Spherical display screen

Abstract

The invention discloses a spherical display screen. The spherical display screen comprises a support, multiple installation units, multiple connecting frames and multiple LED modules; each installation unit comprises six first isosceles triangle box bodies and three second isosceles triangle box bodies, wherein the six first isosceles triangle box bodies are spliced by adjoining waist edges to form a hexagonal assembly, the bottom edges of the second isosceles triangle box bodies are hinged to the bottom edges of three first isosceles triangle box bodies in the hexagonal assembly respectively, and the three end points of each first isosceles triangle box body and the three end points of each second isosceles triangle box body are located in the same spherical surface; all the installation units are in one-to-one correspondence with the connecting frames and are fixed to the spherical periphery of the support through the corresponding connecting frames to form a sphere, and all the installation units surround the spherical surface in the latitude direction of the spherical surface; the LED modules are attached to the outer surfaces of the first isosceles triangle box bodies and the outer surfaces of the second isosceles triangle box bodies in a one-to-one correspondence mode. The spherical display screen is easy to produce, capable of being assembled easily, good in display effect and low in cost.

Description

technical field [0001] The invention relates to the field of display screens, in particular to spherical display screens. Background technique [0002] The spherical display belongs to the category of special-shaped screens, which can bring a 360-degree visual impact to the audience. The modules or cabinets need to be connected and fixed in a circular arc shape to form a ball, and the fixed steel frame inside needs to be designed. At present, the common spherical display screen is generally a watermelon ball screen (such as figure 1 shown), football screen (such as figure 2 shown), six-sided spherical screen (such as image 3 As shown), there are four kinds of spherical display screens, dot matrix screen. However, the disadvantage of the watermelon ball screen is that the pixels of the north and south poles cannot be evenly distributed; the disadvantage of the football screen is that there are many types of display modules, which is not conducive to production and assembl...

At present, the common spherical display screen is generally a watermelon ball screen (such as figure 1 shown), football screen (such as figure 2 shown), six-sided spherical screen (such as image 3 As shown), there are four kinds of spherical display screens, dot matrix screen. However, the disadvantage of the watermelon ball screen is that the pixels of the north and south poles cannot be evenly distributed; the disadvantage of the football screen is that there are many types of display modules, which is not conducive to production and assembly. It is very troublesome to write software to display on different display modules; the disadvantage of the six-sided spherical screen is that its fixed structure is not easy to produce, and the display effect is poor; the disadvantage of the dot matrix screen is that the structure of the fixed module or the cabinet is not easy to produce
