Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims priority to Korean Patent Application No. 10-2018-0113729, filed on September 21, 2018. BACKGROUND OF THE INVENTION 1. Field of the Invention

[0002] The present disclosure relates to a touch-sensitive display device. 2. Description of related technology

[0003] A touch-sensitive display device, in addition to the function of displaying videos or images, can provide a touch-based input function that allows a user to enter information or instructions easily, intuitively and conveniently.

[0004] Such a touch-sensitive display device should be able to detect whether a user has touched the touch-sensitive display device and precisely detect the touch coordinates to provide the touch-based input function. For this purpose, touch-sensitive displays comprise a touch-sensitive panel having a touch sensor structure.

[0005] The touch-sensitive panel has a touch-sensitive sensor structure including: a plurality of touch electrodes, a plurality of touch guide lines for connecting the touch electrodes to a touch detection circuit, and so on. A plurality of touch pads (or a plurality of touch channels) to which the touch detection circuit is electrically connected may exist in the touch-sensitive panel.

[0006] Since such a touch-sensitive panel has a touch detection structure that is complicated or requires multiple layers, there may be a problem that the manufacturing process of the touch-sensitive panel is complicated, or the manufacturing yield of the touch-sensitive panel is low, or the manufacturing cost increases.

[0007] As the size of a touch panel increases, the number of touch electrodes increases, as do the number of signal lines and the number of touch channels. Accordingly, the problem of increasing panel manufacturing complexity and cost, as well as increasing circuit component manufacturing complexity and cost, can worsen.

[0008] Related art touch panels have a problem in that a phantom phenomenon occurs in which points that have not actually been touched are detected as touch positions when multiple touches occur.

[0009] Exemplary touch-sensitive display devices are known from US 2017 / 0 102 804 A1, US 2015 / 0 277 655 A1, US 2012 / 0 313 881 A1, US 2017 / 0 115 809 A1, US 2018 / 0 136 755 A1 and US 2010 / 0 302 180 A1. CONTENT OF THE INVENTION

Furthermore, the term "could" fully encompasses all meanings of the term "may."

[0064] Fig. 1 is a schematic system configuration diagram of a touch-sensitive display device according to embodiments of the present disclosure.

[0065] Referring to Fig. 1, a touch-sensitive display device according to embodiments of the present disclosure may provide both a function for displaying images and a function for detecting a touch.

[0066] To provide an image display function, a touch-sensitive display device according to embodiments of the present disclosure may include: a display panel DISP on which a plurality of data lines and a plurality of gate lines are arranged, and a plurality of subpixels defined by the plurality of data lines and the plurality of gate lines are arranged; a data driver circuit DDC that drives the plurality of data lines; a gate driver circuit GDC that drives the plurality of gate lines; a display control unit DCTR that controls an operation of the data driver circuit DDC and the gate driver circuit GDC, etc.

[0067] The data driver circuit DDC, the gate driver circuit GDC, and the display control unit DCTR may each be implemented by one or more separate parts. Depending on the case, two or more of the data driver circuit DDC, the gate driver circuit GDC, and the display control unit DCTR may be integrally implemented in a single part. For example, the data driver circuit DDC and the display control unit DCTR may be implemented in one integrated circuit chip (IC chip).

[0068] To provide the touch detection function, the touch-sensitive display device according to embodiments of the present disclosure may include: a touch-sensitive panel TSP having a plurality of touch electrodes; and a touch detection circuit TSC that supplies a touch drive signal to the touch-sensitive panel TSP, detects a touch detection signal from the touch-sensitive panel TSP, and detects whether there has been a touch by a user, or detects a touch position (touch coordinates) on the touch-sensitive panel TSP based on the detected touch detection signal.

[0069] The touch detection circuit TSC may include, for example, a touch driver circuit TDC that supplies a touch drive signal to the touch-sensitive panel TSP and detects a touch detection signal from the touch-sensitive panel TSP; and a touch control unit TCTR that detects whether there has been a touch by a user and / or detects a touch position on the touch-sensitive panel TSP based on the touch detection signal detected by the touch driver circuit TDC.

[0070] The touch driver circuit TDC may include a first circuit part that supplies a touch drive signal to the touch-sensitive panel TSP, and a second circuit part that detects a touch detection signal from the touch-sensitive panel TSP. The first circuit part and the second circuit part may be integrated into a single part or may be separate.

[0071] The touch driver circuit TDC and the touch control unit TCTR may be implemented as separate parts or may be implemented integrally in a single part.

[0072] The data driver circuit DDC, the gate driver circuit GDC, and the touch driver circuit TDC may each be implemented as one or more integrated circuits, or may be implemented in a chip-on-glass (COG) type, a chip-on-film (COF) type, or a tape carrier package (TCP) type with respect to electrical connection to the display panel DISP, and the gate driver circuit GDC may be implemented in a gate-in-panel (GIP) type.

[0073] The circuit components DDC, GDC, and DCTR for display control and the circuit components TDC and TCTR for touch control and detection can each be implemented as one part or as multiple separate parts. Depending on the case, one or more of the circuit components DDC, GDC, and DCTR for display control and one or more of the circuit components TDC and TCTR for touch control and detection can be functionally integrated or can be implemented as one part or as multiple separate parts. For example, the data driver circuit DDC and the touch driver circuit TDC can be integrally implemented in one, two, or more integrated circuit chips.When the data driver circuit DDC and the touch driver circuit TDC are integrally implemented in two or more integrated circuit chips, each of the two or more integrated circuit chips may have a data driver function and a touch driver function.

[0074] The touch-sensitive display device according to embodiments of the present disclosure may be of numerous types, such as a liquid crystal display (LCD) type and an organic light-emitting diode (OLED) type. The case where the touch-sensitive display device is an LCD will be used as an example below for the convenience of description. That is, the display panel DISP may be of various types, such as an OLED panel and an LCD panel, but for the convenience of description, the display panel DISP will be exemplified below as an LCD panel.

[0076] The touch-sensitive panel (TSP) can exist outside the display panel (DISP). This means that the touch-sensitive panel (TSP) and the display panel (DISP) can be manufactured separately and then connected. The touch-sensitive panel (TSP) is referred to as an external type or a supplementary type.

[0077] In contrast, the touch-sensitive panel TSP can be arranged in the display panel DISP. That is, when the display panel DISP is manufactured, the touch sensor structure, such as the plurality of touch electrodes constituting the touch-sensitive panel TSP and the plurality of signal lines with electrodes and signal lines for display control, can be formed. This touch-sensitive panel TSP is referred to as a built-in type. The case where the touch-sensitive panel TSP is of a built-in type is cited below as an example for the convenience of description.

[0078] The size of each of the touch electrodes described herein may correspond to the area size of one subpixel and may correspond to the area size of two or more subpixels.

[0079] The touch electrodes can be plate-like, without an opening, or mesh-like, with one or more openings.

[0080] When a touch electrode is mesh-like and has a size corresponding to the area size of two or more subpixels, the touch electrode may have two or more openings, and the position and size of each of the two or more openings may correspond to the position and size of a light emitting area of the subpixels.

[0083] Referring to Fig. 2, when the touch-sensitive panel is a split-type touch-sensitive panel, each of a plurality of touch electrodes TE may be electrically connected to signal lines SL through one or more contact holes CNT.

[0084] The plurality of touch electrodes TE may be arranged in an active area. Depending on the case, some (e.g., outermost touch electrodes) of the plurality of touch electrodes TE may be arranged in an outer region (outer region) of the active area or may extend to the outer region (outer region) of the active area. The active area may be an area in which images are displayed or touch detection is possible.

[0085] As in Fig. As shown in Figure 2, a plurality of signal lines SL electrically connected to the plurality of touch electrodes TE may be arranged in an active area. Depending on the case, all or some of the plurality of signal lines SL may be arranged outside the active area.

[0086] As in Fig. 2, when the plurality of signal lines SL electrically connected to the plurality of touch electrodes TE are arranged in the active region, the plurality of signal lines SL may be arranged in a layer different from the plurality of touch electrodes TE, thereby overlapping the plurality of touch electrodes TE.

[0087] As in Fig. As shown in Figure 2, all of the plurality of signal lines SL may have the same or a similar length and may be arranged from the point connected to the touch detection circuit TSC to the opposite point. The plurality of signal lines SL may differ only in the position (ie, the position of the contact hole CNT) at which they are respectively electrically connected to the touch electrodes TE.

[0088] Alternatively, the plurality of signal lines SL may extend from the points connected to the touch detection circuit TSC to the points at which corresponding contact holes CNT are arranged.

[0089] The following may refer to Fig. 2 the plurality of touch electrodes TE are referred to as touch units TU in the split type touch panel TSP.

[0090] Referring to Fig. 2. If the touch-sensitive panel TSP is of a split type and a touch electrode TE is electrically connected to a signal line SL, there should be as many signal lines SL as touch electrodes TE. The number of the plurality of signal lines SL corresponds to the number of touch channels for signal input / output of the touch driver circuit TDC.

[0091] According to the Fig. In the example shown in Figure 2, sixteen touch electrodes TE are arranged in four rows and four columns in the touch-sensitive panel TSP. In this case, sixteen signal lines SL and sixteen touch channels can exist. That is, the number of touch electrodes of a split-type touch-sensitive panel TSP is determined as the product of the number of touch electrodes arranged in a touch electrode row and the number of touch electrodes arranged in a touch electrode column.

[0092] That is, in the split-type touch panel TSP, the number of touch channels and the number of signal lines are determined as the product of the number of touch electrodes arranged in a touch electrode row and the number of touch electrodes arranged in a touch electrode column.

[0093] Accordingly, in a split-type touch panel TSP, the number of signal lines and the number of touch channels increase with the increase in the number of touch electrodes.

[0094] As the size of the touch-sensitive panel (TSP) increases, or as multiple touch electrodes are deployed to increase touch detection precision, the number of signal lines and touch channels may increase excessively. Accordingly, panel manufacturing may become complicated, and the touch driver circuit (TDC) may become complex and expensive.

[0095] The Fig. The split-type touch-sensitive panel TSP shown in Fig. 2 may be a touch sensor for detecting touches based on the self-capacitance of each of the touch electrodes TE or may be a touch sensor for detecting touches based on a mutual capacitance between the touch electrodes TE.

[0096] Fig. 3 is a diagram illustrating an increase in a size of a touch electrode in a split-type touch panel TSP by the number of signal wires and touch channels in a touch-sensitive display device according to embodiments of the present disclosure.

[0097] As in Fig. 3, in a touch display device, it is possible to increase the touch electrode size (touch unit size) in a split-type touch panel TSP to reduce the number of signal lines and the number of touch channels.

[0098] According to the example of Fig. 3, the number of touch electrodes (the number of touch units) is reduced from 16 (=4*4) to 9 (=3*3), and the number of signal lines and the number of touch channels are also reduced from 16 (=4*4) to 9 (=3*3).

[0099] As described above, when a touch electrode size is increased, it is possible to reduce the number of touch electrodes, the number of signal lines, and the number of touch channels, but the touch detection function may be impaired.

[0100] For example, if a touch electrode size is increased, two or more touch positions may be detected even if a user has actually touched a point. This phenomenon is called finger separation or touch separation.

[0101] Fig. 4 is a diagram showing a matrix-type touch-sensitive panel TSP of a touch-sensitive display device according to embodiments of the present disclosure.

[0102] Referring to Fig. 4, when the touch-sensitive panel TSP of a touch-sensitive display device according to embodiments of the present disclosure is of a matrix type, a plurality of touch electrodes TE_H1 ~ TE_H4 arranged in the row direction and a plurality of touch electrodes TE_V1 ~ TE_V4 arranged in the column direction may be arranged one above the other in the touch-sensitive panel TSP.

[0103] The plurality of touch electrodes TE_H1 - TE_H4 arranged in the row direction may each be configured as one electrode.

[0104] In contrast, the Fig. 4, each of the plurality of touch electrodes TE_H1-TE_H4 arranged in the row direction may be formed of a plurality of separate electrodes EH that are electrically connected to each other. In this case, the plurality of separate electrodes EH included in each of the plurality of touch electrodes TE_H1-TE_H4 arranged in the row direction may be electrically connected by bridges BP.

[0105] Since the multiple separate electrodes EH included in each of the plurality of touch electrodes TE_H1 - TE_H4 arranged in the row direction are electrically connected by the bridges BP, they have an electrically equivalent potential. The bridges BP and the multiple separate electrodes EH are arranged in different layers and may be electrically connected by contact holes.

[0106] The plurality of touch electrodes TE_V1 ~ TE_V4 arranged in the column direction may each be composed of a plurality of separate electrodes EH electrically connected to each other.

[0107] In contrast, the Fig. 4, arranged in the column direction, may each be configured as one electrode EV.

[0108] The shape, arrangement and configuration of the touch electrodes TE_H1 ∼ TE_H4 and TE_V1 - TE_V4, which are Fig. 4 are merely examples for implementing a matrix-type touch-sensitive display panel TSP and can be implemented in numerous ways, but are not limited thereto.

[0109] According to the example of Fig. 4, a signal line SL_H may be connected to each of the four touch electrodes TE_H1 ~ TE_H4 arranged in the row direction. A signal line SL_V may be connected to each of the four touch electrodes TE_V1 ~ TE_V4 arranged in the column direction.

[0110] In the Fig. 4, the number of signal lines is the sum of the number of touch electrodes TE_H1 ~ TE_H4 arranged in the row direction and the number of touch electrodes TE_V1 - TE_V4 arranged in the column direction.

