[0001] Cross - reference to related applications

[0002] This application claims the benefit of priority to Korean Patent Application No. 10 - 2020 - 0184850, filed on December 28, 2020, with the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference. Technical field

[0003] The present invention relates to a touch display device. Background art

[0004] In addition to the function of displaying images or data, touch display devices increasingly adopt a touch - based input function, which enables users to easily input information or commands to the display device in an intuitive and simple manner.

[0005] To provide a touch - based input function, a touch display device needs to have the ability to accurately detect the presence of a touch from a user and detect the touch coordinates. For this purpose, the touch display device includes a touch panel having a touch sensor structure. Here, the touch sensor structure may include a plurality of touch electrodes and a plurality of touch lines.

[0006] As the size of the touch panel increases, the number of required touch electrodes also increases. As a result, the number of touch lines provided on the touch panel increases, and the number of touch channels (corresponding to the touch lines) of the touch driving circuit also needs to increase. This makes panel manufacturing more complex and increases the manufacturing cost. Correspondingly, the associated touch driving circuit can be more complex, and the manufacturing cost of the touch driving circuit can be further increased. Summary of the invention

[0096] The touch controller 300 can know the presence or absence of a touch and / or the touch coordinates (touch position) by using the sensing data received from the touch driving circuit 310.

[0097] The touch driving signal TDS may be a signal whose voltage level changes over time. In one embodiment, the touch driving signal TDS may have one or more of various signals such as a square wave, a triangular wave, a sine wave, etc.

In one embodiment, the touch electrode TE may be designed in various shapes, such as a rhombus, a long rectangle, etc. Although Figure 2BIt is shown that each touch electrode TE or the area occupied by each touch electrode TE has the same size and shape, which is only an example for convenience of description; the embodiments described herein are not limited thereto. In one embodiment, at least one of the one or more sizes and shapes of one or more touch electrodes TE or one or more areas occupied by one or more touch electrodes TE may be different from at least one of the one or more sizes and shapes of one or more other touch electrodes TE or one or more areas occupied by one or more other touch electrodes TE.

In another embodiment, as Figure 3 shown, the size of the area where one touch electrode TE is provided may be larger than the size of the area where one sub-pixel SP is provided.

[0115] When the size of the area where one touch electrode TE is provided is larger than the size of the area where two or more sub-pixels SP are provided, one touch electrode TE may overlap two or more data lines DL and two or more gate lines GL.

[0116] The touch driving circuit 310 and the touch controller 320 may be implemented as separate components or integrated into one component.

[0117] In one embodiment, the touch driving circuit 310 may be implemented as a readout IC, and the touch controller 320 may be implemented as a micro control unit MCU.

[0118] Meanwhile, the touch driving circuit 310 and the data driving circuit 220 may be integrated together and implemented as one integrated circuit chip. The driving circuit in which the touch driving circuit 310 and the data driving circuit 220 are integrated together may be implemented as one or more integrated circuit chips.

[0119] In one embodiment, the touch driving signal TDS may have one or more of various signals such as a square wave, a triangular wave, a sine wave, etc. In one embodiment, when a square wave touch driving signal TDS is adopted, such a touch driving signal TDS may be of the pulse width modulation (PWM) signal type.

[0120] Refer to Figure 3, one or more data lines DL and one or more gate lines GL may cross each other. That is, the data lines DL may extend in a first direction, and the gate lines GL may extend in a second direction different from the first direction.

[0121] For example, the first direction may be a vertical direction, and the second direction may be a horizontal direction. In another example, the first direction may be a horizontal direction, and the second direction may be a vertical direction.

[0122] The vertical direction and the horizontal direction described herein are only used to distinguish two different directions. The vertical direction and the horizontal direction are merely to represent two directions relative to each other, and they are interchangeable. That is, the vertical direction described below may be represented as a horizontal direction or other direction according to the viewing direction. Similarly, the horizontal direction described below may be represented as a vertical direction or other direction according to the viewing direction.

[0123] The vertical direction described herein may refer to the direction in which a data line DL is arranged (extends) in the touch display device, and the horizontal direction may refer to the direction in which a gate line GL is arranged (extends) in the touch display device.

