1. OVERVIEW

T-51512D121J-FW-A-AB is 12.1" 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, 800

600, 260 K-color images are displayed on the 12.1" diagonal

screen. Input power voltage is single 3.3V or 5.0V for LCD driving. Both 3.3 V-CMOS and 5.0 V-
CMOS level voltage are acceptable for logic input voltage.

Inverter for backlight is not included in this module. General specifications are summarized in the

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.

3) Lamp life time is defined as the time either when the brightness becomes 50% of the initial value, or

when the starting lamp voltage does not meet the value specified in this table.

4) The life time of the backlight depends on the ambient temperature. The life time will decrease under

low/high temperature.

5) Please use the inverter which has symmetrical current wave form as follows,

The degree of unbalance: less than 10%
The ratio of wave height: less than 2 ±10%

11. 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.

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 handle metal frame carefully to avoid getting hurt because edge of metal frame is very

sharp.

T-51512D121J-FW-A-AB (AB) No. 2003-0101

OPTREX CORPORATION

Page 19/32

j. Please pay attention to handling lead wire of backlight so that it is not tugged in connecting with

inverter.

k. Be sure to connect the cables and the connecters correctly.
l. 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. The interface signal speed is very high. Please pay attention to transmission line design and other

high speed signal precautions to satisfy signal specification.

e. A condensation might happen on the surface and inside of LCD module in case of sudden change

of ambient temperature.

f. 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.

g. 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

60°C90%RH.

b. Please do not leave the LCDs in the environment of low temperature; below -20°C.

T-51512D121J-FW-A-AB (AB) No. 2003-0101

OPTREX CORPORATION

Page 20/32

(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 5 boxes. (They are not designed so.) And please do not

turn over.

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.)
