240RGB x 320 TFT LCD Driver
Integrated Power Circuit, Source and Gate Driver Circuits

SSD1269 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.

SSD1269 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.

SSD1269 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.
