Description

Technical field

[0001] The invention relates to a touch sensor. The invention relates in particular to a large-area touch sensor that can form a desired one-enlarged pattern area by stitching when a mat electrode connection wiring is provided to connect an intermediate one-joining pad. Prior technology

[0002] A smartphone or similar touch sensor is an input device for receiving touch commands. According to the sensing methods of touch parts, there are currently resistive, capacitive, ultrasonic, and infrared. Capacitive is for the most recently used mainstream.

[0003] Capacitive uses a transparent substrate on which a conductive thin film is formed. In the capacitive type, the voltage at the contact surface changes when the user touches the surface of the transparent substrate that maintains a specific amount of voltage on the surface of the transparent substrate. The capacitive type detects changes in voltage to sense whether it is being touched.

[0004] The touch sensor includes several sensing units configured in the X and Y axes directions on a transparent substrate to determine the contact position accurately. The sensing units are classified into the first sensing electrode and the second sensing electrode, the first sensing electrode is configured and connected in the X-axis direction, and the second sensing electrode is configured and connected in the Y-axis direction. The first and second sensing electrodes may be connected to the first and second wiring portions respectively.

[0005] The first and second wiring portions may be extended along the side edges of the transparent substrate to connect to pad electrodes formed at the edge of the transparent substrate. The pad electrodes can be connected to the solder pad of a flexible printed circuit board (FPCB).

[0006] Patent Registration No. 1068285 discloses "LCD Exposure Mask Patterns and Methods Used for Exposure." Patent Registration No. 1068285 presents a method for improving stitching defects and image quality by resorting to utilizing lego pattern exposure in a subpixel or pixel unit of a liquid crystal display device.

[0007] However, the formation of a mat part in the middle region of the repetitive section is difficult to apply a conventional exposure mask. In particular, the reality of increased demand for elongated displays in one direction is difficult to cope with. Invention content

[0008] Technical issues

[0009] This invention addresses the problems of the prior art and aims to provide a large-area touch sensor. This large-area touch sensor can be manufactured by freely adjusting (enlarging) the pattern area using a stitching method when configuring pad electrode connection wiring to connect to a pad component in the middle region of the long side of a rectangular touch sensor. The pad component is also known as a bonding pad. Technical solution

[0010] To achieve this objective, a touch sensor of the present invention may include a non-repeating pattern portion, a first sensing unit portion, and a first wiring portion.

[0011] The first sensing unit can be configured by repeatedly arranging a first sensing unit line group in a first repetition number, such that it is separated in an X-axis direction, which is perpendicular to a Y-axis direction. The first sensing unit line group consists of several sensing units arranged and connected in the Y-axis direction.

[0012] The first wiring section may be formed in an outer frame region along a Y-axis direction from the first sensing unit section. The first wiring section may include a first outgoing wire group and a first dummy wire group.

[0013] The first output group may be provided with several first outputs, the number of which is the same as the number of first outgoing lines, the number of first outgoing lines corresponding to the number of first repetitions. One end of each of these first outputs is connected to the first sensing unit line group.

[0014] The first dummy line group may have several first dummy lines, the number of which is the same as the number of first dummy lines. One end of each of these first dummy lines is not connected to the first sensing unit line group.

[0015] These first outgoing lines and several other ends of these first dummy lines can be connected to a pad electrode.

[0016] The touch sensor of the present invention may include a first repeating pattern portion, a second sensing unit line group, and a second wiring portion.

[0017] The second sensing unit line group may be provided with several sensing units that are partially spaced from the first sensing unit in the -X axis direction, so as to be arranged and connected in a row in the Y axis direction.

[0018] The second wiring portion may be formed in the outer frame region along a direction formed by the second sensing unit line group and the first wiring portion. The second wiring portion may include a second outgoing line and a second dummy line group.

[0019] One end of the second output line can be connected to the second sensing unit line group.

[0020] The second dummy line group can be composed of several second dummy lines, the number of which is the same as the number of a second dummy line. One end of each of these second dummy lines is not connected to the second sensing unit line group.

[0021] The second outgoing line and the second dummy line group can be connected to these first dummy lines of the first dummy line group oriented in the -X axis direction.

