An eye-catching LED having a higher luminous intensity than the display LED constituting the display screen is arranged so as to be located between symbols or characters, pictures, or symbols. It has the effect of being able to increase Disclosure of the invention

The present invention has also been made in view of the above-described problems of the related art, and provides an LED display device that can enhance the eye-catching effect of an LED display device and obtain a high information transmission effect. It is intended to do so.

For this reason, according to the present invention, in an LED display device including a plurality of display LEDs and having a display screen for displaying a message such as a character or a picture symbol, the entire display panel is regularly and vertically and horizontally arranged in a matrix. A low-brightness LED multi-colored luminous sphere or LED monochromatic luminous sphere is arranged in the shape of After arranging LED multi-colored spheres or LED single-colored spheres, first turning on or flashing the high-brightness LED multi-colored spheres or LED single-colored spheres to display characters, graphics, symbols, and videos for eye-gaze capture , Low brightness The first feature is that character information to be transmitted is displayed by lighting or blinking the LED multicolor light emitting ball or LED single color light emitting ball. The second characteristic is that the low-brightness LED multi-color light-emitting spheres or LED single-color light-emitting spheres are arranged regularly and in a matrix in gaps between the arrangements. BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 is a front view showing a schematic structure of an LED display device according to the present invention, FIG. 2 is a circuit block diagram of the LED display device according to the present invention, FIG. 3 is a flowchart showing a control method of display data, and FIG. 4 to 6 are front views showing display examples of the LED display device according to the present invention. BEST MODE FOR CARRYING OUT THE INVENTION

As an embodiment that effectively utilizes the features of this LED display device, for example, as shown in FIGS. 4 and 5, a low-brightness LED 1 displays a Christmas picture, There is a method of blinking the high-brightness LED 4 located in the outline or inside like an illumination in the picture, and performing eyewear.

In the present embodiment, first, a graphic or a moving image is displayed on the entire surface of the panel with a high-brightness LED to attract the attention of a consumer, and then, character information to be transmitted is displayed with a low-brightness LED. By doing so, reliable information can be transmitted. Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the LED display device according to the present invention is An LED matrix cut 2 (16 x 16 dot configuration), on which a single LED luminous bulb 1 (indicated by 〇 in the figure), which is composed of multiple substrates and has a plurality of display LEDs, is arranged in characters. The display screen 3 is configured to display 6 characters of 2 × 3. Each LED matrix sut 2 can display a part or the whole of an image such as a character, a picture, or a symbol as information to be transmitted by the LED monochromatic luminous bulb 1.

That is, the display screen 3 is configured by arranging low-brightness LED single-color light-emitting spheres 1 regularly and horizontally in a matrix. Here, in the present embodiment, furthermore, a high-brightness LED multi-colored luminous sphere or an LED single-color luminescent sphere (matrix in FIG. ) Are used as gaze-capturing LEDs. That is, as shown in FIG. 1, high-brightness LEDs 4 are arranged in a lattice in a low-brightness LED matrix unit 2. In other words, although the screens are the same, they appear on the same screen, but the message display surface 3A displays messages using characters and picture symbols using low-brightness LEDs, and high-brightness red, blue, green, white, yellow, light blue, etc. The LED multi-color light-emitting sphere or the LED single-color light-emitting sphere is arranged so as to overlap with the eye-catching display surface 3B (see FIG. 2). The illuminance of the low-brightness LED is 2300 (m cd) at a distance of 10 cm, and the illuminance of the high-brightness LED is about twice this.

FIG. 2 is a block diagram showing a control circuit of the present apparatus. Here, the controller 5 is configured by connecting a microprocessor (CPU) 6, a ROM 7, a RAM 8, and an input / output interface (10) 10 to each other by a data device 9. The microprocessor (CPU) 6 controls the entire system and enters the application program. This is a data conversion unit for converting the input text character data and catch decoration data into display data. The ROM 7 stores a program for system control, a message display data processing program, an ornament decoration data processing program, and font data such as characters, pictures, and symbols. The RAM 8 is backed up by a battery (not shown), assists in display control, and stores text character (font) data and the like. 11 is a message display surface driver for driving and driving the message display surface 3A, and 12 is an eye-catcher display surface driver for driving and driving the eye catch display surface 3B.

Next, the screen display method of the apparatus according to the present embodiment will be described by taking as an example the display method of the picture of the Christmas tree shown in FIGS. As shown in the flow chart of Fig. 3, first, the eye catch data is transferred to the memory (S1), and the high-brightness red, blue, green, white, yellow, light blue, etc. LEDs on the eye catch display surface 3B are displayed. Light or blink a multicolor luminescent ball or LED single color luminescent ball to display a character 'graphic' symbol animation for gaze capture (S 2). In this case, high-brightness LED 4 is red, blue, green The use of a single color luminous sphere, such as white, yellow, or light blue, can provide an extremely high eye-catching effect. Next, it is determined whether the eye-catching display is completed (S3). If the display is completed, the message data is transferred to the memory (S4). The low-brightness LED light-emitting bulb on the message display surface 3A is turned on or blinks. (S5) For example, only the low-brightness LED 1 is turned on to display information to be transmitted (here, character information of “Christmas sale”). Next, it is determined whether or not the message display has ended (S6). If the message display has ended, the process returns to (S1) and repeats the above operation. On the other hand, if the display of the eye catch display (S3) or the display of the message (S5) is not completed, The indication is repeated.

In addition, as shown in Fig. 6, only the high-brightness LED 4 is used, and the number of LEDs that are turned on and blinking is gradually increased to create a moving image that looks like a fireworks opening. This also results in a high eye catching effect.

The gist of the present invention lies in that high-brightness LEDs are regularly arranged over the entire surface of a display panel composed of low-brightness LEDs. The arrangement density is not limited to the above, and the arrangement density may be varied. Further, in the above embodiment, an LED display device having a 6-character configuration of 2 rows and 3 columns has been described, but the present invention is not limited to this, and an LED display device having a plurality of rows and a plurality of rows and a plurality of rows is provided.
