Advance Information 240 RGB x 320 TFT LCD Driver 

Integrated Power Circuit, Source and Gate Driver, Build-in RAM, and Content Adaptive Brightness Control (CABC)

SSD1268 is an all in one TFT LCD Driver that integrated the power circuits, gate driver and source driver into a single chip. It can drive up to 262k color amorphous TFT panel with resolution of 240 RGB x 320.

It also integrated the controller function and consists of up to 172,800 bytes (320 x 240 x 18 / 8) Graphic Display Data RAM (GDDRAM) such that it interfaced with common MCU through 8/9/16/18-bits 6800-series / 8080-series compatible Parallel Interface or Serial Interface and stored the data in the GDDRAM.Auxiliary 18-/16- bit video interface (VSYNC, HSYNC, DOTCLK, and ENABLE) are integrated into SSD1268 for animation image display. SSD1268 embeds DC-DC Converter and Voltage generator to provide all necessary voltage required by the driver with minimum external components. A Common Voltage Generation Circuit is included to drive the TFT-display counter electrode. An Integrated Gamma Control Circuit is also included that can be adjusted by software commands to provide maximum flexibility and optimal display quality. SSD1268 can be operated down to 1.4V and provide different power save modes. It is suitable for any portable battery-driven applications requiring long operation period and compact size.
