The second connection electrodes 60 and the shield layer 70 may be formed of the same material.

The substrate 10 is a substrate 10 that can function as a support for supporting various elements of the touch screen panel 100 and is made of a transparent insulating material. The substrate 10 may be made of a rigid material such as reinforced glass or acrylic resin or a rigid PET (Polyethylene Terephthalate), PC (Polycarbonate), PES (Polyether sulfone), PI (Polyimide), PMMA (PolyMethly MethaAcrylate) Lt; / RTI >

The substrate 10 may be a cover glass applied to the touch screen panel 100. In this case, the substrate 10 may be made of reinforced glass or a high hardness plastic material.

The first region 10A may be located at the center of the substrate 10 and the second region 10B may be a region surrounding the first region 10A located at the outer periphery of the first region 10A . Although the second region 10B is shown as an outer region surrounding the first region 10A for the sake of convenience of explanation in FIG. 1, the second region 10B can be located on both sides of the first region 10A , The first region 10A and the second region 10B may be arranged alternately with each other.

The first area 10A of the substrate 10 may be an area for sensing input information generated by a touch or a gesture of the user and a first area 10A of the substrate 10, The sensing electrodes 20, the first connecting electrodes 30, the second sensing electrodes 40, the insulating layer 50, the second connecting electrodes 60, and the shield layer 70 may be formed . The first sensing electrodes 20, the first connecting electrodes 30, the second sensing electrodes 40, the insulating layer 50, and the second connection electrodes 40 formed in the first region 10A of the substrate 10, A more detailed description of the electrodes 60 and the shield layer 70 will be described later. In some embodiments, the first area 10A may be a display area in which an image or an image is displayed.

The second area 10B of the substrate 10 may be an area in which various wiring patterns or the like for transmitting sensing signals generated in the touch sensing area exist. Although a wiring pattern or the like that may be formed in the second region 10B is omitted for the sake of convenience of description, it is to be understood that the wiring patterns may be formed in the second region 10B, Do. In some embodiments, the second area 10B may be a non-display area where no image or image is displayed.

Although the first region 10A and the second region 10B are distinguished from each other in FIG. 2 for convenience of explanation, the first region 10A and the second region 10B may be integrated, The first sensing electrodes 20 and / or the second sensing electrodes 40 may be formed to sense touch input information of a user.

The first sensing electrodes 20 and the second sensing electrodes 40 arranged alternately and the first connecting electrodes 30 electrically connecting the first sensing electrodes 20 are formed on the substrate 10 do. Reference is also made to FIG. 3 for a more detailed description of the first sensing electrodes 20, the first connecting electrodes 30, and the second sensing electrodes 40.

3 is an enlarged view of the area A in Fig. 3, only the substrate 10, the first sensing electrodes 20, the first connecting electrodes 30, and the second sensing electrodes 40 among the elements of the touch screen panel 100 Respectively.

Referring to FIGS. 2 and 3, the first sensing electrodes 20 and the second sensing electrodes 40 are formed alternately in the substrate 10.

First, the first sensing electrodes 20 are separated from each other in the substrate 10 and arranged in a first direction. For example, the first sensing electrodes 20 may be arranged in the first direction separated from each other in the first region 10A of the substrate 10. [ The first sensing electrodes 20 may be arranged in the column direction as X-axis sensing electrodes separated from each other in the first region 10A of the substrate 10. [ The first sensing electrodes 20 may be formed in various shapes. 2 and 3, the first sensing electrodes 20 are rhombic for convenience of explanation. However, the first sensing electrodes 20 may have various shapes such as a column shape, a patch shape, a circular shape, and a polygonal shape .

The second sensing electrodes 40 are arranged in the second direction separated from each other in the substrate 10. For example, the second sensing electrodes 40 may be arranged in the second direction separated from each other in the first region 10A of the substrate 10. [ The second direction means a direction different from the first direction, and means a direction perpendicular to the first direction. The second sensing electrodes 40 may be formed on the same plane as the first sensing electrodes 20 in the first region 10A of the substrate 10. [ The second sensing electrodes 40 may be arranged in the row direction, separated from each other in the first region 10A of the substrate 10 as Y-axis sensing electrodes. The second sensing electrodes 40 may be formed in various shapes and may have the same shape as the first sensing electrodes 20. 2 and 3, the second sensing electrodes 40 are rhombic for convenience of explanation. However, the second sensing electrodes 40 may have various shapes such as a column shape, a patch shape, a circular shape, and a polygonal shape .

