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.

※ About the relation between data input and back light lighting, we recommend the above-mentioned input

sequence.

If the back light is switched on before a panel operation begins or after a panel operation stops, the screen may

not be displayed properly. But this phenomenon is not caused by change of an incoming signal, and does not

give damage to a liquid crystal display.

You need to send I2C command in order to start up. At first you send target device command, next input data format
command to each register. Slave address of target device should be set to “0x5A”. Register command table is as
follows:

[Note] We recommend SOC device of input signals are MSD3819JX, MSD3819SV (for digital TV) and MST6300RS,
MST6100VS (for analog TV).

Input data format diagrams are shown as follows. Please refer to section 8.2 about the range of TH, TV, THd and
TVd.

FST is a frame start pulse and output by the period of T

/2. LST is a line start pulse and output by the period of TH.

V

Since they can be used for control LED-ON/OFF duty, you may design any device able to control LED. These signals

are fixed at ‘Low’ in 2D mode.

GLS is a rectangular signal to control glass shutter timing, reversed by period of TV/2 and synchronized with FST.

You connect this signal to your emitter device in order to control opening and closing glass shutter. This signal is

fixed at ‘Low’ in 2D mode.

The way of glass shutter opening is depended on each 3D glass. Above diagram is an example of the condition;

・Left glass open and right glass close when GLS is ‘H’
・Left glass close and right glass open when GLS is ‘L’.

When you use 3D glass different from above mentioned type, you should reverse the order of LED-ON/OFF.

The total storage time (40°C, 95%RH): 240H or less

c) Sunlight:

Be sure to shelter a product from the direct sunlight.

d) Atmosphere:

Do not store in a place where exists the risk of corrosive gas (such as acid and alkali) or volatile solvents.

e) Prevent condensation:

Be sure to put cartons on a palette or base, don’t put it on the floor, and store them keeping off the wall.

Please take care of ventilation in storehouse and around cartons, and control temperature not to change abruptly

beyond the natural environment.

f) Storage life: 1 year

Precautions

14.

a) Be sure to turn off the power supply when inserting or disconnecting the cable.
b) Be sure to design the cabinet so that the module can be installed without any extra stress such as warp or

twist.

c) Since the front polarizer is easily damaged, pay attention not to scratch it.
d) Since long contact with water may cause discoloration or spots, wipe off water drop immediately.
e) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
f) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface. Handle with

care.

g) Since CMOS LSI is used in this module, take care of static electricity and take the human earth into

consideration when handling.

h) The module has some printed circuit boards (PCBs) on the back side, take care to keep them form any stress

or pressure when handling or installing the module; otherwise some of electronic parts on the PCBs may be

damaged.

i) Observe all other precautionary requirements in handling components.
j) When some pressure is added onto the module from rear side constantly, it causes display non-uniformity

issue, functional defect, etc. So, please avoid such design.

k) When giving a touch to the panel at power on supply, it may cause some kinds of degradation. In that case,

once turn off the power supply, and turn on after several seconds again, and that is disappear.

l) When handling LCD modules and assembling them into cabinets, please be noted that long-term storage in

the environment of oxidization or deoxidization gas and the use of such materials as reagent, solvent,
adhesive, resin, etc. which generate these gasses, may cause corrosion and discoloration of the LCD

modules.

m) This LCD module is designed to prevent dust from entering into it. However, there would be a possibility to

have a bad effect on display performance in case of having dust inside of LCD module. Therefore,

please ensure to design your TV set to keep dust away around LCD module.
