1. A display control method, comprising:
performing a splitting processing on a source video stream of a display panel in response to a multi-path display control instruction, to obtain a plurality of video sub-streams the same as each other;
acquiring a processing parameter corresponding to each video sub-stream, and processing the video sub-stream according to the processing parameter; and
performing a tiling and merging operation on the processed video sub-streams to obtain an output video stream, and outputting the output video stream to the display panel for displaying,
the method further comprises:
before performing the tiling and merging operation on the processed video sub-streams to obtain the output video stream, performing a difference analysis on at least two of the processed video sub-streams in pairs according to a preset second analysis item, wherein the second analysis item comprises at least one of a pixel value difference analysis, a pixel gray value difference analysis, and a pixel gradient characteristic value difference analysis;
after performing the difference analysis on at least two of the processed video sub-streams in pairs according to the preset second analysis item, marking pixels satisfying a preset marking condition in an On Screen Display manner according to the difference analysis result, wherein the marking condition is that a difference value between any two pixels subjected to the difference analysis is greater than a preset difference threshold.
