Description

Touch window {TOUCH WINDOW}

An embodiment relates to a touch window.

2. Description of the Related Art In recent years, a touch panel has been applied to an image displayed on a display device in various electronic products by a method of touching an input device such as a finger or a stylus.

Such a touch panel can largely be divided into a resistance film type touch panel and a capacitive type touch panel. In the resistive touch panel, the glass and the electrode are short-circuited by the pressure of the input device and the position is detected. A capacitance type touch panel senses a change in electrostatic capacitance between electrodes when a finger touches them, thereby detecting the position.

Meanwhile, the touch panel can be manufactured by laminating and bonding substrates on which electrodes are formed.

In this case, the different substrates must be formed at regular intervals in consideration of the interference of the electrodes. However, there is a problem that the electrodes formed on the substrates are not aligned with each other due to the tolerance in the bonding process.

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

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

A touch window according to an embodiment includes a first substrate; A first alignment portion formed on the first substrate; A second substrate; And a second alignment portion formed on the second substrate, wherein the first alignment portion and the second alignment portion are overlapped with each other, and the shapes of the first alignment portion and the second alignment portion are different from each other different.

The touch window according to an embodiment includes an alignment portion formed on different substrates.

A first alignment portion may be formed on the first substrate, a second alignment portion may be formed on the second substrate, and the first alignment portion and the second alignment portion may be overlapped with each other. The second alignment portion may include a scale. Accordingly, the first alignment portion is disposed on the basis of the second alignment portion, and it is possible to prevent the electrodes from being displaced from each other due to the tolerance.

That is, conventionally, the alignment marks are formed with the same shape. Accordingly, when laminating different substrates, the positions of the alignment marks are entirely shifted from each other, and the sensing electrodes formed on the substrates as a whole can also be arranged to be shifted. Further, in order to confirm the position of the alignment mark, a procedure of confirming the alignment with a separate microscope after the alignment process was required.

The touch window according to the embodiment can grasp the occurrence of the alignment errors and the quantitative values of the alignment errors formed in the different layers during the process as the second alignment portion includes the scale.

Accordingly, the reliability of the touch window and the process efficiency can be improved. Also, the process cost can be reduced.

In the case where at least one of the first substrate 100 and the second substrate 110 includes an optically isotropic film, the optical uniformity may be excellent. For example, at least one of the first substrate 100 and the second substrate 110 may be formed of a material selected from the group consisting of COC (Cyclic Olefin Copolymer), COP (Cyclic Olefin Polymer), light polycarbonate (PC) Polymethylmethacrylate (PMMA), and the like.

Sapphire has excellent electrical properties such as dielectric constant and can dramatically increase the speed of touch reaction. It can easily realize spatial 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, at least one substrate of the first substrate 100 and the second substrate 110 may be curved while partially having a curved surface. That is, at least one of the first substrate 100 and the second substrate 110 may have a flat surface, and may have a curved surface partially. In detail, at least one substrate of the first substrate 100 and the second substrate 110 may have a curved surface or a curved surface with a curved surface, which may be curved or curved. Accordingly, the convenience of the user can be improved due to the ergonomic design. For example, a touch device including at least one of the first substrate 100 and the second substrate 110 may have improved grip. For example, the touch device including the substrate of at least one of the first substrate 100 and the second substrate 110 may have an improved viewing angle.

Accordingly, the touch window according to the embodiment is easy to carry and can be changed into various designs.

The first substrate 100 and the second substrate 110 may be disposed on separate cover substrates. That is, the cover substrate may support the first substrate 100 and the second substrate 110. For example, the first substrate 100 may be disposed on the cover substrate, and the second substrate 110 may be disposed on the first substrate 100. In detail, the cover substrate, the first substrate 100, and the second substrate 110 may be sequentially stacked.

The cover substrate, the first substrate 100, and the second substrate 110 may be laminated or bonded together through an adhesive layer. Thus, the cover substrate and the substrate can be formed separately, which is advantageous for mass production of the touch window.

Alternatively, the first substrate 100 may be a cover substrate. That is, the first substrate 100 may support the second substrate 110. For example, the second substrate 110 may be disposed on the first substrate 100.

For example, the thickness of one of the first substrate 100 and the second substrate 110 may be 0.1 mm to 0.7 mm. For example, the thickness of one of the first substrate 100 and the second substrate 110 may be about 0.30 mm to about 0.5 mm.

If the thickness of one of the first substrate 100 and the second substrate 110 exceeds about 1 mm, the thickness of the touch window may increase. If the thickness of one of the first substrate 100 and the second substrate 110 is less than about 0.05 mm, the strength of the touch window may be lowered.

