2. OVERVIEW

AA121TD11 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 or 8 bit digital data, 1280u 800, 262k-color or 16.7M-color images are displayed

on the 12.1” diagonal screen. Input power voltage is single 3.3 V for LCD driving.
The type of data and control signals are digital and transmitted via LVDS interface per Typ. 71
MHz clock cycle.

Driver circuit for LED backlight is not included in this module. General specifications are
summarized in the following table:

12. HANDLING PRECAUTIONS FOR TFT-LCD MODULE

Please pay attention to the followings in handling TFT-LCD products;

(1) ASSEMBLY PRECAUTION

a. Please mount the LCD module by using mounting hole with a screw clamping torque less than

0.5 Nm. Please do not bend or wrench the LCD module in assembling. Please do not drop,
bend or twist the 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 stress on LCD and not to wrench

module. If customer uses compression mounting, please evaluate housing case with LCD
carefully to avoid image quality issue caused by mechanical stress.

(b) Under high temperature environment, performance and life time of LED may heavily

shorten. When you design with our LCD product, please consider radiating heat and
ventilation for good heat management.

(c) 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.

(d) 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.

(e) Design the LED driver location and connector position carefully so as not to give stress to

LED backlight cable.

(f) Keep sufficient clearance between LCD module and the others parts, such as inverter and

speaker so as not to interfere the LCD module. Approximately 1.0 mm of the clearance in
the design is recommended.

(g) To avoid local elevation/decrease of temperature, considering location of heating element,

heat release, thermal design should be done.

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 wipe off LCD panel surface with absorbent cotton or soft cloth in case of it being soiled.
e. 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.
f. Please do not take a LCD module to pieces and reconstruct it. Resolving and reconstructing

modules may cause them not to work well.

g. 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.

h. Please handle metal frame carefully because edge of metal frame is very sharp.

i. Please connect the metal frame of LCD module to GND in order to minimize the effect of

external noise and EMI.
j. Be sure to connect the cables and the connecters correctly.

(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. The interface signal speed is very high. Please pay attention to transmission line design and

other high speed signal precautions to satisfy signal specification.
d. Condensation might happen on the surface and inside of LCD module in case of sudden change

www.panelook.com

of ambient temperature. Please take care so as not to cause any damage mentioned on (1)-d.
e. Please pay attention not to display the same pattern for very long time. Image sticking might

happen on LCD. Although image sticking may disappear as the operation time proceeds,

screen saver function is recommended not to cause image sticking.
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

LCD should be stored in the room temperature environment with normal humidity. The LCD
inventory should be processed by first-in first-out method.

(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 LED backlight cable.

d. LED driver should be designed carefully to limit or stop its function when over current is

detected on the LED.

(6) OTHERS

a. A strong incident light into LCD panel may cause deterioration to polarizer film, color filter,

and other materials, which will degrade the quality of display characteristics. Please do not

expose LCD module under strong Ultraviolet rays for a long time.
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 handling, please see and obey with the packaging specification

datasheet.
