super amoled display vs pls tft display quotation

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.

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.

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.

IPS (In-Plane Switching) lcd is still a type of TFT LCD, IPS TFT is also called SFT LCD (supper fine tft ),different to regular tft in TN (Twisted Nematic) mode, theIPS LCD liquid crystal elements inside the tft lcd cell, they are arrayed in plane inside the lcd cell when power off, so the light can not transmit it via theIPS lcdwhen power off, When power on, the liquid crystal elements inside the IPS tft would switch in a small angle, then the light would go through the IPS lcd display, then the display on since light go through the IPS display, the switching angle is related to the input power, the switch angle is related to the input power value of IPS LCD, the more switch angle, the more light would transmit the IPS LCD, we call it negative display mode.

The regular tft lcd, it is a-si TN (Twisted Nematic) tft lcd, its liquid crystal elements are arrayed in vertical type, the light could transmit the regularTFT LCDwhen power off. When power on, the liquid crystal twist in some angle, then it block the light transmit the tft lcd, then make the display elements display on by this way, the liquid crystal twist angle is also related to the input power, the more twist angle, the more light would be blocked by the tft lcd, it is tft lcd working mode.

A TFT lcd display is vivid and colorful than a common monochrome lcd display. TFT refreshes more quickly response than a monochrome LCD display and shows motion more smoothly. TFT displays use more electricity in driving than monochrome LCD screens, so they not only cost more in the first place, but they are also more expensive to drive tft lcd screen.The two most common types of TFT LCDs are IPS and TN displays.

When we purchase a new smartphone we go through a list of specifications that includes the processor, software, cameras, display type, battery, etc. The display of the smartphone is something which has always been a concern for people. And smartphone technology has advanced so much in the past decade that you get several display technology options to choose from.

Today, a smartphone is not just a means to send and receive calls and texts. It has become a general necessity, so choosing the right technology should be your main priority. Coming back to displays, as we said there are plenty of display types available right now.

Two of the main contenders for display technologies that are widely available are AMOLED and LCD. Here in this article, we will be comprising AMOLED vs LCD and find out which one is better for you.

Starting with the AMOLED first, it is a part of the OLED display technology but with some more advanced features. To completely know about it must understand its all three components. The first one is LED, “Light Emitting Diode”. Then we have “O” which stands for organic and makes the OLED.

It actually means that organic material is placed with two conductors in each LED, which helps to produce the light. And the “AM” in AMOLED means Active Matrix, it has the capability to increase the quality of a pixel.

The AMOLED display is similar to the OLED in various factors like high brightness and sharpness, better battery life, colour reproduction, etc. AMOLED display also has a thin film transistor, “TFT” that is attached to each LED with a capacitor.

TFT helps to operate all the pixels in an AMOLED display. This display might have a lot of positives but there are a few negatives too let’s point both of them out.

A major issue with these displays is of burning of pixels. After showing a specific image or colour for a longer period of time, the pixel can get burned. And if there is a problem with a single pixel it will affect the entire display.

Low outdoor visibility, usually the AMOLED Displays are quote not bright in direct sunlight and outdoor readability could be a problem for some devices but average screen brightness.

The LCD stands for “Liquid Crystal Display”, and this display produces colours a lot differently than AMOLED. LCD display uses a dedicated backlight for the light source rather than using individual LED components.

The LCD displays function pretty simply, a series of thin films, transparent mirrors, and some white LED lights that distributes lights across the back of the display.

As we have mentioned, an LCD display always requires a backlight and also a colour filter. The backlight must have to pass through a thin film transistor matrix and a polarizer. So, when you see it, the whole screen will be lit and only a fraction of light gets through. This is the key difference comparing AMOLED vs LCD and this is what differentiates these two display technologies.

The LCD displays are cheaper compared to the AMOLED as there is only one source of light which makes it easier to produce. Most budget smartphones also use LCD displays.

