Description

Wiring electrode for touch screen panel, touch screen panel using same and manufacturing method thereof

The present invention relates to a wiring electrode for transmitting a user's touch signal detected in a signal sensing pattern of a touch screen panel to an external driving circuit, a touch screen panel using the same, and a method of manufacturing the same. The present invention relates to a wiring electrode and a touch screen panel capable of reducing the occurrence of disconnection and a method of manufacturing the same.

In general, a touch screen panel is an input device that allows a user's command to be input by selecting instructions displayed on a screen such as an image display device with a human hand or an object. To this end, the touch screen panel is provided on the front face of the image display device to convert a contact position in direct contact with a human hand or an object into an electrical signal. Accordingly, the instruction content selected at the contact position is received as an input signal.

Since the touch screen panel can replace a separate input device connected to an image display device such as a keyboard and a mouse, its use range is gradually expanding.

The touch screen panel may be classified into a resistive type, a capacitive type, and an electromagnetic inductive type. Two representative methods are resistive and capacitive.

The resistive film is composed of two substrates coated with electrodes, and when the pressure is applied through a finger or a pen, the substrates of the portions are attached to each other to recognize the position. However, the resistive film type has gradually decreased in use due to inconvenience of operation and inaccuracy of position recognition.

In the capacitive method, when a human hand or an object comes into contact with a human body or an object, the signal sensing pattern detects a change in capacitance formed by another signal sensing pattern or ground electrode, and converts the contact position into an electrical signal. It uses the principle of detecting static electricity. Capacitive touch screen panels have the advantages of excellent durability, high permeability, and fast response time, which are the main dominant touch screen panels today.

In the capacitive touch screen panel, signal sensing patterns for detecting a touch position of a user's finger, etc. occupy most of the screen, and the touch signal generated by the signal sensing pattern drives an electronic device equipped with the touch screen panel. A wiring electrode for transferring to an external driving circuit is located at the edge of the screen.

1 is a structural diagram illustrating a connection structure of a wiring electrode of a conventional touch screen panel.

As shown in FIG. 1, in the conventional touch screen panel, an electrode pattern 3 for detecting a user's touch signal is provided at the center of the substrate 1, and externally touches the touch signal detected by the electrode pattern 3. The wiring electrode 5 which transmits to a drive circuit (not shown) is provided. The wiring electrode 5 is formed to enable the transmission of an electrical signal by forming an intaglio region in the substrate and filling a conductive material in the intaglio region.

However, the wiring electrode provided in the conventional touch screen panel has the following problems.

Due to limitations in process conditions such as adhesion, filling or printing, there is a problem in that the resistance difference varies depending on the length of the wiring electrodes. In addition, when a short circuit or disconnection occurs in some sections of the wiring electrode, there is a problem in that electrical signals cannot be transmitted. Such disconnection is mainly caused by the loss of the conductive material due to static electricity during use of the touch screen panel or the unfilling of the conductive material in the intaglio area during manufacturing of the touch screen panel.

The present invention has been made to solve the above problems, the problem to be solved in the present invention is to form a plurality of signal lines to form a wiring electrode for transmitting a signal sensed in the sensing pattern to the sensing sensor, To provide a touch screen panel wiring electrode to adjust the line width according to the length of the signal line.

Another object to be solved by the present invention is to form a wiring electrode for transmitting a signal sensed in the sensing pattern to the sensing sensor in a plurality of signal lines, the touch screen panel to connect the plurality of signal lines formed at a predetermined interval It is to provide a wiring electrode for.

Another object to be solved by the present invention is to provide a touch screen panel and a method of manufacturing the same that can effectively prevent the disconnection of the wiring electrode.

The wired electrode for the touch screen panel according to the present invention includes a contact portion electrically connected to one end of an electrode pattern generating a touch signal; A bonding part for transmitting a touch signal sensed by the electrode pattern in contact with an external driving circuit, a plurality of first signal lines connected to the contact part, and a plurality of first signals connected between the plurality of first signal lines and the bonding part; It consists of two signal lines, it characterized in that it comprises a signal line portion for connecting the contact portion and the bonding portion.

