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.
Both technologies have their own advantages and disadvantages. So, how do you know which one is best for your needs? We compare these two technologies below.
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.

Compared to traditional TFT screens, AMOLED displays black, thick and solid black, while TFT is more like dark gray. The white of AMOLED is also pure white, resulting in a more transparent display. Ultrathin
AMOLED displays are thinner than LCD displays. LCD displays contain backlights, color filters, ultra-thin design backlight modules and liquid crystal materials that amOLeds do not need because of their self-emitting body principle. Integrated touch technology also makes AMOLED displays thinner and thinner. The world"s first AMOLED integrated touch screen was introduced in 2010 and has been used in high-end smart phones. Phones
It"s not impossible to see maps and addresses on a phone in bright light. Outdoor readability is proportional to chromaticity X brightness, and THE chromaticity of OLED is 1.7 times that of LCD. The AMOLED display is good for outdoor readability, allowing colors to appear clearly even in bright sunlight, providing a better perspective for outdoor reading.
AMOLED displays use significantly less energy than traditional LCD screens because each pixel of an AMOLED display can be independently controlled without a constant backlight. When browsing a web page with a white background, such as Baidu, most pixels need to be 100 percent bright. On the other hand, when a darker video is played, the pixels glow less. In this case, the emission brightness of the LCD screen is 100%, and the local brightness is regulated by controlling the rotation direction of the LIQUID crystal molecules.
Each pixel in an AMOLED display can independently adjust its brightness, which means it doesn"t need to emit 100 percent brightness, saving energy on the device. Even watching videos or enjoying multimedia does not cause a huge loss of battery life. In an emergency, the phone can be used for up to 24 hours by enabling a power saving mode as low as 10 percent to avoid unnecessary pixel power consumption.
2)High-resolution AMOLED uses the Pentile arrangement, unlike the traditional LCD where one pixel is equal to a collection of three sub-pixels, red, green and blue. Instead, one pixel is equal to 1 green 0.5(blue-red), with a large emphasis on green to make the picture look brighter.
3)AMOLED self-lighting, individual pixels do not work when displaying black, low power consumption when displaying dark. So AMOLeds use less power in dark colors, have hundreds of times the contrast of traditional LCDS, and don"t leak light.AMOLED
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.
It comes with individual LEDs so, the pixels can be turned on and off individually. This will show you true black colours, as the pixels on the black part of the image will be turned off.
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.
The world of mobile display technology is divided between those who prefer AMOLED screens and those who prefer LCD screens. OLED technology, closely related to AMOLED displays, is available on specific mobile devices. Since the two are based on fundamentally different technologies, distinct manufacturers will promote different advantages for their chosen display technology, AMOLED or LCD. AMOLED displays are becoming the standard for smartphones, whereas LCD screens are often kept for budget models.
First, let’s talk about AMOLED, similar to OLED displays but has a few more bells and whistles. One must be familiar with each of its three parts to grasp it fully. LED, short for “Light Emitting Diode,” is the first. The “O” in OLED refers to “organic,” which describes the material used to construct the device.
To put it another way, each LED has two conductors in which organic material is inserted to assist generate light. And the “AM” in AMOLED stands for Active Matrix, which may improve a pixel’s quality. High brightness and sharpness, improved battery life, accurate colour reproduction, etc., are all features shared by the AMOLED and OLED displays. A capacitor connects each LED in an AMOLED display to a thin film transistor (TFT).
TFT is used to control each pixel in an AMOLED screen. There are probably many benefits to this presentation, but because there are also some drawbacks, I’ll mention them.
The benefits of using best AMOLEDscreen include a higher contrast ratio and more vibrant colours, which contribute to a more satisfying video-viewing experience. Individual pixels may be activated or deactivated thanks to the included LEDs. The pixels in the black area of the picture will be disabled, revealing the most accurate black possible.
