Spherical LED (Light-Emitting Diode) display device

Abstract

The invention relates to a spherical LED (Light-Emitting Diode) display device which comprises a display screen and a substrate, wherein the bottom of the display screen is fixed on the substrate; the display screen is a hollow spherical body which is defined by mutually connecting multiple arc-shaped LED display modules along a longitude line direction and a latitude line direction through connecting plates, wherein the bottom of the hollow spherical body is planar; and the top of the display screen is provided with an opening. The spherical LED display device has the advantages that the spherical LED display screen has a round display screen appearance and multi-azimuth view angles; the image display is coherent and free from chromatic aberration, the inner space is large, the structural stability is good, and the disassembly, assembly and transport are convenient; and the large-scale stage performance requirements and indoor and outfield use requirements can be met.

Description

technical field [0001] The invention relates to the field of LED display equipment, in particular to a spherical LED display device. Background technique [0002] LED display is a new type of photoelectric display product developed in the world in the late 1980s. With the characteristics of high reliability, long service life, strong environmental adaptability, high cost performance, and low cost of use, it has quickly become the mainstream product of flat panel display. [0003] At present, most of the LED display screens are flat products with a single viewing angle, and correspondingly, the displayed text or patterns are relatively monotonous, which cannot meet the needs when displaying some special images. [0004] In order to overcome the deficiencies of flat LED display screens, more and more spherical LED display devices have appeared.

AI Technical Summary

Problems solved by technology

[0003] At present, most of the LED display screens are still flat products, with a single viewing angle, and correspondingly, the displayed text or patterns are relatively monotonous, which cannot meet the needs when displaying some special images.

[0004] In order to overcome the deficiencies of flat LED display screens, more and more spherical LED display devices have appeared. Most of the existing spherical LED display screens are polyhedrons composed of multiple flat LED display modules, and a steel structure skeleton is set up inside. , commonly known as "ball cage", "ball cage" external fixed plane LED display module to form a ball screen, there are many ways to form a ball screen, such as triangle method, geodesic method, hexagonal method, pentagonal method, rich Leene structure method, but when the above method is used for large spherical LED display screens to display full-color images, due to inconsistent viewing directions and angles, and full-color LED lights have three wicks of red, green, and blue, different viewing directions and angles will cause problems. There are different visual effects, so the color difference of this spherical LED display is large and the display effect is not good

In addition, since this kind of spherical LED display still uses a flat LED display module, it cannot achieve a round shape in appearance, nor can it truly achieve the purpose of viewing the pattern from multiple angles and having continuity in the text and pattern.

Thirdly, the existing spherical LED display is usually fixed by columns or suspensions, which is not suitable for large-scale spherical screens, cannot be quickly disassembled, and is poor in wind resistance and stability when used outdoors
