The backlight module is needed for the light behind the screen that illuminates the screen and the LCD can't emit light by itself. Nowadays, the screen materials of mobile phones are mainly divided into TFT, led and LCD. The TFT and LCD screens all need backlight, because their LCD materials can't emit light, so the screen is thicker, and the effect in the sun is not very good, and it costs more electricity, but the technology price is lower. And the LED itself has a self luminous liquid crystal, so the screen is relatively thin, the effect of the sun is better, save electricity.
