Description

Height adjustable type LED display apparatus

The present invention is formed by arranging and installing a plurality of LED panels adjacent to each other on a module frame, and arranged in rows and columns on structural frames installed in various conference rooms, seminar rooms, indoor and outdoor billboards, electronic boards or various performance halls, event sites, and stages. It relates to an LED display device that forms a large screen, and more specifically, a plurality of LED panels on one case are detachably installed by magnets, but each LED panel for the case to form the same plane as the adjacent LED panels. It relates to a height-adjustable LED display device that allows the installation height of the device to be quickly and easily adjusted.

In general, indoor and outdoor various conference rooms, seminar rooms, billboards, electronic boards or various performance halls, event sites, and stages, for example, unit display panels such as CRT, LCD panels, and LED panels are used. Multi-vision systems are widely used, which are arranged in rows and columns to form a large screen.

Each unit display panel constituting such a multi-vision system may display different screens, but mainly displays one screen divided.

Previously, multi-vision systems using CRT and LCD panels were mainstream, but in recent years, they are brighter and have superior contrast compared to multi-vision systems using conventional CRT and LCD panels. Multi-vision systems using high-resolution LED panels are widely used.

In order to compose a multi-vision system using an LED panel, a structure frame for configuring a large screen is installed, and then an LED display device in which a plurality of LED panels are arranged and mounted on one case is arranged and fixed at a predetermined position on the structure frame.

As an example of such an LED display device for a multi-vision system, Korean Utility Model Registration No. 20-0464801 (announced on Feb. 19, 2013) includes an LED panel in which a plurality of LEDs are installed in row and column directions, and the LED panel. Disclosed is an LED display unit including a box-shaped case that is coupled to the front and forms a space surrounded by sidewalls and rear surfaces, and a clamping unit installed in the case and coupling adjacent LED display units to each other. .

Here, the LED panel is sometimes mounted on the box-shaped case through a separate fastening member, but recently, the LED panel is also mounted on the case through a magnet installed on the front edge of the box-shaped case for assembly convenience.

As an example of such an LED display device, in Korean Patent Laid-Open No. 10-2016-0062777 (published on June 3, 2016), a light emitting surface that emits light by inserting a plurality of LEDs and a driving circuit for driving the LED are formed. An LED panel having a circuit surface, and a support frame formed of two long-side frames and two short-side frames disposed along the outer periphery of the LED panel on the opposite side of the light-emitting surface, and connecting the long-side frames between the short-side frames. A panel frame, a plurality of main fixing pins coupled to each of the corners of the panel frame and composed of magnets having a magnetic force at one end, and are coupled to the panel frame in the vicinity of the support frame to control the position of the panel frame. Disclosed is a magnet-attached LED module including a sub-fixing pin for supporting to be fixed.

As described above, in the case of an LED display device in which a plurality of LED panels are arranged and mounted on one case, each LED panel must be arranged on the same plane without forming a step due to a difference in height between the adjacent LED panels. .

However, in the conventional LED display device, a method for adjusting the installation height of each LED panel on the frame so as to form the same plane as the adjacent LED panel has not been properly devised, so the picture quality of the large screen is degraded due to the step formed between the LED panels. There was a problem.

In particular, in high-resolution LED panels with a small dot pitch, which has recently been increasing in demand, the above-described problems are becoming more prominent. In order to match the flatness between the LED panels, the flatness is coincident while visually checking them one by one in a state where they are first attached. If not, there is a problem that the installation time increases because the flatness of the LED panel must be adjusted while repeating the detachment and attachment of the LED panel, and furthermore, the LED panel may be damaged during the detachment process.

In the present invention, the LED panel is formed in a square shape, and the magnet is provided at positions corresponding to the four corners of the LED panel.

In the present invention, the height adjustment member has a screw rod having a female screw hole protruding on the front side so as to be rotatably screwed to the edge of the case, and a male screw rod integrally screwed to the female screw hole of the height adjustment member on the rear side of the magnet It is assumed that the protrusion is formed.

In the present invention, a rotation jig coupling groove is formed around the edge of the height adjustment member, and a rotation jig is partially inserted into the rotation jig coupling groove for rotating the height adjustment member by being engaged with the rotation jig coupling groove on the side of the case. It is assumed that a groove is formed.

In the present invention, a rotation drive groove is formed on the rear surface of the height adjustment member, and an open hole is formed around the rear surface of the case so that an end of the rotation tool is inserted into the rotation drive groove.

In the height-adjustable LED display device as described above, a plurality of LED panels are detachably installed on one case by a magnet, but are integrally coupled thereto through a rotation operation of a height adjustment member rotatably installed at the edge of the case. As the position of the magnet is adjusted, the installation height of each LED panel with respect to the case can be quickly and easily adjusted to form the same plane with the adjacent LED panel, and this greatly improves the picture quality of the large screen without causing a step difference between the LED panels. There is an advantage that can be improved. In addition, it has the effect of shortening the installation time by minimizing the repetitive detachment process by allowing the step difference between adjacent LED panels to be adjusted while the LED panel is attached, and also prevents damage to the LED panel that may occur during the detachment process. There is also an advantage to be able to do.