[0124] Figure 4 Illustrates a part of an example split touch sensor structure in a touch display device 100 according to various aspects of the present invention.

[0125] Referring to Figure 4 , the touch panel TSP of the touch display device 100 according to various aspects of the present invention may include a plurality of touch electrodes TE as touch sensors, and the plurality of touch electrodes TE may be arranged to be separated from each other.

[0126] The plurality of touch electrodes TE are not only physically separated from each other but also electrically separated from each other. Such a touch sensor structure is called a split touch sensor structure. However, two or more or all of the plurality of touch electrodes TE may be electrically connected in the touch driving circuit 310.

[0127] In the case of the split touch sensor structure, each of the plurality of touch electrodes TE may be electrically connected to a touch line TL through one or more contact holes CNT.

[0128] The plurality of touch electrodes TE may be located in the display area DA. In some embodiments, one or more of the plurality of touch electrodes TE (e.g., one or more outermost touch electrodes) may be located in the edge area (outer edge) of the display area DA, or arranged to extend to the edge area (outer edge) of the display area DA. Here, the display area DA is an area for displaying an image and may be an area where touch sensing can be performed.

[0129] As Figure 4As shown, multiple touch lines TL electrically connected to multiple touch electrodes TE may be located in the display area DA. In some embodiments, one or more or all of the multiple touch lines TL may be located at the edge of the display area DA.

[0130] As Figure 4 shown, when multiple touch lines TL electrically connected to multiple touch electrodes TE are located in the display area DA, the multiple touch lines TL may be located in one or more layers different from the multiple touch electrodes TE and overlap with the multiple touch electrodes TE.

[0131] Referring Figure 4 , all the touch lines TL may have equal or similar lengths to each other. That is, the multiple touch lines TL may be set from the pad portion 400 connecting the touch driving circuit 310 to a position opposite to the pad portion 400, regardless of the position of the contact hole CNT.

[0132] In another embodiment, the length of each touch line TL may vary depending on the position of the touch electrode TE to which it is electrically connected. Therefore, the length of each touch line TL may be the distance from the pad portion 400 to the position where the corresponding contact hole CNT is located.

[0133] Referring Figure 4 , in the case of a segmented touch sensor structure, in a scheme where one touch electrode TE is electrically connected to one touch line TL, the number of the multiple touch lines TL needs to be the same as the number of the multiple touch electrodes. Here, the number of the multiple touch lines TL corresponds to the number of touch channels TCH for inputting / outputting signals to / from the touch driving circuit 310.

[0134] According Figure 4 to the shown, the segmented touch sensor structure may include 16 touch electrodes TE arranged in 4 rows and 4 columns, and include 16 touch lines TL for electrically connecting the 16 touch electrodes TE to the touch driving circuit 310. Therefore, the touch driving circuit 310 has 16 touch channels TCH.

[0135] In the case of a segmented touch sensor structure, the number of touch electrodes TE is a value obtained by multiplying the number of touch electrode rows by the number of touch electrode columns, and the number of touch lines TL and the number of touch channels TCH may be the same as the number of touch electrodes TE.

[0136] In the case of a segmented touch sensor structure, as the number of touch electrodes TE increases, the number of touch lines TL and the number of touch channels TCH may also increase.

[0137] When the size of the touch panel TSP increases or the number of touch electrodes TE increases to improve touch sensing accuracy, the number of touch lines TL increases, and the number of touch channels TCH of the touch driving circuit 310 also increases. As a result, the manufacturing of the panel becomes complex and difficult, and the internal circuit structure of the touch driving circuit 310 may become complex due to a large number of touch channels TCH.

[0138] Meanwhile, Figure 4 The split-type touch sensor structure shown may be a touch sensor for sensing a touch based on the self-capacitance of each touch electrode TE, or may be a touch sensor for sensing a touch based on the mutual capacitance between touch electrodes TE.

[0139] Figure 5 Illustrate a method for reducing the number of touch channels in the split-type touch sensor structure of the touch display device 100 according to various aspects of the present invention.

