System Overview
Figure 3 is a block diagram of the configuration of an XGA (1024
×
768) compatible TFT color panel
with the HD66325As. The HD66325A latches 6-bit data for each dot, selects a level from the 64
positive-polarity or negative-polarity liquid-crystal application voltages generated internally, and
outputs that voltage.
By configuring pixels using R/G/B color filters, a full-color display of approximately 260,000 colors
can be achieved. In addition, use of the pin-by-pin output inversion function allows row-by-row
inversion drive and dot-by-dot inversion drive even with a single-sided HD66325A arrangement,
enabling a high-quality display.