The first connection electrodes 30 are formed on the substrate 10 to electrically connect the first sensing electrodes 20. For example, the first connection electrodes 30 may electrically connect the first sensing electrodes 20 in the first region 10A of the substrate 10. [ The first connection electrodes 30 may be formed on the same plane as the first sensing electrodes 20 and the first connection electrodes 30 in the first region 10A of the substrate 10. [ The first connection electrodes 30 may be formed between neighboring first sensing electrodes 20 among the first sensing electrodes 20 to electrically connect neighboring first sensing electrodes 20. Therefore, the first connection electrodes 30 electrically connect the neighboring first sensing electrodes 20 and the second sensing electrodes 40, which are adjacent to the neighboring neighboring first sensing electrodes 20, As shown in FIG.

The first sensing electrodes 20, the first connecting electrodes 30, and the second sensing electrodes 40 may be formed of substantially the same material, and may be formed substantially simultaneously. The first sensing electrodes 20, the first connecting electrodes 30 and the second sensing electrodes 40 may be formed of a transparent conductive material such as ITO (Indium Tin Oxide), IZO Oxide, and ZO (zinc oxide), carbon nanotubes, metal nanowires, conductive polymers, and the like.

The first sensing electrodes 20, the first connecting electrodes 30 and the second sensing electrodes 40 are formed by collectively sputtering a transparent conductive material to the first region 10A of the substrate 10 The first sensing electrodes 20, the first connecting electrodes 30 and the second sensing electrodes 40 by etching the first sensing electrodes 20, the second sensing electrodes 30, and the second sensing electrodes 40. For example, when ITO is used as a transparent conductive material, it is collectively sputtered to the first region 10A of the substrate 10 at about 130 to 350 DEG C, and then the first sensing electrodes 20, The first sensing electrodes 20, the first connecting electrodes 30 and the second sensing electrodes 40 can be formed by etching in accordance with shapes of the electrodes 30 and the second sensing electrodes 40 have.

2 and 3, the first sensing electrodes 20, the first connecting electrodes 30 and the second sensing electrodes 40 are formed only in the first region 10A of the substrate 10, The first sensing electrodes 20, the first connecting electrodes 30 and the second sensing electrodes 40 are formed in the second region 10B of the substrate 10 as well And the input information generated by the touch of the user or the gesture can be detected in the second area 10B of the substrate 10 as well.

Referring again to FIG. 2, on the first sensing electrodes 20, the first connecting electrodes 30, and the second sensing electrodes 40 to cover the entire first region 10A of the substrate 10, An insulating layer 50 is formed. The insulating layer 50 may be formed of a transparent insulating material. See also FIGS. 4 and 5 for a more detailed description of the insulating layer 50. FIG.

Figs. 4 and 5 are enlarged views of the area A in Fig. In FIG. 4, only the insulating layer 50 among the elements of the touch screen panel 100 is shown for convenience of explanation. 5 shows an insulating layer 50 (see FIG. 4) on the substrate 10, the first sensing electrodes 20, the first connecting electrodes 30 and the second sensing electrodes 40 shown in FIG. The first sensing electrodes 20, the first sensing electrodes 20, the second sensing electrodes 30, and the second sensing electrodes 30 of the elements of the touch screen panel 100 for convenience of explanation. Only the electrodes 40 and the insulating layer 50 are shown. In addition, since the insulating layer 50 is formed on the first sensing electrodes 20, the first connecting electrodes 30, and the second sensing electrodes 40, the first sensing electrodes 20 The first connection electrodes 30 and the second sensing electrodes 40 are shown by dotted lines.

Referring to FIGS. 2, 4 and 5, the first sensing electrodes 20, the first connecting electrodes 30, and the second sensing electrodes 20 are formed so as to cover the first region 10A of the substrate 10, An insulating layer 50 is formed on the first sensing electrodes 40 and the insulating layer 50 includes openings 51 for opening a part of each of the second sensing electrodes 40.

Each of the openings 51 can open a part of each of the second sensing electrodes 40. [ Each of the openings 51 may correspond to each of the second sensing electrodes 40, and each of the openings 51 may be formed so as to be adjacent to the neighboring openings 51.