[0111] The Fig. The matrix-type touch-sensitive panel TSP shown in Figure 4 has the same size as the one shown in Fig. 2 shown touch-sensitive panel TSP of the split type. Accordingly, the number of touch units in the touch-sensitive panel is Fig. 4 equal to that in Fig. 2 and is 16 (=4*4).

[0112] In the Fig. However, in the matrix-type touch-sensitive panel TSP shown in Fig. 4, the total number of signal lines is 8 (=4+4), which is smaller than 16 (=4*4), that is, the number of signal lines in the split-type touch-sensitive panel TSP of Fig. 2 is.

[0113] Similarly, in the Fig. 4, the total number of touch channels is 8 (=4+4), which is less than 16 (4*4), that is, the number of touch channels in the split type touch panel TSP of Fig. 2 is.

[0114] Accordingly, it is possible to reduce the number of signal lines and the number of touch-sensitive panels by arranging the plurality of touch electrodes TE_H1 - TE_H4 and TE_V1 - TE_V4 included in one touch-sensitive panel TSP as shown in Fig. 4, in a matrix type, ie by implementing the touch-sensitive panel TSP as a matrix type.

[0115] The Fig. The matrix-type touch-sensitive panel TSP shown in Fig. 4 may be a touch sensor for detecting touches based on the self-capacitance of each of the touch electrodes TE_H1 ~ TE_H4 and TE_V1 - TE_V4 that cross each other, or may be a touch sensor for detecting touches based on a mutual capacitance between the touch electrodes TE_H1 ~ TE_H4 arranged in the row direction and the touch electrodes TE_V1 ~ TE_V4 arranged in the column direction.

[0116] Fig. 5 is a diagram showing a phantom phenomenon occurring in a multi-touch in a matrix-type touch panel TSP of a touch display device according to embodiments of the present disclosure.

[0117] Referring to Fig. 5, when the touch-sensitive panel of a touch-sensitive display device according to embodiments of the present disclosure is a matrix-type touch-sensitive panel TSP, touch electrodes TE_H1 ~ TE_H4 arranged in the row direction and touch electrodes TE_V1 ~ TE_V4 arranged in the column direction are arranged to cross each other.

[0118] Accordingly, when a user simultaneously touches two or more points n1 and n2 (T1 and T2), a touch detection circuit can detect whether the user has touched not only the actually touched points n1 and n2, but also points ng that the user has not actually touched.

[0119] That is, in the matrix-type touch-sensitive panel TSP, when multiple touches T1 and T2 occur at two or more points n1 and n2, the touch detection circuit TSC may mistakenly consider the actual touch points n1 and n2 and false touch points ng all as touch points.

[0120] This phenomenon, in which the false contact points are mistakenly considered to be contact points, as described above, is called the “phantom phenomenon”.

[0121] The false contact points ng at which the phantom phenomenon occurs are points where the points n1 and n2 with the actual multiple contacts T1 and T2 cross each other in the row direction and the column direction.

[0122] The phantom phenomenon may occur because touch electrodes that cross each other (TE_H1, TE_H3, TE_V2 and TE_V4 in the example of Fig. 5) act as paths through which charge is transferred by multiple contacts T1 and T2, at the actual contact points n1 and n2. In Fig. 5, the arrows show a transfer of charge causing a phantom phenomenon.

[0123] As described above, in a split-type touch panel (TSP), since many touch electrodes are provided, a drawback exists in that the number of signal lines and the number of touch channels also increase. This problem can be solved by increasing the touch electrode size. However, a drawback still exists in that the touch detection performance is impaired due to finger separation, etc.

[0124] In contrast, the matrix-type touch-sensitive panel TSP has a defect in that, although it is possible to reduce the number of signal lines and the number of touch channels, a phantom phenomenon occurs in a multiple touch.

[0125] Accordingly, embodiments of the present disclosure additionally propose a touch-sensitive panel TSP having a special electrode arrangement structure and electrode connection structure to reduce the number of signal lines and the number of touch channels and prevent a phantom phenomenon from occurring even in a multi-touch.

[0126] This touch-sensitive panel (TSP) is hereinafter referred to as a "woven type." "Woven type" may mean that the electrodes are intricately interlaced, or it may mean that the electrodes are interlaced.

[0127] Such a woven-type touch-sensitive panel (TSP) has an electrode array structure and an electrode connection structure that separate charge transfer paths based on touches at multiple points. Accordingly, it is possible to prevent charge generated at actual touch points n1 and n2 from being transferred to other surrounding points (points that may cause a phantom phenomenon). This woven type is also referred to as a "multi-interruption-point matrix type."

[0128] Fig. 6 to 11 are illustrations of woven-type touch-sensitive panels TSP in a touch-sensitive display device according to embodiments of the present disclosure.

[0129] Fig. 6 to 8 are diagrams showing a woven-type touch panel TSP having 2*2 repeating touch units TU in a touch-sensitive display device according to embodiments of the present disclosure, wherein Fig. Fig. 6 is a diagram showing an electrode array structure, and Fig. 7 is a diagram showing an electrode connection structure in the electrode arrangement structure of Fig. 6 shows. Fig. Fig. 8 is a diagram showing the configuration of an actual touch sensor (touch electrodes) according to the electrode connection structure of Fig. 7 shows.

[0130] Fig. 9 and Fig. 10 are diagrams illustrating a main cross-sectional structure of a woven-type touch panel TSP of a touch-sensitive display device according to embodiments of the present disclosure, and Fig. 11 is a diagram illustrating a phantom phenomenon reducing effect of a woven type touch panel TSP of a touch display device according to embodiments of the present disclosure.

[0131] Referring to Fig. 6, a touch-sensitive panel TSP may have a plurality of electrodes TE(i-4)1 ~ TE(i-4)4, TE(i-3)1 ~ TE(i-3)2, TE(i-2)1 ~ TE(i-2)4, TE(i-1)1 ~ TE(i-1)3, TE(i)1 ~ TE(i)4, TE(i+1)1 ~ TE(i+1)2, TE(i+2)1 ~ TE(i+2)4, and TE(i+3)1 ~ TE(i+3)3. Here, i can be an integer greater than 4.

[0132] Referring to Fig. 7, the touch-sensitive panel TSP may include a plurality of signal lines SL electrically connected to the plurality of electrodes TE(i-4)1 - TE(i-4)4, TE(i-3)1 ~ TE(i-3)2, TE(i-2)1 - TE(i-2)4, TE(i-1)1 ~ TE(i-1)3, TE(i)1 ~ TE(i)4, TE(i+1)1 ~ TE(i+1)2, TE(i+2)1 ~ TE(i+2)4, and TE(i+3)1 ~ TE(i+3)3 through a plurality of contact holes CNT. The plurality of signal lines SL may be grouped into two or more signal line groups SLG1, SLG2, SLG3, and SLG4.

[0133] The plurality of electrodes TE(i-4)1 ~ TE(i-4)4, TE(i-3)1 ∼ TE(i-3)2, TE(i-2)1 ∼ TE(i-2)4, TE(i-1)1 ∼ TE(i-1)3, TE(i)1 ∼ TE(i)4, TE(i+1)1 ∼ TE(i+1)2, TE(i+2)1 ∼ TE(i+2)4 and TE(i+3)1 ∼ TE(i+3)3 may be arranged in a plurality of electrode rows i-4, i-3, i-2, i-1, i, i+1, i+2 and i+3.

[0134] In the woven type touch panel TSP according to embodiments of the present disclosure, the same number of electrodes is not arranged in each of the plurality of electrode rows i-4, i-3, i-2, i-1, i, i+1, i+2, and i+3.

[0135] In the woven-type touch-sensitive panel TSP according to embodiments of the present disclosure, more electrodes may be arranged in one electrode row (e.g., i) of two adjacent electrode rows (e.g., i+1 and i) than in the other electrode row (e.g., i+1) in the plurality of electrode rows i-4, i-3, i-2, i-1, i, i+1, i+2, and i+3.

[0136] Accordingly, the sizes of the electrodes (e.g., TE(i+1)1 and TE(i+1)2) in one electrode row (e.g., i+1) of two adjacent electrode rows (e.g., i+1 and i) of the plurality of electrode rows i-4, i-3, i-2, i-1, i, i+1, i+2, and i+3 may be equal to or larger than the sizes of the electrodes (e.g., TE(i)1, TE(i)2, TE(i)3, and TE(i)4) in the other electrode row (e.g., i).

[0137] Referring to the Fig. 6 to 8, the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+2)1 in the i+2-th electrode row may be electrically connected to each other by a first signal line SL_1B.

[0138] Referring to the Fig. 6 to 8, the k-th electrode TE(i)k in the i-th electrode row and the k-th electrode TE(i-2)k in the i-2-th electrode row may be electrically connected to each other by a second signal line SL_2A.

[0139] The above-mentioned k can show how many electrodes arranged in the same electrode row alternate in a connection pattern and can be a natural number equal to or greater than 2.

[0140] k is equal to 2 in the Fig. 6 to 11 illustrated touch-sensitive panel TSP.

[0141] Accordingly, in the following description, the k-th electrode TE(i)k in the i-th electrode row is referred to as a second electrode TE(i)2 and the k-th electrode TE(i-2)k in the i-2-th electrode row is referred to as a second electrode TE(i-2)2.

[0142] Referring to the Fig. 6 to 8, the numbers of electrodes arranged in the odd-numbered electrode rows and the numbers of electrodes arranged in the even-numbered electrode rows may be different from each other.

[0143] Accordingly, the sizes of the electrodes arranged in the odd-numbered electrode rows and the sizes of the electrodes arranged in the even-numbered electrode rows may be different from each other.

[0144] However, the sizes of the electrodes arranged in the odd-numbered electrode rows may be the same. Furthermore, the sizes of the electrodes arranged in the even-numbered electrode rows may be the same.

[0145] Referring to the Fig. 6 to 8, assuming that the i-4th electrode row, the i-2nd electrode row, the i-th electrode row, and the i+2th electrode row are odd-numbered electrode rows, and the i-3rd electrode row, the i-1st electrode row, the i+1st electrode row, and the i+3rd electrode row are even-numbered electrode rows, the numbers of electrodes arranged in the odd-numbered electrode rows may be larger than the numbers of electrodes arranged in the even-numbered electrode rows. Accordingly, the sizes of the electrodes arranged in the odd-numbered electrode rows may be smaller than the sizes of the electrodes arranged in the even-numbered electrode rows.

[0146] Referring to the Fig. 6 to 8, the sizes of the first electrode TE(i)1 in the i-th electrode row, the first electrode TE(i+2)1 in the i+2-th electrode row, the second electrode TE(i)2 in the i-th electrode row, and the second electrode TE(i-2)2 in the i-2-th electrode row may correspond to each other.

[0147] Referring to the Fig. 6 to 8, the size of the first electrode TE(i+1)1 in the i+1-th electrode row, which is arranged between the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+2)1 in the i+2-th electrode row, may be equal to or larger than the sum of the size of the first electrode TE(i)1 in the i-th electrode row and the size of the first electrode TE(i+2)1 in the i+2-th electrode row.

[0148] Similarly, by reference to the Fig. 6 to 8, the size of the second electrode TE(i-1)2 in the i-1-th electrode row, which is arranged between the second electrode TE(i)2 in the i-th electrode row and the second electrode TE(i-2)2 in the i-2-th electrode row, may be equal to or greater than the sum of the size of the second electrode TE(i)2 in the i-th electrode row and the size of the second electrode TE(i-2)2 in the i-2-th electrode row.

[0149] Referring to the Fig. 6 to 8, the size of the first electrode TE(i+1)1 in the i+1-th electrode row, which is arranged between the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+2)1 in the i+2-th electrode row, may be equal to or larger than the sum of the size of the first electrode TE(i)1 and the size of the second electrode TE(i)2 in the i-th electrode row.

[0150] Referring to the Fig. 6 to 8, the second electrode TE(i-1)2 in the i-1-th electrode row, which is arranged between the second electrode TE(i)2 in the i-th electrode row and the second electrode TE(i-2)2 in the i-2-th electrode row, may have the same size as the first electrode TE(i+1)1 in the i+1-th electrode row, which is arranged between the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+2)1 in the i+2-th electrode row.

[0151] Referring to the Fig. 6 to 8, the second electrode TE(i-1)2 in the i-1-th electrode row, which is arranged between the second electrode TE(i)2 in the i-th electrode row and the second electrode TE(i-2)2 in the i-2-th electrode row, can be offset by an integer multiple (e.g., twice) of the electrode length in the row direction further than the first electrode TE(i+1)1 in the i+1-th electrode row, which is arranged between the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+2)1 in the i+2-th electrode row.

[0152] Referring to the Fig. 6 and Fig. 7, two or more electrodes TE(i)1 and TE(i+2)1 connected by a first signal line SL_1B may be separated from each other by another electrode TE(i+1)1.

[0153] Furthermore, two or more electrodes TE(i)1 and TE(i+2)1 connected by a first signal line SL_1B may be arranged separately in two or more non-adjacent electrode rows (i-th electrode row and i+2-th electrode row).

[0154] Moreover, two or more electrodes TE(i)1 and TE(i+2)1 connected by a first signal line SL_1B may be separated from each other by another electrode TE(i+1)1, but may be operated as one touch electrode in the equivalent potential state in the touch drive.

[0155] Similarly, two or more electrodes TE(i)2 and TE(i-2)2 connected by a second signal line SL_2A may be separated from each other by another electrode TE(i-1)2.