In addition, the touch screen panel according to the present invention includes a substrate; Technical features of the present invention include a plurality of electrode patterns formed on the substrate, the plurality of electrode patterns generating touch signals, and a plurality of wiring electrodes according to the present invention respectively connected to the plurality of electrode patterns.

In addition, the method for manufacturing a touch screen panel according to the present invention includes an electrode pattern forming step of forming a plurality of electrode patterns by filling a conductive material in an intaglio pattern formed on a substrate and a wiring electrode connected to each of the plurality of electrode patterns on the substrate. It characterized in that it comprises a wiring electrode forming step of forming a.

In the present invention, the wire electrode for the touch screen panel forms a wire electrode for transmitting a signal sensed in the detection pattern to the detection sensor as a plurality of signal lines, and adjusts the line width or the plurality of wire widths according to the lengths of the formed signal lines. By connecting between the signal lines at regular intervals, there is an effect that can reduce the resistance generated in the signal line.

In addition, the line width is adjusted according to the lengths of the plurality of signal lines, thereby reducing the resistance variation generated according to the length of each channel.

In addition, since a plurality of signal lines are formed to be connected at predetermined intervals, there is an effect of minimizing disconnection even when one signal line is shorted.

Hereinafter, a wire electrode and a touch screen panel for a touch screen panel according to the present invention will be described in more detail with reference to the accompanying drawings.

In describing the elements of the present invention, elements having the same name may be given different reference numerals according to the drawings, and the same reference numerals may be given even though they are different drawings. However, even in such a case, it does not mean that the components have different functions according to the embodiments, or does not mean that they have the same functions in different embodiments, the function of each component is a corresponding implementation Judgment should be made based on the description of each component in the form.

In the present invention, the wiring electrode for transmitting the signal sensed in the sensing pattern to the sensing sensor is formed of a plurality of signal lines, the line width is adjusted according to the length of the plurality of the formed signal lines or a predetermined interval between the plurality of signal lines The structure of the wiring electrode for the touch screen panel to be connected is proposed.

In addition, a structure of a wiring electrode for a touch screen panel that can effectively prevent disconnection of an electrode pattern and a wiring electrode is proposed.

2A to 2B are structural diagrams showing an overall configuration of a touch screen panel including a wire electrode for a touch screen panel according to the present invention.

2A and 2B, the touch screen panel according to the present invention includes a base or substrate 100, an electrode pattern 200, and a wiring electrode 300, and includes a resistance measurement terminal 400. It may further include.

The substrate 100 is a region of the substrate on which the electrode pattern 200 and the wiring electrode 300 are formed, and may be used without limitation of materials such as a transparent film, a glass substrate, and a plastic substrate. In particular, the substrate 100 may be formed of a transparent film. The transparent film may be formed of at least one of polyethylene terephthalate (PET), polyimide (PI), acryl, acrylic naphthalate (PEN), or glass. Can be formed.

The electrode pattern 200 is provided on the substrate 100 to sense a touch signal of the user.

The wiring electrode 300 is a component that transfers the touch signal sensed from the electrode pattern 200 to a detection sensor (not shown) of the external driving circuit, and is connected to the electrode pattern 200 formed on the substrate 100.

The wire electrode 300 is a contact part 320 electrically connected to the electrode pattern 200 and a bonding part 340 in contact with an external driving circuit (not shown) to transmit a touch signal sensed by the electrode pattern 200. , And a signal line part 360 connecting the contact part 320 and the bonding part 340.

The contact part 320 is a pad contacting one end of the electrode pattern 200 and is electrically connected to the electrode pattern 200, and may be formed of a conductive material capable of transmitting an electrical signal.

The bonding unit 340 may be formed at an end of the substrate 100 to transmit an electrical signal to an external driving circuit. In addition, the line width of the bonding unit 340 may be wider than the line width of the signal line unit 360. The reason for forming the line width of the bonding unit 340 wider than that of the signal line unit 360 is to allow the external driving circuit to be more stably connected to the bonding unit 340. That is, a conductive connection line corresponding to the bonding part 340 is formed in the external driving circuit, and the conductive connection line and the bonding part 340 have a somewhat wider line width than the case where the wire connection part has a fine line width like the signal line part 360. This is because a more stable electrical connection is possible in the case of having.

