Overview
DATA SHEET MOS INTEGRATED CIRCUIT µPD16634A 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 • Input of 6 bits (gradation data) by 6 dots • Capable of outputting 64 values by means of 5-by-2 external power modules (10 units) and a D/A converter 5 5 5 • Output dynamic range : VSS2+0.
1 V to VDD2−0.
1 V • Logic part supply voltage (VDD1) : 3.
3 V ± 0.
3 V • Driver part supply voltage (VDD2) : 8.
0 V ± 0.
5 V • High-speed data transfer: fMAX=40 MHz MIN.
(internal data transfer rate when operating at 3.
0 V) • Output voltage polarity inversion is possible (POL) • Display data inversion function (POL2) • Single bank arrangement is possible(loaded with slim TCP).
