UPD16449
DESCRIPTION
µPD16449 is a source driver for TFT liquid crystal panels. This IC consists of a multiplexer circuit supporting a
..variety of pixel arrays, a shift register that generates sampling timing, and two sample and hold circuits that sample analog voltages. Because the two sample and hold circuits alternately execute sampling and holding, a high definition can be obtained. In addition, simultaneous sampling and successive sampling are automatically selected according to the pixel array of the LCD panel. It is ideal for a wide range of applications, including navigation systems and automobile LCD-TVs.
