## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims priority to and the benefit of Korean Patent Application No. 10-2010-0033267, filed on Apr. 12, 2010, in the Korean Intellectual Property Office, the entire content of which is incorporated herein by reference.
BACKGROUND
1. Field
Aspects of the present invention relate to a touch screen panel, and particularly a touch screen panel that is prevented from malfunction by static electricity.
2. Description of the Related Art
A touch screen panel is an input device selecting contents displayed on a screen, such as an image display device, or other similar electronic devices displaying an image, using a person's hand or an object to input commands of a user. For this reason, selected instructions at the touch positions are accepted as an input signal. To this end, the touch screen panel is provided on a front face of the image display device and converts the touch positions directly contacting a person's hand or an object into electrical signals.
The touch screen panel can replace a separate input device, such as a keyboard, a mouse or other similar devices, that are connected with the image display device and operated to input signals. Thus, the use of the touch screen panel is being increased. The touch screen panel can be a resistive type, a light sensing type, a capacitive type, or other similar types of touch screen panels.
When the person's hand or the object contacts the touch screen panel in the capacitive type at a touch position, the conductive sensing pattern senses a change in capacitance by other adjacent sensing patterns or ground electrode. The sensed change in capacitance converts the touch position into the input signal as electrical signals. In order to determine the touch position on the contacting surface, the sensing pattern is configured to include first sensing patterns connected in a first direction and second sensing patterns connected in a second direction.
Generally, the first connection patterns and the second connection patterns intersect with each other and there is an insulating layer disposed therebetween to insulate the first connection patterns and the second connection patterns from each other. A width of the first connection patterns and the second connection patterns is relatively narrower than a width of the pattern of the sensory cells. Thus a resistance of the first connection patterns and the second connection patterns is relatively large, and a thickness of the insulator insulating the first and second connection patterns from each other is thin because of a limit of a process to make the touch screen panel. Therefore, an intersection between the first and second connection patterns can be easily damaged by static electricity. When the intersection between the first and second connecting patterns is damaged by static electricity, for example, when a dielectric breakdown occurs, a malfunction of the touch screen panel can be caused.

In contrast, when an element is referred to as being disposed or formed “directly on” another element, there are no intervening elements present. Also, when an element, item or layer is referred to as being “connected to” another element, it can be directly connected or indirectly connected to another element, item or layer with one or more intervening elements, items or layers interposed therebetween. Hereinafter, like reference numerals refer to like elements. In contrast, when an element, item or layer is referred to as being “directly connected to” another element, item or layer there are no intervening elements, items or layers present.
FIG. 1 is a plan view showing a touch screen panel according to an embodiment of the present invention. Referring to FIG. 1, the touch screen panel includes a transparent substrate 10, sensory cells 12 and connection patterns 13 formed in a touch active region on the transparent substrate 10. Position detecting lines 15 are formed in a touch inactive region around the touch active region and connect the sensory cells 12 to an external driving circuit through a pad unit 20.
The sensory cells 12 include first sensory cells 12a connected with each other in a first direction in the touch active region on the transparent substrate 10. Also, the sensory cells 12 include second sensory cells 12b distributed between the first sensing cells 12a and connected with each other in a second direction intersecting with the first direction. The second sensory cells 12a do not overlap the first sensing cells 12a. 
In other words, the first sensory cells 12a and the second sensory cells 12b are alternatively spaced apart from each other and connected in different respective directions and are disposed in a same layer. For example, the first sensory cells 12a are respectively connected with the position detection lines 15 in each row so that they are connected in a row direction. The second sensory cells 12b are respectively connected with the position detection lines 15 in each column so that they are connected in a column direction. However, aspects of the present invention are not limited thereto, and the first sensory cells 12a and the second sensory cells 12b may be positioned in different layers. The first sensory cells 12a and the second sensory cells 12b are made of a transparent electrode material, such as ITO or other similar transparent materials, in order to transmit light from a display panel (not shown) disposed under the sensing cells.
The connection patterns 13 include first connection patterns 13a formed in the first direction and allowing the first sensory cells 12a to be connected in the first direction. The connection patterns 13 also include second connection patterns 13b formed in the second direction and allowing the second sensory cells 12b to be connected in the second direction. The connection patterns 13 are positioned in a same layer and are formed of the same materials as the first sensory cells 12a and the second sensory cells 12b. However, aspects of the present invention are not limited thereto, and the connection patterns 13 may be positioned in the different layers or made of different materials as or the first sensory cells 12a and the second sensory cells 12b. 
For example, the first connection patterns 13a are positioned in a layer above or under the layer having the first sensory cells 12a and the second sensory cells 12b. Also, the first connection patterns 13a may be formed of different materials from materials used to form the first sensory cells 12a and the second sensory cells 12b. For example, the first connection patterns 13a may be formed of materials used to form the position detection lines 15.