LCD displays have bright whites, the backlight emits lots of light through pixels which makes it easy to read in outdoors. It also shows the “Accurate True to Life” colours, which means it has the colours that reflect the objects of the real world more accurately than others.

LCDs also offer the best viewing angle. Although it may depend on the smartphone you have. But most high-quality LCD displays support great viewing angles without any colour distortion or colour shifting.

The LCD displays can never show the deep blacks like AMOLED. Due to the single backlight, it always has to illuminate the screen making it impossible to show the deep blacks.

The LCDs are also thicker than other displays because of the backlight as it needs more volume. So, LCD smartphones are mostly thicker than AMOLED ones.

Both of these display technologies have their own Pros and Cons. Taking them aside everything ends up with the user preferences as people might have different preferences among different colours and contrast profiles. However, a few factors might help you to decide which one fits perfectly for you.

Let’s start with the pricing. Most AMOLED display smartphones always cost more than an LCD smartphone. Although the trend is changing a bit. But still, if you want to get a good quality AMOLED display you have to go for the flagship devices.

The colors are also very sharp and vibrant with the AMOLED displays. And they look much better than any LCD display. The brightness is something where LCDs stood ahead of the AMOLED display. So using an LCD display outdoors gives much better results.

The last thing is battery consumption, and there is no one near the AMOLED displays in terms of battery. As of now, all smartphones feature a Dark Mode and most of the apps and UI are dark black with a black background. This dark UI on smartphones doesn’t require any other light, it gives the AMOLED displays a boost in battery performance.

Looking at all these factors and comparing AMOLED vs LCD displays, the AMOLED displays are certainly better than the LCDs. Also, the big display OEMs, like Samsung and LG are focusing more the OLED technologies for their future projects. So, it makes sense to look out for AMOLED displays. That being said, if we see further enhancements in the LCD technology in terms of battery efficiency and more, there is no point to cancel them at this moment.

AMOLED (Active Matrix Organic Light Emitting Diode) and TFT (Thin Film Transistor) are the two types of displays that are used in mobile phones. TFT is actually a process of producing the displays and is used even by AMOLED but for most purposes, TFT is used to refer to LCD displays. The difference between them is the material as AMOLED uses organicmaterials, mainly carbon, while TFT does not.

There are differences between the two that are quite tangible. For starters, AMOLED generates its own light rather than relying on a backlight like a TFT-LCD does. This consequently means that AMOLED displays are much thinner than LCD displays; due to the absence of a backlight. It also results in much better colors than a TFT is capable of producing. As each pixel’s color and light intensity can be regulated independently and no light seeps from adjacent pixels. A side by side comparison of the two displays with the same picture should confirm this. Another effect of the lack of a backlight is the much lower power consumption of the device. This is very desirable when it comes to mobile phones where every single feature competes for the limited capacity of the battery. As the screen is on 90% of the time that the device is being used, it is very good that AMOLED displays consume less. Just how much of a difference is not very fixed though as it really depends on the color and intensity of the image. Having a black background with white text consumes much less energy than having black text on a white background.

The biggest disadvantage that AMOLED has is the shorter lifespan of the screen compared to TFT. Each pixel in the display degrades with each second that it is lit and even more so the brighter it is.  Despite improvements on the lifetime of AMOLED displays, AMOLED still only lasts a fraction of the lifetime of a TFT display. With that said, an AMOLED display is able to outlast the usable lifetime of the device before parts of it start to degrade.

The main hindrance to the massive adaptation of AMOLED is the low production numbers. TFT has been in production for much longer and the infrastructure is already there to meet the demands.

Key Difference: AMOLED is a type of screen used in consumer electronics, such as smartphones, tablets, and laptops. Gorilla Glass is a type of protection that is used on the screen.

There are many different types of screens available, such as TFT LCD, IPS-LCD, Resistive Touchscreen LCD, OLED, AMOLED, Super AMOLED, etc. Each of these types has something that helps them stand apart from the others.

