Abstract: The present disclosure discloses an image processing and display method, apparatus and device, and a computer storage medium thereof, belonging to the field of display technologies. The method includes: transmitting a first image of a first resolution to a display component at a first frequency in the case that the mode information indicates a first mode, wherein the first image is formed by splicing a plurality of sub-images of a second resolution; and transmitting a second image of the first resolution to the display component at a third frequency in the case that the mode information indicates a second mode, wherein n second images form a frame of image of the display component. The present disclosure provides two types of display modes. In one mode, a first image composed of a plurality of sub-images can be transmitted to a display component, such that the display component displays these sub-images at a higher frequency. In another mode, a frame of image can be transmitted to the display component a plurality of times. The display methods are flexible, which solves the problem of low flexibility in the methods in the related technology, and achieves the effect of improving the flexibility of the image display method.
