DATA SHEET MOS INTEGRATED CIRCUIT µPD16634A 300-OUTPUT TFT-LCD SOURCE DRIVER (PATIBLE 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 mon 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: f MAX=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).
