Display device for eliminating display frame

Abstract

The invention relates to the field of display devices, and particularly relates to a display device for eliminating a display frame. The display device comprises a display panel, wherein the display panel is divided into a center display area, an edge display area and a frame area, an optical system is arranged on the surface of the display panel and provided with one or a plurality of direct light structures positioned on the surface of the center display area and one or a plurality of periscope structures positioned on the surface of the edge display area, light which exits from the center display area directly penetrates through the direct light structures to exit, and light which exits from the edge display area is offset to the direction of the frame area through the periscope structures and then exits. According to the display device, the periscope principle is utilized to set the periscope structures, and the periscope structures are arranged in the edge display area of the display panel, so that a part of light which exits from the edge display area is offset to the frame area, thereby transferring a part of the pixel of the edge display area of the display panel to the frame area, so as to achieve the effect of eliminating the frame and realize seamless splicing of the display panel.

Description

Technical field [0001] The present invention relates to the field of display devices, and more specifically, to a display device that eliminates a display frame. Background technique [0002] With the rapid development of large-size LCD panels, LCD displays have gradually become the mainstream of display technology due to their ultra-thin, light weight, non-radiation, and stable performance. At present, large-size LCDs can reach 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] Existing LCD panels due to the surrounding circuit wiring and packaging requirements, there is inevitably an undisplayable area around the displayed image.

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.
