BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an active color pattern using a light emitting device display and an apparatus for generating the same, and more particularly, to an active color pattern and a generating device capable of changing display information contents in real time using an LED display function as an active device. will be.

Recently, most products in the market are printed with a bar-code composed of lines of various thicknesses to indicate product information such as product type and price. As shown in FIG. 1, the bar code is composed of a thick line, a thin line, a double line, and the like to represent numeric data encoded with commodity information.

1 is a view showing a bar code pattern according to the prior art, the country code as a code for identifying the country in the case of Korea using a "880", a code for assigning each manufacturer with a code assigned to the manufacturer or salesman, manufacturer code, Commodity code, which is a code that identifies and assigns each product by a company that has been granted a manufacturer code, and a code that verifies an error of a bar code, consists of a verification code that is a combination of the preceding numbers.

The barcode was first documented by Wallace Flint of Harvard University, USA, in 1923, writing a paper on `` Supermarket Calculation Automation. '' At the end of 1940, Joe Woodland and Bernie Silver studied the automatic processing of food prices in the form of small shooting targets, in which the bars and spaces, so-called 'bull's eye codes' are concentric. This is conceptually the same as today's barcodes. Also, in 1973, the U.S. Supermarket Ad Hoc Committee began to become common when the Universal Product Code (UPC) was established as the food industry standard. The United States enacted these UPCs and successfully used them in supermarkets in the United States and Canada, and in Europe they were stimulated by 12 countries to adopt the 13-digit European Article Number (EAN) code and symbol at the end of 1976.

There are two major international standard barcodes. There are EAN codes used by more than 100 countries around the world and UPC codes used in the United States and Canada. Korea also uses EAN code. In the past, it was used as the KAN code in Korea, but now it is called EAN KOREA externally in Korea because it uses the EAN code as the official name.

Specifically, Korea joined the EAN in 1988, was given the country code 880, and in the same year, the Korean Common Article Code (KAN) system was established, and each manufacturer code is registered at the Korea Distribution Information Center. There is a barcode symbol attached to it. Here, the EAN code is an abbreviation of the European Article Number and is used by EAN International (International Product Code Management Association).

On the other hand, the operation principle of the bar code is as follows. First, the bar code is composed of thick black bars on a white background. The bars represent binary numbers 0 and 1, and the array of bars represents decimal numbers from 0 to 9. After all, the numbers written under the bar code are shown in bold and thin bars. The computer makes it difficult to recognize the numbers we write, so we can use the bar code to recognize them as binary numbers.

The scanner uses a scanner to read the information contained in the bar code. The black bar portion of the bar code absorbs light and reflects a small amount of light, while the white part between the black bar reflects a large amount of light. The difference in the amount of reflected light passes through the analog-to-digital converter inside the scanner, which is converted into an electrical signal based on the intensity of the light, which is then input to the computer with 0s and 1s, allowing us to recognize letters and numbers. Will appear.

On the other hand, for general business purposes, a business card may be printed with a URL (Uniform Resource Location) such as an Internet homepage address or an e-mail address. The Internet homepage contains the contents of the company's public relations, and an Internet user interested in the company reads the company's public relations contained in the Internet homepage and attempts to contact the e-mail address when inquiries are made. In addition to business cards, there are cases in which a particular company's Internet homepage address or other URL is printed in an advertisement column such as a magazine or a newspaper, and sometimes an internet homepage address is also printed in a publication.

If a user wants to access the URL printed on the business card, he or she must type the URL printed on the business card with the keyboard. Or, if the business card has an e-mail address printed on it, a user who wants to send a letter to that e-mail address must type in the e-mail address.

However, Internet homepage addresses or e-mail addresses do not consist of one or two letters, but generally consist of dozens or tens of letters. This has the disadvantage of being cumbersome for the user to enter the address.

As described above, using a bar code which is widely used now can represent only a small amount of data. That is, the barcode has a limit on the number of characters that can be encoded and cannot be freely expressed.

