Description

The PD16640C is a source driver for TFT-LCD 64-gray scale displays. Its logic circuit operates at 3.3 V and the driver circuit operates at 3.3 or 5.0 V (selectable). The input data is digital data at 6 bits x 3 dots, and 260,000 colors can be displayed in 64-value outputs g-corrected by the internal D/A converter and 11 external power supplies.

The clock frequency is 55 MHz MIN. By switching over the number of outputs between 300 and 309, the PD16640C can be used in TFT-LCD panels conforming to the SVGA/XGA standards.
