420-OUTPUT TFT-LCD SOURCE DRIVER
(COMPATIBLE WITH 64-GRAY SCALES)
DESCRIPTION
The
碌
PD16770B 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
緯
-corrected by an internal D/A converter and 5-by-2 external power modules.
Because the output dynamic range is as large as V
SS2
+ 0.1 V to V
DD2
鈥?0.1 V, level inversion operation of the LCD鈥檚
common electrode is rendered unnecessary. Also, to be able to deal with dot-line inversion, n-line inversion and
column 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 clock frequency of 45 MHz when driving at 2.3 V, this driver is applicable to SXGA + standard TFT-LCD
panels.
