Yezhuoming's 8k screen only displays two grids when it is full of battery capacity. Because Yezhuoming's waterproof effect is not good, it is easy to get water, which will cause the line to get wet, so the resistance of the line will increase and the voltage will decrease when it is wet. Only two grids will be displayed when fully charged. You can disassemble the night bright screen, check the damp lines and wipe or replace them in time.
