AI Technical Summary

Technical Problem

The existing LED spherical screen splicing scheme at the top of the spherical surface is a sharp contraction, resulting in uneven distribution of pixel points, forming image deformation and splicing gaps, affecting the display effect.

Method used

By dividing the spherical screen into six identical arc surfaces and cutting at the same angle along the X-axis and Y-axis, n*m small cells are formed, the figure where the edges of each small cell are located and the figure where the edges of the arc surface are located. For similar graphics, ensure that pixel points are evenly arranged.

Benefits of technology

The uniformity of pixel distribution on the top of the spherical surface is achieved, image deformation and stitching gaps are avoided, and the stability and consistency of the display effect are improved.

Abstract

The invention discloses a screen segmentation method and a spherical screen, and relates to the field of special-shaped LED screens. In the prior art, a current mainstream LED dome screen splicing scheme is limited by pixel point distribution of small-spacing LEDs, zigzag arrangement is formed at the edge, obvious splicing gaps are generated after splicing, and especially at the top of a spherical surface, due to sharp contraction of a circular arc and denser pixel point distribution, an image is seriously deformed, and the splicing effect is poor. According to the technical scheme, the screen segmentation method is applied to the spherical screen and comprises the steps that a spherical surface where the spherical screen is located is segmented into six identical cambered surfaces; cutting each cambered surface along the X axis and the Y axis at the same angle by taking the center of the sphere where the cambered surface is located as a vertex to form n * m small units; the graph where the edges of the small units are located is similar to the graph where the edges of the cambered surface are located. The method is suitable for being applied to design work of the small-spacing LED spherical screen.
