[Note2] The influence of lamp frequency
This frequency range can keep the electrical and optical character within 10%
variation. Lamp frequency may interfere with horizontal synchronous frequency (or vitical
synchronous frequency), and then cause ripple noise on the display. Therefore, please
adjust the frequency of lamp input, be removed inveter from module as possible, or use
electronic shielding between inverter and module to avoid the interference.
[Note3] Definination of the lamp life
The luminance reduced to 50% of initial value.
[Note4] Wave request
The degrees of unbalance: less than 10%
The ratio of wave height: less than √2 ±10%
The degrees of umbalance = Ip-I-p /Irms*100(%)
The ratio of wave height = Ip(or I-p)/Irms
I
Ip: high side peak
I-p: low side peak