[0140] Referring to Figure 5 , in order to reduce the number of touch lines TL and the number of touch channels TCH, in the case of the split-type touch sensor structure, the size of the touch electrode TE can be increased.

[0141] According to Figure 5 As shown, by increasing the size of one touch electrode TE, the number of touch electrodes TE provided in the same area can be reduced from 16 to 9. Therefore, the number of touch lines TL and the number of touch channels TCH can also be reduced from 16 to 9.

[0142] As described above, by increasing the size of one touch electrode TE, the number of touch electrodes TE, the number of touch lines TL, and the number of touch channels TCH can also be reduced.

[0143] However, when the size of one touch electrode TE increases, the number of points for sensing capacitance changes in the same area can be reduced. That is, when the size of one touch electrode TE increases, the number of touch nodes corresponding to touch coordinates in the same area can be reduced from 16 to 9. Here, in the split-type touch sensor structure, one touch node can be one touch electrode TE.

[0144] Therefore, the accuracy of touch sensing may deteriorate. For example, when the size of the touch electrode increases, the touch sensing circuit 300 may not distinguish between two different touch positions.

[0145] Therefore, according to an embodiment of the present invention, a woven-type touch sensor structure is provided, which designs the number of touch nodes corresponding to touch coordinates to be equal to or close to Figure 4The number of touch nodes in the split-type touch sensor structure shown can reduce the number of touch lines TL and the number of touch channels TCH while maintaining touch sensing accuracy.

[0146] Figure 6 Illustrate an example touch sensor unit in the woven touch sensor structure of the touch display device 100 according to various aspects of the present invention.

[0147] Refer to Figure 6 In the touch display device 100 according to various aspects of the present invention, the basic unit of the woven touch sensor structure is referred to as a touch sensor unit TSU. That is, the woven touch sensor structure includes two or more touch sensor units TSU.

[0148] Here, it is assumed that the area occupied by one touch sensor unit TSU included in the woven touch sensor structure is the same as the area occupied by Figure 4 the split-type touch sensor structure.

[0149] Refer to Figure 6 Each touch sensor unit TSU may include four horizontal electrodes (H1 - H4) and four vertical electrodes (V1 - V4).

[0150] Although Figure 6 shows that in each touch sensor unit TSU, the four horizontal electrodes (H1 - H4) and the four vertical electrodes (V1 - V4) are arranged in a simple rectangular form, this electrode arrangement is only to simply present the arrangement structure of the four horizontal electrodes (H1 - H4) and the four vertical electrodes (V1 - V4) according to the woven touch sensor structure as an equivalent structure. Therefore, in actual implementation, the corresponding electrodes can be formed with a more complex arrangement. This will be described in more detail below.

[0151] Figure 7 Illustrate an example touch sensor unit TSU in the woven touch sensor structure of the touch display device 100 according to various aspects of the present invention.

[0152] Refer to Figure 7 According to various aspects of the present invention, a touch display device may have a woven touch sensor structure, which can reduce the number of touch lines TL and the number of touch channels TCH while maintaining touch sensing accuracy by designing the number of touch nodes corresponding to touch coordinates to be equal to or close to Figure 4 the number of touch nodes in the split-type touch sensor structure shown.

[0153] Here, "woven" may refer to the complex intertwining of electrodes (H1-H4, V1A-V1D, V2A-V2D, V3A-V3D, V4A-V4D).

[0154] Referring to Figure 7 , a touch sensor unit TSU having a woven touch sensor structure according to an embodiment of the present invention may include a first horizontal electrode H1, a second horizontal electrode H2, a third horizontal electrode H3, and a fourth horizontal electrode H4.

[0155] Each of the first horizontal electrode H1, the second horizontal electrode H2, the third horizontal electrode H3, and the fourth horizontal electrode H4 is arranged in the horizontal direction. Each of the first horizontal electrode H1, the second horizontal electrode H2, the third horizontal electrode H3, and the fourth horizontal electrode H4 is vertically separated from each other.

