Seamlessly-spliced display screen

Abstract

The invention relates to a splicing display technology and particularly relates to a seamlessly-spliced display screen. The seamlessly-spliced display screen comprises display screens which are spliced with one another, wherein a first linear polaroid is adhered on the surface of each display screen; the surface of each first linear polaroid is provided with an oblique cube-corner prism with a flat surface and a flat back surface; one side surface of the oblique cube-corner prism, on the same side of a splicing seam formed by splicing with the display, and the opposite surface are mutually parallel oblique surfaces; each of the parallel oblique surfaces is plated with a prism polarization light splitting film; by utilizing the prism polarization light splitting films, parallel oblique surfaces far away from the splicing seam reflect P polarized light which is emitted from the display screen and formed after passing through the first linear polaroid; light emitted by the display screen forms an image block; after reflection by the prism polarization light splitting films, the P polarized light is transmitted to the parallel oblique surfaces at the splicing seam in the oblique cube-corner prism and then reflected into eyes of a human body by the parallel oblique surfaces at the splicing seam; and the splicing seam of the display screen is covered by the image block, and therefore seamless splicing display is realized; and the seamlessly-spliced display screen is simple in structure and low in cost.

Description

technical field [0001] The invention relates to splicing display technology, in particular to a seamless splicing display screen. Background technique [0002] As a new computer input device, the touch screen is currently the simplest, most convenient and natural way of human-computer interaction. It endows multimedia with a new look and is a very attractive new multimedia interactive device. [0003] However, when a touch screen with a relatively large display size or multiple touch operations are performed simultaneously, a larger display screen is required, and now the maximum area of ​​a single display screen does not exceed 80 inches. Therefore, it is feasible to form a large-area display by splicing a single display to realize a large-area touch display. Due to the requirements of the driving circuit, production process and installation process, a certain space will be left between the display devices, so that when multiple display devices are displayed, there will i...

Problems solved by technology

Due to the requirements of the driving circuit, production process and installation process, a certain space will be left between the display devices, so that when multiple display devices are displayed, there will inevitably be a "frame" of the display screen, which will cause the screen to be 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

However, in the prior art, the seamless splicing of display screens generally requires an additional optical structure in front of the display screens, and installing a touch positioning device in front of the seamlessly spliced ​​display screens will increase the weight and thickness of the entire display device. cost increase
