[0044] like Figure 1As shown, the apparatus for sensing stretching according to an embodiment of the present disclosure may include a light-emitting display panel 10, the light-emitting display panel 10 including a display area DA for displaying an image and a non-display area NDA arranged outside the display area DA, a gate driver 20 that provides a gate signal GS to a plurality of gate lines GL1 to GLg arranged in the display area DA of the light-emitting display panel 10, a data driver 30 that provides a data voltage Vdata to a plurality of data lines DL1 to DLd arranged in the display area DA of the light-emitting display panel 10, a touch driver 50 that provides a touch drive signal to a touch electrode arranged in the light-emitting display panel 10, a stretch driver 60 that provides a stretch drive signal to a stretch electrode arranged in the light-emitting display panel 10, a control driver 40 that controls driving of the gate driver 20, the data driver 30, the touch driver 50 and the stretch driver 60, and a power supply unit that supplies power to the control driver 40, the gate driver 20, the data driver 30, the touch driver 50, the stretch driver 60 and the light-emitting display panel 10.

[0045] First, the light-emitting display panel 10 may include a display panel 200 that displays an image, a touch panel 300 in which touch electrodes for touch sensing are provided in the display panel 200, and a stretching panel 100 in which electrodes for stretching sensing are provided. However, the light-emitting display panel 10 may include only the display panel 200 and the stretching panel 100.

[0046] The display panel 200 may include a display area DA and a non-display area NDA. Gate lines GL1 to GLg, data lines DL1 to DLd, and pixels P may be arranged in the display area DA. Thus, an image may be displayed in the display area DA. Here, g and d are natural numbers. The non-display area NDA may surround the outer periphery of the display area DA.

[0047] like Figure 2 As shown, the pixel P included in the display panel 200 may include a pixel driving circuit PDC and a light emitting device ED, the pixel driving circuit PDC including a switching transistor Tsw1, a storage capacitor Cst, a driving transistor Tdr and a sensing transistor Tsw2, and the light emitting device ED is connected to the pixel driving circuit PDC.

[0048] A first terminal of the driving transistor Tdr may be connected to a first voltage supply line through which a first voltage EVDD is supplied, and a second terminal of the driving transistor Tdr may be connected to the light emitting device ED.

[0049] A first terminal of the switching transistor Tsw1 may be connected to the data line DL, a second terminal of the switching transistor Tsw1 may be connected to the gate of the driving transistor Tdr, and a gate of the switching transistor Tsw1 may be connected to the gate line GL.

[0050] The data voltage Vdata may be provided through the data line DL from the data driver 30. The gate signal GS may be provided through the gate line GL from the gate driver 20. The gate signal GS may include a gate pulse GP for turning on the switching transistor Tsw1 and a gate-off signal for turning off the switching transistor Tsw1.

[0051] The sensing transistor Tsw2 may be configured to measure a threshold voltage or charge (e.g., electron) mobility of the driving transistor Tdr, or to provide a reference voltage Vref to the pixel driving circuit PDC. A first terminal of the sensing transistor Tsw2 may be connected to a second terminal of the driving transistor Tdr and the light-emitting device ED, a second terminal of the sensing transistor Tsw2 may be connected to a sensing line SL through which the reference voltage Vref is provided, and a gate of the sensing transistor Tsw2 may be connected to a sensing control line SCL through which a sensing control signal SCS is provided.

[0052] The sensing line SL may be connected to the data driver 30, and may be connected to the power supply unit through the data driver 30. For example, a reference voltage Vref provided from the power supply unit may be provided to the pixel through the sensing line SL, a sensing signal transmitted from the pixel P may be converted into a digital sensing signal in the data driver 30, and the digital sensing signal may be transmitted to the control driver 40.

[0053] The light emitting device ED may include a first electrode supplied with a first voltage EVDD through a driving transistor TDR, a second electrode connected to a second voltage supply line PLB through which a second voltage is supplied, and a light emitting layer disposed between the first electrode and the second electrode. The first electrode may be an anode, and the second electrode may be a cathode.

[0054] The structure of the pixel P applied to the apparatus for sensing stretching according to an embodiment of the present disclosure is not limited to Figure 2 Therefore, the structure of the pixel P can be changed into various shapes.

[0055] The touch panel 300 may perform a function of sensing a touch, and to this end, may include touch electrodes.

[0056] For example, when the touch panel 300 uses a mutual method, the touch electrode may include at least one touch drive electrode and at least one touch receiving electrode. In this case, the touch driver 50 may provide a touch drive signal to the touch drive electrode, and may use the touch sensing signal received from the touch receiving electrode to determine whether a touch is present through the touch drive signal.

[0057] In addition, when the touch panel 300 senses a touch caused by the electronic pen, the touch driver 50 can provide an uplink signal to the touch drive electrode and determine whether a touch is present by using a downlink signal received from the electronic pen through the touch receiving electrode. In this case, the uplink signal can be a touch drive signal.

[0058] In addition, when the touch panel 300 uses the self-capture method, at least one touch electrode may be provided in the touch panel 300. In this case, the touch driver 50 may provide a touch driving signal to the touch electrode and may determine whether a touch is present by using a touch sensing signal received from the touch electrode.

[0059] Hereinafter, for convenience of description, an apparatus for sensing stretch including the touch panel 300 using the mutual method will be described as an example of an apparatus for sensing stretch according to an embodiment of the present disclosure.

[0060] In this case, the touch driving electrodes provided in the touch panel 300 may be connected to the touch driver 50 through the touch driving electrode lines 31 , and the touch receiving electrodes provided in the touch panel may be connected to the touch driver 50 through the touch receiving electrode lines 32 .

[0061] The stretch panel 100 can sense whether it is stretched, whether it is bent, and whether it is under tensile stress. For this purpose, the stretch panel 100 can include three types of stretch electrodes. In the following description, stretch can refer to bending or tensile stress.

[0062] The three types of stretch electrodes may include drive electrodes, single receive electrodes, and cross receive electrodes.

[0063] The driving electrodes may be connected to the stretch driver 60 via driving electrode lines TXL, the single receiving electrodes may be connected to the stretch driver 60 via single receiving electrode lines RX_XL, and the cross receiving electrodes may be connected to the stretch driver 60 via cross receiving electrode lines RX_YL.

[0064] The control driver 40 can realign the input image data Ri, Gi, Bi transmitted from the external system 90 by using the timing synchronization signal TSS transmitted from the external system 90, and can generate a data control signal DCS to be provided to the data driver 30 and a gate control signal GCS to be provided to the gate driver 20.

[0065] For this reason, Figure 3As shown, the control driver 40 may include: a data aligner 430 that realigns the input image data Ri, Gi, and Bi to generate the image data Data, a control signal generator 420 that generates the gate control signal GCS and the data control signal DCS by using the timing synchronization signal TSS, an input unit 410 that transmits the timing synchronization signal TSS transmitted from the external system 90 to the control signal generator 420 and transmits the input image data Ri, Gi, and Bi transmitted from the external system 90 to the data aligner 430, and an output unit 440 that provides the image data Data generated by the data aligner 430 and the data control signal DCS generated by the control signal generator 420 to the data driver 30, and provides the gate control signal GCS generated by the control signal generator 420 to the gate driver 20.

[0066] The control signal generator 420 may generate a power control signal provided to the power supply unit.

[0067] The control signal generator 420 may generate a touch control signal provided to the touch driver 50 .

[0068] The control signal generator 420 may generate a stretch control signal provided to the stretch driver 60 .

[0069] The control driver 40 may further include a storage unit 450 for storing various information. The storage unit 450 may be included in Figure 3 The control driver 40 is shown, but can be separated from the control driver 40 and provided independently.

[0070] The external system 90 may perform a function of driving and controlling the driver 40 and the electronic devices.

[0071] For example, the electronic device may be a wearable device worn on the user's body, as described above. Specifically, the wearable device may be worn on the user's wrist, knee, or elbow. The electronic device may output various images, communicate with an external server via a wireless communication network, and output various voice messages.

[0072] The external system 90 may receive various sound information and image information through the communication network, or may generate image information itself and transmit the image information to the control driver 40. In addition, the external system 90 may transmit at least one of the stretching state (e.g., whether it is stretched), the stretching degree, and the stretching coordinates determined by the stretching panel 60 to the outside through the communication network.

[0073] The external system 90 may convert image information into input image data Ri, Gi, and Bi and transmit the input image data Ri, Gi, and Bi to the control driver 40 .

[0074] The power supply unit may generate various powers and supply the generated powers to the control driver 40 , the gate driver 20 , the data driver 30 , and the touch driver 50 .

[0075] The gate driver 20 may be directly embedded in the non-display area NDA by using a gate in panel (GIP) type, or the gate driver 20 may be disposed in the display area DA where the light-emitting device ED is disposed, or the gate driver 20 may be disposed on a chip-on-film package mounted in the non-display area NDA.

[0076] The gate driver 20 may provide gate pulses GP1 to GPg to the gate lines GL1 to GLg.

[0077] When a gate pulse GP generated by the gate driver 20 is supplied to the gate of the switching transistor Tsw1 included in the pixel P, the switching transistor Tsw1 may be turned on. When the switching transistor Tsw1 is turned on, the pixel P may be supplied with a data voltage Vdata supplied through the data line DL.

