Description

LED Display Board {LED DISPLAY BOARD}

The present invention relates to an LED signboard, and more particularly, to an LED signboard that can maximize the information providing effect and advertising effect, and can significantly reduce maintenance and repair costs by reducing unnecessary exchange costs in case of failure.

Recently, various electronic displays have been installed for providing information and advertising. As an example of the electronic display, there is an LED electronic display.

The LED display board is arranged to display a specific letter, symbol, or graphic by arranging light emitting elements (LEDs, hereinafter referred to as "LED elements") in a predetermined form, and then controlling the respective LED elements. It is composed.

On the other hand, such an LED signboard, it is important to maximize the information providing effect and advertising effect by improving the visibility, visibility and attention (注目).

As a method of improving the visibility, clarity and attention of the LED display, there is a method of expressing various colors by increasing the expression color or highlighting the main screen by providing a background screen. In addition, various LED display boards have been developed to implement such a method.

As an example, there is a Korean Patent No. 783759. This technology has a structure in which sub-pixels consisting of three LED elements of red and green (RGB) are arranged between pixels of LED elements (hereinafter referred to as "main pixels").

In addition, a plurality of LED pixel panels comprising an array of main pixels and sub pixels are connected to each other, and a plurality of LED pixel panels connected to each other are driven by corresponding driving drivers.

The conventional LED display panel displays a main screen with main pixels and a background screen of various colors with sub pixels. Thus, the visibility, clarity and attention of the display screen are improved. This maximizes the effect of providing information and advertising.

However, such a conventional LED display board has a disadvantage in that the main pixel cannot be represented only by monochromatic light because the LED element of the main pixel is composed of one kind, and it is impossible to expect high efficiency visibility, clarity and attention due to such disadvantages. The problem is pointed out.

In addition, the conventional LED display board has a structure in which the main pixel and the subpixel of the LED pixel panel are driven by one drive driver, and thus, when any one of the main pixel and the subpixel is stopped, the corresponding driver driver is replaced. There is a disadvantage that must be, because of this disadvantage there is a problem that the maintenance and repair costs are increased.

That is, the conventional LED display board has a structure in which the main pixel and the subpixel are simultaneously driven by one driving driver, although the main pixel and the subpixel of the LED pixel panel are independently driven. Therefore, when any one of the main pixel and the sub pixel is stopped, there is a problem that the corresponding driver must be replaced. As a result, there is a drawback that an unnecessary replacement cost is required, thereby significantly increasing the maintenance and repair cost of the LED display board.

The present invention has been made to solve the above-mentioned conventional problems, the object of which is to configure the main screen can be represented by a multi-color light, to provide an LED signboard that can significantly improve visibility and clarity and attention. There is.

Another object of the present invention is to provide an LED display panel that can maximize the information providing effect and advertising effect by configuring to improve visibility, clarity and attention.

It is still another object of the present invention to provide a LED display board configured to exchange only the corresponding driver when the main pixel and the subpixel are driven by respective driving drivers.

Still another object of the present invention is to configure the main driver and the sub-pixel to replace only the corresponding driver when the function is stopped, thereby reducing unnecessary replacement costs, thereby significantly reducing the maintenance and maintenance costs LED It is to provide an electronic display.

In order to achieve the above object, the LED display panel according to the present invention includes at least one LED pixel panel formed of an arrangement of main pixels and sub pixels, and the LED pixels according to preset data or data input from the outside. An LED signboard having a control unit for controlling main pixels and subpixels of a panel, the control unit comprising: a controller for outputting a control signal for controlling main pixels and subpixels of the LED pixel panel; A signal divider dividing the control signal output from the controller into a first control signal for controlling the main pixel and a second control signal for controlling the subpixel; Main pixel driver drivers installed corresponding to each of the LED pixel panels to drive main pixels of the corresponding LED pixel panel according to a first control signal input from the signal splitter; It is installed corresponding to each of the LED pixel panel, it characterized in that it comprises a sub-pixel drive driver for driving the sub-pixels of the LED pixel panel according to the second control signal input from the signal splitter.

According to the LED display panel according to the present invention, since the main pixel of the LED pixel panel displaying the main screen is composed of a plurality of LED elements, the main screen of various colors can be represented. Therefore, there is an effect that can greatly improve the visibility, explicitness and attention of the main screen.

In addition, the main screen of various colors can be displayed to greatly improve visibility, clarity and attention, thereby maximizing the information providing effect and the advertising effect. Therefore, it is possible to expect the superior information providing effect and the advertising effect compared to the conventional technology that can only represent monochromatic light.

In addition, since the main pixel and the subpixel of the LED pixel panel are individually driven by separate driving drivers, only one of the driving drivers can be easily replaced in case one of the main and subpixels fails. .

Therefore, even if only one of the main pixel and the sub pixel fails, the unnecessary exchange cost can be reduced, unlike in the conventional case in which the main and sub pixel simultaneous driving drivers must be replaced entirely. Thus, there is an effect that can significantly reduce the maintenance and repair cost of the LED sign.

Hereinafter, preferred embodiments of the LED display board according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the configuration of an LED display panel according to the present invention, Figure 2 is a view showing the front portion of the LED pixel panel constituting the LED display plate of the present invention, Figure 3 is a view showing the rear portion of the LED pixel panel. .

First, referring to FIG. 1, the LED display panel of the present invention includes an LED pixel panel 10.

