1 is a plan view of a touch panel according to an embodiment of the present invention.

In this embodiment, the touch panel includes a substrate 100 divided into a valid region and a non-valid region, a first sensing electrode (not shown) extending in the first direction to at least a portion of the non- A second sensing electrode 220 disposed in the effective region and extending in a second direction to at least a portion of the ineffective region and sensing a touch input; First and second wirings (300) connected to the first and second sensing electrodes, and a connection portion connecting one end of the first and second wirings and one end of the first and second sensing electrodes, (310) does not overlap with extension lines extending in the first and second directions of the first and second sensing electrodes (200).

The substrate 100 is divided into an effective region and an ineffective region in a structure in which an electrode is formed. Typically, the sensing electrode 200 is formed in the effective area and the wiring 300 is formed in the non-effective area. The substrate may be formed of various materials and may be formed into various shapes. The substrate may be rigid or flexible. For example, the substrate may comprise glass or plastic. In detail, the substrate may include chemically reinforced / semi-tempered glass such as soda lime glass or aluminosilicate glass, or may include polyimide (PI), polyethylene terephthalate (PET), propylene glycol (PPG), polycarbonate (PC), or the like, or may include sapphire.

In addition, the substrate may comprise an optically isotropic film. For example, the substrate may include a cyclic olefin copolymer (COC), a cyclic olefin polymer (COP), a polycarbonate (PC), a light polymethyl methacrylate (PMMA), or the like.

Sapphire has excellent electrical properties such as dielectric constant and can dramatically increase the speed of touch reaction. It can easily realize spatial touch such as hovering and is applicable as a cover substrate because of its high surface strength. Here, hovering means a technique of recognizing coordinates even at a close distance slightly away from the display.

In addition, the substrate may be curved with a partially curved surface. That is, the substrate may be partially flat and partially curved with a curved surface. In detail, the end of the substrate may be curved with a curved surface or may have a surface including a random curvature, and may be bent or bent.

In addition, the substrate may be a flexible substrate having flexible characteristics.

In addition, the substrate may be a curved or bended substrate. That is, the touch window including the substrate may be formed to have a flexible, curved, or bent characteristic. Accordingly, the touch window according to the embodiment is easy to carry and can be changed into various designs.

The sensing electrode 200 is formed in the effective region of the substrate 100 to sense the touch input of the user. The first sensing electrode 210 may be divided into a first sensing electrode 210 and a second sensing electrode 220 in the x axis direction on the touch panel. Axis direction on the touch panel. In this case, the x-axis direction may be the first direction, and the y-axis direction may be the second direction. The first and second sensing electrodes 200 recognize a point at which capacitance changes on the touch panel by a user's touch and acquire information about the point of touch generation on the two-dimensional coordinates of the touch panel.

The sensing electrode 200 may include a transparent conductive material to allow electricity to flow without disturbing the transmission of light. For example, the sensing electrode 200 may include indium tin oxide, indium zinc oxide, and may include metal oxides such as copper oxide, tin oxide, zinc oxide, and titanium oxide. Or nanowires, photosensitive nanowire films, carbon nanotubes (CNTs), graphene, or conductive polymers. The material for forming the sensing electrode 200 may include various metals. For example, the sensing electrode 200 may be formed of one selected from the group consisting of Cr, Ni, Cu, Al, Ag, and Mo. Gold (Au), titanium (Ti), and alloys thereof. In addition, the above listed materials can be mixed and used.

The wiring 300 is formed in a non-effective area of the substrate 100 and serves as a medium for transmitting an electric signal sensed by the sensing electrode 200 to a driver IC of a touch panel. One end (310) of the wiring (300) of the present invention is connected to the first and second sensing electrodes (200) through a connection part (400). The first and second wirings are connected to the first and second sensing electrodes, respectively. 1 to 4, only the first wiring is shown for the sake of convenience. Here, the first and second expressions are for convenience, and should be considered to include all the wirings formed in the ineffective area connected to the sensing electrode. The wiring 300 may include a metal having excellent electrical conductivity. The wiring 300 may include the same material as the sensing electrode 200 described above.

The connection unit 400 is configured to electrically connect the first and second sensing electrodes 200 and the first and second wirings 300. The sensing electrode 200 formed in the effective area generates a touch input in the form of an electric signal and transmits the same through a wiring 300 to a signal processing structure such as a driver IC. The connecting portion 400 is a constitution for connecting to the connecting portion 400. [ However, the connection part 400 is not necessarily physically separated from the sensing electrode 200 and the wiring 300, and when the sensing electrode 200 is directly connected to the wiring 300 in an extended form, ).

