[Note]
1).The relative temperature and humidity range are as below sketch, 90%RHMax.(Ta40).
2).The maximum wet bulb temperature 39(Ta40) 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-aching.
4).The life time of the lamp is related to the current of the lamp, so please according to the
description of the "(2) backlight" on page 8.
5).Test Condition: IEC 1000-4-2
VESDt: Contact discharge to input connector; VESDC: Contact discharge to module
6).If you operate the product in normal temperature range, the center surface of panel should be
under 60.
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
