Disclosed is a waterproof substrate, including: two mounting surfaces disposed facing away from each other; and at least one waterproof protrusion provided on at least one of the two mounting surfaces and including: a protrusion body connected with the mounting surface, and one end of the protrusion body away from the waterproof substrate includes a connecting end surface; and at least two waterproof ribs, and each of the waterproof ribs is provided on the connecting end surface respectively and is gradually inclined outwardly in a direction away from the connecting end surface respectively.

Waterproof assembly and display screen

The present disclosure provides a front maintenance display screen module, including: a bottom case, a PCB provided on the bottom case, and a through-hole structure penetrating the bottom case and the PCB. The through-hole structure includes a step structure at one end of the through hole structure near the PCB, and the step structure includes a convex portion and a step portion. The convex portion is configured to penetrate the PCB, a gap is provided between the convex portion and the PCB. The step portion includes a groove surrounding the convex portion. A side of the PCB near the bottom case is abutted against an edge of the groove. A sealant layer is provided in the gap and the groove.

Display screen module and display screen

An LED display is provided in the present disclosure. The LED display includes a casing frame and an LED module. The LED module is fixedly connected with the casing frame by a locking knob, chucks and magnets fitted with each other, and positioning holes and positioning posts fitted with each other. The LED display further includes protective covers, a support base, a power rear cover, and a system control box. The protective covers are connected with the casing frame by fitting the positioning posts with the positioning holes. The support base and the casing frame are connected by fitting the positioning posts with the positioning holes and by a quick fixation with screws. The power rear cover is mounted on the system control box by a latch-hinge to facilitate the assembly and disassembly of various portions of the LED display.

LED display with quick maintenance structure

The present invention relates to a display device comprising a mounting board and a display panel mounted on the mounting board and comprising a plurality of display modules arranged in an array, and further comprising a control module and a plurality of driving modules corresponding to the display modules. The control module is capable of controlling the driving modules to drive the corresponding display modules to extend. When the display device is powered on, the control module is electrically coupled to the driving module such that the driving module receives a signal from the control module and controls the display module to extend in response to the signal; when the driving module is started, the corresponding display module moves along with the driving module and automatically extends, facilitating the maintenance of the display device.
