More specifically, the electronic paper and a control integrated-circuit (Thin Film) thin film (Thin film) battery to control them using a thin film like The present invention relates to a card having a moving picture and a flashing function which are packaged in a form.
기존의 TV, 휴대폰 등에 쓰이는 디스플레이는 액정 디스플레이(Liquid Crystal Display)가 대부분이었다. 액정 디스플레이의 특성은 두껍고, 유리를 이용하기 때문에 깨지기 쉬우며, 화면이 켜져 있는 동안 계속해서 전력이 소비되는 특성이 있다. 하지만 최근의 전자종이(E-paper) 디스플레이는 매우 얇고, 플라스틱 필름 등을 이용하여 깨지지 않고 휘어지는 특성이 있으며, 화면을 유지하는 데에 전력을 전혀 소비하지 않고 화면 전환 시에만 약간의 전력이 필요하기 때문에 차세대 디스플레이로 각광받고 있다. 또한 휘어지는 특성 때문에 제조 시에 롤투롤(Roll-to-roll) 공정이 가능해짐으로써 매우 저렴한 가격에 제조를 할 수 있 다는 특징이 있다. Most displays used in TVs, mobile phones, etc. were liquid crystal displays. The characteristics of liquid crystal displays are thick, fragile due to the use of glass, and consume power continuously while the screen is on. However, the recent E-paper display is very thin, has a characteristic of being unbreakable by using plastic film, etc., and does not consume any power to maintain the screen and requires only a little power when switching the screen. As a result, it is attracting attention as the next generation display. In addition, due to the bending property, the roll-to-roll process is possible at the time of manufacture, which makes it possible to manufacture at a very low price.
또한 배터리 기술 또한 최근 비약적으로 발전했으며 1mm미만의 두께를 갖는 박막형 배터리를 제조하는 것이 가능해졌고, 가격 또한 낮아지고 있다.In addition, battery technology has recently advanced dramatically, and it is possible to manufacture thin-film batteries having a thickness of less than 1 mm, and the price is also decreasing.
이에 본 발명의 목적은 위와 같이 얇고, 깨지거나 부러지지 않고 휘어지며 전력을 거의 소비하지 않는 전자종이 디스플레이를 이용한 카드 및 그 설계방법을 제공하는 데 있다.Accordingly, an object of the present invention is to provide a card using an electronic paper display that is thin, not broken or broken, and consumes little power as described above, and a design method thereof.
본 발명의 다른 목적은 위와 같은 전자종이 디스플레이를 이용하여 기존과 같이 정지된 형태의 정적인 카드가 아닌 움직이는 그림이나 점멸 기능 등이 가능한 동적인 카드 및 그 설계방법을 제공하는데 있다.It is another object of the present invention to provide a dynamic card and a design method thereof, which allow a moving picture or a flashing function, etc., rather than a static card of a stationary form as before, by using the electronic paper display as described above.
상기와 같은 목적을 달성하기 위한 본 발명은 전자종이 디스플레이 패널과; 전자종이 디스플레이 패널 뒷면에 부착된 박막형 배터리와; 디스플레이 패널을 컨트롤하기 위한 구동 집적회로; 내부에 연산처리용 CPU와; 임시 데이터 저장용 RAM과; 데이터 저장용 EEPROM 또는 플래시메모리와; 프로그램 코드 저장용 ROM 및 RF신호와 디지털 신호간 변환을 수행하는 RF모듈과; RF신호에서 구동용 전원을 생산하는 전원 생산부로 이루어진 일반적인 RF칩과; RF카드 단말기와 통신을 수행하는 RF안테나; 로 이루어짐을 특징으로 하는 카드를 제공한다. The present invention for achieving the above object is an electronic paper display panel; A thin film battery attached to the back of the electronic paper display panel; A driving integrated circuit for controlling the display panel; A CPU for arithmetic processing therein; RAM for temporary data storage; An EEPROM or flash memory for data storage; ROM for program code storage and RF module for converting between RF signal and digital signal; A general RF chip composed of a power generation unit for producing a driving power from an RF signal; An RF antenna for communicating with an RF card terminal; It provides a card characterized in that consisting of.
또한, 본 발명은 카드 제작을 위한 전자종이 디스플레이 패널을 더욱 저렴하게 하기 위하여 패시브 매트릭스(Passive matrix) 방식의 전자종이 디스플레이 패널을 사용하는 것을 특징으로 한다.In addition, the present invention is characterized by using an electronic paper display panel of the passive matrix (Passive matrix) method in order to make the electronic paper display panel for the card manufacturing more inexpensive.
