DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description of the present invention, detailed description of related arts which may unnecessarily obscure the gist of the present invention will be omitted.

Hereinafter, with reference to the accompanying drawings will be described in detail a first embodiment of the present invention.

1 is a plan view illustrating a transparent substrate of a touch panel according to a first embodiment of the present invention, FIG. 2 is a plan view showing electrodes of a touch panel according to a first embodiment of the present invention, and FIG. 3 is shown in FIG. 4 is an enlarged plan view of a main part of the electrode, and FIG. 4 is a plan view of the main part showing a structure in which wiring is connected to the electrode shown in FIG. 2.

1 to 4, the touch panel according to the first embodiment of the present invention includes a transparent substrate 100, an electrode 200 formed in a mesh pattern on the transparent substrate 100, and And a wire 300 formed in a zigzag pattern on the transparent substrate 100 and having a first peak and a second peak that are alternately continuous in a longitudinal direction and connected to the electrode 200.

The transparent substrate 100 serves to provide an area where the electrode 200 and the wiring 300 are to be formed. The transparent substrate 100 should have a supporting force capable of supporting the electrode 200 and the wiring 300 and transparency for allowing a user to recognize an image provided by the image display apparatus.

The transparent substrate 100 may be formed of a material selected from the group consisting of polyethylene terephthalate (PET), polycarbonate (PC), polymethylmethacrylate (PMMA), polyethylene naphthalate (PEN), polyethersulfone (PES) , Cyclic olefin polymer (COC), TAC (triacetylcellulose) film, polyvinyl alcohol (PVA) film, polyimide (PI) film, polystyrene (PS), biaxially oriented polystyrene oriented PS (BOPS), glass or tempered glass, but is not limited thereto.

Meanwhile, the transparent substrate 100 may be a window provided on the outermost side of the touch panel. When the transparent substrate 100 is a window, since the electrode 200 to be described later is directly formed on the window, the manufacturing process of the touch panel is a process in which the electrode 200 is formed on a separate transparent substrate 100 and then attached to the window. May be omitted, and the overall thickness of the touch panel may be reduced.

As illustrated in FIG. 1, the transparent substrate 100 may be divided into an active region 101 and an inactive region 102 disposed outside the edge of the active region 101. The active area 101 is an area where a touch action by the user is made, and is a screen area where the user visually checks an operation scene of the touch panel. The non-active area 102 is an area not covered by the bezel part (not shown) having a black or white color formed on the edge of the transparent substrate 100 or the edge of the window.

The electrode 200 serves to generate a signal when a user touches and to recognize touch coordinates in a controller (not shown). The signal generated from the electrode 200 is transmitted to the controller (not shown) through the wire 300 to be described later.

The electrode 200 is formed in a mesh pattern on the transparent substrate 100. As a specific example, the mesh pattern forming the electrode 200 may be formed as a pattern in which parallelogram patterns P having the same shape are continuously arranged. 2 and 3 illustrate an example in which the parallelogram pattern P has a rhombus shape. However, the parallelogram pattern P is not necessarily the same length of the four sides.

The column pattern F of the electrode 200 may be formed of a plurality of parallelogram patterns P continuously arranged in a longitudinal direction with reference to FIG. 2. In this case, the plurality of parallelogram patterns P may be arranged continuously in the first direction such that the first diagonal line D1 of the parallelogram pattern P continues on the same line in the first direction to form the thermal pattern F. Can be. In addition, the electrode 200 may have a pattern in which the column pattern F is arranged in a horizontal direction perpendicular to the first direction, that is, in the transverse direction with reference to FIG. 2.

Hereinafter, for convenience of description, the first column pattern in order from the column pattern F of the electrode 200 disposed at the end of one side of the electrode 200, for example, the left side of the electrode 200 based on FIG. 3. (F1), second column pattern F2, third column pattern F3, and so on.

