The voltage and contrast settings must be configured before the LCD panel is ready for
operation.
controller.
The KS0713 LCD controller has several default settings of operation on the LCD panel
display PCB. Some settings are forced through direct bonding on the chip. The default
settings are:
ADC Select
- ADC = 0 SEG1 --> SEG132
- ADC = 1 SEG132 --> SEG1
SHL Select
- SHL = 0 COM1 --> COM64
- SHL = 1 COM64 --> COM1
