[0001] Flexible LED billboards module [0002]

In particular, the present invention relates to a light emitting module for a transparent LED display panel using a chip LED module having a chip LED device mounted thereon, and more particularly, to a light emitting module for an LED display panel which constitutes a light emitting portion of an LED electric signboard for outputting graphic information such as characters, images and the like.

An LED display board for advertisement is a kind of image display apparatus which arranges light emitting diodes in a matrix form to output characters, figures and the like, and is installed on an outer wall or the inside of a building or the like to provide advertising means for providing various information such as letters, figures, As shown in the figure, which is an example of the outdoor installation of a 1-LED electronic signboard, it is installed as an auxiliary signboard on the outer wall of a building.

As shown in FIG. 1, the LED display panel 1 includes a light emitting portion 10 formed by coupling an LED light emitting module 11 composed of a plurality of LEDs (Light Emitting Diode) A driving driver module 20 for driving each ELD light emitting module 11 of the module 10 and a power module control module 30 for controlling and driving the entirety of the LED electric signboard 1 and a power module 40 And an electric sign board case 50 for installing these.

The conventional LED electronic signboard 1 comprises a light emitting unit 10 coupled to an LED light emitting module 11 having a plurality of LEDs mounted in a matrix form on a printed circuit board (PCB) Due to the structure provided in the electric sign board case 50, there is a considerable thickness and volume, and thus space restriction is considerable in installing the LED signboard 1.

Particularly, when installed on a glass (window) of a building or the like, there is a problem of deteriorating mining and aesthetics by covering the glass (window) of the building.

Therefore, the conventional LED electric signboard 1 can not be installed in the same place as a window, as shown in FIG. 1, but is installed on an outer wall of a building.

In order to solve such a problem, the prior art application No. 10-2004-0063166 "coupling structure of the LED module" has been disclosed.

In the conventional technique, a module plate in which a plurality of through holes are regularly arranged, an IC for surface-mounting a plurality of LEDs on one surface of the module plate and a plurality of surface mounted LEDs on the other surface, It is possible to easily combine the LED module with a plurality of LED modules to form an illumination or an image display device, The LED module can be mounted on a glass surface of a building or the like by using the LED module as an illumination or an image display device so that the situation of the opposite surface can be seen through the through hole in the front or rear surface of the LED module, When LED modules are applied to lighting or image display devices, it is necessary to use conventional The present invention provides a coupling structure of an LED module that improves the hermeticity of a display board and improves the space limitation due to the installation of the LED module.

However, although the above-mentioned conventional art has the effect of making the LED display mounted on the module plate in which a plurality of through holes of the LED electric sign board 1 are regularly arranged, permitting the sighting of the LED display panel 1 compared to the conventional LED electric sign board 1, So that the effect of not substantially degrading the mining or the view can not be exhibited. The reason for this is that the module plate, which must have a predetermined supporting force, is limited in its size to form the perforation hole, and the module plate itself formed in the lattice shape may damage the aesthetic appearance.

That is, the conventional technique described above is merely a method of forming a plurality of through holes on a circuit board on which an LED is mounted, and there is a problem that the module plate itself is easily broken or broken by bending due to the formation of a plurality of through holes.

Another prior art application No. 10-2006-0035414 "a transparent electronic board and a line forming chip used therein" includes a first transparent plate; A second transparent plate disposed at a predetermined distance from the first transparent plate; A plurality of first electrode regions and a plurality of second electrode regions arranged in a matrix form, at least one of the plurality of first electrode regions being adjacent to the four second electrode regions; A pair of first electrodes electrically connected to a pair of adjacent first electrode regions and a pair of second electrode regions adjacent to the pair of first electrode regions to which the first electrode is connected, A plurality of first electrode lines formed in a first direction and a plurality of second electrode lines formed in a first direction, A plurality of line forming chips attached to the transparent electrodes so as to form a plurality of second signal lines formed in a second direction intersecting the first signal lines; A plurality of chip LEDs having an anode electrode connected to one of the first electrode regions to be connected to the first signal line, and a cathode electrode connected to one of the second electrode regions to be connected to the second signal line; Wow; And a control unit for selectively applying a control signal to the plurality of first signal lines and the plurality of second signal lines so that the plurality of chip LEDs are selectively turned on and off, Thickness is thin, but the effect of video can be realized.

In the above-described prior art, a circuit is constituted by a transparent electrode between two spaced apart first transparent plates and a second transparent plate, and a plurality of chip LEDs are arranged to constitute a light emitting portion. As compared with the prior art Application No. 10-2004-0063166 Thereby constituting a transparent EL display board.

Further, there is a problem in that it is difficult to provide an LED electric sign board module of various sizes (size) desired by a user in accordance with a place where a transparent LED electric signboard such as a windshield is to be installed.

In particular, in the case of a bad LED, there is a problem that the entire light emitting panel module must be replaced, which makes maintenance of the LED electric signboard difficult and causes a lot of maintenance cost. Also, since the transparent electrode is used, There is a significant limitation, and various types of modification are difficult.

Furthermore, since the electrical reliability of the transparent electrode itself is low, the defective ratio is relatively high as compared with the metal electrode.

In addition, since the LED display panel of the general type shown in FIG. 1 and the conventional arts have a plate-like structure in which basic shapes are stacked, it is impossible to deform the shape such as warpage and the shape of the curved pole, the curved glass window, There are many limitations to installing in uneven places.
