Overview
DATA SHEET MOS INTEGRATED CIRCUIT µ PD16772 480-OUTPUT TFT-LCD SOURCE DRIVER (COMPATIBLE WITH 64-GRAY SCALES) DESCRIPTION The µ PD16772 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, 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 UXGA-standard TFT-LCD panels.
FEATURES • CMOS level input (2.
3 to 3.
6 V) • 480 outputs • 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 (RDAC) • Output dynamic range : VSS2 + 0.
1 V to VDD2 – 0.
1 V • High-speed data transfer : fCLK = 45 MHz (internal data transfer speed when operating at VDD1 = 2.
3 V) • Apply for dot-line inversion, n-line inversion and column line inversion • Output voltage polarity inversion function (POL) • Display data inversion function (POL21/22) • Current consumption reduction function (LPC, Bcont) • Logic power supply voltage (VDD1) : 2.
3 to 3.
6 V • Driver power supply voltage (VDD2) : 8.
5 V ± 0.
