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
