Note 1: Definition of viewing angle, measured by ELDIM (EZContrast 88)
Viewing angle is the measurement of contrast ratioЊ10, or Њ5, 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° (Ӱ) horizontal left and right and 90° (ӥ) 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.

change during measuring. In order to stabilize the luminance, the measurement should be executed after
lighting Backlight for 30 minutes in a stable, windless and dark room. ʳ

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: CCFL standard current is measured at 252к.
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 1,200
voltage. Lamp units need 1,200 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 life: brightness becomes 50%. The typical life time of CCFL is on the condition at 7.5 mA
lamp output current.

4 RxOIN1+ Positive LVDS differential data input (Odd data)
5 RxOIN2- Negative LVDS differential data input (Odd data, H-Sync,V-Sync,DSPTMG)
6 RxOIN2+ Positive LVDS differential data input (Odd data, H-Sync,V-Sync,DSPTMG)
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
-2˃к to 6˃к, 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.