[0022] In the touch sensor of the present invention, the second sensing unit line group and the second wiring portion can be repeatedly formed in the -X axis direction as many times as a second repetition number of two or more. In this case, the second dummy line group may include a number of these second dummy lines that is one less than the second repetition number.

[0023] The touch sensor of the present invention may include a second repeating pattern portion, a third sensing unit line group, and a third wiring portion.

[0024] The third sensing unit line group may be provided with several sensing units that are partially spaced from the first sensing unit in the +X axis direction, so as to be arranged and connected in a row in the Y axis direction.

[0025] The third wiring section may be formed in the outer frame region along a direction formed by the third sensing unit line group and the first wiring section. The third wiring section may include a third outgoing line and a third dummy line group.

[0026] One end of the third output line can be connected to the third sensing unit line group.

[0027] The third dummy line group can be composed of several third dummy lines, the number of which is the same as the number of third dummy lines. One end of each of these third dummy lines is not connected to the third sensing unit line group.

[0028] The third outgoing line and the third dummy line group can be connected to these first dummy lines of the first dummy line group oriented in the +X axis direction.

[0029] In the touch sensor of the present invention, the third sensing unit line group and the third wiring portion can be repeatedly formed in the +X axis direction as many times as a third repetition number of two or more. In this case, the third dummy line group may include a number of these third dummy lines that is one less than the third repetition number.

[0030] In the touch sensor of the present invention, the first dummy line group may include the same number of these first dummy lines as there is a number corresponding to the sum of one of the second and third repetition numbers.

[0031] In the touch sensor of the present invention, the non-repeating pattern portion, the first repeating pattern portion, and the second repeating pattern portion can be repeatedly formed along the X-axis in the same shape.

[0032] In the touch sensor of the present invention, the non-repeating pattern portion may have a symmetrical structure along the X-axis.

[0033] In the touch sensor of the present invention, the non-repeating pattern portion may have an asymmetric structure along the X-axis.

[0034] In the touch sensor of the present invention, the first repeating pattern portion and the second repeating pattern portion may have a symmetrical structure around the non-repeating pattern portion.

[0035] In the touch sensor of the present invention, the first repeating pattern portion and the second repeating pattern portion may have an asymmetrical structure surrounding the non-repeating pattern portion. Beneficial effects

[0036] The touch sensor of this invention, having this assembly, allows for free adjustment (increasing) of the length of the long side of the patterned area by applying a splicing method when configuring pad electrode connection wiring to connect to the pad component on the long side. The pad component is also known as the bonding pad. In this way, the touch sensor of this invention simplifies the manufacture of large rectangular touch sensors, which are used in narrow, elongated display devices. To provide a better understanding of the above and other aspects of this invention, specific embodiments are described below in conjunction with the accompanying drawings: Simple Explanation of the Diagram

[0037] Figure 1 shows a plan view of a touch sensor according to a first embodiment of the present invention. Figure 2 shows a plan view of a touch sensor according to a second embodiment of the present invention. Figure 3 shows a plan view of a touch sensor according to a third embodiment of the present invention. Figure 4 illustrates a schematic diagram of an example of an exposure mask used to manufacture a touch sensor according to a first embodiment of the present invention using spliced ​​exposures. Implementation

[0038] The present invention will be described in more detail here with reference to the drawings.

[0039] Figure 1 shows a plan view of a touch sensor according to a first embodiment of the present invention.

[0040] As shown in Figure 1, the touch sensor of the first embodiment may include a non-repeating pattern portion A, a first repeating pattern portion B1, a second repeating pattern portion C1, etc.

[0041] The non-repeating pattern section A forms an area, which may include a first sensing unit section S1, a first wiring section L1, etc. A bonding pad is connected to one side of the area to a flexible printed circuit board (FPCB) (not shown).

[0042] The first sensing unit S1 generates a sensing signal when it senses an external touch, and may include several sensing unit groups, which are composed of several sensing units. Each sensing unit group may include one or more Y-axis sensing unit line groups and one or more X-axis sensing unit line groups. The Y-axis sensing unit line group is composed of several sensing units arranged and connected in the Y-axis direction (upper and lower in Figure 1). The X-axis sensing unit line group is composed of several sensing units arranged and connected in the X-axis direction (left and right in Figure 1). The X-axis direction is perpendicular to the Y-axis direction.

