Description

[0001] PORTABLE DISPLAY APPARATUS [0002]

The present invention relates to a mobile display device, and more particularly, to a mobile display device capable of displaying an image by simple movement and installation.

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.

In the past, the outdoor billboards were installed on the front side of a film that displays the advertisement text, and a light emitting body was installed in the inside, so that the light was transmitted through the film during the day and night. 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, display means for displaying not only a still image but also a moving picture by using a light emitting diode (LED), that is, an LED element, is in the limelight.

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. Particularly, they have advantages of low power consumption and high visibility, and recently, they are widely used for traffic lights, rear lamps for vehicles, And its application range has been gradually enlarged to replace the conventionally known illumination device and display device. 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 manufactured to have a relatively large display area so that information can be easily transmitted even at a long distance.