[0156] Furthermore, two or more electrodes TE(i)2 and TE(i-2)2 connected by a second signal line SL_2A may be separately arranged in two or more non-adjacent electrode rows (i-th electrode row and i-2-th electrode row).

[0157] Moreover, two or more electrodes TE(i)2 and TE(i-2)2 connected by a second signal line SL_2A may be separated from each other by another electrode TE(i-1)2, but they can be operated as one touch electrode in the equivalent potential state in touch driving.

[0158] As described above, two or more electrodes connected by a signal line are separated from each other by another electrode and arranged in different electrode rows, but they are electrically connected to each other and can work as a touch electrode.

[0159] A plurality of electrode rows included in a touch-sensitive panel TSP may have odd-numbered electrode rows and even-numbered electrode rows.

[0160] Referring to the Fig. 6 to 8, the electrodes TE(i-4)1 - TE(i-4)4, TE(i-2)1 ∼ TE(i-2)4, TE(i)1 ∼ TE(i)4 and TE(i+2)1 ∼ TE(i+2)4 (which are also referred to as vertical electrodes in the following description) arranged in the i-4th, i-2th, i-th and i+2th electrode rows, respectively, which may be odd-numbered or even-numbered electrode rows out of odd-numbered electrode rows and even-numbered electrode rows, are grouped vertically in two or more, and one signal line may be connected to each group (each touch electrode).

[0161] According to the example of Fig. 8, the electrodes TE(i-4)1 ∼ TE(i-4)4, TE(i-2)1 TE(i-2)4, TE(i)1 ∼ TE(i)4 and TE(i+2)1 ∼ TE(i+2)4 arranged in the i-4th, i-2th, i-th, and i+2th electrode rows, respectively, are grouped in pairs, thereby forming a plurality of touch electrodes V1-1, V2-1, V3-1, V4-1, V1-2, V2-2, V3-2, V4-2, V2-3, V4-3.

[0162] Referring to Fig. 8, considering the touch electrode matrix of only the plurality of touch electrodes V1-1, V2-1, V3-1, V4-1, V1-2, V2-2, V3-2, V4-2, V2-3, V4-3, ... formed by grouping the vertical electrodes, the first touch electrode columns V1-1 and V1-2 and the third touch electrode columns V3-1 and V3-2 are arranged in the same manner, and the second touch electrode columns V2-1, V2-2 and V2-3 and the fourth touch electrode columns V4-1, V4-2 and V4-3 are arranged in the same manner.

[0163] However, the second touch electrode columns V2-1, V2-2 and V2-3 and the fourth electrode columns V4-1, V4-2 and V4-3 are offset by an integer multiple (e.g., twice) of the height of a vertical electrode (e.g., TE(i)1) compared to the first touch electrode columns V1-1 and V1-2 and the third touch electrode columns V3-1 and V3-2.

[0164] The plurality of touch electrodes V1-1, V2-1, V3-1, V4-1, V1-2, V2-2, V3-2, V4-2, V2-3, V4-3, ... are similar to the vertical touch electrodes TE_V1, TE_V2, TE_V3 and TE_V4 in the matrix-type touch-sensitive panel TSP of Fig. 4.

[0165] Referring to the Fig. 6 to 8, the electrodes TE(i-3)1 ~ TE(i-3)2, TE(i-1)1 ∼ TE(i-1)3, TE(i+1)1 ∼ TE(i+1)2 and TE(i+3)1 ∼ TE(i+3)3 (which are also referred to as horizontal electrodes in the following description) arranged in the i-3th, i-1th, i+1th and i+3th electrode rows, which may be even-numbered or odd-numbered electrode rows of odd-numbered and even-numbered electrode rows, may be individually connected by signal lines without being grouped.

[0166] According to the example of Fig. 8, the electrodes TE(i-3)1 ∼ TE(i-3)2, TE(i-1)1 ∼ TE(i-1)3, TE(i+1)1 ∼ TE(i+1)2 and TE(i+3)1 ∼ TE(i+3)3, which are arranged in the i-3th, i-1th, i+1th and i+3th electrode rows, respectively, form touch electrodes H1-1, H1-2, H2-1, H2-2, H2-3, H3-1, H3-2, H4-1, H4-2, H4-3.

[0167] Referring to Fig. 8, considering the touch electrode matrix of only the plurality of touch electrodes H1-1, H1-2, H2-1, H2-2, H2-3, H3-1, H3-2, H4-1, H4-2, H4-3, ... formed of the horizontal electrodes, the first touch electrode rows H1-1 and H1-2 and the third touch electrode rows H3-1 and H3-2 are arranged in the same manner, and the second touch electrode rows H2-1, H2-2 and H2-3 and the fourth touch electrode rows H4-1, H4-2 and H4-3 are arranged in the same manner.

[0168] However, the second touch electrode rows H2-1, H2-2 and H2-3 and the fourth touch electrode rows H4-1, H4-2 and H4-3 are offset by 1 / 2 the length of a horizontal electrode (e.g., TE(i+1)1) compared to the first touch electrode rows H1-1 and H1-2 and the third touch electrode rows H3-1 and H3-2.

[0169] The individual touch electrodes H1-1, H1-2, H2-1, H2-2, H2-3, H3-1, H3-2, H4-1, H4-2, H4-3, ... are similar to the horizontal touch electrodes TE_H1, TE_H2, TE_H3 and TE_H4 in the matrix-type touch-sensitive panel TSP of Fig. 4.

[0170] Referring to the Fig. 6 to 10, several signal lines SL are each arranged in the column direction and can each overlap one or more electrodes.

[0171] Referring to the Fig. 6 to 10, all of a plurality of electrodes TE(i-4)1 ∼ TE(i-4)4, TE(i-3)1 ∼ TE(i-3)2, TE(i-2)1 ∼ TE(i-2)4, TE(i-1)1 ∼ TE(i-1)3, TE(i)1 ∼ TE(i)4, TE(i+1)1 ∼ TE(i+1)2, TE(i+2)1 ∼ TE(i+2)4 and TE(i+3)1 ∼ TE(i+3)3 may be arranged in the same layer.

[0172] Referring to the Fig. 6 to 10, a plurality of signal lines SL may be arranged in a layer different from that of the plurality of electrodes TE(i-4)1 ∼ TE(i-4)4, TE(i-3)1 ∼ TE(i-3)2, TE(i-2)1 ∼ TE(i-2)4, TE(i-1)1 ∼ TE(i-1)3, TE(i)1 ∼ TE(i)4, TE(i+1)1 ∼ TE(i+1)2, TE(i+2)1 ∼ TE(i+2)4 and TE(i+3)1 ∼ TE(i+3)3, with an insulating layer INS interposed therebetween.

[0173] Fig. 9 is a cross-sectional view (AB) of a region in which the first electrode TE(i)1 and the second electrode TE(i)2 are formed in the i-th electrode row. Fig. 10 is a cross-sectional view (CD) of a region in which a first signal line SL_1 B that overlaps the first electrode TE(i)1 in the i-th electrode row, the first electrode TE(i+1)1 in the i+1-th electrode row, the first electrode TE(i+2)1 in the i+2-th electrode row, and the first electrode TE(i+3)1 in the i+3-th electrode row, and electrically connects the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+2)1 in the i+2-th electrode row is formed.

[0174] Referring to Fig. 9, the first electrode TE(i)1 and the second electrode TE(i)2 in the i-th electrode row are arranged in an electrode metal layer. Similarly, by reference to Fig. 10, the first electrode TE(i)1 in the i-th electrode row, the first electrode TE(i+1)1 in the i+1-th electrode row, the first electrode TE(i+2)1 in the i+2-th electrode row, and the first electrode TE(i+3)1 in the i+3-th electrode row are arranged in an electrode metal layer. The electrode metal can, for example, be a material selected from a source / drain material, a gate material, and an ITO material.

[0175] Referring to the Fig. 9 and Fig. 10, an insulating layer INS may be arranged on the electrode metal layer.

[0176] Referring to the Fig. 9 and Fig. 10, a signal line metal layer in which signal lines SL are arranged may be arranged on the insulating layer INS. The signal line metal, for example, may be one of a source / drain material, a gate material, and an ITO material.

[0177] Referring to Fig. 9, a first signal line group SLG1 comprising a plurality of signal lines (including SL_1B) may be arranged on the insulating layer INS so as to overlap the first electrode TE(i)1 in the i-th electrode row. The first electrode TE(i)1 in the i-th electrode row should be electrically connected to a first signal line SL_1B among the plurality of signal lines in the first signal line group SLG1, so that the first electrode TE(i)1 in the i-th electrode row and the first signal line SL_1B can be connected through a contact hole CNT of the insulating layer INS.

[0178] Referring to Fig. 9, a second signal line group SLG2 comprising a plurality of signal lines (including SL_2A) may be arranged on the insulating layer INS so as to overlap the second electrode TE(i)2 in the i-th electrode row. The second electrode TE(i)2 in the i-th electrode row should be electrically connected to a second signal line SL_2A of the plurality of signal lines in the second signal line group SLG2, so that the second electrode TE(i)2 in the i-th electrode row and the second signal line SL_2A can be connected through a contact hole CNT of the insulating layer INS.

[0179] Referring to Fig. 10, the first signal line SL_1B is electrically separated from the first electrode, but may overlap the first electrode TE(i+1)1 in the i+1-th electrode row, which is arranged between the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+2)1 in the i+2-th electrode row.

[0180] This means that with reference to Fig. 10 the first signal line SL_1B can overlap the electrodes TE(i)1 and TE(i+2)1 which are to be electrically connected and can also overlap the electrodes TE(i+1)1, TE(i+3)1, ... in electrode rows which are different from the electrodes TE(i)1 and TE(i+2)1.

[0181] Similarly, the second signal line SL_2A is electrically separated from the second electrode, but may overlap the second electrode TE(i-1)2 in the i-1st electrode row, which is arranged between the second electrode TE(i)2 in the i-th electrode row and the second electrode TE(i-2)2 in the i-2nd electrode row.

[0182] In the woven type touch panel TSP, the number of electrodes electrically connected by each signal line SL is two or more.

[0183] Following the example of Fig. 6 to 8, the number of electrodes electrically connected by each signal line SL is two or more. That is, the number of electrodes electrically connected by the first signal line SL_1B is two, and the number of electrodes electrically connected by the second signal line SL_2A is two.

[0184] One or more electrodes (e.g., TE(i)1) of the electrodes (e.g., TE(i)1 and TE(i+2)1) electrically connected by the first signal line SL_1B and one or more electrodes (e.g., TE(i)2) of the electrodes (e.g., TE(i)2 and TE(i-2)2) electrically connected by the second signal line SL_2A may be arranged in the same electrode row (e.g., the i-th electrode row).

[0185] Referring to the Fig. 8 to 11, in the structure described above, assuming that the area obtained by connecting the portion corresponding to the length of a vertical electrode, a horizontal electrode (e.g., TE(i-3)1), and a vertical electrode (e.g., TE(i-4)1) is a touch unit TU, the area corresponding to a touch unit of two rows by two columns (2*2 TU, i.e., four TUs) is defined as a pattern unit PU. A touch panel TSP is formed by repeatedly forming the pattern unit PU.

[0186] Fig. 11 is a diagram in which touch electrodes V1-1, V2-1, V3-1, V4-1, V1-2, V2-2, V3-2, V4-2, V2-3, V4-3, ... formed by grouping vertical electrodes are indicated by vertical lines, and touch electrodes H1-1, H1-2, H2-1, H2-2, H2-3, H3-1, H3-2, H4-1, H4-2, H4-3, ... corresponding to horizontal electrodes are indicated by horizontal lines in Fig. 8 are indicated.

[0187] Referring to Fig. 11, when multiple touches T1 and T2 occur at two or more points n1 and n2, the possibility that the touch detection circuit TSC mistakes points other than the actual touch points n1 and n2 for touch points can be eliminated or reduced. That is, according to a woven-type touch-sensitive panel TSP, a phantom phenomenon can be prevented or reduced.

[0188] In a woven-type touch-sensitive panel (TSP), charge transfer causing a phantom phenomenon is prevented because the paths through which charge is transferred by multiple touches T1 and T2 at actual touch points n1 and n2 are interrupted. Accordingly, a phantom phenomenon can be prevented.

[0189] When a first touch T1 occurs at point n1 and a second touch T2 occurs simultaneously at point n2 (a point different from point n1), charge from the first touch is not transferred to the surroundings because two horizontal touch electrodes H1-1 and H1-2 are interrupted, and two vertical touch electrodes V2-1 and V2-2 are interrupted. Furthermore, charge from the second touch T2 is not transferred to the surroundings because two vertical touch electrodes V3-2 and V3-1 are interrupted, and two horizontal touch electrodes H3-2 and H3-1 are interrupted. Accordingly, a phantom phenomenon can be prevented.

[0190] Fig. 12 to 15 are diagrams showing a woven type touch panel TSP having 4*4 repeating touch units TU in a touch display device according to embodiments of the present disclosure, wherein Fig. 12 is a diagram showing an electrode array structure, Fig. 13 an electrode connection structure in the electrode arrangement structure of Fig. 12 is and Fig. 14 is a diagram showing the actual configuration of a touch sensor (touch electrodes) according to the electrode connection structure of Fig. 13 shows. Fig. 15 is a diagram showing a phantom phenomenon reducing effect of a woven type touch panel TSP of a touch display device according to embodiments of the present disclosure.

