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
spot.
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.

Product Specification
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 ignition 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 3mA.
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.
AU OPTRONICS CORPORATION
Note 5: CCFL inverter should be able to give out a power that has a generating capacity of over 1290 voltage.
Lamp units need 1290 voltage minimum for ignition.
Note 6: The variance of CCFL power consumption is ±10%. Calculator value for reference (ISCFL × VCFL × 2=
PCFL)
Note 7: Definition of life: brightness becomes 50%. The typical life time of CCFL is under the condition at 6.5
mA lamp current.
Note 8: Requirement for system inverter design, which is intended to have a better display performance, a
better power efficiency and a more reliable lamp. It should help increase the lamp lifetime and reduce
its leakage current.
The frequency range will not affect to lamp lifetime and reliability characteristics. (Reference value)
The rate of unsymmetrical of lamp lighting waveform is shown (Lamp current waveform and lamp
voltagewaveform) at 5% or less.
