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 • Output dynamic range : VSS2+0.1 V to VDD2−0.1 V

5 • Logic part supply voltage (VDD1) : 3.3 V ± 0.3 V

5 • 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).
