<First embodiment>

Referring to FIG. 3 , the touch type display device 100 according to the present embodiment may include a display panel 110 and a touch panel 200 .

In the display panel 110 , a plurality of pixel regions P are arranged in a matrix form in a first direction and a second direction that intersect each other in a display region for displaying an image. Here, for convenience of explanation, the first direction and the second direction are referred to as the X-axis direction and the Y-axis direction. applies to

For example, in the display panel 110 for displaying a color image, the plurality of pixel regions P may include R, G, and B pixel regions, and the R, G, and B pixel regions are arranged in the first direction. may be alternately and repeatedly arranged along the

In this case, the display panel 110 may include a first substrate 120 on which an array element for driving the pixel region P is formed, and a second substrate 130 as an opposite substrate facing the first substrate 120 . have.

The touch panel 200 corresponds to a configuration that provides a touch screen function to the display device 100 . To this end, the touch panel 200 is a touch element, and includes a plurality of first touch electrode wirings TL1 arranged in a first direction to correspond to the display area of the display panel 110 and a second direction. It may include a second touch electrode wiring TL2 extending along the . On the other hand, the touch panel 200 includes third and fourth substrates 210 and 220 disposed below and above the first and second touch electrode wirings TL1 and TL2, so as to be attached to the display surface of the display panel 110 . can be configured.

The arrangement structure of the first and second touch electrode wirings TL1 and TL2 will be described in more detail with reference to FIG. 4 .

The first touch electrode wiring TL1 includes a plurality of first touch electrodes TE1 disposed along the first direction, and the second touch electrode wiring TL2 includes a plurality of second touch electrodes disposed along the second direction. and an electrode TE2.

The first touch electrode TE1 and the second touch electrode TE2 are disposed on the same surface in the touch panel 200 and are separated from each other and spaced apart from each other. However, the present invention is not limited thereto.

The adjacent first and second touch electrodes TE1 and TE2 are spaced apart from each other to form a capacitor therebetween, and touch recognition is performed by detecting a change in capacitance of the capacitor.

In this case, the first touch electrodes TE1 disposed on each row line and constituting the first touch electrode wiring TL1 may be integrally connected. That is, the first touch electrodes TE1 may be configured to extend to cross between the adjacent second touch electrodes TE2 and be integrally connected through a connection part connecting the adjacent first touch electrodes TE1. have.

On the other hand, the second touch electrodes TE2 disposed on each column line and constituting the second touch electrode wiring TL2 may have a shape separated from each other and may be configured to be connected to each other using the connection pattern CP. That is, the second touch electrodes TE2 are separated from each other by the first touch electrode wiring TL1 (ie, the connection portion of the neighboring first touch electrodes TE1 ), and the neighboring second touch electrodes TE2 are separated from each other. They may be configured to be connected through a connection pattern CP, which is a jumping pattern. At this time, an insulating layer is disposed between the connection pattern CP and the second touch electrode TE2, and a contact hole CH connecting both ends of the connection pattern CP to the second touch electrode TE2 is formed in the insulating layer. Accordingly, the neighboring second touch electrodes TE2 may be connected through the connection pattern CP.

Meanwhile, in the present embodiment, the spaced area SA defined between the first and second touch electrodes TE1 and TE2 adjacent to each other is configured to have a bent shape along the longitudinal direction thereof. In this regard, it will be described in more detail with reference to FIG. 5, which is an enlarged view of area “A” of FIG. 4 .

The first and second touch electrodes TE1 and TE2 adjacent to each other face each other and have first and second opposite sides S1 and S2 that are spaced apart from each other. A separation area SA is formed between the first and second touch electrodes TE1 and TE2 as a boundary.

At this time, the longitudinal direction LD of the separation area SA is substantially a linear direction for measuring the length of the separation area SA, which corresponds to the long axis direction of the separation area SA. That is, the longitudinal direction LD of the separation area SA is defined as a straight line direction perpendicular to the arrangement direction of the first touch electrode TE1 and the second touch electrode TE2 positioned on both sides thereof. The longitudinal direction LD is a diagonal direction between the first and second directions, and may be approximately 45 degrees from the first and second directions.

