Description

정전식 스타일러스Capacitive stylus
본 발명은 정전감응식 터치스크린의 입력 도구인 스타일러스에 관한 것으로서, 더욱 상세하게는 스타일러스의 감응부가 외부로 묻어나오지 않도록 하는 정전식 스타일러스에 관한 것이다.The present invention relates to a stylus which is an input tool of a capacitive touch screen, and more particularly, to a capacitive stylus which prevents the sensitive portion of the stylus from coming out.
현재 PDA(Personal Digital Assistant), 휴대 전화 단말기, 카 네비게이션 시스템(Car Navigation System), 타블릿(Tablet) PC 등 터치 입력 기능을 구비한 전자 제품은 폭 넓게 보급되고 있다. 이들 제품의 표시 스크린(Screen)은 감압식, 정전 감응식에 의해 감응한다. 정전식 터치스크린은 Indium Tin Oxide(In2O₃+SnO₂)이라는 전도성이 높은 유리로 구성되어 있다. 유리의 네 모서리에 센서가 부착됨으로 유리 표면에는 전류가 흐르는 상태가 된다. 이것을 통하여 전류의 변화를 인식하는 것이 정전식의 원리이다. Currently, electronic products having a touch input function such as a PDA (Personal Digital Assistant), a mobile phone terminal, a car navigation system, a tablet PC, and the like are widely used. The display screens of these products are sensitive by pressure sensitive or electrostatic sensitive. The capacitive touch screen is made of highly conductive glass called Indium Tin Oxide (In2O₃ + SnO₂). Sensors are attached to the four corners of the glass so that a current flows through the glass surface. It is the principle of the electrostatic that recognizes the change of current through this.
감응식 터치스크린에 손가락을 댄 순간에 유리에 흐르던 전자가 손가락을 통해 몸 안으로 흐르게 되어 이때 변화가 일어난 위치를 센서가 감지하여 동작하는 방식이다. 그러나 사용자마다 손가락의 크기가 달라 입력의 오류가 발생한다. The moment the finger touches the sensitive touch screen, the electrons that flowed on the glass flow into the body through the finger, and the sensor detects the position where the change occurred. However, different users have different finger sizes, which causes errors in input.
섬세한 터치를 위하여 정전식 스타일러스라는 도구를 사용한다. 종래의 정전식 스타일러스는 도 1과 같이 도전체로 이루어진 몸체부(1)와, 몸체부의 말단에 결합하는 감응부(2)로 이루어져 있다. 감응부(2)는 합성수지의 내부에 전도성 분말이 분산된 구조이며, 전기 전도성이다. 감응부(2)를 스크린에 마찰시킬 경우 전도성 분말 성분과 합성수지 성분이 떨어져 잔류물이 남게 된다. 이러한 잔류물은 손에 묻거나 기기의 내부에 들어가 고장을 일으킬 수 있게 된다.  For a delicate touch, a tool called the capacitive stylus is used. Conventional electrostatic stylus is composed of a body portion 1 made of a conductor as shown in Figure 1, and a sensitive portion (2) coupled to the end of the body portion. The sensitive part 2 has a structure in which conductive powder is dispersed in a synthetic resin and is electrically conductive. When the sensitive part 2 is rubbed on the screen, the conductive powder component and the synthetic resin component are separated to leave a residue. These residues can get on your hands or get inside the unit and cause malfunctions.
본 발명은 감응부가 스크린과 마찰을 일으키더라도 외부로 묻어나오지 않는 정전식 스타일러스를 제공하고자 한다.An object of the present invention is to provide an electrostatic stylus that does not come out to the outside even if the sensitive portion causes friction with the screen.

상기 감응부 표면에 코팅되며, 공극이 형성된 코팅부를 포함하되,Is coated on the surface of the sensitive portion, including a coating formed with voids,
상기 감응부가 상기 코팅부를 누르게 될 때, 상기 코팅부의 탄성력에 의해서 상기 공극이 열리면서 상기 감응부의 일부분이 감응식 터치스크린과 접촉하는 영역을 제공함으로써 상기 감응식 터치스크린의 전류가 상기 감응부를 통하여 상기 몸체부로 이동하는 것을 특징으로 하는 정전식 스타일러스가 제공된다.When the sensitive part is pressed against the coating part, the air gap is opened by the elastic force of the coating part, so that a part of the sensitive part is provided in contact with the sensitive touch screen so that a current of the sensitive touch screen is passed through the body. An electrostatic stylus is provided, characterized by moving negatively.
또한, 상기 코팅부는 폴리 우레탄, 우레탄 및 실리콘으로 이루어진 군으로부터 선택된 어느 하나일 수 있다.In addition, the coating unit may be any one selected from the group consisting of polyurethane, urethane, and silicone.
또한, 상기 코팅부의 두께는 0.01mm~1mm일 수 있다.In addition, the thickness of the coating portion may be 0.01mm ~ 1mm.
