UPD16634A Overview
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...
