Description

Touch window {TOUCH WINDOW}

An embodiment relates to a touch window.

[0002] In recent years, a touch window has been applied to input images in a manner of touching an input device such as a finger or a stylus to an image displayed on a display device in various electronic products.

The touch window is typically divided into a resistive touch window and a capacitive touch window. The resistance film type touch window detects the change of resistance according to the connection between the electrodes when the pressure is applied to the input device, and the position is detected. The capacitive touch window senses the change in capacitance between the electrodes when a finger touches them, and the position is detected. Considering the convenience of the manufacturing method and the sensing power, recently, in a small model, the electrostatic capacity method has attracted attention.

The touch window may include a sensing electrode on a substrate and a wiring electrode connected to the sensing electrode. The touch window may detect a change in capacitance when a region where the sensing electrode is disposed to detect a position.

At this time, the sensing electrodes and the wiring electrodes may be disposed on one surface of the substrate using one substrate, or may be disposed on one surface of each substrate using a plurality of substrates.

When the sensing electrodes and the wiring electrodes are disposed on one surface of the substrate using one substrate, the wiring electrodes can be drawn out in various directions. For example, the wiring electrodes can be arranged extending from the effective area to the non- .

At this time, when the wiring electrodes disposed on the effective area include a metal, wiring electrodes can be visually recognized from the outside.

Therefore, a touch window having a new structure capable of solving the above problems is required.

Embodiments provide a touch window having improved transmittance.

A touch window according to an embodiment includes: a substrate; A sensing electrode disposed on the substrate; And a wiring electrode connected to the sensing electrode, wherein the wiring electrode includes a plurality of sub-wiring electrodes spaced at a first pitch in a direction in which the wiring electrodes extend and a second pitch in a direction different from the first pitch, Wherein the first pitch is larger than the second pitch.

The touch window according to the embodiment can have an improved transmittance.

In detail, the wiring electrode is disposed on the effective region where the display is displayed, the sub-electrodes of the wiring electrode are formed in a mesh shape, and the pitch of the mesh opening is controlled, whereby the transmittance of the effective region can be improved.

In other words, the touch window according to the embodiment can have an improved transmittance by making the pitch of the mesh openings of the wiring electrode different from the pitch of one direction and the pitch of the other direction.

In the description of the embodiments, it is to be understood that each layer (film), area, pattern or structure may be referred to as being "on" or "under / under" Quot; includes all that is formed directly or through another layer. The criteria for top / bottom or bottom / bottom of each layer are described with reference to the drawings.

Also, when a part is referred to as being "connected" to another part, it includes not only a case of being "directly connected" but also a case of being "indirectly connected" with another member in between. Also, when an element is referred to as "comprising ", it means that it can include other elements, not excluding other elements unless specifically stated otherwise.

The thickness or the size of each layer (film), region, pattern or structure in the drawings may be modified for clarity and convenience of explanation, and thus does not entirely reflect the actual size.

Hereinafter, a touch window according to an embodiment will be described with reference to FIGS. 1 to 6. FIG.

Referring to FIG. 1, a touch window according to an embodiment may include a substrate 100, a sensing electrode 200, a wiring electrode 300, and a printed circuit board 400.

The substrate 100 may be rigid or flexible.

For example, the substrate 100 may comprise glass or plastic. In detail, the substrate 100 may include chemically reinforced / semi- toughened glass such as soda lime glass or aluminosilicate glass, or may include polyimide (PI), polyethylene terephthalate (PET) , Propylene glycol (PPG) polycarbonate (PC), or the like, or may include sapphire.

In addition, the substrate 100 may include an optically isotropic film. For example, the substrate 100 may include a cyclic olefin copolymer (COC), a cyclic olefin polymer (COP), a polycarbonate (PC), a light polymethyl methacrylate (PMMA), or the like.

Sapphire has excellent electrical properties such as dielectric constant, which not only greatly improves the speed of touch reaction but also can easily realize space touch such as hovering and is applicable as a cover substrate because of its high surface strength. Here, hovering means a technique of recognizing coordinates even at a small distance from the display.

Also, the substrate 100 may be curved with a partially curved surface. That is, the substrate 100 may have a flat surface in part, and may have a curved surface in part. In detail, the end of the substrate 100 may be curved with a curved surface, or may have a curved surface with a curvature.

