[Note 1] The relative temperature and humidity range are as below sketch, 90%RHMax.(Ta
≦40℃) .
[Note 2] The maximum wet bulb temperature ≦39℃(Ta>40℃) and without dewing.。
[Note 3] If you use the product in a environment which over the definition of temperature and
humidity too long to effect the result of eye-atching.。
[Note 4] The life time of the lamp is relate to the current of the lamp, so please accronding to
the description of the “(b) backlight” on page 6.
[Note 5] Test Condition: IEC 1000-4-2 ,

[Note 6] If you operate the product in normal temperature range, the center surface of panel
should be under 60℃.
[Note 7] When lamp current is out of the absolute maximum range,the life will fall rapidly
or shown unusual sign.
IL min 3mA only for test only, but we can’t guarantee the lifetime and performance
[Note 8] Delay lighting testing needs the volt above start volagte Vrms.Before the procedure
tube needs typical lighting for 1 minute and stay in the temperature 25±2℃ for 24
hours and then testing in the same condition in dark room .

[Note ] Measuring inverter Type:M063-4
If the waveform of light up-driving is asymmetric, the distribution of mercury inside
the lamp tube will become unequally or will deplete the Ar gas in it. Then it may
cause the abnormal phenomenon of lighting-up. Therefore, designers have to try
their best to forfill the conditions under the inverter designing-stage as below:
•The degrees of unbalance: <10%
•The ratio of wave height:<√2 ±10%
℃
A:The degrees of unbalance =︱Ip – I-p︱/ Irms ×100 (%)
B:The ratio of wave height = Ip (or I-p) / Irms

[Note 2]
1.Frequency in this range can mala the characterisitics of electric and optics
maintain in +/- 10% except hue.
2.If the lamp frequency can be maintain in 50~60KHz, the better charactristics of
the electrical and the optical can be presented.
3.If the operating frequency is 40~80 KHz, the life time and the reliability of the lamp
will not be affect.
4.Lamp frequency of inverter may produce interference with horizontal synchronous
frequency,and this may cause horizontal beat on the display.Therefore, please
adjust lamp frequency, and keep inverter as far from module as possible or use
electronic shielding between inverter and module to avoid the interference.
[Note 3] Definition of the lamp life time: Luminance (L) under 50% of specification
starting lamp voltage or starting lamp voltage is more than 130% of the initial
value
[Note 4] The condition of Turn-on and Turn-off operation is as below:
a. Lamp current is 7.0mA
b. Frequency is 10 sec.(on)/10 sec.(off)
c. Repeat it for 10 thousand times
d. The result of eye-atching of the lamp hue is normal, and can switch the lamp.
It should not have motion fail when starting lamp voltage is lower than 130% of
the initial value
[Note 5] It is necessary to consider the maximal value when design inverter,in order to
asure lighting.
