1 is an exploded perspective view of a capacitive touch panel according to an embodiment of the present invention. Referring to FIG. 1, the cover 110, the first sensor electrode 120, the first wirings 121a and 121b, the second sensor electrode 122, the second wiring 123, and the third sensor electrode 124. 3, the third wiring 125, the circuit board 130, and the controller 140 are shown.

In this embodiment, in order to efficiently recognize the touched point, the sensor electrodes respectively recognizing the vertical and horizontal axes are alternately arranged, and the wiring can be simplified to minimize the border area, which is an inactive area. There is a characteristic. That is, referring to FIG. 1, the second sensor electrodes 122 and the third sensor electrodes 124 that recognize the position of the X axis are alternately arranged with the first sensor electrode 120 that recognizes the coordinates of the Y axis. Since each of the second wires 123 and the third wires 125 is connected in parallel, position signals generated therefrom may be obtained through the second wires 123 and the third wires 125. By such a configuration, the inactive area can be minimized.

In addition, the first sensor electrodes 120 that recognize the point on the Y-axis are individually connected to the plurality of first wires 121a and 121b so that each first sensor electrode 120 independently controls the signal on the Y-axis when touched. 140).

The cover 110 not only serves as a protective substrate for the touch panel according to the present embodiment but also allows capacitance to be formed between the touch means and each sensor electrode touched at a predetermined position. In this case, the touch means may be a user's body part (for example, a finger), a conductive rod, or a touch-only tool such as a stylus pen capable of conducting. In this case, the touch means a state in which the touch means can generate a predetermined signal for location recognition by capacitive coupling in proximity to the touch panel according to the present embodiment, and does not necessarily mean only physical contact.

Cover 110 may be a material having a predetermined dielectric constant, that is, a dielectric, and may be formed of any suitable material, such as chemically cured glass, plastic, acrylic, polyester, or other nonconductive material.

When the touch means touches the cover 110, capacitance is generated between the touch means and the first sensor electrode 120 to the third sensor electrode 124 by the following formula, and the controller 140 controls the touch means. The touch position can be detected by calculating the charge that flows through it.

(1)

(One)

Here, C is the capacitance, ε is the dielectric constant of the cover 110, A is the area where the touch means touches the cover 110, d is the thickness of the cover 110. When the user touches the touch means at a specific position on the screen, capacitance is formed between the contact surface and the first sensor electrodes 120 to the third sensor electrode 124 by the touch means, which is a conductor, and the charge according to the contact area is It exits through the touch means and the body. In this case, the controller 140 may charge the amount of the escaped charge and calculate the touch coordinates by calculating the amount of filling for each channel, which is an input signal.

The first sensor electrode 120 to the third sensor electrode 124 are arranged on the circuit board 130 and connected to the controller 140 by the first wirings 121a and 121b to the third wiring 125. . The first sensor electrode 120 has a rod shape, and the first sensor electrode 120 positioned upward in the Y axis is connected to the first wire 121b, and the first sensor electrode 120 positioned downward in the Y axis. ) Is connected to the first wiring 121a. The second sensor electrodes 122 are arranged one by one between the first sensor electrodes 120 and are connected to the controller 140 by the second wiring 123.

In addition, the third sensor electrodes 124 are arranged one by one between the first sensor electrodes 120, are meshed to correspond to the shape of the second sensor electrodes 122, and are connected to the third wiring 125. That is, the second sensor electrode 122 is a triangle having a bottom side in the upper direction of the X axis, and the third sensor electrode 124 has a bottom side in the lower direction of the X axis corresponding to the shape of the second sensor electrode 122. It is formed into a triangle. Accordingly, the second sensor electrode 122 and the third sensor electrode 124 have a rectangular shape as a whole in a state where the arrangement is completed by engaging with each other.

The first sensor electrode 120 extends in the first direction, that is, in the X-axis direction, and is connected to the controller 140 by separate first wires 121a and 121b, so that the controller 140 flows in charge. The generated first sensor electrode 120 may be identified to determine the Y coordinate of the touch position.

