uPD16740 - 384-OUTPUT TFT-LCD SOURCE DRIVER

Datasheet Summary

Description

The D/A converted 64/256-gray-scale analog voltage is output.

The display data is input in either a 48-bit width of 8-bit gray-scale data × 6 dots (2 pixels) or in a 36-bit width of 6-bit gray-scale data × 6 dots (2 pixels).

Features

  • CMOS level input.
  • 384-output channel.
  • Input of 8 bits (gradation data) by 6 dots.
  • Capable of outputting 256 values by means of 11 external power modules and a D/A converter (C-DAC).
  • Logic Part Power Supply Voltage (VDD1) : 3.3 ± 0.3 V.
  • Driver Part Power Supply Voltage (VDD2) : 8.5 ± 0.5 V.
  • High-speed data transfer: fMAX. = 40 MHz (internal data transfer speed when operating at VDD1 = 3.0 V).
  • Output dynamic range VSS2 + 0.1.

DATA SHEET MOS INTEGRATED CIRCUIT µ PD16740 384-OUTPUT TFT-LCD SOURCE DRIVER (COMPATIBLE 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 11 external power modules. Because the output dynamic range is as large as VSS2 + 0.1 V to Vref – 0.1 V, level inversion operation of the LCD’s common electrode is rendered unnecessary.
