DESCRIPTION

The

µ PD16732A, 16732B are 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.

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 maximum clock frequency of 65 MHz when driving at 3.0 V, 45 MHz when driving at 2.3 V, this driver is

applicable to XGA-standard TFT-LCD panels and SXGA TFT-LCD panels by input display signal 2 systems (Clock

divide).
