HD66775 - 120-Channel Gate Driver

Description

HD66775 is a gate-driver IC for systems with color-TFT-liquid-crystal dot-matrix graphic displays.

It incorporates a circuit for driving 120 channels of TFT gate lines, and realizes the liquid crystal display.

Features

  • TFT gate-line driving circuits  120 outputs: can be expanded to 240 channels with the master/slave function (two HD66775s are used).
  • Gate-line scanning  Centering-screen function (vertically separated, comb type).
  • Mode setting  Serial transfer from the HD66770/772 source driver.
  • Power-s.

—PRELIMINARY— HD66775 120-Channel Gate Driver for Color-TFT Liquid Crystal Displays Rev.0.3 September 2001 Description HD66775 is a gate-driver IC for systems with color-TFT-liquid-crystal dot-matrix graphic displays. It incorporates a circuit for driving 120 channels of TFT gate lines, and realizes the liquid crystal display. When two HD66775s are used with the HD66770 396-channel source driver with on-chip RAM and the HD667P00 power-supply IC chip, and used with the HD66772 528-channel source driver with onchip RAM and the HD667P00 power-supply IC chip, this LSI is suitable for color TFT displays of cellular phones having 132-by-176 and 176-by-240 dots, respectively.
