LD-7606- 6
[Notel] Vco~= OV: Luminance Max.
.,
VCON = 3.5V : Luminance Min.
[Note2] b case of VDD,VEE,VCOM are used Out of recommended operating conditions,
this Status may not properly indicate.
When pall-up Vst, the pall-up resister value is recommended 3.3K to 8.1 K Q.
[Note3] Lamp lifetime is defied that it applied either @ or @ under this condition
(Continuous turning on at Ta=25~, VCON= OV)
@ Brightness becomes 50% of the original value under standard condition.
@ Lamps can’t normally turn on at Ta=O~.
[Note4] These values we specfied as the ripple voltage of user’s power supply which input
the power to the backlight inverter. These do not include the returned ripple voltage _A
from backlight inverter.
