2. Overview This module is a color active matrix LCD module incorporating amorphous silicon TFT (Thin Film Transistor). It is composed of a color TFT-LCD panel, driver ICs, control circuit, power supply circuit and a backlight unit. Graphics and texts can be displayed on a 800 X 3 X 600 dots panel with 262,144 colors by using LVDS (Low Voltage Differential Signaling) system for interface and supplying +3.3Vor+5.0V DC supply voltage for TFT-LCD panel driving. This module is super-high brightness (450cd/m^2) and high contrast (600:1). This module is the type of wide viewingangle the viewing angle is 6 o’clock direction. LED Backlight-driving DC/DC converter is not built in this module.