The signal line part 360 is a line connecting the contact part 320 and the bonding part 340 and is formed of a conductive material to enable transmission of an electrical signal between the contact part 320 and the bonding part 340.

2A and 2B, the signal line unit 360 may include a first signal line 362 connected to the contact unit 320 and a second signal connected between the first signal line 362 and the bonding unit 340. Line 364. The first signal line 362 is connected to the contact unit 320 to transmit an electric signal near the edge of the touch screen panel, and the second signal line 364 is connected to the first signal line 362 to connect the touch screen. It may be referred to as a line that transmits an electrical signal to the bonding unit 340 along the edge of the panel. The reason why the signal line unit 360 is generally disposed at the edge of the touch screen panel is that in the case of an electronic device including a touch screen panel, a part of a case called a bezel covers the edge of the touch screen panel. The signal line unit 360 is positioned below the bezel to secure a large touch screen screen.

The signal line unit 360 may be spaced apart by a predetermined interval so that a plurality of signal lines may be formed in parallel. For example, in the signal line unit 360, three first signal lines 362 may be formed in parallel, and two second signal lines 364 may be connected to the first signal line 362 in parallel.

Although the number of the first signal lines and the number of the second signal lines are different from each other, the present invention is not limited thereto and may be formed in various shapes as necessary.

The contact portions 320 may be spaced apart by a predetermined interval so that the plurality of contact lines 322 may be formed in parallel with the contact surface of the electrode pattern 200. A bridge 324 may be formed between the contact lines 322 at predetermined distances.

The contact lines 322 constituting the contact portion 320 may be formed perpendicular to the first signal line 362.

At this time, the first signal line 362 is formed to be connected to the bridge 324 formed in the contact portion 320, so that the first signal line 362 and the bridge 324 of the contact portion 320 is located on the same line, That is, it is preferable that it is formed in the shape of one line. When the bridge 324 and the first signal line 362 are located on the same line, the electrical resistance is reduced, so that the flow of the signal detected from the electrode pattern 200 is smoother than when the other lines are located on the same line.

The number of the bridges 324 may be the same as the number of the first signal lines 362, but the number of the bridges 324 is not necessarily limited thereto and may be less than or greater than the number of the first signal lines 362 as needed.

The resistance measurement terminal 400 is formed at an end portion to which the wiring electrode 300 of the electrode pattern 200 is not connected, and is used to detect whether the electrode is disconnected or the resistance is increased.

Specifically, disconnection and short circuit of the electrode pattern 200 or the signal line unit 360 connected to the bonding unit 340 using the voltage measured at the resistance measuring terminal 400 while applying an AC signal to the bonding unit 340. It can be determined. For example, when the voltage measured by the resistance measuring terminal 400 is measured to be lower than the preset normal value, it may be determined that the electrode pattern 200 is disconnected, and when the measured voltage is measured higher than the normal value, the electrode pattern ( It may be determined that a short circuit has occurred between them.

3A to 3B illustrate a first embodiment of a wiring electrode for a touch screen panel according to the present invention.

As shown in FIGS. 3A and 3B, the plurality of first and second signal lines 362 and 364 of the wiring electrode 300 may be spaced apart by a predetermined interval and connected in parallel.

For example, as illustrated in FIG. 3A, three first signal lines 362 connected to the contact unit 320 are formed in parallel and spaced apart by a predetermined interval, and two second units connected to the bonding unit 340 are provided. The signal lines 362 may be spaced apart by a predetermined interval and formed in parallel.

3B shows a plurality of contact lines 322 spaced apart at predetermined intervals in parallel to the contact surface of the electrode pattern 200 in parallel, and a bridge 324 connected at predetermined distances between the contact lines 322. A plurality of first and second signal lines 362 and 364 are spaced apart by a predetermined distance from the formed contact portion 320 and are connected in parallel.