[0078] When the gate-off signal generated by the gate driver 20 is supplied to the switching transistor Tsw1, the switching transistor Tsw1 may be turned off. When the switching transistor Tsw1 is turned off, the data voltage may no longer be supplied to the pixel P.

[0079] The gate signal GS supplied to the gate line GL may include a gate pulse GP and a gate-off signal.

[0080] In order to provide gate pulses GP1 to GPg to the gate lines GL1 to GLg, as shown in FIG. Figure 4 As shown, the gate driver 20 may include stages ST1 to STg connected to the gate lines GL1 to GLg.

[0081] Each of the stages ST1 to STg may be connected to one gate line GL, but may also be connected to at least two gate lines GL.

[0082] To generate the gate pulses GP1 to GPg, a gate start signal VST and at least one gate clock GCLK generated by the control signal generator 420 may be transmitted to the gate driver 20. For example, the gate start signal VST and at least one gate clock GCLK may be included in the gate control signal GCS.

[0083] One of the stages ST1 to STg may be driven by the gate start signal VST to output a gate pulse GP to the gate line GL. The gate pulse GP may be generated by the gate clock GCLK.

[0084] At least one of the signals output from the stage ST outputting the gate pulse may be provided to another stage ST to drive the other stage ST. Therefore, the gate pulse may be output in the other stage ST.

[0085] For example, the stages ST may be driven sequentially to sequentially supply the gate pulses GP to the gate lines GL.

[0086] The data driver 30 may provide a data voltage Vdata to the data lines DL1 to DLd.

[0087] For this reason, Figure 5 As shown, the data driver 30 may include: a shift register 310, which outputs a sampling signal; a latch 320, which latches the image data Data received from the control driver 40; a digital-to-analog converter 330, which converts the image data Data transmitted from the latch 320 into a data voltage Vdata and outputs the data voltage Vdata; and an output buffer 340, which outputs the data voltage transmitted from the digital-to-analog converter 330 to the data line DL based on the source output enable signal SOE.

[0088] The shift register 310 may output a sampling signal by using the data control signal DCS received from the control signal generator 420. For example, the data control signal DCS transmitted to the shift register 310 may include a source start pulse SSP and a source shift clock signal SSC.

[0089] The latch 320 may latch the image data Data sequentially received from the control driver 40 and then simultaneously output the image data Data to the digital-to-analog converter 330 based on the sampling signal.

[0090] The digital-to-analog converter 330 may convert the image data Data transferred from the latch 320 into a data voltage Vdata and output the data voltage Vdata.

[0091] The output buffer 340 may simultaneously output the data voltage Vdata transmitted from the digital-to-analog converter 330 to the data lines DL1 to DLd of the display panel 200 based on the source output enable signal SOE transmitted from the control signal generator 420 .

[0092] To this end, the output buffer 340 may include a buffer 341 storing the data voltage Vdata transferred from the D / A converter 330 and a switch 342 outputting the data voltage Vdata stored in the buffer 341 to the data line DL based on a source output enable signal SOE.

[0093] For example, when the switch 342 is turned on based on the source output enable signal SOE simultaneously supplied to the switch 342 , the data voltage Vdata stored in the buffer 341 may be supplied to the data lines DL1 to DLd through the switch 342 .

[0094] The data voltage Vdata supplied to the data lines DL1 to DLd may be supplied to the pixels P connected to the gate line GL supplied with the gate pulse GP.

[0095] The touch driver 50 may provide a touch driving signal to the touch panel 300 and may determine whether a touch exists by using a touch sensing signal received from the touch panel 300 .

[0096] Finally, the stretch driver 60 may provide a stretch driving signal to the stretch panel 100 and may determine whether there is stretch by using the stretch sensing signal received from the stretch panel 100 .

[0097] Figure 6 is an exemplary diagram schematically illustrating a structure of a light-emitting display panel applied to an apparatus for sensing stretching according to an embodiment of the present disclosure.

[0098] First, the stretch panel 100 may include a stretch support substrate 101, a stretch substrate 103 disposed on the stretch support substrate 101, an adhesive 102 for bonding the stretch support substrate 101 and the stretch substrate 103, a metal electrode 104 disposed on the stretch substrate 103, and at least one stretch passivation layer 105 covering the metal electrode 104.

[0099] The tensile support substrate 101 may be formed of, for example, polydimethylsiloxane (PDMS). That is, the tensile support substrate 101 may be formed of a material such as silicon. Therefore, the tensile support substrate 101 is a stretchable substrate.

[0100] The tensile substrate 103 may be formed of a material such as polyimide.

[0101] The metal electrode 104 may be provided on the stretched substrate 103. The metal electrode 104 may be formed of copper, and may also be formed of various metals used to manufacture a light-emitting display device. The metal electrode 104 forms a stretched electrode.

[0102] The metal electrode 104 may be covered by a tensile passivation layer 105 .

[0103] The tensile passivation layer 105 may be formed of, for example, silicon oxide (SiOx) or silicon nitride (SiNx), metal oxide, or metal nitride, or may be formed of various inorganic materials used to manufacture a light-emitting display device.

[0104] In addition to the tensile passivation layer 105 , the tensile panel 100 may further include at least one inorganic material layer.

[0105] At least one inorganic material layer may be, for example, a bridge insulating layer 107 to isolate the bridge 106 from the metal electrode 104. The bridge 106 may be formed of the same metal as the metal electrode 104, and may also be formed of various metals used to manufacture light-emitting display devices.

[0106] To allow the stretch panel 100 to be stretched, as Figure 6 As shown, the tensile substrate 103 and the tensile passivation layer 105 are not disposed in regions other than the region where the metal electrodes 104 and the bridges 106 are located in the tensile panel 100 , and the at least one inorganic layer disposed in the tensile panel 100 is also not disposed in this region.

[0107] In the following description, the region where the metal electrode 104 or the bridge 106 is provided is referred to as the rigid region RA. In addition, the region where the metal electrode 104, the bridge 106, the tensile substrate 103 and the tensile passivation layer 105 are not provided is referred to as the soft region SA.

[0108] To provide additional description, the tensile substrate 103 is disposed between the tensile support substrate 101 and the metal electrode 104, and includes mesh portions 103a connected like a mesh. Opening portions 103b are formed between the mesh portions 103a.

[0109] In this case, the metal electrode 104 may be provided only in the mesh portion 103 a .

[0110] That is, in the following description, the tensile substrate 103 may represent the mesh portion 103 a .

[0111] In addition, the rigid area RA may correspond to the mesh portion 103 a , and the soft area SA may correspond to the opening portion 103 b .

[0112] A brief description of the manufacturing process of the tensile panel 100 is as follows.

[0113] A material such as polyimide is deposited on a carrier substrate (eg, a glass substrate) to form a tensile substrate layer.

[0114] Metal electrodes 104 are formed on the tensile substrate layer.

[0115] The metal electrode 104 is covered by a tensile passivation layer material.

[0116] When the tensile substrate layer and the tensile passivation layer material in the area without the metal electrode 104 are removed by, for example, laser, a Figure 6The stretched substrate 103 and the stretched passivation layer 105 are shown as Figure 6 shown.

[0117] Then, the carrier substrate is removed.

[0118] The tension support substrate 101 is attached to the tension substrate 103 from which the carrier substrate is removed by using an adhesive 102 .

[0119] Thus, the tensile panel 100 can be finally manufactured.

[0120] Next, the display panel 200 may include a display support substrate 201, a display substrate 203 arranged on the display support substrate 201, a display substrate adhesive 202 bonding the display support substrate 201 and the display substrate 203, at least two display electrodes 204 arranged on different layers, and at least two display insulating layers 205 covering the at least two display electrodes 204.

[0121] The display support substrate 201 may be formed of, for example, polydimethylsiloxane (PDMS). That is, the display support substrate 201 may be formed of a material such as silicon. Therefore, the display support substrate 201 is a stretchable substrate.

[0122] The display substrate 203 may be formed of a material such as polyimide.

[0123] At least two display electrodes 204 may be provided on the display substrate 203 , forming various types of lines and electrodes, such as a gate, source and electrode, a gate line GL, a data line DL, an anode and a cathode of each of the transistors Tsw1 , Tsw2 and TDR.

[0124] Each of the at least two display electrodes 204 may be formed of at least one opaque electrode, at least one transparent electrode, or at least one opaque electrode and at least one transparent electrode.

[0125] At least two display electrodes 204 may be formed of different materials.

[0126] The display insulating layer 205 may be provided between the display electrodes 204 provided on different layers. The display insulating layer 205 may include at least one organic material layer, at least one inorganic material layer, or at least one organic material layer and at least one inorganic material layer.

[0127] The upper end of the light emitting device ED including the anode, the light emitting layer, and the cathode may be covered by an encapsulation layer. The encapsulation layer may be included in at least two display insulating layers 205.

[0128] The encapsulation layer may include at least one inorganic material layer, at least one organic material layer, or at least one inorganic material layer and at least one organic material layer.

[0129] In order to allow the display panel 200 to be stretched, the display substrate 203 and at least two display insulating layers 205 may be removed from the display panel 200 in areas other than the areas where the display electrodes 204 are located. Figure 6 shown.

[0130] In the following description, a region in which the display electrode 204 remains is referred to as a display rigid area DRA. Also, a region in which the display electrode 204 and the display substrate 203 are not provided is referred to as a display soft area DSA.

