Spherical display screen and manufacturing method thereof

Abstract

The invention discloses a spherical display screen and a manufacturing method thereof. Light-emitting pixels are distributed on a spherical surface along a spherical coordinate; based on such distribution, the light-emitting pixels are distributed on the spherical surface along curved surfaces, that is, the light-emitting pixels are distributed completely according to the expanding of the spherical surface, so that the display frame of the spherical display screen has a high resolution ratio and is undistorted, and the overall display effect is greatly improved. According to the manufacturing method of the spherical display screen, the spherical surface is divided into the curved surfaces, and the light-emitting pixels are arranged on the curved surfaces in spherical coordinate positions corresponding the spherical surface; then display module PCBs (Printed circuit boards) are manufactured and designed according to the curved surfaces; finally the display module PCBs are assembled to form a sphere, thus obtaining the spherical display screen. Through the method, the spherical display screen can be obtained quickly and is free from edges and corners; the light-emitting pixels are distributed along the curved surfaces of the spherical surface, so that the resolution ratio is high, the image display is not undistorted, and the display effect is good.

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. [0003] Therefore, the spherical display usually adopts the following methods: [0004] 1. Pixel combination method: make a surface spherical structural frame and a certain number of independent light-emitting pixels, and arrange light-emitting pixels on the spherical surface according to certain rules. This method is limited by the size of the pixel structure and cannot be made high Density high resolution display. [0005] 2. Combination method of pixel light strips: make a spherical surface structure frame and a certain number of strip-shaped light-emitting pixel light strips, and arrange pixel light strips on the sphe...

Problems solved by technology

[0004] 1. Pixel combination method: make a surface spherical structural frame and a certain number of independent light-emitting pixels, and arrange light-emitting pixels on the spherical surface according to certain rules. This method is limited by the size of the pixel structure and cannot be made high Density High Resolution Display

[0005] 2. Combination method of pixel light strips: make a spherical surface structure frame and a certain number of strip-shaped light-emitting pixel light strips, and arrange pixel light strips on the spherical surface according to horizontal latitude lines. This method is also limited by the structural size of pixel light strips. Can not be made into a high-density high-resolution display

[0007] Among the above methods of making a spherical display, the first and second are limited by the pixel structure and cannot be made into a high-resolution display. Only the third method can be used to make a high-definition and high-resolution display.

In terms of the existing technology of using the third method to make a spherical display, it is usually to use trapezoidal or triangular modules to combine and splicing the spherical surface. Do pixel sampling processing in the direction of the two poles to complete the coverage of the pixels on the spherical surface. This method can make a high-density and high-resolution spherical display, but its disadvantage is that the combination of trapezoidal or triangular modules only forms an approximate spherical surface.

The pixel points on the module are not arranged according to the spherical surface, and the display screen of the spherical display screen will be distorted, and the overall display effect will be greatly reduced. A new method is needed to solve this kind of display problem
