1. Application

This specification applies to the color 26.0” Wide XGA TFT-LCD module LK260T3LA17.

* These specification sheets are proprietary products of SHARP CORPORATION (“SHARP”) and include materials
protected under copyright of SHARP. Do not reproduce or cause any third party to reproduce them in any form or by
any means, electronic or mechanical, for any purpose, in whole or in part, without the express written permission of
SHARP.

* 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.

* SHARP assumes no responsibility for any damage resulting from the use of the device that does not comply with

the instructions and the precautions specified in these specification sheets.

* Contact and consult with a SHARP sales representative for any questions about this device.

2. Overview

This module is a color active matrix LCD module incorporating amorphous silicon TFT (T
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 1366×RGB×768 dots panel with 16,777,216 colors by using
LVDS (L

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 when a difference is found between image
signal of the previous frame and that of the current frame after comparing them.

completed within one frame, as a result, image blur can be improved and clear image performance can be realized.

3. Mechanical Specifications

ow Voltage Differential Signaling) to interface, +12V of DC supply voltages.
This module also includes the DC/AC inverter to drive the CCFT. (+24V of DC supply voltage)
And in order to improve the response time of LCD, this module applies the Over Shoot driving (O/S driving)

By using the captioned process, the image signals of this LCD module are being set so that image response can be
