An embodiment of the present invention relates to a touch screen panel, and more particularly, to a touch screen panel that prevents driving failure due to static electricity.

The touch screen panel is an input device that allows a user's command to be input by selecting an instruction displayed on a screen such as a video 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 directly contacting a human hand or object into an electrical signal. Accordingly, the instruction content selected at the contact position is accepted as an input signal.

Since such a touch screen panel can replace a separate input device operated by being connected to a video display device such as a keyboard and a mouse, the range of its use is gradually expanding.

As a method of implementing a touch screen panel, a resistive film method, a photo sensing method, and a capacitive method are known.

Among them, a capacitive touch screen panel converts a contact position into an electrical signal by detecting a change in capacitance that a conductive sensing electrode forms with other sensing electrodes or ground electrodes in the vicinity when a human hand or an object is in contact. do.

It comprises a second sensing electrode formed to be connected.

In general, the first connection patterns and the second connection patterns intersect with each other with an insulating film interposed therebetween, and they are relatively large in resistance since they are narrow compared to the patterns of the sensing electrodes themselves. Therefore, the intersection of the first connection pattern and the second connection pattern is likely to be damaged by static electricity.

In this way, when damage such as insulation breakage or disconnection occurs due to static electricity at the intersection of the first connection pattern and the second connection pattern, driving failure of the touch screen panel is caused.

Accordingly, an object of the present invention is to provide a touch screen panel that can be prevented from driving failure due to static electricity.

To achieve the above object, a touch screen panel according to an exemplary embodiment of the present invention includes: a plurality of first sensing electrodes formed on a substrate; Second sensing electrodes formed between the first sensing electrodes on the substrate; A plurality of first connection patterns connecting the first sensing electrodes arranged in the same row; A plurality of second connection patterns connecting the second sensing electrodes arranged in the same column; A first insulating layer formed between the first connection patterns and the second connection patterns; And protruding patterns protruding from each of the second sensing electrodes toward adjacent second sensing electrodes, one end of each of the second connection patterns being electrically connected to a corresponding protruding pattern, and the protruding patterns in a column direction.

The lower second sensing electrode may be electrically connected to the protruding patterns and the two connecting patterns.

In some embodiments, the touch screen panel may further include a second insulating layer formed entirely on the top of the touch screen panel.

In some embodiments, the touch screen panel further includes dummy patterns formed in an island shape in at least one of the first and second sensing electrodes but insulated from the first and second sensing electrodes, and at least one. The length direction of the dummy pattern may not be parallel to adjacent sides of the first and second sensing electrodes in which the at least one dummy pattern is formed on the back.

In some embodiments, the dummy patterns may be disposed adjacent to intersections of the first sensing electrodes and the second sensing electrodes.

In some embodiments, the dummy patterns may be spaced apart from the edges of the sensing electrodes on which the dummy patterns are formed.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

1 is a plan view schematically showing an example of a touch screen panel.

Referring to FIG. 1, the touch screen panel includes a substrate 10, sensing electrodes 11 formed in a touch active area on the substrate 10, and sensing electrodes formed in a touch inactive area outside the touch active area. It includes outer wirings (21) connecting the (11) to the external driving circuit through the pad portion (20).

The touch active area overlaps an image display area of a display panel (not shown) disposed under the touch screen panel and is visually recognized from the outside, and the touch inactive area overlaps the non-display area and covers the non-display area or It is not visible from the outside by the light blocking layer blocking the light.

The substrate 10 may be a transparent substrate made of a flexible material.

The sensing electrodes 11 are dispersedly disposed in a touch active area on the substrate 10 and are formed to be electrically connected along a first direction, and a plurality of first sensing electrodes 11a and the first sensing electrodes 11a ) And is disposed between the first sensing electrodes 11a so as not to overlap with a plurality of second sensing electrodes 11b formed to be electrically connected along a second direction crossing the first direction.

That is, the first sensing electrodes 11a and the second sensing electrodes 11b are alternately arranged to be connected to each other in different directions. For example, the first sensing electrodes 11a are formed to be connected along the row direction (horizontal direction) and connected to each outer wire 21 in units of row lines, and the second sensing electrodes 11b are arranged in the column direction ( It is formed to be connected along the vertical direction) may be connected to each outer wiring 21 in units of column lines.

