DATA SHEET MOS INTEGRATED CIRCUIT µ PD16750 384-OUTPUT TFT-LCD SOURCE DRIVER (COMPATIBLE WITH 256-GRAY SCALES) DESCRIPTION The µ PD16750 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 6 dots (2 pixels), 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 8-by-2 external power modules. Because the output dynamic range is as large as VDD2 − 0.2 V to VSS2 + 0.2 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 maximum clock frequency of 40 MHz when driving at 3.0 V, this driver is applicable to XGA-standard TFTLCD panels and SXGA TFT-LCD panels. This driver is applicable to SXGA TFT-LCD panels by input display signal 2 systems (Clock divide).
