HD66775 Datasheet | Hitachi Semiconductor

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. 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, b type) - Mode setting  Serial transfer from the HD66770/772 source driver -...
