SSD2131

简介

The SSD2131 is a single chip, RAM-less solution for LTPS TFT LCD that incorporates gate drivers, a timing controller with glass interface level shifters, a VCOM driver and a glass power supply circuit.  The SSD2131 supports MIPI interface. The source resolution support 1080RGB, and the gate resolution can also be set 1920 lines and 2160 lines.

The SSD2131 is also able to make gamma correction settings separately for RGB dots to allow benign adjustments to panel characteristics, resulting in higher display qualities. The IC includes internal boosters that generate the LCD driving voltage, breeder resistance and voltage follower circuit for the LCD driver. At deep standby mode, it also supports lower power consumption.