[0043] The Y-axis sensing unit line group can be configured to have the same number of repetitions as the first set (4 in Figure 1) when separated along the X-axis direction. The sensing units of the Y-axis sensing unit line group can be integrally connected along the Y-axis direction.

[0044] The X-axis sensing unit line group can be configured with several units when separated along the Y-axis direction (four in Figure 1). The sensing units of the X-axis sensing unit line group can be connected along the X-axis direction via conductive bridges or similar means.

[0045] The sensing unit can be assembled in the form of an island. The sensing unit can be composed of a transparent conductive oxide, such as indium tin oxide (ITO), indium zinc oxide (IZO), aluminum zinc oxide (AZO), zinc oxide (ZnO x), titanium oxide (TiO 2), or aluminum oxide (Al 2O 3). Alternatively, indium zinc tin oxide (IZTO), indium oxide (InO x), tin oxide (SnO x), cadmium tin oxide (CTO), gallium-doped zinc oxide (GZO), zinc tin oxide (ZTO), indium gallium oxide (IGO), or similar materials, or combinations thereof, can be used. The sensing unit can be composed of conductive metals, alloys, or a multilayer structure including metals. In addition, the sensing unit can be in the form of a mesh or something similar that can increase light transmittance.

[0046] The first wiring portion L1 connects the sensing unit and the external device to transmit sensing signals. An example of the external device is a pad electrode. The first wiring portion L1 may be formed in the outer frame region (lower side in Figure 1) along the Y-axis direction from the first sensing unit portion S1. The first wiring portion L1 may be composed of a conductive metal, such as silver (Ag), gold (Au), copper (Cu), aluminum (Al), platinum (Pt), palladium (Pd), chromium (Cr), titanium (Ti), tungsten (W), niobium (Nb), tantalum (Ta), vanadium (V), iron (Fe), manganese (Mn), cobalt (Co), nickel (Ni), zinc (Zn), or alloys thereof (e.g., silver-palladium-copper, APC).

[0047] The first wiring section L1 may include a first outgoing line group L11 and a first dummy line group L12 and L13.

[0048] The first output group L11 has one end (at the top in Figure 1) connected to the outermost sensing unit (at the bottommost in Figure 1) of the Y-axis sensing unit line group. The first output group L11 may include as many first output lines as the first repetition number (4 in Figure 1) (the four lines in the frame of the first output group L11 in Figure 1). The first repetition number corresponds to the first outward number (4 in Figure 1).

[0049] The first dummy line groups L12 and L13 can be composed of the same number of first dummy lines as the first dummy number (in Figure 1, five first dummy lines are in the frame of the first dummy line group L12 and five first dummy lines are in the frame of the first dummy line group L13). One end of the first dummy line (the end in the -X-axis direction and the +X-axis direction in Figure 1) is not connected to the outermost sensing unit (the bottommost sensing unit in Figure 1) of the Y-axis sensing unit line group. Here, the number of first dummy lines is determined according to the number of repetitions in the X-axis direction of the Y-axis sensing unit line groups formed in the first repeating pattern section B1 and the second repeating pattern section C1. For example, when five of the first repeating pattern sections B1 (B1 to B5) are formed in the -X-axis direction, the first dummy line group L12 with five first dummy lines is formed in the direction of the first repeating pattern section B1 (the -X-axis direction). When five of the repeating pattern portions C1 (C1 to C5) are formed in the +X axis direction, a first dummy line group L13 with five first dummy lines is formed in the direction of the second repeating pattern portion C1 (+X axis direction). Then, the number of first dummy lines is 10, and a total of 10 first dummy lines can be formed. That is, the first dummy lines of the first dummy line groups L12 and L13 connect each Y-axis sensing unit line group formed in the repeating patterns B1 to B5 of the first repeating pattern portion B1 and the repeating patterns C1 to C5 of the second repeating pattern portion C1 to an external device (e.g., an FPCB), and can form at least the number of repetitions of the first repeating pattern portion B1 and the second repeating pattern portion C1.

[0050] In the first dummy line groups L12 and L13, these first dummy lines can be sequentially connected to the Y-axis sensing unit line groups that are moved outward (in the -X-axis direction or +X-axis direction) from the first repeating pattern section B1 and the second repeating pattern section C1, respectively, away from the first sensing unit section S1 (downward in the first figure).