혹은, 본 발명은 카드 제작을 위한 전자종이 디스플레이 패널의 화질을 더욱 높이기 위하여 액티브 매트릭스(Active matrix) 방식의 전자종이 디스플레이 패널을 사용하는 것을 특징으로 한다.Alternatively, the present invention is characterized by using an electronic matrix display panel of the active matrix (active matrix) method to further improve the image quality of the electronic paper display panel for the card manufacturing.
또한, 본 발명은 전자종이 디스플레이를 제어하기 위하여 적절하게 구동회로를 설계하여 이를 통해 움직이는 그림이나 점멸 기능을 구현하는 것을 특징으로 한다. In addition, the present invention is characterized by implementing a moving picture or flashing function by designing a drive circuit appropriately to control the electronic paper display.
또한 본 발명은 상기 구동회로를 설계할 시 배터리가 거의 다 소모되었을 경우 이를 발견하여 움직이는 그림 기능을 정지하고, 정지영상만을 내보냄과 동시에 남은 배터리를 이용하여 그림의 열화를 막기 위해 수개월에 한 번 정도 그림을 다시 불러오는 기능을 하는 것을 특징으로 하는 설계방법을 포함한다.In addition, the present invention, when designing the drive circuit, when the battery is almost exhausted, finds it and stops the moving picture function. Includes a design method characterized by the ability to recall pictures.
상술한 바와 같이 전자종이 디스플레이를 이용해 카드를 제작함으로써 움직이는 그림이나 점멸 기능 등 동적인 카드를 만들 수 있다. As described above, by making a card using an electronic paper display, a dynamic card such as a moving picture or a flashing function can be made.
이하 본 발명의 바람직한 실시 예를 첨부한 도면을 참조하여 설명한다. Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.
우선, 도 1을 참조하여 보면 스마트카드IC(4) 안에 CPU와 메모리가 있는데 드라이버IC(5)를 작동시킨다. 드라이버 IC(5)는 후면회로(2)를 통해서 전자종이 디스플레이(1)를 컨트롤한다. 이 모든 과정의 전력은 박막 배터리(3)에서 공급이 된다. 버튼(6)을 통해서 다양한 다른 기능들을 구현할 수 있다.First, referring to Figure 1 there is a CPU and a memory in the smart card IC (4) to operate the driver IC (5). The driver IC 5 controls the
구동 회로를 적절히 설계함에 따라 카드의 배경화면 및 글자를 움직이게 하여 움직이는 그림 기능의 카드를 제작할 수 있다. 구동 회로에는 비휘발성 메모리가 포함되어 있어 카드의 형태로 디스플레이 할 몇 개의 그림 파일을 저장하고 있고, 구동 회로 내의 연산장치(CPU)가 이들을 순차적으로 디스플레이 패널 구동 제어 신호로 바꾸고, 일정 주기로 쓰기 명령이 주어질 때마다 데이터 라인을 통하여 타이밍 신호에 맞추어 전자종이 패널의 각 화소에 보내지게 된다. 이를 통하여 움직이는 그림을 구현하게 된다.By properly designing the driving circuit, it is possible to make a card with a moving picture function by moving the background and text of the card. The driver circuit includes a nonvolatile memory, which stores several image files to be displayed in the form of a card, and the CPU in the driver circuit sequentially converts them into display panel drive control signals and write commands at regular intervals. Each time it is sent to each pixel of the electronic paper panel in accordance with the timing signal through the data line. This creates a moving picture.
도 2를 참조하여 보면, 전자종이 디스플레이 및 구동회로를 약간 다르게 설계함으로써 글자가 변하는 방식의 움직임도 가능하다. 상기와 마찬가지로 변하는 글자에 해당하는 그림 파일이 구동 회로 내에 저장되어 있다.Referring to Figure 2, by designing a slightly different electronic paper display and driving circuit it is possible to move the way the letters change. As described above, a picture file corresponding to the changing letter is stored in the driving circuit.
상술한 바와 같이, 본 발명은 전자종이 디스플레이 및 구동회로를 적절하게 배치, 설계함으로써 움직이거나 점멸하는 기능의 카드를 제공한다.As described above, the present invention provides a card having a function of moving or blinking by appropriately arranging and designing an electronic paper display and a driving circuit.
한편, 본 발명의 실시를 위한 구체적인 내용에서는 몇 가지 실시 예를 들어 설명하였으나, 본 발명의 범위에서 벗어나지 않는 한도 내에서 여러 가지 변형이 가능함은 물론이다. 그러므로 본 발명의 범위는 설명된 실시 예에 국한되어 정해져서는 안 되며 후설 하는 특허청구의 범위뿐 아니라 이 특허청구의 범위와 균등한 것들에 의해 정해져야 한다.On the other hand, the specific content for the practice of the present invention has been described with reference to some embodiments, of course, various modifications are possible without departing from the scope of the invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the claims to be described later, but also by the equivalents of the claims.
