1. OVERVIEW
T-51638D084-FW-A-AA is 8.4" color TFT-LCD (Thin Film Transistor Liquid Crystal Display)
module composed of LCD panel, driver ICs, control circuit, and backlight unit.
By applying 6 bit digital data, 640
480, 262,144-color images are displayed on the 8.4" diagonal
screen. Input power voltage is single 3.3V for LCD driving.
Inverter for backlight is not included in this module. General specifications are summarized in
the following table:

*2) Lamp frequency of inverter may produce interference with horizontal synchronous frequency,
and this may cause horizontal beat on the display. Therefore, please adjust lamp frequency, and
keep inverter as far from module as possible or use electronic shielding between inverter and
module to avoid the interference.

10. HANDLING PRECAUTIONS FOR TFT-LCD MODULE
Please pay attention to the followings in handling TFT-LCD products;
(1) ASSEMBLY PRECAUTION
a. Please use the mounting hole on the module in installing and do not bending or wrenching
LCD in assembling. And please do not drop, bend or twist LCD module in handling.
b. Please design display housing in accordance with the following guide lines.
(a) Housing case must be designed carefully so as not to put stresses on LCD all sides and not
to wrench module. The stresses may cause non-uniformity even if there is no non-
uniformity statically.
(b) Keep sufficient clearance between LCD module back surface and housing when the LCD
module is mounted. Approximately 1.0mm of the clearance in the design is recommended
taking into account the tolerance of LCD module thickness and mounting structure height
on the housing.
(c) When some parts, such as, FPC cable and ferrite plate, are installed underneath the LCD
module, still sufficient clearance is required, such as 0.5mm. This clearance is, especially,
to be reconsidered when the additional parts are implemented for EMI countermeasure.
(d) Design the inverter location and connector position carefully so as not to give stress to
lamp cable, or not to interface the LCD module by the lamp cable.
(e) Keep sufficient clearance between LCD module and the others parts, such as inverter and
speaker so as not to interface the LCD module. Approximately 1.0mm of the clearance in
the design is recommended.
c. Please do not push or scratch LCD panel surface with anything hard. And do not soil LCD
panel surface by touching with bare hands. (Polarizer film, surface of LCD panel is easy to be
flawed.)
d. Please do not press any parts on the rear side such as source TCP, gate TCP, control circuit
board and FPCs during handling LCD module. If pressing rear part is unavoidable, handle
the LCD module with care not to damage them.
e. Please wipe off LCD panel surface with absorbent cotton or soft cloth in case of it being soiled.
f. Please wipe off drops of adhesives like saliva and water on LCD panel surface immediately.
They might damage to cause panel surface variation and color change.
g. Please do not take a LCD module to pieces and reconstruct it. Resolving and reconstructing
modules may cause them not to work well.
h. Please do not touch metal frames with bare hands and soiled gloves. A color change of the
metal frames can happen during a long preservation of soiled LCD modules.
i. Please pay attention to handling lead wire of backlight so that it is not tugged in connecting
with inverter.

j. Be sure to connect the cables and the connectors correctly.
k. Please connect the metal frame of LCD module to GND in order to minimize the effect of
external noise and EMI.
(2) OPERATING PRECAUTIONS
a. Please be sure to turn off the power supply before connecting and disconnecting signal input
cable.
b. Please do not change variable resistance settings in LCD module. They are adjusted to the most
suitable value. If they are changed, it might happen LCD does not satisfy the characteristics
specification.
c. LCD backlight takes longer time to become stable of radiation characteristics in low
temperature than in room temperature.
d. A condensation might happen on the surface and inside of LCD module in case of sudden change
of ambient temperature.
e. Please pay attention not to display the same pattern for very long time. Image might stick on
LCD. Even if image sticking happens, it may disappear as the operation time proceeds.
f. Please obey the same safe instructions as ones being prepared for ordinary electronic products.
(3) PRECAUTIONS WITH ELECTROSTATICS
a. This LCD module use CMOS-IC on circuit board and TFT-LCD panel, and so it is easy to be
affected by electrostatics. Please be careful with electrostatics by the way of your body
connecting to the ground and so on.
b. Please remove protection film very slowly from the surface of LCD module to prevent from
electrostatics occurrence.
(4) STORAGE PRECAUTIONS
a. Please do not leave the LCDs in the environment of high humidity and high temperature such as
60C90%RH.
b. Please do not leave the LCDs in the environment of low temperature; below -20C.
(5) SAFETY PRECAUTIONS
a. When you waste damaged or unnecessary LCDs, it is recommended to crush LCDs into pieces
and wash them off with solvents such as acetone and ethanol, which should later be burned.
b. If any liquid leaks out of a damaged glass cell and comes in contact with the hands, wash off
thoroughly with soap and water.
c. Be sure to turn off the power supply when inserting or disconnecting the cable.

d. Inverter should be designed carefully so as not to keep working in case of detecting over current
or open circuit on the lamp.
(6) OTHERS
a. A strong incident light into LCD panel might cause display characteristics changing inferior
because of polarizer film, color filter, and other materials becoming inferior. Please do not
expose LCD module direct sunlight and strong UV rays.
b. Please pay attention to a panel side of LCD module not to contact with other materials in
preserving it alone.
c. For the packaging box, please pay attention to the followings;
(a) Packaging box and inner case for LCD are designed to protect the LCDs from the damage or
scratching during transportation. Please do not open except picking LCDs up from the box.
(b) Please do not pile them up more than 6 boxes. (They are not designed so.) And please do not
turn over.
(c) Please handle packaging box with care not to give them sudden shock and vibrations. And
also please do not throw them up.
(d) Packaging box and inner case for LCDs are made of cardboard. So please pay attention not
to get them wet. (Such like keeping them in high humidity or wet place can occur getting
them wet.)
