1. A self-monitoring method of a display, comprising:
inputting a first image test signal, wherein the first image test signal comprises a predetermined image test signal, and the first image test signal comprises playing signals of at least two frames of test image that are played in turn by switching;
acquiring a display parameter of the predetermined image test signal of the first image test signal;
dividing each frame of image of at least two frames of image outputted, based on the first image test signal, by the display, into a plurality of areas respectively, wherein the plurality of areas of each frame of image of the at least two frames of image comprise a predetermined area corresponding to the predetermined image test signal and a remaining area excluding the predetermined area in each frame of image, and the predetermined image test signal is a dynamic test signal corresponding to the at least two frames of test image of the first image test signal to be played in turn;
acquiring a first display parameter of the predetermined area of each frame of image of the outputted at least two frames of image, wherein the predetermined area of each frame of image of the at least two frames of image corresponds to a corresponding first display parameter;
comparing the display parameter of the predetermined image test signal with the first display parameter, and determining whether or not an image displayed by the display is matched with the first image test signal so as to acquire a first match result; and
determining whether or not display abnormality presents in the display based on the first match result.
