(a.) ELECTRICAL CHARACTERISTICS
LAMP LIFE-TIME (LT)
*1)Measure method：galvanometer connect to low voltage
*2) Frequency in this range can make the characterisitics of electric and optics maintain in +/- 10% except
*3) Definition of the lamp life time：
*4) For keeping good lighting situation, when design the inverter, it must be considered that the voltage large

hue.
Lamp Voltage(IL=6.0mA)
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.
a. Luminance (L) under 50% of specification starting lamp voltage
b. Starting Lamp Voltage: over130% of the initial value. Ta=25℃
Lamp Initial Voltage
Under optimum operate frequency range (50~80 KHz), will not effect panel life-time and relability .
