Description

Product information display apparatus

The present invention relates to a product information display device, and more particularly, to a luxury information display device that can confirm the authenticity of the product and can display the product information.

In general, when purchasing goods such as world-class luxury goods or famous brands, consumers or buyers think that the goods they buy are genuine, but they are not capable of identifying whether the goods are genuine or not. It is impossible to identify the authenticity of a well-known brand.

The distinction between the world's luxury goods and famous brands is distinguished through the spelling of the logo for each item, the sewing seam, the material buckle, and the internal composition. If the buyer asks for a confirmation of authenticity, it shows a tag and a guarantee letter which distinguishes the imported imitation from the authenticity, but even this is difficult to distinguish the genuine and the counterfeit goods, and the goods cannot distinguish the genuine and the counterfeit goods. .

Recently, when looking at the news through the media, it is easy to see the articles that counterfeit goods are sold in various duty-free shops and department stores, which are believed so far, so it is difficult to distinguish between genuine and counterfeit goods at this time.

As a result, consumers are inferior in the scarcity and value of genuine goods by purchasing counterfeit goods that are inexpensive and almost indistinguishable from genuine products.

An object of the present invention is to put the RFID tag in the luxury goods during the production of luxury goods, when the proximity of the tag reader unit can be informed by the display and voice information of the goods so that the authenticity of the goods can be authenticated luxury goods. At the same time, a card type product information display device having a simple structure and being easy to carry is provided.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a card-type product information display device according to an embodiment of the present invention. As shown in FIG. 1, the card type product information display apparatus includes a tag reader 110 for transmitting and receiving an RFID tag, a memory 120 for storing an encryption algorithm, a display 140 for displaying information, and the tag reader. The control unit 130 controls the unit 110, the memory unit 120, and the display unit 140.

For reference, although the encryption algorithm is separately stored in the memory unit 120, the encryption algorithm may be directly applied to the circuit of the controller chip. In addition, it is preferable that data such as an encryption algorithm stored in the memory unit 120 is separately encrypted by another encryption algorithm so that the control unit can decrypt it.

The controller 130 includes a battery unit 150 and an on / off switch configured to control power supply to each of the tag reader unit 110, the memory unit 120, the controller 130, and the display unit 140. It is preferable.

In this embodiment, the speaker unit 160 and external terminals are added. The external terminal connected to the control unit 130 is connected to an external server through a specific program of the computer to transmit the contents stored in the memory unit 150 to an external server or data or product data for the authentication key transmitted from the external server. It may be stored in the 120 or to be directly displayed on the display unit 140. In addition, when a special signal is received by the tag reader unit 110 without an external terminal, the control unit may store the signal data in the memory unit, and generate a specific signal in the tag reader unit to perform wireless communication with an external device. In some cases, the wireless communication may be performed by a separate wireless communication means.

The tag reader 110 may be a RFID tag using a frequency band of 13.56 MHz, 433 MHz, or 900 MHz, and a ZigBee reader used for 2.45 GHz as a means for wirelessly communicating with an RFID tag.

The memory unit 120 is configured of a single flash memory or a nonvolatile memory such as an EEPROM, a flash ROM, and the like, and stores information on an RFID tag interpreted by the card type product information display device. In addition, the memory unit 120 stores a cryptographic algorithm necessary for authenticating and decrypting information received from the RFID tag, and also stores luxury data according to a use state.

It is preferable that the display unit 140 uses a flexible substrate which does not damage the card type product information display device, and uses a micro liquid crystal cell LCD formed of micro sized cells.

The micro liquid crystal cell first deposits transparent electrodes on the upper and lower substrates by sputtering. Plastic substrates are used for the upper and lower substrates. Due to the weak plasticity of the heat, the upper and lower substrates are prevented from being deformed by the post-process after the upper and lower substrates on which the transparent electrodes are formed. A patterned transparent electrode is formed by using a photolithography process on the entire surface where the transparent electrode is deposited. Next, a spacer is sprayed onto one of the upper and lower substrates, and an encapsulant is applied to the other substrate. The material of the encapsulant is coated using a UV-curable or heat-curable polymer except for the space where the liquid crystal mixture is to be injected. Next, the spacer and the upper and lower substrates on which the encapsulant is formed are attached to each other, and the encapsulant is cured by UV exposure or heat treatment to form a semi-LCD cell. Semi-LCD cells are cut and formed into independent cells. Next, instead of the process of injecting a liquid crystal, a micro pixel mixture, which is a mixture of a liquid crystal and a curable polymer, is injected into an independent cell.

The liquid crystal microcell is formed by mixing a curable polymer having a suitable viscosity and a liquid crystal. When mixed, the curable polymer surrounds the surface of the liquid crystal. A micro cell having a size of 5 to 200 μm is formed. The curable polymer surrounding the liquid crystal forms a wall while forming a boundary with the polymer of the adjacent microcell. The concentration of the curable polymer affects the wall thickness of the independent cell. For example, the lower the concentration, the narrower the wall thickness of the cell. In the process of mixing the liquid crystal and the curable polymer, heat treatment may be performed according to viscosity. The mixed micro pixel mixture is then injected into the cell. The micro pixel mixture may be heat treated within the range of 25 ° C. to 75 ° C. for smoother injection. When the cell is filled with the micro pixel mixture, the cell is sealed and the curable polymer is cured. When UV curing, a plurality of light sources may be placed on both sides of the cell for uniform curing. As the UV or thermosetting polymer is cured, the curable polymer layer formed on the transparent electrode serves as an alignment layer. Next, a polarizer (transparent plate, reflective plate, or semi-transparent plate) is attached to the cell surface, and a tab is connected to allow voltage to be applied to the transparent electrode.

The battery unit 150 supplies power required for operating the display unit 140 using a lithium-polymer secondary battery or the like.

The speaker unit 160 is a thin film type speaker, and the piezoelectric film, which is a key material in speaker manufacture, uses mechanical, physical, and chemical methods for surface treatment.

Mechanical and physical methods are methods using ionic materials such as plasma, ion beam, arc, ion implantation, and media blaster. Chemical methods are chemical and chemical methods using Na complex salt reacting with fluorine compounds. The plating method is used. Special treatment methods, such as mechanical, physical, and chemical methods, increase the roughness of the piezoelectric film surface or change the chemical structure, thereby increasing adhesion to the electrode thin film deposited in a later process. The conductive material applied to both sides of the piezoelectric film is a mixture of one or more of platinum, gold, silver, copper, chromium, nickel, aluminum, ITO, IGO, AGO and sulfur compounds, and may include all other common conductive materials. have.

In addition, certain solutions and materials may be added and mixed to increase the adhesion of the conductive material. The thin film type speaker may be formed by overlapping two sheets of a film type speaker unit generated by applying a conductive material to both surfaces of the piezoelectric film. The bonding method is carried out in a vacuum by mixing one or two or more of a method such as heat, pressure, conductive adhesive and laminating. The method by heat is to apply heat in the range of 70 ° C. to 150 ° C., the pressure is 50 g / cm 2 to 50 kg / cm 2, the conductive adhesive is 0.5 μg to 500 μg, and the laminating is 70 ° C. to 150 ° C.

In the film-type speaker unit, the conductive material is evenly distributed in the film so that the conductive polymer or metal evenly transmits the acoustic signal to the piezoelectric film when the current is applied, and the piezoelectric film vibrates finely by the acoustic signal received evenly. Will be generated. That is, the film type speaker unit vibrates finely by the current transmitted evenly to the film type speaker unit, thereby converting the electrical signal into sound.
