Description

스타일러스 펜의 기울기 정보를 이용하는 디지타이저 장치Digitizer Device Using Tilt Information of Stylus Pen
본 발명은 디스플레이 기기에 사용되는 입력 장치인 디지타이저 장치에 관한 것으로, 보다 상세하게는 스타일러스 펜의 기울기 정보를 이용하는 디지타이저 장치에 관한 것이다. The present invention relates to a digitizer device, which is an input device used for a display device, and more particularly, to a digitizer device using tilt information of a stylus pen.
디지타이저(Digitizer)는 디스플레이 기기에 사용되는 입력 장치의 한 종류로서, 매트릭스 형태의 전극 구조를 포함하고, 사용자가 펜 또는 커서를 움직이면 매트릭스 상의 X, Y 좌표를 읽어 입력 장치의 위치 신호를 전달하고, 그에 해당되는 명령을 수행하는 장치이다. Digitizer is a type of input device used in display devices, and includes an electrode structure in the form of a matrix, and when a user moves a pen or a cursor, the digitizer reads the X and Y coordinates on the matrix and transmits a position signal of the input device. It is a device that performs the corresponding command.
디지타이저는 광의적으로 터치패널 또는 태블릿이라고도 불리며, 투명전극 층이 코팅되어 있는 두 장의 기판을 Dot Spacer를 사이에 두고 상호 마주보도록 합착시켜, 손가락이나 펜에 의해 상부 기판을 접촉할 시 위치 검출을 위한 신호가 인가되는 저항막 방식과, 표면파 발생의 트랜스듀서를 응용한 압전소자를 이용하는 초음파 반사 방식, 전자기파를 발생하는 패턴층 위에서 전자기파를 공명 흡수하는 코일을 이용하는 전자기공명 방식 및 사람의 몸에 있는 정전용량을 이용하여 전류의 양이 변경된 부분을 인식하여 위치를 검출하는 정전 용량 방식 등에 따라 구현된다. The digitizer is also widely called a touch panel or tablet, and two substrates coated with a transparent electrode layer are bonded to face each other with a Dot Spacer interposed therebetween to detect a position when the upper substrate is touched by a finger or a pen. A resistive film method to which a signal is applied, an ultrasonic reflection method using a piezoelectric element using a transducer for surface wave generation, an electromagnetic resonance method using a coil that resonancely absorbs electromagnetic waves on a pattern layer generating electromagnetic waves, and an electrostatic discharge in a human body It is implemented according to a capacitive method that detects a position by recognizing a portion where the amount of current is changed by using the capacitance.

When the tip of 110 contacts the same point P1 on the touch screen 104, there is a limit of measuring only the same position information P1 regardless of the tilt.
실질적인 펜 터치감은 선의 진하기, 선의 굵기, 선의 결 등으로 나타나는데, 도 2에 도시한 바와 같이 종래 기술에 따른 EMR 방식의 디지타이저는 사용자가 펜(110)으로 선을 그은 경우, 펜팁의 필압(P1, P2)은 선의 굵기에 제한적으로 작용하나, 대부분 선의 진하기에 영향을 주게 된다. The actual pen touch feeling is represented by the thickness of the line, the thickness of the line, and the texture of the line. As shown in FIG. 2, the EMR digitizer according to the related art has a pen pressure (P1) of the pen tip when the user draws a line with the pen 110. , P2) has a limited effect on the thickness of the line, but mostly affects the thickening of the line.
종이 위에 연필 등을 이용하여 선을 그리는 경우, 연필을 세게 누르는 정도에 따라 선의 진하기가 조절되며, 선의 굵기는 연필을 눕히고 세우는 정도에 따라 달라짐을 알 수 있다. If you draw a line using a pencil or the like on the paper, the darkening of the line is adjusted according to the degree of pressing the pencil hard, the thickness of the line can be seen that depends on the degree of laying the pencil upright.
그러나, 도 2에 도시된 종래 기술에 따른 EMR 방식의 디지타이저는 펜팁의 필압(P1, P2)를 인식하여, 선 굵기를 조절하는 바, 실질적인 펜 터치감을 그대로 실현할 수 없다는 문제점이 있다. However, the EMR digitizer according to the related art shown in FIG. 2 recognizes pen pressures P1 and P2 of the pen tips and adjusts the line thickness, and thus there is a problem in that the actual pen touch feeling cannot be realized as it is.

According to the exemplary embodiment of the present invention, the inclination values measured by the plurality of sensors 106a, 106b, 106c, and 106d are synthesized to finally obtain a three-dimensional inclination value of the stylus pen.
