1. Applicable Scope
This specification applies to a color TFT-LCD Module "LQ121X3LG02".
2. General Description
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 and power supply circuit and a back light
unit.
Graphics and texts can be displayed on a 1024 x 3 x 768 dots panel with 262,144 colors by using LVDS
(Low Voltage Differential Signaling) to interface and supplying +3.3V DC supply voltage for TFT-LCD panel
driving and supply voltage for back light.
In this TFT-LCD panel, low reflection / color filters of excellent color performance and LED backlights of
high brightness are incorporated to realize brighter and clearer pictures, making this model optimum for use
in multi-media applications.
Optimum viewing direction is 6 o'clock.
LED Backlight-driving DC/DC converter is not built in this module.