The first sensing electrodes 11a and the second sensing electrodes 11b are formed of a transparent electrode material such as ITO so that light from a display panel (not shown) disposed underneath is transmitted.

Meanwhile, although only a simple line is shown in FIG. 1 without a sign, a plurality of first sensing electrodes 11a are arranged in a first direction (for example, a row) in a touch active area on the substrate 10 along a first direction. Direction), and a plurality of second connection patterns that are arranged along the second direction to connect the second sensing electrodes 11b in the second direction (eg, column direction). An embodiment of these connection patterns and a more detailed description thereof will be described later.

The outer wirings 21 are for connecting the first sensing electrodes 11a and the second sensing electrodes 11b with an external driving circuit in units of lines along the first direction and the second direction, respectively. It is electrically connected to the first and second sensing electrodes 12a and 12b in a row line unit and a column line unit, and is connected to an external driving circuit (not shown) such as a position detection circuit through the pad unit 20. do.

The outer wirings 21 are disposed in a touch inactive region outside the touch screen panel, avoiding a touch active region where an image is displayed, and a wide selection of materials makes the transparent electrode material used to form the sensing electrodes 11 In addition, it may be formed of a low-resistance metal material such as molybdenum (Mo), silver (Ag), titanium (Ti), copper (Cu), aluminum (Al), molybdenum / aluminum / molybdenum (Mo / Al / Mo).

The touch screen panel as described above is a capacitive touch screen panel. When a contact object such as a human hand or a stylus pen is in contact, the outer wirings 21 and the pad portion 20 are sensed from the sensing electrodes 11. The change in capacitance according to the contact position is transmitted to the driving circuit (not shown) via. Then, the contact position is grasped by the change of the electrostatic capacity to an electrical signal by the X and Y input processing circuit (not shown).

FIG. 2 is a plan view and a partially enlarged view showing a part of a touch screen panel according to an embodiment of the present invention, and FIGS. 3A and 3B are views of a touch screen panel along line II 'and line II-II' of FIG. 2 It is a main section.

For convenience, in FIG. 2, two adjacent first sensing electrodes 11a and a first connection pattern 12a connecting them, and two adjacent second sensing cells 11b and a second connection pattern 12b connecting them ). However, the actual touch screen panel has a structure in which the structure shown in FIG. 2 is repeatedly arranged in the touch active area. Therefore, hereinafter, both the first connection pattern 12a and the second connection pattern 12b will be described in a plurality of forms.

Referring to area A of FIG. 2 and FIG. 3A, the touch screen panel of the present invention is formed to be electrically connected to a substrate 10 and a touch active area on the substrate 10 along first and second directions, respectively. The plurality of first sensing electrodes 11a and the second sensing electrodes 11b and the plurality of first connection patterns 12a electrically connecting the first sensing electrodes 11a along the first direction and Between the plurality of second connection patterns 12b and the first connection patterns 12a and the second connection patterns 12b that electrically connect the second sensing electrodes 11b along the second direction. The first insulating film 30 is interposed to ensure insulation.

In some embodiments, the first insulating film 30 may be partially disposed between the first connection patterns 12a and the second connection patterns 12b, which are to be secured with insulation, and in other embodiments, the The sensing electrodes 11 may be formed entirely on the touch active area.

In addition, the second insulating film 40 may be further formed on the entire top of the touch screen panel to protect the patterns formed on the substrate 10 according to the design structure.

Here, since the touch active region is implemented transparently so that the image from the display panel side is visible, the first and second sensing electrodes 11a and 11b are formed of a transparent electrode material such as ITO, and the first and / or Alternatively, the second connection patterns 12a and 12b are formed of transparent electrode materials such as the first and second sensing electrodes 11a and 11b or formed of an opaque low-resistance metal material to prevent visualization. Its width, thickness, and length can be adjusted.

For example, the first connection patterns 12a are formed of a transparent electrode material together with the first and second sensing electrodes 11a and 11b, and the second connection patterns 12b are formed of a low-resistance opaque metal material. Can be.

In this case, the second sensing electrodes 11b are formed to have a separate pattern between the first sensing electrodes 11a, but in line units along the second direction by the second connection patterns 12b. Can be connected.

In another embodiment, the first sensing electrodes 11a are formed to have a separate pattern between the second sensing electrodes 11b, but the line along the first direction is formed by the first connection patterns 12a. It may be connected in units, which is optional, and in this embodiment, the second sensing electrodes 11b will be mainly described with an example having a separated pattern.