[0156] Referring to Figure 7 , in order to electrically connect the first horizontal electrode H1, the second horizontal electrode H2, the third horizontal electrode H3, and the fourth horizontal electrode H4 to the touch driving circuit 310, a touch sensor unit TSU having a woven touch sensor structure according to an embodiment of the present invention may further include a first horizontal touch line HTL1, a second horizontal touch line HTL2, a third horizontal touch line HTL3, and a fourth horizontal touch line HTL4.

[0158] Referring to Figure 7 , in order to form first to fourth vertical electrodes (V1-V4) using the separation electrodes (V1A-V1D, V2A-V2D, V3A-V3D, V4A-V4D), a touch sensor unit TSU having a woven touch sensor structure according to an embodiment of the present invention may include: a first vertical touch line VTL1, a second vertical touch line VTL2, a third vertical touch line VTL3, and a fourth vertical touch line VTL4.

[0159] The first vertical touch line VTL1 can be electrically connected to the first separated electrode V1A in the first column, the second separated electrode V2A in the first column, the third separated electrode V3A in the first column, and the fourth separated electrode V4A in the first column. Thus, these separated electrodes (V1A-V4A) can be electrically connected to the touch driving circuit 310 together or simultaneously.

[0160] The first separated electrode V1A in the first column, the second separated electrode V2A in the first column, the third separated electrode V3A in the first column, and the fourth separated electrode V4A in the first column are included in the first vertical electrode V1.

[0161] The second vertical touch line VTL2 can be electrically connected to the first separated electrode V1B in the second column, the second separated electrode V2B in the second column, the third separated electrode V3B in the second column, and the fourth separated electrode V4B in the second column. Thus, these separated electrodes (V1B-V4B) can be electrically connected to the touch driving circuit 310 together or simultaneously.

[0162] The first separated electrode V1B in the second column, the second separated electrode V2B in the second column, the third separated electrode V3B in the second column, and the fourth separated electrode V4B in the second column are included in the second vertical electrode V2.

[0163] The third vertical touch line VTL3 can be electrically connected to the first separated electrode V1C in the third column, the second separated electrode V2C in the third column, the third separated electrode V3C in the third column, and the fourth separated electrode V4C in the third column. Thus, these separated electrodes (V1C-V4C) can be electrically connected to the touch driving circuit 310 together or simultaneously.

[0164] The first separated electrode V1C in the third column, the second separated electrode V2C in the third column, the third separated electrode V3C in the third column, and the fourth separated electrode V4C in the third column are included in the third vertical electrode V3.

[0165] The fourth vertical touch line VTL4 can be electrically connected to the first separated electrode V1D in the fourth column, the second separated electrode V2D in the fourth column, the third separated electrode V3D in the fourth column, and the fourth separated electrode V4D in the fourth column. Thus, these separated electrodes (V1D-V4D) can be electrically connected to the touch driving circuit 310 together or simultaneously.

[0166] The first partition electrode V1D in the fourth column, the second partition electrode V2D in the fourth column, the third partition electrode V3D in the fourth column, and the fourth partition electrode V4D in the fourth column are included in the fourth vertical electrode V4.

[0167] For a woven touch sensor structure according to an embodiment of the present invention, in a touch sensor unit TSU that occupies the same area as the Figure 4 split touch sensor structure, four horizontal electrodes (H1 - H4) and four vertical electrodes (V1 - V4) can be provided, thereby forming a total of 16 touch nodes. Here, in the woven touch sensor structure, a touch node refers to an area where one horizontal electrode and one vertical electrode cross each other.

[0168] A touch sensor unit TSU having a woven touch sensor structure according to an embodiment of the present invention may include four horizontal touch lines (HTL1 - HTL4) and four vertical touch lines (VTL1 - VTL4), thus requiring a total of eight touch lines TL. Therefore, the number of touch lines TL required in the woven touch sensor structure can be reduced to half of the number of touch lines TL (16) required in the Figure 4 split touch sensor structure.

[0169] Therefore, the woven touch sensor structure according to an embodiment of the present invention can maintain the same number of touch nodes as the Figure 4 split touch sensor structure, thereby being able to reduce the number of touch lines TL and the number of touch channels TCH while maintaining touch sensing accuracy.