The wire 300 is electrically connected to the electrode 200 to transmit a touch signal generated from the electrode 200 to the controller. One end of the wiring 300 may be connected to the electrode 200, and the other end thereof may be positioned in the inactive region 102 of the transparent substrate 100 illustrated in FIG. 1. A flexible printed circuit board (FPCB) connected to the controller may be electrically connected to the other end of the wiring 300.

On the other hand, when the electrode is formed in a mesh pattern, if the wiring connected to the electrode is formed in a straight line as in a conventional touch panel structure, the wiring cannot be disposed in the active region 101 of the transparent substrate 100. This is because the wiring does not have a uniform shape with the pattern for forming the electrode, and the visibility of the touch panel is poor.

Therefore, the wiring formed in a straight line is inevitably formed in the non-active area 102, and thus, the conventional touch panel has a disadvantage in that the non-active area 102 is formed wide.

According to the present invention, the wiring and the electrode form a uniform pattern as a whole, so that even if the wiring is disposed in the active region 101 of the transparent substrate 100, the good visibility of the touch panel is maintained and the inactive region 102 is reduced. It is a challenge.

In this embodiment, to solve the above problem, the wiring 300 is formed in a zigzag pattern on the transparent substrate 100 as shown in FIG. 4. The reason why the wiring 300 is formed in a zigzag pattern is as follows.

When the first column pattern F1 illustrated in FIG. 3 is half-sided, it can be seen that the left portion of the first column pattern F1 has a zigzag shape in which mountains and valleys are continuously formed along the longitudinal direction. Therefore, the wiring 300 is formed in a shape corresponding to the zigzag shape formed along the longitudinal direction on the left side of the first column pattern F1, and suitably corresponds to a mesh pattern for forming the electrode 200 on the transparent substrate 100. If formed in a harmonious position, the electrode 200 and the wiring 300 may form a uniform pattern as a whole. If the electrode 200 and the wiring 300 are seen as a uniform pattern as a whole, even if the wiring 300 is formed in the active region 101 of the transparent substrate 100 together with the electrode 200, the visibility of the touch panel is improved. There is no problem of deterioration.

To this end, the wiring 300 is formed in a zigzag pattern. The wiring 300 is formed in a zigzag pattern to form hills and valleys alternately continuous along the longitudinal direction, wherein one of the hills and valleys becomes the first peak 301, and the other is the second peak 302. Becomes

The wiring 300 may be formed at various positions on the transparent substrate 100 which may be seen in a uniform pattern together with the electrode 200. As a specific example of the arrangement position of the wiring 300, the wiring 300 is disposed to be close to the first column pattern F1 forming the left side of the electrode 200 and is transparent to have a longitudinal direction in the first direction. It may be formed on the substrate 100.

In this case, the wire 300 may be connected to the first column pattern F1 of the electrode 200 by a separate connection line (not shown). Alternatively, as illustrated in FIG. 4, the first peak 301 of the wiring 300 facing the first column pattern F1 may be directly connected to the first column pattern F1. In more detail, the parallelogram pattern P forming the first column pattern F1 has one of the vertices Va positioned in the direction of the second diagonal line D2 (see FIG. 2). It is located close to (300) side. As illustrated in FIG. 4, the wiring 300 may be connected to the electrode 200 by directly connecting the vertex of the first peak 301 to the vertex Va.

In addition, only one of the plurality of first peaks 301 formed along the longitudinal direction may be connected to the first column pattern F1, or as illustrated in FIG. 4, the wiring 300 may include the plurality of first peaks. 301 may be connected to the plurality of vertices Va of the first column pattern F1, respectively. To this end, the width W1 between the first peaks 301 of the wiring 300 may be equal to the width of the first diagonal line D1 of the parallelogram pattern P. FIG.

Furthermore, the wiring 300 is generally parallel to one side P1 of the parallelogram pattern P facing the line L12 from the first peak 301 to the second peak 302, and the second peak. A line L21 leading to the first peak 301 at 302 may be formed substantially parallel to the other side P2 of the parallelogram pattern P facing each other. In this case, the wiring 300 may have a width W2 having a width corresponding to 1/2 of the width W3 of the column pattern F or a width close to 1/2 of the width W3 of the column pattern F. Can have As the wiring 300 is formed in this manner, the wiring 300 may be matched with the mesh pattern forming the electrode 200, and the wiring 300 and the electrode 200 may form a uniform pattern as a whole.