In this case, the line width w of each of the plurality of first and second signal lines 362 and 364 is preferably formed to be 100 μm or less, and the separation distance d between the first or second signal lines is represented by the following equation. 1] is preferable.

Equation 1

4A to 4B are modifications of the first embodiment of the wired electrode for the touch screen panel according to the present invention.

As shown in FIGS. 4A and 4B, the wiring electrodes 300 are connected in parallel with the plurality of first and second signal lines 362 and 364 spaced apart by a predetermined interval, respectively, and the first and second signal lines. Since the resistances vary depending on the lengths of the 362 and 364, the line widths of the first and second signal lines 362 and 364 may be relatively adjusted. This is the same as the line widths of the signal line units 360 having different lengths are relatively adjusted.

As an example, as shown in FIG. 4A, the thinnest line width of the first shortest signal line part 360a is formed, and the second narrowest line width of the second signal line part 360b is thinner. The line width of the signal line part 360c, which is the third shortest in length, may be formed to be thinner.

In other words, the line width of the signal line portion 360a having the length l1 is w1, the line width of the signal line portion 360b of the length L2 signal is w2, and the line width of the signal line portion 360c of the length L3 is w3, and the relative relationship between the lengths is If l1 <l2 <l3, the relative relationship between the line widths is w1 <w2 <w3.

That is, the shorter the length of the signal line part 360, the narrower the line width of the signal line part 360, and the longer the length of the signal line part 360, the wider the line width of the signal line part 360, the greater the width of each signal. Resistance variation between the line parts 360 may be reduced.

Here, an example of controlling the resistance variation between channels by adjusting the line width of each signal line unit is described, but is not necessarily limited thereto, and the size of the signal line unit, the separation distance between the signal line units, and the first and second signal lines as necessary. Any structure may be used as long as it can reduce the resistance variation between the signal line units 360 by adjusting the number of the units.

In addition, as illustrated in FIG. 4B, the contact portions 320 may be spaced apart by a predetermined interval so that a plurality of contact lines 322 may be formed in parallel, and a bridge 324 may be formed to be connected at predetermined distances between the lines. have.

5A to 5C show another modification of the first embodiment of the wired electrode for the touch screen panel according to the present invention.

Referring to FIG. 5A, the plurality of first and second signal lines 362 and 364 are connected in parallel with each other by a predetermined interval, and the first and second signal lines 362 and 364 are connected to each other. It may be a bridge structure that is connected between each interval.

For example, the first signal lines 362 may be spaced apart by a predetermined interval and connected in parallel, and the second signal lines 364 may be spaced apart by a predetermined interval and connected in parallel, but between the second signal lines 364. Bridges 366 may be formed to be connected at regular intervals.

On the contrary, a bridge 366 may be formed in which the first signal lines 362 are spaced apart by a predetermined interval and connected in parallel, and are connected at regular intervals between the first signal lines 362, and the second signal line 364 may be spaced apart by a predetermined interval and connected in parallel.

Referring to FIG. 5B, when the wiring electrode 300 is formed in the pattern shown in FIG. 5A, when a short circuit C occurs in some sections A of the second signal lines 364, a short circuit signal line occurs. A signal line 364b in which 364a is not used and a short circuit does not occur may be used instead.

As such, the wire electrode for the touch screen panel according to the present invention can minimize the occurrence of disconnection by forming the bridge 366 on the first or second signal lines 362 and 364.

In FIG. 5C, the first and second signal lines 362 and 364 of the wiring electrode 300 are spaced apart by a predetermined interval and connected in parallel to each other, and the first and second signal lines 362 and 364 are fixed to both the first and second signal lines 362 and 364. A pattern is shown in which bridges 366 are formed that connect at intervals.

That is, a bridge 364 is formed in which the first signal lines 362 are spaced apart by a predetermined interval and connected in parallel, and are connected at regular intervals between the first signal lines 362 and the second signal lines 364. In addition, the bridges 366 are spaced apart by a predetermined interval and connected in parallel, and are connected at regular intervals between the second signal lines 364.

Therefore, when disconnection occurs in some sections of the first or second signal lines 362 and 364, a signal line in which disconnection occurs is not used, and instead, a signal line in which disconnection does not occur may be used.

