Claim 5:
6. An electronic device, comprising a processor, a memory coupled to the processor and a display panel coupled to the processor, wherein the processor is configured to: obtain an image frame to be displayed; determine whether pixel data in the image frame to be displayed is lost; and use preset replacement data as data of target pixels in the image frame to be displayed, in response to determining that the pixel data in the image frame to be displayed is lost; the memory is configured to store image frames to be displayed; and the display panel is configured to display image frames to be displayed, wherein the image frame to be displayed includes M pixel arrays, and M is an integer greater than 1; and
the processor is configured to determine whether the pixel data in the image frame to be displayed is lost includes: the processor is configured to determine whether pixel data in each of the M pixel arrays is lost, wherein the processor is configured to determine whether the pixel data in each pixel array is lost includes the processor is further configured to:
check a cyclic redundancy check (CRC) code in data of each row of pixels in the pixel array;
determine whether a ratio of a number of first pixel rows to a number of second pixel rows in a pixel array is greater than or equal to a first threshold value, wherein the number of first pixel rows is a number of pixel rows that fail to pass the CRC code check in the pixel array, and the number of second pixel rows is a total number of pixel rows in the pixel array; and
determine that the pixel data in the pixel array is lost in response to determining that the ratio of the number of the first pixel rows to the number of the second pixel rows in the pixel array is greater than or equal to the first threshold value, so as to determine that the pixel data in the image frame to be displayed is lost.
