TFT LCD VS AMOLED: How to choose



As technology continuously evolves, so do our devices. One of the most significant advancements in smartphones and other electronic devices is the screen display. Two of the most common display technologies are thin-film transistor (TFT LCD) and active-matrix organic light-emitting diode (AM-OLED). In this article, we will take a comprehensive look at TFT LCD vs AMOLED displays, including their pros and cons, display quality, power consumption, price, and their performance in industrial applications.

What is TFT display technology?

As mentioned earlier, TFT is a type of LCD technology that uses thin-film transistors to control the amount of light that passes through each pixel. TFT displays are made up of several layers, including a backlight, color filter, and liquid crystal layer. The transistors on the TFT layer help to regulate the voltage applied to each pixel, allowing the display to produce accurate and consistent colors.

TFT displays have several advantages, including high resolution, fast response time, and a wide viewing angle. They are also more affordable than other types of display technologies. However, TFT displays have a few drawbacks, such as limited color gamut, poor contrast ratio, and low power efficiency.

What is AMOLED display technology?

AMOLED display technology is an advanced display technology that uses organic compounds to produce light when an electric current is applied. The organic compounds are arranged in a thin film, and when an electric current passes through them, they emit light. AM-OLED displays do not require a backlight, as each pixel can produce its own light.

AMOLED displays have several advantages, including high contrast ratio, vivid colors, and energy efficiency. They also have a wide viewing angle and are known for their deep blacks. However, AMOLED displays are expensive to produce and are prone to burn-in, which can cause permanent damage to the screen.


Both TFT and AMOLED displays have their strengths and weaknesses. TFT displays have a high resolution and fast response time, making them ideal for industrial devices. However, they have a limited color gamut and poor contrast ratio compared to AM-OLED displays. On the other hand, AM-OLED displays have a high contrast ratio and vivid colors, making them ideal for displaying images and videos. However, they are prone to burn-in, which can cause permanent damage to the screen.

Power consumption comparison

AMOLED displays have an advantage over TFT displays. As mentioned earlier, AM-OLED displays do not require a backlight, which helps to conserve energy. Additionally, AMOLED displays can turn off individual pixels, resulting in even more energy savings. In contrast, TFT displays require a backlight, which can consume a significant amount of energy.

Price comparison

TFT displays are generally more affordable than AMOLED displays. This is because TFT displays are easier and cheaper to produce. However, as technology advances, the price gap between the two display technologies is closing.

Which one is better for industrial applications?

TFT displays have an advantage over AMOLED displays. TFT displays have a wide range size and resolution for choose. Additionally, TFT LCD is more cost-effective, which can help to reduce project budget. On the other hand, AMOLED displays have a higher contrast ratio and more vivid colors, they were most installed in smartwatch, mobilephone, and high end monitor.

Future of TFT LCD and AMOLED display technology

As technology continues to evolve, it is likely that both TFT and AMOLED display technologies will continue to improve. TFT displays may become more energy-efficient and have a wider color gamut. AMOLED displays may become less prone to burn-in and more affordable to produce.


In conclusion, TFT LCD and AMOLED displays are two popular display technologies used in electronic devices. Both have their strengths and weaknesses, and the choice between the two depends on the intended use of the device. TFT displays are ideal for industrial and are more affordable, while AMOLED displays are ideal for displaying images and videos and have a higher contrast ratio. As technology continues to evolve, both display technologies are likely to continue to improve.
