Method and device for eliminating splicing seams among spliced display screens, and spliced display system

Abstract

The invention discloses a method and device for eliminating splicing seams among spliced display screens, and a spliced display system. The method comprises the following steps of: dividing a preset number of blocks of zoned areas in an image display area of the spliced display screens according to a preset dividing mode, wherein the sum of the preset number of blocks of zoned areas is equal to the area of a frame among the spliced display screens; dividing an image display period into M sub-periods; in the M sub-periods, displaying an image in an image display area or a zoned area corresponding to the sub-periods according to a preset image display mode; and moving each spliced display screen according to a preset moving mode corresponding to the sub-periods so as to overlap the moved zoned area with the position of the frame to be covered corresponding to an unmoved state. By using the technical scheme of the invention, images displayed in different areas can be displayed on the spliced display screens at the same time without frames, so that the splicing seams among the spliced display screens are eliminated and high-quality seamless splicing display is realized.

Description

technical field [0001] The invention relates to a method for eliminating joints between spliced ​​display screens, a device for eliminating joints between spliced ​​display screens and a spliced ​​display system. Background technique [0002] With the society's increasing demand for super-large-screen display, and due to the limitation of the size of each display device itself, it is a feasible and increasingly mature large-screen display method to realize super-large-screen display by splicing various display devices, and the application In various applications, such as outdoor advertising, stadiums, and control room applications such as power dispatching and subway dispatching. However, due to the requirements of the driving circuit, production process and installation process, it is inevitable to leave a certain space, so when multiple display devices are displayed, there will inevitably be a "frame" of the display screen, resulting in the screen being blocked.

However, due to the requirements of the driving circuit, production process and installation process, it is inevitable to leave a certain space, so when multiple display devices are displayed, there will inevitably be a "frame" of the display screen, resulting in the screen being blocked. Segmentation destroys the continuity and integrity of the image, seriously affects the overall effect of the splicing display screen, and cannot achieve high-quality seamless splicing display
