Block Diagram of the LCD Module
24-bit color or 3-LVDS channels can be used for 18-bit color. routed to the 8-6 bit translator. Spectrum methods supported are Center and Down Spread. plexed dithering technique or simple truncation of the LSBs. This function is enabled via the input control pins. characteristics such as trace impedance, termination, etc. FIGURE 2. Block Diagram
