简介
The SSD2068 is a TDDI (Touch and Display Driver Integration) IC integrating touch sensing and display driving schemes supporting FWVGA TFT LCD displays (480RGB x 854). SSD2068 supports 1440 source output plus high voltage gate control signal for GIP designs.
Supporting MIPI serial interface, SSD2068 is embedded with DC-DC Converter and Voltage Regulator to generate the voltage level necessary for the TFT panel, with minimum number of external components required. The SSD2068 includes touch channels for In-Cell panels. It supports a maximum of 400 self-capacitive nodes plus 8 touch keys.
