Description

Touch window {TOUCH WINDOW}

Embodiments relate to a touch window and a touch device.

[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.

Such a touch window can be largely divided into a resistive touch window and a capacitive touch window. In the resistive touch window, the glass and the electrode are short-circuited by the pressure of 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.

Resistive touch windows can degrade performance by repeated use and scratches can occur. As a result, there is a growing interest in a capacitive touch window having excellent durability and long life span.

Such a touch window may be formed in various types according to the position of the electrode. For example, electrodes may be formed only on one surface of the cover substrate, or on one surface of the cover substrate and one surface of the substrate.

In recent years, the structure of the sensing electrode has been complicated in order to improve the touch sensitivity or to form the sensing electrode in a single layer structure.

Depending on the complexity of the sensing electrode, the structure of the wiring electrode connecting the sensing electrode and the printed circuit board can also be complicated.

In addition, since a touch interface is also required for a large display, it is required to enlarge the touch window.

Accordingly, an unavoidable disconnection problem may occur in the process of forming wiring electrodes in a complicated or enlarged touch window. Such disconnection of the wiring electrode can lower the reliability of the touch window.

Further, when the disconnection of the wiring electrode is found in the manufacturing process, there is a problem that the touch window is discarded or an excessive cost is involved in restoration, so that the unit price of the touch window may rise.

The embodiment attempts to provide a touch window with improved reliability.

A touch window according to an embodiment includes a substrate; A sensing electrode disposed on the substrate; A printed circuit board disposed on the substrate; A wiring electrode connecting the sensing electrode and the printed circuit board; And a reinforcing electrode disposed on the wiring electrode.

In the touch window according to the embodiment, since the reinforcing electrode electrically connecting short-circuited wiring electrodes is disposed, reliability can be improved.

The reinforcing electrode according to the embodiment has an advantage in that the forming process is simple and the unit price of the touch window can be lowered.

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

1 and 2, the touch window 10 according to the embodiment may include a substrate 100, a sensing electrode 400, a wiring electrode 500, and a printed circuit board 600.

First, 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-tempered 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.

Further, 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.

In addition, the substrate 100 may be curved with a partially curved surface. That is, the substrate 100 may be partially flat and partially curved with a curved surface. In detail, the end of the substrate 100 may be bent or bent with a curved surface or a surface with a random curvature.

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

In addition, the substrate 100 may be a curved or bended substrate 100. 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 sensing electrode 400, the wiring electrode 500, and the printed circuit board 600 may be disposed on the substrate 100. That is, the substrate 100 may be a supporting substrate.

The substrate 100 may include a cover substrate. That is, the sensing electrode 400, the wiring electrode 500, and the printed circuit board 600 can be supported by the cover substrate. Alternatively, a separate cover substrate may be further disposed on the substrate 100. That is, the sensing electrode 400, the wiring electrode 500, and the printed circuit board 600 are supported by the substrate 100, and the substrate 100 and the cover substrate can be bonded (bonded) via the adhesive layer.

The effective area AA and the ineffective area UA may be defined on the substrate 100. [

In the effective area AA, the display may be displayed, and in the ineffective area UA disposed around the effective area AA, the display may not be displayed.

In addition, the position of the input device (e.g., a finger or the like) can be sensed in at least one of the valid area AA and the ineffective 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 ineffective area UA may be disposed on at least one side of the effective area AA. For example, as shown in FIG. 2, the ineffective area UA may be disposed at the top and both sides of the effective area AA. Alternatively, unlike FIG. 2, the ineffective area UA may be disposed in all directions of the effective area AA. Alternatively, the ineffective area UA may be disposed only at the upper and lower ends of the effective area AA.

A perimeter dummy layer (not shown) may be disposed in the non-effective area UA of the substrate 100. The outer dummy layer includes a wiring electrode 500 disposed on the ineffective area, a printed circuit board 600 connecting the wiring electrode 500 to an external circuit, and the like so that a material having a predetermined color Can be formed.

The outer dummy layer may have a color suitable for a desired appearance, such as a black or white pigment, for example black or white. Or various color films can be used to display various color colors such as red, blue, and the like.

A desired logo can be formed on the outer dummy layer by various methods. Such an outer dummy layer can be formed by vapor deposition, printing, wet coating or the like.

