1.7 Color Liquid Crystal Display
The color liquid crystal display (LCD) is composed of an LCD module, fluorescent lamps (FLs),
and an FL inverter board. The thin film transistor (TFT) LCD is illuminated from the back. Thus,
you can read its display clearly even in poorly lit conditions. It receives vertical and horizontal
synchronizing signals, 9-bit data signals, and shift clock signals for data transmission. All signals
are TTL-level compatible. The LCD specifications are described in Table 1-5.
The LCD has 512-color capability. The high frequency current is supplied by the FL inverter board
to illuminate the FLs. The color LCD is shown in Figure 1-7.