Based on the longitudinal direction LD, the separation area SA is configured to have a shape bent at least once in one or both sides of the longitudinal direction LD. In other words, the separation area SA may be bent once in one side of the longitudinal direction LD, or may be bent alternately to both sides a plurality of times. That is, the separation area SA is bent one time toward the first touch electrode TE1 or the second touch electrode TE2 , or alternately a plurality of both sides of the first touch electrode TE1 or the second touch electrode TE2 . It may be formed in a curved shape.

In this embodiment, for convenience of explanation, a case in which the separation area SA is alternately bent to both sides four times is taken as an example.

As such, as the separation area SA is formed in a bent shape, a plurality of bending portions BN (ie, bent portions) in the form of alternately protruding from both sides in the longitudinal direction LD are formed in the separation area SA. and a plurality of partial regions in the form that are alternately bent and extended in opposite directions by the bent portion BN are constituted by the inclined region SS. Here, in the present embodiment, it is exemplified that four bent portions BN are configured. In this case, five inclined areas SS may be formed in the separation area SA.

Looking at the structure of the inclined region SS in more detail, the inclined regions SS adjacent to both sides of the bent portion BN as a boundary are configured to extend to opposite sides of the separation region SA in an inclined form. do. That is, the adjacent inclined areas SS are configured to extend while forming an inclination in opposite directions with respect to the longitudinal direction LD of the separation area SA.

In this regard, reference may be made to FIG. 6 , in FIG. 6 , for convenience of explanation, two inclined areas SS positioned adjacent to both sides of the bent portion BN are referred to as first and second inclined areas SS1 and SS2. .

At this time, the first inclined area SS1 located on one side of the bent portion BN is a first side direction example of both sides of the longitudinal direction LD based on the longitudinal direction LD of the separation area SA. For example, the second touch electrode TE2 is disposed to be inclined in a direction in which it is positioned. On the other hand, the second inclined area SS1 located on the other side of the bent portion BN is a second side direction example of both sides of the longitudinal direction LD with respect to the longitudinal direction LD of the separation area SA. For example, the first touch electrode TE1 is disposed to be inclined in a direction in which it is positioned.

In this form, the inclined areas SS configured in the separation area SA are alternately inclined to both sides based on the longitudinal direction LD of the separation area SA. Due to this arrangement, the spaced area SA between the first and second touch electrodes TE1 and TE2 facing each other and adjacent to each other has a shape alternately bent to both sides.

As such, as the separation area SA is configured to have a bent shape, the first and second touch electrodes TE1 and TE2 defining the separation area SA also have the same bent shape. That is, the opposite sides S1 and S2 of the first and second touch electrodes TE1 and TE2 have the same bent shape as the separation area SA.

As described above, in the present embodiment, by configuring the separation area SA in a bent shape, it is possible to improve the visibility problem of the touch electrode.

In this regard, in the related art, the spaced area between the adjacent first and second touch electrodes has a linear shape, so that the pixel area exposed through the spaced area periodically repeats the same pattern along the linear spaced area. There is a problem that the electrode is visually recognized.

As such, the conventional touch electrode visibility problem is a result of the spaced area having a linear shape, that is, the spaced area has a continuity of a form that is uniformly continuous in a specific direction, thereby causing a visibility problem due to this continuity.

On the other hand, according to the present embodiment, the separation area SA has a bent shape unlike the conventional one. Accordingly, the separation area SA of the present embodiment has discontinuity that is not uniformly continuous in a specific direction, thereby effectively improving the visibility problem caused by the conventional separation area continuity.

That is, since the separation area SA has a bent shape, the pixel area pattern exposed through the separation area SA appears non-periodically unlike the prior art, so that the touch electrode visibility problem can be improved.

In this regard, reference may be made further to FIG. 7 , which is a diagram illustrating a pixel area exposed through a separation area in the present embodiment.