[0131] The process of manufacturing the display panel 200 will be briefly described below.

[0132] A material such as polyimide is deposited on a carrier substrate (eg, a glass substrate) to form a display substrate layer.

[0133] At least two display electrodes 204 and at least two display insulating layer materials are formed on the display substrate layer.

[0134] like Figure 2 The driving transistors Tsw1 , Tsw2 and Tdr, the gate lines GL, the data lines DL and the light emitting devices ED constituting the pixel driving circuit PDC may be formed of at least two display electrodes 204 and at least two display insulating layer materials.

[0135] When the display substrate layer and the display insulating layer material in the region where the display electrode 204 is not present are removed by, for example, laser, a layer such as Figure 6 The display substrate 203 and at least two insulating layers 205 are shown.

[0136] Then, the carrier substrate is removed.

[0137] The display support substrate 201 is attached to the display substrate 203 from which the carrier substrate is removed by using a display substrate adhesive 202 .

[0138] Thus, the display panel 200 can be finally manufactured.

[0139] The display support substrate 201 may be bonded to the tension panel 100 by using a display support substrate adhesive 201 a .

[0140] Therefore, the display panel 200 and the tension panel 100 may be finally attached to each other.

[0141] Before the display panel 200 and the stretch panel 100 are bonded, another stretch support substrate may be further attached to the upper end of the stretch panel 100. In this case, the another stretch support substrate provided on the upper end of the stretch panel 100 and the display support substrate 201 of the display panel 200 may be bonded by the display support substrate adhesive 201a.

[0142] Another tensile support substrate disposed at the upper end of the tensile panel 100 may be formed of the same material as the tensile support substrate 101 disposed at the lower end of the tensile panel 100 .

[0143] Finally, as described above, the touch panel 300 may be formed using a mutual method or a self-capture method. Hereinafter, for convenience of description, the touch panel 300 using the mutual method is described as an example of a touch panel applied to the apparatus for sensing stretch according to an embodiment of the present disclosure.

[0144] The touch panel 300 may include a touch supporting substrate 301, a touch substrate 303 arranged on the touch supporting substrate 301, a touch substrate adhesive 302 for bonding the touch supporting substrate 301 and the touch substrate 303, a touch bridge 304 arranged on the touch substrate 303, a touch bridge insulating layer 305 covering the touch bridge 304, a touch electrode layer 306 arranged on the touch bridge insulating layer 305, and a touch passivation layer 307 covering the touch electrode layer 306.

[0145] The touch support substrate 301 may be formed of, for example, polydimethylsiloxane (PDMS). That is, the touch support substrate 301 may be formed of a material such as silicon. Therefore, the touch support substrate 301 is a stretchable substrate.

[0146] The touch substrate 303 may be formed of a material such as polyimide.

[0147] The touch bridge 304 may be disposed on the touch substrate 303 .

[0148] The touch bridge 304 may be formed of at least one opaque electrode, at least one transparent electrode, or at least one opaque electrode and at least one transparent electrode.

[0149] The touch bridge 304 may be covered by a touch bridge insulating layer 305. The touch bridge insulating layer 305 may include at least one organic layer, at least one inorganic layer, or at least one organic layer and at least one inorganic layer.

[0150] The touch electrode layer 306 forming the touch driving electrodes or the touch receiving electrodes is disposed on the touch bridge insulating layer 305 .

[0151] Two touch electrode layers 306 forming touch driving electrodes or two touch electrode layers 306 forming touch receiving electrodes may be connected to the touch bridge 304 through contact holes provided in the touch bridge insulating layer 305 .

[0152] That is, in the area where the touch driving electrodes and the touch receiving electrodes intersect, two touch electrode layers 306 forming the touch driving electrodes or two touch electrode layers 306 forming the touch receiving electrodes may be connected by the touch bridge 304 .

[0153] The touch electrode layer 306 may be covered by a touch passivation layer 307. The touch passivation layer 307 may include at least one organic layer, at least one inorganic layer, or at least one organic layer and at least one inorganic layer.

[0154] In the following description, the area where the touch bridge 304 or the touch electrode layer 304 remains is referred to as a touch rigid area TRA, and the area where the touch bridge 304, the touch electrode layer 304, and the touch substrate 303 are not provided is referred to as a touch soft area TSA.

[0155] The process of manufacturing the touch panel 300 will be briefly described below.

[0156] A material such as polyimide is deposited on a carrier substrate (eg, a glass substrate) to form a touch substrate layer.

[0157] At least one touch bridge 304 may be disposed on the touch substrate layer and may be covered by a touch bridge insulating material. At least one touch electrode layer 306 may be disposed on the touch bridge insulating material and may be covered by a touch passivation material.

[0158] When the touch substrate layer and the touch insulating layer material in the region without the touch bridge 304 and the touch electrode layer 306 are removed by, for example, laser, a Figure 6 The touch substrate 303 is shown.

[0159] Then, the carrier substrate is removed.

[0160] The touch support substrate 301 is attached to the touch substrate 303 from which the carrier substrate is removed by using a touch substrate adhesive 302 .

[0161] Another touch support substrate 401 may be attached to the upper end of the touch passivation layer 307 by using a touch passivation layer adhesive 401a. The other touch support substrate 401 may be formed of the same material as the touch support substrate 301 disposed at the lower end of the touch panel 300.

[0162] In this way, the touch panel 300 can be finally manufactured.

[0163] The touch support substrate 301 may be bonded to the display panel 200 by using a touch support substrate adhesive 301 a .

[0164] Thus, the touch panel 300 and the display panel 200 can be finally attached together.

[0165] Before bonding the touch panel 300 to the display panel 200, another display support substrate may be further attached to the upper end of the display panel 200. In this case, the other display support substrate disposed on the upper end of the display panel 200 and the touch support substrate 301 of the touch panel 300 may be bonded by the touch support substrate adhesive 301a.

[0166] Another display support substrate disposed at the upper end of the display panel 200 may be formed of the same material as the display support substrate 201 disposed at the lower end of the display panel 200 .

[0167] The stretch sensing apparatus according to an embodiment of the present disclosure may include only the stretch panel 100 , or may include the stretch panel 100 and the display panel 200 , or may include the stretch panel 100 , the display panel 200 , and the touch panel 300 .

[0168] When the apparatus for sensing stretch according to an embodiment of the present disclosure includes only the stretch panel 100 , another stretch supporting substrate may be attached to the upper surface of the stretch panel 100 .

[0169] When the apparatus sensing stretch according to an embodiment of the present disclosure includes the stretch panel 100 and the display panel 200 disposed on the stretch panel 100 , another display support substrate may be attached to the upper surface of the display panel 200 .

[0170] Figure 7 FIG. 1 is an exemplary diagram schematically illustrating a structure of a stretch panel applied to an apparatus for sensing stretch according to an embodiment of the present disclosure.

[0171] like Figure 7 As shown, the stretching panel 100 may include a stretching area 109a and a stretching line area 109b, in which a driving electrode TX, a single receiving electrode RX_X and a cross receiving electrode RX_Y are provided, and in the stretching line area 109b, the driving electrode line TX_L is connected to the driving electrode TX, the single receiving electrode line RX_XL is connected to the single receiving electrode RX_X, and the cross receiving electrode line RX_YL is connected to the cross receiving electrode RX_Y.

[0172] The stretch area 109a may correspond to the display area DA, but does not necessarily coincide with the display area DA.

[0173] As described above, the stretch panel 100 may include three types of stretch electrodes to sense whether there is stretch.

[0174] The three types of stretching electrodes include a driving electrode TX, a single receiving electrode RX_X, and a cross receiving electrode RX_Y.

[0175] Each of the driving electrodes TX extends in a first direction (eg, Y-axis direction Y) of the tensile panel 100 and may intersect with the single receiving electrode RX_X and the cross receiving electrode RX_Y, as shown in FIG. Figure 7 In the following description, the first direction may be represented by the reference sign Y.

[0176] Each of the single receiving electrodes RX_X extends in a second direction (eg, X-axis direction X) different from the first direction Y, as shown in FIG. Figure 7 In the following description, the second direction may be represented by a reference sign X.

[0177] Each of the cross receiving electrodes RX_Y extends in the second direction X, as shown in FIG. Figure 7 As shown in .

[0178] The driving electrode line TX_L, the single receiving electrode line RX_XL, and the cross receiving electrode line RX_YL are connected to the stretching driver 60 .

[0179] The stretch driver 60 may sequentially provide a stretch driving signal to the driving electrode TX. When the stretch driving signal is provided from the stretch driver 60 to the driving electrode TX, if the stretch panel 100 is stretched, the capacitance between the driving electrode TX and the single receiving electrode RX_X may be changed, or the capacitance between the driving electrode TX and the cross receiving electrode RX_Y may be changed.

[0180] For example, when the panel 100 is stretched in the first direction Y (i.e., Figure 7 When the stretch panel 100 is stretched (in the vertical direction shown), the capacitance between the driving electrode TX and the cross receiving electrode RX_Y can be changed, and therefore, at least one of the current, voltage and capacitance of the stretch sensing signal received by the cross receiving electrode RX_Y can be changed.

