PD16449
SOURCE DRIVER FOR 240-OUTPUT TFT-LCD
(NAVIGATION, AUTOMOBILE LCD-TV)
DESCRIPTION
碌
PD16449 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.
