Abstract
A display panel, a control method thereof, and an electronic terminal are provided. The control method includes: determining whether a display frequency of the display panel is converted in each of x frames, wherein x is a positive integer greater than or equal to 2; and in response to determining that the display frequency of the display panel is converted in each of the x frames, changing a common voltage from a first voltage gradually to a second voltage in a plurality of frames, from at least a last frame in the x frames.

A control method of a display panel, comprising:
- determining whether a display frequency of the display panel is converted during each of x frames, where x is a positive integer greater than or equal to 2;
- and
- in response to determining that the display frequency of the display panel is converted during each of the x frames, changing a common voltage from a first voltage gradually to a second voltage in a plurality of frames beginning from at least a last frame of the x frames,
- wherein a number of the plurality of frames is larger than two, and in the plurality of frames, a ratio of an absolute value of a difference value between the common voltages in every two adjacent ones of the plurality of frames and an absolute value of a difference value between the display frequencies in the every two adjacent ones of the plurality of frames is equal to a preset ratio.
A display panel, comprising:
- a controller configured to:
- determine whether a display frequency of the display panel is converted during each of x frames, wherein x is a positive integer greater than or equal to 2;
- and
- in response to determining that the display frequency of the display panel is converted during each of the x frames, change a common voltage from a first voltage gradually to a second voltage within a plurality of frames, from at least a last frame of the x frames,
- wherein a number of the plurality of frames is larger than two, and in the plurality of frames, a ratio of an absolute value of a difference value between the common voltages in every two adjacent ones of the plurality of frames and an absolute value of a difference value between the display frequencies in the every two adjacent ones of the plurality of frames is equal to a preset ratio.
An electronic terminal comprising the display panel comprising:
- a controller configured to:
- determine whether a display frequency of the display panel is converted during each of x frames, wherein x is a positive integer greater than or equal to 2;
- and
- in response to determining that the display frequency of the display panel is converted during each of the x frames, change a common voltage from a first voltage gradually to a second voltage within a plurality of frames, from at least a last frame of the x frames,
- wherein a number of the plurality of frames is larger than two, and in the plurality of frames, a ratio of an absolute value of a difference value between the common voltages in every two adjacent ones of the plurality of frames and an absolute value of a difference value between the display frequencies in the every two adjacent ones of the plurality of frames is equal to a preset ratio.