In this case, an interval of the bridge 366 formed between the first signal lines 362 and an interval of the bridge 366 formed between the second signal lines 364 may be formed to be the same or different from each other.

6A to 6B are still further modifications of the first embodiment of the wired electrode for the touch screen panel according to the present invention.

FIG. 6A illustrates a pattern in which bridges 324 and 366 are formed on the contact portion 320 and the second signal line 364, respectively. FIG. 6B illustrates the contact portion 320 and the first and second signal lines 362 and 364. Shows a pattern in which bridges 324 and 366 are formed, respectively.

7 shows a bridge of the present invention.

As shown in FIG. 7, the distance L between the bridges is formed in the range of 300 μm to 500 μm, the length of the bridge or the distance D between the lines is formed in the range of 20 μm to 60 μm, and the line width W of the line is It may be formed in the range of 10㎛ ~ 40㎛.

The implementation of such a bridge may be applied to both the contact unit 320 or the signal line unit 360.

8 shows a resistance measurement terminal of the present invention.

As shown in FIG. 8, the resistance measurement terminals 400 are spaced apart by a predetermined interval so that a plurality of terminal lines 420 are formed in parallel, and the bridges 440 connected at predetermined distances between the terminal lines 420. ) May be formed.

In this case, the size of the resistance measurement terminal 400 may be adjusted to prevent an interference error between the resistance measurement terminals 400. That is, the distance between the resistance measurement terminals 400 may be spaced apart by a predetermined distance.

For example, the width l of the resistance measurement terminal 400 may be formed to be narrower than the width L of the contact surface of the electrode pattern 200 by a predetermined length. That is, as the difference between the width l of the resistance measuring terminal 400 and the width L of the contact surface of the electrode pattern 200 increases, the distance between the resistance measuring terminals becomes larger.

At this time, the difference (Ll) of the width (l) of the resistance measuring terminal 400 and the width (L) of the contact surface of the electrode pattern 200 may be formed the same, for example, 50㎛ ~ 150㎛ range desirable. In addition, it is preferable that both ends of the width of the resistance measurement terminal 400 is spaced apart from both ends of the width of the contact surface of the electrode pattern 200 by the same distance so that the resistance measurement terminal 400 and the electrode pattern 200 are centrally aligned.

Next, a description will be given of a wiring electrode structure for a touch screen panel which can effectively prevent the disconnection of the wiring electrode while increasing the manufacturing efficiency of the touch screen panel.

The disconnection of the wiring electrode is mainly caused by the use of the touch screen panel, the static electricity during manufacture, or the intaglio formed in the substrate during the manufacture of the touch screen panel, in which the conductive material is not properly filled, that is, discontinuous filling.

In order to understand, first, a method of manufacturing a touch screen panel will be described, and then a wiring electrode for a touch screen panel according to the present invention, which can improve the manufacturing efficiency and prevent disconnection of the wiring electrode, will be described.

9A to 9B illustrate a conductive material filling step in the manufacturing process of the touch screen panel. Generally, as shown in FIGS. 9A to 9B, the conductive pattern is filled into the intaglio pattern by using a roller, a doctor blade, or the like while the substrate on which the intaglio pattern is formed is moved, thereby forming the electrode pattern 200, the wiring electrode 300, A ground electrode (not shown) or the like is formed. However, when the intaglio pattern is perpendicular or horizontal to the conveying direction of the substrate, the filling of the conductive material may not be performed properly, and disconnection may occur frequently. In addition, even after the filling of the conductive material, even when the cleaning is performed, if the intaglio pattern is perpendicular or horizontal to the conveying direction of the substrate, the conductive material in the intaglio pattern is wiped out together, resulting in a low filling property. Therefore, in the related art, as shown in FIG. 9A, the intaglio pattern lattice of the electrode pattern 200 is disposed in an oblique direction with respect to the advancing direction of the substrate so that the intaglio pattern forms a predetermined acute angle with the advancing direction of the substrate. .

