Before describing embodiments of the present invention, some terms used herein will be described. First, it should be noted that the term "substrate" is used for manufacturing a touch screen sensor and may also be referred to as "film" in the present specification. In addition, the touch screen sensor may be manufactured by forming the two substrates by using the substrate alone or the substrate as the upper substrate and the lower substrate, and bonding them. The first sensor unit is referred to herein as the upper substrate or the lower substrate. Note that the substrate may be any one of the substrates, and the second sensor unit may be any one of the lower substrate and the upper substrate, and the first and second sensor units may be named for use without distinguishing between upper and lower substrates. Should be.

Hereinafter, the touch screen sensor substrate constituting the touch screen sensor and the touch screen panel will be described, and the touch screen sensor and the touch screen panel including the same according to the present invention will be described in detail.

2 is an exemplary view illustrating a sensing unit and a sensing connection unit of a touch screen sensor substrate. Referring to FIG. 2A, the touch screen sensor substrate includes a plurality of sensing units 110 formed of electrodes connected to one surface of a substrate in a predetermined direction, and electrodes connected in a pattern of the same or similar direction as that of the pattern. It is formed as, and includes a sensing connection unit 120 for connecting the sensing unit 110.

Also, referring to FIG. 2 (b), the touch screen sensor substrate is adjacent to the sensing unit 110 and is the same as or similar to the direction of the pattern (although there is an error that is not the same, but the pattern is not recognized). And a plurality of dummy parts 130 formed of electrodes connected in a pattern in one direction to reduce visibility of the sensing part 110 and connecting the dummy parts 130. Not shown) may be further included.

Here, the sensing unit 110 is an electrode provided to detect a user's touch signal and is formed of a conductive material in the present invention, and the conductive material may be opaque.

The dummy unit 130 is an electrode formed adjacent to or adjacent to the sensing unit 110, and as the name implies, a dummy is formed in a pattern having the same or similar shape as that of the sensing unit 110, but the user It means an electrode or a combination thereof formed in an inactive state so as not to detect a touch signal. Therefore, the sensing unit 110 and the dummy unit 130 are formed to be electrically insulated. The reason for forming the dummy part 130 on the substrate is that the sensing unit 110, which is not formed of a transparent electrode material, is formed on the front surface of the touch screen sensor, and the sensing unit 110 is formed by external light irradiated to the touch screen sensor. This is to prevent the phenomenon which is recognized.

In addition, in FIG. 2, although the sensing unit 110 and the dummy unit 130 are illustrated as being straight, the present invention is not limited thereto. For example, the sensing unit 110 and the dummy unit 130 may be formed in various shapes. For example, the entire sensing unit 110 may be formed. The shape can be formed into a diamond, trapezoid, rhombus, or the like.

Meanwhile, the electrode is an electrode provided to transmit a touch signal sensed by the sensing unit 110 to an external driving circuit (not shown), and forms the sensing unit 110 and the dummy unit 130 on the substrate 100. It is preferable to be formed at the same time. In the present invention, the matters related to the electrodes are beyond the scope of the present invention, and thus a detailed description thereof will be omitted.

The dummy unit 130 and the dummy when the sensing unit 110, the dummy unit 130, and the sensing connection unit 120 or the dummy connection unit connecting the sensing unit 110 and the sensing unit 110 of the touch screen sensor substrate are included. The dummy connection part (not shown) connecting the parts 130 is preferably formed of electrodes connected in a same or similar pattern in a predetermined direction. In the present embodiment, the pattern in a constant direction is a continuous pattern. In this embodiment, as shown in FIG. 2, it is preferable that the lines formed in the predetermined direction intersect with each other.

The same or similar pattern in this embodiment is not only that the repetition period and the repeating shape are geometrically identical in the repetition of the pattern, but also that the repetition period and the repetition shape are formed within an acceptable error range predetermined by software. It is preferable to include the case where it becomes. Therefore, in the present exemplary embodiment, the electrode patterns of the sensing unit 110 and the dummy unit 130 as well as the sensing connection unit 120 and the dummy connection unit that connect them are the same so that the electrode patterns of the dummy connection unit (not shown) are the same. The visibility of the detection unit 110 may be reduced.

