300-OUTPUT TFT-LCD SOURCE DRIVER
(COMPATIBLE WITH 64 GRAY SCALE)
DESCRIPTION
The µPD16634A is a source driver for TFT-LCDs capable of dealing with displays 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
5 ^{output dynamic range is as large as VSS2+0.1 V to VDD2−0.1 V, 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 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 frequent of 40 MHz when
drivng at 3.0 V, this driver is applicable to XGA-standard TFT-LCD panels.
FEATURES
• 300 outputs
• CMOS level input