[0181] The stretch driver 60 may analyze a change in at least one of current, voltage, and capacitance to determine at least one of stretching of the stretch panel 100 in the vertical direction, a stretching degree of the stretch panel 100 in the vertical direction, and a stretching coordinate where the stretching occurs.

[0182] However, after the stretch driver 60 generates stretch information corresponding to the amount of change in at least one of current, voltage, and capacitance, the stretch information may be transmitted to the control driver 40 or a separate determination unit. In this case, the control driver 40 or the separate determination unit may determine at least one of the stretch in the vertical direction of the stretch panel 100, the degree of stretch in the vertical direction of the stretch panel 100, and the stretch coordinates at which the stretch occurs by using the stretch information.

[0183] In addition, when the stretch panel 100 is stretched in the second direction X (ie, Figure 7 When the stretch panel 100 is stretched in the left-right direction (left-right direction) shown in the figure, the capacitance between the driving electrode TX and the single receiving electrode RX_X can be changed, and therefore, at least one of the current and voltage of the stretch sensing signal received by the single receiving electrode RX_X can be changed.

[0184] The stretch driver 60 may analyze a change in at least one of current, voltage, and capacitance to determine at least one of left-right stretching of the stretch panel 100 , a stretching degree in the left-right direction, and a stretching coordinate where the stretching occurs.

[0185] However, after the stretch driver 60 generates stretch information corresponding to the amount of change in at least one of current, voltage, and capacitance, the stretch information may be transmitted to the control driver 40 or a separate determination unit. In this case, the control driver 40 or the separate determination unit may determine at least one of the stretch in the left-right direction of the stretch panel 100, the degree of stretch in the left-right direction of the stretch panel 100, and the stretch coordinates where the stretch occurs by using the stretch information.

[0186] That is, the capacitance change between the driving electrode TX and the cross receiving electrode RX_Y can be used to determine whether the stretch panel 100 is stretched in the first direction Y (for example, the vertical direction) of the stretch panel 100, and the capacitance change between the driving electrode TX and the single receiving electrode RX_X can be used to determine whether the stretch panel 100 is stretched in the second direction X (for example, the left and right direction) of the stretch panel 100.

[0187] Figure 8 is an exemplary diagram illustrating three driving electrodes, three single receiving electrodes, and three crossed receiving electrodes provided in a stretch panel of an apparatus for sensing stretch according to an embodiment of the present disclosure.

[0188] The stretch panel 100 may be provided with various numbers of driving electrodes TX, single receiving electrodes RX_X, and cross receiving electrodes RX_Y according to the size of the stretch panel 100. Among the at least three driving electrodes TX, at least three single receiving electrodes RX_X, and at least three cross receiving electrodes RX_Y provided in the stretch panel 100, Figure 8 Three driving electrodes TX, three single receiving electrodes RX_X and three crossed receiving electrodes RX_Y are shown in FIG.

[0189] As reference Figure 6 and 7 As described, the stretch panel 100 applied to the stretch sensing device according to the embodiment of the present disclosure includes a stretch support substrate 101 to be stretched and a driving electrode TX, a single receiving electrode RX_X and a cross receiving electrode RX_Y provided on the stretch support substrate 101.

[0190] The tension substrate 103 is disposed between the driving electrode TX, the single receiving electrode RX_X, the cross receiving electrode RX_Y, and the tension support substrate 101 .

[0191] The stretched substrate 103 includes a patterned mesh portion and openings, which are the empty spaces between the mesh portions. Therefore, the stretched substrate 103 can be stretched along with the stretched support substrate 101, and the drive electrode TX, single receive electrode RX_X, and cross receive electrode RX_Y disposed on the stretched substrate 103 can also be stretched.

[0192] like Figure 8 As shown, each of the driving electrodes TX includes a first direction driving electrode 111 extending in a first direction Y of the tensile support substrate 101 and a second direction driving electrode 112 connected to the first direction driving electrode 111 and extending in a second direction X different from the first direction Y.

[0193] For example, each of the driving electrodes TX includes one first direction driving electrode 111 and at least two second direction driving electrodes 112 .

[0194] In this case, each of the driving electrodes TX is connected to a driving electrode line TXL, such as Figure 7 As shown, and can be connected to the stretching driver 60 through the driving electrode line TXL.

[0195] In particular, the first direction driving electrode 111 of each of the driving electrodes TX may be connected to the stretching driver 60 through a driving electrode line TXL.

[0196] Each of the single receiving electrodes RX_X may extend in the second direction X.

[0197] Specifically, each of the single receiving electrodes RX_X may be continuously disposed in the second direction X of the tension panel 100 .

[0198] In this case, each of the single receiving electrodes RX_X is connected to a single receiving electrode line RX_XL, as shown in FIG. Figure 7, and can be connected to the stretching driver 60 via a single receiving electrode line RX_XL.

[0199] Each of the cross reception electrodes RX_Y may extend in the first direction Y and the second direction X.

[0200] Each of the cross receiving electrodes RX_Y includes a second direction cross receiving electrode 132 extending in the second direction X and a first direction cross receiving electrode 131 connected to the second direction cross receiving electrode 132 and extending in the first direction Y. Figure 8 shown.

[0201] For example, each of the cross-receiving electrodes RX_Y includes one second-direction cross-receiving electrode 132 and at least two first-direction cross-receiving electrodes 131 .

[0202] In this case, if Figure 7 As shown, each of the cross-receiving electrodes RX_Y is connected to a cross-receiving electrode line RX_YL and may be connected to the stretching driver 60 through the cross-receiving electrode line RX_YL.

[0203] Specifically, the second direction cross-reception electrode 132 of each of the cross-reception electrodes RX_Y may be connected to the stretching driver 60 through a cross-reception electrode line RX_YL.

[0204] Hereinafter, the structure of each of the driving electrode TX, the single reception electrode RX_X, and the cross reception electrode RX_Y will be described in detail.

[0205] Figure 9 It shows Figure 8 An example diagram of the structure of three driving electrodes is shown.

[0206] As described above, each of the driving electrodes TX includes the first direction driving electrode 111 extending in the first direction Y of the tension support substrate 101 and the second direction driving electrode 112 connected to the first direction driving electrode 111 and extending in the second direction Y different from the first direction Y.

[0207] For example, each of the driving electrodes TX includes one first direction driving electrode 111 and at least two second direction driving electrodes 112 .

[0208] First, each of the second direction driving electrode 112 and the first direction driving electrode 111 constituting the driving electrode TX has a cross shape.

[0209] For example, Figure 9As shown, the first direction driving electrodes 111 and the second direction driving electrodes 112 intersect with each other, and thus, the first direction driving electrodes 111 and the second direction driving electrodes 112 have a cross shape.

[0210] For example, the first direction driving electrode 111 is Figure 7 The illustrated stretching region 109 a extends from an upper end to a lower end and may be connected to a stretching actuator 60 .

[0211] The second direction driving electrode 112 may be, for example, Figure 7 A portion of the stretched region 109a is shown extending along the second direction X.

[0212] In this case, the second direction driving electrodes 112 adjacent to each other along the second direction X are spaced apart from each other.

[0213] That is, at least two second direction driving electrodes 112 may be disposed along the second direction X of the tensile panel 100 , may be spaced apart from each other, and may be arranged in a line.

[0214] Next, the first direction driving electrode 111 includes two first direction driving electrode branches 111 a adjacent to each other and a driving electrode bridge 111 b connecting the two first direction driving electrode branches 111 a .

[0215] For example, two first direction driving electrode branches 111 a are connected to the driving electrode bridge 111 b , and the two first direction driving electrode branches 111 a extend in the first direction Y.

[0216] The two first direction driving electrode branches 111 a may be formed on the same layer as the driving electrode bridge 111 b , may be disposed at both ends of the driving electrode bridge 111 b , and may be connected to the driving electrode bridge 111 b .

[0217] That is, the two first direction driving electrode branches 111 a may be electrically connected to each other through the driving electrode bridge 111 b .

[0218] In this case, the second direction driving electrode 112 may be connected to the driving electrode bridge 111 b through a contact hole formed in a bridge insulating layer covering the driving electrode bridge 111 b.

[0219] For example, along Figure 9 The cross-sectional surface taken along the line CC' shown in FIG can be Figure 6 The cross-sectional surface CC' is shown in FIG.

[0220] That is, as referenced Figure 6As described above, the tensile support substrate 101 may be connected to the tensile substrate 103 via the adhesive 102 .

[0221] The tensile substrate 103 may include mesh portions 103 a connected like a mesh, and opening portions 103 b are formed between the mesh portions 103 a.

[0222] In this case, Figure 6 In the cross section CC′, the bridge 106 may be the driving electrode bridge 111 b , and the metal electrode 104 may be the second direction driving electrode 112 .

[0223] That is, Figure 6 As shown, the driving electrode bridge 111b can be provided on the mesh portion 103a, the driving electrode bridge 111b can be covered by the bridging insulating layer 107, and the second direction driving electrode 112 can be connected to the driving electrode bridge 111b through a contact hole formed in the bridging insulating layer 107 covering the driving electrode bridge 111b.

[0224] To provide additional description, the first direction driving electrode branches 111 a and the second direction driving electrodes 112 are electrically connected through the driving electrode bridges 111 b .

[0225] Therefore, the driving electrode TX including the first direction driving electrode branches 111 a , the driving electrode bridges 111 b , and the second direction driving electrodes 112 may function as one electrode.

