Card type receiver and manufacturing method {Fabrication method for card type reciever and the same}

The present invention relates to a receiving apparatus, and more particularly, to a card-type receiving apparatus and a manufacturing method which can check information input and output through an electronic card through vibration and light.

The most commonly used contact type IC card is a common type of electronic card, which forms a space for mounting a predetermined smart IC chip on the surface of the same plastic card as a credit card, and then has its own arithmetic function. Is a microcontroller unit (MCU, 1k to 64kbytes), an operating system (COS), and an IC chip incorporating an EEPROM as a safe storage area. When the IC card is inserted into an interface device (IFD), the card contacts with the contact of the IFD to activate the card. This type of card may cause electrical shock or damage due to frequent contact of the contact, but it is highly used and is mainly used in a field that needs to execute a specific encryption algorithm in the card.

In addition, an electronic card popularized by the development of an RFID module together with an IC card is an RF card of a contactless type. The RF card is the same as the IC card and the memory device necessary for the information processing function, but communicates with the terminal (IFD) by means of radio frequency signals (electromagnetic induction). Power is supplied and no physical contact is required between the card and the reader.

In addition, as an electronic card that can be used together contact and contactless, hybrid and combination cards are attracting attention in terms of utilization, and their usage is gradually increasing.

Hybrid cards are characterized in that they cannot share their respective internal resources because physically contact and contactless cards exist in a single electronic card. Separate memory is used, two or more separate operating systems can be used, and since there is no COB damage, it can record a large amount of information along with features that can be used semi-permanently. can do.

Combi cards are chemically coupled cards that share parts that can be shared by contact / contactless cards in one electronic card, and have the effect of integrating heterogeneous applications through internal resource sharing. Information can be recorded, and high security features make it almost impossible to forge / false, and one card can be used in various fields.

Recently, by attaching more power supply and display to these e-cards, users can search the contents stored in the e-cards themselves, or generate and display passwords using MCUs with access control functions through RFID modules. It became.

The electronic card equipped with such a display is completed by fixing the IC chip and the display on a plastic substrate and thermocompressing a plurality of plastic substrates on which a space for mounting the IC chip and the display is formed.

However, when manufacturing an electronic circuit module having various sizes and thicknesses by using a conventional card assembly method of punching plastic substrates and applying heat, the process steps are increased, and the thickness of the cards is also increased, so that precise assembly is possible. The disadvantage is that it is impossible. If it is difficult to assemble precisely, there is a disadvantage that it deviates from the international standard, such as not satisfying the flexibility set by the international standard. In particular, heat of 150 ° C. or higher applied in the thermocompression process damages the display embedded in the card.

In addition, since the information received or stored by the electronic card is displayed through the display, it is disadvantageous in that it is not suitable for the elderly and the visually impaired who have poor vision.

Accordingly, the present invention provides a card-type receiving apparatus and a manufacturing method which can check information input / output through a card by vibrating, light or sound by including a flexible display as well as a vibration motor, a light emitting diode, or a film speaker in the card body. There is a purpose.

2 to 9 are process flowcharts of the card-type receiving apparatus according to the present invention.

First, the printing layer 110 having the rear reflection layer (not shown) is fixed on the placement plate 220 on which the alignment pin 210 is formed.

The back printing layer 110 according to the present invention may be a PET substrate of several tens of micro-thickness capable of bending and insulating. When the back printing layer 110 is fixed on the placement plate 220, the curable resin 120 is applied to a predetermined thickness. At this time, by adjusting the amount of the curable resin 120, it is preferable that the curable resin 120 does not flow over the dam 130 in the process of attaching the dam 130 in a later step.

When the curable resin 120 is applied, the dam 130 having a predetermined height and width is attached to the rear printing layer 110.

Next, the curable resin 120 is dropped into the dam 130 and then flattened. The curable resin is injected outside the area where the electronic device is located in the dam, and the cured resin 120 is cured in a later process to form the body of the card-type receiving device together with the dam 130.

At this time, since the film-type speaker 180-1 generates sound by vibration due to a certain degree of bending, it is preferable to drop the curable resin 120 except for a region in which the film-type speaker 180-1 is located. .

When the curable resin 120 is flattened to the dam height, the alignment pin 210 formed on the placement plate 220 is used to attach the top printing layer 200 to the upper portion of the dam.

