Abstract

Provided is a single-layer touch screen panel in which the complexity in a wiring region including a plurality of touch pattern groups is improved.

Description

개선된 원 레이어 정전식 터치 패널Improved one layer capacitive touch panel
개선된 원 레이어 정전식 터치 패널에 관한 것으로서, 더욱 상세하게는, 배선 영역을 단순화한 원 레이어 정전식 터치 패널에 관한 것이다.An improved one layer capacitive touch panel, and more particularly, a one layer capacitive touch panel with a simplified wiring area.
터치 스크린 패널은 영상 표시 장치에 의해 표시된 내용에 기초하여 사람의 손 또는 다른 접촉 수단을 통해 사용자의 명령을 입력하는 장치이다. 이를 위하여 터치 스크린 패널은 영상 표시 장치의 전면(front face)에 구비되어 사람의 손 또는 다른 접촉 수단으로 직접 접촉된 접촉 위치를 전기적 신호로 변환한다. 이에 따라 접촉 위치에서 선택된 지시 내용이 입력 신호로 받아들여진다. The touch screen panel is a device for inputting a user's command through a human hand or other contact means based on the content displayed by the image display device. To this end, the touch screen panel is provided on the front face of the image display device to convert a contact position directly contacted by a human hand or other contact means into an electrical signal. Accordingly, the instruction selected at the contact position is received as an input signal.
터치 스크린 패널을 구현하는 방식으로는 저항막 방식, 광감지 방식 및 정전 용량 방식 등이 알려져 있다. 정전 용량 방식의 터치 패널은 사람의 손 또는 물체가 접촉될 때 도전성 감지 패턴이 주변의 다른 감지 패턴 또는 접지 전극 등과 형성하는 정전용량의 변화를 감지하고 접촉 위치를 전기적 신호로 변환한다. As a method of implementing a touch screen panel, a resistive film method, a light sensing method, and a capacitive method are known. The capacitive touch panel detects a change in capacitance formed by the conductive sensing pattern when the human hand or an object is touched by another sensing pattern or ground electrode, and converts the contact position into an electrical signal.
종래 기술에 따른 정전식 터치 스크린 패널은 횡방향의 선형 터치패드, 종방향의 선형 터치패드가 고가의 ITO층으로 형성되어 있어서, 이를 적용한 제품의 비용이 상승하게 되며, 기판을 사이에 두고 양면으로 각 터치패드를 형성하는 공정이 필요하므로 제조공정 또한 복잡하다.In the capacitive touch screen panel according to the prior art, the linear touch pad in the lateral direction and the linear touch pad in the longitudinal direction are formed of an expensive ITO layer, thereby increasing the cost of the product to which it is applied. Since the process of forming each touch pad is required, the manufacturing process is also complicated.
도 1은 종래 기술에 따른 정전식 터치 스크린 패널의 다른 예에 관한 평면 구성도이다.1 is a plan view illustrating another example of a capacitive touch screen panel according to the related art.
도 1에 도시한 바와 같이 정전식 터치 스크린 패널은 하나의 층에 제1터치패드(7a), 제2터치패드(7b)가 형성된다. 그러나, 제1터치패드(7a)는 종 방향으로 연결되어 있고, 제2터치패드(7b)는 횡방향으로 연결되어 있다. 도 1에 도시된 터치 스크린 패널은 단일 면(싱글 레이어)에 터치 패드(7a, 7b)를 형성하는 대신 배선 영역을 복수의 층으로 형성하는 특징을 갖는다.As shown in FIG. 1, the capacitive touch screen panel includes a first touch pad 7a and a second touch pad 7b in one layer. However, the first touch pad 7a is connected in the longitudinal direction, and the second touch pad 7b is connected in the lateral direction. The touch screen panel shown in FIG. 1 has a feature of forming wiring regions in a plurality of layers instead of forming touch pads 7a and 7b on a single surface (single layer).