LCD stands for “Liquid Crystal Display,” and its colour output differs from that of an AMOLED screen. Instead of employing separate LED lights for every pixel, an LCD screen has its own built-in backlight.
A backlight and colour filter are necessary components of every LCD panel, as we’ve discussed. A polarizer and a matrix of thin-film transistors are required stops for the backlight on its way to the display. This means that the whole screen will be illuminated, yet only a little amount of light will really reach the viewer. This is the main distinction between AMOLED and LCD, the two most common types of electronic displays now available.
Liquid crystal displays (LCDs) have lower production costs than AMOLEDs since they need less expensive light sources. LCD screens are also often seen in low-priced cell phones.
LCDs’ whites are so luminous because the backlight pumps so much illumination into each pixel that text on these screens can be read even in direct sunlight. Aside from that, it displays “Accurate True to Life” colours, which are most faithful to how things seem in the real world.
LCDs also provide the widest field of vision. This may be dependent on the kind of smartphone you use. However, most modern LCD screens have wide viewing angles with little colour shifting or distortion.
There are benefits and drawbacks to each of these presentation methods. Putting those aside, everything comes down to user choice, as different individuals have different tastes in colour schemes and contrast ratios. However, there are a few considerations that may aid you in selecting the one that is most suited to your needs.
Let’s talk about the cost to begin. The cost of a smartphone with an AMOLED screen is often higher than that of a smartphone with an LCD screen. This, is despite the fact that the tide is beginning to turn. Even still,thebest AMOLED screen of sufficient quality are now available on only the most expensive flagship handsets. AMOLED screens also provide very crisp and vivid colours. Additionally, they surpass the visual quality of any LCD screen. Compared to an LCD, an AMOLED screen isn’t nearly as bright. Therefore, an LCD screen performs much better when used in the open air.
Finally, we look at battery life, and no other display technology comes close to AMOLEDs in this regard. All modern smartphones include a “Dark Mode,” where the screen and app icons are black. There is no need for additional lighting while using this dark user interface, which is great for smartphones with AMOLED screens.
AMOLED screens are superior to LCD displays when compared using these criteria. In addition, major display original equipment manufacturers (OEMs) like Samsung and LG emphasise OLED technology for their next endeavours. Therefore, it is prudent to keep an eye out for AMOLED screens. However, if we witness more LCD technology improvements in battery economy and more, there is no need to cancel them at this time.
2) FPC interfaces include soldering, plug-in, and B2B connection, the reinforcement materials we commonly use include PI, PET, FR4, steel sheet, aluminum sheet, and so on, which can be selected according to different applications environments.

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.

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.

Is LCD or AMOLED better for eyes?The full English name of LCD is Liquid Crystal Display, which is a general term. According to its driving method, it can be divided into various specifications. Most monitors and laptops on the market today are thin-film transistors. Because TFT has better color saturation and viewing angles than other technologies, it is also the mainstream specification on the market today. The models on the market are mainly based on TFT, and LCD has now become synonymous with the term TFT display. Next, I will tell you in detail which LCD screen or OLED screen is better for the eyes.
Both OLED and LCD can cause damage to the eyes, because both OLED and LCD emit blue light, which is unavoidable. However, users can turn on the eye protection mode of the mobile phone to reduce the damage of blue light to the eyes. In addition, OLED"s dimming technology and LCD"s blue backlight are also one of the reasons for the "eye-hurt". OLED adopts PWM low-frequency dimming technology, which is a technology that adjusts the brightness through the rapid flickering of the light-emitting unit, so looking at the screen for a long time will cause eye fatigue. The blue backlight of an LCD monitor emits high-energy short-wave blue light.
In terms of manufacturing process, OLED adopts self-luminous technology and has no backlight layer, so this screen can be made very thin. In addition, each light-emitting unit of OLED can emit light independently when it emits light, and has the function of color screen display. LCD is composed of backlight layer, liquid crystal layer, color filter and other components, and the screen is made of inorganic materials, so the service life of this screen is relatively long.