A valid region AA and a non-valid region UA may be defined on the first substrate 100 and the second substrate 110.

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

Also, at least one of the effective area AA and the ineffective area UA may sense the position of an input device (e.g., a finger, a stylus pen, etc.). When an input device such as a finger or a stylus pen 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 outer dummy layer may have a color suitable for a desired appearance, and may include 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.

When the outer dummy layer is disposed as a film, it can be easily arranged when the outer dummy layer is arranged on a curved surface or a flexible cover substrate.

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.

Electrodes may be disposed on the first substrate 100 and the second substrate 110.

For example, the second sensing electrode 220 may be disposed in at least one of the effective area AA and the non-valid area UA of the second substrate 110. In detail, the second sensing electrode 220 may be disposed on the effective area AA of the first substrate 100.

The sensing electrode 200 may include a conductive material. For example, the sensing electrode 200 may include a transparent conductive material so that electricity can flow without disturbing the transmission of light. For example, indium tin oxide, indium zinc oxide, copper oxide, tin oxide, zinc oxide, titanium oxide, and the like can be used. Of a metal oxide. As a result, the degree of freedom of pattern formation can be improved by using a transparent material.

Alternatively, the sensing electrode 200 may include a nanowire, a photosensitive nanowire film, a carbon nanotube (CNT), a graphene, a conductive polymer, or a mixture thereof. This increases the degree of freedom in creating a flexible and bendable touch window.

When nanocomposites such as nanowires or carbon nanotubes (CNTs) are used, they may be made of black. The color and reflectance can be controlled while securing the electric conductivity by controlling the content of the nano powder.

Alternatively, the sensing electrode 200 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, Mo, Au, ), And alloys thereof. This increases the degree of freedom in creating a flexible and bending touch window. For example, the sensing electrode 200 may be formed in various patterns as it includes a metal.

The line width of the mesh line may be about 0.1 탆 to about 10 탆. The mesh line portion having a line width of the mesh line less than about 0.1 mu m may be impossible in a manufacturing process or short-circuiting of a mesh line may occur. If the line width is more than about 10 mu m, the electrode pattern may be visually recognized from outside. Preferably, the linewidth of the mesh wire may be between about 0.5 microns and about 7 microns. More preferably, the linewidth of the mesh wire may be between about 1 [mu] m and about 3.5 [mu] m.

Further, the thickness of the mesh line may be about 100 nm to about 500 nm. If the thickness of the mesh wire is less than about 100 nm, the electrode resistance may increase and the electrical characteristics may deteriorate. If the mesh wire thickness exceeds about 500 nm, the overall thickness of the touch window may become thick and the process efficiency may be deteriorated. Preferably, the thickness of the mesh line may be from about 150 nm to about 200 nm. More preferably, the thickness of the mesh line may be from about 180 nm to about 200 nm.

Since the sensing electrode 200 has a mesh shape, for example, the pattern of the sensing electrode 200 on the display area can be made invisible in the effective area AA. That is, even if the sensing electrode 200 is formed of metal, the pattern can be made invisible. Also, even if the sensing electrode 200 is applied to a touch window of a large size, the resistance of the touch window can be lowered.

When the size of the alignment portion is more than 1 mm, the width of the bezel region may increase.

The alignment portion may be spaced apart from the effective area AA by a distance of about 1 mm to about 10 mm. For example, the alignment portion may be spaced from the effective area AA by a distance of about 1 mm to about 5 mm.

If the spacing distance is less than about 1 mm, the alignment portions may move into the effective region due to the tolerance during lamination, thereby reducing the visibility.

For example, the unit interval of the scale area, which is the second area 420b of the second alignment part 420, may be 0.01 mm to 0.05 mm.

Since the position of the first alignment portion 410 can be grasped during the process based on the second region 420b, that is, the scale region, the alignment error can be determined.

For example, referring to FIG. 5, when four overlapping regions are formed at the ends of the first and second alignment portions 410 and 420, the alignment portions are accurately positioned without misalignment .

That is, one end of the first aligning portion 410 and one end of the second aligning portion 420 are not overlapped with each other, and the other end of the first aligning portion 410 and the end of the second aligning portion 420 When the other ends do not overlap, it is possible to easily determine that an alignment error has occurred.

Therefore, the touch window according to the embodiment can prevent the alignment errors of the first and second alignment portions, thereby improving the reliability.

In addition, since the unit area of the second area 420b, that is, the scale area can be read out, the first area 420b can be read based on the x- and y- By checking the degree of misalignment of process 410 during the process, it is possible to improve the process efficiency by modifying the quantitative value of the alignment that may occur during the process. Also, the process cost can be reduced.
