The basic knowledge of OLED and LCD
Here, we will not specifically introduce the technical principle of LCD and OLED. You just need to remember that LCD (Liquid Crystal Display) is achieved by the emitting light of Liquid Crystal, while the OLED (Organic Light - Emitting Diode) can emit light once it is electrified.
So the main difference is that the LCD needs to use a backlight to illuminate the screen, while OLED can produce light by itself.
Compared with LCD display, OLED don’t need external light, so it can reduce the number of CCFL backlight module, and also the TFT glass, C/F glass and a set of 0 polaroid. Thanks to these features, the structure of OLED display is more simple, light, and power-saving.
In the full-screen era, OLED displays are more popular. And it also has something to do with the fingerprint recognition technology. For this technology need to penetrate the display, so the thinner display, the better it is. That’s why the OLED display is preferred. In a word, the OLED display is more suitable for smartphones.
