That is, the integrated touch sensor according to the present invention is implemented in a structure including a plurality of sensor arrays constituting a polygonal unit sensing area S arranged at regular intervals, and a bridge electrode connecting each sensor array.

4 is a conceptual diagram enlarged by specifying one unit area as a partial area of the sensor electrode in FIG. 3. Hereinafter, the'unit sensing region S is defined as a cell in which a pair of capacitive electrodes are disposed and has a square structure.

That is, in a structure in which a plurality of sensor arrays are arranged, the unit sensing region S is defined as a square region, and the square region is a capacitance pattern including a sensor electrode pattern implemented in a region divided by a diagonal line. Pattern), and an electromagnetic resonance pattern (EMR pattern) comprising a linear electrode pattern disposed to be spaced apart from the capacitance pattern in a region adjacent to the unit sensing region S.

As shown in Figure 4, as shown in (a), the capacitance pattern (CAP pattern), Cap Tx patterns (X1, X2) arranged in a first direction (X-axis direction) and a second direction It may be composed of Cap Rx patterns (Y1, Y2) arranged in (Y-axis direction). That is, the unit sensing region S is a structure in which the Cap Tx patterns X1 and X2 arranged in the first direction (X-axis direction) are arranged in a structure in which triangular regions arranged left and right face each other, and the second direction ( It is a structure in which the triangular regions in which Cap Rx patterns (Y1, Y2) arranged in the Y-axis direction) are arranged vertically are opposed to each other.

The bridge electrode pattern BR is an electrode that interconnects the Cap Rx patterns Y1 and Y2, or connects the pattern of the neighboring unit cell region, as shown in FIG. 4B, to implement a sensor array. . Of course, the Cap Tx patterns (X1, X2) can be similarly connected by a bridge electrode to implement a sensor array.

FIG. 5 is a conceptual diagram illustrating a whole plurality of sensor arrays by expanding the unit cell region S described in FIG. 4.

Referring to FIG. 5, a pattern indicated by a sky blue outer line is a Cap Tx pattern, and a pattern indicated by a purple outer line is a Cap Rx pattern. The Cap Tx pattern and the Cap Rx pattern are implemented as a structure having one unit cell area, and the Cap Rx pattern is a triangular surface electrode pattern in electrode shape.

In addition, the pattern indicated by the orange outline is the vertical EMR pattern G2, and the pattern indicated by the blue is the horizontal EMR pattern G1.

The pattern indicated by the orange outline is a linear structure in the vertical direction (the second direction) in the vertical direction (second direction), and is spaced apart from the left and right of the unit cell area, and forms a loop that connects the pattern to the outside. In addition, the EMR horizontal pattern is a blue pattern, which is disposed above and below the unit cell area to form a loop in which the pattern is connected to the outer part.

The yellow electrode pattern is a bridge electrode pattern and serves to connect between Cap Tx patterns or connect Cap Rx patterns in a unit cell area.

Furthermore, the bridge electrode pattern performs a function of connecting vertical EMR patterns adjacent to each other.

For reference, the structure shown in FIG. 5 may be configured with the following specifications.

-Cell Size: 6mm x 6mm

-Cap Cell Size: 4.5mm x 4.5mm

-Channel resistance: Rx: 1 ~ 2Ω, Tx: 1 ~ 2Ω

In the case of a bridge pattern and an EMR pattern, it is composed of a line width of 0.1mm, and serves to connect the EMR pattern electrode and the cap pattern electrode.

-The gap between the Cap electrode pattern and the EMR electrode pattern is 0.33mm, and the gap between the EMR electrode pattern and the EMR electrode pattern is 0.65mm.

-In the case of the Cap Pattern (Tx, Rx), it is composed of a triangular-shaped area electrode pattern (not a fine pattern, but a metal pattern). This is a phenomenon that the overall resistance is lowered, and the channel resistance is formed to 1 ~ 2Ω.

A bouncing phenomenon occurs beyond the. When the pattern structure is implemented as an open structure, the magnetic field region is not confined but has a pattern that follows the electrode, so that the writing region (drawing region) extends to the region that follows the magnetic field, and the end of the touch pen Unnecessary bezel area (area where magnetic field is not confined and expanded) is recognized, and uniformity of touch performance cannot be secured.

Accordingly, the electromagnetic resonance pattern (EMR pattern) according to the present invention is preferably implemented as a closed loop loop in the EMR horizontal pattern or the EMR vertical pattern.

7 is an enlarged view of a unit cell region showing an embodiment of a structure different from that of FIG. 4.

The structure of the embodiment of FIG. 7 is a capacitance pattern (CAP pattern),

The basic structure consisting of Cap Tx patterns (X1, X2) arranged in the first direction (X-axis direction) and Cap Rx patterns (Y1, Y2) arranged in the second direction (Y-axis direction) is the structure of FIG. The same, but the difference in that the pattern electrode of the linear (Line type) rather than the shape of the Cap Tx pattern (X1, X2) or the Cap Rx pattern (Y1, Y2) is implemented in a zigzag form. There is. 'Zigzag type' means, as shown in FIG. 7, in each of the triangular regions of the Cap Tx patterns (X1, X2), the preceding electrode patterns whose horizontal length decreases toward the center of the unit sensing region (S) are sequentially arranged. There is a difference in that it is implemented as a structure that is bent as possible (hereinafter,'Z-shaped pattern structure'). The structure of this pattern makes it possible to increase the resistance within each channel, which has the advantage of implementing high touch accuracy.

Orange: EMR vertical pattern, Indigo: EMR horizontal pattern,

Yellow: Bridge Pattern

-Cell Size: 6mm x 6mm

-Cap Cell Size: 4.3mm x 4.3mm

-Cell internal Cap & EMR electrode line width: 0.1mm, spacing between patterns: 0.1mm

-The gap between Cap and EMR is 0.43mm, and the gap between EMR and EMR is 0.65mm.

-Channel resistance: Rx: 10.8 Ω, Tx: 15.6 Ω

-In the case of Cap Pattern, it is composed of a zigzag pattern (Z-shaped pattern). (Implemented as a line-type electrode to increase resistance than the example of FIG. 4, and the shape was designed in a Z-shaped pattern)

As can be seen from the above results, it can be seen that the channel resistance is increased by about 10 to 15 times compared to that of 1 to 2 Ω in the embodiment of FIG. 4. This indicates that the EMR sensing accuracy is greatly improved in the embodiment of FIG. 4.

Furthermore, as shown in FIGS. 8 and 9, the outermost loop interval: 13.73mm, the second outer loop interval: 17.9mm, the third outer loop interval: 18.65mm (All the same intervals from the third outer loop interval -> Basic channel loop gap: 18.65mm), the gap of the loop becomes narrower and more uniform than that of the embodiment of Fig. 4, so that the overall sensitivity of sensing can be increased. It was possible to confirm the difference in motion sensitivity from the outside. In particular, by implementing the end portion of the EMR pattern in a closed structure, it is possible to eliminate the sensing error from the outside of the touch note.
