Note 1: Definition of viewing angle
Viewing angle is the measurement of contrast ratio≧10, or ≧5, 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° (θ) horizontal left and right and 90° (Φ) 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 4: Measurement method
The LCD module should be stabilized at given temperature for 30 minutes to avoid abrupt temperature
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.

Note 5: Definition of response time:
The output signals of photo detector are measured when the input signals are changed from “Full Black” to
“Full White” (rising time), and from “Full White” to “Full Black” (falling time), respectively. The response time
is interval between the 10% and 90% of amplitudes. Please refer to the figure as below.

5.2 Backlight Unit
Parameter guideline for CCFL Inverter is under stable conditions at 25 (Room Temper℃ature):
Parameter Min. Typ. Max. Unit Condition
CCFL Standard Current(ISCFL) 7.07.5 8.0 [mA] rms Note 2
CCFL Power Consumption(PCFL) - 19.6 21.56 [Watt] Note 6
CCFL Life Time(LTCFL) 30,000 - - [Hour] Note 2,7
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.
www.jxlcd.com
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 25±2℃.
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 1,690
voltage. Lamp units need 1,690 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 current.

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.
