Spherical dot matrix display screen and spherical surface dot matrix display screen

Abstract

The invention provides a spherical dot matrix display screen. The spherical dot matrix display screen comprises six quadrilateral quasi-spherical surface screens, wherein the quadrilateral quasi-spherical surface screens are same in shape and size, every two adjacent quadrilateral quasi-spherical surface screens are spliced, and the angular vertexes of the quadrilateral quasi-spherical surface screens are arranged on the same spherical surface; each quadrilateral quasi-spherical surface screen is divided by n equal-division longitude lines and m latitude lines into n*m positions where quadrilateral plane display panels are installed, and therefore the varieties of the quadrilateral plane display panels which are matched and designed are few, and the quadrilateral plane display panels are applicable to batch manufacturing, maintenance and replacement. The operation that the quadrilateral plane display panels which are installed in a bent mode on angle end points on the same latitude line are pressed to be attached to the spherical surface can be easily carried out. Each quadrilateral plane display panel comprises a face shield, a PCB, a bottom shell, a waterproof sealing ring and fixing screws, wherein the lamp surface of the PCB is filled with waterproof glue, and the quadrilateral plane display panels are applicable to outdoor installation and application of the spherical dot matrix display screen or a spherical surface dot matrix display screen. The spherical surface dot matrix display screen can be formed in a mode that a portion of the spherical dot matrix display screen is cut as needed.

Description

technical field [0001] The invention relates to a structure of a dot matrix display screen, in particular to a spherical dot matrix display screen composed of a plane display panel and a structure of a spherical dot matrix display screen composed of a plane display board. Background technique [0002] Dot matrix display screens such as LED display screens have been widely used. A typical dot matrix display has a rectangular planar structure. At present, there is a demand for spherical and spherical dot matrix displays in the market. How to use a planar dot matrix display to construct a dot matrix display that is as close to a spherical or spherical surface as possible and has a simple structure and is easy to manufacture and maintain is a problem that technicians try to solve. [0003] Patent document CN103871329A discloses a spherical display screen and a spherical display screen composed of a flat display board, which is composed of 6 adjacently spliced ​​quadrangular sp...

Problems solved by technology

Of course, n and m cannot be simply reduced to reduce the number of divisions, otherwise it will reduce the degree to which the spherical display and spherical display composed of flat display panels are close to spherical or spherical

How to obtain fewer types of flat display panels under a certain number of divisions, the patent document CN103871329A and other existing documents do not involve and solve this problem
