1.0 Handling Precautions

1) Do not press or scratch the surface harder than a HB pencil lead because the polarizers are very fragile and could be easily damaged.

2) Be sure to turn off power supply when inserting or disconnecting from input connector.

3) Wipe off water droplets or oil immediately. Long contact with the droplets 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) Protect the module from static electricity and insure proper grounding when handling. Static electricity may cause damage to the CMOS Gate Array IC.

7) Do not disassemble the module.

8) Do not press the reflector sheet at the back of the module.

9) Avoid damaging the TFT module. Do not press the center of the CCFL Reflector when it was taken out from the packing container. Instead, press at the edge of the CCFL Reflector softly.

10) Do not rotate or tilt the signal interface connector of the TFT module when you insert or remove other connector into the signal interface connector.

11) Do not twist or bend the TFT module when installation of the TFT module into an enclosure (Notebook PC Bezel, for example). It should be taken into consideration that no bending/twisting forces are applied to the TFT module from outside when designing the enclosure. Otherwise the TFT module may be damaged.

12) Cold cathode fluorescent lamp in LCD contains a small amount of mercury. Please follow local regulations for disposal.

13) The LCD module contains a small amount of material that has no flammability grade, so it should be supplied by power complied with requirements of limited power source (2.11, IEC60950 or UL1950).

14) The CCFL in the LCD module is supplied with Limited Current Circuit (2.4, IEC60950 or UL1950). Do not connect the CCFL in Hazardous Voltage Circuit.

Note 1: DP-1 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 ver 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 start-up voltage. It is recommended to keep on applying start-up voltage for 1 [Sec] until discharge. *5 The CCFL inverter operating frequency must be carefully chosen so that no interfering noise stripes on the screen were induced. *6 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 ICCFL is less than 4mA. Note 3: The CCFL inverter operating frequency should be carefully determined to avoid interference between

inverter and TFT LCD.

Note 4: The inverter open voltage should be designed larger than the lamp starting voltage at T=0

backlight may be blinking for a moment after turning on or not be able to turn on. The open voltage should be measured after ballast capacitor. If an inverter has shutdown function it should keep its open voltage. for longer than 1 second even if lamp connector is open.
