System Overview
The following shows a block diagram of an SVGA (800
×
600)-applicable TFT color panel configured
with multiple HD66320Ts. These HD66320Ts latch 6-bit data per dot, and select and output one level
among 64 internally-generated LCD-drive voltage levels of positive or negative polarity. When the pixels
are structured using R, G, and B color filters, a maximum of 260 thousand colors can be displayed. In
addition, the inversion drive for each row or for each dot can be achieved even though the HD66320Ts
are located on one side as long as the inversion output function for each pin is used; this achieves a high-
quality display.