In the conventional case, as shown in FIG. 2 , it can be seen that pixel areas of the same color appear periodically and repeatedly in the same pattern along linear spaced areas.

On the other hand, as shown in FIG. 7 , in the present embodiment, the pixel areas of the same color do not appear periodically and repeatedly in the same pattern along the bent spaced area SA, but rather different patterns appear non-periodically. can be found Accordingly, the problem of visibility of the touch electrode through the separation area SA can be improved.

Meanwhile, in the present embodiment, the separation area SA is preferably configured to have a width d equal to or less than the size of the pixel area. In this case, the size of the pixel region means the width of the minor axis of the pixel region.

In this regard, when the width d of the separation area SA is larger than the size of the pixel area, the entire pixel area is exposed through the separation area SA so that the pixel areas can be recognized as the same pattern. As such, when the width d of the separation area SA is made smaller than the pixel area size, it is possible to prevent the entire pixel area from being recognized as a pattern, thereby improving the visibility of the touch electrode.

In addition, the bending angle α of the separation area SA, that is, the inclination angle α of the inclined area SS, has a range of approximately 22.5±17.5 degrees (ie, 10 to 40 degrees) based on the longitudinal direction LD. It is preferable, and it is more preferable to have a range of 22.5±5 degrees (ie, 17.5-27.5 degrees) more preferably. In relation to this angle range, if the inclination angle α is reduced, the shape of the separation area SA becomes close to the conventional linear shape, and visibility will be reduced. And, when the inclination angle α is increased, the extending direction of the inclination area SS of the separation area SA becomes close to the arrangement direction of the pixel areas (ie, the first and second directions), so that the pixel areas periodically form the same and similar pattern. It is highly likely to be recognized as a In consideration of this point, the present inventors have confirmed that the above angle range is preferable for improving visibility through a number of experiments, and in this regard, refer to [Table 1] below.

[Table 1] shows the test results of the touch electrode visibility according to the relationship between the bending angle and the number of turns of the separation area, and the width of the separation area and the size of the pixel area.

The visibility level experiment in [Table 1] was conducted when the size of the pixel area was 30um, and the bending angle was the bending angle, that is, the inclination angle, based on the longitudinal direction of the separation area. This is the case in which the region has a linear shape. In addition, the visibility level may be measured from 0 to 5 as the visibility of the touch electrode increases as the value increases, and a level of 0-1 corresponds to an allowable level of visibility that is difficult to substantially recognize the touch electrode and is higher than this. is an unacceptable level that causes a visibility problem because touch electrodes can be recognized.

Looking at the results of Test 1-10, it can be confirmed that in Test 1-8, which is a case in which the separation area is implemented in a bent shape, as in this embodiment, the visibility level is excellent as 0 to 1, which is an acceptable level. On the other hand, in the case of Test 9-10, which is implemented as a linear spaced area as in the prior art, the visibility level is 1.5 to 2.0, which is an unacceptable level, and it can be confirmed that there is a problem.

And, in implementing the separation region in a bent shape as in the present embodiment, in the case of Test 1-6, which is a case where the bending angle is approximately 22.5 degrees, the visibility level is 0, which is very excellent, and the bending angle is approximately 10 It can be seen that even in the case of test 7-8, which is the case of the figure, the visibility level is 0-1, which is excellent. At this time, looking at the results of Tests 2 and 8, where the number of bends and the width of the separation area are the same, setting the bend angle around 22.5 degrees in Test 2 is more visible than when the bend angle is set around 10 degrees in Test 8. It is more excellent than this, and it can be seen that it is more preferable to improve the visibility to set the bending angle to around 22.5.

In addition, in implementing the separation region in a bent shape as in the present embodiment, in the case of Test 1-8, in which the width of the separation region is less than or equal to the size of the pixel region in the relationship between the width of the separation region and the size of the pixel region, the visibility level is 0 to 1, confirming that it is excellent. At this time, looking at the results of Test 7-8 in which the number of bends and the angle of bend are the same, as the width of the separation area increases, the visibility level increases. can

As described above, according to the present embodiment, the spaced area SA between the adjacent touch electrodes TE1 and TE2 is formed in a bent shape at least once.

