HD66320T (TFT Driver)
(64-level Gray Scale Driver for
High-Quality TFT Liquid Crystal Display)
Preliminary
May 1995
The HD66320T, a source driver LSI, drives an active matrix LCD panel having TFTs (thin film
transistor) in the picture element (pixel) area. The LSI receives 6-bit digital display data per pixel and
outputs corresponding 64-level gray scale voltage. Since the output circuit on this LSI incorporates an
operational amplifier and has a wide dynamic range of 15V, a positive and a negative voltage can be
alternately output to each output pin. Therefore, a high-quality display can be achieved without a
complex circuit configuration. This LSI is suitable for a VGA-or SVGA-sized color TFT LCD.
Features
High-speed operation
Maximum operating clock: 45MHz (5/3.3V)
Logic operating voltage
VCDD = 2.7 to 5.5V
LCD drive voltage
High voltage: V
EE
= 15V
Low voltage: V
CCA
= 5V
240 LCD drive circuit
Multicolor display
The HD66320T receives 6-bit digital display data per pixel, and selects and outputs an LCD drive
voltage among 64-level gray scale voltages. When R, G, and B color filters are added to the LCD
panel, a maximum of 260 thousand colors can be displayed.
Low output voltage deviation
Voff = ±10 mV (MAX)
No external reference voltage generator required
Bidirectional shift
Chip enable signal generator
Package
Slim-type TCP