[0191] The touch-sensitive panel TSP of the Fig. 12 to 15 is the same as in the basic structure as the touch sensitive panel TSP of the Fig. 6 to 11. However, there is a difference in that the size of the pattern units PU of the touch-sensitive panel TSP of the Fig. 6 to 11 2*2 TU but the size of the sample units PU of the touch-sensitive panel TSP of the Fig. 12 to 15 4*4 TU. In addition, another difference is that k in the touch-sensitive panel TSP of the Fig. 6 to 11 is equal to 2 but k in the touch-sensitive panel TSP of the Fig. 12 to 15 equals 3.

[0192] Since the size of the sample units PU of the touch-sensitive panel TSP of the Fig. 12 to 15 4*4 TU, the number of electrodes arranged in one electrode row of two adjacent electrode rows is 1 / 4 of the number of electrodes arranged in the other electrode row. Accordingly, the length of the electrodes in one electrode row of two adjacent electrode rows is approximately four times the length of the electrodes in the other electrode row.

[0193] Referring to the Fig. 12 to 15, the length of each of the electrodes (horizontal electrodes) arranged in the i-7th, i-5th, i-3th, i-1th, i+1th, i+3th, i+5th and i+7th electrode rows is four times longer than the length of each of the electrodes (vertical electrodes) arranged in the i-8th, i-6th, i-4th, i-2th, i-th, i+2th, i+4th and i+6th electrode rows.

[0194] Following the example of Fig. 12 to 15, the touch-sensitive panel TSP may have sixteen electrode rows i-8, i-7, ..., i-1, i, i+1, ... and i+7.

[0195] Vertical electrodes are as follows. Eight electrodes TE(i-8)1 ∼ TE(i-8)8 are arranged in the i-8th electrode row. Eight electrodes TE(i-6)1 ∼ TE(i-6)8 are arranged in the i-6th electrode row. Eight electrodes TE(i-4)1 ∼ TE(i-4)8 are arranged in the i-4th electrode row. Eight electrodes TE(i-2)1 ∼ TE(i-2)8 are arranged in the i-2th electrode row. Eight electrodes TE(i)1 - TE(i)8 are arranged in the i-th electrode row. Eight electrodes TE(i+2)1 - TE(i+2)8 are arranged in the i+2th electrode row. Eight electrodes TE(i+4)1 - TE(i+4)8 are arranged in the i+4th electrode row. Eight electrodes TE(i+6)1 - TE(i+6)8 are arranged in the i+6th electrode row.

[0196] Horizontal electrodes are as follows. Two electrodes TE(i-7)1 ∼ TE(i-7)2 are arranged in the i-7th electrode row. Two electrodes TE(i-5)1 ∼ TE(i-5)2 are arranged in the i-5th electrode row. Three electrodes TE(i-3)1 ∼ TE(i-3)3 are arranged in the i-3th electrode row. Three electrodes TE(i-1)1 ~ TE(i-1)3 are arranged in the i-1th electrode row. Two electrodes TE(i+1)1 - TE(i+1)2 are arranged in the i+1th electrode row. Two electrodes TE(i+3)1 - TE(i+3)2 are arranged in the i+3th electrode row. Three electrodes TE(i+5)1 - TE(i+5)3 are arranged in the i+5th electrode row. Three electrodes TE(i+7)1 - TE(i+7)3 are arranged in the i+7th electrode row.

[0197] Referring to Fig. 13, the touch-sensitive panel TSP may include a plurality of signal lines SL electrically connected to the electrodes arranged in sixteen electrode rows i-8, i-7, ..., i-1, i, i+1, ..., and i+7 through a plurality of contact holes CNT. The plurality of signal lines SL may be grouped into eight signal line groups SLG1 - SLG8.

[0198] In the woven type touch panel TSP according to embodiments of the present disclosure, the same number of electrodes is not arranged in each of the sixteen electrode rows i-8, i-7, ..., i-1, i, i+1, ... and i+7.

[0199] In the woven type touch-sensitive panel TSP according to embodiments of the present disclosure, more electrodes may be arranged in each electrode row (e.g., i) of two adjacent electrode rows (e.g., i+1 and i) than in the other electrode row (e.g., i+1) in the sixteen electrode rows i-8, i-7, ..., i-1, i, i+1, ... and i+7.

[0200] Accordingly, the size of the electrodes (e.g. TE(i+1)1 and TE(i+1)2) in one electrode row (e.g. i+1) of two adjacent electrode rows (e.g. i+1 and i) of the sixteen electrode rows i-8, i-7, ... , i-1, i, i+1, ... and i+7 may be equal to or larger than the size of the electrodes (e.g. TE(i)1 - TE(i)8) in the other electrode row (e.g. i).

[0201] Referring to the Fig. 12 to 15, the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+2)1 in the i+2-th electrode row may be electrically connected to each other by a first signal line SL_1B.

[0202] Referring to the Fig. 12 to 15, the k-th electrode TE(i)k in the i-th electrode row and the k-th electrode TE(i-2)k in the i-2-th electrode row may be electrically connected to each other by a second signal line SL_3A.

[0203] The aforementioned term “k” may be a natural number greater than or equal to 2 and may indicate how many electrodes arranged in the same electrode row change together in the pattern.

[0204] k is 3 in the touch-sensitive panel TSP, which is used in the Fig. 12 to 15.

[0205] Accordingly, in the following description, the k-th electrode TE(i)k in the i-th electrode row is referred to as a third electrode TE(i)3 and the k-th electrode TE(i-2)k in the i-2-th electrode row is referred to as a third electrode TE(i-2)3.

[0206] Referring to the Fig. 12 to 15, the numbers of electrodes arranged in the odd-numbered electrode rows and the numbers of electrodes arranged in the even-numbered electrode rows may be different from each other.

[0207] The size of the electrodes arranged in the odd-numbered electrode rows and the size of the electrodes arranged in the even-numbered electrode rows may be different from each other.

[0208] However, the sizes of the electrodes arranged in the odd-numbered electrode rows may be the same. Furthermore, the sizes of the electrodes arranged in the even-numbered electrode rows may be the same.

[0209] Referring to the Fig. 12 to 15, assuming that the i-8th, i-6th, i-4th, i-2th, i-th, i+2th, i+4th, and i+6th electrode rows are odd-numbered electrode rows, and the i-7th, i-5th, i-3th, i-1st, i+1st, i+3rd, i+5th, and i+7th electrode rows are even-numbered electrode rows, the numbers of electrodes arranged in the odd-numbered electrode rows may be larger than the numbers of electrodes arranged in the even-numbered electrode rows. Accordingly, the sizes of the electrodes arranged in the odd-numbered electrode rows may be smaller than the sizes of the electrodes arranged in the even-numbered electrode rows.

[0210] Referring to the Fig. 12 to 15, the sizes of the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+2)1 in the i+2-th electrode row, the third electrode TE(i)3 in the i-th electrode row and the third electrode TE(i-2)3 in the i-2-th electrode row may correspond to each other.

[0211] Referring to the Fig. 12 to 15, the size of the first electrode TE(i+1)1 in the i+1-th electrode row, which is arranged between the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+2)1 in the i+2-th electrode row, may be equal to or larger than the sum of the size of the first electrode TE(i)1 in the i-th electrode row and the size of the first electrode TE(i+2)1 in the i+2-th electrode row.

[0212] Similarly, with reference to the Fig. 12 to 15, the size of the second electrode TE(i-1)2 in the i-1-th electrode row, which is arranged between the third electrode TE(i)3 in the i-th electrode row and the third electrode TE(i-2)3 in the i-2-th electrode row, may be equal to or greater than the sum of the size of the third electrode TE(i)3 in the i-th electrode row and the size of the third electrode TE(i-2)3 in the i-2-th electrode row.

[0213] Referring to the Fig. 12 to 15, the size of the first electrode TE(i+1)1 in the i+1-th electrode row, which is arranged between the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+2)1 in the i+2-th electrode row, may be equal to or larger than the sum of the size of the first electrode TE(i)1 and the size of the third electrode TE(i)3 in the i-th electrode row.

[0214] Referring to the Fig. 12 to 15, the second electrode TE(i-1)2 in the i-1-th electrode row, which is arranged between the third electrode TE(i)3 in the i-th electrode row and the third electrode TE(i-2)3 in the i-2-th electrode row, may have the same size as the first electrode TE(i+1)1 in the i+1-th electrode row, which is arranged between the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+2)1 in the i+2-th electrode row.

[0215] Referring to the Fig. 12 to 15, the second electrode TE(i-1)2 in the i-1-th electrode row, which is arranged between the third electrode TE(i)3 in the i-th electrode row and the third electrode TE(i-2)3 in the i-2-th electrode row, may be offset by an integer multiple (e.g., four times) of the electrode length in the row direction further than the first electrode TE(i+1)1 in the i+1-th electrode row, which is arranged between the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+2)1 in the i+2-th electrode row.

[0216] Referring to the Fig. 12 and Fig. 13, two or more electrodes TE(i)1 and TE(i+2)1 connected by a first signal line SL_1B may be separated from each other by another electrode TE(i+1)1. Furthermore, two or more electrodes TE(i)1 and TE(i+2)1 connected by a first signal line SL_1B may be separately arranged in two or more non-adjacent electrode rows (the i-th electrode row and the i+2-th electrode row). Furthermore, two or more electrodes TE(i)1 and TE(i+2)1 connected by a first signal line SL_1B are separated from each other by another electrode TE(i+1)1, but they can be operated as one touch electrode in the equivalent potential state in touch driving.

[0217] Similarly, two or more electrodes TE(i)3 and TE(i-2)3 connected by a second signal line SL_3A may be separated from each other by another electrode TE(i-1)2. Moreover, two or more electrodes TE(i)3 and TE(i-2)3 connected by a second signal line SL_3A may be separately arranged in two or more non-adjacent electrode rows (i-th electrode row and i-2-th electrode row). Moreover, two or more electrodes TE(i)3 and TE(i-2)3 connected by a second signal line SL_3A are separated from each other by another electrode TE(i-1)2, but they can be operated as one touch electrode in the equivalent potential state in a touch drive.

[0218] As described above, two or more electrodes connected by a signal line are separated from each other by another electrode and arranged in different electrode rows, but they are electrically connected to each other so that they can function as one touch electrode.

[0219] A plurality of electrode rows included in a touch-sensitive panel TSP may have odd-numbered electrode rows and even-numbered electrode rows.

[0220] Referring to the Fig. 12 to 15, the electrodes (vertical electrode) arranged in the i-8th, i-6th, i-4th, i-2th, i-th, i+2th, i+4th, and i+6th electrode rows, which may be odd-numbered or even-numbered electrode rows from odd-numbered electrode rows and even-numbered electrode rows, are grouped four by four vertically, and one signal line may be connected to each group (each touch electrode).

[0221] According to the example of Fig. 14, the electrodes arranged in the i-8th, i-6th, i-4th, i-2th, i-th, i+2th, i+4th and i+6th electrode rows are grouped four by four, thereby forming a plurality of touch electrodes V1-1, V2-1, ... , V8-1, V1-2, V2-2, ... , V8-2, V1-1, V2-1, ... , V8-1, V3-3, V4-3, V7-3, V8-3, ...

[0222] The plurality of touch electrodes V1-1, V2-1, ..., V8-1, V1-2, V2-2, ..., V8-2, V1-1, V2-1, ..., V8-1, V3-3, V4-3, V7-3, V8-3, ... are similar to the vertical touch electrodes TE_V1, TE_V2, TE_V3 and TE_V4 in the matrix-type touch-sensitive panel TSP of Fig. 4.

[0223] Referring to the Fig. 12 to 15, the electrodes (horizontal electrode) arranged in the i-7th, i-5th, i-3th, i-1th, i+1th, i+3th, i+5th, and i+7th electrode rows, which may be even-numbered or odd-numbered electrode rows of odd-numbered electrode rows and even-numbered electrode rows, may be individually connected to signal lines without being grouped.

[0224] According to the example of Fig. 14, the electrodes arranged in the i-7th, i-5th, i-3th, i-1th, i+1th, i+3th, i+5th and i+7th electrode rows individually form touch electrodes H1-1, H1-2, H2-1, H2-2, H3-1, H3-2, H3-3, H4-1, H4-2, H4-3, H5-1, H5-2, H6-1, H6-2, H7-1, H7-2, H7-3, H8-1, H8-2, H8-3, ....

[0225] The individual touch electrodes H1-1, H1-2, H2-1, H2-2, H3-1, H3-2, H3-3, H4-1, H4-2, H4-3, H5-1, H5-2, H6-1, H6-2, H7-1, H7-2, H7-3, H8-1, H8-2, H8-3, ... are corresponding to the horizontal touch electrodes TE_H1, TE_H2, TE_H3, TE_H4 in the matrix-type touch-sensitive panel TSP of Fig. 4 similar.

[0226] Referring to the Fig. 12 to 15, a plurality of signal lines SL are each arranged in the column direction and each can overlap one or more electrodes.

[0227] Referring to the Fig. 12 to 15, all of a plurality of electrodes may be arranged in the same layer.

[0228] Referring to the Fig. 12 to 15, a plurality of signal lines SL may be arranged in a layer different from a plurality of electrodes with an insulating layer INS therebetween.

[0229] Referring to the Fig. 12 to 15, in the structure described above, assuming that the area obtained by connecting a 1 / 4 point of a horizontal electrode (e.g., TE(i-7)1) and a vertical electrode (e.g., TE(i-8)1) is one touch unit TU, the area corresponding to a touch unit of four rows by four columns (4*4 TU, i.e., sixteen TUs) is defined as one pattern unit PU. A touch-sensitive panel TSP is formed by repeatedly forming the pattern unit PU.

