Note : 1. GND should be connected to the LCD module’s metal frame.
2. Minimum Brightness : Boost = 0.0V Maximum Brightness : Boost = 3.3V
“OPEN”
: Boost = 1.65V
3. Rising Edge : Lamp “ON” / Falling Edge : Lamp “OFF”
4. Pin#13 can be opened. ( if Pin #13 is open , EXTVBR-B is 100% )
5. Pin#14 can be opened. (Even though Pin #14 is GND or no connection, there is no effect on inverter operating)
6. Each impedance of pin #11, 12 and 13 is 140 [KΩ] , 400 [KΩ] and 330 [KΩ].