[0226] Next, as described above, the first direction driving electrode 111 includes two first direction driving electrode branches 111 a adjacent to each other and a driving electrode bridge 111 b connecting the two first direction driving electrode branches 111 a .

[0227] In this case, if Figure 9 As shown, each of the two first direction driving electrode branches 111 a may have a circular shape with a peak portion 111 c and a valley portion 111 d .

[0228] For example, in Figure 9 In the illustrated first direction driving electrode branch 111 a , the peak portion 111 c may indicate a portion protruding in the left direction, and the valley portion 111 d may indicate a portion protruding in the right direction.

[0229] That is, the first direction driving electrode branch 111 a may include at least one peak portion 111 c protruding in the left direction and at least one valley portion 111 d protruding in the right direction, and thus may have a circular shape.

[0230] Because the first direction driving electrode branches 111 a have a circular shape having the peaks 111 c and the valleys 111 d disposed along the first direction Y, the first direction driving electrode branches 111 a may be stretched along the first direction Y.

[0231] In this case, if Figure 9 As shown, the second direction driving electrode bar 111 e protruding in the second direction X is disposed in the valley 111 d provided in the first direction driving electrode branch 111 a .

[0232] The second direction driving electrode rod 111e extends in a direction opposite to the direction in which the peak portion 111c is located. That is, the second direction driving electrode rod 111e may protrude from the valley portion 111d in a right direction of the valley portion 111d, as shown in FIG. Figure 9 shown.

[0233] Finally, each of the second direction driving electrodes 112 may be, for example, Figure 7 The stretch region 109a is shown extending from the left side to the right side.

[0234] Each of the second direction driving electrodes 112 may have a circular shape having a peak portion 112c and a valley portion 112d, as shown in FIG. Figure 9 shown.

[0235] For example, in Figure 9 In the second direction driving electrode 112 shown, the peak portion 112 c may indicate a portion protruding in an upward direction, and the valley portion 112 d may indicate a portion protruding in a downward direction.

[0236] That is, the second direction driving electrode 112 may include at least one peak portion 112 c protruding in an upper direction and at least one valley portion 112 d protruding in a lower direction, and thus may have a circular shape.

[0237] Since the second direction driving electrode 112 has a circular shape having the peak portion 112 c and the valley portion 112 d disposed along the second direction X as described above, the second direction driving electrode 112 may be stretched along the second direction X.

[0238] In this case, if Figure 9 As shown, the first direction driving electrode bar 112 e protruding in the first direction Y is disposed in the valley 112 d provided in the second direction driving electrode 112 .

[0239] The first direction driving electrode rod 112e extends in a direction opposite to the direction in which the peak portion 112c is located. That is, the first direction driving electrode rod 112e may protrude upward from the valley portion 112d below the valley portion 112d, as shown in FIG. Figure 9 shown.

[0240] Figure 10 It shows Figure 8 An example diagram of the structure of three single receiving electrodes is shown in FIG. Figure 11 It shows Figure 8 Specifically, Figure 11 (a) shows the state where the second direction driving electrode 112 and the single receiving electrode RX_X are not stretched, and Figure 11 (b) shows a state where the second direction driving electrode 112 and the single receiving electrode RX_X are stretched.

[0241] Each of the single receiving electrodes RX_X may extend in the second direction X of the tensile support substrate 101 , as described above.

[0242] Each of the single receiving electrodes RX_X Figure 7 The stretching region 109 a shown in FIG. 1 extends from a left end to a right end and is connected to the stretching driver 60 .

[0243] First, each of the single receiving electrodes RX_X may have a circular shape having a peak portion 121c and a valley portion 121d, as shown in FIG. Figure 10 As shown in .

[0244] For example, in Figure 10 In the single receiving electrode RX_X shown in FIG, the peak portion 121 c may denote a portion protruding in an upper direction, and the valley portion 121 d may denote a portion protruding in a lower direction.

[0245] That is, the single receiving electrode RX_X may include at least one peak portion 121 c protruding in an upper direction and at least one valley portion 121 d protruding in a lower direction, and thus may have a circular shape.

[0246] Because the single receiving electrode RX_X has a circular shape having the peak portion 121 c and the valley portion 121 d disposed along the second direction X, the single receiving electrode RX_X may be stretched along the second direction X.

[0247] In this case, if Figure 10 As shown, the first direction single receiving electrode bar 121e protruding in the first direction Y is provided in the peak portion 121c provided in the single receiving electrode RX_X.

[0248] The first direction single receiving electrode bar 121e extends in a direction opposite to the direction in which the valley portion 121d is located. That is, the first direction single receiving electrode bar 121e may protrude from the peak portion 121c upwardly, as shown in FIG. Figure 10 As shown in .

[0249] Next, among the second direction driving electrodes 112 provided among the driving electrodes TX provided along the second direction X, the second direction driving electrodes 112 adjacent along the second direction X may be spaced apart from each other by a certain interval and may be provided in a row.

[0250] For example, Figure 8 and 9 As shown, the driving electrodes TX may be disposed along the second direction X. In this case, the driving electrodes TX spaced apart along the second direction X are independently driven.

[0251] Therefore, among the second direction driving electrodes 112 arranged among the driving electrodes TX arranged along the second direction X, the second direction driving electrodes 112 adjacent along the second direction X are spaced at regular intervals.

[0252] In addition, among the second direction driving electrodes 112 provided among the driving electrodes TX arranged along the second direction X, the second direction driving electrodes 112 adjacent along the second direction X may be arranged in a row.

[0253] Each of the single receiving electrodes RX_X extends from the left end to the right end of the stretching region 109 a .

[0254] In this case, the single receiving electrode RX_X may be disposed in parallel to the second direction driving electrodes 112 disposed in a row.

[0255] For example, the second direction driving electrodes 112 arranged in a row may be disposed on the same layer as the single receiving electrode RX_X, and may be disposed in parallel with the single receiving electrode RX_X.

[0256] To provide additional description, a single receiving electrode RX_X may be disposed in parallel with at least two second direction driving electrodes 112 .

[0257] Next, as described above, the single receiving electrode RX_X may have a circular shape having a peak portion 121 c and a valley portion 121 d , and the peak portion 121 c may be provided with a first direction single receiving electrode bar 121 e protruding in the first direction Y.

[0258] In addition, each of the second direction driving electrodes 112 disposed parallel to the single receiving electrode RX_X may have a circular shape having a peak 112c and a valley 112d, and the valley 112d may be provided with a first direction driving electrode bar 112e protruding in the first direction Y.

[0259] In this case, the first direction single-receiving electrode bar 121e and the first direction driving electrode bar 112e may be disposed adjacent to each other along the second direction X. Figure 8 and 11As shown in the first area AR1.

[0260] That is, the first direction single-receiving electrode bar 121e and the first direction driving electrode bar 112e are adjacent to and spaced apart from each other.

[0261] For example, along Figure 8 The cross-sectional surface taken along the line AA' shown in FIG. 1 may be Figure 6 The cross-sectional surface AA' is shown in FIG.

[0262] That is, as referenced Figure 6 As described above, the tensile support substrate 101 may be connected to the tensile substrate 103 via the adhesive 102 .

[0263] The tensile substrate 103 may include mesh portions 103 a connected like a mesh, and opening portions 103 b are formed between the mesh portions 103 a.

[0264] In this case, Figure 6 In the cross-sectional surface AA′, the two metal electrodes 104 may be a first direction single receiving electrode rod 121 e and a first direction driving electrode rod 112 e.

[0265] That is, each of the first direction single receiving electrode bar 121e and the first direction driving electrode bar 112e may be disposed on the mesh portion 103a and may be covered by the tensile passivation layer 105, as shown in FIG. Figure 6 shown.

[0266] Finally, the first direction single receiving electrode bar 121e of the single receiving electrode RX_X can be set in the peak 121c of the single receiving electrode RX_X and can protrude toward the peak 112c of the second direction driving electrode 112 adjacent to the first direction single receiving electrode bar 121e, as shown in FIG. Figure 11 As shown in .

[0267] In this case, the first direction driving electrode bar 112e disposed in the valley 112d of the second direction driving electrode 112 adjacent to the first direction single receiving electrode bar 121e may protrude toward the valley 121d of the single receiving electrode RX_X.

[0268] That is, the peaks 121c and 112c of the receiving electrode RX_X and the second direction driving electrode 112 may be arranged in vertical rows along the first direction Y, and the valleys 121d and 112d of the receiving electrode RX_X and the second direction driving electrode 112 may be arranged in vertical rows along the first direction Y.

[0269] Therefore, the first direction single-receiving electrode bar 121e and the first direction driving electrode bar 112e may be disposed adjacent to each other along the second direction X.

[0270] Will refer to Figure 11 A method of determining whether the stretch panel 100 is stretched in the second direction X is described.

[0271] For example, as described above, the stretching driver 60 sequentially supplies the stretching driving signal to the driving electrode TX.

[0272] In this case, if there is no stretching, then Figure 11 As shown in (a), the distance F between the first direction driving electrode rod 112e and the single receiving electrode rod 121e is kept constant.

[0273] However, if Figure 11 As shown in (a), when the stretch panel 100 is stretched in the second direction X, the second direction driving electrode 112 and the single receiving electrode RX_X may be stretched by K.

