Description

Technical Field

[0001] This utility model relates to the field of LED display technology, and more specifically, to an aging test structure for display module. Background Technology

[0002] LED display modules typically undergo aging tests during manufacturing to ensure product quality. During aging tests, the modules are usually mounted on an aging rack, the dimensions of which are usually matched to the specifications of the LED display modules to ensure the smooth execution of the aging test.

[0003] However, with the increasing diversification of LED products and the continuous launch of new LED display products, these new products differ from conventional modules in various aspects. During aging tests, new products require modules to be assembled into the cabinet before powering on and aging can begin. Completely assembled modules cannot be aged on the existing aging racks of conventional modules. Furthermore, because the dimensions of individual modules in new products differ from those in conventional modules, they cannot be adapted to the spacing of the aging racks. For example, the module size of a new product is 250*250mm (1:1), while the size of a conventional module is 320*160mm (2:1). Conventional outdoor modules consist of a light board, a base shell, and a faceplate. After assembly, a single module can be tested for illumination and aging. During aging, the module is directly attached to the aging rack using magnets on the base shell. A transmitting card connects multiple modules via a ribbon cable for signal transmission. When assembling a screen, several modules are magnetically attached to the cabinet. The transmitting card hangs directly without affecting the transmission effect. The new product has a different structural design. Signals and power are transmitted through a HUB board. One HUB board connects four modules. The HUB board is relatively large. The male connector on the HUB is directly plugged into the female connector on the module. It does not need to be connected by ribbon cable. Hanging it directly outside the aging rack will affect the transmission effect.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content
