Description

The electronic emission card using the LED thin film display module {The Emission Display RF Card by the use of the thin film LED module}

The present invention relates to an LED light emitting display module, which is an LED light emitting display module device material used inside an electronic card and RFID-TAG, and emits an electronic money chip (COB) and high brightness light required for the production of an electronic card. The purpose is to make an electronic card is a light emitting display by combining the LED light emitting display module. As a thin-film module, LCD is the most common and commercialized technology, but LCD is difficult to manufacture and requires a minimum thickness of thin film liquid crystal flickering. It is difficult to manufacture a miniaturized product because of poor operation and expensive price. In order to solve this problem, the LED light emitting display module is designed by applying only the basic technology of LCD light emission. Electronic cards include contact cards (ISO-7816 Contact IC Card) and contactless (ISO-14443 Type A / B Contactless Card or Remote Coupling Communication Card) Magnetic Card (MSR: Magnetic Stripe Read), RFID-Card, TAG (ISO- 15963,15693).

The present invention is embedded in LED light thin film display device in various forms of media such as electronic money card, transportation card, credit card, RF-ID card, RF-ID TAG based on electronic card. When the LED light emitting display module is built-in, the LDE emits light when the power is supplied from the radio frequency conversion coil antenna, and the light is collected through the reflecting angle reflector of the light emitting thin film module to emit light from the thin film display film. To integrate the module.

The smart card chip (Smart Card Chip), which is developed and manufactured and used in various countries at home and abroad, is equipped with an electronic card operating system (COS) based on a micro processor unit (MPU). It has its own computational functions, information storage functions (EEPROM, FRAM), secure encryption algorithms (DES, RAS, SEED, T-DES), and input / output data ports (I / O). Smart card chips are RISC-structured MPUs that are developed and used in 8-bit, 16-bit, and 32-bit forms. Since the smart card semiconductor chip mounted on the electronic card is equipped with an operating system and application software on a hardware basis, the usage information stored in the smart card can be utilized by an application program on a terminal or a computer that reads the electronic card. The developed electronic card is provided to system developers and developed into many applications, and is used in real life as the bank's credit card, transportation card, pass, membership card, etc., and also used in industrial fields. TAG) has been developed and applied to a wide range of fields.

As the electronic card is manufactured in the form of a card or a tag that can perform various functions in practical use, a light emitting display card or a tag must be modularized so that it can be easily made in the manufacturing process. Since the internal structure of the electronic card includes an antenna for driving the COB junction and the COB and communicating with the terminal, the LED light emitting display module is also manufactured so that the module does not exceed the minimum thickness of 0.46 mm. Electronic card and credit card manufacturing standards must be manufactured in compliance with the international ISO standard, so that the maximum thickness is within 0.76mm, the outer layer of the card, PVC (Polyvinyl Chloride) and PET-G (Glycol-) LED light emitting display module should be embedded in modified polyethylene terephthalate.

Semiconductors that make up electronic cards developed domestically and internationally, namely smart card chips, are classified into Native, Open Flat Form (Java), Multos, and WFSC according to the operating system.Contact and contactless according to data input / output methods. Can be classified in the form of Combi. Since the smart card chip of the contactless electronic card is driven by radio frequency, two junction terminals are connected to the antenna on the back of the COB to receive electromagnetic signals from the electronic card terminal and convert them into electrical signals required by the smart card. To drive. In addition, by converting the information performed in the smart card into an electromagnetic signal to communicate with the terminal to update the information in the smart card. Since the contact type electronic card is directly connected to the terminal and the smart card chip, information is exchanged and updated through necessary electrical signals and data communication through the connected terminal.

As such, contact cards, contactless electronic cards and electronic card-based financial cards (credit cards, electronic money cards), transportation cards, tags, etc. do not have a module to emit light. The present invention requires a key device constituting the LED light emitting display module that emits high brightness light in order to express a variety of graphics, characters, figures, pictures, trademarks, logos, etc. in a medium including such a variety of cards, LED A process of integrating a conversion coil antenna, a light emitting film, and a reflector of the condensing module irradiation angle part is required.

The smart card chip is combined with the antenna and included in the PVC formation in the card to be located at a specific place in the card. The antenna positioning during the card manufacturing process is made in consideration of the embossed print space for embossing the card serial number in accordance with the international standard ISO standard. By embedding the LED light emitting display module in the electronic card manufactured as described above, it is possible to make an electronic card or a tag that emits light with high brightness in a desired direction such as before, after and both sides of the electronic card. It is a technology that can be manufactured when manufacturing a card in various colors and patterns by processing graphics according to the shape to be represented as a light source emitted on the surface of the electronic card, and bonding work such as bond or air fox to fix the LED light emitting display module It is not necessary.

In general, an additional work process occurs because the LED light emitting display module, which was not previously required in the manufacture of an electronic card, is embedded in the card. However, the LED light emitting display module is embedded in the necessary place inside the card and has a high level of high precision. Can be built without requiring In addition, since the LED light emitting display module is a separately configured device, it adopts a structure that does not affect and interfere with the electronic card smart card and the terminal.
