Description

Display device {DISPLAY DEVICE}

The present invention relates to a display apparatus, and more particularly, to a display apparatus for displaying video information.

The outdoor large display device is used to promote a business for public, guided or commercial purposes, and is used in various forms to deliver image information. Such a display device may be installed in a place where people pass frequently or at an event place by expressing specific image information.

In general, an outdoor display device may be classified into a fixed type that is fixedly installed on a structure such as a building, and a movable type that is made of a relatively small and light weight material without being fixedly installed on the structure such as a fixed type.

In the past, outdoor display devices had a film on which advertising contents were displayed on the front, and a light emitter was installed inside, so that light was transmitted through the film during the day and at night to recognize the phrase. This is provided with light emitting means in order to attract more attention at daytime as well as daytime. Such light emitting means have been used mainly for fluorescent lamps in the past, but the lifespan is short, and the maintenance cost is required to replace the whole of one life rather than partial replacement in order to obtain overall uniform brightness according to the hassle and lifespan. This high had its drawbacks. In addition, only a still image can be expressed, and thus a moving image cannot be displayed.

As another display means, the neon sign had the advantage of forming various shapes and characters by bending the neon tube, but the manufacturing and replacement cost was expensive, and the power consumption was high, and the maintenance cost increased.

Accordingly, a light emitting diode (LED), that is, a display means for displaying a still image as well as a moving image using an LED element has been in the spotlight, which is suitable for a large screen, and the demand is increasing very much.

LED refers to a semiconductor that emits light when a direct current flows. The LED is a display device that converts an electrical signal into a light signal. Generally, light is generated when a current flows through a PN junction of a compound semiconductor such as GaP or GaAs. As a light emitting device using the light emitting device, light of a predetermined wavelength can be generated by adjusting the component ratio of a semiconductor compound in manufacturing a light emitting diode.

LED is used not only for medical use that uses a certain wavelength, but also for plant growth promotion. Especially, LED has low power consumption and high visibility. Recently, LED has been widely used in traffic lights, vehicle rear lamps, and outdoor advertising signs. It is being applied, the scope of application is gradually expanded to replace the known lighting device and display device. Such LED boards are widely used as various lighting or display means such as LEDs are arranged at regular intervals, and the screens can be displayed by varying light emission patterns according to control signals from the control unit.

Currently, a large display device installed in a rooftop or an outer wall of a structure such as a building, among outdoor display devices, is manufactured to have a very large display area having a large display area to facilitate information transmission even at a long distance.