[0051] The other end of the first outgoing line and the first dummy line (in the lower part of Figure 1) can be connected to an external device, such as the bonding pad of the FPCB via the pad electrode.

[0052] The first repeating pattern section B1 is formed in one of the X-axis directions (to the left in Figure 1, that is, the -X-axis direction) in a manner separated from the non-repeating pattern section A, and may include the second sensing unit section S2, the second wiring section L2, etc.

[0053] The second sensing unit S2 generates a sensing signal when it senses an external touch, and may include several sensing units. These sensing units include a Y-axis sensing unit line group and one or more X-axis sensing unit line groups. The Y-axis sensing unit line group is arranged in the Y-axis direction (upper and lower in Figure 1), and the X-axis sensing unit line group is arranged in the X-axis direction (left and right in Figure 1). The X-axis direction is perpendicular to the Y-axis direction.

[0054] The sensing units of the Y-axis sensing unit assembly can be connected as a single unit along the Y-axis direction.

[0055] The X-axis sensing unit line group can be configured with several units when separated along the Y-axis direction (four in Figure 1). The sensing units of the X-axis sensing unit line group can be connected along the X-axis direction via conductive bridges or similar means.

[0056] The sensing unit can be assembled into an island and can be made of the aforementioned transparent conductive oxide or similar materials.

[0057] The second wiring section L2 may include a second outgoing line L21 and a second dummy line group L22.

[0058] The second output line L21 may have one end (the upper left side in Figure 1) and the other end (the right end in Figure 1). This end (the upper left side in Figure 1) is connected to the outermost sensing unit (the lowermost sensing unit in Figure 1) of the Y-axis sensing unit line group. The other end (the right end in Figure 1) is connected to one end of a first dummy line (the left end in Figure 1). This first dummy line is the innermost first dummy line (closest to the first output line group L11 in Figure 1) in the direction of the second wiring section L2 (to the left in Figure 1, that is, the -X-axis direction) formed in the first dummy line groups L12 and L13 of the non-repeating pattern section A.

[0059] The second dummy line group L22 may include a second dummy line, one end of which (the left end in Figure 1) is connected to the outermost sensing unit (the bottommost sensing unit in Figure 1) of the Y-axis sensing unit line group in the first repeating pattern section B1, not connected to it. The number of second dummy lines may be the same as the number of second dummy lines (4 in Figure 1). The number of second dummy lines may correspond to the number of times the first repeating pattern section B1 is repeatedly formed outside of the first repeating pattern section B1 (on the left side in Figure 1, i.e., in the -X-axis direction). For example, if the first repeating pattern section B1 is additionally repeated four times (B2 to B5) outside of the first repeating pattern section B1 (in the -X-axis direction in Figure 1), the number of second dummy lines included in the second dummy line group L22 may be four. In this way, the second sensing unit section S2 and the second wiring section L2 may be repeated in the -X-axis direction (on the left side in Figure 1) as many times as the number of second repetitions (5 in Figure 1). In this case, the second dummy line group L22 may include a number (4) of second dummy lines that is one less than the second number of repetitions (5 in the first figure).

[0060] In the second dummy line group L22, one end of the innermost second dummy line (the uppermost one in Figure 1) of the four second dummy lines (the left end in Figure 1) can be connected to the outer end of the second line L21 of the second repeating pattern section B2 (the lower right end in Figure 1), and the other end (the right end in Figure 1) can be connected to one end of the first dummy line in the first dummy line group L12 formed from the inside in the non-repeating pattern section A along the direction of the second wiring section L2 (in the -X axis direction in Figure 1, that is, the left end).

[0061] In the second dummy line group L22, the second dummy lines can be arranged in a manner that has the same shape and can be separated from each other by the same interval.

[0062] The second repeating pattern section C1 is formed in another direction of the X-axis (on the right side of Figure 1, that is, the +X-axis direction) in a manner separated from the non-repeating pattern section A, and may include the third sensing unit section S3, the third wiring section L3, etc.

[0063] The third sensing unit S3 generates a sensing signal when it senses an external touch, and may include several sensing units. These sensing units may include a Y-axis sensing unit line group and one or more X-axis sensing unit line groups. The Y-axis sensing unit line group is arranged in the Y-axis direction (upper and lower in Figure 1), and the X-axis sensing unit line group is arranged in the X-axis direction (left and right in Figure 1). The X-axis direction is perpendicular to the Y-axis direction.

