BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic display system using a light emitting diode as a light emitting device, and more particularly, to a method of arranging a light emitting diode and an electronic display system having a light emitting unit according to the arrangement.

Light Emitting Diode (LED) is a light emitting diode that emits light, and there are many kinds of colors and sizes such as red, green, blue, and white, but LEDs that use red and green light emitting diodes are mainly used. Due to the semi-permanent life of more than 50,000 hours and low power consumption, the application range is being expanded to the state-of-the-art devices that will contribute greatly to the future advertising industry.

The LED display board using the LED as a light emitting device implements an output screen of the display board by arranging a plurality of LEDs in a tiled manner and lighting only a part of the LEDs. Currently, such an LED display panel is composed of a plurality of panelized pixel panels, and the pixel panel is composed of a plurality of pixels arranged horizontally and vertically.

Such an LED signboard is illustrated in FIG. 1 to illustrate a conventional monochromatic light emitting 2D LED signboard and a multicolored light emitting 2D LED signboard. In general, the LED signboard combines a plurality of pixel panels 10 to emit light ( 1), the pixel 100 constituting the pixel panel 10 is composed of one light emitting diode or a plurality of light emitting diodes.

The example shown in FIG. 1 is a two-dimensional LED display panel having a light emitting unit 1 composed of 32 × 32 pixels, and two pixel panels 10 consisting of 16 × 16 pixels are horizontally coupled to each other. It is composed.

In this case, the pixel 100 includes one light emitting diode, or two light emitting diodes having different light emitting colors, or three.

As illustrated, when the pixel 100 is formed of only the light emitting diodes R emitting red, all images output through the light emitting unit 1 become red, and the light emitting diodes R emitting green and the green When the pixel 100 is formed of a light emitting diode G that emits light, the image output through the light emitting unit 1 is divided into three types of red, green, and yellow, and the light emitting diodes R emitting green and the green light are emitted. When the pixel 100 is formed of the light emitting diodes G emitting light and the light emitting diodes B emitting blue light, the image output through the light emitting part 1 becomes full color.

That is, in the case of the two-dimensional LED display board, the emission color of the output image is determined according to which color of the light emitting diodes constituting the pixel 100 of the light emitting unit 1 emits light and how it is configured.

Since there are 1024 pixels 100 of the light emitting part 1 composed of 32 × 32 pixels as shown in the drawing, if the pixel 100 is composed of one light emitting diode to output a single color, 1024 light emitting diodes are required. If the pixel 100 is composed of two light emitting diodes for outputting three colors, 2048 light emitting diodes are required, and if the pixel 100 is composed of three light emitting diodes for outputting full colors, 3072 light emitting diodes are used. The diode is taken.

Therefore, the multi-color light emitting two-dimensional LED display board, which is not monochromatic light emission, requires two times the number of light emitting diodes in the case of three colors, and three times the number of light emitting diodes in the case of full color. There is a problem that takes a lot, and there is a problem that the manufacturing cost of the display board is high due to the large number of use of light emitting diodes.

In addition, as shown in FIG. 2 to illustrate the outputs of the conventional monochromatic light emitting 2D LED sign and the tricolor light emitting 2D LED sign, FIG. 2A shows that the pixel 100 emits red light. In the case of a red light emitting two-dimensional LED display board composed of only the image output through the light emitting unit 1 becomes red or the ground color becomes red.

Therefore, there is a problem that the expressive power is lowered and monotonous due to the relationship that the color expressed is red only.

2 (b) in the case of the three-color light emitting two-dimensional LED display panel, in which the pixel 100-1 includes a light emitting diode R emitting red light and a light emitting diode G emitting green light, the light of the pixel 100-1 is emitted. By controlling the on / off of the diodes R and G, the color or the background color of the output image may be determined.

That is, as shown in FIG. 2B, when only the light emitting diodes R emitting red of the light emitting diodes R and G of the pixel 100-1 are turned on, the output image is red. When only the light emitting diode G emitting green light among the light emitting diodes R and G of the pixel 100-1 is turned on, the output image becomes green, and Among the light emitting diodes R and G, when only the light emitting diode R emitting red light and the light emitting diode G emitting green light are turned on, the output image becomes yellow.

As a result, the three-color light emitting 2D LED display board has the same number of actual pixels as the monochromatic light emitting 2D LED display board, but the number of light emitting diodes as the light emitting device is doubled.

Therefore, the three-color light emitting 2D LED display board has a relatively high expressive power and is more natural than the monochromatic light emitting 2D LED display board, but the manufacturing cost is high and the power consumption is relatively high because the light emitting diode, which is a light emitting device, requires twice as much. There is this.

Therefore, the present invention was devised to solve the problems of the monochromatic light emitting 2D LED display board and the multicolored light emitting 2D LED display board, and the output of an image output while using the same number of light emitting diodes as the monochromatic light emitting 2D LED display board. This natural and versatile output enables the visual effect to be higher than that of the conventional monochromatic light emitting 2D LED signboard and to reduce the production cost by reducing the use of expensive LEDs in half compared to the conventional trichromatic 2D LED signboard. It is an object of the present invention to provide a method of arranging a light emitting diode and a signboard system of a two-dimensional LED signboard, which can produce a three-color output while reducing consumption.

In addition, it is convenient to use the remote control to control the display board, and when using the remote control to overcome the limitations of the installation position by exposing and separating the infrared receiver to the outside, the outer case can be easily according to the size of the light emitting unit The purpose is to provide a display system that can be manufactured.
