1. Applicable Scope
This technical literature is applicable to TFT-LCD Module “LQ043T1DG29”.
2. General Description
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 IC, Input FPC, a back light unit and touch panel.
Graphics and texts can be displayed on a 480 x 272 x RGB dots panel with about 262k colors by supplying
18bit data signals (6bit x RGB), four timing signals, 3wires 24bit serial interface signals, logic (Typ. +3.3V),
analog (Typ. +3.3V) supply voltages for TFT-LCD panel driving and supply voltage for back light.

10. Handling of modules
10-1. Inserting the FPC into its connector and pulling it out.
1) Be sure to turn off the power supply and the signals when inserting or disconnecting the cable.
2) Please insert for too much stress not to join FPC in the case of insertion of FPC.
10-2. Handling of FPC
1) The bending radius of the FPC on flexible part should be more than R0.6mm, and it should be bent evenly.
2) Do not dangle the LCD module by holding the FPC, or do not give any stress to it.
3) Do not add stress to the terminal area of FPC and LCD panel.
4) Do not bend FPC to the display direction when handling and mounting.
10-3. Mounting of the module
1) The module should be held on to the plain surface. Do not give any warping or twisting stress to the module.
Refer to 18.Outline Dimensions about the handling area in surface and gasket area in back. When LCD
2
surface is pushed by the power over 300gf/cm , with use of handling area, the pooling may occur at a
different place from the pushed place. Because there is a grade difference in the pooling, check and judge
after mounting.
2) Please consider that GND can ground a modular metal portion etc. so that static electricity is not charged to
the module.
10-4. Cautions in assembly / Handling pre cautions.
The protect film is attached on the module surface. Remove the film carefully to static electricity as much as
possible just before use.
1) Notes about removing the protect film on the module surface
A） Work environments
Since removing laminator may causes electrostatic charge that tends to attract dust, the following work
environment would be desired.
a) Implement more than 1MΩ conductive treatment (by placing a conductive mat or applying conductive
paint on the floor or tiles.）
b) No dusts come in to the working room. Place an adhesive, anti-dust mat at the entrance of the room.
c) Humidity of 50 to 70% and temperature of 15 to 27C are desirable.
d) All workers wear conductive shoes, conductive clothes, conductive fingerstalls and grounding belts
without fail.
B） Instruction for working
Wind Flow

Blower
The best distance of use blower

tape
LCD Module
Input CN side
LD-25258A-23
a) Wind direction of an antistatic blower should slightly downward to properly blow the module.
The distance between the blower and the module should be the best distance of use blower.
Also, pay attention to the direction of the module. [See the above]
c) To prevent polarizer from scratching, adhesive tape (cellophane tape) should be stuck at the part of
laminator sheet, which is closed to blower. [See the above]
b) Pull slowly adhesive tape to peel the laminator off, with spending more than 5 second.
c) The module without laminator should be moved to the next process to prevent adhesion of dust.
2) How the remove dust on the polarizer
a) Blow out dust by the use of an N2 blower with antistatic measures taken. Use of an ionized air Gun is
recommendable.
b) When the panel surface is soiled, wipe it with soft cloth.
3) In the case of the module’s metal part (shield case) is stained, wipe it with a piece of dry, soft cloth. If rather
difficult, give a breath on the metal part to clean better.
4) As a glass substrate is used for the TFT-LCD panel, if it is dropped on the floor or hit by something hard, it may
be broken or chipped off. Take care of handling.
5) Since CMOS LSI is used in this module, take care of static electricity and take the human earth into
consideration when handling.
10-5. Others
1) Regarding storage of LCD modules, avoid storing them at direct sunlight-situation.
You are requested to store under the following conditions:
(Environmental conditions of temperature/humidity for storage)
a) Temperature: 0 to 40C
b) Relative humidity : 95% or less
As average values of environments (temperature and humidity) for storing, use the following control
guidelines:
Summer season: 20 to 35C, 85％ or less Winter season: 5 to 15C, 85％ or less.
If stored under the conditions of 40C and 95% RH, cumulative time of storage must be less than 240
hours.
2) If stored at temperatures below the rated values, the inner liquid crystal may freeze, causing cell destruction.
At temperatures exceeding the rated values for storage, the liquid crystal may become isotropic liquid,
making it no longer possible to come back to its original state in some cases. Please store as near room
temperature as possible.
3) If the LCD is broken, do not drink liquid crystal in the mouth. If the liquid crystal adheres to a hand or foot or to
clothes, immediately cleanse it with soap.
4) If a water drop or dust adheres for a long time, it is apt to cause deterioration. Wipe it immediately.
5) Be sure to observe other caution items for ordinary electronic parts and components.
6) When handling and assembling this LCD module, avoid using and storing this module for a long time at the
place where Oxidization gas and Reduction gas (SO2, H2S etc) including the reagent, the adhesives and
resin etc which generate these gases may exist in the atmosphere because of corrosion, discoloration, an
abnormal display and operation of this module. An abnormal display by changing in quality of the polarizer
might occur regardless of contact or no contact to the polarizing plate, because of epoxy resin (amine
LD-25258A-24
system curing agent) that comes out from the material and the packaging material used for the set side, the
silicon adhesive (dealcoholization system and oxime system), and the tray blowing agents (azo-compound),
etc. Please confirm adaptability with your employed material.

1) Disassembling the module can cause permanent damage and you should be strictly avoided.
2) Please be careful that you don’t keep the screen displayed fixed pattern image for a long time, since retention
may occur.
3) If you pressed down a liquid crystal display screen with your finger and so on, the alignment disorder of liquid
crystal will occur. And then It will become display fault.
Therefore, be careful not to touch the screen directly, and to consider not stressing to it.
4) If any problem arises regarding the items mentioned in this technical literature or otherwise, it should be
discussed and settled mutually in a good faith for remedy and/or improvement.
