Transparent electronic board with retroreflective means

The present invention relates to a transparent display board having a retroreflective preventing means, and more particularly, to prevent the light emitted from the light emitting device in the transparent display board from being output to the rear of the transparent display board by the retroreflective building for residential, office and lodging. The present invention relates to a transparent electronic display board having a retroreflective means that can be installed in a window.

In general, as a light emitting device used outdoors, neon, a cold cathode lamp (CCL: Cold Cathode Lamp), an LED using a light emitting diode (LED) is widely used. In addition, as a light emitting device used indoors, an external electrode fluorescent lamp (EEFL), a cold cathode fluorescent lamp (CCFL), a light emitting diode display board, and the like are used.

Here, neon or cold cathode discharge tube has a drawback of using a high voltage power consumption, high power consumption, risk of electric shock and fire, and short life. In addition, EEFL or CCFL has a disadvantage in that it is difficult to use outdoors in that it uses a high frequency, has a low illuminance and short lifespan.

In addition, in the case of the LED board using the LED, the back surface of the surface emitting light by the processing of the electric wire, the black film treatment, etc. of the rear surface is blocked by the cover, and has the characteristic of emitting light in only one direction.

On the other hand, in recent years, the light emitting device is used as an advertisement signboard rather than simply used as a function of lighting, and has been widely used in interiors and the like as a design with an added aesthetic sense.

However, the light emitting devices as described above are limited in providing aesthetic sense due to the limitation of the size of a lamp, the size of a stand for supporting the light emitting device, and the like.

Therefore, in the related art, a plurality of light emitting elements are attached to the transparent electrode to impart the above aesthetic sensation, and the light is controlled by the controller to emit light to display characters or figures on the transparent electrode, and furthermore, to display a moving image. This was released.

In the transparent display board, a plurality of light emitting devices having two electrodes, three electrodes, or four electrodes are mounted on the transparent electrode. Such a transparent display board is disclosed in Korean Patent No. 79950 (registered on November 21, 2007).

However, such a conventional transparent display board is mainly produced for interior or advertising to give an aesthetic sense, but due to the retroreflective light emitted back to the light source is output to the rear of the transparent display board for people staying in the room, office use And there was a problem that can not be used as a window of a residential building.

In addition, the conventional transparent electronic display board does not have a thermal insulation and insulation function that can maintain the indoor temperature, so when installed near a window of a residential or office building, the cost of heating and heating to properly maintain the indoor temperature by the external temperature increases. There was a problem.

Therefore, the present invention has been made to solve the above-mentioned conventional problems, an object of the present invention to provide a transparent display board having a retroreflective means for preventing light from being output to the rear surface due to retroreflection in the transparent display board.

It is a step of adhering. The protective layer 130 is cured by a UV curing device (not shown) by injecting a resin between the transparent transparent plate 110 and the transparent cover plate 140 temporarily bonded by a double-sided tape. Therefore, the light emitting transparent plate 110 and the cover transparent plate 140 is fixed by a protective layer 130 formed by the resin is injected and cured. In addition, the resin is a transparent resin. In addition, the protective layer 130 protects the light emitting element 111 of the light emitting transparent plate 110, and the cover transparent plate 140 and the light emitting transparent plate 110 are bonded.

The epoxy finishing step (S400) is a step in which a liquid epoxy is injected into the cross-sections of the light emitting transparent plate 110 and the cover transparent plate 140 to finish the transparent light emitting plate 100. The epoxy is applied to a portion and a cross section of the edge of the light emitting transparent plate 110 and the cover transparent plate 140 to prevent the inflow of moisture, air and other foreign matter into the light emitting transparent plate 110 and the cover transparent plate 140. Block it. The finish with the epoxy is preferably limited to the area covered by the transparent display board by a frame capable of acting as a window frame or window frame.

The retroreflective preventing means installation step (S500) is a step of installing a retroreflective preventing means 120 so as to block the output of light by adhering with a non-transparent plastic film or silk screen from the back of the light emitting transparent plate 110. .
