Cylindrical-surface spliced spherical dot-matrix display screen

Abstract

The invention provides a cylindrical-surface spliced spherical dot-matrix display screen. The display screen comprises display panels which are divided according to longitude lines and latitude lines and adjacently spliced on a spherical surface, the display panels are each shaped like a cylindrical surface which is bent along the spherical surface in the longitudinal direction, and spliced latitudinal edge lines of the display panels on the spherical surface in the bending direction are intersecting lines. Fine-tuning studs are arranged between the display panels and installation beams, and splicing gaps of the display panels can be reduced by properly selecting the length of the fine-tuning studs. The cylindrical-surface spliced spherical dot-matrix display screen has the advantages that the bent planar display panels are mutually spliced on the spherical surface in the shapes of cylindrical surfaces in an intersecting line mode, and splicing of the display panels can be more compact; by means of the fine-tuning studs, the display panel splicing gaps caused by manufacturing errors are reduced; in this way, the precisely manufactured watermelon-peel type spherical dot-matrix display screen is compact in appearance splicing, good in appearance effect, simple in structure and easy to manufacture and maintain.

Description

technical field [0001] The invention relates to a structure of a dot-matrix display screen, in particular to a structure of a spherical dot-matrix display screen and a spherical dot-matrix display screen formed by splicing cylindrical display panels. Background technique [0002] Spherical dot matrix displays such as spherical LED displays have been used. At present, the common spherical LED display screen, its display board is generally divided according to the warp and latitude and then spliced ​​into a spherical surface, which is commonly called "watermelon skin" type spherical screen in the industry. Many documents, for example, patent documents CN201812452U, CN102968934A and CN103310712A describe different implementations of such spherical LED display screens. However, if the display board adopts a common flat PCB board (printed circuit board), it is difficult to process it into the shape of "ball petal", "melon scoop" or "spherical surface". The literature in the ind...

AI Technical Summary

Problems solved by technology

However, if the display board adopts a general-purpose flat PCB board (printed circuit board), it is difficult to process it into the shape of "ball petal", "melon scoop" or "spherical surface"

The literature in the industry hardly involves or clearly describes the marginal relationship of splicing flat display panels on the spherical surface, nor does it propose a satisfactory technology for tightly splicing flat display panels on the "watermelon rind" spherical surface, resulting in the impossibility of precise manufacturing in practice. The splicing gap of the display panel is relatively large

[0003] On the other hand, if the flat display panel is directly spliced ​​on the spherical surface, the flat display panel on the spherical surface will look like fish scales, resulting in poor appearance of the spherical display