In addition, the pattern of the predetermined direction is formed in a continuous pattern, it is preferable that a portion of the pattern is cut off at the boundary between the sensing unit 110 and the dummy portion 130. In addition, a portion of the pattern is broken when the sensing unit 110, the dummy unit 130, the sensing connection unit 120, and the dummy connection unit exist, and the edge of the pattern of the dummy connection unit (not shown) is opened. It is preferable.

As described above, a part of the pattern cut off at the boundary between the detector 110 and the dummy part 130 is for the detector 110 and the dummy part 130 to be electrically insulated from each other, and is also broken. The edges of the pattern of the sensing unit 110 and the dummy unit 130 are opened, which means that the edges are not connected to the edge electrodes as shown in FIG. 3. 3 is an enlarged view of a part of FIG. 2 (b). Referring to FIG. 3, the edge is opened and connected to the edge electrode to solve the problem of continuity disappearing and disconnection. The visibility of the detector 110 may be reduced by allowing the user to recognize that the user is continuous.

In addition, in the present embodiment, the edge is formed to be open means that the pattern is formed alternately long and short at the edge. Referring to FIG. 4, the sensing unit 110 or the dummy unit 130 may be formed of a plurality of electrodes arranged to alternately shorten and lengthen electrodes at edges. Alternate in this embodiment is that the short and long are repeated in order, as shown in Figure 4, the long and short electrodes (e) are alternately repeated at the edge of the pattern or regular or irregular according to a predetermined pattern This includes repeated cases.

In the present embodiment, the pattern is preferably a grid-shaped pattern in which lines formed in a predetermined direction cross each other as shown in FIG. 2. The lattice shape in which lines formed in a predetermined direction cross each other means a mesh-like or mesh-shaped lattice pattern as a whole.

It is also desirable that the lattice-shaped lines that cross each other of the pattern have the same line width and pitch that define the spacing between the lines, or have a line width or pitch of preset similarity. In the present embodiment, the line width or pitch is the same or has a line width or pitch of a preset similarity means that the line width or pitch has a predetermined range of values shown in Table 1 to obtain a predetermined fill factor.

Line width (탆) Pitch (μm) Fill Factor (%)

1 to 5

100 1.9 to 10.0 200 2.5 to 5.0 300 1.9 to 3.5 400 1.4 to 2.5 500 0.4 to 1.9 600 0.3 to 1.7

6 to 10

100 11.0-19.0 200 5.9 to 10.0 300 3.9 to 7.0 400 2.9 to 5.0 500 2.3 to 3.9 600 1.9 to 3.3

Referring to FIG. 5 and Equation 1 below, the fill factor is a lattice pattern (shape of the sensing unit 110 or the dummy unit 130) formed on one substrate or a lattice formed by stacking multiple substrates. It is defined as follows as the ratio which divided the area occupied by the electrode layer (meaning the electrode layer formed by the sensing part 110 and the dummy part 130) from the area of the arbitrary board | substrate of shape.

When the fill factor defined as described above is less than 1.4, the transmittance is increased, but there is a possibility that the touch operation is not performed smoothly due to the increase in the resistance of the electrode layer and the decrease in the contact area of the capacitance. When the fill factor is greater than 10, the electrode layer is the substrate. Because of the large area occupied in, the transmittance is lowered and the pattern is recognized.

Accordingly, the Fill Factor preferably has a value between 1.4 and 10.0%, more preferably between 1.4 and 7.0%. It is preferable to adjust the line width and pitch as appropriate according to the value of the Fill Factor.

Also, in this embodiment, the mutually intersecting grid lines are preferably tilted according to a predetermined angle. Referring to FIG. 4, the lines formed in this embodiment have a pattern inclined at 45 ° with respect to the horizontal axis, and the inclined form increases the ratio of electrodes for detecting a touch input per unit area to increase the accuracy of detection. Further, the predetermined angle to be tilted is preferably an angle determined to prevent occurrence of moiré phenomena due to a pattern in a predetermined direction and mutual interference between the pattern and another pattern. In the present embodiment, the interference between the pattern and the other pattern may be that the patterns of the electrodes formed on the substrates cause interference when a plurality of substrates sensing touch positions in different directions are stacked, or the image information display unit displaying image information. It may be generated between the patterns formed by the plurality of pixels included in the.

