Classification

According to the material of the screen, the mainstream screens of smartphones can be divided into two categories, one is LCD (abbreviation of Liquid Crystal Display), that is, liquid crystal displays, such as TFT and SLCD screens.

The other is OLED (Organic Light-Emitting Diode), that is, organic light-emitting diodes, such as AMOLED series screens. The most fundamental difference between LCD and OLED is that OLED is self-illuminating, while LCD needs to be illuminated by a backlight plate to display.

According to the display technology driving mode of the screen, it can be divided into two categories: passive matrix and active matrix. The difference between passive matrices and active matrices is the way the current is driven.

When the external current passes, the arrangement of the liquid crystal will change, and after the current stops, if the liquid crystal arrangement remains in place (with memory), it is called the active matrix; Once the current disappears, it returns to its original position and must be charged again to be arranged, which is called a passive matrix.
