In today’s technologically advanced world, we are surrounded by a wide variety of electronic devices, each of which has a unique display technology. Two of the more popular display technologies are TFT and AMOLED, and I’m going to take you to understand the difference between these two commonly used displays.
What is TFT
TFT stands for thin-film transistor, which is not a display technology in itself, but a very specific type of transistor used to improve image quality, and is most often used in conjunction with LCD displays.
TFT display technology employs a sandwich structure using liquid crystal material to fill the space between the two glass panels.TFT displays are made up of two polarization filters, a color filter, and two alignment layers that precisely determine the amount of light allowed to pass through and the colors produced.
What is AMOLED
AMOLED (Active Matrix Organic Light Emitting Diode) is a technology for OLED display devices.OLED display technology was invented with Steven Van Slyke and Jingwan Tang at Eastman Kodak in 1979, although the first OLED displays were used in car stereo screens, and it wasn’t until 2003 that the first consumer electronics products with full-color OLED displays were introduced.
AMOLED displays consist of OLED pixels and an active matrix, which is based on incoming signals from a control device, and each pixel is paired with a transistor that contains a capacitor; this allows each pixel to retain its charge, eliminating the need to send a charge again each time it is replaced, allowing for quick changes or refreshes, and these pixels, when electrically activated, produce cold light, which is deposited or integrated into the screen.
These pixels, when electrically activated, produce cold light that is deposited or integrated into an array of thin-film transistors; the array acts as a series of switches that control the current to each individual pixel.
Advantages of TFT Displays
The main advantage of TFT displays is their low production cost, which means that consumers can also enjoy the many options available at a low price.TFT displays have become a popular choice for entry-level smartphones and inexpensive televisions, and are widely available and compatible with a wide range of devices.TFT displays also offer good color reproduction and brightness levels, meeting many everyday needs.
Advantages of AMOLED displays
AMOLED displays are becoming increasingly popular in modern devices, most notably for their excellent color accuracy and contrast ratio.AMOLED display technology allows for vibrant colors and pure blacks to enhance the viewing experience. AMOLED displays adjust the brightness of each individual pixel, so unnecessary pixels can be lowered or switched off in darker areas, consuming less power.
AMOLED displays adjust the brightness of each individual pixel so that unnecessary pixels can be reduced or turned off in darker areas, consuming less power, and extending the battery life of smartphones and tablets.
Differences between TFT vs AMOLED displays
Light Source: The main difference between TFT and AMOLED displays is the way they emit light; TFT displays are illuminated by a backlight, while AMOLED displays are self-luminous.
Refresh rate: Refresh rate refers to the frequency of updates on the screen that produce different images per second. TFT displays have a refresh rate of about 50-60Hz, which is lower than the 144Hz refresh rate of AMOLED displays, which means that AMOLED displays have a more natural, responsive, and smoother display image than TFT displays.
Color Accuracy/Display Quality: TFT displays use a backlight to illuminate the pixels, resulting in colors that sometimes appear faded or less vibrant. AMOLED displays, on the other hand, are more accurate in displaying colors because each pixel of an AMOLED display emits its own light, meaning that colors are purer and more lifelike.
Viewing angle: Viewing angle is the angle at which we can see the display. tft display is the color change under extreme viewing angle, while AMOLED display is the all-around viewing angle. So AMOLED display has a wider viewing angle, we can view the screen from multiple angles and the color will not be distorted.
Energy Power Consumption: TFT display consumes less power than AMOLED display.The power consumption of AMOLED display depends on the brightness of the screen.Reducing the brightness of the screen can reduce the energy consumption, but it will also lead to a decrease in contrast.The backlight key of TFT display accounts for most of the power consumption.
The efficiency of the TFT screen will be greatly improved when the brightness of the backlight is set to a level lower than the default brightness.TFT screen is also more efficient than AMOLED display, so it is more efficient than AMOLED display.
Sunlight readable and ultra-white color: Since AMOLED displays need to be brighter under direct sunlight for the contrast to improve, TFT displays can easily achieve normal viewing of the display image content under sunlight by using high brightness backlighting, semi-transparent and semi-reflective displays, and so on.
