1. Handling Precautions
1) Since front polarizer is easily damaged, pay attention 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 other soft cloth.
5) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface.
6) Since CMOS LSI is used in this module, take care of static electricity and insure human earth
when handling.
7) Do not open or modify the Module Assembly.
8) Do not press the reflector sheet at the back of the module to any directions.
9) In case if a Module has to be put back into the packing container slot after once it was taken out
from the container, do not press the center of the CCFL reflector edge. Instead, press at the far
ends of the CCFL Reflector 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) After installation of the TFT Module into an enclosure, do not twist nor bend the TFT Module even
momentary. At designing the enclosure, it should be taken into consideration that no
bending/twisting forces are applied to the TFT Module from outside. Otherwise the TFT Module
may be damaged.
12) Cold cathode fluorescent lamp in LCD contains a small amount of mercury. Please follow local
ordinances or regulations for disposal.
13) Small amount of materials having no flammability grade is used in the LCD module. The LCD module
should be supplied by power complied with requirements of Limited Power Source (IEC60950 or
UL1950), or be applied exemption.
14) The LCD module is designed so that the CCFL in it is supplied by Limited Current Circuit (IEC60950 or
UL1950). Do not connect the CCFL in Hazardous Voltage Circuit.

Note 1: Definition of viewing angle: measured by ELDIM (
Viewing angle is the measurement of contrast ratio 10, at the screen center, over a 180° horizontal
and 180° vertical range (off-normal viewing angles). The 180° viewing angle range is broken down as
follows; 90° () horizontal left and right and 90° () vertical, high (up) and low (down). The
measurement direction is typically perpendicular to the display surface with the screen rotated about its
center to develop the desired measurement viewing angle.

Note 1: Typ. are AUO recommended design points.
*1 All of characteristics listed are measured under the condition using the AUO test inverter.
*2 In case of using an inverter other than listed, it is recommended to check the inverter carefully.
Sometimes, interfering noise stripes appear on the screen, and substandard luminance or flicker
at low power may happen.
*3 In designing an inverter, it is suggested to check safety circuit very carefully. Impedance of
CCFL, for instance, becomes more than 1 [M ohm] when CCFL is damaged.
*4 Generally, CCFL has some amount of delay time after applying kick-off voltage. It is
recommended to keep on applying kick-off voltage for 1 [Sec] until discharge.
*5 Reducing CCFL current increases CCFL discharge voltage and generally increases CCFL
discharge frequency. So all the parameters of an inverter should be carefully designed so as not
to produce too much leakage current from high-voltage output of the inverter.
Note 2: It should be employed the inverter which has “Duty Dimming”, if IRCFL is less than 4mA.
Note 3: CCFL discharge frequency should be carefully determined to avoid interference between inverter
and TFT LCD.
Note 4: The frequency range will not affect to lamp life and reliability characteristics.
Note 5: CCFL inverter should be able to give out a power that has a generating capacity of over 1,500
voltage. Lamp units need 1,500 voltage minimum for ignition.
Note 6: The variance of CCFL power consumption is ±10%. Calculator value for reference (ISCFL × VCFL ×
4 = PCFL)
Note 7: Definition of CCFL life Time (LTCFL): brightness becomes 50%. (The typical life time of CCFL is on
the condition at 7.0 mA lamp current).

Contact Discharge: ± 8KV, 150pF(330Ω ) 1sec,
8 points, 25 times/ point.
ESD (ElectroStatic Discharge)
2
Air Discharge: ± 15KV, 150pF(330Ω ) 1sec
8 points, 25 times/ point.
Altitude Test
Operation:10,000 ft
Non-Operation:30,000 ft
Note 1: The TFT-LCD module will not sustain damage after being subjected to 100 cycles of rapid
temperature change. A cycle of rapid temperature change consists of varying the temperature from
-20 to 60, and back again. Power is not applied during the test. After temperature cycling, the
unit is placed in normal room ambient for at least 4 hours before power on.
Note 2: According to EN61000-4-2 , ESD class B: Some performance degradation allowed. No data lost.
Self-recoverable. No hardware failures.
