terminals should be connected to 3.3 V or 5.0 V.
2.
DE: DE/Fixed mode select is as follows.
Data enabled signal = DE mode
V
CC
or Open
3.
DPS: DPS changes display scan direction.
GND or Open = Scan direction will be decided by the setting of SW1.
V
CC
= Reverse scan
INPUT SIGNAL TIMING See (4) DISPLAY POSITION about another way for reversible scan. (DPS is
Open)
When DPS is V
CC
, reverse scan is selected even if SW1 is set at normal scan.
When DPS is GND, normal scan is selected even if SW1 is set at reverse scan.
4.
GND is connected to the frame of the LCD module.
= Fixed mode