In this case, the first sensory cells 12a are separately patterned and have independent patterns, but are connected in the first direction by the first connection patterns 13a positioned in the different layers from the first sensory cells 12a. To achieve this, the first sensory cells 12a directly contact the first connection patterns 13a while at least partially overlapping the first connection patterns 13a, or may at least partially overlap the first connection patterns 13a. Insulating layers are disposed between the first sensory cells 12a and the first connection patterns 13a, and the first sensory cells 12a are connected to the first connection patterns 13a through contact holes formed in the insulating layers.
Additionally, at least some of the connection patterns 13 are positioned in a same layer as the first sensory cells 12a and the second sensory cells 12b. For example, the second connection patterns 13b are integrally connected with the second sensory cells 12b when a patterning of the second sensory cells 12b occurs. The first connection patterns 13a and the second connection patterns 13b are insulated from each other. To achieve this, the first connection patterns 13a and the second connection patterns 13b are alternatively disposed and the insulating layers are disposed therebetween.
However, aspects of the present invention are not limited thereto, and the first connection patterns 13a may allow the first sensory cells 12a to connect in the first direction without intersecting with the second connection patterns 13b. As such, the first connection patterns 13a are formed along a detour route overlapping the adjacent second sensory cells 12b. 
The position detection lines 15 are electrically connected with rows of the first sensory cells 12a and columns of the second sensory cells 12b. The position detecting lines 15 allow the first sensory cells 12a and the second sensory cells 12b to be connected with an external driving circuit, such as a position detection circuit, through the pad unit 20. The position detection lines 15 are positioned along an edge portion of the touch screen panel, and are not positioned in the touch active region displaying an image on the touch screen panel. The position detection lines 15 can be formed of a wide variety of materials, such as low-resistance materials, including Mo, Ag, Ti, Cu, Ti, Mo/Al/Mo, and other suitable materials, in addition to the transparent electrode materials used for forming the sensory cells 12.
The touch screen panel according to the present embodiment is a capacitive-typed touch screen panel. When the contact objects, such as human hand, stylus pen, and the like contact the touch screen panel, the change of the electrostatic capacitance at the contact position is transmitted from the sensory cells 12 to the drive circuit (not shown) through the pad unit 20 and the position detection lines 15. Then the contact position is confirmed by converting a value of the change of the electrostatic capacity into the electric signal through an X and Y input processing circuit (not shown).
FIG. 2 is a plan view showing connection patterns 13 and sensory cells 12 of a touch screen panel according to an embodiment of the present invention. FIG. 3 is a cross-sectional view taken along line I-I′ of FIG. 2. Referring to FIG. 2 and FIG. 3, the sensory cells 12 are disposed in a tessellating pattern. In other words, rows of the first sensory cells 12a are alternately disposed with rows of the second sensory cells 12b, and columns of the first sensory cells 12a are alternately disposed with columns of the second sensory cells 12b. 
The first sensory cells 12a are connected in the first direction by the first connection patterns 13a and the second sensory cells 12b are connected in the second direction by the second connection patterns 13b. In this case, the first direction and the second direction can be set in different directions intersecting with each other, and for example, the first direction and the second direction can be set in the row direction and the column direction, respectively. In other words, the first direction is approximately perpendicular to the second direction.
The second connection patterns 13b are positioned in the same layer as the sensory cells 12, thereby being patterned to integrally connected to the sensory cells 12b. 
The first connection patterns 13a are positioned in a different layer from a layer having the sensory cells 12 and the second connection patterns 13b. The first connection patterns 13a connect to the first sensory cells 12a via contact holes formed in the insulators 11. The sensory cells 12, according to the present embodiment of the present invention, include prominences 12a1, 12b1 extending toward adjacent ones of the sensing cells 12.
The prominences 12a1, 12b1 are formed at ends of respective first sensory cells 12a and second sensory cells 12b that are not connected with the connection patterns 13. For example, in the first sensory cells 12a, the prominences 12a1 are formed at the left and right ends of the first sensory cells 12a. The prominences 12a1 are not formed at the upper and the lower ends of the first sensory cells 12a, which are connected with the first connection patterns 13a. In the second sensory cells 12b, the prominences 12b1 are formed at the upper and lower ends of the second sensory cells 12b, and are not formed at the left and the right ends of the second sensory cells 12a, which are connected with the second connection patterns 13b. 
The prominences 12a1, 12b1 reduce a distance d between the adjacent sensing cells of the sensing cells 12. For example, the shortest distance d between adjacent ones of the sensing cells 12 is within the range from 2 μm to 6 μm. As such a distance between the adjacent ones of the sensing cells 12 that is a stable separation distance d provides proper driving of the touch screen panel and also the distance d easily induces a discharge of static electricity.
