Abstract: A display panel and a preparation method therefor, and a display device are provided. The display panel includes first and second substrates oppositely provided, and a polymer-stabilized liquid crystal layer; multiple sub-pixels include at least one first sub-pixel emitting light from a side of the second substrate away from the first substrate and at least one second sub-pixel emitting light from a side of the first substrate away from the second substrate; the first substrate in a first sub-pixel has a first shielding pattern, and an orthographic projection of the pixel electrode therein on a display panel plane is within that of the first shielding pattern on the first substrate; the second substrate in a second sub-pixel has a second shielding pattern, and an orthographic projection of the pixel electrode therein on the display panel plane is within that of the second shielding pattern on the second substrate.

Abstract: A method of digital image combination for multiple channels with multiple sets and a bus interface which includes an image-processing unit for m-channel sub-images, an image-processing unit for n-set combining images, n-set video data buses, address and control buses and a pixel data access control and bus switching logic module. A bus strobe signal controls m-channel sub-images pixel data outputting to one set of the n video data buses at a specific moment. The n sets of image-processing units for combining images combine the sub-images pixel data on the video data buses of n sets to form n integral image data. The method can be used in the multimedia image communication system and image editing system for raising the multiple image-processing capabilities.
