Regarding mobile phone screens, we often hear full screens, waterfall screens, etc. In fact, these are just the display form of the screen. In the final analysis, the common mobile phone screens on the market are mainly LCD screens and OLED screens.

Because LCD has a backlight layer, it emits light by refracting light, the color saturation is not so high, and the display effect is more natural.

With the continuous advancement of technology, new breakthroughs have been made in the materials used to make screens. There are two main types of mobile phone screens on the market today: OLED screens and LCD screens. Let's take a look at the origin of these two materials!

First, the OLED screen is a self-illuminating display mechanism. Therefore, OLED can achieve screen-off display.

The materials constituting OLED are mainly organic substances, which can be divided according to the types of organic substances, one is small molecule and the other is macromolecule.
