General Description

The µ PD16718 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 7-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.

Key Features

  • CMOS level input (2.5 to 3.6 V).
  • 480/420 Outputs.
  • Input of 6 bits (gray scale data) by 6 dots.
  • Capable of outputting 64 values by means of 7-by-2 external power modules (14 units) and a D/A converter (R- DAC).
  • Logic power supply voltage (VDD1): 2.5 to 3.6 V.
  • Driver power supply voltage (VDD2): 10.0 to 12.5 V.
  • Output dynamic range VSS2 + 0.1 V to VDD2.
  • 0.1 V.
  • High-speed data transfer: fCLK = 57 MHz (internal data tr.