[0274] In this case, the distance F between the first direction driving electrode bar 112e and the first direction single-receiving electrode bar 121e is also increased.

[0275] That is, after the second direction driving electrode 112 and the single receiving electrode RX_X are stretched K in the second direction X, the distance F1 between the first direction driving electrode rod 112e and the first direction single receiving electrode rod 121e is greater than the distance F between the first direction driving electrode rod 112e and the first direction single receiving electrode rod 121e before the second direction driving electrode 112 and the single receiving electrode RX_X are stretched in the second direction X.

[0276] The capacitance formed between the first direction driving electrode bar 112e and the first direction only receiving electrode bar 121e varies based on the distance between the first direction driving electrode bar 112e and the first direction only receiving electrode bar 121e.

[0277] Therefore, by analyzing Figure 11 The capacitance between the first direction driving electrode bar 112e and the first direction single receiving electrode bar 121e shown in (a) and Figure 11 The capacitance between the first-direction driving electrode rod 112e and the first-direction single-receiving electrode rod 121e shown in (b) can determine whether they are stretched in the second direction X.

[0278] For example, when the capacitance increases or decreases, it may be determined that the stretch panel 100 is stretched in the second direction X.

[0279] In addition, the degree of stretching in the second direction X may be determined by analyzing the amount of change in capacitance between the first direction driving electrode bar 112e and the first direction only receiving electrode bar 121e.

[0280] For example, as the amount of change in capacitance increases, it may be determined that the stretch panel 100 is further stretched in the second direction X.

[0281] Furthermore, the coordinates of the region stretched in the second direction X may be determined using the coordinates of the second direction driving electrode 112 supplied with the stretch driving signal and the coordinates of the single receiving electrode RX_X sensing the capacitance change.

[0282] Figure 12 It shows Figure 8 An example diagram of the structure of three crossed receiving electrodes is shown in FIG. Figure 13 (a) and (b) show Figure 8 An example diagram of the second area shown. Specifically, Figure 13 (a) shows the state where the first-direction driving electrode branch 111a and the first-direction cross-receiving electrode branch 131a are not stretched. Figure 13 (b) shows a state where the first-direction driving electrode branch 111 a and the first-direction cross-receiving electrode branch 131 a are stretched.

[0283] First, each of the cross receiving electrodes RX_Y may extend in the first direction Y and the second direction X of the tensile support substrate 101 , as described above.

[0284] For example, each of the cross receiving electrodes RX_Y may include a second direction cross receiving electrode 132 extending in the second direction X and a first direction cross receiving electrode 131 connected to the second direction cross receiving electrode 132 and extending in the first direction Y. Figure 7 、 8 and 12.

[0285] The second direction cross receiving electrode 132 may extend from the left end to the right end of the stretch panel 100 and may be connected to the stretch driver 60 .

[0286] At least two first-direction cross-receiving electrodes 131 may be connected to the second-direction cross-receiving electrode 132 .

[0287] Each of the first-direction cross-reception electrodes 131 is connected to the second-direction cross-reception electrode 132 .

[0288] Next, each of the first direction cross-reception electrode 131 and the second direction cross-reception electrode 132 has a cross shape.

[0289] For example, Figure 12 As shown, the first-direction cross-receiving electrode 131 and the second-direction cross-receiving electrode 132 intersect each other, and thus, the first-direction cross-receiving electrode 131 and the second-direction cross-receiving electrode 132 have a cross shape.

[0290] For example, the second direction crosses the receiving electrode 132 from Figure 7 The stretching region 109 a is shown extending from a left end to a right end and connected to a stretching actuator 60 .

[0291] For example, the first direction crosses the receiving electrode 131. Figure 7 A portion of the stretched region 109a is shown extending along the first direction Y.

[0292] In this case, the first-direction cross-receiving electrodes 131 adjacent to each other along the first direction Y are spaced apart from each other.

[0293] That is, at least two first direction intersecting receiving electrodes 131 may be disposed along the first direction Y of the tensile panel 100 , may be spaced apart from each other, and may be arranged in vertical rows.

[0294] Next, each of the first-direction cross-receiving electrodes 131 includes two first-direction cross-receiving electrode branches 131 a adjacent to each other and a cross-receiving electrode bridge 131 b connecting the two first-direction cross-receiving electrode branches 131 a .

[0295] For example, two first-direction cross-receiving electrode branches 131 a are connected to the cross-receiving electrode bridge 131 b , and the two first-direction cross-receiving electrode branches 131 a extend in the first direction Y.

[0296] The two first-direction crossing-receiving electrode branches 131 a may be formed on the same layer as the crossing-receiving electrode bridge 131 b , may be disposed at both ends of the crossing-receiving electrode bridge 131 b , and may be connected to the crossing-receiving electrode bridge 131 b .

[0297] For example, along Figure 12 The cross-sectional surface taken along the line BB' shown in FIG can be Figure 6 The cross-sectional surface BB' is shown in FIG.

[0298] In this case, Figure 6 In the cross-sectional surface BB′, the bridge member 106 may be a cross-receiving electrode bridge member 131 b , and the metal electrode 104 may be a first-direction cross-receiving electrode branch 131 a .

[0299] That is, Figure 6 and 12As shown, the cross-receiving electrode bridge 131b can be provided on the upper surface of the mesh portion 103a, the cross-receiving electrode bridge 131b can be covered by the bridging insulating layer 107, and the first-direction cross-receiving electrode branches 131a can be connected to the cross-receiving electrode bridge 131b at both ends of the cross-receiving electrode bridge 131b.

[0300] To provide additional description, the first-direction cross-receiving electrode branches 131 a are electrically connected by the cross-receiving electrode bridge 131 b .

[0301] In this case, Figure 6 In the cross-sectional surface BB', another metal electrode 104 disposed between two metal electrodes 104 (eg, two first direction cross receiving electrode branches 131a) may be a single receiving electrode RX_X. Figure 8 and 12 That is, the single receiving electrode RX_X may overlap with the cross-receiving electrode bridge 131 b with the bridging insulating layer 107 interposed therebetween and thus not be connected to the cross-receiving electrode bridge 131 b.

[0302] In this case, the second direction cross-reception electrode 132 may be connected to the cross-reception electrode bridge 131b through a contact hole formed in a bridge insulating layer covering the cross-reception electrode bridge 131b, or as shown in FIG. Figure 6 and 12 As shown, the first direction cross-receiving electrode branch 131 a may be connected to the cross-receiving electrode bridge 131 b.

[0303] In addition, along Figure 12 The cross-sectional surface taken along the line CC' shown in FIG can be Figure 6 The cross-sectional surface CC' is shown in FIG.

[0304] That is, as referenced Figure 6 As described above, the tensile support substrate 101 may be connected to the tensile substrate 103 via the adhesive 102 .

[0305] The tensile substrate 103 may include mesh portions 103 a connected like a mesh, and opening portions 103 b are formed between the mesh portions 103 a.

[0306] To provide additional description, the tension substrate 103 may be disposed between the tension support substrate 101 and the driving electrode TX, the single receiving electrode RX_X, and the cross receiving electrode RX_Y.

[0307] The tensile substrate 103 includes mesh portions 103 a connected like a mesh, and opening portions 103 b may be formed between the mesh portions 103 a.

[0308] In this case, the driving electrode TX, the single reception electrode RX_X, and the cross reception electrode RX_Y may be provided only in the mesh portion 103 a .

[0309] In this case, Figure 6 In the cross-sectional surface CC′, the bridge member 106 may be the cross-receiving electrode bridge member 131 b , and the metal electrode 104 may be the second-direction cross-receiving electrode 132 .

[0310] For example, Figure 6 As shown, the cross-receiving electrode bridge 131b can be provided on the upper surface of the mesh portion 103a, the cross-receiving electrode bridge 131b can be covered by the bridging insulating layer 107, and the second direction cross-receiving electrode 132 can be connected to the cross-receiving electrode bridge 111b through a contact hole formed in the bridging insulating layer 107 covering the cross-receiving electrode bridge 131b.

[0311] To provide additional description, the second-direction cross-receiving electrode 132 and the first-direction cross-receiving electrode 131 are electrically connected by a cross-receiving electrode bridge 131 b .

[0312] Therefore, the cross-reception electrode RX_X including the first-direction cross-reception electrode branch 131 a , the cross-reception electrode bridge 131 b , and the second-direction cross-reception electrode 132 may function as one electrode.

[0313] Next, as described above, each of the first-direction cross-receiving electrodes 131 includes two first-direction cross-receiving electrode branches 131 a adjacent to each other and a cross-receiving electrode bridge 131 b connecting the two first-direction cross-receiving electrode branches 131 .

[0314] In this case, each of the two first-direction cross-receiving electrode branches 131a may have a circular shape having a peak portion 131c and a valley portion 131d, as shown in FIG. Figure 12 shown.

[0315] For example, in Figure 12 In the illustrated first-direction cross-receiving electrode branch 131 a , the peak portion 131 c may represent a portion protruding in the left direction, and the valley portion 131 d may represent a portion protruding in the right direction.

[0316] That is, the first-direction cross-receiving electrode branch 131 a may include at least one peak portion 131 c protruding in the left direction and at least one valley portion 131 d protruding in the right direction, and thus may have a circular shape.