In addition, the substrate 100 may be a flexible substrate having a flexible characteristic.

In addition, the substrate 100 may be a curved or a bended substrate. That is, the touch window including the substrate 100 may be formed to have a flexible, curved, or bent characteristic. Accordingly, the touch window according to the embodiment is easy to carry and can be changed into various designs.

The substrate 100 may include a cover substrate. Alternatively, a separate cover substrate may be further disposed on the substrate 100. Further, when a separate cover substrate is further disposed on the substrate 100, the substrate and the cover substrate may be laminated via an adhesive layer. Accordingly, since the cover substrate and the substrate can be separately formed, it can be advantageous in mass production of the touch window.

In the substrate 100, a valid region AA and a non-valid region UA may be defined.

The display may be displayed in the effective area AA and the display may not be displayed in the non-valid area UA disposed around the valid area AA.

In addition, the position of the input device (e.g., a finger or a stylus pen) can be sensed in at least one of the effective area AA and the non-valid area UA. When an input device such as a finger is brought into contact with such a touch window, a capacitance difference occurs at a portion where the input device is contacted, and a portion where such a difference occurs can be detected as the contact position.

The sensing electrode 200 may be disposed on the substrate 100. For example, the sensing electrode 200 may be disposed on an effective region of the substrate 100.

The sensing electrode 200 may include a first sensing electrode 210 and a second sensing electrode 220. The first sensing electrode 210 and the second sensing electrode 220 may be spaced apart from each other. For example, the first sensing electrode 210 and the second sensing electrode 220 may be spaced apart from each other by a predetermined distance so as not to contact each other.

The sensing electrodes of the first sensing electrode 210 and the second sensing electrode 220 may be connected to each other. Also, the sensing electrodes of the first sensing electrode 210 and the second sensing electrode 220 may be spaced apart from each other.

For example, referring to FIG. 1, the first sensing electrodes 210 may be spaced apart from each other. For example, the first sensing electrode 210 may include a plurality of sub first sensing electrodes, and the sub first sensing electrodes may be spaced apart from each other. Also, the second sensing electrode 220 may include a plurality of sub-second sensing electrodes, and the sub-second sensing electrodes may be connected to each other.

The first sensing electrode 210 and the second sensing electrode 220 may be disposed on the same side of the substrate 100. For example, the first sensing electrode 210 and the second sensing electrode 220 may be disposed in direct or indirect contact with the substrate 100. That is, the first sensing electrode 210 and the second sensing electrode 220 may be spaced apart from each other so that they do not contact each other on the same surface of the substrate 100.

At least one of the first sensing electrode 210 and the second sensing electrode 220 may include a transparent conductive material to allow electricity to flow without disturbing the transmission of light. For example, The electrode may be formed of a metal such as indium tin oxide, indium zinc oxide, copper oxide, tin oxide, zinc oxide, titanium oxide, Oxide. ≪ / RTI > Accordingly, when manufacturing a touch window in which flexible and / or bending is implemented, the degree of freedom can be improved.

Alternatively, at least one of the first sensing electrode 210 and the second sensing electrode 220 may be a nanowire, a photosensitive nanowire film, a carbon nanotube (CNT), a graphene, a conductive polymer, And mixtures thereof. Accordingly, when manufacturing a touch window in which flexible and / or bending is implemented, the degree of freedom can be improved.

When using such a nanowire or a nanocomposite such as a carbon nanotube (CNT), the nanocomposite may be made of black, and the color and reflectance can be controlled while securing the electric conductivity by controlling the content of the nano powder.

Alternatively, at least one of the first sensing electrode 210 and the second sensing electrode 220 may include various metals. For example, the sensing electrode 200 may be formed of one selected from the group consisting of Cr, Ni, Cu, Al, Ag, and Mo. Gold (Au), titanium (Ti), and alloys thereof. Accordingly, when manufacturing a touch window in which flexible and / or bending is implemented, the degree of freedom can be improved.

The sensing electrodes 200 may be arranged in a mesh shape. For example, at least one of the first sensing electrode 210 and the second sensing electrode 220 may be disposed in a mesh shape.

The sensing electrode 200 may include a plurality of sub-electrodes disposed to intersect with each other, and the sensing electrode 200 may be disposed in a mesh shape as a whole by the sub-electrodes.