In order to solve this disadvantage, US Patent Publication No. USP5,869,828 (name of the invention: color and shape system for encoding and decoding data) has been proposed. USP 5,869,828 is a method and system for encoding / decoding character data using a color figure, and can display information of a product by printing a color figure with a simple configuration on the surface of the product.

2A and 2B are diagrams illustrating a gray pattern code and a color pattern code, respectively, according to the prior art.

Referring to FIGS. 2A and 2B, the color pattern code service photographs (recognizes) a color code / gray code marked on a print medium or an image medium with a terminal (PC camera, PDA, mobile phone, etc.) supporting a camera function. It is a service that provides contents and information from WAP and video by linking offline and online.

The color code refers to an image code composed of a matrix of cells represented by various colors, and the gray code illustrated in FIG. 2A has three brightnesses of black, gray, and white. Refers to an image code composed of a matrix of cells represented. In addition, a numeric code is a code for a complementary role of the image code, and refers to a numeric code for which a service is provided as an input through a keyboard for a user without a camera.

In addition, the color code and the gray code are image codes that are infinitely expandable by increasing horizontal cells, vertical cells, and color used, and may be generated in various kinds according to a matrix form. In addition, the color code / gray code is an image code composed of a matrix of rectangular cells represented by a specific color, and is designed in a popular and open form so that anyone can easily create and use it anytime, anywhere. In addition, it is possible to respond flexibly to the adjustment of information usage rights.

In addition, since the color code / gray code was developed based on an inexpensive general low resolution camera, it does not need an expensive dedicated scanner or a separate input device such as a bar code, and can be effectively used as a PDA or a mobile phone. In addition, the color code / gray code can be used in a wide variety of applications because it can be easily moved between the offline environment, as well as online and offline environments, online and online environments and mobile environments and online environments, mobile and mobile environments. .

In addition, since the color code / gray code can input various information to the recognition terminal only by recognizing the color code / gray code through a camera of a general terminal or a PC, an input replacement function of digital information is performed.

The color code / gray code is an advanced computer recognition technology that increases the amount of information by 10 times or more than a conventional one-dimensional bar code, and combines various colors in horizontally and vertically arranged squares, thereby recognizing various information. The color code / gray code interface system is a system that receives color encoded information with a general PC camera and decodes it, and provides information corresponding to the information of the color code / gray code.

The color code / gray code analyzes a color code pattern image input through a PC camera / mobile phone camera, extracts a corresponding code value, and requests an application type and an application server address related to the code from the color code / gray code platform. Then, the received data is delivered to the corresponding application client of the terminal.

Since the color code / gray code can be recognized by a general-purpose reader such as a general low resolution PC camera and a mobile phone camera, it does not need an expensive dedicated scanner or a separate input device like a bar code, and can be effectively used as a PDA or a mobile phone. It is available.

The color code / gray code has the following difference from a barcode. That is, the same code system, but the bar code is a black and white bar, while the color code is a matrix using a variety of colors. Since color is used, more information can be expressed compared to barcodes that use only black and white, and color codes can be used in general PC cameras or cameras attached to mobile phones compared to barcode readers (recognizers). Use

Meanwhile, the recent development of the IT industry provides a wide variety of information beyond the concept of space limitation to the general user, and some of the information has the effect of saving time and space at the same time as the service is performed in real time. This quality service can be expanded and implemented because the user's own equipment, for example, a mobile phone, improves performance at a very high speed.

These various conditions have created a new industry, and the information service (content business) that meets various needs is increasing very rapidly for users who use the current mobile communication or Internet service network.

On the other hand, the rapid expansion of the market intensifies competition among service providers, and consumers are often confused about information selection due to excessive information. In order to prevent such confusion, researches are being conducted to select and manage individual effective (preferred) contents.

