Note 7-1 : To test the current dissipation of Vcc, using the “color bars” testing pattern shown

as below

2345678

Idd current dissipation testing pattern

Note 7-2 : The back-light driving waveform should be as closed to sine-wave as possible.

In order to satisfy the quality of B/L , no matter use what kind of inverter , the

output lamp current must between Min. and Max. to avoid the abnormal

display image caused by B/L.

Note 7-3 : Not including the efficiency of backlight DC/AC inverter

The kick-off time must larger than 1 second

Note 7-4 : Lamp current is measured with current meter for high frequency as shown below

Note 7-5: The life time is determined as the time at which brightness of lamp is 50% compare

to that of initial value at the typical lamp current.
