Description

Electronic display board with removable LED module {DISPLAY PANEL INCLUDING LED MODULES EASY OF CONJUNCTION AND DISJUNCTION}

The present invention relates to a display board having an LED module that is easily removable, and more particularly, to a display panel having a detachable LED module that can be easily fastened or separated from the frame of the display board.

In modern times, the demand for large screens is increasing in advertising and display of public places. Currently, LED is used as a display means of many large screens, because it is easier to enlarge the size than the conventional means, consumes little electric energy, and has a long life with low maintenance cost.

Currently, large LED signs using LEDs are used in various places such as stadium billboards, outdoor advertisements, indoor advertisements, public signs, and information display panels, and their construction methods are also various.

Representatively, the LED panel is standardized in a block type, and each block is combined to form a large screen by stacking bricks, and there is a method of attaching each LED panel device to a frame structure installed according to the screen size.

FIG. 1 is a perspective view of an electronic board with an LED module shown in Korean Patent No. 751049, and is shown in the prior art in Korean Patent No. 751049.

The electronic display plate shown in FIG. 1 of Korean Patent No. 751049 is configured by detachably installing a plurality of LED modules 110 in which a plurality of LEDs are installed on a front surface of a frame 120 having a predetermined accommodation space. In addition, the predetermined receiving space formed in the frame 120 of the display board is provided with power supply means for supplying power to the electro-optical module 110 and control means for selectively controlling the power supplied thereto. The door is installed to protect the power supply means and the control means is configured to allow the installation and maintenance of the power supply means and control means.

As illustrated in FIGS. 2A and 2B, the electric light plate configured as described above is fastened to the frame by tightening the fixing screw 140 in the screw hole formed in the frame constituting the electric light module 110. The electro-optic module 110 fixed to the frame 120 is a screw thread formed in the frame of the electro-optical module 110 by passing the fixing screw 140 through the through-hole 240 formed through the frame 120 as shown The fixing screw 140 must be tightened from the rear side when being installed by being fixed to the formed screw hole.

In this way, when the display board is installed at the front of the structure such as a wall by fastening the fixing screw 140 to fix the screw 140, the installation should be spaced at least a certain distance from the structure so that the worker can enter and exit between the display board and the wall. do.

However, due to the limitation of the installation place, the display board is often installed in close contact with the front surface of a structure such as a wall. When the structure and the display board are installed in close proximity to each other, there is no space for an operator to enter between the display board and the structure. Some of the electric light module 110 is damaged, and even when repairing, only the failed electric light module 110 cannot be disassembled.
