To all our customers
Information regarding change of names mentioned
within this document, to Renesas Technology Corp.
On April 1st 2003 the following semiconductor operations were transferred to
Renesas Technology Corporation: operations covering microcomputer, logic,
manalog and discrete devices, and memory chips other than DRAMs (flash
memory, SRAMs etc.).
oAccordingly, although Hitachi, Hitachi, Ltd., Hitachi Semiconductors, and other
.cHitachi brand names are mentioned in the document, these names have all
been changed to Renesas Technology Corporation.
Except for our corporate trademark, logo and corporate statement, no
Uchanges whatsoever have been made to the contents of the document, and

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 on-
chip 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, comb type)
• Mode setting
Serial transfer from the HD66770/772 source driver
• Power-supply voltage
Logic power supply: Vcc - GND = 1.8 to 3.3 V
Power supply for a gate-line driving circuit: VGH – VGL = 18 to 33 V (GND reference
voltage: ±9 to ±16.5 V)
Power supply for driving a gate line: VGH – GND = 9 to 16.5 V, and Vgoff – GND = -5 to
–16.5 V
• Power-supply circuit
Each power-supply voltage is supplied from the HD667P00 power-supply IC chip.
