Description

Billboard device

The present invention relates to a billboard apparatus, and more particularly, to a billboard apparatus capable of displaying a predetermined letter, figure, graphic, or any other pattern that is displayed clearly, as well as having a simple structure and minimizing power consumption. .

As is known, a media such as a television is used to advertise a specific product or content, but recently, a fixed advertisement device is used to intensively advertise or promote a certain heartache or content in a specific region or a specific time period. It also uses advertising vehicles to advertise and promote mobile. As an example of such an advertisement device, a neon sign format or an electronic signboard format may be used to promote a predetermined advertisement content imprinted with a painting or printing technique on a fixed body (plate) or a mobile body having various forms, or to maximize the advertising effect. In particular, recently, advertising apparatuses using lamps, LCDs, VFDs, and PDPs have been used.

Among such conventional advertising devices, the display panel for advertisement as disclosed in Korean Utility Model Publication No. 97-02290 includes a housing for enclosing a circuit and a connection joint which is electrically connected from an external main controller. And a plurality of lamps positioned in front of the housing and blinking in response to a signal from the main controller, and a shading portion in which thin plate blocking pieces protrude from the support frame to the front of the lamp to shade sunlight. Despite the effect of preventing the incidence of sunlight to provide a predetermined advertising effect, the use of a large number of relatively large volume of the lamp, the structure is complicated, especially thick and relatively high power consumption lamps There was a problem that the power consumption is excessively consumed by using.

In addition, the color display device disclosed in Japanese Patent Application Laid-Open No. Hei 6-8621 has a display portion for emitting band-shaped spectral light having a peak in a specific wavelength region, and a filter having a smaller transmittance in the specific wavelength region than other regions. And a guest host liquid crystal cell that transmits light including light in a region having a small transmittance of the filter, and a driving unit for driving the display unit and the liquid crystal cell. Although there is an effect of improving, components such as a display unit such as a fluorescent display tube (VFD), a neutral polarizer, and a guest host liquid crystal cell are relatively expensive, have a relatively high power consumption, and need to control the display unit and the guest host liquid crystal cell separately. Complexity and difficulty of construction are still present problems.

On the other hand, in recent years, interest in EL (Electro Luminescence) devices has been raised to realize low cost large area full color display devices. The EL device has a structure in which a thin film containing a fluorescent organic compound is sandwiched between a cathode and an anode, and electrons and holes are injected into the thin film to recombine to generate excitons, and the excitons are deactivated. It is a device that emits light by emitting light, and it is possible to emit light with high brightness of 100-100,000 ㏅ / ㎡ even at low voltage of 10V or less, and it is possible to emit light from blue to red according to the type of fluorescent material. There is a trend that the research to use for the display device as described above is being actively conducted.

Accordingly, the present invention has been made to solve the above problems and problems, the main purpose of the present invention is to provide a billboard device that is simple in structure and configuration, excellent in clarity and recognition, and can save power consumption. have.

Another object of the present invention is to provide a billboard device using an EL element as a light emitting element to achieve the main purpose.

These objects are supported by a support plate fixed to a support or a mobile body, an insulator installed on the support plate, a transparent sheet disposed on the insulator, and a predetermined shape and color. And a display portion composed of light emitting elements disposed on the transparent sheet, a controller for controlling the lighting time and the order of lighting of each light emitting element disposed on the display portion, and a transparent cover for protecting the display portion from the outside. It can be achieved by a billboard device characterized in that.

According to one feature according to the present invention, between the display portion and the cover shields the pattern portion cut out according to the character, figure or pattern shape formed by the light emitting element of the display portion, and other portions except the character, figure or pattern portion A pattern layer having a base portion to be inserted is inserted.

According to another feature of the present invention, the light emitting device of the display unit is an EL (Electro Luminescence) device.

Hereinafter, a preferred embodiment of the billboard device according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a billboard device according to the present invention, Figure 2 is a perspective view showing a state of use as a billboard device according to the present invention is fully coupled.

