480 x 272RGB TFT LCD Driver


Integrated Power Circuit, Gate and Source Driver
 

 

SSD2128M1ZC is an all in one driver that integrated the power circuits, gate driver and source driver into single chip.  It can drive a 16.7M/262k a-TFT panel with resolution of 480 x 272 RGB.


SSD2128M1ZC 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.  The driver supports three separated RGB Gamma settings. An Integrated Gamma Control Circuit is also included that can be adjusted by software commands to provide maximum flexibility and optimal display quality.


SSD2128M1ZC can be operated down to 2.5V (VCI) and provide different power save modes.  It is suitable for any portable battery-driven applications requiring long operation period with compact size.
