도 2 및 도 3에 도시된 바와 같이, 지문 인식 영역인 인식부(110)는 화면(100)의 하단 등 사용자가 직관적으로 인지할 수 있는 부위에 일정 영역으로 구현된다. As illustrated in FIGS. 2 and 3, the recognition unit 110, which is a fingerprint recognition region, is implemented as a predetermined region on a portion that the user can intuitively recognize, such as the bottom of the screen 100.
본 발명의 실시예에 따르면, 이러한 영역 중 어느 부위에 사용자의 손가락이 터치되면, 인식부(110)는 지문을 인식하여, 인식된 지문이기인가된 사용자의 지문과 일치하는지 여부에 대한 인증을 수행하게 된다. According to an exemplary embodiment of the present invention, when a user's finger is touched in any part of the area, the recognition unit 110 recognizes a fingerprint and authenticates whether the recognized fingerprint matches the fingerprint of the authorized user.

키패드가 도 3과 같이 고정된 배열인 경우, 제3자는 사용자의 입력 양태를 엿본 후, 비밀번호 정보를 유추할 수 있어, 보안성이 약한 문제점이 발생할 수 있는 바, 본 발명의 실시예에 따른 제어부(200)는 키패드에 대한 배치 변경 신호와 함께 키패드에 대한 디스플레이 명령 신호를 전송한다. In the case where the keypad is a fixed arrangement as shown in FIG. 3, the third party may infer the password information after looking at the user's input mode, so that a weak security problem may occur. 200 transmits a display command signal for the keypad along with a batch change signal for the keypad.
즉, 지문인식 영역에 현출되는 키패드는 가변 키패드로써, 사용자는 미리 기억하고 있는 비밀 번호를 가변 키패드의 배열에 부합하게 입력시킴으로써, 지문 인식 및 비밀번호를 연동한 보안성을 제공받는 것이 가능하다. That is, the keypad appearing in the fingerprint recognition area is a variable keypad, and the user can input a password stored in advance in accordance with the arrangement of the variable keypad, thereby providing security associated with fingerprint recognition and password.
도 5a 및 도 5b는 본 발명의 실시예에 따른 투명 지문 인식 및 비밀번호를 연동한 이중 보안 장치의 감지 패턴을 나타내는 예시도이다. 5A and 5B are exemplary views illustrating a detection pattern of a dual security device in which transparent fingerprint recognition and a password are linked according to an embodiment of the present invention.
본 발명의 실시예에 따른 감지 패턴(300)은 투명 패널을 구성하는 커버 글래스의 배면에 배치되어, 발생되는 정전용량 값을 순차적으로 읽어 들이는 센서 구조이다. 감지 패턴(300)은 투명 박막으로, 종, 횡축 연결선 및 게이트 절연체가 투명하게 구성된 박막형 트랜지스터 회로로 구성되며, 유도된 정전 용량 변화값을 순차적으로 전달하는 것을 특징으로 한다. The sensing pattern 300 according to the exemplary embodiment of the present invention is disposed on the rear surface of the cover glass constituting the transparent panel, and sequentially reads the generated capacitance value. The sensing pattern 300 is a transparent thin film, and is composed of a thin film transistor circuit in which vertical, horizontal connecting lines, and gate insulators are transparent, and sequentially transmits an induced capacitance change value.
종래 기술에 따른 지문인식 터치 센서는 광학식 센서 및 비광학식 센서를 이용하는데, 광학식 방식의 경우 소형화가 불가능하여 현재는 비광학 방식에 대한 연구가 주로 진행되고 있으며, 특히 정전 용량식 지문인식 터치 센서에 대한 연구가 주를 이루고 있다. The fingerprint touch sensor according to the prior art uses an optical sensor and a non-optical sensor, and in the case of the optical method, it is impossible to miniaturize, and now, research on the non-optical method is mainly conducted, particularly in the capacitive fingerprint touch sensor. The main research is.
정전 용량식 지문인식 터치 센서는 센서 내부에 미세한 구조의 캐패시터를 다수 구성함으로써, 지문의 미세 굴곡으로 인한 정전 용량의 변화를 인식하는 방법을 채택하고 있는데, 소재 및 회로를 포함한 기술적 한계로 인하여 불투명하고 극소 정전용량 변화에 대한 탐지가 어려워 미세한 지문 인식이 어려운 실정이다. The capacitive fingerprint touch sensor adopts a method of recognizing a change in capacitance caused by fine bending of a fingerprint by constituting a large number of capacitors with a fine structure inside the sensor, which is opaque due to technical limitations including materials and circuits. It is difficult to detect minute fingerprints because it is difficult to detect microcapacitance changes.