따라서, 도 1에 도시된 터치 스크린 패널은 제1터치패드(7a) 및 제2터치패드(7b)와 손가락 사이에 형성되는 커패시턴스의 크기를 전하의 충전량, 방전량, 충전 시간, 또는 정해진 시간 내 구동 신호의 펄스 개수 등을 이용하여 검출함으로써, 접촉 위치의 제1축 방향 및 제2축 방향에 대한 위치를 추출하여 터치 지점을 인식할 수 있다.Accordingly, the touch screen panel illustrated in FIG. 1 may determine the magnitude of the capacitance formed between the first touch pad 7a and the second touch pad 7b and the finger within a charge amount, a discharge amount, a charge time, or a predetermined time. By detecting the pulse number of the driving signal, the touch point may be recognized by extracting the positions of the contact positions in the first and second axis directions.
도 1에서의 터치 스크린 패널은 단일 면에 터치 패드를 형성하여 터치 스크린 패널의 두께 감소를 도모할 수 있지만, 각 배선이 겹치는 영역이 발생하므로, 배선 간의 쇼트를 막기 위해 브릿지 또는 비아홀 등을 이용하여 배선 간을 점프하는 개수가 많아지는 문제점이 있었다. 이러한 배선 영역에서의 복잡한 구조때문에 터치 스크린 패널의 표시 영역이 단일 면으로 형성되더라도 터치 패널의 전체의 두께 증가, 테두리 폭 증가, 공정 복잡화에 의한 수율 감소의 문제가 발생한다.In the touch screen panel of FIG. 1, a touch pad may be formed on a single surface to reduce the thickness of the touch screen panel. However, since overlapping areas are formed in each touch screen, a bridge or via hole may be used to prevent short circuits between the wires. There has been a problem that the number of jumping between wirings increases. Due to such a complicated structure in the wiring area, even if the display area of the touch screen panel is formed as a single surface, problems of increase in thickness of the entire touch panel, increase in edge width, and decrease in yield due to process complexity occur.

이하에서는 첨부한 도면을 참조하여 본 발명을 설명하기로 한다. 그러나 본 발명은 여러 가지 상이한 형태로 구현될 수 있으며, 따라서 여기에서 설명하는 실시예로 한정되는 것은 아니다. Hereinafter, with reference to the accompanying drawings will be described the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.
도 2은 일 측면에 따른 정전식 터치 패널의 터치패턴그룹을 도시한 도면이다.2 illustrates a touch pattern group of a capacitive touch panel according to an exemplary embodiment.
도 2을 참조하면, 일 측면에 따른 정전식 터치 패널은 복수 개의 터치패턴그룹(100)을 포함할 수 있다.Referring to FIG. 2, the capacitive touch panel according to an aspect may include a plurality of touch pattern groups 100.
터치패턴그룹(100)은 표시 영역 내에 단일 면에 배치되는 복수 개의 터치패드(200)를 포함할 수 있다.The touch pattern group 100 may include a plurality of touch pads 200 disposed on a single surface in the display area.
이 때, 터치패드(200)는 터치 입력을 검출하기 위하여 기판 상에 패터닝 된 전극으로서 손가락이나 도전체와 같은 터치 입력 도구와의 사이에서 정전용량을 형성할 수 있다.In this case, the touch pad 200 may form capacitance between a touch input tool such as a finger or a conductor as an electrode patterned on a substrate to detect a touch input.
또한, 터치패드(200)는 투명 전도성 물질일 수 있다. 예를 들어, 터치패드(200)는 ITO(Indium Tin Oxide), ATO(Antimony Tin Oxide), CNT(Carbon Nano Tube), IZO(Indium Zinc Oxide) 등의 투명 전도성 물질일 수 있다. 그러나, 다른 예에서는 터치패드(200)가 금속 일 수 있다. 여기서, 터치패드(200)는 각각 독립 상태의 다각형으로 터치 스크린 전면에 걸쳐 복수 개가 배치될 수 있다. In addition, the touch pad 200 may be a transparent conductive material. For example, the touch pad 200 may be a transparent conductive material such as indium tin oxide (ITO), antimony tin oxide (ATO), carbon nano tube (CNT), and indium zinc oxide (IZO). However, in other examples, the touch pad 200 may be metal. Here, a plurality of touch pads 200 may be arranged in a polygonal state in an independent state over the entire touch screen.