Accordingly, the spaced area SA has a discontinuity whose shape is not uniformly continuous in a specific direction, that is, its longitudinal direction, thereby effectively improving the visibility problem caused by the continuous linear shape of the conventional spaced area. .

8 is a diagram illustrating a structure of a touch electrode disposed on a touch panel of a touch type display device according to a second embodiment of the present invention, and FIG. 8 shows a region corresponding to FIG. 5 .

The display device according to the second embodiment further includes the metric electrode as compared with the first embodiment, and other configurations are substantially the same. can do.

Referring to FIG. 8 , the touch panel 200 includes a first touch electrode wiring TL1 including a plurality of first touch electrodes TE1 disposed in a first direction, and a plurality of first touch electrode wirings TL1 disposed in a second direction. A second touch electrode wiring TL2 including the two touch electrodes TE2 is formed.

The first touch electrode TE1 and the second touch electrode TE2 are disposed on the same surface in the touch panel 200 and configured to be separated from each other and spaced apart from each other.

In this case, the first touch electrodes TE1 disposed on each row line and constituting the first touch electrode wiring TL1 may be integrally connected. That is, the first touch electrodes TE1 may be configured to extend to cross between the adjacent second touch electrodes TE2 and be integrally connected through a connection part connecting the adjacent first touch electrodes TE1. have.

On the other hand, the second touch electrodes TE2 disposed on each column line and constituting the second touch electrode wiring TL2 have a shape separated from each other and are configured to be connected to each other using a connection pattern (refer to CP of FIG. 4 ). can be

Meanwhile, in this embodiment, the spaced area SA defined between the first and second touch electrodes TE1 and TE2 adjacent to each other is configured to have a shape bent at least once in the longitudinal direction LD. do. At this time, the bending angle of the separation area SA, that is, the inclination angle of the inclined area SS, is preferably in the range of approximately 22.5±17.5 degrees (ie, 10 to 40 degrees) based on the longitudinal direction LD, and more More preferably, it has a range of 22.5±5 degrees (ie, 17.5-27.5 degrees).

Furthermore, in the present embodiment, in the spaced area SA between the first and second touch electrodes TE1 and TE2, the first and second touch electrodes TE1 and TE2 are separated from each other and electrically floating. A der metric electrode DE, which is a touch electrode, is disposed.

As described above, the structure of the touch electrode further including the metric electrode DE will be described in more detail with reference to FIG. 9 . FIG. 9 is an enlarged view of the spaced region of FIG. 8 and a peripheral portion thereof.

The first and second touch electrodes TE1 and TE2 adjacent to each other face each other and have first and second opposite sides S1 and S2 that are spaced apart from each other. A separation area SA is formed between the first and second touch electrodes TE1 and TE2 as a boundary.

The separation area SA is configured to have a shape bent at least once in the longitudinal direction LD. In this embodiment, for convenience of description, a case in which the separation area SA is alternately bent four times is taken as an example.

As described above, as the separation area SA has a bent shape, a plurality of bending portions BN in the form of alternately protruding to both sides in the longitudinal direction LD are formed in the separation area SA, and the bent portion A plurality of partial regions in the form that are alternately bent and extended in opposite directions by BN are configured to be inclined regions SS.

That is, the inclined region SS adjacent to the bent portion BN as a boundary is inclined in opposite directions with respect to the longitudinal direction LD of the separation region SA and extended while forming an inclination.

In the separation area SA configured as described above, the dermeter electrode DE extending in a bent shape at least once along the bent extension path of the separation area SA is disposed. That is, the metric electrode DE has the same bent shape as that of the separation area SA where the teeth are disposed.

The dummy value electrode DE may include a plurality of dummy patterns DP separated from each other in the separation area SA, but is not limited thereto. That is, the metric electrode DE disposed in the separation area SA may be integrally formed.