The present invention is arranged such that one end 310 of the first and second wirings does not overlap with the extension line of the first and second sensing electrodes 200 in the first and second directions. This will be described in more detail with reference to FIG.

The conventional touch panel is disposed such that one end 310 of the wiring and the sensing electrode 200 are arranged in parallel to the position perpendicular to the formation direction of the wiring 300 (or the non-effective region formation direction). 1, the wiring 300 is formed so that one end 310 of the wiring overlaps with a line formed by extending the sensing electrode 200 in the first direction (indicated by a first direction in FIG. 1). As a result, the distance between the wiring 300 and the sensing electrode 200 can be minimized, and the length of the connection part 400 can be minimized.

However, in this case, the minimum width of the bezel is required to form the wiring 300 (in particular, one end 310 of the wiring) and the connecting portion 400, respectively. When a printing process, an exposure process, or the like is performed to form an electrode, a minimum tolerance for smoothly performing each process must be ensured. For this purpose, the bezel must have a clearance of at least the minimum tolerance of each process. Particularly, when the guard portion 500 is formed on the bezel, it is difficult to reduce the width of the bezel region to less than a certain size because it includes the minimum width for generating the guard portion 500 in addition to the minimum tolerance.

1, the one end 310 of the first and second wirings (the point where the sensing electrode 200 and the connection portion 400 are connected to each other) is disposed at a position displaced from the sensing electrode 200, More specifically, when the sensing electrode 200 and the wiring 300 are formed so as not to overlap the first and second sensing electrodes 200, the sensing electrode 200, the connection unit 400, The width of the bezel can be narrowed as compared with the case where the ends 310 of the wiring are arranged side by side. Since the minimum tolerances necessary to form the sensing electrodes 200, the connecting portions 400 and the ends 310 of the wiring lines arranged in parallel are added to each other in the prior art, the minimum tolerance of the sensing electrodes 200, The minimum tolerance obtained by adding the minimum tolerances of the connection portions is secured on the bezel. However, since the present invention disposes the one end 310 of the wiring and the sensing electrode 200 at positions not parallel to each other, The minimum tolerances of the electrodes 200 can overlap each other and the bezel width can be reduced accordingly.

Therefore, the touch panel manufactured according to the structure shown in FIG. 1 can reduce the width of the bezel, and as a result, the overall size of the touch device can be reduced, thereby achieving the object of the present invention.

In one embodiment of the present invention, a guard unit 500 may be further disposed between the first sensing electrode 200 and the first wiring 300.

The guard part 500 serves to prevent static electricity or ESD in the touch panel. Static electricity or ESD can be prevented from flowing into the touch panel by moving along the path of the guard part 500. [ One end of the guard portion 500 may be connected to the printed circuit board. In detail, the guard part 500 is drawn to the upper or lower end of the substrate 100, connected to the printed circuit board, and can emit static electricity and ESD in the touch panel as an electrical signal. As a result, signal interference can be prevented and the accuracy and reliability of the touch can be improved. The guard portion 500 may be formed using a conductive material, for example, Ag or the like.

The guard part 500 may be formed entirely along the boundary between the effective area and the ineffective area of the touch panel, and may be formed in a ring shape along the boundary when the touch panel is made of a square.

The guard portion 500 described above is disposed between the sensing electrode 200 and the wiring 300. More specifically, it can be formed at a position inside the non-effective region of the substrate 100, that is, at a position closer to the effective region than the wiring 300 in the non-effective region.

In one embodiment of the present invention, the guard portion 500 may have a concavo-convex shape. Each side of the touch panel may be formed in a line shape including a curvature instead of a straight line based on a rectangular touch panel. FIG. 1 shows a part of the touch panel. The guard part 500 may be recognized as linear unevenness, but may have a ring shape having irregularities on the entire touch panel. In a case where the guard part 500 has a concavo-convex shape, one end 310 of the wirings arranged alternately and the sensing electrode 200 can be formed in the irregular shape of the concave-convex shape. One end 310 of the first or second wiring is formed on one side of the concave and convex shape and the one end of the sensing electrode 200 is formed on the other side of the concave and convex shape so that the wiring end 310 and the sensing electrode 200 can be shifted from each other. As a result, it is possible to protect the guard portion 500 even in a state in which the guard portion 500 is disposed in an offset manner.

The present embodiment can also maintain the relative positional relationship between the sensing electrode 200 and the wiring end 310 for reducing the bezel, thereby achieving the object of the present invention to reduce the width of the bezel.