스타일러스 펜(110)이 터치스크린(104) 화면과 이루는 각도는 도 4에 도시된 바와 같이, z축과 이루는 θ값과, x, y 평면상에서 어느 쪽으로 기울어졌는지를 나타내는 방위각(azimuth)인 φ값으로 표현되며, 도 5는 본 발명의 실시예에 따른 스타일러스 펜(110)이 기울여진 상태(펜이 오른쪽으로 기울여진 경우)를 나타내는 상면도이다. As shown in FIG. 4, the angle that the stylus pen 110 makes with the screen of the touch screen 104 is θ value formed with the z axis, and φ value which is an azimuth indicating which direction is inclined on the x and y planes. 5 is a top view illustrating a state in which the stylus pen 110 is tilted (when the pen is tilted to the right) according to an embodiment of the present invention.
도 4에 도시된 바와 같이, 본 발명의 실시예에 따른 센서(106)는 터치스크린(104)의 상면에 대하여 수직방향으로 직교하는 축(z축) 및 터치스크린(104)의 상면에 접촉되는 스타일러스 펜(110)의 팁을 지나고, 스타일러스 펜의 중심을 관통하는 가상의 선(L1)이 이루는 기울기 값 θ를 측정한다. As shown in FIG. 4, the sensor 106 according to an exemplary embodiment of the present invention contacts an axis (z-axis) perpendicular to the top surface of the touch screen 104 and an upper surface of the touch screen 104.

또한, 본 발명의 실시예에 따른 센서(106)는 터치스크린(104)을 포함하는 평면(x, y 평면)에 대한 스타일러스 펜(110)의 방위각 φ를 산출한다. In addition, the sensor 106 according to the embodiment of the present invention calculates an azimuth angle φ of the stylus pen 110 with respect to the plane (x, y plane) including the touch screen 104.
도 6은 본 발명의 실시예에 따른 스타일러스 펜의 이동 방향에 따른 선 굵기 상태를 나타내는 예시도이다. 6 is an exemplary view showing a line thickness state according to the moving direction of the stylus pen according to the embodiment of the present invention.
도 5에 도시한 오른쪽으로 기울여진 스타일러스 펜(110)을, 터치 스크린(104) 면에 닿는 펜팁을 기준으로 보면, 이를 도 6에 도시한 바와 같이 좌표 상에서 일정 길이를 가지는 단위 막대(112)로 표현할 수 있다. Referring to the pen tip touching the surface of the touch screen 104, the stylus pen 110 tilted to the right side shown in FIG. 5 is referred to as a unit bar 112 having a predetermined length in coordinates as shown in FIG. 6. I can express it.
즉, 도 5와 같이 스타일러스 펜(110)이 오른쪽으로 기울여진 경우, 단위 막대(112)는 좌표계 중심에서 오른쪽으로 형성된 막대가 되며, 도 6의 화살표는 스타일러스 펜의 진행 방향을 나타낸다. That is, when the stylus pen 110 is inclined to the right as shown in FIG. 5, the unit bar 112 becomes a bar formed from the center of the coordinate system to the right, and the arrow of FIG. 6 indicates the traveling direction of the stylus pen.
스타일러스 펜(110)이 터치 스크린(104) 상에 접촉된 상태로 이동함에 따라, 스타일러스 펜(110)에 의하여 입력되는 선은 오른쪽 방향으로 가는 경우(112b로 도시함) 가장 가늘게 형성되고, 상하 방향으로 이동하는 경우(112c로 도시함)에 가장 굵은 선을 형성하게 된다. As the stylus pen 110 moves in contact with the touch screen 104, the line input by the stylus pen 110 is formed to be the thinnest in the right direction (shown as 112b), and the vertical direction In case of moving to (shown as 112c), the thickest line is formed.
또한, 비스듬한 기울기로 이동하는 경우(112a로 도시함)에는, 기울어진 각도와 연동한 굵기로 그 선의 굵기가 형성된다. In addition, when moving at an oblique inclination (shown by 112a), the thickness of the line is formed by the thickness in conjunction with the inclination angle.
도 7은 본 발명의 실시예에 따른 스타일러스 펜의 이동 방향에 따른 선 굵기 연산을 나타내는 예시도로써, 이하에서는 도 7을 참조하여 선 굵기 연산 과정을 상세히 설명하기로 한다. 7 is an exemplary diagram illustrating a line thickness calculation according to a moving direction of a stylus pen according to an embodiment of the present invention. Hereinafter, the line thickness calculation process will be described in detail with reference to FIG. 7.