The outer dummy layer may be disposed in at least one layer. For example, the outer dummy layers can be arranged in one layer or in at least two layers with different widths.

The sensing electrode 400 may be disposed on the substrate 100. 2, the first sensing electrode 410 and / or the second sensing electrode 420 may be disposed on one surface of the substrate 100 and extend in different directions. In addition, the insulating material may be disposed on the front surface of the effective region of the cover substrate on which the sensing electrode 400 is disposed. Next, a hole H may be formed in a portion of the insulating material where the second sensing electrode 420 is disposed, and a bridge electrode covering the hole H may be disposed. Accordingly, the first sensing electrode 410 and the second sensing electrode 420 are disposed on the same surface of the cover substrate by the insulating material and the bridge electrode, and can be insulated from each other.

2, the sensing electrode 400 includes a first substrate 100 having a first sensing electrode 410 having a first direction and a second sensing electrode 420 having a second direction. The formed second substrate 100 may be configured to be spaced apart from each other. That is, either the first sensing electrode 410 or the second sensing electrode 420 may be disposed on the substrate 100.

The sensing electrode 400 may include a transparent conductive material so that electricity can flow without blocking the transmission of light. For example, the sensing electrode may include indium tin oxide, indium zinc oxide ), A metal oxide such as copper oxide, tin oxide, zinc oxide, and titanium oxide.

Alternatively, the sensing electrode 400 may comprise a nanowire, a photosensitive nanowire film, a carbon nanotube (CNT), a graphene, a conductive polymer, or a mixture thereof.

Alternatively, the sensing electrode 400 may comprise a variety of metals. For example, the sensing electrode is made of chromium (Cr), nickel (Ni), copper (Cu), aluminum (Al), silver (Ag), molybdenum (Mo). Gold (Au), titanium (Ti), and alloys thereof.

A wiring electrode 500 may be connected to the sensing electrode 400. In detail, the wiring electrode 500 may include a first wiring electrode 510 connected to the first sensing electrode 410 and / or a second wiring electrode 520 connected to the second sensing electrode 420 .

If only the first sensing electrode 410 is disposed on the substrate 100, only the first wiring electrode 510 may be disposed on the substrate 100. Alternatively, when only the second sensing electrode 420 is disposed on the substrate 100, only the second wiring electrode 520 may be disposed on the substrate 100.

The wiring electrode 500 may be disposed on the substrate 100. In detail, the wiring electrode 500 can be disposed in the ineffective area UA. In another aspect, the wiring electrode 500 may be disposed on the outer dummy layer. Alternatively, a part of the wiring electrode 500 may be disposed in the effective area AA, and the remainder may be disposed in the ineffective area UA.

When the wiring electrode 500 is disposed in the ineffective area UA, it may contain an opaque material. On the other hand, when at least a part of the wiring electrode 500 is disposed in the effective area AA, the wiring electrode 500 may include the same material as the sensing electrode 400 described above. That is, the wiring electrode 500 may include a transparent conductive material.

The width of the wiring electrode 500 may be 500 [mu] m to 5 [mu] m. If the width of the wiring electrode 500 exceeds 500 mu m, the non-effective area UA is occupied by an excessively wide area, and the bezel size of the touch window can be increased. If the width of the wiring electrode 500 is less than 1 μm, the process of the wiring electrode 500 is difficult, the electrical resistance is increased, and the short circuit defect is excessively generated during the forming process, thereby decreasing the reliability.

Hereinafter, the wiring electrode 500 according to the embodiment will be described in more detail with reference to FIGS. 3 to 5. FIG.

Referring to FIGS. 3 to 4, defects may occur in the wiring electrode 500. For example, a part of the wiring electrode 500 can be opened. A part of the wiring electrode 500 connecting the sensing electrode 400 and the printed circuit board 600 is broken and the wiring electrode 500a connected to the sensing electrode 400 is connected to the printed circuit board 600 The wiring electrodes 500b can be separated from each other.

Such a short circuit phenomenon of the wiring electrode 500 may be caused when some of the wiring electrodes 500 are not formed in the process of forming the wiring electrode 500 or a part of the formed wiring electrode 500 is peeled off. For example, when the wiring electrode 500 is formed through a patterning process, some of the wiring electrodes 500 may be uncoated or peeled off to cause defects, but the present invention is not limited thereto.