In another embodiment of the present invention, the shapes of the connecting portions 400 may be different from each other. In this embodiment, the connection part 400 may have a point where at least one point is bent. This embodiment will be described with reference to FIG. 1 and FIG. FIG. 1 is a cross-sectional view of a touch panel according to an embodiment of the present invention, and FIG. 2 is a plan view of a touch panel according to an embodiment of the present invention.

Referring to FIG. 1, the connection portion 400 is formed in a 90 degree bent linear shape. Which may be bent according to one embodiment of the present invention between the wiring end 310 and the sensing electrode 200. 2, it can be seen that the connection part 400 is bent at the boundary between the valid area and the non-valid area. In this embodiment of the present invention, the bent portion may be formed so as to exist at the boundary between the valid region and the non-valid region. In other words, in the embodiment shown in FIGS. 1 and 2, it can be seen that the connecting part 400 has a bent shape at two points in total. However, in the example of FIG. 1, the wire 310 and the sensing electrode 200 may be connected to each other by a straight connection part 400, and in the example of FIG. 2, the wiring 300 and the sensing electrode 200, Can be formed on the same layer without the color print layer, so that the number of bending points of the connection portion 400 can be reduced. In this embodiment, at least one bent point is provided to efficiently connect the one end 310 of the wirings arranged to be shifted and the sensing electrode 200, but also the connection portion 400 to be described later The process can be simplified.

The bent point may be formed not only in the angular shape shown in FIG. 1 but also in the arc shape. That is, if the one end 310 of the wire is connected to the sensing electrode 200, the bent shape is not limited to the rectangular shape shown in FIG.

In an embodiment of the present invention, the connection part 400 may be formed by extending the sensing electrode 200. Since the connection part 400 can be formed through the process of forming the sensing electrode 200 using the same material as that of the sensing electrode 200, the manufacturing process of the touch panel can be simplified. As a result, the manufacturing cost can be reduced, and the process error can be reduced by reducing the process.

Meanwhile, in one embodiment of the present invention, the connection pad 400 may further include a connection pad 600 between one end 310 of the first and second wirings. The connection pad 600 enhances durability of the touch panel and is configured to prevent cracks from being generated or damaged due to an impact applied to the connection portion 400, the connection portion, and the like in the process of manufacturing the touch panel.

The impact transmitted to the connection portion 400 through the connection pad 600 can be mitigated. The connection pad 600 may be formed simultaneously in the process of forming the sensing electrode 200. That is, the connection pad 600 may be formed by extending the sensing electrode 200, as in the case of forming the connecting portion 400 by extending the sensing electrode 200 in the previous embodiment. At this time, the connection unit 400 is formed by extending any one of the first sensing electrode 210 and the second sensing electrode 200. Conversely, the connection pad 600 is connected to the first sensing electrode 210 or the second sensing electrode 200, The sensing electrode 200 may be formed to extend from the electrode 220 without forming the connection portion 400. The connection pad 600 can be formed using the second sensing electrode 220 if the first sensing electrode 210 is extended to form the connection portion 400. In contrast, If the connection unit 400 is formed, the first sensing electrode 210 may be extended to form the connection pad 600. Thus, the connection pad 600 can be formed together in the process of forming the sensing electrode 200, even if the process for forming the connection pad 600 is not performed separately.

Another embodiment of the present invention further includes an insulating layer 700 formed between the connection part 400 and the first and second wirings 300 in a region except for one end 310 of the first and second wirings. The insulating layer 700 not only insulates the various constituent (e.g., color print layer) formed on the ineffective area of the substrate 100, the wiring 300 and the guard portion 500, but also insulates the connection portion 400, (500), and the connection part (400) and the wiring (300). Since the wiring 300 and the connection unit 400 match each other in a one-to-one relationship, the connection unit 400 and the wiring 300 may be formed on the non- A wiring 300 that is not matched with the connection portion 400, that is, a wiring 300 that is not connected to the connection portion 400, is insulated.

4 is a plan view of a touch panel according to another embodiment of the present invention. In this embodiment, the touch panel includes a substrate 100 divided into a valid region and a non-valid region, a first sensing electrode (not shown) extending in the first direction to at least a portion of the non- A second sensing electrode 210 disposed in the effective region and extending in a second direction to at least a portion of the non-effective region and sensing a touch input, a second sensing electrode 210 formed in the non-effective region of the substrate 100 First and second wirings 300 connected to the first and second sensing electrodes 200 and a guard unit 500 disposed between the first sensing electrode 200 and the first wirings 300, The guard portion 500 includes a first portion 510 extending in the second direction, a second portion bent from the first portion 510 in the first direction and extending toward the effective region side from the ineffective region side 520), from the second portion (520) in the second direction Gokdoen from the third region 530 and the third region 530 extends in the first direction and a fourth portion (540) extending toward the non-effective areas in effective area side.