AMOLED stands for Active-Matrix Organic Light-Emitting Diode or "Active Matrix OLED" for short. It is a hybrid display technology that combines the active matrix backplane from a traditional TFT display with an OLED display. The advantage of this is that it has a faster pixel switching response time than the traditional OLED displays.

Currently, AMOLED is very popular for use in mobile phones, media players and digital cameras. However, it is not currently popular for use in larger applications such as televisions or laptops.

AMOLED screen have been made popular by phone manufactures, such as Samsung, who tout its benefits. Samsung uses what it calls a Super AMOLED display in its popular Samsung Galaxy line of phones. Super AMOLED is essentially an AMOLED display that Samsung has integrated it with a digitizer, which means that the layer that detects touch is integrated into the screen, rather than overlaid on top of it.

As compared to other screens on the market, AMOLED has a faster pixel switching response than traditional OLED displays, consumes less power and has better contrast ratios than LCDs. However, AMOLED displays may be difficult to view in direct sunlight as they have reduced brightness. Also organic materials used in AMOLED displays are very prone to degradation, which may result is fading of one color over the others.

As anyone with a cracked screen knows, displays are very easy to damage. Hence, it is essential that the companies that charge so much for their product provide some form of protection on their screens. This is where Gorilla Glass comes in.

Gorilla Glass is an alkali-aluminosilicate sheet toughened glass. It is scratch resistant as well as impact resistant, which means that it will protect the display of the device against the accidental scratches made with keys in the pocket or accidentally dropping the phone.

Gorilla Glass was developed and is manufactured by Corning Inc. It was developed from a chemically strengthened glass called "Chemcor" that Corning developed in the 1960’s. Today, Gorilla Glass is used primarily for portable electronic devices, including mobile phones, portable media players, portable computer displays, and some television screens.

The main difference between Gorilla Glass and AMOLED is the fact that AMOLED is a type of display used in electronics, whereas Gorilla Glass is a type of toughened glass that acts as a screen protection, usually laid on top of the display such as AMOLED.

AMOLED (active-matrix organic light-emitting diode, OLED display device technology. OLED describes a specific type of thin-film-display technology in which organic compounds form the electroluminescent material, and active matrix refers to the technology behind the addressing of pixels.

An AMOLED display consists of an active matrix of OLED pixels generating light (luminescence) upon electrical activation that have been deposited or integrated onto a thin-film transistor (TFT) array, which functions as a series of switches to control the current flowing to each individual pixel.

Typically, this continuous current flow is controlled by at least two TFTs at each pixel (to trigger the luminescence), with one TFT to start and stop the charging of a storage capacitor and the second to provide a voltage source at the level needed to create a constant current to the pixel, thereby eliminating the need for the very high currents required for passive-matrix OLED operation.

TFT backplane technology is crucial in the fabrication of AMOLED displays. In AMOLEDs, the two primary TFT backplane technologies, polycrystalline silicon (poly-Si) and amorphous silicon (a-Si), are currently used offering the potential for directly fabricating the active-matrix backplanes at low temperatures (below 150 °C) onto flexible plastic substrates for producing flexible AMOLED displays.

AMOLED was developed in 2006. Samsung SDI was one of the main investors in the technology, and many other display companies were also developing it. One of the earliest consumer electronics products with an AMOLED display was the BenQ-Siemens S88 mobile handsetiriver Clix 2 portable media player.Nokia N85 followed by the Samsung i7110 - both Nokia and Samsung Electronics were early adopters of this technology on their smartphones.

Manufacturers have developed in-cell touch panels, integrating the production of capacitive sensor arrays in the AMOLED module fabrication process. In-cell sensor AMOLED fabricators include AU Optronics and Samsung. Samsung has marketed its version of this technology as "Super AMOLED". Researchers at DuPont used computational fluid dynamics (CFD) software to optimize coating processes for a new solution-coated AMOLED display technology that is competitive in cost and performance with existing chemical vapor deposition (CVD) technology. Using custom modeling and analytic approaches, Samsung has developed short and long-range film-thickness control and uniformity that is commercially viable at large glass sizes.