At this time, the short circuit phenomenon of the wiring electrode 500 may occur to the wiring electrodes 500 disposed in the certain region A. That is, when the one-wire electrode 500 is short-circuited, the adjacent wiring electrodes 500 may also be short-circuited. At this time, the lengths of the shorting intervals of the wiring electrodes 500 arranged in the predetermined area A may be different from each other.

Referring to FIG. 4 in which the area A is enlarged in FIG. 3, it can be seen that the length of the shorting section becomes longer toward the wiring electrode 500 disposed at the outer periphery of the wiring electrode 500 adjacent to the effective area AA.

When a short-circuit region occurs in the wiring electrode 500 as described above, a change in capacitance caused in the sensing electrode 400 can not be transferred to the printed circuit board 600, so that the touch window may not operate. That is, when a short circuit phenomenon occurs in the wiring electrode 500, the reliability of the touch window may be deteriorated.

Therefore, if a defect is found in the wiring electrode 500, the wiring electrode 500 can be restored by performing a step of peeling off all of the wiring electrode 500 and then re-depositing the same. However, the process of re-forming the entire wiring electrode 500 has a problem that the cost is excessively increased. That is, the process of re-forming the entire wiring electrode 500 without restoring only the short-circuited region in which the problem has occurred may require an excessively large number of steps such as the step of peeling off the wiring electrode 500 and the redeposition process. In addition, there is a problem that a short-circuit phenomenon of the wiring electrode 500 may occur in a region where a defect has again occurred in the process of re-forming the entire wiring electrode 500.

5 shows a partial area of the wiring electrode 500 according to the embodiment. 6 is a cross-sectional view taken along line A-A of Fig.

Referring to FIGS. 5 to 6, a reinforcing electrode 550 may be further disposed on the substrate 100. The reinforcing electrode 550 can electrically connect the short-circuited wiring electrode 500.

In detail, the reinforcing electrode 550 can be disposed on the wiring electrode 500. That is, the reinforcing electrode 550 can be disposed on the exposed substrate 100 due to the short-circuit region O between the wiring electrode 500 and the wiring electrode 500.

The reinforcing electrode 550 may include a metal layer and an adhesive layer. The metal layer of the reinforcing electrode 550 may be formed of a different material from the wiring electrode 500, but is not limited thereto. The reinforcing electrode 550 may be adhered to the wiring electrode 500 or the substrate 100 through the adhesive layer.

In detail, the reinforcing electrode 550 can be disposed so as to directly contact the upper surface T of the wiring electrode 500. At this time, the reinforcing electrode 550 may be disposed so as to directly contact the short-circuited side surface S of the wiring electrode 500 as well. As described above, when the reinforcing electrode 550 is arranged to cover both the side surface S of the short-circuited wiring electrode 500 and the top surface T adjacent to the side surface S, the reliability of the wiring electrode 500 can be improved There is an advantage that it can be restored.

7 is a cross-sectional view taken along the line A-A of Fig. 5 according to another embodiment.

Referring to FIG. 7, the reinforcing electrode 550 may be disposed on the wiring electrode 500. In detail, a portion 551 of the reinforcing electrode 550 may be disposed so as to be in direct contact with the upper surface T of the wiring electrode 500. The reinforcing electrode 550 may be disposed on the substrate 100 while contacting the upper surface T of the wiring electrode 500 and extending while being bent. At this time, a space R may be formed between the reinforcing electrode 550 and the short-circuited side S of the wiring electrode 500. Therefore, the reinforcing electrode 550 may not contact the short-circuited side surface S of the wiring electrode 500. [

A space R is formed between the bent portion of the wiring electrode 500 and the wiring electrode 500 due to the ductility of the metal tape in the process of forming the reinforcing electrode 550 using the metal tape, The reinforcing electrode 550 can be formed.

8 is a cross-sectional view taken along the line A-A of Fig. 5 according to another embodiment.

Referring to FIG. 8, the reinforcing electrode 550 may be disposed on the wiring electrode 500. In detail, the reinforcing electrode 550 can be disposed so as to directly contact the short-circuited side surface S of the wiring electrode 500. That is, the reinforcing electrode 550 may not be disposed on the upper surface T of the wiring electrode 500. At this time, the thickness of the reinforcing electrode 550 may be equal to or smaller than the thickness of the wiring electrode 500.