본 발명의 실시예에 따른 스타일러스 펜의 기울기 정보를 이용하는 디지타이저 장치는 터치스크린 면에 대한 스타일러스 펜의 기울기 정보를 산출하고, 이를 이용하여 선 굵기를 조절하는 디지타이저 장치에 관한 것이다. The digitizer device using the inclination information of the stylus pen according to the embodiment of the present invention relates to a digitizer device for calculating the inclination information of the stylus pen with respect to the touch screen surface and using the same to adjust the line thickness.
즉, 펜의 기울기 값 θ 및 기울어진 방위각 φ를 산출하고, θ를 이용하여 펜팁이 터치스크린(104)에 닿는 면적(112)을 모사하고, φ 값과 스타일러스 펜의 진행 방향을 이용하여 프로젝션한 값으로 선의 굵기를 계산하면, 스타일러스 펜의 기울기 정보를 이용하여 다양한 굵기(T)의 선을 구현하게 된다. That is, the tilt value θ and the tilted azimuth angle φ of the pen are calculated, and the area 112 where the pen tip touches the touch screen 104 is simulated using θ, and is projected using the value of φ and the traveling direction of the stylus pen. When the thickness of the line is calculated using the value, various thicknesses of T may be implemented using the tilt information of the stylus pen.
스타일러스 펜(110)이 기울여진 상태로 터치스크린(104)의 상면에 접촉되는 경우, 터치스크린(104) 상에 접촉된 펜 팁의 위치가 출력되고, 이를 통하여 펜 팁의 위치를 인식하는 것이 가능하다.When the stylus pen 110 is in contact with the top surface of the touch screen 104 in an inclined state, the position of the pen tip contacted on the touch screen 104 is output, and thus the position of the pen tip can be recognized. Do.
본 발명의 실시예에 따른 제어부(108)는 센서(106)가 측정한 기울기 값 θ 을 이용하여 터치 스크린(104)과 접촉되는 스타일러스 펜의 펜팁의 길이 정보(L)를 획득하고, 방위각 φ 및 스타일러스 펜의 진행 방향을 고려하여 선 굵기(T)를 조절한다. The control unit 108 according to an embodiment of the present invention obtains the length information L of the pen tip of the stylus pen contacting the touch screen 104 using the inclination value θ measured by the sensor 106, and the azimuth angle φ and Adjust the line thickness (T) by considering the direction of travel of the stylus pen.
이 때, 제어부(108)는 선 굵기(T)를 조절하고, 스타일러스 펜(110)의 이동에 따른 필적의 그라데이션 디스플레이에 대한 명령 신호를 전송하게 된다. At this time, the controller 108 adjusts the line thickness T and transmits a command signal for the gradation display of the handwriting according to the movement of the stylus pen 110.
즉, 터치스크린(104) 상에는 스타일러스 펜의 기울기 정보 및 진행 방향 정보에 따라, 상이한 선 굵기가 구현되며, 상이한 선에 대하여 그라데이션 정도가 각각 달라지게 된다. That is, on the touch screen 104, different line thicknesses are implemented according to the inclination information and the moving direction information of the stylus pen, and the degree of gradation is changed for different lines.
스타일러스 펜의 기울기 θ가 커질수록, 스타일러스 펜은 터치스크린에 가깝게 기울여지므로, 펜팁이 터치스크린에 닿는 길이(L)가 길어지게 된다. As the inclination θ of the stylus pen increases, the stylus pen is inclined closer to the touch screen, so that the length L of the pen tip touching the touch screen becomes longer.
이 때, 펜팁이 기울어진 상태로 터치스크린에 닿는 경우, 펜팁이 터치스크린에 닿는 길이 L은 응용 프로그램 상에서 펜의 종류에 따른 옵션 등으로 사용자의 선택 또는 지정이 가능하도록 구성된다. At this time, when the pen tip touches the touch screen in an inclined state, the length L of the pen tip touching the touch screen is configured to enable the user to select or designate an option according to the type of the pen in the application program.
도 7에 도시된 바와 같이, 스타일러스 펜이 터치스크린 상에서 오른쪽으로, 즉 방위각 φ가 0인 방향으로 진행되는 경우, 그 선 굵기 T0는 아래 [수식 1]과 같이 연산된다. As shown in FIG. 7, when the stylus pen proceeds to the right on the touch screen, that is, in the direction in which the azimuth angle φ is 0, the line thickness T0 is calculated as shown in Equation 1 below.
