PRELIMINARY PRODUCT INFORMATION
MOS INTEGRATED CIRCUIT
µPD160083
480-OUTPUT TFT-LCD SOURCE DRIVER
(COMPATIBLE WITH 256-GRAY SCALES)
DESCRIPTION
The µ PD160083 is a source driver for TFT-LCDs capable of dealing with displays with 256-gray scales. Data input
is based on digital input configured as 8 bits by 3 dots (1 pixel) with double clock edge, which can realize a full-color
display of 16,777,216 colors by output of 256 values γ -corrected by an internal D/A converter and 9-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,
n-line inversion and column line inversion when mounted on a single side, this source driver is equipped with a built-
in 8-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 85 MHz when driving at 3.0 V, this driver is applicable to UXGA-
standard (1600Ê·1200), SXGA-standard (1280Ê·1024) TFT-LCD panels.
FEATURES
• RSDS^TM (Reduced Swing Differential Signaling) interface
• 480 outputs
• Input of 8 bits (gradation data) by 3 dots with double clock edge sampling
• Capable of outputting 256 values by means of 9-by-2 external power modules (18 units) and a D/A converter
• Logic power supply voltage (VDD1): 2.7 to 3.6 V