According to FIGS. 1 and 2, the billboard apparatus according to the present invention may be supported or installed at a predetermined position of a building or a support or at a predetermined moving vehicle such as an advertisement vehicle, and also may increase the rigidity of the entire billboard apparatus. And a support plate 10. The support plate 10 is preferably formed of a metallic material such as aluminum or a synthetic resin material such as acrylic so as to maintain the rigidity of itself or the entire billboard device as well as to be kept lightweight for ease of installation.

On this support plate 10 there is provided an insulator 20 for blocking heat or electricity which can be generated in the display section described below in detail or which can be generated from a support or a vehicle. Since the insulator 20 is actually insignificant in heat generated by the display unit described later, it is preferable that the insulator 20 is formed of vinyl having excellent insulating properties, but may be formed of a material such as rubber or synthetic resin.

The display unit 30 is provided on the insulator 20, and the display unit 30 is particularly formed in a sheet shape in which a plurality of light emitting elements capable of emitting a predetermined color are distributed in the form of particles or pixels. desirable.

In detail, the display unit 30 using such a light emitting device includes a transparent sheet 32, which may be, for example, a glass substrate or a transparent plastic, as shown in detail in FIG. 3. On the transparent sheet 32, a plurality of light emitting elements 34 are attached or integrally formed in a predetermined distribution state. In particular, the light emitting elements 34 have high luminance and light emission characteristics even with small power consumption as described above. It is preferred to be formed of an EL (Electro Luminescence) element capable of exhibiting. Looking at the configuration of each light emitting device 34 as described above, on the transparent sheet 32, the reflective layer 34a, the first transparent conductive film 34b, the transport layer 34c, the light emitting layer 34d, the metal layer 34e And the second transparent conductive film 34f are sequentially formed. Of course, the reflective layer 34a is formed of a metal thin film such as aluminum, and the metal layer 34e stacked on the light emitting layer 34d is formed as an extremely thin thin film to serve as a cathode and has a predetermined color from the light emitting layer 34d. It transmits the colored light which can be emitted. Here, the second transparent conductive film 34f is applied thereon to prevent the high resistance of the light emitting layer 34d from being able to exert sufficient function as the cathode. The light emitting element 34 configured as described above can be formed in a thin film or sheet form with the total thickness of the display part being extremely thin, and the mode of operation of the light emitting device 34 will be described in detail. The current injected from the electrode is converted into light in the light emitting layer 34d, and the light is emitted through the second transparent conductive film 34f. Of course, the configuration and function of such an EL element is a matter generally known recently, and further detailed description is omitted for clarity.

On the other hand, as described above, each of the light emitting elements 34 emitting a predetermined color may be uniformly distributed throughout the transparent sheet 32, wherein each of the light emitting elements 34 is a user The transparent sheet 32 may be partitioned by the desired display form or by the color to set each light emitting area, and then a light emitting device that emits a color corresponding to each area may be disposed in the corresponding area to form a light emitting device group. Of course, each light emitting device may be disposed in a manner of presetting a predetermined pattern desired by the user on the transparent sheet 32 and patterning predetermined light emitting devices that emit a color corresponding to the pattern, as will be described later in detail. have.

Alternatively, the entirety of the display portion 30 may be entirely coated to protect itself using a transparent material. In addition, as a replacement for the light emitting device as described above, the configuration of the sheet of the display unit may be different. That is, the sheet itself may be formed in a shape including fluid molecules that may collide with each other when an electric current is applied so that the sheet may emit light due to the collision of respective molecular particles when the electric current is applied.