[0170] Meanwhile, in the Figure 7 shown woven touch sensor structure, the horizontal electrodes (H1 - H4) can be set parallel to the gate lines GL. Therefore, the overlapping area between one horizontal electrode (one of H1 - H4) and one gate line GL becomes larger.

[0171] As a result, as the overlapping area between the horizontal electrodes (H1 - H4) corresponding to the touch electrode TE and the gate lines GL increases, the parasitic capacitance between the touch electrode TE and the gate lines GL can become larger, which can lead to poor touch sensitivity.

[0172] The following describes a modified woven touch sensor structure that can reduce the parasitic capacitance between the touch electrode TE and the gate lines GL while maintaining the Figure 7 advantages of the woven touch sensor structure.

[0209] The fourth vertical touch line VTL4 may overlap with the second bridging portion HB2 of the second horizontal electrode H2 between the first separation electrode V1D located in the fourth column and the second separation electrode V2D located in the fourth column.

[0210] Reference Figure 8 , the plurality of gate lines GL are signal lines for transmitting gate signals to the plurality of sub-pixels SP for display driving, and are separated from each other in the vertical direction. Each of the plurality of gate lines GL may be set to extend in the horizontal direction.

[0211] In Figure 8 the case of the woven touch sensor structure, due to the shape of each of the first to fourth horizontal electrodes (H1 - H4), the overlapping area between the first to fourth horizontal electrodes (H1 - H4) and the gate line GL can be reduced.

[0212] For example, the plurality of gate lines GL may include a gate line GL that overlaps only with the plurality of first electrode portions HE1 of the first horizontal electrode H1 and does not overlap with the plurality of first bridging portions HB1 of the first horizontal electrode H1. Since such a gate line GL does not overlap with the plurality of first bridging portions HB1 of the first horizontal electrode H1, the overlapping area with the first horizontal electrode H1 can be reduced.

[0213] As a result, the parasitic capacitance between the first to fourth horizontal electrodes (H1 - H4) and the gate line GL can be reduced.

[0214] In Figure 8 the case of the woven touch sensor structure, since each of the first to fourth vertical electrodes (V1 - V4) includes a plurality of separation electrodes, the number of gate lines GL overlapping with each of the first to fourth vertical electrodes (V1 - V4) can be reduced.

[0215] As a result, the parasitic capacitance between the first to fourth vertical electrodes (V1-V4) and the gate line GL can be reduced.

[0216] As described above, in Figure 8 the case of the braided touch sensor structure, since the parasitic capacitance between the first to fourth horizontal electrodes (H1-H4) and the gate line GL can be reduced, and the parasitic capacitance between the first to fourth vertical electrodes (V1-V4) and the gate line GL can be reduced, the touch sensitivity can be significantly improved.

[0217] Referring to Figure 8 , the plurality of data lines DL are signal lines for transmitting image signals to the plurality of sub-pixels SP for display driving, and are separated from each other in the horizontal direction. Each of the plurality of data lines DL can be set to extend in the vertical direction.

[0218] The first horizontal touch line HTL1, the second horizontal touch line HTL2, the third horizontal touch line HTL3, the first vertical touch line VTL1, the second vertical touch line VTL2, etc. can be set to be parallel to the data line DL. The fourth horizontal touch line HTL4, the third vertical touch line VTL3, and the fourth vertical touch line VTL4 can also be set to be parallel to the plurality of data lines DL.

[0219] In Figure 8 the case of the braided touch sensor structure, at least one of the first to fourth horizontal electrodes (H1-H4) does not completely overlap a data line DL. As a result, the parasitic capacitance between the first to fourth horizontal electrodes (H1-H4) and the data line DL can be reduced.

[0220] In Figure 8 the case of the braided touch sensor structure, since each of the first to fourth vertical electrodes (V1-V4) includes a plurality of separated electrodes, the overlapping area of each of the first to fourth vertical electrodes (V1-V4) with a data line DL can be reduced. As a result, the parasitic capacitance between the first to fourth vertical electrodes (V1-V4) and the data line DL can be reduced.