On the other hand, the electrode 200 and the wiring 300 described above may be made of a metal having high electrical conductivity and easy processing. As the metal, for example, a metal made of copper (Cu), aluminum (Al), gold (Au), silver (Ag), titanium (Ti), palladium (Pd), chromium (Cr), or a combination thereof may be used. The electrode 200 and the wiring 300 may be formed on the transparent substrate 100 through various methods such as a plating process or a deposition process. In this case, the electrode 200 and the wiring 300 may be integrally formed. Do.

In addition, the electrode 200 and the wiring 300 may be formed of metal silver formed by exposing / developing a silver salt emulsion layer in addition to the above-described metal.

Hereinafter, a second embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, content overlapping with the content described in the first embodiment will be omitted below.

FIG. 5 is a plan view showing main parts of an electrode array and a wiring array of a touch panel according to a second exemplary embodiment of the present invention. FIG. 6 is an enlarged view illustrating main parts of the wiring array shown in FIG. 5 and FIG. 8 is an enlarged view illustrating main parts of another example of the wiring array, and FIG. 8 is an enlarged view illustrating main parts of the wiring array illustrated in FIG. 5.

As shown in FIGS. 5 to 8, the touch panel according to the present embodiment is formed in a mesh pattern on the transparent substrate 100 and the transparent substrate 100, and is formed in the mesh pattern. The incision 401 is formed, and the electrode array 400 partitioned into the first electrode 410 and the second electrode 420, and formed in a zig-zag pattern on the transparent substrate 100 along the longitudinal direction A first wiring 510 and a second wiring 520 having alternately continuous first peaks 511 and 521 and second peaks 512 and 522, wherein the first wiring 510 is the first electrode 410. ) And the second wiring 520 includes a wiring array 500 connected to the second electrode 420.

The electrode array 400 is formed in a mesh pattern on the transparent substrate 100 as shown in FIG. 5. The mesh pattern forming the electrode array 400 may be formed while occupying a predetermined region in the active region 101 of the transparent substrate 100.

The electrode array 400 may be divided into the first electrode 410 and the second electrode 420 while the cutout 401 is formed in the mesh pattern forming the electrode array 400. Alternatively, the electrode may be partitioned into three or more electrodes including the first electrode 410 and the second electrode 420.

FIG. 5 illustrates an example in which a cutout 401 is formed in a mesh pattern forming the electrode array 400 and divided into a first electrode 410 and a second electrode 420. In this case, the first electrode 410 and the second electrode 420 are disposed in the longitudinal direction.

The first electrode 410 and the second electrode 420 may be partitioned from each other while the mesh pattern formed between the first electrode 410 and the second electrode 420 is broken, and the cutout 401 is broken. Means a site.

The mesh pattern forming the electrode array 400 is the same as the mesh pattern forming the electrode 200 of the first embodiment. In addition, the electrodes 410 and 420 partitioned from the electrode array 400 may have various contours.

As described above, the wiring array 500 includes a first wiring 510 connected to the first electrode 410 when the electrode array 400 is divided into a first electrode 410 and a second electrode 420. The second wire 520 may be connected to the second electrode 420. In addition, the wiring array 500 may include the first wiring 510 and the second wiring 520 when the electrode array 400 is divided into three or more electrodes including the first electrode 410 and the second electrode 420. It may consist of three or more wirings including the first wiring 510 and the second wiring 520.

The first wiring 510 and the second wiring 520 are similar to the wiring 300 (refer to FIG. 4) described in the first embodiment, and as shown in FIGS. 5 and 6, the first peaks 511 and 521 and the second wiring 520 are formed. It is formed in a zigzag pattern having two peaks (512, 522).