In conclusion, under the flood of information, operators should deliver various information to consumers quickly, and consumers should be able to get the information they need easily and quickly.

This means the development of interface technology, for which various technologies have been developed. Among them, the most comfortable interface for users is the use of vision. Despite the advantages that the vision interface can be serviced at a very low level of convenience and user education, it has been very late. This is because equipment equipped with a camera is essential for the vision interface.

Recently, due to the development of camera-related technology and the lowering of price, cameras are attached to IT equipment very quickly. Currently, it is common to sell cameras mounted on mobile phones. Barcodes are the most common vision interface, but they have been applied to systems rather than individuals, and recently, patterns printing technology is applied.

The interface using the pattern is characterized in that the user can easily access the information with minimal manipulation provided that the device is equipped with a camera. This advantage is expected to spread the pattern interface very quickly.

However, the current pattern interface can provide a variety of information by generating a number of combinations through the combination of color and pattern, but there is a problem that can not escape the physical barriers of printing and attachment. This is a fatal problem when requesting information in real time.

In general, in the case of an external communication network, information can be transmitted in various ways such as directly connecting to the Internet or a mobile communication network PC. All of these methods are well known, and a separate description of the operation will be omitted.

Referring to FIG. 5, an apparatus for generating an active color pattern using a light emitting device display according to an exemplary embodiment of the present invention will be described using an example of directly connecting a PC using a serial port.

First, when the RS232C port (DB9) of the PC serial port and the DB9 terminal of the ACP are connected by a cable to transmit data, the input terminal (Pin 8, 14) of the MAX232CPE which is an IC 310 dedicated to RS232C communication in the ACP circuit. Is entered.

The signal input in this way is a signal that changes to +/- level, but this signal is converted into a TTL level signal from the MAX232CPE 310 to the dedicated input terminals RC6 and RC7 of the microcomputer PIC16F877 (320). Is entered. When a signal is input to the microcomputer 320, the microcomputer 320 changes the input signal into a signal capable of turning on the LED.

First, LED lighting data according to color is generated. The LED lighting data is as follows: R: HLL, G: LHL, B: LLH, RG: HHL, RB: HLH, GB: LHH, RGB: HHH.

When the color is determined as described above, the microcomputer 320 determines color data for each of the coordinates A1 to A7, B1 to B7, C1 to C7, D1 to D7, and E1 to E7 of each LED, and changes the changed signals to E7, E6, E5,... , E1, D7, D6,... , C1,... , B1,... The signal is output to the signal processor 330 in the reverse order of A1.

When the microcomputer 320 sends a signal to the signal processor 330, three output ports are used. The microcomputer 320 outputs a total of 94 data, clock signals, and output enable signals. For each port, RB0 represents data and RB1 represents clock. , RB2 outputs an output enable signal.

On the other hand, the external communication network 310 and the microcomputer 320 according to an embodiment of the present invention has a built-in power supply circuit. The power supply circuit receives 7-12V DC power from the outside for stable supply of power and converts it to 5V DC power using the regulator 360.

6 is a circuit diagram of a signal processor of an active color pattern generation apparatus using a light emitting device display according to an exemplary embodiment of the present invention.

Referring to FIG. 6, the signal processor 330 according to an embodiment of the present invention converts a signal of the microcomputer 320 transmitted in series into a parallel signal, and also stores an output signal so that the next signal is input. It keeps its output until.

The elements constituting the signal processor 330 may include, for example, CD4094 and CD40174, where CD4094 is an eight-stage shift register 331a, 331b, 331c, and 331d having a three-phase output. CD40174 is a hexa type D flip-flop 332a to 332f.

Input terminals of the shift registers 331a, 331b, 331c, and 331d include a data terminal and a clock terminal. The shift registers 331a, 331b, 331c, and 331d allow the shift registers 331a, 331b, 331c, and 331d to operate when the output enable and strobe terminals become high logic values. do.