However, although the filling of the conductive material is good in the electrode pattern 200 in the arrangement as shown in FIG. 9A, since the wiring electrode 300 disposed in parallel with the outer side of the substrate is still disposed in the bezel area, the wiring electrode 300 is still in the transfer direction of the substrate. Since it is disposed vertically or horizontally, there is a problem in that filling of the conductive material to the wiring electrode 300 is poor or a disconnection occurs when the conductive material is wiped off during cleaning. FIG. 9B illustrates a case in which the substrate is disposed in an oblique direction with respect to the transfer direction of the substrate, and since the substrate 100 is arranged in a diagonal direction, the batch density of the substrate 100 is lowered, thus producing efficiency per unit time. In addition to falling, there is a complicated problem of disposing and operating conductive material filling means such as a roller or a doctor blade.

The wiring electrode for the touch screen panel according to the present invention is to improve the process inefficiency and to effectively prevent disconnection of the conductive material, and FIG. 10 shows a second embodiment of the wiring electrode for the touch screen panel according to the present invention. It shows a touch screen panel having a.

The wire electrode for the touch screen panel according to the present invention is provided in the touch screen panel including the substrate 100 and the electrode pattern 200 to transmit an electrical signal sensed by the electrode pattern 200 to an external driving circuit. As an electrode, '∧' and '∨' are connected to the electrode pattern 200 and include a pattern in which '∧' and '∨' are alternately continuous so as not to be parallel to the outline of the substrate 100, and are disposed along the outline of the substrate 100. It is done. Therefore, most of the wire electrode for the touch screen panel according to the present invention is formed in a zigzag pattern adjacent to the outline of the substrate 100.

11 and 12 are partially enlarged views of FIG. 10, and enlarged areas B and C of FIG. 10, respectively. The wire electrode 300 for the touch screen panel according to the present invention contacts the contact portion 320 and the external driving circuit (not shown) electrically connected to the electrode pattern 200 to receive a touch signal detected by the electrode pattern 200. The signal line unit 360 includes a bonding unit 340 to transmit, a contact unit 320, and a zigzag pattern connecting the bonding unit 340. Since the contact unit 320 and the bonding unit 340 are the same as those of the first embodiment of the touch screen panel according to the present invention, redundant description thereof will be omitted.

Similar to the first embodiment, the signal line unit 360 includes a first signal line 362 connected to the contact unit 320 and a second signal line connected between the first signal line 362 and the bonding unit 340. It can be divided into (364). At this time, the first signal line 362 is preferably composed of a conductive grating that is not parallel to the outline of the substrate 100 (so that the intaglio pattern is oblique to the transfer direction of the substrate when filling the conductive material).

The second signal line 364 is formed to include a zigzag pattern along the outline of the substrate 100. In this case, one end of the second signal line 364 connected to the first signal line 362 may protrude from the first signal line 362 to form a protruding end 363. The reason for forming the protruding end 363 is to cause discharge to occur at the protruding end 363 whenever static electricity is generated in the use and manufacture of the touch screen panel (because charges are collected at the peaks). This is to prevent the loss of the conductive material due to the electrostatic discharge (it may be accompanied by a change in the resistance value even if not disconnection or disconnection). In addition, the second signal line 364 may be filled in the intaglio pattern in which the protrusion P is formed, thereby preventing departure from the substrate 100 (the upper end of the protrusion may protrude above the second signal line, thereby forming the second signal line. Serves to fix the conductive material forming).

The touch screen panel according to the present invention includes a substrate 100, an electrode pattern 200, and a wiring electrode 300 including a zigzag pattern along an outline of the substrate 100, and includes a resistance measuring terminal 400 and a ground. The electrode 500 and the discharge electrode 600 may be further included.

Since the substrate 100 is the same as the first embodiment of the touch screen panel according to the present invention, the overlapping description is omitted.

The electrode pattern 200 is provided on the substrate 100 to sense a user's touch signal, and the intaglio formed on the electrode pattern 200 is preferably formed not to be parallel to the outline of the substrate 100 ( Like the first signal line, the intaglio pattern is oblique to the conveying direction of the substrate when the conductive material is filled).

