Any-arc-angle excircle-spherical-surface-displaying seamless display screen

Abstract

The invention discloses an any-arc-angle excircle-spherical-surface-displaying seamless display screen, and belongs to the technical field of VR displaying. The any-arc-angle excircle-spherical-surface-displaying seamless display screen comprises a pentagonal outer spherical surface splicing unit, a hexagonal outer spherical surface splicing unit, outer-spherical-surface-splicing-unit frame carriers and an outer-spherical-surface-splicing-unit fixing and supporting frame. The any-arc-angle excircle-spherical-surface-displaying seamless display screen has the advantages that due to excircle spherical surface displaying, the highlighting feeling and the decorous feeling of images are improved; particularly, when the any-arc-angle excircle-spherical-surface-displaying seamless display screen is used for AR scenarios, movement senses and changes can be given to static seal scenes, and the unexpected shocking effect can be generated for a person. The any-arc-angle excircle-spherical-surface-displaying seamless display screen can be widely applied to teaching, AR landscape architecture, exhibitions, showing, science and technology museums and other places.

Description

technical field [0001] The invention belongs to the technical field of VR display, and in particular provides a seamless display screen with an outer spherical display with any arc angle. the use of. Background technique [0002] The outer spherical display can not only make the image obtain a wide viewing angle, but also make the image stand out, and can also truly reproduce the outer spherical image, such as a globe for teaching. In addition to teaching, the greatest use of the outer spherical display lies in the application of AR display. For example: used in AR garden landscapes, the outer spherical display can instantly highlight certain images, giving people a special shock. Most of the existing outer spherical displays are spliced ​​with tiny LED modules with a large pixel pitch. It is not only like a small mosaic when viewed at a close distance, but also when assembled into an outer spherical display, there will be gaps between the modules, and the gaps will produc...

Problems solved by technology

Most of the existing outer spherical displays are spliced ​​with tiny LED modules with a large pixel pitch. It is not only like a small mosaic when viewed at a close distance, but also when assembled into an outer spherical display, there will be gaps between the modules, and the gaps will produce black. Seams, black seams splitting the picture will make people feel visually uncomfortable

It is well known that the cylindrical curved surface display can be realized through the bending of the screen by virtue of the bendability of the screen, but the spherical display is difficult to realize through the conventional simple method, because the existing display technology, whether it is projection or flexible flat display , it is difficult to realize outer spherical display