[0317] As described above, since the first-direction cross-receiving electrode branches 131 a have a circular shape with the peaks 131 c and the valleys 131 d disposed along the first direction Y, the first-direction cross-receiving electrode branches 131 a may be stretched along the first direction Y.

[0318] In this case, if Figure 12 As shown, the second-direction cross-receiving electrode rod 131 e protruding in the second direction X is disposed in the peak portion 131 c disposed in the first-direction cross-receiving electrode branch 131 a.

[0319] The second direction cross receiving electrode bar 131e extends in a direction opposite to the direction in which the valley portion 131d is located. That is, the second direction cross receiving electrode bar 131e may protrude from the peak portion 131c in the left direction of the peak portion 131c, as shown in FIG. Figure 12 shown.

[0320] Next, the second-direction cross-receiving electrode 132 has a circular shape having a peak portion 132 c and a valley portion 132 d .

[0321] For example, in Figure 12 In the second direction of the illustrated cross-receiving electrode 132 , the peak portion 132 c may represent a portion protruding in an upward direction, and the valley portion 132 d may represent a portion protruding in a downward direction.

[0322] That is, the second-direction cross-receiving electrode 132 may include at least one peak portion 132 c protruding in an upper direction and at least one valley portion 132 d protruding in a lower direction, and thus may have a circular shape.

[0323] As described above, since the second direction cross receiving electrode 132 has a circular shape having the peak portion 132 c and the valley portion 132 d disposed along the second direction X, the second direction cross receiving electrode 132 may be stretched along the second direction X.

[0324] Next, among the second direction driving electrodes 112 provided among the driving electrodes TX provided along the second direction X, the second direction driving electrodes 112 adjacent along the second direction X may be spaced apart from each other by a certain interval and may be provided in a row.

[0325] For example, Figure 8 and 9 As shown, the driving electrodes TX may be disposed along the second direction X. In this case, the driving electrodes TX spaced apart along the second direction X are independently driven.

[0326] Therefore, among the second direction driving electrodes 112 arranged among the driving electrodes TX arranged along the second direction X, the second direction driving electrodes 112 adjacent to each other along the second direction X are spaced apart from each other by a certain interval.

[0327] In addition, among the second direction driving electrodes 112 provided among the driving electrodes TX arranged along the second direction X, the second direction driving electrodes 112 adjacent along the second direction X may be arranged in a row.

[0328] Each of the second-direction cross-receiving electrodes 132 extends from the left end to the right end of the stretching region 109 a .

[0329] In this case, the second direction cross receiving electrodes 132 are disposed in parallel with the second direction driving electrodes 112 disposed in a row.

[0330] For example, the second direction driving electrodes 112 arranged in a row may be arranged on the same layer as the second direction intersecting receiving electrodes 132 , and may be arranged in parallel with the second direction intersecting receiving electrodes 132 .

[0331] To provide additional description, one second-direction cross-receiving electrode 132 may be disposed in parallel with at least two second-direction driving electrodes 112 .

[0332] Next, among the first direction cross reception electrodes 131 provided in the cross reception electrodes RX_Y arranged along the first direction Y, the first direction cross reception electrodes 131 adjacent along the first direction may be spaced apart from each other by a certain interval and may be arranged in a vertical line.

[0333] For example, Figure 12 As shown in , the cross receiving electrodes RX_Y may be disposed along the first direction Y. In this case, the cross receiving electrodes RX_Y spaced apart along the first direction Y are independently driven.

[0334] Therefore, among the first-direction cross-reception electrodes 131 provided in the cross-reception electrodes RX_Y provided along the first direction Y, the first-direction cross-reception electrodes 131 adjacent to each other along the first direction Y are spaced apart from each other by a certain interval.

[0335] Furthermore, among the first-direction cross-reception electrodes 131 provided among the cross-reception electrodes RX_Y provided along the first direction Y, the first-direction cross-reception electrodes 131 adjacent along the first direction Y may be provided in a vertical row.

[0336] Each first direction driving electrode 111 extends from an upper end to a lower end of the stretching region 109 a .

[0337] In this case, the first direction driving electrodes 111 are arranged in parallel with the first direction crossing receiving electrodes 131 arranged in a vertical line.

[0338] For example, the first direction cross receiving electrodes 131 disposed in a vertical line may be disposed on the same layer as the first direction driving electrodes 111 and may be disposed in parallel with the first direction driving electrodes 111 .

[0339] To provide additional description, one first-direction driving electrode 111 may be disposed in parallel with at least two first-direction cross-receiving electrodes 131 .

[0340] Next, as described above, the first direction driving electrode 111 may have a circular shape having the peak portion 111 c and the valley portion 111 d , and the valley portion 111 d may be provided with the second direction driving electrode rod 111 e protruding in the second direction X.

[0341] In addition, each of the first direction cross receiving electrodes 131 disposed parallel to the first direction driving electrode 111 may have a circular shape including a peak portion 131c and a valley portion 131d, and the peak portion 131d may be provided with a second direction cross receiving electrode bar 131e protruding in the second direction X.

[0342] In this case, the second direction driving electrode bar 111e and the second direction cross receiving electrode bar 131e may be disposed adjacent to each other along the first direction Y. Figure 8 and 13 As shown in the second area AR2.

[0343] Finally, the second direction driving electrode bar 111e may be disposed in the valley 111d of the first direction driving electrode 111 and may protrude toward the valley 131d of the first direction cross receiving electrode 131 adjacent to the second direction driving electrode bar 111e, as shown in FIG. Figure 13 As shown in (a) and (b).

[0344] In particular, the second direction driving electrode bar 111 e provided in the first direction driving electrode branch 111 a may protrude toward the valley portion 131 d of the first direction cross receiving electrode branch 131 a .

[0345] In this case, the second direction cross receiving electrode bar 131e disposed on the peak portion 131c of the first direction cross receiving electrode branch 131a adjacent to the second direction driving electrode bar 111e may protrude toward the peak portion 111c of the first direction driving electrode branch 111a.

[0346] That is, the peaks 111c of the first direction driving electrode branches 111a and the peaks 131c of the first direction cross receiving electrode branches 131a can be arranged in a row along the second direction X, and the valleys 111d of the first direction driving electrode branches 111a and the valleys 131d of the first direction cross receiving electrode branches 131a can be arranged in a row along the second direction X.

[0347] Therefore, the second direction driving electrode bar 111e and the second direction crossing receiving electrode bar 131e may be disposed adjacent to each other along the first direction Y.

[0348] Will refer to Figure 12 A method of determining whether the stretch panel 100 is stretched in the first direction Y is described.

[0349] For example, as described above, the stretching driver 60 sequentially supplies the stretching driving signal to the driving electrode TX.

[0350] In this case, if there is no stretching, then Figure 13 As shown in (a), the distance M between the second direction driving electrode bar 111e and the second direction cross receiving electrode bar 131e is kept constant.

[0351] However, if Figure 13 As shown in (b), when the stretch panel 100 is stretched in the first direction Y, the first direction driving electrode branches 111a of the first direction driving electrode 111 and the first direction crossing receiving electrode branches 131a of the first direction crossing receiving electrode 131 may be stretched N.

[0352] In this case, the distance M between the second direction driving electrode bar 111e and the second direction cross-receiving electrode bar 131e also increases.

[0353] That is, after the first direction driving electrode branch 111a and the first direction cross-receiving electrode branch 131a are stretched N in the first direction Y, the distance M1 between the second direction driving electrode bar 111e and the second direction cross-receiving electrode bar 131e is greater than the distance M1 between the second direction driving electrode bar 111e and the second direction cross-receiving electrode bar 131e before the first direction driving electrode branch 111a and the first direction cross-receiving electrode branch 131a are stretched in the first direction Y.

[0354] The capacitance formed between the second direction driving electrode bar 111 e and the second direction cross-receiving electrode bar 131 e varies based on the distance between the second direction driving electrode bar 111 e and the second direction cross-receiving electrode bar 131 e.

[0355] Therefore, by analyzing Figure 13 The capacitance between the second direction driving electrode bar 111e and the second direction cross receiving electrode bar 131e shown in (a) and Figure 13 The capacitance between the second direction driving electrode rod 111e and the second direction cross receiving electrode rod 131e shown in (b) can determine whether it is stretched in the first direction Y.

[0356] That is, when the capacitance increases or decreases, it can be determined that the stretch panel 100 is stretched in the first direction Y.

[0357] In addition, the stretching degree in the first direction Y can be determined by analyzing the capacitance change between the second direction driving electrode rod 111 e and the second direction cross receiving electrode rod 131 e.

[0358] That is, as the amount of change in capacitance increases, it can be determined that the stretch panel 100 is further stretched in the first direction Y.

[0359] In addition, by using the coordinates of the first direction driving electrode branch 111a provided with the stretch driving signal and the coordinates of the first direction cross receiving electrode branch 131a sensing the capacitance change, the coordinates of the area stretched in the first direction Y can be determined.

[0360] Figure 14 is an exemplary diagram showing a Z-axis stretching electrode of a device for sensing stretching according to an embodiment of the present disclosure, Figure 15A and 15B is shown along Figure 14 An example diagram of a cross section taken along line D-D' shown in FIG. Figure 16 The diagram is an example of three driving electrodes, three single receiving electrodes, three cross receiving electrodes and a Z-axis stretching electrode provided in a stretching panel of a stretch sensing device according to an embodiment of the present disclosure. Figures 1 to 13 The details described in (a) and (b) are the same or similar details.

