  • Display method and display device of display panel
    Patent number: 12183255
    Abstract: A display method of a display panel includes determining whether the display panel is in a frequency conversion state, if the display panel is in a frequency conversion state, acquiring a first frequency and a second frequency corresponding to two adjacent frames consecutively for multiple times, determining whether the display panel is in a first display mode according to a difference between the first frequency and the second frequency obtained multiple times, and if the display panel is in the first display mode, turn off a brightness adjustment function of the display panel.
    Type: Grant

  • Driving method for display panel, brightness compensation device, and display device
    Patent number: 12165614
    Abstract: A driving method for a display panel includes: obtaining a change range of a refresh frequency difference of the display panel within a preset duration; obtaining a current refresh frequency of the display panel in response to determining that an upper limit of the change range of the refresh frequency difference is less than a preset refresh frequency difference; obtaining a number of display frames in response to determining that the current refresh frequency of the display panel is less than a reference refresh frequency; and performing brightness compensation on the display panel in response to determining that the number of display frames is greater than or equal to a preset number of frames.
