1.6 Sidelit Liquid Crystal Display
The sidelit Liquid Crystal Display (LCD) is composed of an LCD module, a Fluorescent Lamp
(FL), and an FL inverter board.
1.6.1
LCD Module
The T2200SX sidelit LCD is illuminated from the side and supports 640x480 pixels with a High
Resolution Graphics Subsystem (HRGS) and 16 levels of gray. The HRGS includes the functions of
the Video Graphics Array (VGA).
The LCD receives vertical and horizontal synchronizing signals, 8-bit data signals (4-bit upper data
signal, 4-bit lower data signal), and shift clock for data transmission from the PVGA1F video
controller. All signals are CMOS-level compatible.
The sidelit LCD is shown in Figure 1-7 and its specifications are described in Table 1-3.
