uPD16740 Description
DATA SHEET MOS INTEGRATED CIRCUIT µ PD16740 384-OUTPUT TFT-LCD SOURCE DRIVER (PATIBLE WITH 256-GRAY SCALES) The µ PD16740 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 16,700,000 colors by output of 256 values γ -corrected by an internal D/A converter and...