본 발명에 따르면, 전술한 구조를 통하여 500 pppi이상의 고해상도 정전식 센서 모듈을 구현하는 것이 가능하며, 감지 면적 및 둘레를 증가시켜 신호 감도를 향상시킴으로써, 투명 재질의 특성상 높은 저항으로 인하여 발생되는 신호 딜레이에 관한 문제점, 증착의 어려움에 대한 문제점을 함께 해결하는 것이 가능하다. According to the present invention, it is possible to implement a high-resolution capacitive sensor module of 500 pppi or more through the above-described structure, and by increasing the detection area and circumference to improve the signal sensitivity, the signal delay caused by the high resistance due to the characteristics of the transparent material It is possible to solve the problem with respect to the problem of, the difficulty of deposition.
도 5a 및 도 5b는 본 발명의 실시예에 따른 투명 지문 인식 및 비밀번호를 연동한 이중 보안 장치의 감지 패턴을 나타내는 예시도로써, 감지 패턴(300)은 지문 굴곡보다 미세한 간격으로 기설정된 간격에 따라 설치되고, 주변의 감지 패턴과 커플링(300a, 300b)되어 감지 면적 및 감지 둘레가 확장되는 것을 특징으로 한다. 5A and 5B are exemplary diagrams illustrating a detection pattern of a dual security device in which a transparent fingerprint recognition and a password are linked according to an embodiment of the present invention, and the detection pattern 300 is set at a predetermined interval at a smaller interval than fingerprint bending. It is installed, and coupled with the sensing pattern of the peripheral (300a, 300b) is characterized in that the sensing area and the sensing circumference is extended.
즉, 도 5b에 도시한 바와 같이, 커플링을 통하여 감지 면적 및 둘레의 길이가 증가되므로, 신호 감도가 높아지는 효과가 있다. That is, as shown in FIG. 5B, since the sensing area and the length of the circumference are increased through the coupling, the signal sensitivity is increased.
다시 말하면, 감지 패턴의 면적은 미세 간격으로 설정된 x축, y축 선에 의하여, 그 면적 증가에 있어 한계가 있는 바, 감지 패턴의 커플링을 통하여 감지 면적 및 둘레를 증가시켜 높은 신호 감도로 정전 용량을 유도하는 것이 가능하다. In other words, the area of the sensing pattern is limited by the x-axis and y-axis lines set at fine intervals, and the area of the sensing pattern is limited. The sensing area and the circumference are increased through the coupling of the sensing pattern, and thus the electrostatic force is detected at high signal sensitivity. It is possible to derive the dose.
또한, 커플링(300a, 300b)된 감지 패턴에 연결된 1개의 y 축 선으로 각각의 패턴을 교차식으로 on/off제어하여, 제어부와 감지 패턴 사이를 연결하는 전체 연결 선의 수(x축, y축 선)를 절반으로 줄이는 효과가 있다.In addition, the number of connecting lines (x-axis, y) connected between the control unit and the sensing pattern by controlling each pattern on / off alternately with one y-axis line connected to the sensing patterns coupled to the coupling 300a and 300b. It has the effect of reducing the axis by half.
커플링된 감지패턴 300a 및 300b는 기설정된 방식에 따라 교차식으로 온/오프 되며, 기설정된 방식은 문턱(threshold) 전압값, 문턱(threshold) 주파수 값 등 다양한 방식으로 구현됨이 가능하다. The coupled sensing patterns 300a and 300b are alternately turned on / off according to a preset method, and the preset method may be implemented in various ways such as a threshold voltage value and a threshold frequency value.
본 발명의 추가적인 실시예에 따른 감지 패턴(300)은 지문 접촉 신호 감지에 민감하지 않은 패턴 내부가 식각된 형상인 것이 더욱 바람직하다. 이러한 식각된 형상의 감지 패턴으로부터, 높은 인식 패턴 충전율을 확보하는 것이 가능한 효과가 있다. More preferably, the sensing pattern 300 according to an exemplary embodiment of the present invention has an etched shape inside the pattern which is not sensitive to fingerprint touch signal sensing. From this etched shape sensing pattern, it is possible to secure a high recognition pattern filling rate.
이제까지 본 발명의 실시예들을 중심으로 살펴보았다. 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자는 본 발명이 본 발명의 본질적인 특성에서 벗어나지 않는 범위에서 변형된 형태로 구현될 수 있음을 이해할 수 있을 것이다. 그러므로 개시된 실시예들은 한정적인 관점이 아니라 설명적인 관점에서 고려되어야 한다. 본 발명의 범위는 전술한 설명이 아니라 특허청구범위에 나타나 있으며, 그와 동등한 범위 내에 있는 모든 차이점은 본 발명에 포함된 것으로 해석되어야 할 것이다.So far I looked at the center of the embodiments of the present invention. Those skilled in the art will appreciate that the present invention can be implemented in a modified form without departing from the essential features of the present invention. Therefore, the disclosed embodiments should be considered in descriptive sense only and not for purposes of limitation. The scope of the present invention is shown in the claims rather than the foregoing description, and all differences within the scope will be construed as being included in the present invention.
