The present application claims priority of a China patent application No. 202110199518.2 filed with the China National Intellectual Property Administration on Feb. 22, 2021, titled “MULTI-SCREEN AND DISPLAY DEVICE”, the contents of which are incorporated in the present application by reference in its entirety.
The present application relates to a field of display technologies, especially to a multi-screen and a display device.
With widespread display technologies, a demand for large-size display screens is also growing. At present, it is difficult for a size of a single display screen to exceed 80 inches. Therefore, a multi-screen has become a feasible way to achieve large-size displays.
The multi-screen splices display screens of smaller sizes in an array to form a display screen of a larger size. Therefore, a certain number of display screens can be selected according to actual needs to be spliced into large screens of different sizes to meet different application scenarios. Furthermore, multi-screen will form a splicing gap at a spliced portion of two display screens, and a width of the splicing gap is a sum of frame widths of the two display screens. Limited by characteristics of a structure of the display screens, a frame of the display screens has no display function. Therefore, a complete display image of the multi-screen would be split by the splicing gap, wherein the larger the width of the splicing gap is, the greater the splitting effect on the display image is, and the worse the display quality of multi-screen is.
