1. Application

This technical literature applies to the color 31.5” TFT-LCD Module (LK315T3LA94).

* This technical literature is proprietary product of SHARP CORPORATION (“SHARP”) and includes 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 this technical literature.

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

2. Overview

This module is a color active matrix LCD panel incorporating amorphous silicon TFT (Thin Film Transistor). It is
composed of a color TFT-LCD panel, driver ICs, Source-PWB, Control-PWB, optical sheets, LED-PWBs and
mechanical chassis.
Graphics and texts can be displayed on a 1366×RGB×768 dots panel with 16,777,216 colors by using LVDS (L

oltage Differential Signaling), I2C interface and +12V DC supply voltage, which are put into Control-PWB.

V
This module applies the Over Shoot driving (O/S driving) technology, signals are being applied to the Liquid
Crystal according to a pre-fixed process as image signals of the present frame when a difference is found between
image signals of the previous and current frame by comparing each other. The O/S driving technology makes the
Liquid Crystal response within 1 frame completely, motion blur reduce, so that clearer display performance can be
realized.

This module also can switch 2D and 3D mode to each other. In 2D mode, this can display images by converting
Single Frame Rate signals to Double Frame rate, while in 3D mode, by converting 3D input signals of Single Frame
Rate to pseudo-quarter Frame Rate. In both modes, FRC (Frame Rate Control) function operates.
