Description

Touch window and display device including the same {TOUCH WINDOW AND DISPLAY WITH THE SAME}

The present disclosure relates to a touch window and a display device including the same.

Recently, in various electronic products, a touch panel for inputting an image displayed on a display device by contacting an input device such as a finger or a stylus has been applied.

The touch panel may be typically classified into a resistive type touch panel and a capacitive type touch panel. When a pressure is applied to an input device, a resistive touch panel detects a change in resistance according to a connection between electrodes and detects a position. The capacitive touch panel detects a change in capacitance between electrodes when a finger touches it and detects a position. In consideration of the convenience and sensing power of the manufacturing method, the capacitive method has recently attracted attention in small models.

Meanwhile, in recent years, the demand for a bendable touch panel is increasing. That is, it is intended to expand the user's experience by bending or bending the touch panel. However, indium tin oxide (ITO), which is most widely used as a transparent electrode of a touch panel, is physically easily hit by the bending and bending of the substrate, so that the characteristics of the electrode deteriorate, thereby making a flexible device. There is a problem that it is not suitable for.

The embodiment provides a touch window with improved reliability and a display device including the same.

According to an embodiment, a touch window includes: a substrate including a first region sensing a touch and a second region disposed at an edge of the first region; A sensing electrode sensing a touch position in the first area; And a wiring connected to the sensing electrode, wherein the wiring includes a first wiring portion disposed in the first area and a second wiring portion disposed in the second area.

A display device according to an embodiment includes: a touch window; And a driving unit disposed on the touch window, wherein the touch window includes: a substrate including a first area for sensing a touch and a second area disposed at an edge of the first area; A sensing electrode sensing a touch position in the first area; And a wiring connected to the sensing electrode, wherein the wiring includes a first wiring portion disposed in the first area and a second wiring portion disposed in the second area.

In the embodiment, the wiring includes a conductive pattern, so that the pattern of the wiring is not visible on the screen area. That is, even if the wiring is formed of metal, the pattern can be made invisible. In addition, even when the wiring is applied to a large-sized touch window, resistance of the touch window can be reduced. In addition, when the wiring is formed by a printing process, a high-quality touch window can be secured by improving print quality.

In addition, conventionally, there has been a problem in that the wiring is disposed in a non-screen area, so that the bezel is widened. Accordingly, the screen area can be enlarged and a wider screen can be secured.

In addition, since both the sensing electrode and the wiring include a conductive pattern, the bending characteristics and reliability of the touch window may be improved.

Meanwhile, the sensing electrode of the touch window according to the embodiment may include a first sensing electrode and a second sensing electrode of a conductive pattern, and the first sensing electrode and the second sensing electrode may be disposed on the same plane. That is, since the first sensing electrode and the second sensing electrode are disposed on the same electrode substrate, the thickness of the touch window may be reduced and visibility may be improved. That is, when the first sensing electrode and the second sensing electrode are disposed on different electrode substrates, the thickness may increase, and when viewed from the top, the conductive pattern of the first sensing electrode and the conductive pattern of the second sensing electrode The moire phenomenon may occur while the patterns of are overlapped, but in the embodiment, by being disposed on one plane, this can be prevented.

In the description of the embodiments, each layer (film), region, pattern, or structure is “on” or “under/under” the substrate, each layer (film), region, pad or patterns. The description that "is formed in" includes both directly or through another layer. The criteria for the top/top or bottom/bottom of each layer will be described based on the drawings.

In the drawings, the thickness or size of each layer (film), region, pattern, or structure may be modified for clarity and convenience of description, so the actual size is not entirely reflected.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, a touch window according to an exemplary embodiment will be described in detail with reference to FIGS. 1 and 2. The touch window according to the embodiment may be a curved touch window or a flexible touch window.

The touch window according to the embodiment includes a cover substrate 130, a first electrode substrate 100, a sensing electrode 200 disposed on the first electrode substrate 100, a wiring 300, and the first electrode substrate ( 100) may include a second electrode substrate 110 disposed on the second electrode substrate 110, a sensing electrode 270 disposed on the second electrode substrate 110, a wiring 370, and the like.

The cover substrate 130 may be a curved cover substrate or a flexible cover substrate that can be bent.

The cover substrate 130 may include glass. Specifically, the cover substrate 130 includes chemically strengthened glass. The chemically strengthened glass includes chemically strengthened glass. For example, the chemically tempered glass may be so2A lime glass (Na2O?CaO?SiO2) or aluminosilicate glass (Na2O?Al2O3?SiO2).

