Description

Easy repair type display device {DISPLAY DEVICE WITH EASY REPAIR}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple maintenance type display device, and more particularly, to a simple maintenance type display device for use in image display, lighting, and the like.

The outdoor large display device may be used for guidance or commercial purposes, and various forms and methods are used to convey various contents. Such a large display device displays various image information and is installed in a place where a lot of people pass.

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

In the past, the outdoor display device installed a film on which advertising text was displayed on the front and a light emitter was installed inside so that the text could be recognized by light passing through the film during the day and at night. It is equipped with light emitting means to attract more attention during the day as well as at night. Such light emitting means have been used mainly for fluorescent lamps in the past, but have a short lifespan and are often cumbersome because they need to be replaced frequently. Therefore, in order to obtain a uniform brightness as a whole, they have to be replaced rather than partial replacements.

In addition, there is a neon sign device as another display device, which has the advantage of forming a variety of figures and characters by bending the neon tube, but the manufacturing and replacement cost is expensive, and the power consumption has a disadvantage.

Accordingly, a light emitting diode (LED), that is, a display device that displays a still image as well as a moving image using an LED element is in the spotlight, and is particularly suitable for a large screen, and thus there is a great demand.

LED is a semiconductor that emits light when DC flows. It is a display device that converts an electric signal into an optical signal. Generally, a light emitter using a phenomenon that light is generated when a current flows through a PN junction of a compound semiconductor such as GaP or GaAs. As the device, it is possible to generate light of a constant wavelength by adjusting the component ratio of the semiconductor compound in manufacturing the light emitting diode.

LED is used not only for medical use using a certain wavelength, but also for promoting plant growth.In particular, LED is widely used for traffic lights, vehicle rear lamps, and outdoor advertising signs due to its high visibility despite the low power consumption. Is being applied. In addition, the application range has been expanded to gradually replace the conventional lighting device and display device. Display devices using such LEDs are widely used as various lighting or display means, such as arranging LEDs at regular intervals and displaying a screen according to a control signal provided from a controller.

Currently, large display devices installed on a roof or an outer wall of a structure such as a building are manufactured to have a very large display area having a large display area so that information can be easily transmitted to a long distance. In other words, by installing a display in a part of a building as well as a large part of a building, the display size can be maximized. Accordingly, information can be transmitted more effectively and an advertisement effect can be enhanced.

In addition, among large display devices, there are cluster type display devices in which a plurality of cluster modules are installed on a wall surface of a building or the like to display an image signal.

1 is a diagram illustrating a conventional clustered display device, and FIG. 2 is an exploded perspective view of a cluster module of a conventional clustered display device.

The cluster module includes a base 10, an LED element 21, a substrate 20, and a cover 30. An LED element 21 is mounted on the substrate 20, and the substrate 20 is a base 10. Is inserted into The cover 30 is coupled to the base 10 to protect the substrate 20. A through hole is formed at a position corresponding to the LED of the cover 30 so that the LED light can be displayed through the cover 30. In this case, a lens may be coupled to the LED element 21. The neighboring cluster modules may be connected to each other by a driving line 50 including a power line and a signal line, and current and driving signals may be applied to each cluster module to display an image signal.

The cluster module is fastened by screws 40, which pass through the cover 30, the substrate 20 and the base 10 from the front surface of the cover 30, and are joined to the wall to tighten the cluster. The module is fixed to the wall.

If a failure occurs while using a device installed on the wall of a high-rise building, the failed cluster module should be replaced. After cutting the drive line 50 connected to the upper and lower parts of the cluster module, loosen the screw 40 to remove the cluster module. After separating from the wall and attaching a new cluster module to the wall, the connection portion can be connected to the upper and lower drive lines 50 to waterproof the connection.

At this time, it is preferable to secure a space in which the worker can work in front of the wall surface, but the working space cannot be secured when the installation position is high. Therefore, the operator should work on boarding equipment such as a crane or hanging on a rope, etc. In particular, it is very inconvenient to cut the driving line 50 using a tool rather than the ground, tighten and loosen the screw 40, and the like. The disadvantage is that the tool can be dropped during operation. In fact, there are many safety accidents caused by the work tool slipping from the operator's hand and falling to the ground.

In addition, the maintenance process such as cutting and connecting the drive line 50 is difficult to take a lot of work time.

In addition, since the device is used in an extreme environment exposed to high-rise outdoors, failure may occur repeatedly due to flooding of repaired parts, in particular the connection of the drive line 50, which is connected again after cutting, in this case short circuit Due to this, there is a problem that a plurality of peripheral cluster modules may be damaged.

In addition, there is a problem that the screw thread collapse due to abrasion during several repairs, or the work is not easy due to corrosion of the screw 40 due to rainwater and contamination in an environment exposed to the outdoors.

In addition, since the screw 40 is exposed to the front, there is a disadvantage that the light emitting side is not neat.
