Seamless splicing display device

Abstract

The invention discloses a seamless splicing display device, and relates to the technical field of display devices. The seamless splicing display device is provided to eliminate splicing seams visually and improve the display effect of a display device. The seamless splicing display device comprises at least two adjacent spliced display screens. The splicing positions of every two adjacent display screens are provided with splicing seams respectively. The seamless splicing display device further comprises lens bodies. The lens bodies are provided with incident surfaces, end surfaces and emergent surfaces, the emergent faces are provided with protruded arc surfaces, the end surfaces are perpendicular to the incident surfaces, the incident surfaces are connected with the arc surfaces through the end surfaces, the incident surfaces are parallel to the surfaces of the display screens, the lens bodies cover the surfaces of the display screens and the splicing seams through the incident surfaces, light rays transmitted out by the surfaces of the display screens covered by the lens bodies enter the lens bodies through the incident surfaces and are transmitted out from the emergent surfaces, the out-transmitting direction of light rays transmitted out from the intersected edge of the arc surfaces and the end surfaces is perpendicular to the surfaces of splicing seams, and the splicing seams covered by the incident surfaces are eliminated visually. The seamless splicing display device can be used for splicing screens.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a seamless splicing display device. Background technique [0002] The splicing screen is a large-area display formed by splicing multiple display screens together, also known as a splicing wall. The splicing screen has the characteristics of ultra-high resolution and super-large screen display. Due to the presence of borders or non-display areas on the display screens, there are black seams between adjacent display screens, which seriously affects the display effect. The mainstream method of eliminating seams in the existing seamless stitching technology is image enlargement, and the specific structure is as follows: Figure 1 ~ Figure 3 As shown, the lens body 03 is covered on the joint 02 and the display screen 01. The lens body 03 includes an incident surface 031 and an exit surface. The incident surface 031 is a plane, and the lens body 03 covers the display ...

Problems solved by technology

[0003] However, the seamless splicing technology of the prior art cannot completely eliminate the splicing seam

The specific reasons are as follows: figure 1 As shown, the lens body 03 covers the joint 02 and the display screen 01, point C is the closest point on the display screen 01 to the joint 02, the light emitted from point C is the first to be emitted perpendicular to the joint 02, point D It is the exit point of the light emitted from point C after passing through the lens body 03. If the outgoing light of light CD is just perpendicular to the seam 02, and the vertical point of point D on the seam 02 is B, then when looking directly, AB is still It is black stitching, which cannot be completely eliminated visually. 02
