  • Publication number: 20240412705
    Abstract: A display device and a panel drive circuit thereof, and a method for charge bleed-off are disclosed, relating to the field of display technologies. The panel drive circuit includes a panel control circuit and a display drive circuit. In the case that a display panel is turned off, the panel control circuit transmits at least one of a display drive signal and a charge bleed-off signal sequentially to the display drive circuit before a potential of a power supply signal drops to less than a potential threshold, such that the display drive circuit sequentially performs at least one of controlling the display panel to display a second picture that is monochrome and bleeding off charges in advance.

  • Publication number: 20220172688
    Abstract: The present disclosure provides a display method, a computer storage medium, and a display device. The display method includes: detecting a frame image including a still image; accumulating a retention time of the still image in the frame image, the retention time is a time for uninterruptedly displaying the still image; determining whether the accumulated retention time is greater than a threshold value; sequentially shifting data of the frame image by n rows in response to that the accumulated retention time is greater than the threshold value, the threshold value is an accumulated value of the retention time when a line afterimage begins to appear on the still image; a row direction of the n rows is a scanning direction of the frame image; wherein 1?n?3N/4, N is a total number of rows scanned for one frame image, n is an integer, and 3N/4 is rounded to an integer.
