* The device listed in these technical literature sheets was designed and manufactured for use in AV equipment.
* In case of using the device for applications such as control and safety equipment for transportation (aircraft, trains,
automobiles, etc.), rescue and security equipment and various safety related equipment which require higher
reliability and safety, take into consideration that appropriate measures such as fail-safe functions and redundant
system design should be taken.
* Do not use the device for equipment that requires an extreme level of reliability, such as aerospace applications,
telecommunication equipment (trunk lines), nuclear power control equipment and medical or other equipment for
life support.

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, inverter circuit and back light
system etc. Graphics and texts can be displayed on a 1280×RGB×768 dots panel with 16,777,216 colors by
using LVDS (Low Voltage Differential Signaling) to interface, +5V of DC supply voltages and supply voltage for
back light.
This module also includes the DC/AC inverter to drive the CCFT .
And in order to improve the response time of LCD, this module have decided to apply the O/S (over shoot)driving
▲１
technology for the control circuit.In the O/S driving technology,signals are being applied to the Liquid Crystal
according to a pre-fixed process as an image signal of the present frame in case a difference is found between image
signal of the previous frame and that of the current frame after comparing them.
By using the captioned process,the image signals of this LCD module are being set so that image response can be
completed within one frame,as a result,image blur can be improved and clear image performance can be realized.
