What are the main differences, advantages and classifications between AMOLED and TFTLCD screens?
Main differences:
- Light-emitting principle: AMOLED is self-luminous, and displays different colors through different RGB light-emitting body display combinations. The TFT screen emits light through the backlight unit, turns it on and off through the liquid crystal control, and then displays different colors through different RGB color filters.
- Thickness: Due to the different light-emitting methods, TFT-LCD requires a backlight, so the overall thickness is thicker than AMOLED.
- Color and contrast: AMOLED screens are more colorful, diverse, and have higher contrast. Although TFT screens are also colorful, they are slightly inferior in comparison.
Power consumption and life: TFT screens are relatively more power-consuming, while AMOLED screens are relatively power-saving and suitable for portable devices. However, the life of AMOLED is relatively short and is easily affected by environmental factors. Main advantages: AMOLED screens have obvious advantages over TFT-LED screens.
AMOLED screens use active light-emitting technology. In addition to displaying colors, each pixel also has self-luminous properties, which means that in a pure black background, non-luminous pixels will not waste electricity, thus saving power. In addition, AMOLED screens are more vivid in color, although this vividness may take some time to adapt, because people may feel that AMOLED is reddish when they first see it after being accustomed to the white TFT screen, but after adapting, they will find that AMOLED has obvious advantages in color.
However, a major disadvantage of AMOLED screens is that they do not perform well in high-brightness environments, and their relatively high cost limits their widespread application to a certain extent.
In contrast, although TFT-LED screens are mature in technology, low in cost, their color performance and power consumption are not as good as AMOLED. AMOLED’s advantages lie in its excellent color performance, low power consumption, fast response time, and thin and light design, which make it more likely to become mainstream in future display technologies12.
In summary, although TFT-LED screens are widely used due to their low cost and mature technology, AMOLED’s advantages in color, power consumption and thin design make it a better choice, especially in the high-end smartphone market, where AMOLED screens are more widely used.
Main categories:
OLED is mainly classified according to display color: AMOLED and PMOLED