In addition, the controller 140 may determine the Y coordinate of the touch coordinate by measuring the intensity of the signal generated by the touch means. That is, when the touch means touches the cover 110, capacitances having different sizes are formed between the touch means and the immediately lower and adjacent first sensor electrodes 120, and the flow of charges is different. The controller 140 may determine the Y coordinate based on the first sensor electrode 120 having the largest amount of double charge filling. The Y coordinate may be determined in consideration of the position of each first sensor electrode 120. For example, when the amount of charge charged in the specific first sensor electrode 120 is twice as large as the amount of charge charged in the adjacent first sensor electrode 120, the specific first than the adjacent first sensor electrode 120 is determined. A position close to the sensor electrode 120 (for example, a position twice as close as that) can be determined by the Y coordinate. Such a Y coordinate may be determined by reflecting a linear proportionality or a proportional relationship by a preset formula to the amount of charged charge.

The second sensor electrode 122 and the third sensor electrode 124 extend in the first direction, that is, in the X-axis direction, and are in a second direction perpendicular to the X-axis direction, that is, Y, according to the extension length of the X-axis direction. The length in the axial direction is different. Therefore, when another point is touched according to the X-axis direction, an area of the second sensor electrode 122 and / or the third sensor electrode 124 corresponding to the touched point is changed to change the amount of current filling. The controller 140 may calculate the X filling amount of the current to obtain the X coordinate of the touch position. The relationship between the X coordinate and the amount of filling of the current, which is changed accordingly, may be stored in a lookup table in a storage unit (not shown) in advance and may be referred to when determining the coordinates of the touch position. In addition, the charge filling amount considerations of the adjacent sensor electrodes when determining the Y-axis coordinates described above may be applied to the X-axis coordinates.

The circuit board 130 may be formed of a transparent ITO film or ITO glass used in a touch panel or a semiconductor printed circuit board (PCB) that is generally used. The circuit board 130 is a substrate on which the sensor electrodes and wirings are formed. The area and thickness of the circuit board 130 may be determined by the size of the active region in which the sensor electrodes are located, the inactive region in which the wirings are located, and the method of forming the wiring. For example, when the wiring is formed using a via hole, unlike the illustrated example, the thickness of the circuit board 130 may be determined to a thickness at which the via hole may be efficiently formed.

In the present exemplary embodiment, since the first sensor electrode 120, the second sensor electrode 122, the second wiring 123, and the third sensor electrode 124 are alternately arranged with each other, the first sensor electrode 120, the second sensor electrode 122, and the third sensor electrode 124 are alternately arranged. Since it is possible to implement, the structure is simple and the design is convenient.

2 and 3 are partial electrode pattern diagrams of a capacitive touch panel according to an embodiment of the present invention. Hereinafter, in describing the electrode pattern diagram, the direction will be described with reference to the coordinate axis of FIG. 1 described above.

Referring to FIG. 2, a second sensor electrode 122, a second wiring 123, a third sensor electrode 124, and a third wiring 125 are illustrated. The bottom surface of the second sensor electrode 122 and the third sensor electrode 124 are opposite to each other, and the vertices of each triangle are formed to correspond to each other by extending to the bottom of each vertex facing each other. The second wiring 123 is connected to the bottom side of the second sensor electrode 122, and the third wiring 125 is connected to the bottom side of the third sensor electrode 124. The second sensor electrodes 122 are connected in parallel by the second wiring 123, and the third sensor electrodes 124 are connected in parallel by the third wiring 125. Accordingly, the second sensor electrodes 122 are connected to each other by one second wire 123, and the third sensor electrodes 124 are also connected to each other by one third wire 125. Since the resistance due to the wiring is almost negligible, the coordinates in the left and right directions (X axis direction) can be determined regardless of the up and down direction (Y axis direction) by the signal input as described above when the touch means is touched.

According to this embodiment, the capacitance value generated according to the position where the touch means is touched is generated at a different value according to the area of each sensor electrode, and the accurate position can be determined by comparing the position signals from both sensor electrodes. According to the present exemplary embodiment, since the second sensor electrode 122 and the third sensor electrode 124 are all tied to one circuit, the circuit simplification can be realized.

Referring to FIG. 3, a first sensor electrode 120 and first wirings 121a and 121b are shown. The first sensor electrodes 120 are individually connected to different first wires 121a and 121b. Therefore, a touch signal corresponding to the coordinates of the up and down direction (Y-axis direction) may be transmitted to the controller 140 when the touch means is touched. In addition, in order to minimize the size of the non-active area, the first wires 121a and 121b may be divided into a predetermined number and connected to the left and right directions of the first sensor electrode 120. That is, the first wiring 121a is connected to the right side of the first sensor electrode 120, and the first wiring 121b is connected to the left side of the first sensor electrode 120. The number of the first wiring 121a and the first wiring 121b may be substantially the same.