The moire phenomenon is generally a natural interference phenomenon formed when two independent periodic patterns are stacked at an angle. The moiré pattern is represented by wavy waves, ripples, and fluctuations in intensity in the form of small bundles that are stacked with the display image on the screen.

In this embodiment, the prevention of moiré phenomenon is to prevent the mutual interference of the patterns, so that the wave forms, the ripples, and the small bundles that are stacked with the display image of the screen due to the pattern stacking. It may be to give a twist according to a predetermined first angle between the directions of the patterns so that the intensity fluctuations of the form does not occur, or to prevent the user from recognizing the intensity fluctuations formed according to the lamination. At this time, not recognizing by the user means that the interval where the formed pattern is repeated is an interval equal to or smaller than the resolution (a degree of the interval which can be discerned by the human eye).

In addition, the tilting angle in the present embodiment includes an angle that may be determined differently according to the line width and the pitch in addition to the angle shown in FIG. 4. In addition, since the pattern of a certain direction in the present embodiment has a certain direction based on the tilted pattern, the dummy connector (not shown) when the sensing unit 110, the dummy unit 130, the sensing connector 120, and the dummy connector are present. C) is preferably formed of electrodes connected in a pattern of the same or similar direction with respect to the tilted pattern.

The resin layer 102 is laminated on the substrate 100 and has a patterned intaglio on one surface thereof. Specifically, the resin layer 102 is laminated on the transparent substrate, and the intaglio shape is formed by imprinting on the resin layer 102 using an embossed mold corresponding to the desired intaglio shape. That is, the intaglio is formed in the resin layer 102 using the embossed mold. Whereby one or more engraved patterns are formed in a pattern. A cross section of the resin layer 102 in which the intaglio is formed may have an intaglio shape of any one of a rectangle, a triangle, and a trapezoid. If the embossed shape of the mold is a square, the intaglio shape formed on the resin layer 102 is also a rectangle. If the embossed shape of the mold is a triangle, the intaglio shape formed on the resin layer 102 is also a triangle. The engraved shape formed at 102 is also trapezoidal. In the resin layer 102, the "width" of the intaglio may be 1 μm to 10 μm, the “depth” of 1 μm to 10 μm, and the “pitch” between the intaglio and the intaglio may be 200 μm to 600 μm. Of course, this is merely an embodiment, and it is a matter of course that the width, depth and pitch of the engraving can be variously modified. In addition, the resin layer 102 is preferably implemented by UV (UltraViolet) resin or thermosetting resin.

The electrode layer 112 is formed by filling a conductive material in the intaglio. When the sensing unit 110, the dummy unit 130, the sensing connection unit 120, and the dummy connection unit exist, a dummy connection unit (not shown) is present. It is formed by the electrode layer 112. Examples of the conductive material include copper, silver, aluminum, nickel, chromium, nickel-phosphorus, and the like.

The sensing unit 110 and the dummy unit 130 may be formed at the same time, and may be formed of the same conductive material. However, as described above, the sensing unit 110 is an electrically active electrode that senses and transmits a touch signal. The unit 130 is an electrically inert electrode.

In addition, the touch screen sensor substrate may further include a black layer 114 which reduces the visibility of the dummy connector (not shown) when the detector 110, the dummy unit 130, the sensing connector 120, and the dummy connector are present. Can be. The black layer 114 is preferably stacked above the negative electrode layer 112 or between the resin layer 102 and the electrode layer 112. Referring to FIG. 6A, the black layer 114 is stacked between the resin layer 102 and the electrode layer 112 to surround the electrode layer 112 at an intaglio formed in the resin layer 102. It is possible to further reduce the visibility of the electrode layer 112 by including a black layer 114, referring to Figure 6 (b) according to another embodiment, the black layer 114 wraps around the electrode layer 112 The electrode layer 112 is covered in a form not covering the inside of the intaglio. Accordingly, the sensing substrate according to the present embodiment uses the black layer to prevent the electrode layer from being visually recognized from the outside.

Hereinafter, a process of forming an electrode by forming and filling an intaglio in a resin layer according to at least one embodiment of the present invention will be described. 8 is a flowchart illustrating a manufacturing method of a touch screen sensor substrate according to an embodiment of the present invention. Referring to FIG. 8, the manufacturing method of the touch screen sensor substrate includes a resin layer applying step S100, an intaglio forming step S200, an electrode layer forming step S300, and a black layer forming step S400.

