HD66324T (TFT Driver)
64-level Grayscale Driver for the High-Quality TFT
Liquid Crystal Display for XGA/SXGA Systems
Rev.0.0
September 1997
Description
The HD66324T is a TFT-LCD source driver LSI suitable for XGA and SXGA systems. It receives 6-bit-
per-pixel digital display data, and generates and outputs voltages for 64 grayscales. The output circuit
includes an operational amplifier, and is capable of alternate output of positive-polarity and negative-
polarity voltages on individual output pins. This makes it possible to achieve a high-quality display with
little crosstalk without the use of complex power supply circuitry.

Multicolor display
The HD66324T receives 6-bit-per-pixel digital display data, and selects and outputs a display
voltage from 64 grayscale voltages, enabling a maximum of 260,000 display colors when using
R/G/B color filters.

High-voltage asymmetric drive
With a wide dynamic range of 10.8 V, and the ability to output positive-polarity and negative-
polarity voltages, it is not necessary to provide a counter-electrode alternating current. Also, since
both positive-polarity and negative-polarity voltages are generated by an externally provided
reference power supply, either an asymmetric or a symmetric drive can be used according to the
characteristics of the liquid crystal.
