Embodiment 1

[0061] A spherical display, including an upper hemisphere and a lower hemisphere, the upper hemisphere is divided into layered surface modules according to latitude, and the lower hemisphere is divided into layered surface modules according to latitude, and the arc length of the curved surface modules of the upper hemisphere starts from the first layer The arc length of the curved surface module in the lower hemisphere decreases in turn from the 1st floor to the 7th floor. Each layer of curved surface module is composed of 60*2 boxes spliced ​​into a curved surface structure. Each box The body is spliced ​​by 4 triangular modules, and is an isosceles triangle with a curved surface. The diameter of the spherical display screen is 15240 mm, and its spherical surface is divided into 8640 triangular modules with equal arc heights. The arc height of the triangular module 1 is 400mm;

[0062] The triangular module includes a base plate, a PCB board and a mask, the base plate and the...

Abstract

The invention discloses a spherical display screen, which comprises an upper hemisphere and a lower hemisphere, the upper hemisphere is divided into a layers of curved surface modules according to latitude, the lower hemisphere is divided into b layers of curved surface modules according to latitude, a is greater than 3 and b is greater than 3, the arc lengths of the curved surface modules of theupper hemisphere are sequentially decreased from the first layer to the a layer, and the arc lengths of the curved surface modules of the lower hemisphere are sequentially decreased from the first layer to the b layer. Each layer of curved surface module is divided into c units according to longitude, c is larger than 3, each unit comprises at least two box bodies, each box body is formed by splicing a plurality of triangular modules and is in a curved surface isosceles triangle shape, each triangular module comprises a bottom plate, a PCB and a mask, and the bottom plate and the mask are of acurved surface structure. The spherical display screen is divided into a plurality of curved isosceles triangles according to the longitude and latitude directions, the logic is simple, the installation is convenient, the spherical radian is closer to the theoretical radian, and the sphere is rounder.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to a spherical display screen. Background technique [0002] LED spherical display is a kind of creative LED display, which has the characteristics of multiple display splitting and uniform technical display with high-definition and undistorted images. It is mainly used in museums, science and technology museums, exhibition halls, decorative lighting projects and other fields. [0003] For the existing watermelon rind spherical screen, see figure 1 , it is composed of watermelon skin-like PCB. Its advantage is that the structure is intuitive, and there are fewer types of PCBs. Its fatal disadvantage is that the north and south poles (that is, north of 45° north latitude and south of 45° south latitude) cannot play images normally. , so the screen utilization rate is too low or the image distortion is serious. The reason is that the pixel points of all current image sou...
