Spherical display screen and manufacturing method thereof

Abstract

The invention discloses a spherical display screen and a manufacturing method thereof. The method comprises the following steps: according to the Euler's formula in space, obtaining 12 pentagons and 20 hexagons which can form a 32-face body inscribed in a spherical surface; then causing one points on the spherical surfaces corresponding to the pentagons and the hexagons to be connected with the end points of corresponding pentagons and hexagons to form pentagonal pyramids and hexagonal pyramids; according to the side faces of the pentagonal pyramids and the hexagonal pyramids, manufacturing pentagonal display modules and hexagonal display modules; finally assembling 12 pentagonal display modules and 20 hexagonal display modules into a spherical screen similar with a sphere. Therefore, when the display modules are designed, at most 32 display modules are designed, the product-design period is greatly shortened, and a lot of design labor resources are reduced. In the spherical display screen manufactured with the method, glowing pixel points can be uniformly arranged on each triangular side face of the pentagonal display modules and the hexagonal display modules. The spherical display screen has the advantages of simple structure, good pictures of displayed images and small distortion.

Description

technical field [0001] The invention relates to the field of display screens, in particular to a spherical display screen and a manufacturing method thereof. Background technique [0002] A ball is a geometric body with no edges and corners on the surface, so the spherical surface is a special curved surface, and it is impossible to expand it on a plane. At present, the spherical high-resolution display usually adopts the trapezoidal module method to make a surface spherical structural frame, and then make a series of trapezoidal light-emitting modules of different shapes and specifications, and use these trapezoidal modules of different specifications to assemble on the spherical surface. , and these polyhedrons form an approximate spherical display. [0003] In the method of making a spherical display with a trapezoidal module, the pixels on the module are arranged in the horizontal or vertical direction, and pixel sampling is performed from the equator line with the larg...

AI Technical Summary

Problems solved by technology

This method can be made into a high-density and high-resolution spherical display, but its disadvantage is that the assembly of trapezoidal modules only forms an approximate spherical surface

The pixel points on the module are arranged according to the longitude and latitude lines, not according to the spherical surface. The spherical display screen pixels are unevenly distributed on the spherical surface. If the pixels are selected to process the display screen, the screen will be distorted and the overall display effect will be greatly reduced.

[0004] The trapezoidal module method is generally divided into several trapezoidal modules according to the latitude and longitude of the spherical surface. The modules used in each latitude are different from those used in other latitudes. Therefore, it is necessary to divide them into several different modules according to the diameter of the sphere. For latitude modules, many kinds of modules need to be designed for the entire sphere, and the larger the diameter of the sphere, the more specifications the trapezoidal modules are divided into, which makes the product design cycle longer and consumes a lot of design manpower
