Abstract: A control device includes a memory and a processor. The memory is configured to store a time comparison table. The processor is configured to determine whether a displayed image is a still image. When the displayed image is determined to be a still image, the time comparison table is queried for a corresponding still image judgment duration according to an average pixel level and a type of the still image.

Abstract: Provided is a method for sensing pixel internal data in a display device. The method includes: sensing pixel internal data for each line of pixel units to determine column sequence numbers of suspected abnormal pixel units in the line of pixel units; determining, based on a number of the suspected abnormal pixel units of each column sequence number in the at least three lines of pixel units, whether a sensing signal line corresponding to the column sequence number is an abnormal sensing signal line; and in a case that there is at least one abnormal sensing signal line, replacing pixel internal data of a column of pixel units corresponding to each abnormal sensing signal line with pixel internal data of at least one column of pixel units adjacent to the abnormal sensing signal line each time the pixel internal data of all pixel units is sensed.