Since the openings 51 are formed to electrically connect neighboring second sensing electrodes 40, the positions, shapes, and sizes of the openings 51 may be variously set. However, if the distance between the openings 51 is long, the length of the second connection electrodes 60 electrically connecting the neighboring second sensing electrodes 40 through the openings 51 becomes long, The resistance of the connecting electrodes 60 is increased. Accordingly, in the touch screen panel 100 according to an embodiment of the present invention, the openings 51 may be formed to correspond to the boundary regions of the corresponding second sensing electrodes 40.

The opening 51 of the insulating layer 50 may be formed to have an area of about 100 탆 X 100 탆 to about 500 탆 X 500 탆, for example, a screen printing method using a screen mask, a spin coating method, . ≪ / RTI >

2, the second connection electrodes 60 connecting the second sensing electrodes 40 through the openings 51 of the insulation layer 50 and the shield layer 70 are formed on the insulation layer 50 As shown in FIG. See also FIGS. 6 and 7 for a more detailed description of the second connecting electrodes 60 and the shield layer 70.

Figs. 6 and 7 are enlarged views of the area A in Fig. 6, only the second connecting electrode 60 and the shield layer 70 among the elements of the touch screen panel 100 are shown for convenience of explanation. Fig. 7 is a cross-sectional view of the substrate 10, the first sensing electrodes 20, the first connecting electrodes 30, the second sensing electrodes 40, and the insulating layer 50 shown in Fig. The second connecting electrode 60 and the shield layer 70 are formed as shown in FIG. 7. In FIG. 7, the first sensing electrodes 20, the first connecting electrodes 30, and the second sensing electrodes 40 are shown by dotted lines Respectively.

Referring to FIGS. 2, 6 and 7, the second connection electrodes 60 electrically connect the second sensing electrodes 40 through the opening 51 of the insulating layer 50 on the insulating layer 50 . The second connection electrodes 60 may electrically connect neighboring second sensing electrodes 40 among the second sensing electrodes 40.

In the touch screen panel 100 according to an embodiment of the present invention, the insulating layer 50 is formed to cover the first sensing electrodes 20, the first connecting electrodes 30, and the second sensing electrodes 40 And the second connection electrodes 60 electrically connect the neighboring second sensing electrodes 40 through the openings 51 that open partial areas of the second sensing electrodes 40. [ Therefore, problems such as a short circuit due to defective alignment between the sensing electrode, the insulating layer, and the connection electrode can be solved.

Referring again to FIGS. 2, 6 and 7, a shield layer 70 is formed on the insulating layer 50. The shield layer 70 does not overlap with the second connection electrode 60 formed on the insulating layer 50 and may be formed over the whole surface of the insulating layer 50. [ That is, the shield layer 70 includes an area for opening the space in which the second connection electrode 60 is formed, and the second connection electrode 60 and the shield layer 70 are formed of the same layer, Lt; / RTI >

1, elements of the touch screen panel 100 opposed to the display panel 900 are second connection electrodes 60 and a shield layer 70, and the substrate 10 of the touch screen panel 100 Is located on the opposite side of the display panel 900. [

The second connection electrodes 60 and the shield layer 70 may be formed of substantially the same material, and may be formed substantially simultaneously. The second connection electrodes 60 and the shield layer 70 may be formed of a transparent conductive material and may be formed of an oxide such as ITO (Indium Tin Oxide), IZO (Indium Zinc Oxide), ZO (Zinc Oxide) , Carbon nanotubes, metal nanowires, conductive polymers, and the like.

The second connection electrodes 60 and the shield layer 70 are formed by collectively sputtering a transparent conductive material on the insulating layer 50 and then etching the second connection electrodes 60 and the shield layer 70 according to the shape thereof , And may be formed of the same material at the same time. For example, when ITO is used as the transparent conductive material, the ITO is collectively sputtered in the insulating layer 50 at a temperature of about 130 ° C. to 350 ° C., and then is sputtered according to the shape of the second connection electrodes 60 and the shield layer 70 The second connection electrodes 60 and the shield layer 70 may be formed by etching.

