1. OVERVIEW
1.1. Description: The AA121SK22 is a 12.1-inch color TFT-LCD (Thin Film Transistor Liquid Crystal
Display) module composed of a LCD panel, driver ICs, a control circuit, and a backlight. Input power
voltage is either 3.3 or 5.0 V, not including power for the backlight. Both 3.3V-CMOS and
5.0V-CMOS levels are acceptable for logic input. Data and control signal interface is digital CMOS.
The display module supports 262,144 colors by applying 18 bits digital data (6 bits per sub pixel,
RGB). The display module resolution is 800 × 600 pixels. Inverter for backlight is not included in this
module.

3.4.6. The operating frequency of the backlight inverter may produce interference with horizontal
synchronous frequency. This may cause a horizontal ‘beat’ to be visible on the display. To avoid this
phenomenon, please adjust backlight inverter frequency and keep the inverter as far
from module
(physically) as possible. Use of shielding between the backlight inverter and the display module is
also effective to reduce interference.
3.4.7. Lamp life time is defined as the time either when the luminance becomes 50% of the initial value
under the standard condition, or when the starting lamp voltage does not meet the value specified in
this table.
3.4.8. The life time of the backlight depends on the ambient temperature. The life time will decrease under
low/high temperature.

10. HANDLING PRECAUTIONS FOR TFT-LCD MODULE - Please observe the
recommendations included in this paragraph when handling the TFT-LCD
modules !
10.1. ASSEMBLY PRECAUTIONS
10.1.1. Please use the mounting hole on the module corners for installation and avoid bending or wrenching
LCD during assembly process. Do not drop, bend or twist the TFT-LCD module during handling.
10.1.2. Guidelines for designing the TFT-LCD module enclosure:
10.1.2.1. Housing case must be designed carefully so as not
wrench module. Mechanical stress to the TFT-LCD module may degrade the reliability and overall
performances of the display (like luminance uniformity degradation…etc.).
10.1.2.2. Keep sufficient clearance between LCD module back surface and housing when
mounted. Approximately 1.0 mm of the clearance in the design is recommended taking into account
the tolerance of LCD module thickness and mounting structure height on the housing.
10.1.2.3. When some parts, such as FPC cable and ferrite plate, are installed underneath the LCD
sufficient clearance is required, such as 0.5mm. This clearance is to be reconsidered when
additional parts are inserted for EMI countermeasures.
10.1.2.4. Choose carefully the inverter location to avoid any stress to the lamp cable. The lamp cable also
should not interfere with the module installation
10.1.2.5. Keep sufficient clearance between LCD module and the others components, such as inverter and
speaker so as not to interfere with the LCD module. Approximately 1.0 mm of the clearance in the
design is recommended.
10.1.2.6. Please connect the metal frame of the m
noise and EMI.
10.1.3. Do not apply pressure or scratch LCD panel surface with anything hard. Do not soil LCD panel
surface by touching with bare hands. (The anti-glare surface treatment is only effective when
module surface of the display is clean and unmarred.)
10.1.4. Do not apply pressure on any parts on the rear side such as source TCP, gate TCP, control circuit
board and FPCs during handling LCD module.
10.1.5. Wipe off LCD panel surface with absorbent cotton or soft cloth to
10.1.6. Wipe off immediately any liquids which may have accidentally being sprayed on LCD panel surface.
Droplets on the LCD panel surface may alter the quality of the image.
10.1.7. Do not disassemble the TFT-LCD module for any reasons. By doing so you void the
TFT-LCD module and is very likely that the performances will be degraded considerably.
10.1.8. Do not touch metal frames with bare hands and soiled gloves. If fingerprints or dirt are not cleaned
immediately with solvent it is very likely that permanent m
10.1.9. Disconnect the lamp wires before handling the inverter. Otherwise, it is possible to damage the lamp
and or the lamp wires by pulling it together with the inverter.
10.2. OPERATING PRECAUTIONS
10.2.1. Turn off the power supply
10.2.2. Do not change the setting of the adjustable resistors on TFT-LCD module subassemblies. The
adjustable resistors are properly set at the factory and any deviation from the factory setting will
compromise the performances of the TFT-LCD module.
10.2.3. When evaluating the optical characteristics of the display please note that will take longer time for the
backlight to stabilize if the ambient temperature is at the lower end of the temperature range.
10.2.4. Sudden changes of the ambient temperature may

10.2.5. Follow-up the general safety rules applying to generic electronic products.

10.3. PRECAUTIONS WITH ELECTRONICS
10.3.1. This LCD module uses CMOS integrated circuits and other components subject to be affected by
electrostatic discharges. Use ESD protection equipment and follow all ESD safety procedures when
handling the TFT-LCD modules.
10.3.2. Please remove protection film very slowly from the
discharge. It is recommended to lift the protection film starting from the lower left corner of the
module, and pulling diagonally toward the upper right corner.
10.4. STORAGE PRECAUTIONS
10.4.1. Do not leave the LCDs in the environment of high hu
10.4.2. Do not expose the TFT-LCD modules to temperatures below −20°C.
10.5. SAFETY PRECAUTIONS
10.5.1. When disposing LCDs it is recommended to break them into pieces. The broken pieces should be
washed with solvents such as acetone and ethanol. The residual solvent fro
burned.
10.5.2. If any liquid leaks out of a damaged glass cell and comes in contact with the hands, wash it off
thoroughly with soap and water.
10.6. OTHERS
10.6.1. Exposing the TFT-LCD module to strong incident light may negatively affect the display
characteristics
LCD module to direct sunlight or light with strong ultraviolet content.
10.6.2. Avoid any contact of the TFT-LCD module front surface with other objects or materials.
10.7. PACKAGING AND SHIPPING
10.7.1. Packaging box and inner case for
scratching during transportation. Do not open the packaging box unnecessarily.
10.7.2. Do not stack more than 5 boxes on top of each other because stack of 5 is maximum designed limit.
Do not turn over the boxes.
10.7.3. Avoid
10.7.4. Packaging box and the inner structures of it are made of cardboard. Avoid having the boxes in
