Abstract
A method of controlling a display panel, a display panel, and a display device are disclosed. The display panel includes a display panel for image displays. The method of controlling the display panel includes obtaining a target grayscale area in the display area, and driving grayscales of the target grayscale area based on a desired voltage. The desired voltage is obtained by at least two times of adjustments according to historical display data of the target grayscale area. The present application is provided to improve display effects of the display panel.

A method of controlling a display panel, the display panel comprising a display area for image displays, and the method comprising:
- obtaining a target grayscale area in the display area;
- driving grayscales of the target grayscale area based on a desired voltage, comprising:
- driving the grayscales of the target grayscale area using an initial voltage to enable the target grayscale area to display a first preset image, wherein the initial voltage is a voltage set according to predetermined rules;
- enabling the first preset image to satisfy a first predetermined requirement by adjusting the initial voltage, so that the target grayscale area display a second preset image, and obtaining a driving voltage of each of the grayscales of the target grayscale area after a first adjustment process, so that a first driving voltage different from the initial voltage is obtained;
- enabling the second preset image to satisfy a second predetermined requirement by adjusting the first driving voltage of all the grayscales or some of the grayscales of the target grayscale area, and obtaining a driving voltage of each of the grayscales of the target grayscale area after a second adjustment process;
- and
- obtaining a desired voltage according to the driving voltage of each of the grayscales of the target grayscale area after the second adjustment process;
- wherein the desired voltage is obtained by at least two times of adjustments according to historical display data of the target grayscale area.
A display device, comprising:
- a display panel comprising a display area for image displays;
- and
- a processor electrically connected to the display panel;
- wherein the processor is configured to perform acts comprising:
- obtaining a target grayscale area in the display area;
- driving grayscales of the target grayscale area, and using an initial voltage set according to predetermined rules to enable the target grayscale area to display a first preset image;
- enabling the first preset image to satisfy a first predetermined requirement by adjusting the initial voltage, so that the target grayscale area display a second preset image;
- obtaining a driving voltage of each of the grayscales of the target grayscale area after a first adjustment process, so that a first driving voltage different from the initial voltage is obtained;
- enabling the second preset image to satisfy a second predetermined requirement by adjusting the first driving voltage of all the grayscales or some of the grayscales of the target grayscale area;
- obtaining a driving voltage of each of the grayscales of the target grayscale area after a second adjustment process;
- and
- obtaining a desired voltage according to the driving voltage of each of the grayscales of the target grayscale area after the second adjustment process;
- wherein the desired voltage is obtained by at least two times of adjustments according to historical display data of the target grayscale area.