Here, the first wiring 510 is connected to the first electrode 410. For example, the first wiring 510 may be disposed to be close to the first column pattern 1F1 of the first electrode 410, and may have a longitudinal direction in a longitudinal direction based on a first direction, for example, FIG. 5. The first wire 510 may be directly connected to a vertex Va near the first peak 511 of the first column pattern 1F1 of the first electrode 410.

The second wiring 520 is connected to the second electrode 420. The second wiring 520 may be disposed to be close to the first column pattern 2F1 of the second electrode 420, and may be formed in a longitudinal direction thereof, and the second wiring 520 may also be formed in the first wiring 510. Similarly, the first peak 521 may be directly connected to the vertex Va adjacent to the first column pattern 2F1 of the second electrode 420.

At this time, the second electrode 420 is formed in the first column pattern so that the second wire 520 is formed in the length direction parallel to the length direction of the first wire 510 and does not overlap the first wire 510. 2F1 may be formed to protrude laterally than the first column pattern 1F1 of the first electrode 410. That is, as shown in FIG. 5, in the second electrode 420, the second column pattern 2F2 of the second electrode 420 is aligned with the first column pattern 1F1 of the first electrode 410. In this case, the second electrode 420 has a shape in which the left side protrudes to the left by half the width of the column pattern F more than the left side of the first electrode 410. Accordingly, the second wiring 520 may be directly connected to the first column pattern 2F1 of the second electrode 420 and may be formed in parallel without overlapping the first wiring 510 even though the second wiring 520 has a longitudinal direction in the longitudinal direction. Can be.

Meanwhile, reference numeral 530 shown in FIG. 5 denotes a connection pattern connected to the vertex Vb of the parallelogram pattern P positioned at the top of the first column pattern 2F1 at the end of the first wiring 510. It is. As described above, since the left side of the second electrode 420 protrudes to the left side more than the first electrode 410, the end portion of the first wiring 510 and the first column pattern of the second electrode 420 are formed. A space in which the patterns are not continuous may be formed between the 2F1s. Such a space may be a factor that degrades the visibility of the touch panel. Accordingly, a connection pattern 530 having a shape in which the pattern of the first wiring 510 is continuous at the end of the first wiring 510 is formed, and the connection pattern 530 is the first of the second electrode 420. By being connected to the vertex Vb of the parallelogram pattern P of the column pattern 2F1, the electrode array 400 and the wiring array 500 may form a uniform pattern as a whole without forming the above-described space. In this case, the connection pattern 530 may be formed with a cutout 531 as shown to insulate between the first wiring 510 and the second electrode 420.

In the first wiring 510 and the second wiring 520, a plurality of first peaks 511 and 521 may be directly connected to the plurality of vertices Va of the first column patterns 1F1 and 2F1, respectively. For this purpose, the width between the first peak 511 of the first wiring 510 (1W1, see FIG. 6) and the width between the first peak 521 of the second wiring 520 (2W1, see FIG. 6) are parallelograms. It may be equal to the width of the diagonal line D1 of the pattern (P).

Further, the first wires 510 and the second wires 520, like the first embodiment, may have a first peak 511, 521 so that the electrode array 400 and the wire array 500 can be seen in a uniform pattern as a whole. ) May be generally parallel to one side of the parallelogram pattern P facing each other, and the lines leading from the second peak 512,522 to the first peak 511,521 may be parallel to each other. It may be generally parallel with other sides of the quadrilateral pattern P. FIG.

Meanwhile, as illustrated in FIGS. 5 and 6, the transparent substrate 100 may have an adjacent section S in which the first wiring 510 and the second wiring 520 are adjacent to each other and arranged in parallel. .

In this case, the adjacent sections S may be spaced apart from each other while the second peak 512 of the first wiring 510 and the first peak 521 of the second wiring 520 face each other and are insulated from each other.