정전식 터치 패널에서 Y축 방향으로 연결된 터치패드들 중 일부는 표시 영역 외부의 외곽 배선(A1, A2, A3, A4)에 의해 연결될 수 있고, 나머지는 표시 영역 내에서 제1 내부 배선(B1, B2, B3, B4)에 의해 연결될 수 있다. 또한, X축 방향으로 연결된 터치패드들 중 일부는 제1 내부 배선(B1, B2, B3, B4)과 겹치지 않는 제2 내부 배선(C1)에 의해 연결될 수 있다. Some of the touch pads connected in the Y-axis direction of the capacitive touch panel may be connected by outer wirings A1, A2, A3, and A4 outside the display area, and the others may be connected to the first internal wires B1, It may be connected by B2, B3, B4). In addition, some of the touch pads connected in the X-axis direction may be connected by second internal wires C1 that do not overlap the first internal wires B1, B2, B3, and B4.
상이한 터치패턴그룹에 속한 Y축 방향으로 연결된 터치패드는 외곽 배선(A1, A2, A3, A4)에 의해 연결될 수 있으며, 동일한 터치 패턴 그룹에 속한 Y축 방향으로 연결된 터치패드는 제1 내부 배선(B1, B2, B3, B4)에 의해 연결될 수 있다.Touch pads connected in the Y-axis direction belonging to different touch pattern groups may be connected by outer wirings A1, A2, A3, and A4. Touch pads connected in the Y-axis direction belonging to the same touch pattern group may be connected to the first internal wiring ( By B1, B2, B3, B4).
예를 들어, 동일한 터치패턴그룹(100) 내부의 Y축 방향으로 연결된 터치 패드들은 제1 내부 배선(B1, B2, B3, B4)에 의해 연결될 수 있다. 하지만, 상이한 터치패턴 그룹(도면 미표시)의 Y축 방향으로 연결된 터치 패드는 외곽 배선(A1, A2, A3, A4)에 의해 연결될 수 있다. 즉, 동일한 터치패턴그룹(100) 내부의 Y축 방향으로 연결된 터치 패드들은 제1 내부 배선(B1, B2, B3, B4)에 의해 연결되지만, 해당 터치패턴그룹(100) 외부에 배치된 터치패턴그룹(도면 미표시)의 터치 패드들과는 외곽 배선(A1, A2, A3, A4)에 의해 연결될 수 있다.For example, touch pads connected in the Y-axis direction inside the same touch pattern group 100 may be connected by first internal wires B1, B2, B3, and B4. However, touch pads connected in the Y-axis direction of different touch pattern groups (not shown) may be connected by outer wirings A1, A2, A3, and A4. That is, touch pads connected in the Y-axis direction inside the same touch pattern group 100 are connected by the first internal wires B1, B2, B3, and B4, but touch patterns disposed outside the corresponding touch pattern group 100 are provided. The touch pads of the group (not shown) may be connected by outer wirings A1, A2, A3, and A4.
제1 내부 배선(B1, B2, B3, B4) 및 제2 내부 배선(C1)은 동일 면에 배치될 수 있다. 여기서, 표시 영역은 터치 패널 상에서 터치를 인식하고 그에 따른 화면을 보여주는 영역을 나타내며, 예를 들어, 베젤을 제외하고 터치를 감지하기 위한 영역을 포함할 수 있다또한, 외곽 배선(A1, A2, A3, A4), 제1 내부 배선(B1, B2, B3, B4) 및 제2 내부 배선(C1)은 터치패드(200)와 동일한 재질일 수 있다. 예컨대, 터치패드(200)가 ITO 등과 같은 투명 전도성 물질인 경우, 외곽 배선(A1, A2, A3, A4), 제1 내부 배선(B1, B2, B3, B4) 및 제2 내부 배선(C1) 또한 동일한 재질일 수 있다. 한편, 터치 스크린의 외곽이 베젤에 의해 가려지는 경우, 외곽 배선(A1, A2, A3, A4)은 저항이 낮은 금속 물질로 이루어질 수 있다.The first internal wires B1, B2, B3, and B4 and the second internal wires C1 may be disposed on the same surface. Here, the display area represents an area for recognizing a touch on the touch panel and showing a screen according to the touch panel. For example, the display area may include an area for detecting a touch except for a bezel. Further, the outer wirings A1, A2, and A3 may be included. A4, the first internal wires B1, B2, B3, and B4 and the second internal wires C1 may be made of the same material as the touch pad 200. For example, when the touch pad 200 is made of a transparent conductive material such as ITO, the outer wirings A1, A2, A3, and A4, the first inner wirings B1, B2, B3, and B4 and the second inner wiring C1 may be used. It may also be the same material. Meanwhile, when the outside of the touch screen is covered by the bezel, the outside wirings A1, A2, A3, and A4 may be made of a metal material having low resistance.
