Rain-proof curved-surface display screen and rain-proof spherical display screen

Abstract

The invention provides a rain-proof curved-surface display screen and a rain-proof spherical display screen. The rain-proof curved-surface display screen is composed of a framework, panels, a dot matrix display assembly and screws. The framework is constructed in a curved surface shape, the portions, making contact with the edges of the panels, of the framework are coated with water-proof glue or provided with water-proof gaskets, the dot matrix display assembly is installed on the panels in a water-proof mode, and the panels are spliced and tightly attached and fixed to the framework through the screws. The rain-proof spherical display screen is formed by splicing rain-proof curved-surface display screens in a surrounded mode. Compared with the prior art, outdoor curved-surface and spherical display screens can be manufactured and obtained more easily, the structure is simple, splicing is compact, the similarity between the display screens and the curved surface or sphere is high, and the cost is lower; the way in which the dot matrix display assembly is directly installed on the panels in the water-proof mode is simple, and the rain-proof curved-surface display screen and the rain-proof spherical display screen are suitable for batch manufacturing, maintenance and replacement.

Description

technical field [0001] The invention relates to a structure of a dot matrix display screen, in particular to a structure of a rainproof curved display screen and a rainproof spherical display screen. Background technique [0002] Dot matrix display screens such as LED display screens have been widely used. At present, there is also demand for curved and spherical dot-matrix displays in the market. Chinese patent documents CN201812452U "A Spherical LED Display Device" and CN103258482A "A Near-Spherical Dot-Matrix Display and a Near-Spherical Dot-Matrix Display" respectively disclose how to construct a spherical and spherical display skeleton and how to divide the plane The LED display module or flat display panel is used to construct spherical dot matrix display and spherical dot matrix display, but there is no mention of how to prevent rain and water for outdoor application of spherical dot matrix display and spherical dot matrix display. A large number of flat dot-matrix ...

A large number of flat dot-matrix displays for rainproof and waterproof outdoor applications have appeared. figure 1 It is a typical structure of outdoor flat dot matrix display, please refer to figure 1 , the parts of the LED display module are from right to left: mask, PCB board with LED lights, bottom case and waterproof gasket, waterproof glue is filled between the LED lights of the PCB board, and the structure and process adopted are suitable for size rules If the outdoor display screens that are rectangular, flat, and batch-manufactured are extended to outdoor display screens with large size changes, special-shaped, curved or spherical, and personalized outdoor displays, it is obvious that the screen is not easy to divide and design according to curved or spherical surfaces. Manufacturing difficult and costly
