Note2 : The lamp power consumption shown above does include loss of external inverter at 25℃.
Note3 : The life is determined as the time at which luminance of the lamp is 50% compared to that
Note1 : The specified current and power consumption are under the Vcc=5.0V, 25℃, fv= 65Hz,
The output of the inverter must have symmetrical (negative and positive) voltage waveform and
symmetrical current waveform (Asymmetry ratio is less than 10%). Please do not use the inverter
which has asymmetrical voltage and asymmetrical current and spike wave. Requirements for a
system inverter design which is intended to have a better display performance, a better power
efficiency and a more reliable lamp. It shall help increase the lamp lifetime and reduce its leakage
current.
a. The asymmetry rate of the inverter current and voltage waveform should be 10%
fCLK=25Mhz condition whereas mosaic pattern (8x6) is displayed and fv is the frame
frequency.
Apply the lamp voltage within the LCD operating range. When the backlight turns on
before the LCD operation or the LCD turns off before the backlight turns off, the display
may momentarily become abnormal.
Caution : The above on/off sequence should be applied to avoid abnormal function in the
display. In case of handling, make sure to turn off the power when you plug the cable into
the input connector or pull the cable out of the connector.
The used lamp current is the lamp typical current
of initial value at the typical lamp current on condition of continuous operating at 25±2℃