Is LCD or AMOLED better for eyes?The above is the difference between lcd and oled. Users should try to avoid staring at the phone screen for a long time. Reduce LCD and AMOLED viewing time in dark environments. If you have the habit of reading late at night, you also need to turn on a light to neutralize the strobe light. Moisten your eyes with eye drops when your eyes are dry.
As with anything moving through the product lifecycle, once a product has shown its popularity, competitors move in to get a piece of the market, driving the price down making it more accessible. This trend will continue as we see the number of manufacturers who have the capability to produce AMOLEDs increase, along with better efficiency and volume shipments helping the end user, in particular, those who want to try a newer technology in an existing application or who are developing a brand new prototype.
When considering a digital display, a question of which technology to go with is always a common question. Whether you are an entrepreneur looking for a display solution or a manufacturer looking into new technologies, having access to AMOLED displays isn’t just for the big corporations with deep pockets.
When applied to the wearable market, AMOLEDs offer tremendous benefits. Smartwatches, for example, are a booming trend within this market. It is projected to globally “grow at a compound annual rate of 35% over the next five years, reaching 148 million units shipped annually in 2019” according to Business Insider. Furthermore, particular technological strides made by larger corporations have made it possible for smaller manufacturers to build on their R&D and success, causing the decreased cost in manufacturing, where AMOLEDs will be soon competitively priced with their LCD counterparts*.
When you look at the tech specs, AMOLED’s distinct advantage lies with its increased energy efficiency and thinner profile, applied to mobile and wearable applications. The idea behind this being that it requires no backlight like that of its LCD counterpart which consumes the majority of the energy allocated to the display. Another advantage is the presentation of true blacks. When the color black is depicted, rather than having a pixel illuminated, the pixel is absent of light. An excellent way to optimize energy consumption is to design a graphic user interface that uses black as a background.
From an industrial design standpoint, a significant advantage of an AMOLED is its narrow bezel. The bezel is the space between the active area and the outside dimension. For an AMOLED, the bezel size is less than that of alternative displays of similar size. A great advantage of having no backlight other than energy consumption is that it also creates a slimmer profile, freeing up space otherwise needed for the backlight and allows for a larger battery, makes it lighter, and could allow for extra room for other components. These are important variables when considering that the wearable industry is driving towards lighter, thinner, and sleeker looking products.
It’s no secret that Samsung tends to prefer AMOLED displays over TFT LCD, particularly on its higher-end smartphones and, more recently, on select high-end tablets. Outside of Samsung, we’ve seen other manufacturers turn to the technology as well, including Motorola with the Moto X.
The biggest advantage to AMOLED is that it provides more vibrant colors and blacker blacks, though the actual differences between the two technologies are a bit more complicated than that. Probably one of the biggest disadvantages is that AMOLED displays tend to be more expensive than LCD, simply because of production challenges that have kept AMOLED yields low.
Right now manufacturing prices of AMOLED displays are 10-20% more than comparable LCD panels, but the good news for AMOLED fans is that this situation may soon change. As production yields improve, NPD DisplaySearch claims that the costs of AMOLED displays could fall below than of LCD mobile phone displays within as little as two years.
[quote qtext=”Until recently there have been few breakthroughs in the production of AMOLED displays, and the OLED industry seemed to be facing hard times. If AMOLED costs fall below LCDs, as expected, it would lead to more opportunities for the OLED display industry, greater competition with LCD, and more choices for consumers. ” qperson=”Jimmy Kim” qsource=”DisplaySearch” qposition=”center”]
So what does this mean for the industry, and for consumers? As DisplaySearch puts it, for the OLED industry it means they will be able to better compete with LCD. Meanwhile the lowering of AMOLED costs could led more manufacturers to offer devices equipped with this alternative display technology, giving consumers even more options.
