LCD stands for liquid crystal display, is now used more in mobile phone screen materials. It is characterized by low price, widespread use, and the need for backlight support when displaying.
The most common LCD display technology in mobile phone screen mainly includes: TFT, IPS, SLCD and other screen materials.
The LCD display is composed of a backlight, a lower polarizer, a driving layer, a liquid crystal layer, a color filter and an upper polarizer. The driving layer is composed of thin film transistors.

TFT is thin film field effect transistor, which belongs to active matrix liquid crystal display.
TFT LCD screen is characterized by good brightness, high contrast, strong sense of layer, bright color. But there is also a relatively high power consumption and cost of insufficient.

IPS, commonly known as "Super TFT", is a technology upgraded from TFT. In essence, it is a TFT screen using IPS technology. Compared with the ordinary TFT screen, it has the advantages of large viewing Angle, accurate color restoration, no water lines, environmental protection and power saving.

SLCD is a special splicing LCD screen, a high-end advanced variety of LCD, characterized by warmer color, true, more natural, and suitable for human eyes.

OLED stands for organic light-emitting diode. OLED has the advantages of self-luminous, wide viewing angle, high contrast, low power consumption, high reaction rate, full color, simple process and so on.

According to the driving mode, OLED can be divided into passive OLED (PMOLED) and active OLED (AMOLED).
AMOLED screens have the advantages of flexibility, wide color gamut, and low power consumption.