The gap between the touch screen panel 100 and the display panel 900 may be widened in order to solve the other malfunctions and stability degradation due to the noise generated by being disposed adjacent to the touch screen panel 100 and the display panel 900, A passivation process is performed, or a separate transparent electrode film is used. However, there is an additional problem that the use of the above measures increases the overall thickness and increases the process and material costs.

In the touch screen panel 100 according to an embodiment of the present invention, only the second connection electrodes 60 for connecting the sensing electrodes under the insulation layer 50 are formed on the insulation layer 50, A shield layer (70) is formed over the entire surface of the layer (50). In addition, the shield layer 70 is formed not in a separate process from the second connection electrodes 60 but in the same process as the second connection electrodes 60 at the same time. Therefore, in the touch screen panel 100 according to the embodiment of the present invention, it is possible to minimize other malfunctions and stability degradation due to noise generated when the touch screen panel 100 is disposed adjacent to the touch screen panel 100 and the display panel 900, The increase in the total thickness of the display apparatus 1000 and the increase in the process and material costs can be minimized.

8 is an enlarged view of region A of FIG. 2 according to another embodiment of the present invention. 8 shows a second connection (not shown) on the substrate 10, the first sensing electrodes 20, the first connecting electrodes 30, the second sensing electrodes 40 and the insulating layer 50 shown in Fig. The first sensing electrodes 20, the first connecting electrodes 30, and the second sensing electrodes 40 are shown by dotted lines in FIG. 8, in which an electrode 60 and a shield layer 170 are formed. For convenience of explanation, elements substantially the same as the elements shown in the drawing of FIG. 7 are denoted by the same reference numerals, and redundant description thereof will be omitted.

2 and 8, a shield layer 170 is formed on the insulating layer 50 and a shield layer 170 is formed on at least one of the dummy patterns 171 and the dummy patterns 171, And may include a connection pattern 172. As described above, since the second connection electrodes 60 and the shield layer 170 can be formed of substantially the same material and can be formed substantially simultaneously, the second connection electrodes 60 and the dummy patterns 171 and the connection pattern 172 may also be formed of substantially the same material and may be formed substantially simultaneously. In addition, the dummy patterns 171 are electrically connected by the connection pattern 172 to form one shield layer 70. In some embodiments, the minimum size of the dummy patterns 171 is 1 mm 2, and the minimum thickness of the insulating layer 50 may be 1 탆.

In the touch screen panel 100 according to another embodiment of the present invention, not only the second connecting electrodes 60 for connecting the sensing electrodes under the insulating layer 50 are formed on the insulating layer 50, Dummy patterns 171 are formed together over the entire surface of the layer 50. Accordingly, it is possible to minimize other malfunctions and stability deterioration due to noise generated when the display panel 900 is disposed adjacent to the touch panel 100 and the display panel 900, and to increase the overall thickness of the display device 1000, And the visibility can be improved according to the formation pattern of the second connecting electrodes 60 and the dummy patterns 171 formed on the insulating layer 50. [

Figures 9 and 10 are enlarged views of region B of Figure 8 in accordance with various embodiments of the present invention. Figures 9 and 10 illustrate various shapes of dummy patterns 171, 271 and connection patterns 172, 272 in accordance with various embodiments of the present invention.

Referring to FIG. 9, the dummy patterns 171 are rectangular in shape, and the connecting patterns 172 may be disposed at the respective corners of the dummy patterns 171. Thus, the dummy patterns 171 may be in a cross shape. In some embodiments, the shapes of the dummy pattern 171 and the connecting pattern 172 may be variously defined. For example, although not shown in FIG. 9, the connection pattern 172 may have a rectangular shape, and the dummy patterns 171 may be disposed at the respective corners of the connection pattern 172. Thus, the dummy patterns 171 are basically rectangular in shape, but each of the corner portions may be formed conformally to the connection pattern 172.

10, the dummy patterns 271 may have a rectangular shape, and the connection patterns 272 may be disposed so as to connect the sides of the adjacent dummy patterns 271 with each other. For example, the connection pattern 272 may be arranged to connect opposite sides of neighboring dummy patterns 271, and the connection pattern 272 may be a rectangular shape.

Although the shapes of the dummy patterns 171 and 271 and the shapes of the connection patterns 172 and 272 have been described with reference to FIGS. 9 and 10 for convenience of description, the present invention is not limited thereto. .