In addition, the controller 40 is connected to the display unit 30 to actually control the light emission of the display unit 30, more specifically, each light emitting element 34 or a group of light emitting elements. The controller 40 is actually electrically connected to each of the light emitting elements 34 or the light emitting element group through a wire. In addition, the controller 40 basically includes a lighting controller 42 and a timing controller 44, where the lighting controller 42 includes the entire display unit 30, that is, each of the light emitting elements 34 as a whole. It is configured to control the supply of electric current so as to turn on or turn off or to turn on or turn off each of the light emitting elements 34 independently or partially. On the other hand, the timing controller 44 is configured to control not only the lighting time of each light emitting element 34 or the light emitting element group, but also the sequential lighting sequence of each light emitting element or the light emitting element group. Each control unit configured as described above can automatically perform the lighting time and the lighting sequence of each corresponding light emitting device in a manner desired by an operator or a user. Of course, the controller 40 is supplied with electric current from a power supply unit (not shown), for example, when a billboard is installed in a large building, a general power source can be used. The power source can be supplied using the vehicle's power source or a separate small battery, which is understood to be possible because the power consumption of the light emitting device is very small.

In addition, a pattern layer 50 is formed on the display unit 30. The pattern layer 50 is a character, figure, or pattern part displayed in each emission area of a display unit forming a character, figure, or pattern desired by a user. And a pattern portion 52 cut out to expose the portion, and a base portion 54 shielding portions other than letters, figures, or patterns formed on the display portion. According to the structure of the pattern layer, the corresponding letters, figures, or patterns become relatively clearer than the surroundings, so that the display can be recognized more clearly.

In addition, a cover 60 is provided outside the pattern layer 50 to protect the pattern layer 50, the display unit 30, and the entire billboard device from the outside. Of course, the cover 60 is preferably formed of a transparent material so as to transmit the light emitted from the display unit 30 without interference, and it is preferable to maintain some rigidity so as to maintain resistance to external impact.

According to the operation mode of the billboard device configured as described above, first, the user controls the lighting controller 42 and the timing controller 44 built in the controller 40 to be linked to each other, respectively, so that each light emitting device of the display unit 30 can be controlled. Alternatively, whether the light emitting element group is turned on, the lighting time and the lighting sequence are set appropriately. As such, as the controllers 42 and 44 are arbitrarily set, the controller 40 supplies current according to the lighting time and the lighting sequence set for each light emitting element 34 or the light emitting element group of the display unit 30. Will be. For example, as shown in FIG. 5, the user may display the first area A, the second area B, the third area C, the fourth area D, and the fifth area E of the display unit 30. If the controller is set to emit light at predetermined time intervals in turn, each area may be turned on in the set order. Of course, such a lighting method is only one process, and the lighting of each area of the display unit can be performed by various processes, and of course, each of these processes can be performed continuously. Accordingly, the user can turn on a predetermined display as a whole or light only a desired display as well as change the lighting order of each display in various ways.

In addition, when letters, figures, or patterns caused by light emission of the light emitting device or the light emitting device group of the display unit 30 are turned on, the respective light emitting regions A are provided by the pattern layer 50 provided on the display unit 30. By exposing only letters, figures, or patterns of B, C, D, and E, while shielding portions other than those parts, each character, figure, or pattern can be made relatively clearer, and thus displayed by light emission. Sharpness and recognition of the letters, figures, or patterns may be improved.

As a result, light emitted from each light emitting element 34 or the light emitting area AE of the display unit 30 executed by a process set by the user using the controller 40 in a predetermined character, figure or pattern form. The light is vividly emitted to the outside through the transparent cover 60 to achieve a predetermined advertising or promotional effect.

Of course, it is understood that characters, figures, or patterns formed by the light emitting elements in the display unit may be taken in various forms according to a user's desired purpose without being limited to those shown in the drawings.

Billboard device of the present invention described in detail above is very thin, light weight and compact the overall thickness can be easily installed regardless of the installation location, and also has the effect of minimizing the installation area.

In addition, by adopting a light emitting device such as an EL device having excellent light emitting ability, the clarity and recognition can be increased, and the power consumption can be optimally saved.