However, as described above, the widths 1W1 and 2W1 between the first peaks 511 and 521 are equal to the widths of the first diagonal lines D1 of the parallelogram pattern P, and the first peaks 511 and 521 and the second peaks ( When the lines connecting 512 and 522 are formed in parallel with opposite sides of the parallelogram pattern P, and the left and right widths of the wiring array 500 are formed to be the same as the left and right widths of the column pattern F, the first wiring ( The second peak 512 of the 510 and the first peak 521 of the second wiring 520 may be connected to each other without being spaced apart from each other. Accordingly, the second peak 512 of the first wiring 510 and the first peak 521 of the second wiring 520 may be spaced apart from each other so as to be spaced apart from each other. As illustrated in FIG. 7, the first peak 521 of the second wiring 520 may be a straight portion 501 having one end portion thereof having a length in the longitudinal direction. Alternatively, as shown in FIG. 8, the second peak 512 of the first wiring 510 and the first peak 521 of the second wiring 520 may be straight portions 501. .

In the adjacent section S, the two wires 510 and 520 may be formed by the straight portion 501 having the end portions of one or both of the first peak 521 and the second peak 512 facing each other. Although the lines L12 and L21 connecting the first peaks 511 and 521 and the second peaks 512 and 522 are formed in parallel with the opposite sides P1 and P2 of the parallelogram pattern P, the first peaks 521 and the first peak are respectively formed. Space between two peaks 512 may be secured.

However, the first wire 510 or the second wire 520 does not necessarily have to be formed with the straight portion 501 in the adjacent section (S). Lines connecting the first peaks 511 and 521 and the second peaks 512 and 522 are formed at an angle different from the inclination angle of the opposite sides of the parallelogram pattern P, or the first wiring 510 and the second wiring ( By adjusting the separation distance between the wirings 520, that is, the left and right widths of the wiring array 500, the first wiring 510 and the second wiring 520, as shown in FIGS. 5 and 6, have the straight portion 501 described above. The first peak 521 and the second peak 512 may be spaced apart from each other without the formation of).

On the other hand, it is preferable that the pattern of the adjacent section S formed by the first wiring 510 and the second wiring 520 looks uniform with the mesh pattern forming the electrode array 400 as a whole.

Therefore, as described above, the widths 1W1 and 2W1 between the first peaks 511 and 521 of the first wiring 510 and the second wiring 520 are the widths of the first diagonal lines D1 of the parallelogram pattern P. FIG. The first peaks 511 and 521 and the second peaks 512 and 522 are substantially parallel to opposite sides of the parallelogram pattern P, and the first wiring 510 in the adjacent section S. FIG. In the case where the second peak 512 of the second peak 512 and the first peak 521 of the second wiring 520 are formed to face each other, the adjacent section S is formed as shown in FIG. 6. The distance PL between the first peak 511 and the second peak 522 of the second wiring 520 may be equal to the width of the second diagonal line D2 of the parallelogram pattern P. Referring to FIG. The direction of the straight line PL may coincide with the direction of the second diagonal D2 of the parallelogram pattern Pa disposed on the straight line PL direction.

As the wiring array 500 is formed in this manner, the adjacent section S has a shape in which a pattern similar to the parallelogram pattern P is continuously arranged in the longitudinal direction by the first wiring 510 and the second wiring 520. Will be Accordingly, the wiring array 500 may be seen as a uniform pattern as a whole with the electrode array 400, and even if the wiring array 500 is formed together with the electrode array 400 in the active region 101 of the transparent substrate 100, good visibility of the touch panel may be achieved. Can be maintained.

As in the first exemplary embodiment, the mesh pattern forming the electrode array 400 and the pattern forming the wiring array 500 may be formed of the same material. Specific materials and formation methods are already described in the first embodiment and will be omitted.

On the other hand, the above-described straight portion 501 is spaced at equal intervals along the longitudinal direction of the first wiring 510 or the second wiring 520, as shown in Figs. It may be arranged having a longitudinal direction.

In this case, when the external light reaches the straight portion 501, the phenomenon caused by the light generated in the straight portion 501, that is, the light absorption or the light reflection, is generated substantially the same for each spaced straight portion 501.