[0230] Fig. 15 is a diagram in which touch electrodes V1-1, V2-1, ..., V8-1, V1-2, V2-2, ..., V8-2, V1-1, V2-1, ..., V8-1, V3-3, V4-3, V7-3, V8-3, ... obtained by grouping vertical electrodes are indicated by vertical lines, and touch electrodes corresponding to horizontal electrodes H1-1, H1-2, H2-1, H2-2, H3-1, H3-2, H3-3, H4-1, H4-2, H4-3, H5-1, H5-2, H6-1, H6-2, H7-1, H7-2, H7-3, H8-1, H8-2, H8-3, ... are indicated by horizontal lines in Fig. 14 indicated.

[0231] Referring to Fig. 15, when multiple touches T1 and T2 occur at two or more points n1 and n2, the possibility that the touch detection circuit TSC mistakes points other than the actual touch points n1 and n2 for touch points can be eliminated or reduced. That is, according to a woven-type touch-sensitive panel TSP, a phantom phenomenon can be prevented or reduced.

[0232] In a woven-type touch-sensitive panel (TSP), charge transfer causing a phantom phenomenon is prevented because the paths through which charge is transferred by multiple touches T1 and T2 at actual touch points n1 and n2 are interrupted. Accordingly, a phantom phenomenon can be prevented.

[0233] When a first touch T1 occurs at point n1 and a second touch T2 occurs simultaneously at point n2 (a point different from point n1), charge is not transferred to the surroundings by the second touch T2 because two horizontal touch electrodes H6-1 and H6-2 have been interrupted and two vertical touch electrodes V6-2 and V6-1 have been interrupted. Accordingly, a phantom phenomenon can be prevented.

[0234] Fig. 16 to 18 are diagrams showing a woven type touch panel TSP having 4*4 repeating touch units TU in a touch display device according to embodiments of the present disclosure, wherein Fig. 16 is a diagram showing an electrode array structure, Fig. 17 an electrode connection structure in the electrode arrangement structure of Fig. 16 and Fig. 18 is a diagram showing the actual configuration of a touch sensor (touch electrodes) according to the electrode connection structure of Fig. 17 shows. Fig. 19 is a diagram illustrating a phantom phenomenon reducing effect of a woven type touch panel TSP of a touch display device according to embodiments of the present disclosure.

[0235] The touch-sensitive panel TSP of the Fig. 16 to 19 is the same as in the basic structure as the touch sensitive panel TSP of the Fig. 12 to 15. In addition, another difference is that k in the touch-sensitive panel TSP of the Fig. 12 to 15 is equal to 3 but k in the touch-sensitive panel TSP of the Fig. 16 to 19 equals 2.

[0236] Since the size of the sample units PU of the touch-sensitive panel TSP of the Fig. 16 to 19 4*4 TU, the number of electrodes arranged in one electrode row of two adjacent electrode rows is 1 / 4 of the number of electrodes arranged in the other electrode row. Accordingly, the length of the electrodes in one electrode row of two adjacent electrode rows is approximately four times the length of the electrodes in the other electrode row.

[0237] Referring to the Fig. 16 to 19, the length of each of the electrodes (horizontal electrodes) arranged in the i-7th, i-5th, i-3th, i-1th, i+1th, i+3th, i+5th and i+7th electrode rows is four times longer than the length of each of the electrodes (vertical electrodes) arranged in the i-8th, i-6th, i-4th, i-2th, i-th, i+2th, i+4th and i+6th electrode rows.

[0238] Following the example of Fig. 16 to 19, the touch-sensitive panel TSP may have sixteen electrode rows i-8, i-7, ..., i-1, i, i+1, ..., i+7.

[0239] Vertical electrodes are as follows. Eight electrodes TE(i-8)1 ~ TE(i-8)8 are arranged in the i-8th electrode row. Eight electrodes TE(i-6)1 ∼ TE(i-6)8 are arranged in the i-6th electrode row. Eight electrodes TE(i-4)1 ∼ TE(i-4)8 are arranged in the i-4th electrode row. Eight electrodes TE(i-2)1 ∼ TE(i-2)8 are arranged in the i-2th electrode row. Eight electrodes TE(i)1 ∼ TE(i)8 are arranged in the i-th electrode row. Eight electrodes TE(i+2)1 ∼ TE(i+2)8 are arranged in the i+2th electrode row. Eight electrodes TE(i+4)1 ∼ TE(i+4)8 are arranged in the i+4th electrode row. Eight electrodes TE(i+6)1 ∼ TE(i+6)8 are arranged in the i+6th electrode row.

[0240] Horizontal electrodes are as follows. Two electrodes TE(i-7)1 ∼ TE(i-7)2 are arranged in the i-7th electrode row. Two electrodes TE(i-5)1 ∼ TE(i-5)2 are arranged in the i-5th electrode row. Three electrodes TE(i-3)1 ∼ TE(i-3)3 are arranged in the i-3th electrode row. Three electrodes TE(i-1)1 ∼ TE(i-1)3 are arranged in the i-1th electrode row. Two electrodes TE(i+1)1 ∼ TE(i+1)2 are arranged in the i+1th electrode row. Two electrodes TE(i+3)1 ~ TE(i+3)2 are arranged in the i+3th electrode row. Three electrodes TE(i+5)1 ~ TE(i+5)3 are arranged in the i+5th electrode row. Three electrodes TE(i+7)1 ~ TE(i+7)3 are arranged in the i+7th electrode row.

[0241] Referring to Fig. 17, the touch-sensitive panel TSP may include a plurality of signal lines SL electrically connected to the electrodes arranged in the sixteen electrode rows i-8, i-7, ..., i-1, i, i+1, ..., i+7 through a plurality of contact holes CNT. The plurality of signal lines SL may be grouped into eight signal line groups SLG1 ∼ SLG8.

[0242] In the woven type touch panel TSP according to embodiments of the present disclosure, the same number of electrodes is not arranged in each of the sixteen electrode rows i-8, i-7, ..., i-1, i, i+1, ..., i+7.

[0243] In the woven-type touch-sensitive panel TSP according to embodiments of the present disclosure, more electrodes may be arranged in one electrode row (e.g., i) of two adjacent electrode rows (e.g., i+1 and i) than in the other electrode row (e.g., i+1) in the sixteen electrode rows i-8, i-7, ..., i-1, i, i+1, ..., i+7.

[0244] Accordingly, the size of the electrodes (e.g., TE(i+1)1 and TE(i+1)2) in one electrode row (e.g., i+1) of two adjacent electrode rows (e.g., i+1 and i) of the sixteen electrode rows (i-8, i-7, ... , i-1, i, i+1, ... , i+7) can be equal to or larger than the size of the electrodes (e.g., TE(i)1 ∼ TE(i)8) in the other electrode row (e.g., i).

[0245] Referring to the Fig. 16 to 19, the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+2)1 in the i+2-th electrode row may be electrically connected to each other by a first signal line SL_1B.

[0247] The aforementioned term “k” may be a natural number greater than or equal to 2 and may indicate how many electrodes arranged in the same electrode row change together in the pattern.

[0248] k is 2 in the touch-sensitive panel TSP, which is used in the Fig. 16 to 19.

[0249] Accordingly, in the following description, the k-th electrode TE(i)k in the i-th electrode row is referred to as a second electrode TE(i)2 and the k-th electrode TE(i-2)k in the i-2-th electrode row is referred to as a second electrode TE(i-2)2.

[0251] The size of the electrodes arranged in the odd-numbered electrode rows and the size of the electrodes arranged in the even-numbered electrode rows may be different from each other.

[0252] However, the sizes of the electrodes arranged in the odd-numbered electrode rows may be the same. Furthermore, the sizes of the electrodes arranged in the even-numbered electrode rows may be the same.

[0253] Referring to the Fig. 16 to 19, assuming that the i-8th, i-6th, i-4th, i-2th, i-th, i+2th, i+4th, and i+6th electrode rows are odd-numbered electrode rows, and the i-7th, i-5th, i-3th, i-1st, i+1st, i+3th, i+5th, and i+7th electrode rows are even-numbered electrode rows, the numbers of electrodes arranged in the odd-numbered electrode rows may be larger than the numbers of electrodes arranged in the even-numbered electrode rows. Accordingly, the sizes of the electrodes arranged in the odd-numbered electrode rows may be smaller than the sizes of the electrodes arranged in the even-numbered electrode rows.

[0254] Referring to the Fig. 16 to 19, the sizes of the first electrode TE(i)1 in the i-th electrode row as well as the first electrode TE(i+2)1 in the i+2-th electrode row, the second electrode TE(i)2 in the i-th electrode row and the second electrode TE(i-2)2 in the i-2-th electrode row may correspond to each other.

[0255] Referring to the Fig. 16 to 19, the size of the first electrode TE(i+1)1 in the i+1-th electrode row, which is arranged between the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+2)1 in the i+2-th electrode row, may be equal to or larger than the sum of the size of the first electrode TE(i)1 in the i-th electrode row and the size of the first electrode TE(i+2)1 in the i+2-th electrode row.

[0256] Similarly, with reference to the Fig. 16 to 19, the size of the second electrode TE(i-1)2 in the i-1-th electrode row, which is arranged between the second electrode TE(i)2 in the i-th electrode row and the second electrode TE(i-2)2 in the i-2-th electrode row, may be equal to or greater than the sum of the size of the second electrode TE(i)2 in the i-th electrode row and the size of the second electrode TE(i-2)2 in the i-2-th electrode row.

[0257] Referring to the Fig. 16 to 19, the size of the first electrode TE(i+1)1 in the i+1-th electrode row, which is arranged between the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+2)1 in the i+2-th electrode row, may be equal to or larger than the sum of the size of the first electrode TE(i)1 and the size of the second electrode TE(i)2 in the i-th electrode row.

[0258] Referring to the Fig. 16 to 19, the second electrode TE(i-1)2 in the i-1-th electrode row, which is arranged between the second electrode TE(i)2 in the i-th electrode row and the second electrode TE(i-2)2 in the i-2-th electrode row, may have the same size as the first electrode TE(i+1)1 in the i+1-th electrode row, which is arranged between the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+2)1 in the i+2-th electrode row.

[0259] Referring to the Fig. 16 to 19, the second electrode TE(i-1)2 in the i-1-th electrode row, which is arranged between the second electrode TE(i)2 in the i-th electrode row and the second electrode TE(i-2)2 in the i-2-th electrode row, may be offset by an integer multiple (e.g., four times) of the electrode length in the row direction further than the first electrode TE(i+1)1 in the i+1-th electrode row, which is arranged between the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+2)1 in the i+2-th electrode row.

[0260] Referring to the Fig. 16 and Fig. 17, two or more electrodes TE(i)1 and TE(i+2)1 connected by a first signal line SL_1B may be separated from each other by another electrode TE(i+1)1. Moreover, two or more electrodes TE(i)1 and TE(i+2)1 connected by a first signal line SL_1B may be separately arranged in two or more non-adjacent electrode rows (i-th electrode row and i+2-th electrode row). Moreover, two or more electrodes TE(i)1 and TE(i+2)1 connected by a first signal line SL_1B are separated from each other by another electrode TE(i+1)1 but may be operated as one touch electrode in the equivalent potential state in touch driving.

[0261] Similarly, two or more electrodes TE(i)2 and TE(i-2)2 connected by a second signal line SL_2A may be separated from each other by another electrode TE(i-1)2. Moreover, two or more electrodes TE(i)2 and TE(i-2)2 connected by a second signal line SL_2A may be separately arranged in two or more non-adjacent electrode rows (i-th electrode row and i-2-th electrode row). Moreover, two or more electrodes TE(i)2 and TE(i-2)2 connected by a second signal line SL_2A are separated from each other by another electrode TE(i-1)2 but can be operated as one touch electrode in the equivalent potential state in a touch drive.

[0262] As described above, two or more electrodes connected by a signal line are separated from each other by another electrode and arranged in different electrode rows, but they are electrically connected to each other and can function as a touch electrode.

[0263] A plurality of electrode rows included in a touch-sensitive panel TSP may have odd-numbered electrode rows and even-numbered electrode rows.

[0264] Referring to the Fig. 16 to 19, the electrodes (vertical electrode) arranged in the i-8th, i-6th, i-4th, i-2th, i-th, i+2th, i+4th, and i+6th electrode rows, which may be odd-numbered or even-numbered electrode rows of odd-numbered electrode rows and even-numbered electrode rows, are grouped four vertically, and one signal line may be connected to each group (each touch electrode).

[0265] According to the example of Fig. 18, the electrodes arranged in the i-8th, i-6th, i-4th, i-2th, i-th, i+2th, i+4th and i+6th electrode rows are grouped four by four, thereby forming a plurality of touch electrodes V1-1, V2-1, ..., V8-1, V1-2, V2-2, ..., V8-2, V1-1, V2-1, ..., V8-1, V3-3, V4-3, V7-3, V8-3, ....

[0266] The plurality of touch electrodes V1-1, V2-1, ..., V8-1, V1-2, V2-2, ..., V8-2, V1-1, V2-1, ..., V8-1, V3-3, V4-3, V7-3, V8-3, ... are similar to the touch electrodes TE_V1, TE_V2, TE_V3 and TE_V4 in the matrix-type touch-sensitive panel TSP of Fig. 4.