The first insulating layer 30 is formed locally in an area in which insulation is to be secured, such as an intersection of the first connection patterns 12a and the second connection patterns 12b, and the first insulating layers 30 are formed with the second sensing electrodes 11b. 2 The connection patterns 12b may be connected through direct contact. In this case, the contact resistance may be determined according to the size of the contact area between the second sensing electrodes 11b and the second connection patterns 12b.

In another embodiment, the second connection patterns 12b are separated and patterned on the upper or lower layers of the second sensing electrodes 11b to which they are connected, and contact holes formed at both ends of the first insulating layer 30 are formed. It may be electrically connected to adjacent second sensing electrodes 11b through (not shown).

When connecting one second sensing electrode 11b and one second connection pattern 12b, one or more contact holes may be formed, but a plurality of contact holes may be formed to reduce contact resistance, and the number of contact holes may be reduced. Can be adjusted in consideration of contact resistance and visibility.

Meanwhile, when the first connection patterns 12a are formed of a transparent electrode material, the first sensing electrodes 11a and the first connection patterns 12a are lined along the first direction from the patterning step of the transparent electrode material. The process can be simplified by integrally patterning the furnace.

Then, when the second connection patterns 12b are formed of a low-resistance opaque metal material, in the step of forming the outer wirings 21 disposed in the touch inactive region, the second connection patterns 12b and the outer The process can be further simplified by forming the wirings 21 simultaneously. That is, the second connection patterns 12b may be formed on the same layer with the same material as the outer wirings 21.

However, in the case of the second connection patterns 12b formed of a low-resistance opaque metal material, the width is limited so that visualization is prevented, so the width of the second connection patterns 12b is a transparent electrode material. It is formed narrower than the width of the first connection patterns 12a to be formed. In some embodiments, the second connection patterns 12b may be designed to be inclined in a diagonal direction so that visualization can be more effectively prevented.

As described above, since the second connection patterns 12b overlap the image display surface and are located in the touch-active area exposed to the outside, the second connection patterns 12b should be designed narrowly in consideration of visibility, in this case, the first and second connection patterns Due to static electricity concentrated on the intersections of the fields 12a and 12b, defects are likely to occur in the second connection patterns 12b, which may cause malfunction of the touch screen panel.

For example, when static electricity rapidly flows from the second sensing electrodes 11b in the low resistance region to the second connection patterns 12b in the high resistance region, insulation breakdown occurs and the second connection patterns 12b are cut off. Losing problems can occur.

Accordingly, the present invention is derived to improve the problem of driving failure of the touch screen panel due to static electricity. Referring to FIG. 2, an island shape is formed in at least one of the first and second sensing electrodes 11a and 11b. It is formed, but is electrically insulated from the sensing electrode to which it belongs, and forms dummy patterns 13 and 14 disposed adjacent to intersections of the first and second sensing electrodes 11a and 11b. .

That is, the dummy patterns 13 and 14 form a blocking region (isolated region) on the electric movement paths of the first and second sensing electrodes 11a and 11b to reduce the width of the electric movement path and reduce the length of the path. By increasing the electrical resistance of the moving path, it is possible to prevent a rapid inflow of static electricity into the high resistance region, which is the intersection of the sensing electrodes.

In some embodiments, the dummy patterns 13 and 14 are first dummy patterns 13 spaced apart from the edge of the sensing electrode to which they belong, and second dummy patterns 14 contacting the edge of the sensing electrode to which they belong. ). Here, the edge is defined as a boundary line of the first and second sensing electrodes 11a and 11b.

When the static electricity of the positive charge flows into the first dummy patterns 13, the negative charge is charged on the surface of the first dummy patterns 13 and attracts the positive charge of the static electricity to flow into the second connection patterns 12b. It plays a role in alleviating the impact caused by static electricity.

The second dummy patterns 14 extend and bypass the electrical movement path so that the introduced static electricity does not rapidly flow into the intersection of the sensing electrodes.

For example, in some regions of the first sensing electrodes 11a, first dummy patterns 13a spaced apart from the edge and second dummy patterns 14a contacting the edge are formed, and the second sensing electrodes ( First dummy patterns 13b spaced apart from the edge and second dummy patterns 14b contacting the edge may be formed in some regions of 11b).