And, since the straight portion 501 is disposed having a longitudinal direction that can be connected to a straight line on the same line, the above-mentioned phenomenon caused by the light occurs continuously on the same line that runs in the longitudinal direction, and thus, a single line extending in the longitudinal direction. An optical path can be formed. Such an optical path may be visible to the user depending on the angle of view of the touch panel.

Thus, another example of the above-described straight portion 501 may be presented so that this problem can be solved, that is, so that one light path extending in the longitudinal direction does not occur. Hereinafter, another example of the straight portion 501 will be described in detail with reference to FIGS. 9 and 10.

FIG. 9 is an enlarged view illustrating main parts of the straight portion 501 illustrated in the area A of FIG. 8, and FIG. 10 is an enlarged view illustrating another example of the straight portion 501 illustrated in the area A of FIG. 8. It is also.

As another example of the straight portion 501 illustrated in FIGS. 7 and 8, as illustrated in FIG. 9, the protrusion 502 may be further formed at an upper side or a lower side thereof. The protrusion 502 is formed to protrude in the lateral direction while being bent at the upper side or the lower side of the straight portion 501.

As in the example shown in FIG. 9, when the end portions of both the second peak 512 of the first wiring 510 and the first peak 521 of the second wiring 520 are the straight portions 501, The protruding portion 502 may be formed in only one of the straight portion 501 of the first wiring 510 and the straight portion 501 of the second wiring 520, or as shown, the protruding portion 502 is formed in both. ) May be formed. When the protrusions 502 are formed on both of them, as illustrated, the straight portion 501 of either the first wire 510 or the second wire 520 is on the upper side and the other 510. Protruding portion 502 may be formed at the lower side of the straight portion 501. At this time, the protrusion 502 may be formed to protrude in the direction of the opposite peak (512, 521).

Although not shown, only the end portion of any one of the second peak 512 of the first wiring 510 and the first peak 521 of the second wiring 520 is the straight portion 501 (see FIG. 7). ), The above-described protrusion 502 may be formed on the straight portion 501.

Since the protrusion 502 is formed on the straight portion 501, a phenomenon such as light absorption or light reflection generated when light arrives is different from the protrusion 502 and the straight portion 501. Thus, the above-described light path, which may be formed to extend in the longitudinal direction, is not formed in the example of the straight portion 501 shown in FIG.

As another example of the straight portion 501 illustrated in FIG. 8, as illustrated in FIG. 10, the second peak 512 of the first interconnection 510 and the first peak 521 of the second interconnection 520 are illustrated. ) May be a straight portion 503 having a length in an oblique direction. However, the present invention is not limited thereto, and a straight line having a length in an oblique direction is formed only at one end portion of the second peak 512 of the first wiring 510 and the first peak 521 of the second wiring 520. It may be a part.

As shown in the illustrated example, the end portions of both the second peak 512 of the first wiring 510 and the first peak 521 of the second wiring 520 are straight portions 503 having a length in an oblique direction. In this case, the straight portions 503 facing each other may be parallel to each other. The length of the space formed between the straight portions 503 formed in parallel to each other is formed in the diagonal direction.

Therefore, according to the example of the straight portion 503 shown in FIG. 10, the straight portions 503 spaced apart along the longitudinal direction of the wiring array 500 do not have an arrangement form extending in a straight line on the same line. In addition, as described above, since the space between the straight portions 503 is formed in the longitudinal direction in a diagonal direction, the space between the straight portions 503 does not extend in a straight line form along the same length along the longitudinal direction of the wiring array 500. Do not.

For this reason, even in the case of the example of the straight portion 503 shown in Fig. 10, the above-described light path that can be formed to extend in the longitudinal direction is not formed.

As the present invention can be seen in the description of the embodiment described above, the electrode and the wiring, or the electrode array and the wiring array is formed so that the overall uniform pattern, so that the wiring or wiring array together with the electrode or the electrode array transparent substrate It can be disposed in the active area of the, thereby reducing the inactive area of the transparent substrate.