In other words, the distance d between the adjacent sensory cells is decreased by the prominences 12a1, 12b1, thus even if static electricity is present in the sensory cells 12, the discharge of the static electricity is induced through the prominences 12a1, 12b1. In a region susceptible to static electricity, i.e., the intersection between the first and the second connection patterns 13a, 13b, susceptibility to static electricity is improved by preventing dielectric breakdown. The dielectric breakdown is prevented because a voltage difference between the adjacent ones of the sensory cells 12 does not exist, or in other words, the adjacent ones of the sensory cells are in an isoelectric state. Specifically, the prominences 12a1, 12b1 may be formed to include at least one or more convexo-concave patterns at their ends to effectively induce the discharge of static electricity.
For example, as shown in the enlarged view of FIG. 2, the ends of the prominences 12a1, 12b1 are formed of the convexo-concave pattern and have a triangle shape formed at the sides of the prominences 12a1, 12b1. In this case, the distance d between the convexo-concave patterns formed at the prominences 12a1, 12b1 of the adjacent ones of the sensory cells 12 is within the range from 2 μm to 6 μm.
The sensory cells 12 are formed to include the prominences 12a1, 12b1 and extend toward the adjacent ones of the sensory cells 12. Thus, the prominences 12a1, 12b1 easily induce discharge of static electricity through the prominences 12a1, 12b1. Thus, damage to the sensory cells 12, resulting from dielectric breakdown generated by static electricity, can be prevented and a malfunction of the touch screen panel can be prevented.
FIG. 4 is a plan view showing connection patterns and sensory cells of a touch screen panel according to another embodiment of the present invention. FIG. 5 is a plan view showing connection patterns and sensory cells of a touch screen panel according to another embodiment of the present invention. In FIG. 4 and FIG. 5, the same or similar components as in FIG. 2 are designated by the same reference numerals, and a detailed description is not provided.
Referring to FIG. 4 and FIG. 5, shapes of the prominences 12a1, 12b1 are not limited to that as shown in FIG. 2, and may be modified in various shapes for inducing the discharge of static electricity. For example, as depicted in FIG. 4, the ends of the prominences 12a1′, 12b1′ have a rectangular convexo-concave patterns. In addition, as depicted in FIG. 5, the ends of the prominences 12a1′′, 12b1′′ have a saw-toothed convexo-concave patterns.
According to aspects of the present invention, static electricity is easily induced to discharge through the prominences 12a1′ 12a1′′, 12b1′, 12b1′′. Thus, damage to the sensory cells 12 and/or the touch screen panel, such as a dielectric breakdown generated by static electricity, can be prevented in advance, and a malfunction of the touch screen panel can be prevented.
Additionally, although not shown, a guard ring preventing static electricity may be disposed so as to surround the touch active region having the sensory cells 12. With the guard ring, it is possible to effectively discharge static electricity generated in the touch active region to the outside by reducing the distance between the guard ring and the prominences 12a1, 12a1′, 12a1′′, 12b1, 12b1′, 12b1′′ in the outermost sensing cells 12.
FIG. 6 is a plan view showing connection patterns and sensory cells of a touch screen panel according to another embodiment of the present invention. In FIG. 6, the same or similar components as in FIG. 2 are designated by the same reference numerals and a detailed description of the same or similar components is not provided. Referring to FIG. 6, dummy patterns 14 are further formed between the prominences 12a1, 12b1 of the sensing cells.
The dummy patterns 14 easily discharge static electricity generated in the touch active region. The dummy patterns 12 are positioned close to the prominences 12a1, 12b1 of the sensory cells. The shortest distance d between the prominences 12a1, 12b1 and the dummy pattern 14 adjacent to the prominences 12a1, 12b1 is within the range of 2 μm to 6 μm.
According to an embodiment of the present invention, the dummy patterns 14 are spaced apart from each other and are disposed in a same layer as the sensory cells 12. The dummy patterns are formed of same transparent electrode materials as the sensory cells 12. In the present embodiment, in patterning the sensory cells 12, the dummy patterns 14 are formed at the same time as the sensing cells, thereby easily performing the process. However, aspects of the present invention are not limited thereto, and the dummy patterns 14 may be formed of different materials from the sensory cells 12, such as materials for making the first connection patterns 13a or position detection lines (see 15 in FIG. 1). In addition, the dummy patterns 14 may be positioned in a different layer from the the layer having the sensory cells 12. For example, insulators may be disposed between the dummy patterns 14, and the dummy patterns 14 may be positioned on a layer above or below the sensory cells 12.
According to another embodiment of the present invention, the dummy patterns 14 are positioned in a different layer from the layer having the sensory cells 12, and an area of the dummy patterns 14 is increased. In the present embodiment, the dummy patterns 14 overlap the prominences 12a1, 12ba of the sensory cells. This embodiment will be described hereinafter with reference to FIG. 7 to FIG. 8B.