The amount of power the display consumes varies significantly depending on the color and brightness shown. As an example, one old QVGA OLED display consumes 0.3 watts while showing white text on a black background, but more than 0.7 watts showing black text on a white background, while an LCD may consume only a constant 0.35 watts regardless of what is being shown on screen.

AMOLED displays may be difficult to view in direct sunlight compared with LCDs because of their reduced maximum brightness.Super AMOLED technology addresses this issue by reducing the size of gaps between layers of the screen.PenTile technology is often used for a higher resolution display while requiring fewer subpixels than needed otherwise, sometimes resulting in a display less sharp and more grainy than a non-PenTile display with the same resolution.

The organic materials used in AMOLED displays are very prone to degradation over a relatively short period of time, resulting in color shifts as one color fades faster than another, image persistence, or burn-in.

As of 2010, demand for AMOLED screens was high and, due to supply shortages of the Samsung-produced displays, certain models of HTC smartphones were changed to use next-generation LCD displays from the Samsung-Sony joint-venture SLCD in the future.

Flagship smartphones sold in 2020 and 2021 used either a Super AMOLED. Super AMOLED displays, such as the one on the Samsung Galaxy S21+ / S21 Ultra and Samsung Galaxy Note 20 Ultra have often been compared to IPS LCDs, found in phones such as the Xiaomi Mi 10T, Huawei Nova 5T, and Samsung Galaxy A20e.ABI Research, the AMOLED display found in the Motorola Moto X draws just 92 mA during bright conditions and 68 mA while dim.

"Super AMOLED" is a marketing term created by Samsung for an AMOLED display with an integrated touch screen digitizer: the layer that detects touch is integrated into the display, rather than overlaid on top of it and cannot be separated from the display itself. The display technology itself is not improved. According to Samsung, Super AMOLED reflects one-fifth as much sunlight as the first generation AMOLED.One Glass Solution (OGS).

Future displays exhibited from 2011 to 2013 by Samsung have shown flexible, 3D, transparent Super AMOLED Plus displays using very high resolutions and in varying sizes for phones. These unreleased prototypes use a polymer as a substrate removing the need for glass cover, a metal backing, and touch matrix, combining them into one integrated layer.

Also planned for the future are 3D stereoscopic displays that use eye-tracking (via stereoscopic front-facing cameras) to provide full resolution 3D visuals.

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.

AMOLED generates its own light while TFT relies on a backlight. AMOLED is thinner than TFT. AMOLED produces better colors than TFT. AMOLED consumes less power than TFT.

It’s a constant debate. AMOLED Displays feature remarkable colors, deep blacks and eye searing contrast ratios. IPS LCD Displays feature more subdued(though some would say more accurate) colors, better off-axis viewing angles and often times a brighter overall picture.

A variant of liquid crystal display (LCD), the technology uses TFT technology to enhance image quality. It offers better image quality and higher resolutions as compared to earlier generation LCD displays. However TFT screens consume lot energy, which results in poor battery life.

This is technology much more advanced than the panels in today’s TVs. The Super PLS displays Samsung makes (what the 7.0 Plus has) are also very good, some say better than the IPS displays in tablets, but it’s still an LCD, not quite as good as the Super AMOLED Plus in my opinion.

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.

One other term you will encounter is Super AMOLED, which is Samsung’s marketing term for a display that incorporates the capacitive touchscreen right into the display, instead of it being a separate layer on top of the display. This makes the display thinner.

IPS nowdays are used in middle and high end phones, TFT in cheap low end phones and SUPED AMOLED and AMOLED in high end. So if I must conclude – the market is almos limitting your choice to IPS or SUPER AMOLED, AMOLED.