이상과 같이, 감응부에 공극이 형성된 코팅부를 결합시킴으로써, 스크린에 감응부를 밀착시키더라도 감응부의 잔류물이 스크린에 남지 않는다. 또한, 코팅부의 공극을 통하여 미세한 전류가 흐를 수 있어, 정전식 스타일러스는 원활하게 감응식 터치스크린을 작동시킬 수 있다.As mentioned above, by bonding the coating part in which a space | gap was formed in the sensitive part, even if the sensitive part is in close contact with the screen, no residue of the sensitive part remains on the screen. In addition, because a minute current can flow through the pores of the coating portion, the capacitive stylus can smoothly operate the sensitive touch screen.

이하에는, 본 발명의 바람직한 실시예를 첨부도면을 참조로 상세하게 설명하되, 이는 본 발명에 속하는 기술분야에서 통상의 지식을 가진 자가 본 발명을 용이하게 실시할 수 있을 정도로 상세하게 설명하기 위한 것이지, 이로써 본 발명의 사상 및 범주가 한정되는 것을 의미하지는 않는다.DETAILED DESCRIPTION Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, which are intended to explain in detail enough to enable those skilled in the art to easily carry out the present invention. This does not mean that the spirit and scope of the present invention is limited.
도 2는 본 발명의 일측면에 따른 정전식 스타일러스의 단면도이다. 본 실시예의 정전식 스타일러스(10)는, 전도성이 있는 몸체부(11)와; 상기 몸체부(11)의 말단에 결합하며, 합성수지(121)에 전도성 물질(122)이 분포되어 전도성이 있는 감응부(12)와; 상기 감응부(12) 표면에 커버되며, 상기 감응부(12)가 스크린에 누를 시 상기 스크린의 전류가 상기 감응부(12)를 통하여 상기 몸체부(11)로 이동할 수 있도록 공극(131)이 형성된 코팅부(13)를 포함한다.2 is a cross-sectional view of an electrostatic stylus according to one aspect of the present invention. Electrostatic stylus 10 of the present embodiment, the conductive body portion 11 and; It is coupled to the end of the body portion 11, the conductive material 122 is distributed in the synthetic resin 121, the sensitive portion 12 is conductive; The air gap 131 is covered on the surface of the sensitizer 12 so that the current of the screen can move to the body 11 through the sensitizer 12 when the sensitizer 12 is pressed on the screen. It includes a coating 13 formed.
정전식 스타일러스(10)는 감응식 터치스크린에 손가락 대용으로 사용하는 도구이다. 펜의 모양으로 생길 수도 있다. 본 실시예의 정전식 스타일러스(10)의 몸체부(11)를 손으로 잡고 감응식 터치스크린과 접촉할 경우, 감응식 터치스크린으로 흐르는 전류가 몸체부(11)를 따라 손으로 이동하게 되고, 이러한 전류의 흐름을 감응식 터치스크린이 인식하여 감응식 터치스크린을 구비한 전자기기가 작동한다.The capacitive stylus 10 is a tool used as a finger substitute for the sensitive touch screen. It can also look like a pen. When the body portion 11 of the capacitive stylus 10 of the present embodiment is held by hand and is in contact with the sensitive touch screen, the current flowing to the sensitive touch screen is moved by hand along the body portion 11. The sensitive touch screen recognizes the flow of electric current, and the electronic device with the sensitive touch screen operates.
몸체부(11)는 전도성 있는 물체이며, 비전도성 물질의 외부를 전도성 물질로 코팅하는 형태로 제조될 수 있다. 몸체부(11)는 금속재질로 만들어질 수 있다. Body portion 11 is a conductive object, it may be manufactured in the form of coating the outside of the non-conductive material with a conductive material. The body portion 11 may be made of a metal material.
몸체부(11)의 말단에는 감응부(12)가 결합한다. 감응부(12)는 합성수지(121)에 전도성 물질(122)이 분포된 형태이다. 감응부(12)는 몸체부(11)에 전류가 흐를 수 있도록 전기적으로 연결된다. 몸체부(11)가 직접 감응식 터치스크린에 닿을 경우 스크래치가 형성될 수 있어, 감응식 터치스크린을 손상시킬 수 있다. 따라서, 몸체부(11)의 말단에 부드럽고 신축성 있는 합성수지(121)를 포함하는 감응부(12)를 결합함으로써, 스크래치로 인한 문제를 해결하였다. At the end of the body portion 11, the sensitive portion 12 is coupled. The sensitive part 12 has a form in which the conductive material 122 is distributed in the synthetic resin 121. The sensitive portion 12 is electrically connected to the body portion 11 so that a current can flow. If the body portion 11 directly touches the sensitive touch screen, a scratch may be formed, which may damage the sensitive touch screen. Therefore, by combining the sensitive portion 12 including a soft and stretchable synthetic resin 121 at the end of the body portion 11, the problem due to scratch was solved.
