The problem may be caused by several factors
1. Power supply problem: the power supply is not properly connected.One line is energized and one line is not energized, resulting in display spacing.
2. Control alignment: the control card alignment is not properly connected, resulting in the data cannot be transmitted.
3. Control card problem: adjust the OE polarity of control card.
4. Control card software and control card mismatch: please confirm that the control card software is provided by the control card manufacturer.