[0064] The sensing units of the Y-axis sensing unit assembly can be connected as a single unit along the Y-axis direction.

[0065] The X-axis sensing unit line group can be configured with several units when separated along the Y-axis direction (four in Figure 1). The sensing units of the X-axis sensing unit line group can be connected along the X-axis direction via conductive bridges or similar means.

[0066] The sensing unit can be assembled into an island and can be made of the aforementioned transparent conductive oxide or similar materials.

[0067] The third wiring section L3 may include the third outgoing line L31 and the third dummy line group L32.

[0068] The third output line L31 may have one end (the upper right side in Figure 1) and the other end (the left end in Figure 1). This end (the upper right side in Figure 1) is connected to the outermost sensing unit (the lowermost sensing unit in Figure 1) of the Y-axis sensing unit line group. The other end (the left end in Figure 1) is connected to one end (the right end in Figure 1) of a first dummy line. This first dummy line is the innermost first dummy line (closest to the first output line group L11 in Figure 1) in the direction of the third wiring section L3 (the right side in Figure 1, i.e., the +X axis direction) formed in the first dummy line groups L12 and L13 of the non-repeating pattern section A.

[0069] The third dummy line group L32 may include a third dummy line, one end of which (the right end in Figure 1) is connected to the outermost sensing unit (the bottommost sensing unit in Figure 1) of the Y-axis sensing unit line group in the second repeating pattern section C1, which is not connected to it. The number of third dummy lines may be the same as the number of third dummy lines (4 in Figure 1). The number of third dummy lines may correspond to the number of times the second repeating pattern section C1 is repeatedly formed outside the second repeating pattern section C1 (the right side in Figure 1, that is, in the +X axis direction). For example, if the second repeating pattern section C1 is additionally repeated four times (C2 to C5) outside the second repeating pattern section C1 (in the +X axis direction in Figure 1), the number of third dummy lines included in the third dummy line group L32 may be four. In this way, the third sensing unit section S3 and the third wiring section L3 may be repeated in the +X axis direction (the right side in Figure 1) as many times as the number of third repetitions (5 in Figure 1). In this case, the third dummy line group L32 may include a number (4) of third dummy lines that is one less than the third number of repetitions (5 in Figure 1).

[0070] In the third dummy line group L32, one end of the innermost third dummy line (the uppermost one in Figure 1) of the four third dummy lines (the right end in Figure 1) can be connected to the outer end of the third line L31 of the second repeating pattern section C2 (the lower left end in Figure 1), and the other end (the left end in Figure 1) can be connected to one end of the first dummy line in the first dummy line group L13 formed from the inside in the non-repeating pattern section A along the direction of the third wiring section L3 (in the +X axis direction in Figure 1, that is, the right end).

[0071] In the third dummy line group L32, the third dummy lines can be arranged in a manner that has the same shape and can be separated from each other by the same interval.

[0072] In the touch sensor of the first embodiment, as shown in Figure 1, the first repeating pattern portion B1 can be repeatedly formed in the same shape (B2 to B5) on the outer side of the first repeating pattern portion B1 (upper left side in Figure 1, i.e., the -X-axis direction), and the second repeating pattern portion C1 can also be repeatedly formed in the same shape (C2 to C5) on the outer side of the second repeating pattern portion C1 (upper right side in Figure 1, i.e., the +X-axis direction). The number of first and second repetitions can be selected according to the length of the long side.

[0073] The touch sensor of the first embodiment can repeatedly form a combination of non-repeating pattern portion A, repeating patterns B1 to B5 of the first repeating pattern portion B1, and repeating patterns C1 to C5 of the second repeating pattern portion C1 along the X-axis.

[0074] As shown in Figure 1, the touch sensor of the first embodiment can form a non-repeating pattern portion A, namely the first sensing unit portion S1 and the first wiring portion L1, symmetrically along the X-axis (that is, left and right).

[0075] Furthermore, as shown in Figure 1, the touch sensor of the first embodiment can form repeating patterns B1 to B5 of the first repeating pattern portion B1 and repeating patterns C1 to C5 of the second repeating pattern portion C1 around the non-repeating pattern portion A along the X-axis (that is, left and right).