터치패턴그룹에 포함된 터치패드들의 외곽 배선(A1, A2, A3, A4), 제1 내부 배선(B1, B2, B3, B4) 및 제2 내부 배선(C1)에 의한 연결 방식은 다양한 형태로 구현될 수 있다.Connection methods of the external wirings A1, A2, A3, and A4, the first internal wirings B1, B2, B3, and B4, and the second internal wirings C1 of the touch pads included in the touch pattern group may be in various forms. Can be implemented.
터치패드(200)는 외곽 배선(A1, A2, A3, A4), 제1 내부 배선(B1, B2, B3, B4) 및 제2 내부 배선(C1)에 의해 후술할 터치 감지부(도면 미표시)와 연결될 수 있다. The touch pad 200 is a touch sensing unit (not shown) to be described later by the outer wirings A1, A2, A3, and A4, the first internal wirings B1, B2, B3, and B4, and the second internal wirings C1. It can be connected with.
한편, 일 측면에 따른 정전식 터치 패널은 터치 감지부(도면 미표시)를 더 포함할 수 있다.Meanwhile, the capacitive touch panel according to one side may further include a touch sensing unit (not shown).
터치 감지부는 터치패드(200)에 대한 접촉에 의해 발생하는 정전용량의 변화를 통해 접촉을 감지할 수 있다. 예를 들어, X축으로 연결된 터치 패드에 순차적으로 구동 신호가 제공되고, Y축으로 연결된 터치 패드가 순차적으로 이 구동 신호를 인식하는 경우, 접촉에 의해 인식되는 구동 신호의 변화량을 이용하여 접촉 및 그 좌표를 감지할 수 있다. The touch sensor may detect the touch through a change in capacitance generated by the touch on the touch pad 200. For example, when a driving signal is sequentially provided to the touch pads connected by the X-axis, and the touch pads connected by the Y-axis are sequentially recognized by the touch pad, the touch and the touch signals are changed by using the amount of change of the driving signal recognized by the contact. The coordinates can be detected.
도 2에서 Y축 방향으로 연결된 터치패드들은 동일한 열에 배열된 터치패드와 제1 내부 배선(B1, B2, B3, B4)을 통해 연결될 수 있다. 또한, X축 방향으로 연결된 터치패드들은 제2 내부 배선(C1)에 의해 서로 연결될 수 있다. 이 때, 제1 내부 배선(B1, B2, B3, B4)과 제2 내부 배선(C1)은 겹치지 않으며 동일한 면에 배치될 수 있다.In FIG. 2, the touch pads connected in the Y-axis direction may be connected to the touch pads arranged in the same column through the first internal wires B1, B2, B3, and B4. In addition, the touch pads connected in the X-axis direction may be connected to each other by the second internal wire C1. In this case, the first internal wires B1, B2, B3, and B4 and the second internal wires C1 may be disposed on the same surface without overlapping.
즉, 도 2에 도시한 터치패턴그룹(100)은 종래와 유사하게 터치패드가 배열되어 있음에도 불구하고, 배선들이 겹치지 않는다는 것을 알 수 있다.That is, in the touch pattern group 100 illustrated in FIG. 2, although the touch pads are arranged similarly to the related art, it can be seen that the wirings do not overlap.
따라서, 상기 터치패턴그룹(100)과 같은 구성을 통해 배선간의 겹쳐짐이 현저히 감소될 수 있다. 이러한 배선 영역의 단순화를 통해 터치 패널의 두께의 감소 및 공정 수율의 향상을 도모할 수 있다.Therefore, the overlap between wires can be significantly reduced through the same configuration as the touch pattern group 100. By simplifying the wiring area, the thickness of the touch panel can be reduced and the process yield can be improved.