Since the sensing electrode has a mesh shape, the pattern of the sensing electrode can be made invisible on the effective area AA. That is, even if the sensing electrode is formed of metal, the pattern can be made invisible. In addition, the resistance of the touch window can be lowered even when the sensing electrode is applied to a touch window of a large size.

Referring to FIG. 2, the sensing electrode may include a sensing electrode mesh line LA 'formed by a plurality of sub-electrodes crossing each other. In addition, the sensing electrode 200 may include a sensing electrode mesh opening OA 'between the sensing electrode mesh line LA'.

The line width of the sensing electrode mesh line LA 'may be about 0.1 μm to about 10 μm. The mesh line having a line width of the sensing electrode mesh line LA 'less than about 0.1 m may not be possible in the manufacturing process, and when the sensing electrode line LA' is more than about 10 m, the sensing electrode pattern may be visually recognized from the outside. Alternatively, the line width of the sensing electrode mesh line LA 'may be about 1 탆 to about 5 탆. Alternatively, the line width of the second mesh line LA2 may be about 1.5 mu m to about 3 mu m.

In addition, the thickness of the sensing electrode mesh line LA 'may be about 100 nm to about 500 nm. If the thickness of the sensing electrode mesh line LA 'is less than about 100 nm, the electrode resistance may increase and the electrical characteristics may deteriorate. If the sensing electrode mesh line LA' is greater than about 500 nm, the overall thickness of the touch window becomes thick, Can be degraded. Preferably, the sensing electrode mesh line LA 'may have a thickness of about 150 nm to about 200 nm. More preferably, the thickness of the sensing electrode mesh line LA 'may be about 180 nm to about 200 nm.

The wiring electrode 300 may be connected to the sensing electrode 200. The wiring electrode 300 may be disposed on the substrate 100. For example, the wiring electrode 300 may be disposed on at least one of the effective area AA of the substrate 100 and the non-valid area UA. For example, the wiring electrode 300 may be disposed on the effective area AA and the ineffective area UA of the substrate 100.

For example, one end of the wiring electrode 300 is connected to the sensing electrode 200 and the other end is connected to the printed circuit board 400 disposed on the ineffective area UA of the substrate 100 .

The wiring electrode 300 is connected to the sensing electrode 200 on the effective area UA of the substrate 100 and electrically connected to the printed circuit board 400 on the ineffective area AA of the substrate 100. [ As shown in FIG. That is, the wiring electrode 300 may extend in the effective region of the substrate 100 in the direction of the non-effective region.

Referring to FIGS. 2 and 3, the wiring electrode 300 may include a plurality of sub-wiring electrodes 351. In detail, the wiring electrode 300 may include a plurality of sub-wiring electrodes 351 arranged to cross each other. The plurality of sub-electrodes 351 intersect with each other to form one wiring electrode 300.

The wiring electrode 300 may have a first pitch P1 and a second pitch P2 by the plurality of sub-electrodes. That is, the wiring electrode 300 may have a first pitch P1 in the first direction and a second pitch P2 in the second direction by a plurality of sub-electrodes which are intersected with each other and are spaced apart from each other

In detail, the first direction may be a direction in which the wiring electrodes extend. The second direction may be a direction different from a direction in which the wiring electrodes extend. For example, the first direction and the second direction may be directions intersecting with each other. In one example, the first direction and the second direction may be perpendicular.

That is, the first pitch P1 may be a direction in which the wiring electrode 300 extends, and the second pitch P2 may be different from a direction in which the wiring electrode 300 extends.

The first pitch P1 and the second pitch P2 may have different sizes. In detail, the first pitch P1 and the second pitch P2 may have different lengths.

Preferably, the first pitch P1 may be larger than the second pitch P2. That is, the first pitch P1 may have a longer length than the second pitch P2.

The first pitch P1 may have a length of less than about 300 [mu] m. In detail, the first pitch P1 may have a size of 100 mu m to 300 mu m. More specifically, the first pitch P1 may have a size of 150 mu m to 250 mu m. More specifically, the first pitch P1 may have a size of 180 mu m to 220 mu m.

If the first pitch P1 has a size of less than about 100 mu m, the process may be difficult and migration may occur between the sub-electrodes, resulting in a short circuit, thereby decreasing reliability. When the first pitch P1 is less than about 300 mu m, the overall width of the wiring electrode is increased to widen the non-effective region, making it impossible to achieve miniaturization. The mesh pattern is visible from the outside, .