According to the present invention, the upper printing layer 200 preferably uses a film formed of a polymer-based material that can bend, and the IC chip 190 is mounted after perforation in advance. In addition, it is preferable to form a plurality of sound holes 191 and holes 192 for light output from the light emitting diodes 180-3 so that sound can be emitted from the film type speaker 180-1.

In order to mount the IC chip 190 at the correct position on the flexible PCB 170, the upper surface printing layer 200 is formed with alignment holes corresponding to the alignment pins formed in the arrangement. In the process of covering the top printing layer 200, bubbles 250 are generated between the curable resins 120. In order to remove the air bubbles generated, the roller 260 is moved from one end of the upper surface printing layer 200 to the other end while pressing at a predetermined pressure. Then, the thermosetting resin 120 accumulated with the bubble 250 is discharged.

When the pressing process using the roller 260 is completed, the curable resin 120 is cured at a UV irradiation or a predetermined temperature. The cured resin 120 becomes a card-shaped body together with the dam 130 and cuts it to complete a plurality of card-type receivers.

In the flexible display 160 according to the present invention, it is preferable to use a flexible substrate having no damage even in the bending of the card-type receiving apparatus 100 and to use a liquid crystal cell micro liquid crystal cell LCD formed of micro sized cells.

When the card-type receiving device formed as described above receives information from the outside through an IC chip or an RFID module, the card-type receiving device converts the text into a character in the MCU and displays it on the flexible display. In addition, the MCU sends a signal to the light emitting diode or the film type speaker to output the light or sound to inform the user of the information received from the outside.

The manufacturing method of the micro liquid crystal cell according to the present invention is as follows.

First, transparent electrodes are deposited on the upper and lower substrates by sputtering. The upper and lower substrates use plastic substrates. Plastic may be deformed by heat. Therefore, by pre-heating the upper and lower substrates on which the transparent electrode is formed, it is possible to prevent the deformation of the substrate that can occur in a later step.

A patterned transparent electrode is formed by using a photolithography process on the entire surface where the transparent electrode is deposited. Next, the spacer is sprayed on the upper or lower substrate and the 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 then the encapsulant is cured by UV exposure or heat treatment to form a semi-LCD cell. Semi-LCD cells can be cut and formed into independent cells.

Next, a liquid crystal micropixel mixture, which is a mixture of a liquid crystal and a curable polymer, is injected into a semi-LCD cell or an independent cell.

The liquid crystal micropixel mixture according to the present invention is formed by mixing a curable polymer having a suitable viscosity and a liquid crystal, followed by stirring. 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 naturally while forming a boundary with the curable polymer surrounding the adjacent liquid crystal.

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. Controlling the concentration of the curable polymer is possible by temporarily applying heat or UV in the process of mixing the liquid crystal and the curable polymer.

The mixed liquid crystal micropixel mixture is injected into the cell. For more smooth injection, the micro pixel mixture may be heat-treated within the range of 25 ° C. to 75 ° C. and then injected into the cell.

When the independent cell interior is filled with liquid crystal micropixel mixture, the cells are sealed and the curable polymer is cured. A plurality of light sources may be provided around the cell for uniform curing during UV curing. UV or thermosetting polymers act as an alignment layer on the transparent electrode as the curing proceeds. 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 speaker according to the present invention may use paper or a piezoelectric film as the film type speaker 180-1. In the case of piezoelectric film, the surface is treated by mechanical, physical or chemical method before depositing the electrode.

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 surfaces of the piezoelectric film is a mixture of one or more of platinum, gold, silver, copper, chromium, nickel, aluminum, ITO, IGO, IZO, AGO, and sulfur compounds, and includes all other common conductive materials. can do. In addition, certain solutions and materials may be added and mixed to increase the adhesion of the conductive material.

 The film-type speaker unit has an even distribution of conductive material in the piezoelectric film, so that an electric signal is evenly transmitted to the front surface of the piezoelectric film when a current is applied, and the piezoelectric film vibrates finely by the evenly transmitted acoustic signal to generate sound. That is, the film-shaped speaker unit vibrates finely by the current evenly transmitted to the film-type speaker unit, thereby converting the electrical signal into sound.

Although the present invention has been shown and described with reference to the preferred embodiments as described above, it is not limited to the above embodiments and those skilled in the art without departing from the spirit of the present invention. Various changes and modifications will be possible.