11 is an enlarged view of region A of Fig. 2 according to another embodiment of the present invention. Referring to FIG. 11, the sizes of the second connection electrodes 360 and the dummy patterns 371 are larger than the sizes of the second connection electrodes 60 and the dummy patterns 171 shown in FIG. When the sizes of the second connection electrodes 360 and the dummy patterns 371 are increased, it is easier to solve problems such as a short circuit due to defective alignment between the sensing electrode, the insulating layer, and the connection electrode.

Referring to FIG. 11, the connection pattern 372 may electrically connect neighboring dummy patterns 371 in various directions. For example, the connection pattern 372 may electrically connect neighboring dummy patterns 371 in the first direction, and may electrically connect neighboring dummy patterns 371 in the second direction. That is, since the connection patterns 372 only need to connect the dummy patterns 371 to one another, the neighboring dummy patterns 171 can be electrically connected to each other in various directions.

Figure 12 is an enlarged view of region A of Figure 2 according to another embodiment of the present invention.

Referring to FIG. 12, the dummy patterns 471 may have a size smaller than a size corresponding to either one of the first sensing electrode 20 and the second sensing electrode 40. That is, each of the dummy patterns 471 overlaps with the first sensing electrode 20 of one of the first sensing electrodes 20 or overlaps with the second sensing electrode 40 of one of the second sensing electrodes 40 Can be overlapped. The shapes of the dummy patterns 471 may be substantially the same as the shapes of one first sensing electrode 20 or one second sensing electrode 40 in which each of the dummy patterns 471 overlap. 12, when the first sensing electrode 20 and the second sensing electrode 40 are formed in a rhombic shape, the dummy patterns 471 are formed in substantially the same shape as the rhombus . The dummy patterns 471 may be conformally formed along the outline of one of the first sensing electrodes 20 or one of the second sensing electrodes 40 in which the dummy patterns 471 are overlapped. Therefore, in addition to the effect of improving the visibility due to the formation of the dummy pattern 471, the occurrence of interference by the dummy pattern 471 can be prevented, and the accuracy of the touch position measurement can also be improved.

The connection pattern 472 can electrically connect neighboring dummy patterns 471. The connection pattern 472 can electrically connect neighboring dummy patterns 471 at respective corners. The connection pattern 472 is substantially the same as the connection pattern 172 of FIG. 8, except for the shape of the connection pattern 472, and redundant description will be omitted.

The touch screen panel 1100 is substantially the same as the touch screen panel 100 of FIG. 2, except that the touch screen panel 1100 further includes a flexible circuit board 80, and redundant description will be omitted.

The flexible circuit board (FPCB) 80 is a flexible circuit board 10, and is disposed at one end of the substrate 10. The flexible circuit board 80 may be attached to one end of the substrate 10 through various bonding processes. For example, anisotropic conductive film (ACF), anisotropic conductive paste (ACP), and anisotropic conductive adhesive (ACA) may be used as the bonding process, but various bonding processes may be used without limitation. In some embodiments, the flexible circuit board 80 may be attached to the second region 10B of the substrate 10. [

The first sensing electrode 20 and the second sensing electrode 40 formed on the substrate 10 are electrically connected to the flexible circuit board 80 through a wiring pattern (not shown) formed in the second region 10B of the substrate 10. [ To the touch sensor chip 83 of the flexible circuit board 80. The touch sensor chip 83 is electrically connected to the sensing electrode connection terminal 82 of the flexible circuit board 80 through a touch screen or gesture of the user, . The touch sensor chip 83 can receive a sensing signal from the first sensing electrode 20 and the second sensing electrode 40 to detect whether or not a contact has occurred or the number of contacts. 13, the touch sensor chip 83 is mounted on the flexible circuit board 80. However, the touch sensor chip 83 may be mounted on the main board of the display device 1000, It can be mounted in various positions depending on the design method.

In the touch screen panel 1100 according to another embodiment of the present invention, the shield layer 70 is electrically connected to the ground terminal 81 of the flexible circuit board 80 to maintain the ground state. Therefore, it is possible to minimize the noise that may occur between the driving of the touch screen panel 1100 and the driving of the display panel 900, and the problems such as malfunctions and stability that can be generated can be solved.

14 is a flowchart of a method of manufacturing a touch screen panel according to an embodiment of the present invention.
