Renesas Technology Corp. has announced the release of the HD66782 single-chip TFT color liquid crystal panel driver that supports 132 x 132 pixels and 260K color display. Suitable for mobile phone applications, the product achieves low power consumption that is identical to that of STN color liquid crystal panels. Power consumption for 260K color normal display, including the panel, is approximately 2mW, while the use of power-down functions such as an 8-color mode and standby modes allows power consumption to be further reduced to approximately 0.8mW.

The provision of an on-chip power supply allows single-chip liquid crystal panel drive, reducing the number of component parts required, and the provision of a high-speed moving image interface allowing direct reception of RGB signals from an MPEG-4 or similar graphics processing LSIs enables smooth moving image display to be achieved. Connection to a microcomputer is via an 8/9/16/18-bit high-speed bus interface.

Outputs are 396 (source) and 132 (gate), display RAM capacity is 39,204 bytes, and voltages are 2.4V to 3.3V (logic power supply), 1.65V to 3.3V (interface I/O), and 4.5V to 5.5V (liquid crystal drive).
