2. Need you to compress the screen and PCB tighter, might get loose after the delivery.
3 Use a 3.3V controller, otherwise, the display could be quite vague.
Power supply voltage:2.7V-3.3V,5V is OK, but part of the screen becomes black when tested
Data interface level:2.7-5V
Backlight power supply voltage: highest 3.3V