The description of the substrate 100 and the wirings 300 of the first and second sensing electrodes 200 has been described above and is not described in duplicate.

In this embodiment, the guard portion 500 includes the first portion 510 to the fourth portion 540. The guard portion 500 of the present invention may be formed such that the first portion 510 to the fourth portion 540 are repeatedly formed in the ineffective region of the substrate 100 along the outline of the effective region of the substrate 100. Hereinafter, various embodiments according to the shapes of the first to fourth parts 540 and the positions with respect to the wiring 300 will be described.

In one embodiment of the present invention, one end of the first wiring 300 and the third portion 530 may be disposed on the first direction extension line of the sensing electrode 200. In FIG. 4, a third portion 530 is formed between the plurality of sensing electrodes 200. The third portion 530 is formed at a position relatively closer to the effective region than the first, second and fourth portions so that one end of the wiring 300 and the third portion 530 are connected to the sensing electrode 200 in the first direction The distance between the guard portion 500 and the wiring line 300 can be ensured to be equal to or larger than the minimum tolerance for forming the wiring line 300 and at the same time the width of the ineffective area of the substrate 100 can be reduced , The object of the present invention for reducing the width of the bezel can be achieved.

The connecting portion 320 and the third portion 530 may be formed on one end of the wiring 300 so that the connecting portion 320 and the third portion 530 are electrically connected to the sensing electrode 200 ) On the first direction extension line. Since the connection portion 320 is wider than the wiring 300, the wiring 300 and the sensing electrode 200 can be easily connected to each other. The connection part 320 is also disposed between the extended lines of the first direction of the sensing electrode 200 to secure the necessary minimum tolerance between the wiring 300 and the guard part 500 and reduce the overall bezel width .

At this time, the distance between the extension of the first portion 510 in the second direction and the connection portion 320 may be smaller than the distance between the plurality of wirings 300. Even in this case, since the connection portion 320 can be separated from the guard portion 500 by at least the length of the second portion 520, the width of the manufacturing tolerance for forming the guard portion 500 and the wiring 300 is still secured And at the same time reduce the width of the bezel.

In this embodiment, the connecting portion 320 may be located between the extension of the second portion 520 in the first direction and the extension of the fourth portion 540 in the first direction. That is, the connection portion 320 is inserted into the recessed portion of the guard portion 500 (the space between the second portion 520 and the fourth portion 540 facing the third portion 530) Lt; / RTI > In this case, the bezel width can be further reduced as compared with the above-described embodiments.

In the touch panel of the present invention, the width of the connection portion 320 in the second direction may be less than the length of the third portion 530 of the guard portion 500. Therefore, the connecting portion 320 can be included in the yaw portion of the guard portion 500 according to the design purpose of the touch panel and the structure of the touch device on which the touch panel is mounted, and as a result, the degree of freedom in designing the touch panel can be improved. Meanwhile, the second portion 520 and the fourth portion 540 may be formed to have the same length. (Here, the same means substantially the same, and even though they are not completely identical, Should be regarded as including the range. Therefore, the separation distance between the wiring 300 and the guard portion 500 can be effectively reduced.

The touch panel of the present invention further includes a connection part 400 connecting one end of the first wiring 300 and one end of the sensing electrode 200 or one end of the second wiring and one end of the second sensing electrode 210 At this time, the connection part 400 may overlap the guard part 500. The connection part 400 is formed not to be directly connected to the guard part 500 and has a guard part 500 for connecting the sensing wire 200 and the wiring 300 sandwiching the guard part 500, . ≪ / RTI > An example of the specific structure can be confirmed through the sectional view of FIG.

The touch panel of the present invention may have a plurality of connection parts 400 in the ineffective area and preferably each connection part 400 may be formed for each wiring 300. The guard part 500 may include all the connection parts 400, Can be overlapped. That is, a plurality of wirings 300 and a plurality of sensing electrodes 200 are connected in a one-to-one manner. For this purpose, the number of the wirings 300 is equal to the number of the wirings 300, Since the guard portion 500 is formed between the sensing electrodes 200 of the sensing portion 200, all the connection portions 400 may be formed to overlap with the guard portion 500.
