4).The life time of the lamp is related to the current of the lamp, so please according to the description
of the “(b) backlight” on page 7.
5).Test Condition: IEC 1000-4-2
VESDt: Contact discharge to input connector; VESD
6).If you operate the product in normal temperature range, the center surface of panel should be under

7).When lamp current is out of the absolute maximum range, the life will fall rapidly or shown
unusual sign.
IL min 2mA only for test only, but we can’t guarantee the lifetime and performance.
8).Delay lighting testing needs the volt above start voltage Vrms. Before the procedure tube needs
typical lighting for 1 minute and stay in the temperature 25±2к for 24 hours and then testing in the
same condition in dark room.

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 for fill the conditions
