1 is a block diagram schematically showing a block configuration of a touch sensing apparatus according to an embodiment of the present invention.

Referring to FIG. 1, a touch sensing apparatus 10 according to the present invention includes a driving electrode unit 200 including a plurality of driving electrodes 201 arranged in one direction, a plurality of driving electrodes 201, And a touch panel 11 including a sensing electrode unit 300 including a plurality of sensing electrodes 301 that are arranged in a row and a plurality of sensing cells 301. At the intersection of the driving electrode 201 and the sensing electrode 301, .

The mutual capacitance change sensed from the intersection (or sensing cell) of the driving unit 16a, the driving electrode 201 and the sensing electrode 301 that sequentially apply driving signals to the driving electrode 201 is detected A sensing unit 16b for generating a sensing signal corresponding thereto, and a position determining unit 16c for sensing a touch position by receiving a sensing signal from the sensing unit 16b.

2 is a cross-sectional view schematically showing a lamination structure of a touch sensing device according to an embodiment of the present invention.

1 and 2, the driving electrode unit 200 may be formed on the lower insulating substrate 100, and the sensing electrode unit 300 may be disposed on the upper insulating substrate 400. The sensing electrode unit 300 and the driving electrode unit 200 may be spaced apart from each other such that the sensing electrode unit 300 and the driving electrode unit 200 face each other.

The lower insulating substrate 100 may be made of polyimide (PI), polycarbonate (Pc), polyethylene terephthalate (PET), polyethersulfone (PES), polystyrene terephthalate (PEN), metal foil or fiber reinforced plastic A glass substrate, a quartz substrate, or the like may be applied.

Meanwhile, the upper insulating substrate 400 on which the sensing electrode unit 300 is formed may be a transparent window, and the sensing electrode unit 300 may be integrally formed on the transparent window. The transparent window serves to maintain the contour of the input portion of the touch screen panel and at least some of the regions may be exposed to the outside to accommodate contact input by a conductive object, such as the user's body or stylus. At this time, it is possible to selectively add a protective layer (not shown) to prevent damage or destruction of the transparent window due to the contact. The transparent window may be a thin glass, a plastic substrate, a glass substrate, a quartz substrate, or the like. The transparent window may be formed of a thin film glass, a polyimide (PI), a polycarbonate (Pc), a polyethylene terephthalate (PET), a polyethersulfone (PES) Foil, FRP (Fiber Reinforced Plastic), or the like.

The sensing electrode unit 300 may be integrally formed on one surface of the transparent window. In this case, the sensing electrode unit 300 is directly patterned on the transparent window and is connected to the wiring unit to manufacture the touch panel (11 of FIG. 1), so that the sensing electrode unit 300 is formed on a separate substrate, It is possible to omit the adhering process of adhering to the transparent window through the adhesive material, for example, the lamination process, thereby eliminating the defects that may occur in the adhering process and greatly improving the yield of the process. Therefore, the expression "integrally or integrally" throughout this specification means that the sensing electrode unit 300 is directly formed on one surface of the transparent window without mediating a separate adhesive substance such as OCA or the like.

That is, it means any method that does not include a step of adhering to a transparent window in its formation process. The formation of the sensing electrode unit 300 'directly' in the transparent window means that not only the sensing electrode unit 300 is directly patterned on one exposed surface of the transparent window, but also a separate layer such as a scattering- And the sensing electrode 300 is formed on the surface of the coated transparent window by the same method as described above.

In one embodiment, ITO coated glass coated on at least one surface of ITO can be applied to a touch panel (11 of FIG. 1) according to the present embodiment. In this case, the sensing electrode unit 300 may be formed by patterning ITO coated on the glass substrate. In this case, the glass substrate may be used as a transparent window. Accordingly, the yield of the manufacturing process of the touch panel (11 of FIG. 1) can be increased and the thickness of the touch panel (11 of FIG. 1) can be reduced.

That is, the first protrusions 231 and the second protrusions 251 facing each other along the first axis direction (or the Y axis direction) can be arranged to be meshed with each other in a physically separated state.

The shape of the first projecting portion 231 and the second projecting portion 251 is not limited as long as the first projecting portion 231 and the second projecting portion 251 can be arranged to be interlocked with each other. 13 and 14 illustrate that the first protrusion 231 and the second protrusion 251 have a triangular shape. However, the first protrusion 231 and the second protrusion 251 may be semicircular, rectangular, pentagonal, And may have various geometric shapes.

On the other hand, in the touch sensing apparatus according to the present invention shown in FIG. 17, one drive channel CH2 contributes to detection of the second contact T2 as well as the first contact T1.

That is, according to the present invention, there is an advantage that a contact sensing range contributed by one driving electrode in the same channel pitch is wider, thereby enabling more accurate contact sensing. Further, even if the pitch of the channel is wider than that of the conventional structure, more accurate detection performance can be realized, and a sensing performance similar to that of the conventional one can be realized with a driving electrode with a smaller number of channels. The driving electrode of 6 mm channel spacing implemented with another serrated driving electrode according to an embodiment of the present invention exhibits similar contact sensing performance as a driving electrode of 4.5 mm channel spacing in the conventional rectangular shape.

On the other hand, the maximum length of the projection in the Y-axis direction may be set to 20 to 50% of the width of the driving electrode in the Y-axis direction. 13 and 14, when the protrusions are formed on both sides of the driving electrode, the maximum length of the protrusions in the Y-axis direction is 20 to 40% of the width of the driving electrode in the Y-axis direction Can be set. On the other hand, when the protrusion is formed only on one side of the driving electrode, the maximum length of each protrusion in the Y-axis direction may be set to 30 to 50% of the width of the driving electrode in the Y- Further, the maximum length of the projecting portion in the Y-axis direction can be set to be 1/3 of the width of the driving electrode in the Y-axis direction. In this case, the number of channels is 1/3 Can be reduced.