The wiring electrode 300 may include a contact part 320 electrically connected to the electrode pattern 200, a bonding part 340 contacting an external driving circuit (not shown) and transmitting a touch signal sensed by the electrode pattern 200. It is composed of a signal line unit 360 including a zigzag pattern connecting the contact unit 320 and the bonding unit 340 as described above.

The resistance measurement terminal 400 is the same as that of the first embodiment of the touch screen panel according to the present invention. However, it may be used for the purpose of electrostatic discharge according to the coupling relationship with the discharge electrode 600, it is preferable to have a pointed tip 460.

The ground electrode 500 is a component for supplying a discharge of static electricity during manufacture and a ground voltage during operation of the touch screen panel, and includes a zigzag pattern (the same as the reason why the wiring electrode is formed including the zigzag pattern). In the case of the ground electrode 500, the outermost part of the substrate 100, that is, the outer part of the electrode pattern 200, the wiring electrode 300, the resistance measurement terminal 400, and the discharge electrode 600 is formed. It is advantageous in terms of arrangement with the fields.

The discharge electrode 600 is formed at the other end of the side of the electrode pattern 200 that is not connected to the wiring electrode 300, that is, the end of the electrode pattern 200 connected to the wiring electrode 300 at one end thereof. Electrostatic discharge induced in the electrode pattern 200 is a component. Therefore, it is desirable to have a pointed tip 620 to facilitate electrostatic discharge. The discharge electrode is disposed to face the electrode pattern 200, or to the resistance measurement terminal 400 when the resistance measurement terminal 400 is provided. When the tip 460 is provided at the resistance measuring terminal 400, it is advantageous to discharge the tip 620 of the discharge electrode 600 and the tip 460 of the resistance measuring terminal 400 to face each other. However, for convenience of manufacturing, as shown in FIG. 12, the electrode of the grid pattern may be cut to form the tip 620 of the discharge electrode 600 and the tip 460 of the resistance measurement terminal 400 to be shifted from each other. have.

Embodiments of the touch screen panel which can effectively prevent disconnection of the wiring electrodes together with the increase in the manufacturing efficiency of the touch screen panel will be described.

13A to 13B illustrate another method of manufacturing the touch screen panel according to the present invention. The touch screen panel according to the present invention includes a substrate 100, an electrode pattern 200 and a wiring electrode 300, the electrode pattern 200 is filled in the intaglio pattern, the wiring electrode 300 is embossed In the method of manufacturing a touch screen panel according to the present invention, an electrode pattern forming step of forming a plurality of electrode patterns by filling a conductive material in an intaglio pattern formed on a substrate and connected to each of the plurality of electrode patterns on the substrate And a wiring electrode forming step of forming the wiring electrode. In this case, the electrode pattern forming step may be conveniently performed in a roll-to-roll manner in which an electrode pattern is formed on a substrate wound on a roll and then wound on a roll.

As described above, since the filling of the conductive material is often poor when the intaglio pattern is perpendicular or horizontal to the conveying direction of the substrate, the electrode pattern 200 fills the conductive material in the existing intaglio pattern in the electrode pattern forming step. In the wiring electrode forming step, the wiring electrode 300 is embossed by any one of screen printing (photosensitive film printing), jet printing, gravure printing, and photolithography after the electrode pattern 200 is formed. By doing so, the problem of poor filling of the conductive material may be solved. This configuration has the advantage of easy design changes according to demand. That is, the electrode pattern 200 having a standardized shape and configuration is formed using an intaglio pattern formed by a molding or a mold, and there are various models of the product design (for example, the same 21-inch monitor exists. The wiring electrode 300 which needs to be variable according to the shape thereof is easily changed to be embossed to cope with various demands. In addition, since the wiring electrode 300 is embossed, the wiring electrode 300 may be formed in a straight line instead of zigzag.

In the above, the wiring electrode 300 and the ground electrode 500 formed as a component of the touch screen panel including the zigzag pattern along the outline of the substrate 100 have been described, but the electrodes of the zigzag pattern formed along the outline of the substrate are described. The structure can be applied to any electrode formed by filling the intaglio conductive material.