[0221] As described above, in Figure 8 the case of the braided touch sensor structure, since the parasitic capacitance between the touch electrodes (H1-H4 and V1-V4) and the display driving lines (GL and DL) can be reduced, the touch sensitivity can be significantly improved.

[0222] In the woven touch sensor structure according to an embodiment of the present invention, each of the first horizontal electrode H1, the second horizontal electrode H2, the third horizontal electrode H3, the plurality of first partition electrodes (V1A, V1B, V1C, and V1D), and the plurality of second partition electrodes (V2A, V2B, V2C, and V2D) may be formed such that one or more first layer electrodes L1E and one or more second layer electrodes L2E are located in different layers and are arranged to be electrically connected to each other.

[0223] Referring to Figure 9 , each of the second electrode portion HE2 of the second horizontal electrode H2, the second bridging portion HB2 of the second horizontal electrode H2, the first partition electrode V1B in the second column, and the second partition electrode V2B in the second column may include a first layer electrode L1E and a second layer electrode L2E electrically separated by an insulating layer INS.

[0224] At this point, even though each of the second electrode portion HE2 and the second bridging portion HB2 of the second horizontal electrode H2 includes a first layer electrode L1E and a second layer electrode L2E located in different layers, in the region of the second horizontal electrode H2, the first layer electrode L1E and the second layer electrode L2E included in each of the second electrode portion HE2 and the second bridging portion HB2 may be electrically connected to each other at at least one point through a contact hole in the insulating layer INS.

[0225] Even when each of the first partition electrode V1B in the second column and the second partition electrode V2B in the second column, which are partition electrodes included in the second vertical electrode V2, includes a first layer electrode L1E and a second layer electrode L2E located in different layers, in the region of the first partition electrode V1B in the second column, the first layer electrode L1E and the second layer electrode L2E included in the first partition electrode V1B may be electrically connected at at least one point through a contact hole in the insulating layer INS, and in the region of the second partition electrode V2B in the second column, the first layer electrode L1E and the second layer electrode L2E included in the second partition electrode V2B may be electrically connected at at least one point through a contact hole in the insulating layer INS. The contact structure in the electrode regions of the above first layer electrode L1E and second layer electrode L2E may be basically equivalently applied to Figure 11 , 13 and 15.

[0226] Meanwhile, the second layer electrodes L2E included in the second electrode portion HE2 and the second bridging portion HB2 included in the second horizontal electrode H2, and the second layer electrodes L2E included in the first partition electrode V1B and the second partition electrode V2B included in the second vertical electrode V2 may be formed of the same material and located in the same layer. For the purpose of distinguishing each other in the figure and facilitating description, in Figure 9are displayed in different colors (brightness). This presentation of the second layer electrode L2E in the figure is equivalently applied to the Figure 11 , 13 and 15.

[0227] For example, the first layer electrode L1E may include the same material as the pixel electrode provided in the sub-pixel SP. The second layer electrode L2E may include the same material as the gate or gate line GL of the transistor in the sub-pixel SP.

[0241] In this case, a first horizontal touch line HTL1 may overlap with a first electrode part HE1, and may also overlap with a second electrode part HE2, a third electrode part HE3, and a fourth electrode part HE4 that overlap with the first vertical touch line VTL1. The first horizontal touch line HTL1 may be electrically connected to the first electrode part HE1 while being electrically separated from the second electrode part HE2, the third electrode part HE3, and the fourth electrode part HE4 that overlap with the first vertical touch line VTL1.

[0242] In another embodiment, a first vertical touch line VTL1 may overlap with a first electrode part HE1, a second electrode part HE2, a third electrode part HE3, and a fourth electrode part HE4 located in the same column, and may be electrically separated from the overlapping first to fourth electrode parts (HE1, HE2, HE3, and HE4).

[0246] In this case, a second horizontal touch line HTL2 may overlap with the second electrode portion HE2, and may also overlap with the third electrode portion HE3 and the fourth electrode portion HE4 that overlap with the second vertical touch line VTL2. The second horizontal touch line HTL2 may be electrically connected to the second electrode portion HE2 while being electrically separated from the third electrode portion HE3 and the fourth electrode portion HE4 that overlap with the first vertical touch line VTL1.

