UPD16633B - 312 OUTPUT TFT-LCD SORCE DRIVER

General Description

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

The display data is input with a width of 36 bits, viz., the gray scale data (6 bits) by 6 dots (2 pixels).

Key Features

  • Capable of outputting 64 values by means of 5-by-2 external power modules (10 units) and a D/A converter.
  • Output dynamic range 9.8 VP-P min. (@VDD2 = 10.0 V).
  • CMOS level input.
  • Input of 6 bits (gradation data) by 6 dots.
  • High-speed data transfer: fmax. = 45 MHz (internal data transfer speed when operating at 3.0 V).
  • 312 outputs.
  • Apply for only dot inversion.
  • Display data inversion function (POL2 terminal. ).
  • Single.

DATA SHEET MOS INTEGRATED CIRCUIT µPD16633B 312 OUTPUT TFT-LCD SORCE DRIVER (COMPATIBLE WITH 64 GRAY SCALES) The µPD16633B 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 9.8 VP-P, level inversion operation of the LCD’s common electrode is rendered unnecessary.
