1. Operating Precautions
1) Since front polarizer is easily damaged, please be cautious and not to scratch it.
2) Be sure to turn off power supply when inserting or disconnecting from input connector.
3) Wipe off water drop immediately. Long contact with water may cause discoloration or
spots.
4) When the panel surface is soiled, wipe it with absorbent cotton or soft cloth.
5) Since the panel is made of glass, it may be broken or cracked if dropped or bumped on
hard surface.
6) To avoid ESD (Electro Static Discharde) damage, be sure to ground yourself before handling
TFT-LCD Module.
7) Do not open nor modify the module assembly.
8) Do not press the reflector sheet at the back of the module to any direction.
9) In case if a module has to be put back into the packing container slot after it was taken
out from the container, do not press the center of the LED light bar edge. Instead, press
at the far ends of the LED light bar edge softly. Otherwise the TFT Module may be
damaged.
10) At the insertion or removal of the Signal Interface Connector, be sure not to rotate nor
tilt the Interface Connector of the TFT Module.
11) TFT-LCD Module is not allowed to be twisted & bent even force is added on module in a very
short time. Please design your display product well to avoid external force applying to module
by end-user directly.
12) Small amount of materials without flammability grade are used in the TFT-LCD module. The
TFT-LCD module should be supplied by power complied with requirements of Limited Power
Source (IEC60950 or UL1950), or be applied exemption.
13) Severe temperature condition may result in different luminance, response time and lamp
ignition voltage.
14) Continuous operating TFT-LCD display under low temperature environment may accelerate
lamp exhaustion and reduce luminance dramatically.
15) The data on this specification sheet is applicable when LCD module is placed in landscape
position.
16) Continuous displaying fixed pattern may induce image sticking. It’s recommended to use
screen saver or shuffle content periodically if fixed pattern is displayed on the screen.

Note 1: No Function failure occurs.
Note 2: According to EN61000-4-2, ESD class B: Some performance degradation allowed. No data lost
Self-recoverable. No hardware failures.
Note 3:ʳ
Water condensation is not allowed for each test items.
Each test is done by new TFT-LCD module. Don’t use the same TFT-LCD module repeatedly for reliability test.
The reliability test is performed only to examine the TFT-LCD module capability.
To inspect TFT-LCD module after reliability test, please store it at room temperature and room humidity for 24
hours at least in advance.

11 Safety
11.1 Sharp Edge Requirements
There will be no sharp edges or comers on the display assembly that could cause injury.
11.2 Materials
11.2.1 Toxicity
There will be no carcinogenic materials used anywhere in the display module. If toxic materials are
used, they will be reviewed and approved by the responsible AUO toxicologist.
11.2.2 Flammability
All components including electrical components that do not meet the flammability grade UL94-V1 in
the module will complete the flammability rating exception approval process.
The printed circuit board will be made from material rated 94-V1 or better. The actual UL flammability

rating will be printed on the printed circuit board.
11.3 Capacitors
If any polarized capacitors are used in the display assembly, provisions will be made to keep them
from being inserted backwards.
11.4 National Test Lab Requirement
The display module will satisfy all requirements for compliance to:
UL 1950, First Edition U.S.A. Information Technology Equipment