[0267] Referring to the Fig. 16 to 19, the electrodes (horizontal electrode) arranged in the i-7th, i-5th, i-3th, i-1th, i+1th, i+3th, i+5th, and i+7th electrode rows, which may be even-numbered or odd-numbered electrode rows of odd-numbered electrode rows and even-numbered electrode rows, may be individually connected to signal lines without being grouped.

[0268] According to the example of Fig. 14, the electrodes arranged in the i-7th, i-5th, i-3th, i-1th, i+1th, i+3th, i+5th and i+7th electrode rows individually form touch electrodes H1-1, H1-2, H2-1, H2-2, H3-1, H3-2, H3-3, H4-1, H4-2, H4-3, H5-1, H5-2, H6-1, H6-2, H7-1, H7-2, H7-3, H8-1, H8-2, H8-3, ....

[0269] The individual touch electrodes H1-1, H1-2, H2-1, H2-2, H3-1, H3-2, H3-3, H4-1, H4-2, H4-3, H5-1, H5-2, H6-1, H6-2, H7-1, H7-2, H7-3, H8-1, H8-2, H8-3, ... are similar to the horizontal touch electrodes TE_H1, TE_H2, TE_H3, TE_H4 in the matrix-type touch-sensitive panel TSP of Fig. 4.

[0270] Referring to the Fig. 16 to 19, a plurality of signal lines SL are each arranged in the column direction and can each overlap one or more electrodes.

[0271] Referring to the Fig. 16 to 19 may all be arranged from a plurality of electrodes in the same layer.

[0272] Referring to the Fig. 16 to 19, a plurality of signal lines SL may be arranged in a layer different from a plurality of electrodes with an insulating layer INS therebetween.

[0273] Referring to the Fig. 16 to 19, in the structure described above, assuming that the area obtained by connecting a 1 / 4 point of a horizontal electrode (e.g., TE(i-7)1) and a vertical electrode (e.g., TE(i-8)1) is one touch unit TU, the area corresponding to a touch unit of four rows by four columns (4*4 TU, i.e., sixteen TUs) is defined as one pattern unit PU. A touch-sensitive panel TSP is formed by repeatedly forming the pattern unit PU.

[0274] Fig. 19 is a diagram in which touch electrodes V1-1, V2-1, ..., V8-1, V1-2, V2-2, ..., V8-2, V1-1, V2-1, ..., V8-1, V3-3, V4-3, V7-3, V8-3, ... obtained by grouping vertical electrodes are indicated by vertical lines, and touch electrodes corresponding to horizontal electrodes H1-1, H1-2, H2-1, H2-2, H3-1, H3-2, H3-3, H4-1, H4-2, H4-3, H5-1, H5-2, H6-1, H6-2, H7-1, H7-2, H7-3, H8-1, H8-2, H8-3, ... are indicated by horizontal lines in Fig. 18 indicated.

[0275] Referring to Fig. 19, when multiple touches T1 and T2 occur at two or more points n1 and n2, the possibility that the touch detection circuit TSC mistakes points other than the actual touch points n1 and n2 for touch points can be eliminated or reduced. That is, according to a woven-type touch-sensitive panel TSP, a phantom phenomenon can be prevented or reduced.

[0276] In a woven-type touch-sensitive panel (TSP), since the paths through which charge is transferred by multiple touches T1 and T2 at actual touch points n1 and n2 are interrupted, charge transfer causing a phantom phenomenon is prevented. Accordingly, a phantom phenomenon can be prevented.

[0277] When a first touch T1 occurs at point n1 and a second touch T2 occurs simultaneously at point n2 (a point different from point n1), charge from the first touch T1 is not transferred to the surroundings because two horizontal touch electrodes H3-1 and H3-2 have been interrupted and two vertical touch electrodes V3-1 and V3-2 have been interrupted. Accordingly, a phantom phenomenon can be prevented.

[0278] According to the woven type touch panel TSP of the Fig. 12 to 15 and the touch-sensitive panel TSP of the woven type of the Fig. 16 to 19, as described above, a phantom phenomenon can be prevented or reduced even in a multiple touch.

[0279] In addition, in the touch-sensitive panel TSP of the woven type of the Fig. 12 to 19 sixty-four contact units TU. This means that sixty-four contact coordinate points exist.

[0280] However, assuming the sizes of the touch electrodes are all the same, the number of touch electrodes can be reduced to 32 (H1-1, H2-1, ..., H8-1, H1-2, H2-2, ..., H8-2, V1-1, V2-1, ..., V8-1, V1-2, V2-2, ..., V8-2). Accordingly, the number of signal lines and the number of touch channels can also be significantly reduced to 32.

[0281] Fig. 20 and Fig. 21 are diagrams showing a connection structure between some electrodes in an upper edge region and a lower edge region of an active area A / A in a woven-type touch panel TSP having repeating 2*2 TUs of a touch-sensitive display device according to embodiments of the present disclosure.

[0283] Among the plurality of electrodes, some electrodes TE_U1 and TE_U2 arranged in the first electrode row (or second electrode row) of the upper edge region of the active region A / A do not have electrodes connected to each other in groups around them. Some electrodes TE_D1 and TE_D2 arranged in the n-1st electrode row (or nth electrode row) of the lower edge region of the active region A / A do not have electrodes connected to each other in groups around them.

The upper contact hole CNT_U2 of the third signal line SL_UD2 is connected to the electrode TE_U2, and the lower contact hole CNT_D2 of the third signal line SL_UD2 is connected to the electrode TE_D2.

[0286] The third signal lines SL_UD1 and SL_UD2 in the active region A / A may overlap the electrodes arranged between some electrodes TE_U1 and TE_U2 arranged in the first electrode row (or second electrode row) and some electrodes TE_D1 and TE_D2 arranged in the n-1-th electrode row (n-th electrode row).

[0287] In another way, as in Fig. 21, two or more electrodes TE_U1 and TE_U2 of the electrodes arranged in the first electrode rows (or second electrode rows) of the upper edge region of the active region A / A of the plurality of electrodes may be electrically connected by a fourth signal line SL_OU which takes a detour through an upper outer region N / A of the active region A / A.

[0292] Referring to the Fig. 22 and Fig. 23, a plurality of electrodes may be arranged in the active region A / A. Two or more leftmost electrodes TE_L1 and TE_L2 of the electrodes arranged in the left edge region of the active region A / A among the plurality of electrodes do not have electrodes connected to each other in groups around them. Furthermore, two or more rightmost electrodes TE_R1 and TE_R2 of the electrodes arranged in the right edge region of the active region A / A among the plurality of electrodes do not have electrodes connected to each other in groups around them.

[0293] According to a Fig. 22, two or more leftmost electrodes TE_L1 and TE_L2 of the electrodes arranged in the left edge region of the active region A / A of the plurality of electrodes may be electrically connected by a sixth signal line SL_L12 in the active region A / A through contact holes CNT_L1 and CNT_L2.

The two or more electrodes TE_L1 and TE_L2 are electrically connected by the sixth signal line SL_OL, which takes a detour through the left outer region N / A of the active area A / A.

The two or more electrodes TE_R1 and TE_R2 are electrically connected by the seventh signal line SL_OR, which takes a detour through the right outer region N / A of the active area A / A.

[0299] A method for controlling and detecting the by reference to the Fig. 6 to 23 will be described below. However, for the convenience of description, the case where 2*2 touch units TU of the Fig. 6 to 11 form a sample unit PU.

[0300] Fig. 24 and Fig. 25 are diagrams illustrating a driving method of a touch-sensitive display device according to embodiments of the present disclosure. However, the driving method refers to the structure of Fig. 8 to simplify the description.

[0301] Referring to the Fig. 24 and Fig. 25, the electrodes arranged in the i-4th, i-2nd, i-th, and i+2nd electrode rows among a plurality of electrodes are grouped two by two, thereby forming a plurality of touch electrodes V1-1, V2-1, V3-1, V4-1, V1-2, V2-2, V3-2, V4-2, V2-3, V4-3, .... The electrodes arranged in the i-3rd electrode row, i-1st electrode row, i+1st electrode row, and i+3rd electrode row among the plurality of electrodes respectively form touch electrodes H1-1, H1-2, H2-1, H2-2, H2-3, H3-1, H3-2, H4-1, H4-2, H4-3, ....

[0302] Accordingly, with reference to the Fig. 24 and Fig. 25, the touch detection circuit TSC of a touch-sensitive display device according to embodiments of the present disclosure can detect one or more touch electrodes. Accordingly, the touch detection circuit TSC can detect two or more electrodes grouped into one touch electrode among a plurality of electrodes.

[0303] The touch-sensitive display device according to embodiments of the present disclosure may detect touches based on self-capacitance or may detect touches based on mutual capacitance.

[0304] When the touch-sensitive display device according to embodiments of the present disclosure detects touches based on self-capacitance, the touch detection circuit TSC may detect a touch detection signal by supplying a touch drive signal TSD to the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+2)1 in the i+2-th electrode row. The touch detection circuit TSC may detect a touch detection signal by supplying a touch drive signal TDS to the first electrode TE(i+1)1 in the i+1-th electrode row, which is arranged between the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+2)1 in the i+2-th electrode row.

[0305] The touch drive signal TDS described here, which is a signal having a variable voltage level, may be a signal having multiple pulses. The touch drive signal TDS has a predetermined frequency and may oscillate at a predetermined amplitude.

[0306] When the touch-sensitive display device according to embodiments of the present disclosure detects touches based on mutual capacitance, it may detect a capacitance between the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+1)1 in the i+1-th electrode row, and may detect a capacitance between the first electrode TE(i+2)1 in the i+2-th electrode row and the first electrode TE(i+1)1 in the i+1-th electrode row.

[0307] For this purpose, the touch detection circuit TSC may supply a touch drive signal to the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+2)1 in the i+2-th electrode row, and may detect a touch detection signal from the first electrode TE(i+1)1 in the i+1-th electrode row arranged between the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+2)1 in the i+2-th electrode row.

[0308] Alternatively, the touch detection circuit TSC may supply a touch drive signal to the first electrode TE(i+1)1 in the i+1-th electrode row arranged between the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+2)1 in the i+2-th electrode row, and may detect a touch detection signal from the first electrode TE(i)1 in the i-th electrode row and the first electrode TE(i+2)1 in the i+2-th electrode row.

The electrodes arranged in the i-4th, i-2nd, i-th, and i+2nd electrode lines are grouped, whereby a no-load drive signal LFDS for preventing parasitic capacitance can be applied to all of a plurality of touch electrodes V1-1, V2-1, V3-1, V4-1, V1-2, V2-2, V3-2, V4-2, .... The no-load drive signal LFDS may correspond to the touch drive signal TDS in frequency and amplitude and may be a signal that is the same as the touch drive signal TDS.

[0311] As in Fig. As shown in Fig. 24, the electrodes arranged in the i-4th, i-2th, i-th, and i+2th electrode lines are grouped, whereby the plurality of touch electrodes V1-1, V2-1, V3-1, V4-1, V1-2, V2-2, V3-2, V4-2, ... can be simultaneously detected by simultaneously receiving a touch drive signal TDS. A no-load drive signal LFDS for preventing parasitic capacitance can be simultaneously applied to all of the touch electrodes H1-1, H2-1, H3-1, H4-1, H1-2, H2-2, H3-2, H4-2, ... in which the electrodes arranged in the i-3th electrode line, the i-1st electrode line, the i+1st electrode line, and the i+3th electrode line are respectively formed. The no-load drive signal LFDS may correspond to the touch drive signal TDS in frequency and amplitude and may be a signal that is the same as the touch drive signal.

[0312] As in Fig. As shown in Figure 25, the touch electrodes H1-1, H2-1, H3-1, H4-1, H1-2, H2-2, H3-2, H4-2, ..., in which the electrodes arranged in the i-3th electrode line, the i-1st electrode line, the i+1st electrode line, and the i+3th electrode line are respectively formed, can be grouped, thereby being able to be sequentially driven and detected. For example, the touch electrodes H1-1, H2-1, H3-1, and H4-1 can be simultaneously detected by first simultaneously receiving a touch drive signal. Next, the touch electrodes H1-2, H2-2, H3-2, and H4-2 can be simultaneously detected by simultaneously receiving a touch drive signal TDS. A no-load drive signal LFDS to prevent parasitic capacitance can be applied to all the other electrodes to which no touch drive signal TDS has been applied.

[0313] As in Fig. As shown in Figure 25, the electrodes arranged in the i-4th, i-2th, i-th, and i+2th electrode lines are grouped, whereby the plurality of touch electrodes V1-1, V2-1, V3-1, V4-1, V1-2, V2-2, V3-2, V4-2, ... can be grouped, thereby being able to be driven and detected sequentially. For example, the touch electrodes V1-1, V2-1, V3-1, and V4-1 can be detected simultaneously by first simultaneously receiving a touch drive signal. Next, the touch electrodes V1-2, V2-2, V3-2, and V4-2 can be detected simultaneously by simultaneously receiving a touch drive signal TDS. A no-load drive signal LFDS to prevent parasitic capacitance can be applied to all the other electrodes to which no touch drive signal TDS has been applied.

[0314] In contrast, a touch-sensitive display device according to embodiments of the present disclosure may perform display control for image display during a display period and may perform touch control during a touch period different from the display period.

[0315] During the display period, a plurality of electrodes may be floating or may receive a predetermined voltage or a voltage adjusted to improve display performance may be applied.

[0316] A plurality of electrodes may function as a common electrode, to which a common voltage required for display control is applied. In this case, a common voltage may be applied to the plurality of electrodes during the display period.

