UPD16772A - 480-OUTPUT TFT-LCD SOURCE DRIVER

Datasheet Summary

Description

The µ PD16772A is a source driver for TFT-LCDs capable of dealing with displays with 64-gray scales.

Features

  • CMOS level input (2.3 to 3.6 V).
  • 480 outputs.
  • Input of 6 bits (gradation data) by 6 dots.
  • Capable of outputting 64 values by means of 5-by-2 external power modules (10 units) and a D/A converter (RDAC).
  • Output dynamic range : VSS2 + 0.1 V to VDD2.
  • 0.1 V.
  • High-speed data transfer : fCLK = 45 MHz (internal data transfer speed when operating at VDD1 = 2.3 V).
  • Apply for dot-line inversion, n-line inversion and column line inver.

DATA SHEET MOS INTEGRATED CIRCUIT µ PD16772A 480-OUTPUT TFT-LCD SOURCE DRIVER (COMPATIBLE WITH 64-GRAY SCALES) DESCRIPTION The µ PD16772A is 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. 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.
