DESCRIPTION

The µ PD160062 is a source driver for TFT-LCDs capable of dealing with displays with 64-gray scale. 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 SXGA+ standard TFT-LCD panels.
