MOS INTEGRATED CIRCUIT

µPD16636

312 OUTPUT TFT-LCD SOURCE DRIVER

(COMPATIBLE WITH 64 GRAY SCALES)

The

µPD16636 is a source driver for TFT-LCDs capable of dealing with displays with 64 gray scales. Data input

is based on digital input configured as 6 bits by 6 dots (2 pixels), which can realize a full-color display of 260,000 colors

by output of 64 values

γ -corrected by an internal D/A converter and 5-by-2 external power modules. Because the

output dynamic range is as large as 9.6 VP-P, level inversion operation of the LCD’s common electrode is rendered

unnecessary. Also, to be able to deal with dot-line inversion when mounted on a single side, this source driver is

equipped with a built-in 6-bit D/A converter circuit whose odd output pins and even output pins respectively output

gray scale voltages of differing polarity. Assuring a maximum clock frequency of 45 MHz when driving at 3.0 V, this

driver is applicable to XGA-standard TFT-LCD panels.