즉, 종래에는싱글 레이어 정전식 터치 패널에서는 동일한 면에 터치패드를 배치하는 경우라 하더라도, 터치패드에 연결된 배선이 겹치게 되어, 브릿지 또는 비아홀 등을 이용하여 배선 간의 쇼트를 막아야 하는 지점의 개수가 많았으나, 상기 일 측면에 따른 정전식 터치 패널은 터치패턴그룹 내의 터치 패드들의 배선이 서로 겹치지 않기 때문에, 종래와 달리 배선 간의 쇼트를 막기 위해 브릿지 또는 비아홀 등을 형성할 필요가 없다. 따라서, 일 측면에 따라 복수의 터치패턴그룹으로 터치 스크린 패널을 구현하는 경우에는 배선 간의 점프해야 하는 지점의 개수가 대폭 감소된다.That is, in the conventional single layer capacitive touch panel, even when the touch pad is disposed on the same surface, the wires connected to the touch pad are overlapped, and thus the number of points to prevent the short circuit between the wires using a bridge or via hole is large. However, in the capacitive touch panel according to the above aspect, since the wirings of the touch pads in the touch pattern group do not overlap each other, there is no need to form bridges or via holes, etc., in order to prevent shorts between the wirings. Therefore, when implementing the touch screen panel with a plurality of touch pattern groups according to one aspect, the number of points to be jumped between the wirings is greatly reduced.
도 2에서 터치 패드와 배선 사이의 공간이 매우 크게 도시되어 있지만, 이것은 발명의 이해를 쉽게 하기 위해 과장되게 도시된 것이다. 실제 터치패드와 배선은 상당히 조밀하게 배치되어 터치 스크린의 표시 영역의 대부분을 차지한다. Although the space between the touch pad and the wiring is very large in FIG. 2, this is exaggerated for ease of understanding of the invention. In practice, the touchpad and the wiring are fairly dense and occupy most of the display area of the touch screen.
또한, 각각의 배선들은 터치패드의 모서리에 연결되어 불필요한 공간이 최소화 될 수 있다. 이와 같은 원리는 도 3 내지 도 6에도 동일하게 적용될 수 있다.In addition, each wire is connected to the edge of the touch pad can be minimized unnecessary space. This principle can be equally applied to FIGS. 3 to 6.
도 3는 또 다른 실시예에 의한 정전식 터치 패널의 터치패턴그룹을 도시한다.3 illustrates a touch pattern group of a capacitive touch panel according to another embodiment.
상기 정전식 터치 패널에 포함되는 터치패턴그룹(100)은 복수 개의 터치패드(200)를 포함할 수 있다. 예컨대, 터치패턴그룹(100)은 동일한 면에 배치되는 터치패드(200)를 포함할 수 있다. The touch pattern group 100 included in the capacitive touch panel may include a plurality of touch pads 200. For example, the touch pattern group 100 may include a touch pad 200 disposed on the same surface.
여기서, 터치패드(200)는 투명 전도성 물질일 수 있다. 예를 들어, 터치패드(200)는 ITO(Indium Tin Oxide), ATO(Antimony Tin Oxide), CNT(Carbon Nano Tube), IZO(Indium Zinc Oxide) 등의 투명 전도성 물질일 수 있다.Here, the touch pad 200 may be a transparent conductive material. For example, the touch pad 200 may be a transparent conductive material such as indium tin oxide (ITO), antimony tin oxide (ATO), carbon nano tube (CNT), and indium zinc oxide (IZO).
도 3의 또 다른 실시예에 따른 정전식 터치 패널의 터치패턴그룹은 도 2과 비교하여 행 및 열이 변경되었을 뿐이며, 연결되는 방식은 도 2과 동일하다. 즉, 도 3에 도시한 터치패턴그룹은 도 2에 도시한 터치패턴그룹을 90도 회전시킨 것과 유사한 구성이다.In the touch pattern group of the capacitive touch panel according to another exemplary embodiment of FIG. 3, only rows and columns are changed as compared to FIG. 2, and the connection method is the same as that of FIG. 2. That is, the touch pattern group shown in FIG. 3 has a configuration similar to that of rotating the touch pattern group shown in FIG. 2 by 90 degrees.
