*1) Lamp Current measurement method ( The current meter is inserted in cold line)
Standard inverter : HIU-766 , typical luminance = 195 cd/m2 (5 point).
The time that module luminance reduced to 50% of initial value .
Base on Vs = (1460) V , Ta = 25°C, IL=6.0 mA continuous.

[Note 2]
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.
The degrees of unbalance: less than 10%
The ratio of wave height: less than √2 ±10%
Ip
I-p
The degrees of umbalance = Ip-I-p /Irms*100(%)
The ratio of wave height = Ip(or I-p)/Irms
Ip: lamp current high side peak, I-p: lamp current low side peak
[Note 3]
Definition of the lamp life time
Luminance: L under 50% of specification
Starting Lamp Voltage: VS < 1460V, Ta=25℃
VS < 1650V, Tb=0℃
