384-OUTPUT TFT-LCD SOURCE DRIVER
(COMPATIBLE WITH 64-GRAY SCALES)
DESCRIPTION
The µPD16715A 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 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 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 55 MHz when
driving at 3.0 V, this driver is applicable to XGA/SXGA-standard TFT-LCD panels.
