A display device that eliminates the display frame

Abstract

The present invention relates to the field of display devices, and more particularly, to a display device that eliminates display frames. It includes a display panel, the display panel is divided into a central display area, an edge display area and a frame area, and the surface of the display panel is provided with an optical system, and the optical system is provided with one or more direct light guides located on the surface of the central display area. structure and one or more periscope structures located on the surface of the edge display area; the light emitted from the central display area directly passes through the straight light guide structure; The present invention uses the principle of a periscope to set a periscope structure, and places the periscope structure in the edge display area of ​​the display panel, so that part of the light emitted from the edge display area is shifted to the frame area, thereby transferring some pixels in the edge display area of ​​the display panel to the frame area , to achieve the effect of eliminating the frame, so as to realize the seamless splicing of the display panel.

Problems solved by technology

[0002] With the rapid development of large-size LCD panels, LCD displays have gradually become the mainstream of display technology due to their advantages such as ultra-thin, light weight, no radiation, and stable performance. Currently, large-size LCDs can be 80 inches to 100 inches, but It is still difficult to meet the needs of some occasions (such as monitoring, scheduling, etc.), and the yield rate of its super-large LCD panel is difficult to guarantee

[0003] Due to the needs of the surrounding circuit wiring and packaging, the existing LCD panel inevitably has an undisplayable area around the display image. This undisplayable difference is called a frame. The existence of the frame causes the screen to be divided during LCD splicing and destroys the image. continuity and integrity, which seriously affects the splicing effect

At present, many LCD panel manufacturers have been working hard to reduce the frame width of LCD panels, but they still cannot achieve zero frame and realize seamless splicing in the true sense.