The dummy patterns 13 and 14 are disposed on the same layer as the first and second sensing electrodes 11a and 11b, and may be made of the same material. For example, the dummy patterns 13 and 14 may be patterned together with transparent electrode materials such as the first and second sensing electrodes 11a and 11b.

In addition, an insulating property may be secured by interposing a first insulating film 30 between the dummy patterns 13 and 14 and the sensing electrodes 11 to which they belong.

In some embodiments, the dummy patterns 13 and 14 may be arranged in the same size in regions symmetrical to each other around the intersection of the first and second sensing electrodes 11a and 11b. For example, the first and second dummy patterns 13a and 14a of the first sensing electrodes 11a are arranged in the same size in regions symmetrical to each other around the first connection patterns 12a. The first and second dummy patterns 13b and 14b of the 2 sensing electrodes 11b may be disposed in the same size in regions symmetrical to each other around the second connection patterns 12b.

Further, the dummy patterns 13 and 14 may have a shape bent to form an electrical movement path within the sensing electrodes 11. For example, the second dummy patterns 11b have second dummy patterns 14b at the edges of both sides, and the first dummy patterns bent in an L shape between the second dummy patterns 14b. (13b) may be located.

The shapes and positions of the dummy patterns 13 and 14 described above are exemplary, and the present invention is not limited thereto.

Meanwhile, the second sensing electrodes 11b may have protruding patterns 12c protruding toward the adjacent first sensing electrodes 11a and one end of the second connecting patterns 12b connected. The protruding patterns 12c prevent rapid inflow of static electricity into the second connection patterns 12b having a relatively narrow width, and electrically move the sensing electrodes 11 together with the dummy patterns 13 and 14 You can transform the path.

In some embodiments, a plurality of protruding patterns 12c may be provided on one sensing electrode, and the protruding patterns 12c are each sensing electrodes connected to each other between neighboring second sensing electrodes 11b. Can extend in opposite directions from each other.

In this embodiment, although the protruding patterns 12c are protruded from the second sensing electrodes 11b separated from each other and illustrated to be connected to the second connecting patterns 12b, as another embodiment, the first sensing electrodes Of course, when (11a) has a separate pattern, it may be protruded from the first sensing electrodes 11a and connected to the first connection patterns 12a.

Together with the dummy patterns 13 and 14 and the protruding patterns 12c, the touch screen panel of the present invention further includes a plurality of static electricity induction patterns 15 to prevent driving failure of the touch screen panel due to static electricity. The effect can be increased.

Referring to region B of FIG. 2 and FIG. 3B, the static electricity induction patterns 15 are electrically connected to any one of the first and second sensing electrodes 11a and 11b, and each of the sensing electrodes and its neighbors are connected to each other. It extends in the direction toward one sensing electrode and is formed so that some regions overlap with the adjacent sensing electrode.

Here, the first insulating film 30 is interposed between the static electricity induction patterns 15 and the sensing electrodes that are not electrically connected and overlap.

The electrostatic induction patterns 15 may be formed on the same layer with the same material as the second connection patterns 12b for simplifying the process. In addition, the static electricity induction patterns 15 may also be formed of a low-resistance opaque metal material, such as the second connection patterns 12b and the outer wirings 21.

In some embodiments, any one of the sensing electrodes 11 electrically connected to one end of the static electricity induction patterns 15 may be connected through direct contact. In this case, contact resistance may be determined according to the size of the contact area of one end of the static electricity induction patterns 15 and the sensing electrodes 11.

In another embodiment, the electrostatic induction patterns 15 are separated and patterned on the upper or lower layers of the sensing electrodes 11 to which they are connected, but one end is through a contact hole formed in the first insulating film 30 It can be electrically connected.

Thus, when static electricity is induced toward the static electricity induction patterns 15, stability may be secured to the first and second connection patterns 12a and 12b, and damage such as disconnection may be applied to the static electricity induction patterns 15. However, this does not affect the operation of the touch screen panel.

As described above, according to the present invention, the dummy patterns 13 and 14 are formed in some regions of the sensing electrodes 11 or the protruding patterns protruding from the sensing electrodes 11 and connected to the connecting patterns 12 By forming the fields 12c, by narrowing the width of the electrical movement path at the intersection of the sensing electrodes 11, the path is bypassed to buffer the rapid inflow of static electricity into the high resistance region, which is the intersection of the sensing electrodes 11 It can play a role. Accordingly, it is possible to improve the problem of driving failure of the touch screen panel due to static electricity.

