Embodiment

[0063] like figure 1 and 13 As shown, this embodiment provides a method for forming a curved display screen, comprising the following steps:

[0064] S1: use modeling software to model and form a virtual display layer 11 in the form of a curved surface, carry out average virtual segmentation of the display layer 11 along the horizontal and vertical directions respectively, and obtain a plurality of virtual display modules 111, see Figure 2-3 In this embodiment, the spherical screen-shaped display layer 11 is taken as an example, and the display layer 11 is segmented horizontally and vertically with fixed angles θ and λ, respectively, to carry out average virtual segmentation.

[0065] Then calculate the size of each virtual display module 111, the calculation method of the size of the virtual display module 111 is as follows, see Figure 4 , define the plane where the cross-sectional circle with a diameter of D is the equatorial plane, symmetrically divide the display layer...

Abstract

The invention relates to the technical field of LED screen display, in particular to a curved-surface display screen, and a bearing framework and a forming method thereof. According to the curved-surface display screen forming method, the size of a virtual display module is mapped to the size of a materialized display module; the sizes of all the virtual display modules are scaled up or down to the plan view size of the materialized display modules in equal proportion; that is to say, the display modules for actual splicing are of a surface plate structure, the display modules of the surface plate structure are easy to machine, and the dimensional precision is easy to control; furthermore, the display modules are subjected to edge shrinking, correspondingly, an adjusting space is reservedfor two adjacent display modules, adjusting protrusions are further reserved on each edge, gaps can be prevented from being formed in the splicing process of the display modules under the condition that the machining precision is not high, adjusting bosses of the display modules with the large size are machined when the problem of over-tight installation occurs, the splicing precision can be ensured, the installation precision is effectively improved, and accumulated errors are eliminated.

Description

technical field [0001] The invention relates to the field of LED screen display, in particular to a curved display screen, a bearing structure and a forming method thereof. Background technique [0002] With the continuous development of the LED industry, in order to meet the market demand, there are more and more large-scale curved LED display screens. At present, large-scale curved LED display screens are all assembled from LED modules of the same size, and there is a flat surface after assembly. Problems such as poor precision and large gaps will eventually lead to poor display effects. For this reason, someone proposes a forming method for a large-scale curved LED screen, which includes the following steps: 1) forming a screen model; 2) defining the plane where the cross-sectional circle with a diameter of D is the equatorial plane, and going up and down from the equatorial plane Symmetrically divide the curved surface of the large spherical LED screen model into multip...