These embodiments are merely illustrative of the present invention in order to explain the present invention in more detail. Therefore, the present invention is not limited to these embodiments.

Example 1

A touch window was prepared by disposing the sensing electrodes on the effective region of the substrate and disposing the wiring electrodes on the effective region and the non-effective region so as to be connected to the sensing electrodes on the effective region and the printed circuit board on the non-effective region.

At this time, the wiring electrode included a plurality of sub-electrodes, the first pitch in the extending direction of the wiring electrodes was about 200 mu m, and the second pitch in the direction crossing the extending direction of the wiring electrodes was 100 mu m.

Example 2

A touch window was manufactured in the same manner as in Example 1, except that the first pitch of the wiring electrodes was about 250 탆 and the second pitch was 100 탆.

Example 3

A touch window was manufactured in the same manner as in Example 1, except that the first pitch of the wiring electrodes was about 290 탆 and the second pitch was 100 탆.

Comparative Example

A touch window was manufactured in the same manner as in Example 1, except that the first pitch of the wiring electrodes was about 100 탆 and the second pitch was 100 탆.

Then, the difference in transmittance between Examples 1 to 3 and Comparative Examples was compared. The relative values of Examples 1 to 3 were measured with the transmittance of the comparative example set to zero.

Transmittance Example 1 + 1% Example 2 + 1.2% Example 3 + 1.3% Comparative Example 0

Referring to Table 1, it can be seen that the transmittance of the touch windows of Examples 1 to 3 is improved as compared with the comparative example.

In other words, it can be seen that the wiring electrodes of Examples 1 to 3 have improved transmittance compared to the comparative example in which the pitches are the same, by making the pitches of the mesh openings different from each other.

In FIG. 2, the mesh openings of the wiring electrodes have a rectangular shape, and the mesh openings of the sensing electrodes have a square shape. However, the embodiment is not limited to this, And may have a rectangular mesh opening shape like the wiring electrode.

Accordingly, it is possible to have an improved transmittance even in the region where the sensing electrode is disposed.

FIGS. 7 to 9 are views for explaining an electrode forming process of the sensing electrode and / or the wiring electrode according to the embodiment.

7, the sensing electrode and / or the wiring electrode according to the embodiment includes a metal layer M disposed on a front surface of a substrate 100, and the metal layer M is etched in a mesh shape, Can be formed. For example, a metal layer M such as copper (Cu) is deposited on the entire surface of a substrate 100 such as poly (ethylene terephthalate) (PET), and the copper layer is etched to form an embossed mesh A copper metal mesh electrode can be formed.

8, the sensing electrode and / or the wiring electrode according to the embodiment may be formed by forming a resin layer R including a UV resin or a thermosetting resin layer on the substrate 100, ), A metal paste (MP) can be filled in the depressed pattern.

The metal paste 340 may be a metal paste containing at least one metal selected from the group consisting of Cr, Ni, Cu, Al, Ag, Mo, and alloys thereof. Accordingly, by filling the metal paste in the mesh-shaped intaglio pattern P and curing it, a mesh-shaped metal mesh electrode can be formed

9, the sensing electrode and / or the wiring electrode according to the embodiment may be formed by forming a resin layer R including a UV resin or a thermosetting resin layer on a substrate 100, ), A metal can be sputtered on the resin layer.

At this time, the bump pattern of the nanopattern and the micro pattern can be formed by imprinting a mold having an engraved pattern.

Subsequently, the metal layer (M) formed on the nano pattern (P1) and the micro pattern (P1) is etched to remove only the metal layer formed on the nano pattern, and only the metal layer formed on the micro pattern is left, An electrode can be formed.

At this time, when the metal layer is etched, a difference in etching rate may occur depending on the difference in bonding area between the nano pattern 211 and the micro pattern 212 and the metal layer. That is, since the area of the contact between the micropattern and the metal layer is larger than the area of contact between the nano pattern and the metal layer, the metal layer M formed on the micropattern is less etched, The metal layer remains and the metal layer formed on the nano pattern is etched and removed, so that a metal electrode of a micropatterned embossed mesh shape can be formed on the substrate 100.
