Problems solved by technology

[0004]1) The communication connection between the control system and the display module uses cables, resulting in messy wiring
[0005]2) Due to the various types of cables, there are many types of connectors used, which are not simple, high cost and cumbersome to install
[0006]3) Due to the increase of electromagnetic radiation caused by scattered connecting cables, the high-frequency interference signals generated greatly affect the display effect of the display module
[0007]4) Scattered wiring and multiple types of connectors tend to increase material and labor costs and reduce installation efficiency

Embodiment Construction

[0027] The LED display unit screen 100 of the present invention changes the traditional power supply and signal connection mode, and adopts the direct plug-in connection mode between the LED display module 7 and the electrical box 106, which not only saves costs, but also reduces workload. The power line and signal line are reduced, the electromagnetic radiation interference generated in the working state is reduced, and the environment is greened.

[0028] Such as figure 1 As shown, the LED display unit screen 100 of the present invention consists of a rectangular base frame 101, an electrical box 106 with a base 3 and a DC power supply inside, several vertical beams 2, and a quick plug-in method installed on the base frame 101. Several LED display modules 7 on the front constitute.

[0029] On the base frame 101, there is at least one electrical box 106 and a vertical beam 2 less than the number of the electrical box 106, and the base 3 and the vertical beam 2 are connected...

Abstract

Disclosed is an LED display unit screen. The LED display unit screen is of a modular structure, easy to install, low in cost and strong in interference resistance. The LED display unit screen comprises a plurality of LED display modules and DC power supply, and the LED display modules are clamped on a base frame by a rotary knob lock head; an electric appliance box provided with a base and internally installed with the DC power supply is disposed on the base frame and the LED display module is clamped between the base and a left beam or a right beam; an interface board is arranged in the electric appliance box, and the interface board is provided with a multilayer PCB board with functions of high frequency signal shielding and electromagnetic radiation reduction. A signal receiving module and the DC power supply are communicated with the interface board and the LED display module in a busbar and a gill bar mode. All electric signals and power supply current are transmitted through an internal layer of the interface board, and therefore the usage amount of the open wire cable is significantly reduced. The upper external layer and the lower external layer of the interface board are grounding copper foil, so that high frequency signals can be shielded by the interface board in the internal layer of the interface board and the electromagnetic pollution for the environment by the high frequency signals and the signal disturbance by the high frequency signals for the LED display module are avoided.

Description

technical field [0001] The invention relates to an LED display screen, in particular to an LED display unit screen without open wire connection between a control module and an LED display module. Background technique [0002] The LED display screen in the prior art is composed of a display module and a box or frame for receiving the display module. The display module includes a PCB circuit board with several LED lamp beads and a module bottom case. The PCB circuit board is installed on The LED display module is formed in the bottom shell of the module, and the LED display module is installed on the box or frame; the control system of the display screen includes a display signal sending card, a receiving card, and a HUB board for multiple output signals (also known as Interface board), HUB board, LED display module and power supply interface are mostly connected by cables and power lines, and the DC power supply for PCB circuit board, signal receiving control module and sever...