Meanwhile, the cover substrate 130 may include a plastic film. Since the cover substrate 130 includes a film, the thickness of the touch window can be reduced.

The cover substrate 130 may have a certain strength so as to protect the sensing electrode 200 and the wiring 300.

The first electrode substrate 100 may be disposed under the cover substrate 130. An optical transparent adhesive 600 may be further included between the cover substrate 130 and the sensing electrode 100.

A sensing electrode 200 may be formed on the first electrode substrate 100. The sensing electrode 200 may detect whether an input device such as a finger is in contact.

The first electrode substrate 100 may include a first region 1A and a second region 2A.

The first area 1A means an area in which a user's touch command input is possible. That is, the first area 1A is an area for sensing a touch.

The second area 2A may be disposed outside the first area 1A. An external circuit connected to the wiring 300 may be located in the second region 2A. That is, the second area 2A is an area where the screen is not displayed because it is disposed at the edge of the screen area. In some cases, a touch may also be sensed in the second area 2A.

An outer dummy layer is disposed in the second area 2A. The outer dummy layer may be formed by coating a material having a predetermined color so that the wiring 300 and a printed circuit board connecting the wiring to an external circuit are not visible from the outside. The outer dummy layer may have a color suitable for a desired appearance, and for example, may include black pigment and the like to exhibit black. The outer dummy layer may be formed by deposition, printing, wet coating, or the like.

The sensing electrode 200 may be disposed in the first region 1A. The sensing electrode 200 may include a plurality of sensing units 201, 202, and 203. The plurality of sensing units 201, 202, and 203 may detect a location.

The sensing electrode 200 may include a first conductive pattern. For example, the sensing electrode 200 may be disposed in a mesh shape. In this case, the mesh shape may be randomly formed to prevent moire phenomenon. The moire phenomenon is a pattern created by overlapping periodic stripes. As neighboring stripes overlap, the thickness of the stripes becomes thicker, making them stand out compared to other stripes. Therefore, in order to prevent such moire phenomenon, the conductive pattern shape may be variously arranged.

Specifically, the sensing electrode 200 includes a conductive pattern opening OA and a conductive pattern line part LA. Conductive pattern lines 20 are disposed on the conductive pattern line part LA. In this case, the line width T1 of the conductive pattern line part LA may be 0.1 μm to 10 μm. The conductive pattern line portion LA having a line width T1 of 0.1 μm or less may not be possible due to a manufacturing process. When the line width T1 is 10 µm or less, the pattern of the sensing electrode 200 may be made invisible. Preferably, the line width T1 of the conductive pattern line part LA may be 1 µm to 10 µm.

Meanwhile, as shown in FIG. 2, the conductive pattern may have a regular shape. That is, the conductive pattern opening OA may have a rectangular shape. However, the embodiment is not limited thereto, and the conductive pattern opening OA may include various shapes such as a diamond shape, a pentagonal shape, a hexagonal polygon shape, or a circular shape.

In addition, the embodiment is not limited thereto, and the conductive pattern may have an irregular shape. That is, various conductive pattern openings may be provided in one conductive pattern. Accordingly, the sensing electrode 200 may include conductive pattern openings of various shapes.

Since the sensing electrode 200 has a mesh shape, the pattern of the sensing electrode 200 may not be seen on the first region 1A. That is, even if the sensing electrode 200 is formed of metal, the pattern may not be seen. In addition, even when the sensing electrode 200 is applied to a large-sized touch window, resistance of the touch window may be reduced. In addition, when the sensing electrode 200 is formed by a printing process, a high-quality touch window can be secured by improving print quality.

The sensing electrode 200 may include nanowires, carbon nanotubes (CNT), graphene, or various metals. In addition, the sensing electrode 200 may include Cu, Au, Ag, Al, Ti, Ni, or an alloy thereof. These materials have flexible properties that can be applied to bending and bending of a substrate.

A wiring 300 electrically connecting the sensing electrode 200 may be formed in the first region 1A and the second region 2A.

The wiring 300 may include a first wiring portion 301 disposed in the first area 1A and a second wiring portion 302 disposed in the second area 2A.

The line width of the first wiring portion 301 disposed in the first region 1A may be at least equal to or smaller than the line width of the second wiring portion 302. For example, a ratio of the width of the first wiring portion 301 and the width of the second wiring portion 302 may be 1:1 to 1:5. Through this, it is possible to make the first wiring part 301 invisible in the first region 1A. In addition, when the second wiring part 302 and the circuit board are connected, the contact area may be increased.