Here, the dummy patterns 13 and 14 use the same material as the sensing electrodes 11, and thus have an advantageous side for securing visibility, and increase the size of the dummy patterns 13 and 14 to prevent static electricity. Can be improved.

Further, the electrostatic induction patterns 15 formed to be electrically connected to the sensing electrodes 11 and extending in a direction toward the neighboring sensing electrodes so that some regions overlap with the neighboring sensing electrodes are formed together, thereby touching by static electricity. The effect of preventing the driving failure of the screen panel may be increased.

4 and 5 are plan views illustrating a modified embodiment of the touch screen panel illustrated in FIG. 2. For the components having the same reference numbers as the aforementioned components, reference may be made to the above-mentioned disclosure unless contradictory, and duplicate description will be omitted.

Referring to FIG. 4, the touch screen panel of this embodiment protrudes from the first dummy patterns 113 without the second dummy patterns 14 and the static electricity induction patterns 15 among the patterns of the embodiment shown in FIG. 2. It shows that it consists of only the patterns 112c.

The first sensing electrodes 111a include a plurality of first dummy patterns 113a, and the second sensing electrodes 111b include a plurality of first dummy patterns 113b and protruding patterns 112c. Includes.

In some embodiments, the first dummy patterns 113b and the protruding patterns 112c may have a shape bent in an 'L' shape.

In another embodiment, the first dummy patterns 113b and the protruding patterns 112c may have a straight shape or a round shape curved in a curved shape, or may have a shape in which one or more of these shapes are combined.

The protruding patterns 112c may increase the length of the electrical movement path between the second sensing electrodes 111b.

Referring to FIG. 5, the touch screen panel of the present embodiment includes first dummy patterns 213 and second dummy patterns without protruding patterns 12c and static induction patterns 15 among the patterns of the embodiment illustrated in FIG. 2. It shows that it consists of only the fields 214.

The first sensing electrodes 211a include a plurality of first dummy patterns 213a, and the second sensing electrodes 211b are formed by a single second connection pattern 212b without a protruding pattern 12c. It is electrically connected, and includes first dummy patterns 213a and second dummy patterns 214, respectively. Here, the first connection patterns 212a and the second connection patterns 212b may be designed to be inclined in a diagonal direction.

As described above, the number, shape, and position of the dummy patterns, protrusion patterns, and static electricity induction patterns that buffer static electricity inflow can be variously combined and variously modified as necessary.

For example, as another embodiment of the present invention, the touch screen panel may be configured only with static electricity induction patterns and protrusion patterns without dummy patterns.

The touch screen panel according to the present invention directly forms touch sensing patterns such as the first and second sensing electrodes 11a and 11b and the first and second connection patterns 12a and 12b on the display panel. It can be usefully applied to a structure in which a panel and a display panel are integrated.

More specifically, the substrate 10 of the touch screen panel is set as the upper substrate of the display panel, and the first and second sensing electrodes 11a, 11b and the first and second connections are connected to one surface of the upper substrate of the display panel.

In this case, the first insulating layer 30 between the first and second connection patterns 12a and 12b may be provided. The thickness of the may be limited.

For example, when the display panel is set to an organic electroluminescent display panel or the like in which the upper and lower substrates are sealed by a frit, when the first insulating film 30 is formed as a thick organic insulating film, the organic insulating film is subjected to high temperature frit firing temperature. There is a possibility of breakage, and it can be replaced with an inorganic insulating film.

That is, when the substrate 10 serving as the base of the touch screen panel is set as the upper substrate of the display panel and the touch screen panel and the display panel are integrated and implemented, the first insulating film 30 includes first and second sensing electrodes. (11a, 11b) and the first and second connection patterns (12a, 12b) may be designed as an inorganic insulating film that is formed entirely on the formed touch active region. In the case of the inorganic insulating film, the thickness of the organic insulating film is reduced due to film stress. Is limited.

Therefore, the first insulating film 30 made of an inorganic insulating film may be vulnerable to static electricity due to its limited thickness, but as in the present invention, the protruding pattern 12c, dummy patterns 13, 14 and static electricity induction patterns When at least one of (15) or a combination thereof is formed, the static electricity vulnerability is improved, and the touch screen panel according to the present invention can be usefully applied to a structure integrated with a display panel.