합성수지(121)의 주재료로는 천연고무, 합성고무, 실리콘고무, 우레탄고무, 폴리우레탄 등일 수 있다. 전도성 물질(122)로는 카본, 금, 은, 구리, 니켈, 흑연 등일 수 있다. 전도성 물질(122)을 분말형태로 제조하여, 합성수지(121)에 분산시킬 수 있다. 전도성 물질(122)로 인하여 감응부(12)의 표면에서 몸체부(11)로 전류가 흐르게 된다. 따라서, 전도성 물질(122)은 합성수지(12)의 내외부에 상당히 밀도 있게 분포되어 있다.The main material of the synthetic resin 121 may be natural rubber, synthetic rubber, silicone rubber, urethane rubber, polyurethane, or the like. The conductive material 122 may be carbon, gold, silver, copper, nickel, graphite, or the like. The conductive material 122 may be prepared in powder form and dispersed in the synthetic resin 121. The conductive material 122 causes current to flow from the surface of the sensitive portion 12 to the body portion 11. Therefore, the conductive material 122 is fairly densely distributed in and out of the synthetic resin 12.
이러한, 전도성 물질(122) 뿐만 아니라, 전도성 물질(122)이 밀도 있게 분산됨으로 인하여 합성수지(121) 성분 간의 결합력이 약하다. 그 결과 약간의 마찰에도 외부로 잔류물이 남게 된다.Since the conductive material 122 as well as the conductive material 122 are densely dispersed, the bonding force between the components of the synthetic resin 121 is weak. As a result, residues remain externally with slight friction.
본 실시예는, 이러한 감응부(12)의 문제점을 해결하기 위하여, 감응부(12)에 코팅부(13)를 커버하였다. 코팅부(13)는 감응부(12)의 합성수지(121) 및 전도성 물질(122)이 외부로 묻어나오는 것을 방지한다. In this embodiment, in order to solve this problem of the sensitive portion 12, the coating portion 13 is covered with the sensitive portion 12. The coating part 13 prevents the synthetic resin 121 and the conductive material 122 of the sensitive part 12 from coming out.
코팅부(13)는 폴리우레탄, 우레탄, 실리콘으로 이루어진 군으로부터 선택된 어느 하나 일 수 있다. 또한, 다양한 합성수지를 선택할 수 있다. The coating part 13 may be any one selected from the group consisting of polyurethane, urethane, and silicon. In addition, various synthetic resins can be selected.
코팅부(13)의 두께는 0.01mm~1mm 정도로 얇은 것이 좋다. 코팅부(13)의 두께가 얇은 경우, 코팅부(13)를 형성하는 중에, 도 2와 같은 공극(131)이 자연스럽게 형성될 수 있다. 또한, 코팅부(13)의 두께가 얇을 경우 약간의 마찰이나 압력에 의해서 코팅부(13)가 찢어져 자연스럽게 공극(131)이 형성될 수 있다.The thickness of the coating part 13 may be as thin as about 0.01 mm to about 1 mm. When the thickness of the coating part 13 is thin, the gap 131 as shown in FIG. 2 may naturally be formed while the coating part 13 is formed. In addition, when the thickness of the coating part 13 is thin, the coating part 13 may be torn due to slight friction or pressure, and thus the void 131 may be naturally formed.
이러한 공극(131)은 전류가 흐를 수 있는 충분한 공간이 된다. 본 실시예의 정전식 스타일러스(10)를 감응식 터치스크린에 접촉시킬 경우, 도 3과 같이 감응부(12)가 코팅부(13)를 누르게 되고, 이때, 공극(131)이 열리면서 감응부(12)의 일부분이 감응식 터치스크린과 접촉하게 된다. 이러한 공극(131) 부분을 통하여 감응식 터치스크린의 전류가 몸체부(11)를 통하여 사람의 손으로 이동하게 된다.The gap 131 becomes a sufficient space for the current to flow. When the capacitive stylus 10 of the present embodiment is in contact with the sensitive touch screen, the sensitive part 12 presses the coating part 13 as shown in FIG. 3, and at this time, the air gap 131 is opened and the sensitive part 12 is opened. Is part of the contact with the sensitive touch screen. Through the air gap 131, the current of the sensitive touch screen is moved to the human hand through the body portion 11.
이러한, 공극(131)은 복수로 형성될 수 있으며, 감응부(12)의 전 영역에 분포 될 수 있다. Such a gap 131 may be formed in plural and may be distributed over the entire area of the sensitive portion 12.
이렇게, 전류가 흐를 수 있도록, 공극(131)이 형성된 코팅부(13)로 감응부(12)를 커버함으로써, 감응부(12)의 합성수지(121)와 전도성 물질(122)의 유출을 최소화시킬 수 있게 된다. In this way, by covering the sensitizer 12 with the coating 13 formed with the air gap 131 so that the current flows, the outflow of the synthetic resin 121 and the conductive material 122 of the sensitizer 12 can be minimized. It becomes possible.

Based on the present embodiment, modifications and additions made by those skilled in the art to the equivalent range will also belong to the scope of the present invention.