[0247] In another embodiment, the second vertical touch line VTL2 may overlap with a first electrode portion HE1, a second electrode portion HE2, a third electrode portion HE3, and a fourth electrode portion HE4 located in the same column, and is electrically separated from the overlapping first to fourth electrode portions (HE1, HE2, HE3, and HE4).

[0248] In this case, the second horizontal touch line HTL2 may overlap with the first electrode portion HE1, the second electrode portion HE2, the third electrode portion HE3, and the fourth electrode portion HE4 that overlap with the second vertical touch line VTL2. The second horizontal touch line HTL2 may overlap with the second electrode portion HE2 among the first electrode portion HE1, the second electrode portion HE2, the third electrode portion HE3, and the fourth electrode portion HE4 that overlap with the second vertical touch line VTL2, and is electrically separated from the first electrode portion HE1, the third electrode portion HE3, and the fourth electrode portion HE4.

[0249] In a touch sensor unit TSU having a woven touch sensor structure according to an embodiment of the present invention, a third vertical touch line VTL3 may overlap with a second electrode portion HE2 and a third electrode portion HE3 located in the same column, and may not overlap with a first bridging portion HB1, a second bridging portion HB2, and a third bridging portion HB3 located in the same column.

[0250] The third vertical touch line VTL3 may overlap with a second electrode portion HE2, a third electrode portion HE3, and a fourth electrode portion HE4 located in the same column, and is electrically separated from the second to fourth electrode portions (HE2, HE3, and HE4).

[0251] In this case, the third horizontal touch line HTL3 may overlap with the third electrode portion HE3, and may also overlap with the fourth electrode portion HE4 that overlaps with the third vertical touch line VTL3.

[0253] In this case, the third horizontal touch line HTL3 may overlap with the first electrode portion HE1, the second electrode portion HE2, the third electrode portion HE3, and the fourth electrode portion HE4 that overlap with the third vertical touch line VTL3. The third horizontal touch line HTL3 may be electrically connected to the third electrode portion HE3 among the first electrode portion HE1, the second electrode portion HE2, the third electrode portion HE3, and the fourth electrode portion HE4 that overlap with the third vertical touch line VTL3, and may be electrically separated from the first electrode portion HE1, the second electrode portion HE2, and the fourth electrode portion HE4.

[0254] In the touch sensor unit TSU having a braided touch sensor structure according to an embodiment of the present invention, the fourth vertical touch line VTL4 may overlap with the second electrode portion HE2 and the third electrode portion HE3 located in the same column, and may not overlap with the first bridging portion HB1, the second bridging portion HB2, and the third bridging portion HB3 located in the same column.

[0255] The area of the first protrusion portion PP of the first separated electrode V1A included in the first vertical electrode V1 may be substantially equal to or close to the area of the first bridging portion HB1 of the first horizontal electrode H1.

[0256] Therefore, the area of each of the first to fourth horizontal electrodes (H1 - H4) may be substantially equal to or close to the area of each of the first to fourth vertical electrodes (V1 - V4). As a result, it is possible to prevent the degradation of touch sensitivity due to the difference in electrode area.

[0257] In Figure 10 the braided touch sensor structure, similar to or approximately equivalent to Figure 8 the braided touch sensor structure, it is possible to reduce the parasitic capacitance between the touch electrodes (H1 - H4 and V1 - V4) and the display driving lines (GL and DL), thereby improving the touch sensitivity.

[0258] Furthermore, in Figure 10In the woven touch sensor structure, the difference in area between each of the first to fourth horizontal electrodes (H1-H4) and each of the first to fourth vertical electrodes (V1-V4) can be reduced, thereby further improving touch sensitivity.

[0259] Meanwhile, in Figure 10 the woven touch sensor structure, the first to fourth vertical touch lines (VTL1-VTL4) can be connected to the protrusions PP formed in the first to fourth partition electrodes (V1A-V1D, V2A-V2D, V3A-V3D, and V4A-V4D).
