Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a chip type LED display panel having a power supply panel and a controller panel,

[0001] The present invention relates to an LED electric signboard system for outputting information to be transmitted such as characters, images and the like through a light emitting unit having a plurality of LEDs mounted thereon, and more particularly to an LED electric signboard system in which a power source unit and a controller unit are separated from each other, Lt; RTI ID = 0.0 > LED < / RTI >

The display device, which is generally referred to as an 'LED electric signboard system', is installed inside or outside the building to provide predetermined information as shown in FIG. 1 (a) As shown in Fig. 1 (a), it is mainly used as an advertising signboard for outdoor use.

The LED display panel systems 1-1 to 3 mainly used as advertising signs for outdoor use can be installed (1-1) on exposed wall surfaces as shown in FIG. 1 (a), or horizontally (1-2) (1-3).

1B, the LED display panel system 1 includes a plurality of LED pixel panels 10 in which a plurality of LEDs are mounted, on / off LEDs of the LED pixel panel, a controller 30 for controlling the entire LED display panel, a power supply 40 for supplying power, and a light-receiving panel case 50 for mounting the LEDs.

More specifically, a plurality of LED pixel panels 10 and a driving module 20 in the form of a board for driving each LED pixel panel 10 are mounted on the back surface of each LED pixel panel 10, that is, And is fixedly installed at a predetermined height on a surface (rear surface) of the driving module 20. The driving modules 20 thus installed are connected by a data cable.

The controller unit 30 and the power supply unit 40 are also fixedly installed at a predetermined height on the back surface of the LED pixel panel 10.

Therefore, the electric-screen board case 50 requires a considerable thickness d to form an internal space for installing the LED pixel panel 10, the driving module 20, the controller unit 30, and the power supply unit 40 therein do.

In particular, in the case of a two-sided LED electronic signboard system 1-1 in which an LED pixel panel 10 is formed on both the front and back sides as shown in the example of the conventional LED electronic signboard system of FIG. 2, There is a problem that the thickness must be considerably thick.

The conventional single-sided LED electronic signboard system 1 has a problem in that the thickness of the electronic signboard case 50 is considerably large. In the double-sided LED electronic signboard system 1-1, the thickness of the display case 50 is too thick, There was a problem.

Here, when a transparent plate for protecting the light emitting surface is added, the thickness of the display panel case 50 of the LED electric signboard system becomes thicker.

Such a problem has a problem in that it can not satisfy a demand of a buyer who requires a thin LED electronic signboard system, which makes it difficult to use the LED signboard system in various places and spaces.

Conventionally, in place of the pie-type LED device used in the LED electronic signboard system, application No. 10-2012-0005262, which uses a chip type LED device called 'chip LED', which is relatively small in volume, LED chip module for outdoor use '.

The above-mentioned prior art has somewhat reduced the thickness of the entire LED electric signboard system by slightly reducing the thickness of the LED pixel panel (electric light module) by replacing the commonly used pie-shaped LED element with a chip-type LED element, Since the power driver unit and the controller unit as well as the driving driver module are located on the back surface of the light modulator module, the LED module is required to have a considerable thickness as in the conventional LED electric signboard system. In particular, There is a problem that the actual thickness can not be reduced.

[0003] In another conventional technology, the 'slim electronic display' of Application No. 10-2011-0076979 includes a frame, a mounting plate provided on the frame, on which a plurality of LED modules are mounted, A distributor plate having a plurality of connectors for applying an image signal to each of the LED modules, a power supply unit provided in the frame and connected to an external power source, the power supply unit electrically connected to supply power to the distributor plate, And a heat dissipating unit that dissipates heat to the LED module and the power supply unit through the air.

The above-mentioned prior art can improve the structure of the frame, the mounting plate, the distributor plate, the power supply unit, and the heat dissipation unit to reduce the thickness. However, all of the above structures have a laminated structure.

Although the power supply unit is formed integrally with the frame in order to realize a slim type electric signboard, the conventional technique can reduce the total volume, thereby facilitating installation without restriction of the installation space, As described above, when the double-sided LED electronic signboard system is implemented, there is a limit to reduce the thickness by forming at least four layers, and a double-sided LED electronic signboard system is implemented There is a structurally unsuitable problem.

An object of the present invention is to provide a relatively light and thin LED electronic signboard system by minimizing the thickness (width) of the electronic signboard case when implementing the LED signboard system.

The present invention has the effect of providing a relatively light and thin LED electronic signboard system by minimizing the thickness (width) of the electronic signboard case when implementing the LED signboard system.

In addition, since the drive module for driving the LED pixel panel is integrally formed on the LED pixel panel, the overall volume of the LED display panel system is reduced, and the assembly efficiency of components is improved through connector fastening. In particular, Thereby realizing a double-sided LED electric signboard system.