Such a reinforcing electrode 550 can reduce a step between the wiring electrode 500 and the reinforcing electrode 550 as compared with the above-described embodiment, thereby improving the reliability of the touch window.

The reinforcing electrode 550 is disposed on the shorting region O of the wiring electrode 500 and connected to the wiring electrode 500 connected to the sensing electrode 400 and the printed circuit board 600 The wiring electrode 500 can be electrically connected.

The width W2 of the reinforcing electrode 550 may be equal to or wider than the width W1 of the wiring electrode 500. [

That is, the width W2 of the reinforcing electrode 550 can be set in accordance with the width W1 of the wiring electrode 500. [

The width W2 of the reinforcing electrode 550 may be 1 to 1.4 times the width W1 of the wiring electrode 500 in detail. More specifically, the width W2 of the reinforcing electrode 550 may be 1 to 1.2 times the width W1 of the wiring electrode 500. [ More specifically, the width W2 of the reinforcing electrode 550 may be 1 to 1.1 times or less of the width W1 of the wiring electrode 500. [ If the width W2 of the reinforcing electrode 550 is wider than the width W1 of the wiring electrode 500 by 1.4 times or more, a short-circuit defect with the adjacent wiring electrode 500 may occur. When the width W2 of the reinforcing electrode 550 is narrower than the width of the wiring electrode 500, the electrical resistance may be increased and the short-circuited wiring electrodes 500 may be difficult to connect to each other, have.

For example, when the width W1 of the wiring electrode 500 is 50 mu m, the width W2 of the reinforcing electrode 550 can be 50 mu m to 70 mu m. In detail, the width W2 of the reinforcing electrode 550 may be wider than the width W1 of the wiring electrode 500 by 0 to 20 [mu] m. More specifically, the width W2 of the reinforcing electrode 550 may be wider than the width W1 of the wiring electrode 500 by 0 to 10 mu m. When the width W2 of the reinforcing electrode 550 is narrower than that of the wiring electrode 500, the electrical resistance may be increased and the short-circuited wiring electrodes 500 may be difficult to be connected, . If the width W2 of the reinforcing electrode 550 is wider than the width W1 of the wiring electrode 500 by 20 mu m or more, a short-circuit defect with the adjacent wiring electrode 500 may occur.

The reinforcing electrode 550 may be disposed in each of the plurality of wiring electrodes 500 included in a part of the wiring electrode 500 where the wire is broken. As described above, the lengths of the shorting regions O in the plurality of wiring electrodes 500 may be different from each other. Regardless, the lengths of the plurality of reinforcing electrodes 550 may all be the same.

The wiring electrode 500 disposed on the left side in FIG. 5 is defined as a first electrode 501 and the second electrode 502 and the third electrode 501 are formed in this order from the right side of the first electrode 501, (503) and a fourth electrode (504). The first to fourth electrodes 501, 502, 503, and 504 may have different lengths of the short-circuit region O. FIG. The first to fourth electrodes 501, 502, 503, and 504 may have first to fourth reinforcing electrodes 550 to 550, respectively. At this time, the lengths H2 of the first to fourth reinforcing electrodes 550 and 550 may be the same.

The first to fourth reinforcing electrodes 550 to 550 may be formed to have the same length H2 when formed by a single process. That is, the reinforcing electrode 550 can be formed on the wiring electrode 500 included in the region where the wiring electrode 500 is defective, so that the process of forming the reinforcing electrode 550 can be simplified. At this time, the length of the reinforcing electrode 550 may be longer than the shortest length O in the region where the defects are generated. 5, when the length H1 of the shorting region O of the fourth electrode 504 in the wiring electrode 500 is the longest, the length of the reinforcing electrode 550 is the length of the fourth electrode 504 May be longer than the length (H1) of the shorting area (O).

[ More specifically, the metal film M may be etched with a laser to form the metal film M so as to correspond to the width of the wiring electrode 500, thereby forming the reinforcing electrode 550.

The step of forming the reinforcing electrode 550 can be performed only in the region A where all the wiring electrodes 500 are short-circuited. Therefore, there is an advantage that the stripping, redeposition, and photolithography processes of the wiring electrode 500 can be omitted.