The LED pixel panel 10 is composed of at least one, and the LED pixel panel 10 configured as described above, as shown in FIG. 2, is connected in rows and columns to form an approximately quadrangular shape. In the drawings of the present invention, six LED pixel panels 10 are shown connected in two rows and three columns.

The LED pixel panel 10 includes main pixels 12 and subpixels 14. The main pixels 12 are arranged in a shape in a row and column, and the plurality of main pixels 12 are individually controlled to display a main screen such as a specific character, symbol, or graphic.

On the other hand, the main pixel 12 is composed of a plurality of LED elements 12a, 12b, as shown in FIG. In particular, it consists of two LED elements 12a and 12b.

Accordingly, the main pixel 12 includes three colors including two colors corresponding to the two LED elements 12a and 12b and one color that can be represented by the two LED elements 12a and 12b. Can express color

As a result, the main pixel 12 can express the main screen of various colors, thereby improving the visibility, explicitness, and attention of the main screen as much as possible. Therefore, the effect of providing information and advertising can be maximized. In particular, it can be expected that the superior information providing effect and the advertising effect compared to the conventional technology that can only express monochromatic light.

On the other hand, the LED elements 12a and 12b of the main pixel 12 are composed of two elements selected from three LED elements of red and green (RGB). Preferably, it is preferable that the LED element 12a emits red light and the LED element 12b emits green light. Therefore, it is preferable that the main pixel 12 be configured to display yellow, which is a combination color of red and green and red and green.

The subpixels 14 are composed of three LED elements 14a, 14b, and 14c of red, green, and blue, and the subpixels 14 thus configured are equally spaced between the main pixels 12.

These subpixels 14 are individually controlled with the main pixels 12 to display a background of various colors. Therefore, the visibility, clarity and attention of the main screen are further improved, thereby maximizing the information providing effect and the advertising effect.

On the other hand, although the subpixels 14 are provided between the main pixels 12, as shown in FIG. 2, the subpixels 14 may also be installed outside the main pixels 12.

In particular, it may be installed along the circumference of the LED pixel panel 10 at regular intervals from the main pixels 12. Therefore, a background screen may be displayed on the edge of the LED pixel panel 10. This further increases the information providing effect and the advertising effect.

Referring back to FIG. 1, the LED display board of the present invention includes a power supply unit 20 and a control unit 30 for controlling the LED pixel panel 10.

The power supply unit 20 receives an external commercial power source and provides it to the LED pixel panel 10.

The control unit 30 includes a controller 32 and a signal distributor 34. The controller 32 includes a microprocessor and a driving circuit, and outputs a control signal for controlling the LED pixel panels 10.

In particular, a control signal for controlling the main pixel 12 and the subpixels 14 according to preset data is output or for controlling the main pixel 12 and the subpixels 14 according to externally input data. Output a control signal.

The signal distributor 34 branches the control signal output from the controller 32 to each LED pixel panel 10.

In particular, the control signal of the controller 32 is branched, but the first control signal C1 for controlling the main pixel 12 of the LED pixel panel 10 and the second control signal for controlling the subpixel 14. After separating into (C2), each of the separated first and second control signals C1 and C2 is input to each of the main pixel driver drivers 36 and the subpixel driver drivers 38, which will be described later.

Referring again to FIG. 1, the LED display board of the present invention includes a plurality of main pixel driver drivers 36 and a plurality of subpixel driver drivers 38.

The plurality of main pixel driving drivers 36 are installed to correspond to each LED pixel panel 10 and drive the main pixels 12 of the corresponding LED pixel panel 10.

In particular, the main pixels 12 of the LED pixel panel 10 are turned on or off according to the first control signal C1 input through the signal splitter 34. Therefore, the main pixels 12 of each LED pixel panel 10 are blinking to display the main screen.

The plurality of subpixel driver drivers 38 are installed to correspond to each LED pixel panel 10 and drive the subpixels 14 of the corresponding LED pixel panel 10.

In particular, the subpixels 14 of the LED pixel panel 10 are turned on and off in accordance with the second control signal C2 input through the signal splitter 34. As a result, the subpixels 14 of each LED pixel panel 10 are blinking to display a background screen.

According to the present invention having such a configuration, since the main pixel 12 of the LED pixel panel 10 displaying the main screen is composed of a plurality of LED elements 12a and 12b, the main screen of various colors can be represented. Therefore, the visibility, clarity and attention of the main screen can be greatly improved.

In addition, the main screen of various colors can be displayed to greatly improve visibility, clarity and attention, thereby maximizing the information providing effect and the advertising effect. Therefore, superior information providing effect and advertisement effect can be expected as compared with the conventional technology which can express only monochromatic light.

In addition, according to the present invention, since the main pixel 12 and the sub pixel 14 of the LED pixel panel 10 are driven by separate drive drivers, any one of the main pixel 12 and the sub pixel 14 may be used. In case of fault, only the corresponding driver can be replaced easily.

Therefore, even if only one of the main pixel 12 and the sub pixel 14 fails, the replacement cost of the parts can be reduced as much as possible, unlike the conventional method in which the drivers for driving the main and sub pixel 14 are replaced. As a result, the maintenance and repair cost of the LED display board can be greatly reduced.

Although the preferred embodiments of the present invention have been described above by way of example, the scope of the present invention is not limited to these specific embodiments, and may be appropriately changed within the scope of the claims.