आजकल बाज़ार में कई प्रकार के डिस्प्ले मौजूद हैं, जिस वजह से कुछ लोग कन्फ्यूजन में होते है कि किस प्रकार का Display वाला स्मार्टफोन लेना चाहिए, इन Displays का उपयोग बहुत से प्रोडक्ट्स में किया जाता है जैसे कि कंप्यूटर, मोबाइल स्मार्ट वाच आदि आदि.

AMOLED, OLED का ही Advanced Version है जिसका फुल-फॉर्म है Active Matrix Organic Light Emitting Diode. दोनों एक ही Machenism पर काम करते हैं इन Dispalys में Backlight नहीं होती इसके हर Pixels में खुद का एक Transister लगा होता है जिसकी वजह से Display के जिन जगहों पर Colours की जरुरत होती, Pixels वहीं की Light को ON करते है,

AMOLED डिस्प्ले मे रंग वास्तविक तो नहीं मिलते लेकिन थोड़ा Vibrant और Over Saturated Colour रहता है जो हमारे इंसानी आंखो को अत्यधिक प्रिय लगते है. ये Display बहुत ही लचीली होती है अतः जल्दी टूटती नहीं और कभी टूट गयी तो बनवाना थोड़ा महंगा पड़ जाता है।

OLED डिस्प्ले उपर के 3 Displays से अच्छे रंग दिखाता है इस वजह से कुछ महंगा है, OLED Display थोडा पतला होने के साथ साथ इसका View Angle भी अच्छा होता है,

पिछले कुछ वर्षों तक सारे Display, LCD टेक्नोलॉजी पर काम करते थे लेकिन इसका Machenism थोड़ा अलग है OLED में आपको कोई भी Backlight नहीं मिलती है जिसके कारण हल्का ओर पतला मिल जाता है।

किसी भी प्रकार के Display में इन तीन चीज़ों का होना अति आवश्यक होता है पहला - डिस्प्ले को रोशनी देने के लिए एक लाईट जिससे Display को देखा जा सके, दूसरा - कलर्स,आपको डिस्प्ले में रंग दिखाइ देगी अगर रंग ही नहीं होंगे तो पूरा डिस्प्ले सफेद दिखेगा या काला, अतः डिस्प्ले में रंगों का होना बहुत जरूरी है.

Tft display (Thin Film Transister) होता है इसको LCD Display का नया वर्शन माना जाता है क्योंकि TFT डिस्प्ले दुसरे Displays के मुकाबले सस्ता मिलता है और इसकी मोटाई भी कुछ ज्यादा होने के वजह से मोबाईल के आकर में भी फर्क आ जाता है अतःइस डिस्प्ले का इस्तेमाल पहले के Smartphones और आजकल के सस्ते Mobiles में किया जाता है,

चूंकि यह डिस्प्ले थोडा सस्ते में मिल जाता है अतः इसमें कुछ खामियां भी है रंगों और क्वालिटी के हिसाब से, अगर जब कभी आप नया फ़ोन लेने जाएँ तो ये सुनिश्चित कर लें कि मोबाइल tft डिस्प्ले वाला ना हो, क्योकि इसमें आपको थोड़ा फीका और विडियो का अनुभव ठीक से नहीं ले पाएंगे, साथ ही ये डिस्प्ले जल्दी टूट जाता है।

आईपीएस एलसीडी ये एलसीडी का ही एक रूप है इसमें भी वही टेक्नोलॉजी काम करती है जो एलसीडी डिस्प्ले में करती थी, यह डिस्प्ले आज के इस दौर में Trend में है क्योंकि ये AMOLED display के मुकाबले सस्ते और रंगों को बहुत Natural दिखाते है,

जबकि AMOLED डिस्प्ले मे Colours ज्यादा बूस्टेड और Over Saturated रहता है अगर आप भी अपने मोबाइल में एक्यूरेट कलर्स देखना चाहते है तो आपको IPS LCD Display के साथ ही जाइये.

