  • Patent number: 11380255
    Abstract: An optical compensation method for a display panel, an optical compensation device for a display panel, a display method for a display panel, a display device, and a storage medium are disclosed. The optical compensation method for a display panel includes: acquiring a pre-stored compensation parameter of the display panel; acquiring a current brightness level of the display panel; adjusting the pre-stored compensation parameter based on the current brightness level to obtain an adjusted compensation parameter; and compensating a display data signal of the display panel based on the adjusted compensation parameter.
    Type: Grant

  • Patent number: 11217146
    Abstract: A gray-level compensation method and apparatus, a display device and a computer storage medium are provided, which belong to the field of display technology. The method includes: acquiring an initial gray-level value of a target pixel; determining an actual luminance offset of the target pixel based on the initial gray-level value, where different initial gray-level values within a specified threshold range correspond to different actual luminance offsets; and performing a gray-level compensation on the target pixel based on the actual luminance offset. The actual luminance offset is determined based on the initial gray-level value of the target pixel, and since the different initial gray-level values within the specified threshold range correspond to the different actual luminance offsets, flexibility of gray-level compensation performed on the pixel is improved.

  • Patent number: 10939082
    Abstract: The present disclosure provides a processor, a display driving circuit, and an electronic device. The processor includes: a memory being divided into a first part that stores correction data for correcting an image signal, a second part that stores data of an image signal to be displayed, and a third part that stores data of an application to be executed; and an output port configured to transmit the data of the image signal and the correction data stored in the memory to an external display driving circuit, separately.
