Abstract

The invention provides an LED display device and an LED display component with the same. The LED display device comprises a substrate (20) and a rear cover (10) connected with the substrate (20), wherein the rear cover (10) comprises a body portion (14) and a hook portion (11) and is provided with a first connection hole (12), the substrate (20) is provided with a second connection hole (22) corresponding to the first connection hole (12) and a hook connection hole (21) corresponding to the hook portion (11). The hook portion (11) is provided with a plug-pull position and a hook position relative to the hook connection hole (21), and when the hook portion (11) is hooked at the hook position, a first fastener is penetratingly arranged in the first connection hole (12) and the connection hole (22), so that the rear cover (10) and the substrate (20) are fixedly connected. The LED display device is simple in assembly and disassembly, and assembly and disassembly time is effectively saved.

Description

technical field [0001] The present invention relates to the technical field of LED display, in particular to an LED display device and an LED display assembly having the same. Background technique [0002] The LED display device in the prior art includes a substrate, one side of the substrate is installed with an LED display lamp, and the other side is installed with a driving circuit board and a power supply. In order to protect the driving circuit board and the power supply, a back cover is connected to the substrate, and the back cover The cover is arranged on the outside of the driving circuit board and the power supply to protect the driving circuit board and the power supply. [0003] The above-mentioned back cover and the base plate are connected by screwing, that is, a plurality of screw holes are provided at the corresponding positions of the back cover and the base plate. In order to ensure a firm connection between the two, it is generally necessary to open a circ...
