System Overview
The following shows a block diagram of a TFT color LCD system configured with multiple HD66330Ts.
The HD66330Ts latch 6-bit data per dot, and selects and outputs one level among 64 internally generated
LCD drive voltage levels. When the pixels are structured using R, G, and B color filters, a maximum of
260,000 colors can be displayed.
