1. GENERAL DESCRIPTION
1.1 OVERVIEW
This module is color active matrix LCD module incorporating amorphous silicon TFT(Thin Film Transistor)
LCD panel. It is composed of a color TFT-LCD panel, driver ICs, LED Backlight… etc. Graphics and texts can be
displayed on a 1366×RGB×768 dots panel with about 16.7M colors (R/G/B 6bits+Hi FRC data in each color) by
using LVDS(Low Voltage Differential Signaling) to interface, +5V of DC supply voltage.

*3) No condensation.
[Note 2] The maximum operating temperature is based on the test condition that the surface temperature of
display area is less than or equal to 50ºC with LCD module alone in a temperature controlled
chamber. Thermal management should be considered in your product design to prevent the surface
temperature of display area from being over 60ºC. The range of operating temperature may degrade
in case of improper thermal management in your product design.
[Note 3] The rating of environment is base on LCD module. Leave LCD cell alone, this environment condition
can’t be guaranteed. Except LCD cell, the customer has to consider the ability of other parts of LCD
module and LCD module process.

※ About the relation between data input and back light lighting, please base on the above-mentioned input
sequence.
※
When back light is switched on before panel operation or after a panel operation stop, it may not display
normally. But this phenomenon is not based on change of an incoming signal, and does not give damage
to a liquid crystal display.
※ VCC-dip conditions:
(1) When 3.6V≦VCC(min)<4.5V, td≦10 ms
(2) When VCC <3.6 V, VCC-dip conditions should also follow the VCC-turn-on conditions.

IRush Measurement Condition:
The duration of rising time of power input is 470us.