इस Display में भी एक Backlight होता है जिसके कारण सूर्य की तेज किरणों में भी इस Display को बिना किसी दिक्कत के क्लियर देख पाएंगे, और View Angle को बढ़ाया गया है अर्थात आप जब Smartphone को कुछ Tilt भी करते है तो ठीक से देख पायेंगे,

यह Display भी AMOLED के मुकाबले सस्ती ओर TFT Display से महंगा मिल जाता है और AMOLED से कुछ कम ओर TFT से थोड़ा मोटा रहता है जिसके कारण Smartphones भी थोड़े भारी हो जाते है.

बहुत से डिस्प्ले के बारे में जानने के बाद भी बहुत से लोग इसी Confusion में होंगे कि कौन सी Types of mobile display screen वाला मोबाइल लें, अगर आपके दिमाग में ये सवाल है तो फ़िक्र मत कीजिये हम आपको आपके Use के According सही डिस्प्ले की जानकारी देंगे,

अगर 3000-4000Rs.के अंदरथोड़े सस्ते मोबाइल चाहिए तो आप tft डिस्प्ले ही लें क्योंकि इस Price में किसी और Display का विकल्प ही नहीं है इसमें भी आपको अच्छा Experince मिलेगा,आपकी Budget 10K से उपर है तो आप IPS LCD का चुनाव करें क्योंकि इस कीमत में आपको AMOLED Display मुश्किल से ही मिल पाता है.

25K के उपर का बजट होगा तो AMOLED, Super AMOLED और Retina Display वाला Smartphone ले सकते है क्योंकि ये सभी Battery की खपत को कम करता है और Vibrant Colour दिखाता है जो इंसानी आंखो को अत्यधिक प्रिय लगते है ये सभी Display आंखो के लिए भी सेहतमंद होते है।

अब बारी आती है Display को सुरक्षित रखने की, एक अच्छी डिस्प्ले स्क्रीन वाला फोन ही काफी नहीं है हमें यह भी देख लेना चाहिए कि फोन में कौन सा Protector Glass लगा है, Market में आपको बहुत सारे Glass मिल जाएंगे लेकिन आज हम सिर्फ Gorilla GlassProtector ग्लास के बारे में जानकारी देंगे जो काफी कठोर ओर सबसे ज्यादा यूज़ किया जाता है.

इसका यूज़ सबसे पहले 2007 में iPhone में किया गया था, Gorilla Glass बनाने वाली Company Corning यहकभीनहीं बोलती की हमारे Glass में Scratch नहीं पड़ेगा ये जोग्लासहै वो काफी हद तक आपके Display में Scratch आने से बचाती है लेकिन एक भी Scratch ना आए ऐसा Possible नहीं है,

हमें उम्मीद है की आपको इस लेख Mobile Display Types - IPS, Retina, and AMOLED in Hindiसे काफी उपयोगी जानकारी मिली होगी. आपको हमारा यह लेख कैसा लगा हमें Comment में जरुर बताएं, साथ ही अगर लेख पसंद आया हो तो इसे Social साइट्स और दोस्तों के साथ Share करना ना भूलें

Both screens are coated in Gorilla Glass 3 but while the Edge+ gets the Super AMOLED treatment, the Style has a TFT LCD. We were impressed with both during our hands-on time with the devices, but that was indoors in a well-lit environment. Outdoors is a different matter and we’ll have to wait to report back on that.

That curve makes has more of an effect on the Edge+‘s design than it does on its display performance. It looks beautifully futuristic, but in a subtle way – like something out of the excellent 2014 film Herrather than a prop from the original Star Trek. It’s not the only classy piece of design here, because the Edge+ takes its design cues from the Galaxy S6 Edge rather than last year’s Note Edge, and as such gets a welcome metal-and-glass makeover.

It’s also impressively thin – just 6.9mm – but bear in mind that the combination of those curves, the glass back and the big display make it a prime candidate for smashed-screen-syndrome.