In the resin layer coating step (S100), a resin layer is laminated on a substrate, and a resin film or glass may be used as the substrate. The substrate is preferably formed of a transparent substrate. That is, the substrate having a certain transparency, it may be formed in the form of a transparent thin film using at least one of the above-described materials. The thickness of the substrate is suitably in the range of 25 to 250 μm, and the light transmittance of 80% or more, more preferably 90% or more, to improve luminance.

The intaglio forming step (S200) imprints the resin layer into a mold to form a patterned intaglio. In the case of using the UV curable resin or the thermosetting resin as the resin layer 102, the mold is pressed onto the material before curing and the UV or heat is applied while curing the resin layer 102 by pressing or pressing the mold. Can be formed. At this time, the embossed mold for forming the intaglio in the resin layer 102 is preferably made to have a haze of 4% or less after the intaglio patterning using a material having a sufficiently low surface roughness, which is 4% of Haze. If it exceeds, the brightness is lowered, which adversely affects product performance. In the present embodiment, since the sensing unit 110, the sensing connection unit 120, and the dummy unit 130 are formed through an electrode layer forming step in which a conductive material is filled in the intaglio formed in the intaglio forming step, the intaglio forming step is the touch screen described above. It is a step of engraving the structure of the electrode of the sensor substrate.

Therefore, the intaglio forming step (S200) is a sensing unit 110 formed in a pattern of a predetermined direction on one surface of the substrate and a sensing connection unit 120 that is formed in the same direction as the direction of the pattern and connects the sensing unit 110. The intaglio is formed to form). In addition, forming the intaglio may include a dummy part 130 and a dummy connection part adjacent to the sensing part 110 and formed in a pattern in the same direction as the direction of the pattern and reducing visibility of the sensing part 110. If it further comprises the step of forming an intaglio to form a dummy connection (not shown).

As described above, the pattern in a predetermined direction is formed in a continuous pattern, but it is preferable that a part of the pattern is cut off at the boundary between the sensing unit 110 and the dummy part 130, and a part of the pattern The broken part is preferably formed by opening the edge of the pattern of the dummy connection part (not shown) when the sensing part 110, the sensing connection part 120, the dummy part 130, and the dummy connection part exist. A part of the pattern broken at the boundary between the 110 and the dummy part 130 is for the electrical insulation part and the dummy part 130 to be electrically insulated from each other. That is, the edge of the pattern of the unit 130 is not connected to the edge electrode.

As described above, the edge is opened and connected to the edge electrode, so that the continuity disappears and the disconnection is solved. In fact, the user may recognize that the electrode is continuous when viewed at a fine interval. Can be reduced. In addition, in the present embodiment, the edge may be formed to be open so that the pattern may be formed of a plurality of electrodes arranged such that the electrodes are alternately short and long at the edge of the sensing unit 110 or the dummy unit 130. .

The pattern formed in the intaglio forming step (S200) according to the present embodiment is preferably a lattice-shaped pattern in which lines formed in a predetermined direction cross each other. It is preferred that the pitches that define the spacing be the same or have a linewidth or pitch of preset similarity. It is also preferable that the mutually intersecting grid lines are tilted according to a predetermined angle.

Electrode layer forming step (S300) is to fill the conductive material in the intaglio formed in the intaglio forming step (S200), the sensing unit 110, the sensing connection portion 120 and the dummy portion 130 is an electrode layer forming step (S300) ) Is formed in the electrode layer 112 filled with a conductive material. Examples of the conductive material include copper, silver, aluminum, nickel, chromium, nickel-phosphorus, and the like.

Therefore, in the present embodiment, the sensing unit 110 and the dummy unit 130 may be formed at the same time, and may be formed of the same conductive material, but as described above, the sensing unit 110 may detect and transmit a touch signal. The dummy electrode 130 is an electrically inert electrode.

The electrode layer forming step S300 may be formed through the formation of the seed layer, and more specifically, the 'seed layer' and the 'resin layer 102' to be formed later on the inner surface of the intaglio and the surface of the resin layer 102. It is preferable to form a surface treatment layer by surface treatment for improving the adhesion of the liver.

As the surface treatment, chemical etching or catalytic treatment using an alkaline aqueous solution, plasma or ion beam treatment and the like can be applied.

