैटरी भी जल्दी डाउन हो जाती है। क्योंकि जब फोन की स्क्रीन ऑन होता है। तो IPS एलसीडी भी सारी ऑन रहती है। जिसके कारण ज्यादा पावर का यूज होता है और बैटरी जल्दी डाउन हो जाता है। लेकिन वहीं दुसरी और Super Amoled display में ऐसा नहीं होता है।

सुपर एमोलेड डिसप्ले ज्यादातर हाई बजट के फोन में आते है। इसीलिए Super Amoled डिसप्ले के लिए, आपको थोड़ा महंगा फोन खरीदना पड़ेगा। सुपर एमोलेड डिसप्ले में कलर आखों के लिए अच्छे होते हैं और पिक्चर में मौजूद सभी कलर नैचुरल नजर आते हैं।

Super Amoled में IPS एलसीडी से ज्यादा चमक होती है। Super amoled screen के साथ आने वाले स्मार्टफोन की बैटरी लाइफ भी अच्छी होती है। क्योंकि फोन का सिर्फ उतना ही स्क्रीन ऑन रहता है। जितने में कलर नजर आते है। जैसे अगर आप के फ़ोन स्क्रीन पर डार्क कलर का इमेज है। तो फोन बहुत कम पावर लेगा।

आशा करता हु दोस्तों “TFT, IPS aur Super Amoled display me kaun hai sabse best”, अब आप को पता चल गया होगा। और अब आप अपने जरुरत के हिसाब से एक अच्छा डिस्प्ले स्क्रीन वाला फ़ोन ख़रीद पायेगे।
