  • Patent number: 12451042
    Abstract: Provided is a method for driving a display panel, including: acquiring gamma correction data of each of the display blocks; for each pixel in the display panel, determining, based on the gamma correction data of a first display block where the pixel is located, a first correction voltage corresponding to a to-be-displayed target gray scale of the pixel; determining, based on the gamma correction data of at least one second display block adjacent to the first display block, at least one second correction voltage corresponding to the target gray scale; determining a gamma voltage of the pixel based on the first correction voltage, the at least one second correction voltage, and a position of the pixel in the display panel; and driving, based on the gamma voltage, the pixel to display the target gray scale.

  • Publication number: 20220005393
    Abstract: The present disclosure provides a method and a device for determining a pixel compensation value, an electronic device and a storage medium. The method includes: enabling a pixel to display at three test gray scales respectively, and obtaining an actual luminosity of the pixel at each test gray scale; calculating compensation values of the pixel at the three test gray scales according to actual luminosities and standard luminosities of the pixel at the three test gray scales respectively, wherein the compensation value of the pixel at any gray scale is a gray scale which can enable the actual luminosity of the pixel to be equal to the standard luminosity of the pixel at the gray scale; calculating standard coefficients Gain1, Gain2 and Offset according to a specific formula; and calculating the compensation value y of the pixel at the gray scale x according to a specific formula.