The microcomputer 320 outputs data in the reverse order from the last LED, E7 to A1, because the first signal appears at the last terminal and the last signal appears at the first terminal. The data signal is input to the data terminal of the first shift register 331a at RB0 of the microcomputer 320, and the clock signal output from the RB1 terminal of the microcomputer 320 is all shifted. It is input to the clock terminals of the registers 331a, 331b, 331c, and 331d.

When the microcomputer 320 outputs one bit of data through RB0 and outputs a clock through RB1, data is stored in the first terminal of the first shift register 331a. When data and a clock are input to the microcomputer 320, the data is stored at the first terminal of the shift register 331a, and the data stored at the first terminal is shifted to the next terminal. Shift).

The remaining 30 LEDs consume a total of 90 pieces of data, each of three terminals R, G, and B. Therefore, when 94 data (Data) and a clock (Clock) are output from the microcomputer (320), the corresponding output signal appears at the output terminals of the shift registers (331a to 331d). This signal is transmitted to the input terminals of the D flip-flops 332a to 332f, and the D flip-flops 332a to 332f output a signal whose clock is the output signal of the microcomputer 320. This output is stored until the next signal is input to the D flip-flops 332a to 332f. The output signals of the D flip-flops 332a to 332f are input to the base terminals of the transistors of the LED driving circuits 341a, 341b, and 341c through input resistances.

7 is a circuit diagram of an LED driver of an active color pattern generating apparatus using a light emitting device display according to an exemplary embodiment of the present invention.

The LED display unit 340 of the active color pattern generating apparatus using the light emitting device display according to the embodiment of the present invention is composed of LED driving circuits 341a, 341b, and 341c and LEDs 342a, 342b, and 342c.

Referring to FIG. 7, the LED driving circuits 341a, 341b, and 341c according to the exemplary embodiment of the present invention amplify the LED control signal output from the signal processor 330 described above to provide the LEDs 342a, 342b, and 342c. It is to supply enough electric current to emit light with necessary illumination.

The LED driving circuits 341a, 341b, and 341c may be configured with the transistor Q, and use the amplification principle of a general transistor.

Specifically, the current control capability (collector current) of the transistor Q is given by the current x amplification h _fe flowing into the base terminal. The collector current in the LED driving circuits 341a, 341b, and 341c is established as follows.

That is, the D flip-flop when said (332a, 332b) to that of the 5V DC output voltage of the CD40174 TTL level, a bias voltage of the transistor (Q) is approximately 0.66V, h _fe is given as about 200 And the current Ic emitted from the collector to the emitter is Ic = [(5V-0.66V) / 3k] x h _fe = 0.263A = 263 mA. At this time, since the driving current of the LED is 20 mA, the LED driving circuits 341a, 341b, and 341c sufficiently drive the LEDs, so that they can emit light with appropriate illumination.

Referring again to FIG. 4B, the LEDs 342a, 342b, and 342c have three types of LEDs arranged as shown in FIG. 4B. In this case, C4 represents an infrared receiving module, A1, A7, E1 and E7 represent infrared light emitting LEDs, and the rest represent three color light emitting LEDs.

8A and 8B are circuit diagrams of an infrared transmitter and an infrared receiver of an active color pattern generation apparatus using a light emitting device display according to an exemplary embodiment of the present invention, respectively.

At this time, when the bias current is input to the base of the transistor through the input resistor 3kV, the transistor is electrically connected between the collector and the emitter by the amplifying action. At this time, a voltage drop of about 0.3V occurs. Therefore, when the transistor repeats the on / off according to the base control current, the infrared transmitting LED also emits an infrared signal by emitting light according to the signal.

The infrared receiver 352 converts an infrared light signal transmitted from an infrared transmitter of another device into an electrical signal. At this time, since the infrared receiving module 352 used has a built-in amplifier and a noise filter therein, it selectively amplifies its signal and outputs it at the TTL level regardless of external interference.