FIG. 7 is a plan view showing connection patterns and sensory cells of a touch screen panel according to another embodiment of the present invention. FIG. 8A and FIG. 8B are cross-sectional views showing examples of cross-sections taken along line II-II′ as depicted in FIG. 7. Referring to FIG. 7 to FIG. 8B, the dummy patterns 14′ are formed such that their ends overlap the prominences 12a1, 12b1 of the adjacent sensory cells. In the present embodiment, the dummy patterns 14′ are positioned in the different layers than the layers having the sensory cells 12. The insulating layers 11 are disposed between the dummy patterns 14′ and the sensory cells 12.
For example, as depicted in FIG. 8A, the dummy patterns 14′ are positioned under the prominences 12a1, 12b1 of the sensory cells to at least partially overlap the prominences 12a1, 12b1 of the sensory cells. Insulating layers 11 are disposed between the dummy patterns 14′ and the prominences 12a1, 12b1. According to another embodiment of the present invention, as depicted in FIG. 8B, the dummy patterns 14′ are positioned above the prominences 12a1, 12b1 of the sensory cells so as to at least partially overlap the prominences 12a1, 12b1 of the sensory cells. In the embodiment of FIG. 8B, insulating layers 16 are disposed between the dummy patterns 14′ and the prominences 12a1, 12b1. In both the embodiments shown in FIGS. 8A and 8B, the dummy patterns 14′ are positioned close to the prominences 12a1, 12ba of the sensory cells. A shortest distance d′ between the dummy patterns 14′ and the prominences 12a1, 12b1 of the sensory cells is within the range from 2 μm to 6 μm.
Meanwhile, in the embodiments of the present invention as mentioned above, the touch screen panel having a one layer structure on the sensory cells 12, i.e., the touch screen panel having the single-layered structure, in which the first sensory cells 12a and the second sensory cells 12b are positioned in the same layer were described. However, aspects of the present invention are not limited thereto. Aspects of the present invention can use a touch screen panel having a double-layered structure in which the first sensory cells 12a and the second sensory cells 12b are disposed in different layers. A detailed description of the double-layered structure will be described hereinafter with reference to FIG. 9 and FIG. 10.
FIG. 9 is a plan view showing connection patterns and sensory cells of a touch screen panel according to another embodiment of the present invention. And, FIG. 10 is a cross-sectional view showing an example of a cross-section taken along line III-III′ of FIG. 9. Referring to FIG. 9 and FIG. 10, the first sensing cells 12a and the second sensing cells 12b may be implemented in a double-layered structure in which they are alternatively disposed, with the insulating layers 11, in the sensing cells 12.
In this case, the first connection patterns 13a are integrally connected with the first sensory cells 12a, and the second connection patterns 13b are integrally connected with the second sensory cells 12b. In the touch screen panel according to the present embodiment, the prominences 12a1, 12ba of the sensory cells are formed to at least partially overlap the prominences 12a1, 12b1 of adjacent sensory cells 12, which are positioned in different layers.
In other words, the prominence 12a1 of the first sensory cells 12a are formed in the first layer to at least partially overlap the prominence 12b1 of the second sensory cells 12b, which are formed in the second layer and are adjacent to the first sensory cells 12a. In particular, ends of the prominences 12a1 overlap with ends of the prominences 12b1. The prominences 12a1, 12b1 of the adjacent sensing cells 12 are positioned close to each other to effectively induce the discharge of static electricity. The shortest distance d between the prominences 12a1, 12b1 of the adjacent sensing cells 12 positioned in different layers is set within the range from 2 μm to 6 μm.
According to aspects of the present invention, as described in the current embodiment, the first sensing cells 12a1 and the second sensing cells 12b1 are positioned in different layers, and the prominences 12a1, 12b1, respectively formed in the first sensing cells 12a and second sensing cells 12b, overlap with each other, at least partially. Thus, the first sensing cells 12a1 and the second sensing cells 12b1 effectively induce discharge of static electricity without having the dummy patterns 14 (see FIG. 6). However, aspects of the present invention are not limited thereto, and the touch screen panel having a double-layered structure could further include the dummy patterns 14.
The dummy patterns 14 may be positioned in a same layer as the first sensory cells 12a or the second sensory cells 12b. Alternatively, the dummy patterns may be positioned in a layer between a layer having the first sensory cells 12a and a layer having the second sensory cells 12b, or in a layer above or below the layers having the first sensory cells 12a and the second sensory cells 12b. In addition, the dummy patterns 14 may be formed without overlapping with the adjacent ones of the sensory cells 12 or may be formed to overlap with the prominences 12a1, 12b1 of the sensory cells 12.
Although a few embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in this embodiment without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