[0076] Furthermore, the touch sensor of the first embodiment may form a wiring portion. The wiring portion is connected to one or more X-axis sensing unit line groups. These one or more X-axis sensing unit line groups are arranged and connected along the X-axis (left and right in the first figure), and are separated along the Y-axis (up and down in the first figure) at one end in the X-axis direction, that is, at least one of the outer frame regions at the left and right ends.

[0077] Figure 2 shows a plan view of a touch sensor according to a second embodiment of the present invention.

[0078] The touch sensor of the second embodiment forms a non-repeating pattern portion A', which is the first sensing unit portion and the first wiring portion, asymmetrically along the X-axis (that is, left and right).

[0079] As shown in Figure 2, three Y-axis sensing unit line groups can be formed in the first sensing unit section. In this case, three (odd number) outgoing lines are formed in the first wiring section, resulting in asymmetrical outgoing lines. In this way, even if the repeating patterns B1 to B5 of the first repeating pattern section B1 and the repeating patterns C1 to C5 of the second repeating pattern section C1 are symmetrically formed on either side of the non-repeating pattern section A' in the X-axis direction (with the same number of repetitions), either side of the first dummy line group in the X-axis direction (i.e., left and right) of the non-repeating pattern section A' can have a different shape relative to the Y-axis.

[0080] Figure 3 shows a plan view of a touch sensor according to a third embodiment of the present invention.

[0081] In the touch sensor of the third embodiment, as shown in Figure 3, the number of repetitions of the first repeating pattern portion B1 and the second repeating pattern portion C1 can differ among the repeating patterns B1 to B5 of the first repeating pattern portion B1 and the repeating patterns C1 to C4 of the second repeating pattern portion C1. In this case, the X-axis (i.e., left and right) width (or the number of repetitions of the Y-axis sensing unit line groups) of the repeating patterns B1 to B5 of the first repeating pattern portion B1 and the repeating patterns C1 to C4 of the second repeating pattern portion C1 around the non-repeting pattern portion A can become different. As a result, the number of dummy lines in the second dummy line group of the first repeating pattern portion B1 and the third dummy line group of the second repeating pattern portion C1 becomes different, causing the repeating patterns B1 to B5 of the first repeating pattern portion B1 and the repeating patterns C1 to C4 of the second repeating pattern portion C1 to present an asymmetry along the X-axis (i.e., left and right) around the non-repeting pattern portion A.

[0082] Figure 4 illustrates a schematic diagram of an example of an exposure mask used to manufacture a touch sensor according to a first embodiment of the present invention using spliced ​​exposures.

[0083] As shown in Figure 4, the exposure mask used to manufacture the touch sensor of the first embodiment can be assembled to separate or integrate the non-repeating pattern portion A, the first repeating pattern portion B1, the second repeating pattern portion C1, etc. The non-repeating pattern portion A, the first repeating pattern portion B1, and the second repeating pattern portion C1 can be exposed separately for each region, and can have overlapping areas at the boundaries of the regions.

[0084] In the case where the exposure mask system is integrally formed, when the first repeating pattern portion B1 or the second repeating pattern portion C1 is repeatedly exposed, the non-repeating pattern portion A and the second repeating pattern portion C1, or the non-repeating pattern portion A and the first repeating pattern portion B1, can approach (cover) each other to repeatedly expose the first repeating pattern portion B1 or the second repeating pattern portion C1 respectively.

[0085] Exposure masks can be configured by assembling different mask patterns by separating the sensing unit and the outgoing lines. Depending on the structure and material of each layer, the different mask patterns are not integrated together. In this case, the areas of the non-repeating pattern part A, the first repeating pattern part B1, and the second repeating pattern part C1 can each have the same shape for each individual mask, and the number of repeating parts can be configured differently as needed.

[0086] While specific embodiments of the invention have been illustrated and described, it will be understood by those skilled in the art that it is not intended to limit the invention to the preferred embodiments, and that various changes and modifications may be made without departing from the spirit and scope of the invention, which will be obvious to those skilled in the art.

In summary, although the invention has been disclosed above by way of embodiments, it is not intended to limit the invention. Those skilled in the art to which this invention pertains may make various modifications and refinements without departing from the spirit and scope of the invention.