이와 같이, 도 3에 도시한 터치패턴그룹은 도 2에 도시한 터치패턴그룹과 동일한 원리를 공유하며, 이하 생략된 내용이라고 하더라도 도 2에 관한 내용은 도 3 에도 적용된다.As described above, the touch pattern group shown in FIG. 3 shares the same principle as the touch pattern group shown in FIG. 2, and the description of FIG. 2 applies to FIG.
도 4은 본 발명의 또 다른 실시예에 의한 정전식 터치 패널의 터치패턴그룹을 도시한 도면이다.4 illustrates a touch pattern group of a capacitive touch panel according to another embodiment of the present invention.
상기 정전식 터치 패널의 터치패턴그룹은 도 4에 도시한 바와 같이, 4x4의 매트릭스 형태로 배열되며, 동일한 면에 배치되는 터치패드(200)를 포함할 수 있다. 이 때, 터치패드(200)는 투명 전도성 물질일 수 있다. 예를 들어, 터치패드(200)는 ITO(Indium Tin Oxide), ATO(Antimony Tin Oxide), CNT(Carbon Nano Tube), IZO(Indium Zinc Oxide) 등의 투명 전도성 물질일 수 있다.As illustrated in FIG. 4, the touch pattern group of the capacitive touch panel may include a touch pad 200 arranged in a 4 × 4 matrix and disposed on the same surface. In this case, the touch pad 200 may be a transparent conductive material. For example, the touch pad 200 may be a transparent conductive material such as indium tin oxide (ITO), antimony tin oxide (ATO), carbon nano tube (CNT), or indium zinc oxide (IZO).
상기 정전식 터치패널의 터치패턴그룹은 도 2에 도시한 터치패턴그룹과 유사하게 배열된 터치패드들과 그 하측에 X축 방향으로 연결된 터치패드들이 추가된 구성이다. 즉, 도 2과 유사하게 터치패턴그룹에서의 Y축 방향으로 연결된 터치패드들 및 X축 방향으로 연결된 터치패드들이 각 배선들과 연결되고, X축 방향으로 연결된 터치패드들 중 일부가 제2 내부 배선(C2)에 의해 연결되며 제1 내부 배선(B1, B2, B3, B4)과 겹치지 않도록 구성된다. 제2 내부 배선(C2)에 의해 연결되는 X축 방향의 터치패드들은 배선으로 연결되지 않고, X축 방향의 막대 형태로 구현되어도 무방하다. The touch pattern group of the capacitive touch panel has a configuration in which touch pads arranged similarly to the touch pattern group shown in FIG. 2 and touch pads connected in the X-axis direction are added below. That is, similar to FIG. 2, the touch pads connected in the Y-axis direction and the touch pads connected in the X-axis direction in the touch pattern group are connected to the respective wires, and some of the touch pads connected in the X-axis direction are second inside. It is connected by the wiring C2 and is configured not to overlap with the first internal wirings B1, B2, B3, and B4. The touch pads in the X-axis direction connected by the second internal wires C2 may not be connected by wires, but may be implemented in the form of bars in the X-axis direction.
도 4에 도시한 터치패턴그룹은 도 2에 도시한 터치패턴그룹과 동일한 원리를 공유하며, 이하 생략된 내용이라고 하더라도 도 2에 관한 내용은 도 4 에도 적용된다.The touch pattern group shown in FIG. 4 shares the same principle as the touch pattern group shown in FIG. 2, and the description about FIG. 2 applies to FIG.
도 5는 본 발명의 또 다른 실시예에 의한 정전식 터치 패널의 터치패턴그룹을 도시한 도면이다.5 is a diagram illustrating a touch pattern group of a capacitive touch panel according to another exemplary embodiment of the present invention.
상기 정전식 터치 패널의 터치패턴그룹은 도 5에 도시한 바와 같이, 동일한 면에 배치되는 터치패드(200)를 포함할 수 있다.The touch pattern group of the capacitive touch panel may include a touch pad 200 disposed on the same surface as shown in FIG. 5.
