Description

[0001] MODULE TYPE DISPLAY APPARATUS [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a modular display device, and more particularly, to a modular display device installed in an outdoor place or the like to display a large image.

Billboards are used for promotional purposes for business purposes and for public purposes, and are used in various forms and ways to convey accurate information. These billboards are installed in a variety of places such as public transportation facilities, restaurants, fast food shops, and the like, in which passers-by are described by a specific advertisement image.

Generally, the outdoor billboard is a fixed billboard fixedly installed on a structure such as a building, and a movable billboard that is made of a relatively small and lightweight material, such as the fixed billboard, which is not fixed to the structure.

In the outdoor billboard, the film on which the advertising text was displayed was installed on the front side, and the light was installed inside, so that the light was transmitted through the film during the day and night, so that the text could be recognized. It is equipped with a light emitting means to induce more attention, not only at night, but also during the day. Such a light-emitting means has been used mainly in fluorescent lamps in the past, but since it has a short life span, it is necessary to replace the entire light-emitting element instead of partial replacement in order to obtain uniform brightness, Is high.

As another display means, the neon sign has the advantage of bending the neon tube to form various figures and letters, but it has disadvantages of high manufacturing and replacement cost, high power consumption, and high maintenance cost.

Accordingly, a display means for displaying not only a still image but also a moving image by using a light emitting diode (LED), that is, an LED element, is in the limelight, and the demand for it is increasing due to advantages of realizing a large screen .

The term "LED" refers to a semiconductor that emits light when a direct current flows. It may be an indicator for converting an electrical signal into a light signal. In general, a phenomenon occurs when a current flows through a PN junction of a compound semiconductor such as GaP or GaAs The light emitting device can emit light of a constant wavelength by controlling the composition ratio of the semiconductor compound in the production of the light emitting diode.

LEDs are used not only for medical use using wavelengths of a predetermined area but also for promoting the growth of plants. Especially, due to advantages such as low power consumption and high visibility, lamps, lamps for vehicles and signboards for outdoor advertisements, Have been gradually enlarged to replace the conventional illumination devices and display devices. A display panel or the like using such an LED is widely used as a variety of lighting or display means and the like by disposing the LEDs at regular intervals and displaying a screen with a different light emission pattern according to a control signal from the control unit.

Currently, large billboards in billboards are produced in very large size with a very large display area to facilitate information transmission even in remote areas. That is, by arranging and arranging a large number of LEDs to maximize the display size, it is possible to realize a large screen which has not been able to be realized in the past, and thus information can be transmitted more effectively.