At least one of the first wiring portion 301 and the second wiring portion 302 may include a conductive pattern. For example, as shown in FIG. 2, the first wiring part 301 may include a conductive pattern. The first wiring part 301 may include a first conductive pattern. That is, the first wiring part 301 may include the same conductive pattern as the sensing electrode 200.

The wiring 300 includes a conductive pattern opening OA and a conductive pattern line part LA. Conductive pattern lines 31 are disposed on the conductive pattern line part LA. In this case, the line width of the conductive pattern line part LA may be 0.1 μm to 10 μm. The conductive pattern line portion LA having a line width of 0.1 μm or less may not be possible due to a manufacturing process. When the line width is 10 µm or less, the pattern of the wiring 300 may be made invisible. Preferably, the line width of the conductive pattern line part LA may be 1 µm to 10 µm.

Meanwhile, as shown in FIG. 2, the conductive pattern may have a regular shape. That is, the conductive pattern opening OA may have a rectangular shape. However, the embodiment is not limited thereto, and the conductive pattern opening OA may include various shapes such as a diamond shape, a pentagonal shape, a hexagonal polygon shape, or a circular shape.

In addition, the embodiment is not limited thereto, and the conductive pattern may have an irregular shape. That is, various conductive pattern openings may be provided in one conductive pattern. Accordingly, the wiring 300 may include conductive pattern openings of various shapes.

Since the first wiring portion 301 includes a dense conductive pattern, the pattern of the first wiring portion 301 may not be seen on the first region 1A. That is, even if the first wiring part 301 is formed of metal, the pattern can be made invisible. Also, even when the first wiring part 301 is applied to a large-sized touch window, resistance of the touch window may be lowered. In addition, when the first wiring part 301 is formed through a printing process, a high-quality touch window can be secured by improving print quality.

In addition, conventionally, there has been a problem that the wiring is disposed in the second area 2A, which is a non-screen area, so that the bezel is widened. You can reduce the size of the bezel. Accordingly, the screen area can be enlarged and a wider screen can be secured.

In addition, since both the sensing electrode 200 and the wiring 300 include a conductive pattern, bending characteristics and reliability of the touch window may be improved.

The wiring 300 may include the same material as or similar to the sensing electrode 200. The wiring 300 may include nanowires 222, carbon nanotubes (CNT), graphene, or various metals. In addition, the wiring 300 may include Cu, Au, Ag, Al, Ti, Ni, or an alloy thereof. These materials have flexible properties that can be applied to bending and bending of a substrate.

An electrode pad 400 is positioned at an end of the wiring 300. The electrode pad 400 may be connected to the printed circuit board 700. Specifically, although not shown in the drawings, a connection terminal is positioned on one surface of the printed circuit board 700, and the electrode pad 400 may be connected to the connection terminal. The electrode pad 400 may have a size corresponding to the connection terminal.

As the printed circuit board 700, various types of printed circuit boards may be applied. For example, a flexible printed circuit board (FPCB) may be applied.

Meanwhile, in FIG. 2, only the sensing electrode 200 and the wiring 300 disposed on the first electrode substrate 100 are illustrated and described, but the same or similar sensing electrode 270 on the second electrode substrate 110. ) And the wiring 370 may be disposed.

Each of the sensing electrode 200 disposed on the first electrode substrate 100 and the sensing electrode 270 disposed on the second electrode substrate 110 is a driving electrode for transmitting a signal and a receiving electrode for receiving a signal Can be

Hereinafter, a touch window according to another embodiment will be described with reference to FIG. 3. Referring to FIG. 3, the sensing electrode 200 and the wiring 300 may include a conductive pattern. In this case, the conductive pattern may be a pattern in which various types of curved and straight lines are mixed. Since the sensing electrode 200 and the wiring 300 are arranged in a mesh shape having a curved line, a moire phenomenon can be prevented. In addition, the moire phenomenon can be supplemented without an additional haze film through the embodiment. That is, the moire phenomenon can be prevented without increasing the thickness and losing the transmittance. Accordingly, the overall performance and reliability of the display can be improved.

Meanwhile, referring to FIGS. 4 and 5, in the touch window according to another exemplary embodiment, the second wiring unit 302 may also include a conductive pattern.

