Description

Technical Field

[0001] This utility model relates to the field of LED display technology, and in particular to a cabinet and an LED display. Background Technology

[0002] LED displays are flat display screens composed of light-emitting diode dot matrix modules or pixel units. Due to their advantages such as high luminous efficiency, long service life, and strong adaptability to indoor and outdoor environments, they are widely used in various fields.

[0003] Existing LED displays typically consist of a cabinet and multiple module light panels mounted on the cabinet. To avoid the tedious work of removing and installing screws, magnetic adsorption is generally used to securely fix the module light panels to the cabinet. Specifically, for example... Figures 1 to 3 As shown, the housing 10 has multiple spaced positioning slots 101. Each positioning slot 101 has at least one mounting post 20 on its circumferential sidewall and at its center. Each mounting post 20 has a circular magnet 30. The sum of the total height of the mounting post 20 and the thickness of the circular magnet 30 is less than the depth of the positioning slot 101. In other words, the upper surface of the circular magnet 30 is lower than the upper surface of the frame of the housing 10. In this way, when the module light panel is positioned on the positioning slot 101, the module light panel can be fixed on the housing 10 by the adsorption of the circular magnet 30.

[0004] However, in actual use, because the upper surface of the circular magnet is lower than the upper surface of the cabinet frame, when the module light panel is placed on the cabinet, the surface of the module light panel directly abuts against the upper surface of the cabinet frame. The area on the module light panel directly above the circular magnet will be drawn inwards into the cabinet due to the magnet's attraction, resulting in a corrugated appearance where each module light panel assembled on the cabinet is lower in the middle and higher around the edges. This severely affects the performance of the LED display screen. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a cabinet and an LED display screen, which aims to solve the technical problem that in the existing method of fixing the module light panels on the cabinet by setting mounting columns and circular magnets, the upper surface of the circular magnet is lower than the upper surface of the cabinet frame, resulting in a corrugated phenomenon where each module light panel assembled on the cabinet is lower in the middle and higher around the edges, which seriously affects the performance of the LED display screen.
