*1) If you operate the product in normal temperature range, the center surface of panel

should be under 60℃.

*2) The relative temperature and humidity range are as below sketch, 90%RHMax.(Ta≦40

℃) . The maximum wet bulb temperature ≦39℃(Ta＞40℃) and without dewing.。

*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.。

*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 5.

*5) Test Condition: IEC 1000-4-2 ,

VESDt：Contact discharge to input connector；VESDC：Contact discharge to module
*6) When light tube volt volume pass its absolute maximum range，the life will fall rapidly or

shown unusual sign.

IL min 2~3mA only for test only, but we can’t guarantee the lifetime and performance

*7) Delay lighting testing needs the volt above 1940 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

*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.

*3) WL=IL x VL x 4

*4) It is necessary to consider the maximal value when design inverter，in order to

asure lighting.

*5)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

*6) 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