[0317] The touch detection circuit TSC may supply a touch drive signal TDS to two or more electrodes grouped into one touch electrode among the plurality of electrodes during the touch period.

[0318] During the touch period, when a touch drive signal TDS is supplied to two or more electrodes grouped as one touch electrode among the plurality of electrodes, in order to prevent unnecessary parasitic capacitance between a data line and a touch electrode, a data signal (not a data signal for image display) having the same amplitude and phase as the touch drive signal TDS may be applied to a plurality of data lines arranged in the display panel DISP.

[0319] A touch-sensitive display panel according to embodiments of the present disclosure can independently perform display control for image display and touch control for touch detection. Alternatively, the touch-sensitive display device can simultaneously perform display control for image display and touch control for touch detection.

[0320] The multiple electrodes are touch electrodes for touch control, but they can also be common electrodes to which a common voltage necessary for display control is applied.

[0321] Accordingly, in order to perform display driving and touch driving simultaneously, when the touch detection circuit TSC supplies a touch driving signal TDS to two or more electrodes to be grouped into one touch electrode among the plurality of electrodes, the data signal applied to the plurality of data lines arranged in the display panel may be a signal generated by connecting the data voltage for image display and the touch driving signal TDS. Furthermore, the gate signal applied to the plurality of gate lines arranged in the display panel may be a signal obtained by combining gate voltages VGH and VGL for driving gate lines and a touch driving signal TDS.

[0322] Various control operations of a touch-sensitive display device according to embodiments of the present disclosure are described below. The various control operations may include: a display control for displaying an image, a touch control (finger touch control) for detecting touches by fingers, etc., and a touch control (pen touch control) for detecting touches by a pen, etc.

[0323] In the following description, it is assumed that in a touch-sensitive panel TSP of the woven type, for example, as shown in the Fig. 7 and Fig. 8, a plurality of touch electrodes V1-1, V2-1, V3-1, V4-1, V1-2, V2-2, V3-2, V4-2, V2-3, V4-3, ... are formed by grouping in pairs the electrodes TE(i-4)1 ~ TE(i-4)4, TE(i-2)1 ~ TE(i-2)4, TE(i)1 ~ TE(i)4 and TE(i+2)1 ~ TE(i+2)4 arranged in the 1-4th, 1-2th, i-th and i+2th electrode rows, and the electrodes TE(i-3)1 ~ TE(i-3)2, TE(i-1)1 ~ TE(i-1)3, TE(i+1)1 ~ TE(i+1)2, TE(i+3)1 ∼ TE(i+3)3 arranged in the i-3th electrode row, i-1th electrode row, i+1th electrode row and i+3th electrode row respectively drive a plurality of touch electrodes V1-1, V2-1, V3-1, V4-1, V1-2, V2-2, V3-2, V4-2, V2-3, V4-3, ... and H1-1, H1-2, H2-1, H2-2, H2-3, H3-1, H3-2, H4-1, H4-2, H4-3, ... when a plurality of touch electrodes H1-1, H1-2, H2-1, H2-2, H2-3, H3-1, H3-2, H4-1, H4-2, H4-3, ... is formed.

[0324] In the following description, for the sake of simplicity of description, the plurality of touch electrodes V1-1, V2-1, V3-1, V4-1, V1-2, V2-2, V3-2, V4-2, V2-3, V4-3, ... and H1-1, H1-2, H2-1, H2-2, H2-3, H3-1, H3-2, H4-1, H4-2, H4-3, ... are referred to as a plurality of touch electrodes TE.

[0325] Fig. 26 is a diagram illustrating a time division multiplexing (TDD) method of a touch display device according to embodiments of the present disclosure.

[0326] Referring to Fig. 26, a touch-sensitive display device according to embodiments of the present disclosure can alternately perform displaying and touch sensing. The above-described method of alternately advancing a display drive for displaying and a touch drive for touch sensing is referred to as a time-division multiplexing drive method.

[0327] According to the time-division multiplexing control method, a display period for displaying and a touch detection period for touch detection are alternately shown. During the display period, the touch-sensitive display device can perform display control. During the touch detection period, the touch-sensitive display device can perform touch control.

[0328] As an example of the time-division multiplexing method, one frame time may be divided into one display period and one touch detection period. As another example of the time-division multiplexing method, one frame time may be divided into two or more display periods and two or more touch detection periods.

[0329] Referring to Fig. 26, according to the time-division multiplexing method, a touch drive signal TDS can be applied to one or more of a plurality of touch electrodes TE during the touch detection period. A plurality of data lines and a plurality of gate lines may not be driven in this process.

[0330] In this case, unnecessary parasitic capacitance may be generated due to a potential difference between the touch electrodes TE, to which the touch drive signal TDS has been applied, and one or more surrounding data lines. Such unnecessary parasitic capacitance may impair touch sensitivity by increasing the RC delay for a corresponding touch electrode TE and a touch line TL connected to the touch electrode TE.

[0331] Furthermore, unnecessary parasitic capacitance may be generated due to a potential difference between the touch electrodes TE, to which the touch drive signal TDS has been applied, and one or more surrounding gate lines. Such unnecessary parasitic capacitance may impair touch sensitivity by increasing the RC delay for a corresponding touch electrode TE and a touch line TL connected to the touch electrode TE.

[0332] Furthermore, unnecessary parasitic capacitance may also be generated due to a potential difference between the touch electrodes TE to which the touch drive signal TDS has been applied and one or more surrounding touch electrodes. Such unnecessary parasitic capacitance may impair touch sensitivity by increasing the RC delay for a corresponding touch electrode TE and a touch line TL connected to the touch electrode TE.

[0333] The previously mentioned RC delay can be referred to as a time constant or a load.

[0334] To remove the load, a touch-sensitive display device according to embodiments of the present disclosure may perform a no-load drive (LFD) during a touch detection period.

[0335] A touch-sensitive display device according to embodiments of the present disclosure may apply a no-load drive signal LFDS as a data signal Vdata to all or some data lines in which parasitic capacitance may be generated when a touch drive signal TDS is applied to all or some of a plurality of touch electrodes TE during no-load driving.

[0336] A touch-sensitive display device according to embodiments of the present disclosure may apply a no-load drive signal LFDS as a gate signal Vgate to all gate lines or some gate lines in which parasitic capacitance may be generated when a touch drive signal TDS is applied to all or some of a plurality of touch electrodes TE during no-load driving.

[0337] A touch-sensitive display device according to embodiments of the present disclosure may apply a no-load drive signal LFDS to all other touch electrodes TE or some other touch electrodes TE in which a parasitic capacitance may be generated when a touch drive signal TDS is applied to some of a plurality of touch electrodes TE during no-load driving.

[0338] The no-load drive signal LFDS may be a touch drive signal or may be a signal having signal characteristics the same as or similar to those of a touch drive signal.

[0339] For example, the frequency and phase of the no-load drive signal LFDS and the frequency and phase of a touch drive signal TDS may be the same or may be the same within a specified tolerance range. The amplitude of the no-load drive signal LFDS and the amplitude of a touch drive signal TDS may be the same or may be the same within a specified tolerance range, and depending on the case, an unintended difference may occur.

[0340] Fig. 27 is a diagram illustrating a time-free driving (TFD) method of a touch-sensitive display device according to embodiments of the present disclosure.

[0341] Referring to Fig. 27, a touch-sensitive display device according to embodiments of the present disclosure can independently perform display and touch detection. The above-described driving method for independently performing display control for display and touch control for touch detection is called a time-free driving method.

[0342] According to the time-free control method, a display control for displaying and a touch control for touch detection can be driven simultaneously. During a certain period, only a display control for displaying or only a touch control for touch detection can be driven.

[0343] Fig. 28 is a diagram showing three cases (Cases 1, 2, and 3) of time-free driving when a touch-sensitive display device according to embodiments of the present disclosure performs time-free driving, Fig. 29 is a diagram showing different timings of a finger detection F / S and a pen detection P / S according to the time-free driving method in a touch-sensitive display device according to embodiments of the present disclosure, and Fig. 30 is a diagram showing a touch drive signal TDS for each of three cases (cases 1, 2, and 3) of timeless driving in a touch-sensitive display device according to embodiments of the present disclosure.

[0344] According to the case 1 of time-free driving, a touch-sensitive display device can simultaneously drive a display drive and a touch drive.

[0345] In Case 1, the touch-sensitive display device may supply a touch drive signal TDS having a variable voltage to a touch electrode TE to perform touch driving.

[0346] In the following description, the touch drive signal TDS applied to a touch electrode TE in Case 1 is referred to as a first touch drive signal TDS1. The first touch drive signal TDS1 has a first amplitude AMP1.

[0347] In Case 1, the touch-sensitive display device can detect a touch by a finger contact on the touch-sensitive panel TSP by performing a touch control. This touch detection is referred to as finger detection.

[0348] Alternatively, in Case 1, the touch-sensitive display device can detect a touch by a finger or stylus when the finger or stylus approaches the touch-sensitive panel TSP without making contact with the touch-sensitive panel TSP by performing touch control. This touch detection is referred to as hover detection.

[0349] According to case 2 of the time-free control, the touch-sensitive display device can only perform one display control.

[0350] In Case 2, the touch-sensitive display device does not perform general touch control because there is no need to detect a touch by a finger. That is, the touch-sensitive display device does not supply a touch control signal TDS, which has a variable voltage, to a plurality of touch electrodes TE arranged in the touch-sensitive panel TSP.

[0351] In Case 2, the touch-sensitive display device may supply a touch drive signal TDS having a DC voltage. In the following description, the touch drive signal TDS applied to a touch electrode TE in Case 2 is referred to as a second touch drive signal TDS2.

[0352] In Case 2, the touch-sensitive display device can detect a stylus by receiving a stylus signal output from a stylus through a touch electrode TE. As a result of the stylus detection, the touch-sensitive display device can determine the position, inclination, pressure (pen pressure) of the stylus, or various additional information.

[0353] According to case 3 of time-free control, a touch-sensitive display device can only perform touch control.

[0354] In case 3, the touch-sensitive display device may supply a touch drive signal TDS having a variable voltage to a touch electrode TE to perform touch driving.

[0355] In the following description, the touch drive signal TDS applied to a touch electrode TE in Case 3 is referred to as a third touch drive signal TDS3. The third touch drive signal TDS3 has a third amplitude AMP3 that is different from the first amplitude AMP1.

[0356] In Case 3, the touch-sensitive display device can perform a touch by a contact of a finger on the touch-sensitive panel TSP by performing a touch control.

[0357] Referring to Fig. 28, in the touch-sensitive display device, case 1 of three cases (cases 1, 2, and 3) of time-free driving may proceed to an active time, and case 3 may proceed to an idle time. The active time may correspond to the time at which an image of a frame is displayed, and the idle time may correspond to the time required until an image of the next frame begins to be displayed after the previous image of a frame is displayed.

[0358] Referring to Fig. 28 Case 1 may change to Case 2 during the active period.

[0359] Referring to Fig. 28, during the active time, the touch-sensitive display device may pause a touch control for finger detection while both a display control and a touch control (progresses in case 1) are performed (ie, changes from case 1 to case 2).

[0360] In cases 1 and 3, in the touch control for finger detection, touch control signals TDS1 and TDS3 having an amplitude AMP1 and AMP3, respectively, can be applied to a touch electrode TE.

[0361] In case 2, for pen detection, a touch drive signal TDS2 having a DC voltage can be applied to a touch electrode TE.

[0362] Referring to Fig. 30, the first amplitude AMP1 of the first touch drive signal TDS1 applied to a touch electrode TE when performing touch drive with display drive (case 1) may be smaller than the third amplitude AMP3 of the third touch drive signal TDS3 applied to a touch electrode TE when performing only touch drive (case 3).

[0363] The first amplitude AMP1 of the first touch drive signal TDS1 applied to a touch electrode TE during the active time may be smaller than the third amplitude AMP3 of the third touch drive signal TDS3 applied to a touch electrode TE during the idle time.

[0364] Referring to the Fig. 28 and Fig. 30 During the active time, the touch driver circuit TDC may supply a first touch drive signal TSD1 having a first amplitude AMP1 or a second touch drive signal TDS2 corresponding to a DC voltage to a plurality of touch electrodes TE.

[0365] Referring to the Fig. 28 and Fig. 30, during the idle time, the touch driver circuit TDC may supply a third touch drive signal TDS3 having a third amplitude AMP3 to one or more of a plurality of touch electrodes TE.

[0366] A control corresponding to case 1 can proceed during a frame or can proceed only during a period of time within a frame. A control corresponding to case 2 can proceed during all frames or some frames and can proceed only during a period of time within the frames. In a control corresponding to case 3, a control for finger detection can proceed or a control for pen detection can proceed.

[0367] Referring to Fig. 29, in a touch-sensitive display device according to embodiments of the present disclosure, according to the time-free driving method, a finger detection F / S and a pen detection P / S may be performed at different times.

[0368] For example, as in the i-th frame, only one display control may proceed for display without finger detection F / S and pen detection P / S for one frame. This may correspond to Case 2 without pen detection P / S.

[0369] Furthermore, in the j-th frame, for a frame, a finger detection F / S may only proceed for a necessary time period in a frame time. This may correspond to Case 1. Furthermore, for a frame, a pen detection P / S may only proceed for a necessary time period in a frame time. This may correspond to Case 2. Furthermore, for a frame, a finger detection F / S and a pen detection P / S may both proceed for some non-overlapping time periods in a frame time.

