1. Application
This technical literature applies to a color TFT-LCD module, LQ185T1LGN2.
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 and power supply circuit
and a backlight unit. Graphics and texts can be displayed on a 1366 x 3 x 768 dots panel with 16,777,216
colors by using LVDS (Low Voltage Differential Signaling) to interface and supplying +5V DC supply
voltage for TFT-LCD panel driving and supply voltage for backlight.
In this TFT-LCD panel , 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.