The first wiring portion 301 may include a first conductive pattern, and the second wiring portion 302 may include a second conductive pattern.

The line width T2 of the first conductive pattern 31 disposed in the first region 1A may be at least equal to or smaller than the line width T3 of the second conductive pattern 32. For example, a ratio of the line width T2 of the first conductive pattern and the line width T3 of the second conductive pattern may be 1:1 to 1:5. Through this, it is possible to make the first wiring part 301 invisible in the first region 1A. In addition, when the second wiring part 302 and the circuit board are connected, the contact area may be increased.

The width W2 of the first wiring portion 301 disposed in the first region 1A may be at least equal to or smaller than the width W3 of the second wiring portion 302. For example, a ratio of the width W2 of the first wiring portion 301 and the width W3 of the second wiring portion 302 may be 1:1 to 1:5. Through this, it is possible to make the first wiring part 301 invisible in the first region 1A. In addition, when the second wiring part 302 and the circuit board are connected, the contact area may be increased.

Meanwhile, referring to FIGS. 6 and 7, a dummy pattern 250 may be disposed adjacent to the first conductive pattern 20 in a touch window according to another exemplary embodiment.

The dummy pattern 250 may be disposed in the shorting portion 350. A pattern of the sensing electrode 200 may be formed through the shorting portion 350. Accordingly, the shorting portion 350 is disposed adjacent to the sensing electrode 200.

The distance D2 between the dummy pattern 250 and the first conductive pattern 20 may be larger than the line width T1 of the conductive pattern 20 and smaller than the distance D1 between the conductive patterns 20. . As an example, a distance D2 between the dummy pattern 250 and the first conductive pattern may be 1 μm to 500 μm.

In the embodiment, by including the dummy pattern 250, electrical characteristics of the sensing electrode 200 and visibility of the touch window may be improved. Accordingly, the reliability of the touch window can be improved.

Referring to FIG. 8, a plurality of wires 310 and 320 may be connected to a sensing unit of a touch window according to another embodiment. Specifically, the wires 310 and 320 may include a first connection wire 310 connected to one end of the sensing unit and a second connection wire 310 connected to the other end of the sensing unit. That is, the wirings 310 and 320 may be connected by double routing. Through this, it is possible to reduce the line resistance of the wires 310 and 320, thereby improving the efficiency of the touch window. Further, in the embodiment, since the wirings 310 and 320 are disposed in the first region 1A including a conductive pattern, they may be formed without an increase in the bezel.

Meanwhile, the first connection wiring 310 may be drawn out to the upper end of the first electrode substrate 100. The second connection wiring 320 may be drawn out to the lower end of the first electrode substrate 100. That is, the first connection wire 310 and the second connection wire 320 may be drawn in different directions. Accordingly, different printed circuit boards may be connected to the first connection wiring 310 and the second connection wiring 320, respectively. A first printed circuit board connected to the first connection line 310 and a second printed circuit board connected to the second connection line 320 may be further provided.

That is, since the first sensing electrode 210 and the second sensing electrode 220 are disposed on the same first electrode substrate 100, the thickness of the touch window can be reduced and visibility can be improved. That is, when the first sensing electrode 210 and the second sensing electrode 220 are disposed on different electrode substrates, the thickness may increase, and when viewed from the top, the conductive pattern of the first sensing electrode 210 The moire phenomenon may occur when the pattern of the conductive pattern of the second sensing electrode 220 is overlapped with each other, but in the embodiment, it is disposed on one plane to prevent this.

For example, the fourth sensing unit 221 may extend in a first direction, and the fifth sensing unit 222 may extend in a second direction crossing the first direction. The fifth sensing unit 222 may extend from the fourth sensing unit 221. In this case, the angle θ between the fourth sensing unit 221 and the fifth sensing unit 222 may be 90 degrees or less. Specifically, an angle θ between the fourth sensing unit 221 and the fifth sensing unit 222 may be 10 degrees to 90 degrees.

Meanwhile, the third sensing unit 223 extends from the fifth sensing unit 222 and may have a different orientation from the fifth sensing unit 222. The third sensing unit 223 may extend in the first direction. In this case, an angle between the fifth sensing unit 222 and the third sensing unit 223 may be 90 degrees or less. Specifically, an angle between the fifth sensing unit 222 and the third sensing unit 223 may be 10 degrees to 90 degrees.

While having such regularity, a plurality of sensing units may extend from the third sensing unit 223.