As such, when the dummy value electrode DE is formed of the separated dummy pattern DP, the separated dummy pattern DP may be configured to be disposed in the corresponding inclined region SS. That is, the dummy patterns DP adjacent to each other may be configured to be separated by the bent portion BN of the separation area SA as a boundary.

Meanwhile, the metric electrode DE may not be formed on the edge of at least one end of the separation area SA. In this regard, for example, it may be configured such that the dummy electrode DE is not disposed in the inclined area SS located at one end of the separation area SA.

In addition, as the metric electrode DE is configured in the separation area SA, the width of the portion of the separation area SA in which the metric electrode DE is disposed, that is, the second width d2 is equal to that of the metric electrode DE. It becomes larger than the first width d1, which is the width of the edge of the spaced area SA where it is not arranged. In addition, the separation area SA2 defined between the metric electrode DE and each of the touch electrodes TE1 and TE2 has a shape that is bent at least once in the same way as the metric electrode DE. Here, for convenience of description, the separation area SA defined between the first and second touch electrodes TE1 and TE2 is referred to as the first separation area SA1, and is located inside the first separation area SA1. A separation area SA2 defined between the metric electrode DE and the touch electrodes TE1 and TE2 is referred to as a second separation area SA2.

Here, it is preferable that the first width d1 of the first spacing area SA1 is less than or equal to the size of the pixel area. In addition, as the width of the second spaced area SA2, the distance d3 between the metric electrode DE and the first and second touch electrodes TE1 and TE2 adjacent thereto is less than or equal to the first width d1, that is, the pixel area. It is preferable to make the size smaller than the first width d1, and it is more preferable to make it smaller than the first width d1.

As described above, in the present embodiment, the dermeter value electrode DE bent in the same shape as this is disposed in the first separation area SA of the bent shape. Accordingly, it is possible to further improve the visibility problem of the touch electrode.

That is, similarly as described in the first embodiment above, as the first and second spaced areas SA1 and SA2 defined between the touch electrodes are configured in a bent shape, the spaced areas SA1 and SA2 are formed in a specific direction. By having the discontinuity that is not uniformly continuous, it is possible to effectively improve the visibility problem caused by the continuity of the conventional linear spaced region.

Furthermore, in the present embodiment, the dummy value electrode DE having the same shape as the same as the above is disposed in the first spacing area SA1. The portion occupied by the dummy touch electrode DE acts as a non-exposed area covering the pixel area like the first and second touch electrodes TE1 and TE2, so that the exposed portion of the pixel area through the first separation area SA is can be reduced.

In this regard, the metric electrode DE is a touch electrode in a floating state, and it is possible to minimize the separation distance d3 between the metric electrode DE and the first and second touch electrodes TE1 and TE2 adjacent thereto. . That is, the separation distance d3 between the metric electrode DE and the first and second touch electrodes TE1 and TE2 adjacent thereto is, The spacing distance d1 between TE1 and TE2 may be configured to be smaller than the first width d1, which is the shortest width of the first spacing area SA1. Accordingly, exposure of the pixel area through the second spaced area SA2 between the dummy touch electrode DE and the first and second touch electrodes TE1 and TE2 can be minimized.

As such, when the metric electrode DE is further disposed, the region is between the adjacent touch electrodes, that is, the region between the metric electrode DE and the first touch electrode TE1 and the second touch electrode TE2. The exposure area for the pixel area can be reduced, and as a result, it is possible to further improve the visibility problem of the touch electrode due to the exposure of the pixel area.

In the above-described embodiments, an on-cell structure in which a touch electrode, which is a touch element, is disposed on a display surface of a display panel in the form of a panel has been described as an example, but is not limited thereto. For example, in an in-cell structure, the touch electrode may be configured to be disposed in the display panel.

The above-described embodiment of the present invention is an example of the present invention, and free modifications are possible within the scope included in the spirit of the present invention. Accordingly, the present invention includes modifications of the present invention provided they come within the scope of the appended claims and their equivalents.
