Method for determining overdrive voltage, display panel and computer readable storage medium

A display panel comprising a memory and at least one processor, the memory storing computer-executable instructions executable by the at least one processor, wherein when the computer-executable instructions are executed by the at least one processor, the at least one processor is caused to perform the following operations:

• determining a gray scale value of a pixel to be displayed of a current display picture and a picture type of the current display picture;
• determining a target refresh rate according to the picture type;
• and
• determining a target overdrive voltage of the pixel to be displayed according to the target refresh rate and the gray scale value of the pixel to be displayed, the target refresh rate and the target overdrive voltage being positively correlated;
• wherein the operation of determining a picture type of the current display picture comprises:
• acquiring a previous display picture frame;
• determining a second pixel of the previous display picture frame corresponding to a first pixel of the current display picture, and comparing a pixel value of the first pixel with a pixel value of the second pixel;
• determining that the current display picture is a static picture according to the picture type when a number of first pixels whose pixel values are same as pixel values of corresponding second pixels is greater than a first preset number;
• and
• determining that the current display picture is a dynamic picture when a number of first pixels whose pixel values are different from pixel values of corresponding second pixels is greater than a second preset number.

A non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium stores computer-executable instructions executable by at least one processor, when the computer-executable instructions are executed by the at least one processor, the at least one processor is caused to perform the following operations:

• determining a gray scale value of a pixel to be displayed of a current display picture and a picture type of the current display picture;
• determining a target refresh rate according to the picture type;
• and
• determining a target overdrive voltage of the pixel to be displayed according to the target refresh rate and the gray scale value of the pixel to be displayed, the target refresh rate and the target overdrive voltage being positively correlated;
• wherein the operation of determining a picture type of the current display picture comprises:
• acquiring a previous display picture frame;
• determining a second pixel of the previous display picture frame corresponding to a first pixel of the current display picture, and comparing a pixel value of the first pixel with a pixel value of the second pixel;
• determining that the current display picture is a static picture according to the picture type when a number of first pixels whose pixel values are same as pixel values of corresponding second pixels is greater than a first preset number;
• and
• determining that the current display picture is a dynamic picture when a number of first pixels whose pixel values are different from pixel values of corresponding second pixels is greater than a second preset number.