In the pursuit of perfect ultra-white color, TFT display can be easily achieved by using white LED backlight; on the contrary, AMOLED display is difficult to achieve ultra-white color because the color is difficult to mix and looks a little yellow.
Availability: TFT displays are more widely available than AMOLED displays; TFT displays are commonly used in a wide range of devices because TFT displays are available in a variety of sizes and from a number of manufacturers, whereas AMOLED displays are more limited in terms of sizes and manufacturers, so TFT displays are more widely available.
Applications: Both TFT and AMOLED displays have a wide range of applications. TFT displays are commonly used in computer monitors, laptops, digital cameras, transportation, medical, watches, etc. as well as a wide range of consumer electronics, and the reliability and low cost of TFT displays make them suitable for a wide range of applications.
AMOLED displays bring unique advantages to industries such as high-end smartphones, high-end televisions and automobiles. AMOLED displays bring unique advantages to industries such as high-end smartphones, high-end TVs and automotive. The excellent visual quality and energy efficiency of AMOLED displays make them ideal for high-resolution and immersive applications.
Thickness and Durability: The durability of both TFT and AMOLED displays are presented in different ways. TFT displays control the illumination of the display by using thin-film transistors, which makes it heavier, thicker, and less flexible so it will be easier to be damaged when it is dropped and hit; TFT displays also have a fatal problem, which is that in case of individual pixel failures, it will stay in one color forever, and the overall color will appear.
AMOLED display is made of organic materials, making the display lighter, thinner and more flexible, which makes it resistant to drops and impacts; but also because it is made of organic materials, it will deteriorate over time, resulting in a decrease in the accuracy of color and brightness, which is often referred to as the “aging” phenomenon.
Cost of production: in terms of cost TFT displays are cheaper than AMOLED displays. amOLED displays use cutting-edge technology and help to reduce energy consumption, so it tends to be more expensive; and the intended use of AMOLED displays also affects its price. the price of both TFT displays and AMOLED displays goes up depending on the size of the screen and the resolution, as well as the price will be different for different brands.
TFT vs AMOLED display, which one is better for eyes?
Brightness and contrast: TFT display screen is too bright and contrast is too high, which will lead to eye fatigue easily, so we need to adjust the brightness to a comfortable level when using TFT display.
AMOLED display has a high contrast ratio, which means it can achieve deeper colors and can also display deeper blacks because each pixel of AMOLED display is self-luminous and can be completely turned off to display blacks to reduce eye fatigue.
Color Temperature: Color temperature is a measure of the warmth or coolness of light, usually expressed in Kelvin (K), color temperature is based on the frequency of blackbody radiation emitters have temperature. Distribution characteristics of the principle of light, the temperature below 4000K below the color looks reddish, while higher than 6000K above the color bluish.
AMOLED display adjustability makes the screen in different light conditions to find the right color temperature for viewing. And TFT display this can not be done. So, in the color temperature of this contrast AMOLED will be more good for the eyes.
Blue light: All digital screens emit blue light, which can cause more eye fatigue and disrupt sleep patterns if exposed to it for a long time. When blue light is emitted on both displays at the same time, AMOLED can adjust the brightness of individual pixels to maximize this feature, so the TFT display emits more harmful blue light than the AMOLED display.
Screen quality: a screen with higher resolution and color accuracy will be more friendly to our eyes. comparing TFT display with AMOLED display, AMOLED display can show more vivid and accurate colors. Therefore, AMOLED not only in the sense of viewing experience is greatly satisfied also can make the eyes more relaxed.
Taken together, all of these comparisons lead to the conclusion that AMOLED displays will cause less damage to our eyes than TFT displays. If you want to buy a display that is better for your eyes, you can consider LED display because it has more stable brightness, higher contrast ratio, wider color gamut, larger viewing angle and so on. However, no matter which screen type you choose, it’s important to maintain proper viewing distance and take regular breaks, among other eye care measures.
TFT vs AMOLED Display How should we choose?
In conclusion, both TFT and AMOLED displays have unique advantages and applications.TFT displays are more affordable and widely available, making them more suitable for budget-conscious consumers. On the other hand, AMOLED displays offer superior color accuracy, contrast, and less eye damage, making them ideal for high-end devices.