도 5에 도시한 터치패턴그룹은 도 2에 도시한 터치패턴그룹의 확장된 형태로, Y축 방향으로 연결된 터치패드들 중 일부는 표시 영역 외부의 외곽 배선(A1, A2, A3, A4, A5, A6, A7, A8)에 의해 연결될 수 있고, 나머지는 표시 영역 내에서 제1 내부 배선(B1, B2, B3, B4, B5, B6, B7, B8)에 의해 연결될 수 있다. 또한, 도 5에 도시한 터치패턴그룹의 X축 방향으로 연결된 터치패드들의 일부는 제1 내부 배선(B1, B2, B3, B4, B5, B6, B7, B8)과 겹치지 않는 제2 내부 배선(C1)에 의해 연결될 수 있다. The touch pattern group illustrated in FIG. 5 is an extended form of the touch pattern group illustrated in FIG. 2, and some of the touch pads connected in the Y-axis direction include outer wirings A1, A2, A3, A4, and A5 outside the display area. , A6, A7, and A8, and the rest may be connected by the first internal wirings B1, B2, B3, B4, B5, B6, B7, and B8 within the display area.

By C1).
이 때, Y축 방향과 X축 방향은 서로 직교하며, 제1 내부 배선(B1, B2, B3, B4, B5, B6, B7, B8) 및 제2 내부 배선(C1)은 동일 면에 배치될 수 있다. 또한, 제1 내부 배선(B1, B2, B3, B4, B5, B6, B7, B8) 및 제2 내부 배선(C1)은 터치패드(200)와 동일한 재질일 수 있다.At this time, the Y-axis direction and the X-axis direction are orthogonal to each other, and the first internal wirings B1, B2, B3, B4, B5, B6, B7, and B8 and the second internal wirings C1 may be disposed on the same plane. Can be. In addition, the first internal wires B1, B2, B3, B4, B5, B6, B7, and B8 and the second internal wires C1 may be made of the same material as the touch pad 200.

The touch pad may be connected in the Y-axis direction and may be connected by the outer wiring A1. Similarly, the touch pads arranged in the first row and the second column connected in the Y-axis direction and the touch pads arranged in the fifth row and the second column may be connected by the outer wiring A2.

Similarly, the touch pads arranged in the first row of the fifth row connected to the Y-axis direction belonging to the same touch pattern group and the touch pads arranged in the first row of the seventh row may be connected by the first internal wiring B1 ′.
한편, 도 6에 도시한 터치패턴그룹은 X축 방향으로 연결된 터치패드들 중 일부는 제1 내부 배선(B1, B2, B3, B4, B1', B2', B3', B4')과 겹치지 않는 제2 내부 배선(C1, C2, C3, C4)에 의해 연결된다.Meanwhile, in the touch pattern group illustrated in FIG. 6, some of the touch pads connected in the X-axis direction do not overlap the first internal wires B1, B2, B3, B4, B1 ′, B2 ′, B3 ′, and B4 ′. It is connected by the second internal wirings C1, C2, C3, and C4.
이 때, 제1 내부 배선(B1, B2, B3, B4, B1', B2', B3', B4') 및 제2 내부 배선(C1, C2, C3, C4)은 동일 면에 배치될 수 있다. 또한, 제1 내부 배선(B1, B2, B3, B4, B1', B2', B3', B4') 및 제2 내부 배선(C1, C2, C3, C4)은 터치패드(200)와 동일한 재질일 수 있다.In this case, the first internal wires B1, B2, B3, B4, B1 ′, B2 ′, B3 ′, and B4 ′ and the second internal wires C1, C2, C3, and C4 may be disposed on the same surface. . In addition, the first internal wires B1, B2, B3, B4, B1 ′, B2 ′, B3 ′, B4 ′ and the second internal wires C1, C2, C3, and C4 are made of the same material as the touch pad 200. Can be.
도 4의 확장 형태인 도 6의 터치패턴그룹은 배선이 겹치는 영역이 발생하지만, 종래보다 훨씬 적게 배선이 겹치게 된다는 것을 알 수 있다. 따라서, 종래 기술에 의한 터치 패널보다 배선 간의 점프해야 하는 개수가 적게 필요하다.In the touch pattern group of FIG. 6, which is an enlarged form of FIG. 4, an overlapping area is generated, but it can be seen that the wiring overlaps much less than before. Therefore, the number of jumps between wirings is less than that of the touch panel according to the prior art.