Then, a metallic seed layer is formed on the surface treatment layer. The seed layer may be formed using a metal material by electroless plating, CVD deposition, sputtering, or printing. In the present specification, the metallic material means the electrode material mentioned above. The electrode layer may then be formed by performing electroless plating, electroplating, CVD deposition, sputtering, coating or printing on the seed layer.

In the method of removing the seed layer from the surface of the resin layer other than the intaglio pattern region, a resin having a resistance to etching is filled in the inside of the intaglio, which is the pattern region, and then precipitated in an etching solution to selectively remove the seed layer formed on the surface of the resin layer. Remove In this case, the chemical used for etching includes any one of nitric acid series, sulfuric acid series, hydrochloric acid series, copper sulfate series, ferric chloride, and cupric chloride.

In addition, the electrode layer forming step (S300) may form an electrode without a seed layer in the intaglio of the resin layer, and more specifically, by forming an electrode layer without the seed layer in the intaglio, the conductive material is engraved with the surface of the resin layer 102. After the coating, the remaining material on the surface of the resin layer 102 is removed by a blade. In more detail, a substrate for a touch screen panel may be manufactured by coating a conductive material without a metal seed layer on the resin layer 102 and wiping or scraping off the remaining surfaces on the other surface using a blade. Can be.

The black layer forming step S400 is conductive and is stacked on top of the intaglio electrode layer 112 formed in the electrode layer forming step S300. In the present embodiment, the black layer forming step (S400) reduces the visibility of the electrode layer 112 by stacking the black layer 114 as described above with reference to FIG. 6B.

Hereinafter, the cross-sectional structure of the touch screen panel in the present embodiment will be described.

In the touch screen panel according to the present invention, two substrates are stacked on a liquid crystal panel (LCD panel), and each substrate is composed of UV resin, PET, and hard coating. That is, each substrate may be composed of a resin layer including an electrode layer, PET laminated on the resin layer, a hard coating of a predetermined hardness or more laminated on the PET, and these substrates are formed by an adhesive layer (OCA). Although it can be bonded, it is also possible to bond each substrate through the adhesive layer (OCA) between the coating and the resin layer.

The touch screen panel according to the present invention can also be configured by stacking an AR / LR / AG layer on the top of the touch screen panel.

The touch screen panel according to the present invention may be configured by forming an adhesive layer (OCA) on the top of the touch screen panel, and laminating at least one of glass, acrylic, or a transparent substrate having a predetermined hardness or more on the adhesive layer.

The upper substrate is formed by laminating one of glass, acrylic or a transparent substrate having a predetermined hardness or more on top of the UV resin. That is, the upper substrate may be made of one of a resin layer including an electrode layer, glass laminated on the resin layer, acrylic, or a transparent substrate having a predetermined hardness or more, and the upper substrate and the lower substrate may be bonded by an adhesive layer (OCA). Moreover, it is also possible to bond these board | substrates through the adhesive layer on the coating of a lower board | substrate, and the resin layer of an upper board | substrate.

According to the present invention, a touch screen panel includes a glass, acrylic, or a transparent substrate having a predetermined hardness or more laminated on a liquid crystal panel, and a lower substrate on which a resin layer including an electrode layer is stacked, and a glass on a resin layer including an electrode layer. An upper substrate on which one of acrylic or a transparent substrate having a predetermined hardness or more is laminated is bonded by an adhesive layer.

The touch screen panel is laminated with a layer selected from any one of glass, acrylic, or a transparent substrate having a predetermined hardness or more, and the resin layer stacked on the upper and lower portions of the selected layer has an electrode layer included in the resin layer directly on the selected layer. It is preferable to laminate | stack so that it may not contact. Because the resin layer including the electrode layer formed on the intaglio can be directly bonded to the layer selected from any one of the glass, acrylic or a transparent substrate having a predetermined hardness or more, thereby reducing the use of the pressure-sensitive adhesive, thereby reducing the manufacturing cost. Because there is.

On the other hand, in the case of a touch screen panel having a structure in which the intaglio of the resin layer is in contact with the LCD panel, when the LCD panel and the resin layer are in contact, the intaglio formed in the resin layer serves as illuminance to degrade image quality on the display. Therefore, in order to improve such a problem, the intaglio of the resin layer including the electrode layer must be filled with OCA or pressure-sensitive adhesive.