FIG. 4 is a first cross-sectional view of the capacitive touch panel according to the exemplary embodiment of FIG. 1 taken along the line of AA ′. Referring to FIG. 4, a cover 110, a first sensor electrode 120, a second sensor electrode 122, a third sensor electrode 124, and a circuit board 130 are shown.

This cross-sectional view is a cross-sectional view of an active region in which the sensor electrodes of FIG. 1 are located. The first sensor electrode 120, the second sensor electrode 122, and the third sensor electrode 124 are arranged to be spaced apart from each other at a predetermined interval. Squares indicated by dotted lines indicate one unit formed of the first sensor electrode 120, the second sensor electrode 122, and the third sensor electrode 124. When the touch means touches the cover 110 positioned at the top of the quadrangle, the touch means forms capacitance with each of the first sensor electrode 120, the second sensor electrode 122, and the third sensor electrode 124. As the charge filling amount occurs as described above, the coordinate value of the touch position may be determined.

Referring to FIG. 5, the cover 110, the first wiring 121b, the third wiring 125, the insulating layer 129, and the circuit board 130 are illustrated.

This cross section is a cross sectional view of an inactive region in which the wirings of FIG. 1 are arranged. The insulating layer 129 allows the first wiring 121b and the third wiring 125 to be insulated from each other, and is formed of a material that does not flow electricity. Since the first wiring 121b and the third wiring 125 are formed on different layers, the first wiring 121b and the third wiring 125 may be positioned on the same coordinate on the X axis of FIG. 1, thereby minimizing the inactive area. In addition, a structure in which the first wiring 121b and the third wiring 125 are formed on the same layer and can be insulated from each other is also applicable to the present invention.

In addition, according to another embodiment, the first sensor electrode 120 to the third sensor electrode 124 may be connected to each wire by a via hole (not shown). That is, a via hole connected to a portion of the first sensor electrode 120 to the third sensor electrode 124 may be formed in the circuit board 130 to connect each sensor electrode to the controller 140. According to this embodiment, there is an advantage that the inactive area where the above-described wirings are arranged can be minimized.

That is, as described above, the X-axis coordinates may be extracted using an area and a capacitance that vary as the X-axis coordinate values change. The second sensor electrode 622 extends in the first direction (X-axis direction) and is inclined to have a length in the second direction (Y-axis direction) perpendicular to the X-axis direction according to the extension length in the X-axis direction. The coordinates of the X-axis direction can be extracted.

As described above, the first sensor electrode 120 is arranged between the second sensor electrodes 622, and the second sensor electrodes 622 are connected to the same second wire 623. If the second sensor electrode 622 is inclined as described above, the lower side of the second sensor electrode 622 may be implemented in various shapes such as a taper shape, a right triangle, a vertical triangle, and the like, where the lower side is larger than the upper side.

According to the present embodiment, since the above-described third sensor electrode 124 and the third wiring 125 can be omitted, manufacturing cost and time can be saved, and an inactive area can be minimized. .

The areas engaged with each other depend on the length in the X-axis direction, and the charge filling amount described above is changed as the area is changed, so that the X coordinate of the touch position can be extracted. The second sensor electrode 722 may be coupled to each other in parallel by the second wiring 723 and the third sensor electrode 724 by the third wiring 725 to the controller 140.

Also, although the shape to be engaged, that is, the unevenness formed in the Y-axis direction is illustrated as a rectangle, it is not necessarily required to be a rectangle, for example, may be a shape such as a triangle or a rhombus.

In addition, according to another exemplary embodiment, the second sensor electrode 722 and the third sensor electrode 724 may not be engaged with each other, but may be formed symmetrically about a predetermined reference line.

In addition, the first sensor electrode 120 may be arranged corresponding to the shape of the second sensor electrode 722 and the third sensor electrode 724. That is, the second sensor electrode 722 and the third sensor electrode 724 have a trapezoidal shape, and the first sensor electrode 120 has an empty space formed by the second sensor electrode 722 and the third sensor electrode 724. It can be a shape having a protruding portion to fill the. Of course, the first sensor electrode 120 may have a rod shape as described above.
