TFT vs OLED screens

What is a TFT Display?

A TFT display is a form of Liquid Crystal Display with thin-film transistors for controlling image formation. The 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.

What is an OLED Display?

This type of display requires no backlight and can light up or turn off each of their pixels independently, meaning they offer better contrast and color.

What is the difference between OLED and TFT LCD?

1 / LCD is achieved by the emitting light of Liquid Crystal, while the OLED can emit light once it is electrified. So the main difference is that TFT screen needs to use a backlight to illuminate the screen, while OLED can produce light by itself.

2/ Compared with the TFT screen, OLED doesn’t need external light, so it can reduce the number of materials, the structure of OLED display is more simple, light, and power-saving.

3/ Compare from the front of the pure black wallpaper, OLED is pure black while TFT is not because of its backlight.

4/ Compare on the rear, from the back edge, OLED has no backlight bleed-through while TFT has.

5/OLEDs don’t always function as well as TFT when it comes to power consumption. If the content on the display is rich, it will drain their battery faster than it would on a TFT screen.

6/ Due to the extremely clean environment required, a single point of dust may damage the display during the OLED  manufacturing process.

Conclusion:

TFT technology has matured and the market supply is relatively stable; Prices are very competitive, available in a wide range of sizes and different quality levels. Actually, a superior version of the TFT can provide all-around viewing angles and exceptional contrast ratio, just comes at a premium cost compared to standard TFT models, regarding the superior version of the TFT get to know more about D-4 Screen.

OLED Technology very slim profile display; No backlight means less power consumption; Bright and vibrant colors and all-round viewing angles; Displays look black when switched off;  more expensive to produce than TFT and OLED panels are affected by the presence of water, and Shorter lifespan than TFT as well.