[0370] For example, as in the k-th frame, a finger detection F / S and a stylus detection P / S may proceed for a frame during non-overlapping periods. In this case, the detection results of the finger detection F / S and stylus detection P / S can be discriminated by a predetermined algorithm or signal analysis according to a detection position by the touch control unit TCTR, etc.

[0371] In addition to these examples, display and touch detection (finger detection and / or stylus detection) may be independently advanced at different times.

[0372] Fig. 31 is a diagram arranging and showing the wavelength of main signals TDS1, Vdata, VGL_M, and VGH_M for each of three cases (Cases 1, 2, and 3) of time-free driving in a touch-sensitive display device according to embodiments of the present disclosure.

[0373] Cases 1 and 2 are control cases for an active time. Case 3 is a control case for an idle time.

[0374] For each of the three cases, a touch drive signal TDS applied to a touch electrode TE, a data signal Vdata applied to a data line, and an off-level gate voltage VGL and an on-level gate voltage VGH applied to a gate drive circuit GDC to generate a scan signal Vgate applied to a gate line are described.

[0375] In case 2, in which only one display drive proceeds during the active time, the touch drive signal TDS applied to the touch electrode TE is a second touch drive signal TDS2 having a DC voltage.

[0376] The data signal Vdata applied to a data line, which is a signal corresponding to an analog image signal obtained by digital-to-analog conversion of a digital signal for a display, may be a pixel voltage applied to a pixel electrode of a corresponding subpixel SP through the data line. However, the data signal Vdata may change to a voltage between a drive voltage AVDD and a base voltage AVSS.

[0377] The off-level gate voltage VGL and the on-level gate voltage VGH, which form the scan signal Vgate applied to the gate line, are corresponding DC voltages.

[0378] As described above, a touch electrode TE can function as a common electrode for display driving. Accordingly, in Case 2, where only display driving proceeds during the active time, the second touch drive signal TDS2 applied to a touch electrode TE corresponds to a common voltage for displaying.

[0379] Accordingly, in a corresponding subpixel SP, an electric field is generated between the pixel electrode and the touch electrode TE due to a voltage difference between the data signal Vdata applied to the pixel electrode through the data line and the second touch drive signal TDS2 corresponding to the common voltage applied to the touch electrode TE, whereby a desired light can emerge from the corresponding subpixel.

[0380] In case 3, in which only one touch drive proceeds during the idle time, the touch drive signal TDS applied to the touch electrode TE is a third touch drive signal TDS3 having a third amplitude AMP3.

[0381] During the idle time, the data line can receive a data signal Vdata corresponding to a DC voltage or can be in a floating state. During the idle time, the gate line can receive a scan signal Vgate formed from an off-level gate voltage VGL corresponding to a DC voltage or can be in a floating state.

[0382] During the idle time during which only touch driving proceeds, when no-load driving is performed, the data line and the gate line may be disturbed to be equal to the touch electrode TE in terms of a voltage characteristic.

[0383] According to the no-load drive, for the idle time, the data signal Vdata applied to the data line may be a third touch drive signal TDS3 or may be a no-load drive signal having signal characteristics (e.g., a phase, a frequency, and an amplitude) equal to or similar to those of the third touch drive signal TDS3.

[0384] Furthermore, during the idle time, the off-level gate voltage VGL applied to the gate line may be a third touch drive signal TDS3 or a no-load drive signal having signal characteristics (e.g., a phase, a frequency, and an amplitude) equal to or similar to those of the third touch drive signal TDS3.

[0385] In case 1, in which display driving and touch driving proceed simultaneously during the active time, the touch driving signal TDS applied to the touch electrode TE is a first touch driving signal TDS1 having a first amplitude AMP1.

[0386] In Case 1, since a display drive and a touch drive proceed simultaneously during the active time, the first touch drive signal TDS1 is a drive signal for touch detection and is also a common voltage Vcom for a display.

[0387] The first touch drive signal TDS1 applied to the touch electrode TE should have a predetermined voltage difference for a display from the data signal Vdata, which corresponds to a pixel voltage for a display.

[0388] In case 1, where a display drive and a touch drive proceed simultaneously, the first touch drive signal TDS1 performs two functions (a drive signal for touch detection and a common voltage for a display).

[0389] As described above, the common voltage Vcom corresponding to the first touch drive signal TDS1 is not a constant voltage but a variable voltage, so that there should be an additional voltage change by the first amplitude AMP1 of the first touch drive signal TDS1, which is different from the original voltage change, for indication in the data signal Vdata applied to the data line, so that the data line is not affected by the touch drive.

[0390] Accordingly, only the original voltage change for a display without the voltage change portion (ie, the first amplitude AMP1) of the first touch drive signal TDS1 exists in the voltage difference between the data signal Vdata, which corresponds to the pixel voltage, and the first touch drive signal TDS1, which corresponds to the common voltage Vcom. Accordingly, normal display may be possible.

[0391] Accordingly, the data signal Vdata in the case 1 in which a display drive and a touch drive proceed simultaneously may be a signal that is a combination of the data signal Vdata in the case (Case 2) in which only a display drive proceeds and the first touch drive signal TDS1.

[0392] In other words, the data signal Vdata in Case 1, where a display drive and a touch drive proceed simultaneously, may be a signal in which the original data signal Vdata in Case 2, where only a display drive proceeds, has been offset by the first touch drive signal TDS1. However, the data signal Vdata may be a voltage change between a drive voltage AVDD and a base voltage AVSS.

[0393] Accordingly, the voltage difference between the data signal Vdata and the first touch drive signal TDS1 in Case 1, in which a touch drive and a display drive proceed simultaneously, is equal to the voltage difference between the data signal Vdata and the second touch drive signal TDS2 in Case 2, in which only a display drive proceeds.

[0394] In case 1, a load-free control may be required because a touch control and a display control proceed simultaneously.

[0395] That is, in Case 1, since touch driving and display driving proceed simultaneously, it may be necessary to prevent generation of parasitic capacitance between a touch electrode TE and a data line due to touch driving and to prevent generation of parasitic capacitance between a touch electrode TE and a gate line due to touch driving.

[0396] As described above, in Case 1, since the touch electrode TE and the data line are disturbed according to a voltage change of the first touch drive signal TDS1, there is only a voltage difference for displaying without unnecessary parasitic capacitance due to touch drive between the touch electrode TE and the data line. This means that in Case 1, no-load drive for the data line is necessarily promoted.

[0397] In Case 1, the off-level gate voltage VGL and the on-level gate voltage VGH supplied to the gate drive circuit GDC so that the gate drive circuit GDC generates a scan signal SCAN applied to the gate line may each be a no-load drive signal having signal characteristics (e.g., a phase, a frequency, and an amplitude) equal to or similar to those of the third touch drive signal TDS3.

[0398] In the time-free driving, when a display drive and a touch drive proceed simultaneously and a touch drive signal TDS of a modulation signal type having a variable voltage level is applied to touch electrodes TE, the data voltage VDATA applied to data lines may be a signal type in which a touch drive signal TDS is added to the original voltage for image display (a type in which two signals are combined).

[0399] As an example, the data voltage VDATA is generated using a gamma voltage, which is a modulation signal type modulated to correspond to a touch drive signal TDS. Accordingly, the data voltage VDATA applied to the data lines may be a signal type that oscillates further from the original voltage for an image display by the amplitude of a touch drive signal TDS. In this case, the ground voltage applied to the display panel DISP may be a DC voltage.

[0400] As another example, the ground voltage applied to the display panel DISP is modulated to correspond to a touch drive signal TDS. Accordingly, the data voltage VDATA applied to the data lines may have a signal type that oscillates further from the original voltage change for an image display by the amplitude of the ground voltage applied to the display panel DISP. The amplitude of the ground voltage corresponds to the amplitude of the touch drive signal.

[0401] In time-free driving, when display driving and touch driving proceed simultaneously and a modulation signal type of a touch drive signal TDS having a variable voltage level is applied to touch electrodes TE, the scanning signal applied to gate lines may be a signal type in which a touch drive signal TDS is added to the gate voltage for image display (a type in which two signals are combined). The gate voltage may be an off-level gate voltage (e.g., VGL) that turns off the gate lines, or an on-level gate voltage (e.g., VGH) that turns on the gate lines.

[0402] As an example, the scan signal is generated using gate voltages VGH and VGL, which are modulation signal types modulated to correspond to a touch drive signal TDS. Accordingly, the scan signal applied to the gate lines may be a signal type that oscillates by the amplitude of a touch drive signal TDS from the gate voltages VGH and VGL for image display. In this case, the ground voltage applied to the display panel DISP may be a DC voltage.

[0403] As another example, the ground voltage applied to the display panel DISP is modulated to correspond to a touch drive signal TDS. Accordingly, the scanning signal applied to the gate lines may be a signal type that oscillates further by the amplitude of the ground voltage applied to the display panel DISP from the gate voltages VGH and VGL for image display. The amplitude of the ground voltage corresponds to the amplitude of the touch drive signal TDS.

[0404] Although some modes for time-free control have been described above, the present disclosure is not limited thereto and can be implemented in numerous ways.

[0405] The previously described “woven type” touch-sensitive panel TSP is again briefly described as a “modified matrix type” touch-sensitive panel TSP.

[0406] Fig. 32 is a diagram showing a woven type touch panel TSP of a touch display device according to embodiments of the present disclosure.

[0407] Referring to Fig. 32, a touch-sensitive panel TSP may include: four row electrode lines TEL_H1, TEL_H2, TEL_H3, and TEL_H4 arranged in the row direction, and four column electrode lines TEL_V1, TEL_V2, TEL_V3, and TEL_V4 arranged in the column direction.

[0408] This corresponds to the matrix-like touch-sensitive panel TSP in the Fig. 4 and Fig. 5, which is formed of touch electrodes TE_H1 ~ TE_H4 arranged in four rows and touch electrodes TE_V1 ∼ TE_V4 arranged in four columns.

[0409] However, in the touch-sensitive panel TSP of Fig. 32 the four row electrode lines TEL_H1, TEL_H2, TEL_H3 and TEL_H4 have each been interrupted at one or more points.

[0410] In detail, the four row electrode lines TEL_H1, TEL_H2, TEL_H3 and TEL_H4 include a first row electrode line (e.g., TEL_H1) and a second row electrode line (e.g., TEL_H2), wherein the first row electrode line (e.g., TEL_H1) and a second row electrode line (e.g., TEL_H2) have breakpoints at different row direction positions.

[0411] The first row electrode line TEL_H1 includes a touch electrode H1-1 (TE(i-3)1) and a touch electrode H1-2 (TE(i-3)2). The second row electrode line TEL_H2 includes a touch electrode H2-1 (TE(i-1)1), a touch electrode H2-2 (TE(i-1)2), and a touch electrode H2-3 (TE(i-1)3).

[0412] The separated point (break point) of the touch electrode H1-1 and the touch electrode H1-2 in the first row electrode line TEL_H1 is different in row direction position from the separated point (break point) of the touch electrode H2-1 and the touch electrode H2-2 in the second row electrode line TEL_H2.

[0413] The separated point (break point) of the touch electrode H1-1 and the touch electrode H1-2 in the first row electrode line TEL_H1 is different in a row direction position from the separated point (break point) of the touch electrode H2-2 and the touch electrode H2-3 in the second row electrode line TEL_H2.

[0414] Referring to Fig. 32, the four column electrode lines TEL_V1, TEL_V2, TEL_V3 and TEL_V4 have also been interrupted at one or more points.

[0415] In detail, the four column electrode lines TEL_V1, TEL_V2, TEL_V3 and TEL_V4 comprise a first column electrode line (e.g., TEL_V1) and a second column electrode line (e.g., TEL_V2), wherein the first column electrode line (e.g., TEL_V1) and a second column electrode line (e.g., TEL_V2) have breakpoints at different column direction positions.

[0416] The first column electrode line (e.g., TEL_V1) includes: a touch electrode V1-1 (in which an electrode TE(i-4)1 and an electrode TE(i-2)1 electrically connected to each other by a signal line have been grouped) and a touch electrode V1-2 (in which an electrode TE(i)1 and an electrode TE(i+2)1 electrically connected to each other by a signal line have been grouped).

[0417] The second column electrode line (e.g., TEL_V2) includes: a touch electrode V2-1 (in which an electrode TE(i-4)2 and another electrode have been grouped by being electrically connected by a signal line arranged inside or outside an active area A / A), a touch electrode V2-2 (in which an electrode TE(i-2)2 and an electrode TE(i)2, which are electrically connected to each other by a signal line, have been grouped), and a touch electrode V2-3 (in which an electrode TE(i+2)2 and another electrode have been grouped by being electrically connected by a signal line arranged inside or outside an active area A / A).

[0418] The separated point (break point) of the touch electrode V1-1 and the touch electrode V1-2 in the first column electrode line (e.g., TEL_V1) is different in a column direction position from the separated point (break point) of the touch electrode V2-1 and the touch electrode V2-2 in the second column electrode line (e.g., TEL_V2).

[0419] The separated point (break point) of the touch electrode V1-1 and the touch electrode V1-2 in the first column electrode line (e.g., TEL_V1) is different in a column direction position from the separated point (break point) of the touch electrode V2-2 and the touch electrode V2-3 in the second column electrode line (e.g., TEL_V2).

[0420] The break points in each of the four row electrode lines TEL_H1, TEL_H2, TEL_H3 and TEL_H4 and each of the four column electrode lines TEL_V1, TEL_V2, TEL_V3 and TEL_V4 prevent charge transfer, thereby being able to prevent a phantom phenomenon in a multi-touch.
