Top rake voltage be less than the starting point charging sub-pixel unit top rake voltage, and the tail end charging sub-pixel unit
Top rake voltage and the starting point charging sub-pixel unit top rake voltage between difference in the default value range.
9. a kind of display device, which is characterized in that the display device includes display panel, memory, processor and is stored in
On the memory and the driver of display panel that can run on the processor, the display panel includes scanning
Line, data line and sub-pixel unit, the data line are arranged along column direction, and the adjacent sub-pixel unit in left and right shares a number
According to line, the scan line is arranged along line direction, and with a line, adjacent sub-pixel unit connects different scan lines, each other with a line
The sub-pixel unit for being spaced a sub-pixel unit connects identical scan line, and the driver of the display panel is by the place
The step of reason device realizes the driving method of display panel as described below when executing:
Obtain the top rake voltage of odd column sub-pixel unit；
The target top rake voltage of even column sub-pixel unit is determined according to the top rake voltage of the odd column sub-pixel unit, it is described

Difference between the top rake voltage of column sub-pixel unit is in default value range；And
The top rake voltage of the even column sub-pixel unit is adjusted to the target top rake voltage.
10. a kind of computer readable storage medium, which is characterized in that be stored with display surface on the computer readable storage medium
The driver of the driver of plate, the display panel realizes the driving of display panel as described below when being executed by processor
The step of method:
Obtain the top rake voltage of odd column sub-pixel unit；
The target top rake voltage of even column sub-pixel unit is determined according to the top rake voltage of the odd column sub-pixel unit, it is described
Target top rake voltage is less than the top rake voltage of the odd column sub-pixel unit, and the target top rake voltage and the odd number
Difference between the top rake voltage of column sub-pixel unit is in default value range；And
The top rake voltage of the even column sub-pixel unit is adjusted to the target top rake voltage.
