Note 1,2
Note : 1. Temperature and relative humidity range are shown in the figure below.
Wet bulb temperature should be 39 °C Max. and no condensation of water.
2. Gravity mura can be guaranteed under 40°C condition.
3. Abnormal visual problems by the surface temperature of front panel side can be occurred in
specific range (higher than 55 °C). But materials ( except : polarize stuff ) are not damaged
permanently in this range..

Note : 1. GND should be connected to the LCD module’s metal frame.
2. If Pin #11 is open, VBR-A = 1.65V, When apply over 1.65V( ~ 3.3V),
its luminance is increasing however lamp’s life time is decreasing.
It could be usable for boost up luminance when using DCR (=Dynamic contrast ratio) function only.
3. Minimum Brightness : VBR =0V Maximum Brightness : VBR = 3.3V
4. Even though Pin #14 is open, there is no effect on inverter operating, The output terminal of inverter
Ω Ω Ω5. Each impedance of pin #11,12 and 13 is 126[K ], 56[K ], 59[K ]