[0361] As described above, the apparatus for sensing stretching according to an embodiment of the present disclosure can use the driving electrode TX, the single receiving electrode RX_X and the cross receiving electrode RX_Y to sense whether the stretch panel is stretched, for example, it can sense stretching in the first direction Y and stretching in the second direction X.

[0362] In addition, the stretch sensing device according to an embodiment of the present disclosure may further include: Figure 14 The Z-axis stretch electrode TZ is shown to further sense stretching in a third direction (eg, Z-axis direction) perpendicular to the first direction Y and the second direction X. In the following description, the third direction may be denoted by reference numeral Z.

[0363] For example, when the stretch panel 100 is stretched in the second direction X, the lengths of the second direction driving electrode 112 and the single receiving electrode RX_X are as shown in FIG. Figure 11 The increase causes the distance F between the first direction driving electrode bar 112e and the first direction single-receiving electrode bar 121e to change. Therefore, the capacitance between the first direction driving electrode bar 112e and the first direction single-receiving electrode bar 121e changes.

[0364] The stretching driver 60 may analyze the size of the capacitance changed between the first-direction driving electrode rod 112e and the first-direction single-receiving electrode rod 121e to determine whether it is stretched in the second direction X and the degree of stretching in the second direction X.

[0365] In this case, when the stretch panel 100 is stretched in the second direction X, the area of the stretch panel 100 may increase, and the height of the stretch panel 100 in the region where the stretching has occurred may decrease.

[0366] In addition, as referenced Figure 13 As described in (a) and (b), when the stretch panel 100 is stretched in the first direction Y, the area of the stretch panel 100 may increase, and the height of the stretch panel 100 in the region where the stretching has occurred may decrease.

[0367] That is, when the stretch panel 100 is stretched in the second direction X or the first direction Y, pressure may be applied to the stretch panel 100 in the third direction Z, and thus the height of the stretch panel 100 in the third direction Z may be reduced.

[0368] In particular, the height in the third direction Z in the region where the stretch is directly generated in the stretch panel 100 may be smaller than the height in the third direction Z around the region where the stretch is directly generated in the stretch panel 100 .

[0369] Therefore, if the height variation of the stretch panel 100 in the third direction Z is sensed, the stretch degree can be determined more accurately.

[0370] To this end, the stretch sensing device according to an embodiment of the present disclosure may further include: Figure 14 、 15A and the Z-axis stretched electrode TZ shown in FIG15B.

[0371] First, the stretch panel 100 of the device for sensing stretching according to an embodiment of the present disclosure may also include a main pressure electrode 141a arranged on a stretching support substrate 101, an auxiliary pressure electrode 142a arranged to overlap with the main pressure electrode 141a in a third direction Z perpendicular to the first direction Y and the second direction X (with a Z-axis insulating layer 143 interposed therebetween), a main pressure electrode line 141b connecting the main pressure electrodes 141a arranged along the first direction Y among the main pressure electrodes 141a, and an auxiliary pressure electrode line 142b connecting the auxiliary pressure electrodes 142a arranged along the second direction X among the auxiliary pressure electrodes 142a.

[0372] For example, the Z-axis tension electrode TZ may further include a main pressure electrode 141 a , an auxiliary pressure electrode 142 a , a main pressure electrode line 141 b , and an auxiliary pressure electrode line 142 b .

[0373] The main pressure electrodes 141 a disposed in the first direction Y and the main pressure electrode lines 141 b connecting the main pressure electrodes 141 a among the main pressure electrodes 141 a may be included in the main electrode 141 .

[0374] Auxiliary pressure electrodes 142 a arranged in the second direction X and auxiliary pressure electrode lines 142 b connecting the auxiliary pressure electrodes 142 a among the auxiliary pressure electrodes 142 a may be included in the auxiliary electrode 142 .

[0375] That is, the Z-axis tension electrode TZ may include a main electrode 141 and an auxiliary electrode 142 .

[0376] In particular, the Z-axis tension electrode TZ may include at least two main electrodes 141 and at least two auxiliary electrodes 142 .

[0377] Then, if Figure 14 As shown in , each of the main electrodes 141 may extend in the first direction Y, and the main electrodes 141 may be spaced apart in the second direction X.

[0378] In addition, each of the auxiliary electrodes 142 may extend along the second direction X, as shown in FIG. Figure 14 As shown in , the auxiliary electrodes 142 may be spaced apart along the first direction Y.

[0379] In this case, if Figure 15A and 15B As shown, the main pressure electrode 141 a and the auxiliary pressure electrode 142 a may overlap each other in the third direction Z with a Z-axis insulating layer 143 therebetween.

[0380] For example, Figure 15A As shown, the stretching support substrate 101 can be bonded to the stretching substrate 103 by an adhesive 102, the auxiliary pressure electrode 142a can be set on the upper surface of the stretching substrate 103, the auxiliary pressure electrode 142a can be covered by the Z-axis insulating layer 143, the main pressure electrode 141a can be set on the upper surface of the Z-axis insulating layer 143, and the main pressure electrode 141a can be covered by the stretching passivation layer 105.

[0381] in this case, Figure 15A The tensile support substrate 101, adhesive 102, tensile substrate 103, and tensile passivation layer 105 shown in FIG may correspond to the reference Figure 6 The tensile support substrate 101 , adhesive 102 , tensile substrate 103 and tensile passivation layer 105 are described.

[0382] also, Figure 15A The auxiliary pressure electrode 142a shown can be arranged at the same position as the reference Figure 6 The bridge 106 is described as being provided on the same layer, for example, on the same layer as the drive electrode bridge 111 b and the cross-reception electrode bridge 131 b .

[0383] also, Figure 15A The main pressure electrode 141a shown can be arranged with reference Figure 6 The metal electrode 104 is described as being on the same layer, for example, being provided on the same layer as the second direction driving electrode 112 , the single receiving electrode RX_X, and the second direction cross receiving electrode 132 .

[0384] In addition, Figure 15A , a tensile panel 100 is shown in which the main pressure electrode 141 a is disposed on the auxiliary pressure electrode 142 a , but the auxiliary pressure electrode 142 a may be disposed on the main pressure electrode 141 a .

[0385] In addition, as referenced Figure 6 As described above, the tensile substrate 103 may include mesh portions 103 a connected like a mesh, and the opening portions 103 b may be formed between the mesh portions 103 a.

[0386] In this case, the main pressure electrode 141 a and the auxiliary pressure electrode 141 b may be provided only in the mesh portion 103 a .

[0387] The main pressure electrode line 141b can also be arranged on the upper surface of the stretching substrate 103, in particular, as shown in FIG. Figure 14 As shown, in the first direction Y. The main pressure electrode lines 141 b may be connected to the main pressure electrodes 141 a , and thus, the main electrodes 141 may be formed.

[0388] The auxiliary pressure electrode lines 142b may also be provided on the upper surface of the stretching substrate 103, in particular, as shown in FIG. Figure 14 As shown, in the second direction X. The auxiliary pressure electrode line 142 b may be connected to the auxiliary pressure electrode 142 a , and thus, the auxiliary electrode 142 may be formed.

[0389] The sizes of the main pressure electrode 141a and the auxiliary pressure electrode 142a may be the same or different. In this case, the size of the main pressure electrode 141a may be larger than that of the auxiliary pressure electrode 142a, or the size of the auxiliary pressure electrode 142a may be larger than that of the main pressure electrode 141a.

[0390] In addition, if Figure 15BAs shown, a first surface (e.g., an upper surface) of the tensile support substrate 101 can be bonded to the tensile substrate 103 via an adhesive 102, a main pressure electrode 141a can be provided on the upper surface of the tensile substrate 103, and the main pressure electrode 141a can be covered by the tensile passivation layer 105. A second surface (e.g., a lower surface) of the tensile support substrate 101 opposite to the first surface can be bonded to a lower tensile substrate 1031 via a lower adhesive 1021, an auxiliary pressure electrode 142a can be provided on the lower surface of the lower tensile substrate 1031, and the auxiliary pressure electrode 142b can be covered by the lower tensile passivation layer 1051.

[0391] in this case, Figure 15B The tensile support substrate 101, adhesive 102, tensile substrate 103, and tensile passivation layer 105 shown in FIG may correspond to the reference Figure 6 The tensile support substrate 101 , adhesive 102 , tensile substrate 103 and tensile passivation layer 105 are described.

[0392] also, Figure 15B The main pressure electrode 141a shown in FIG can be set to Figure 6 The bridge 106 is described as being provided on the same layer, for example, on the same layer as the drive electrode bridge 111 b and the cross-reception electrode bridge 131 b .

[0393] also, Figure 15B The lower adhesive 1021 , the lower tensile substrate 1031 , and the lower tensile passivation layer 1051 shown in may correspond to the adhesive 102 , the tensile substrate 103 , and the tensile passivation layer 105 .

[0394] also, Figure 15B The tensile panel 100 is shown in which the main pressure electrode 141a is provided on the tensile support substrate 101, and the auxiliary pressure electrode 142a is provided at the lower end of the tensile support substrate 101. However, the main pressure electrode 141a may be provided at the lower end of the tensile support substrate 101, and the auxiliary pressure electrode 142a may be provided at the upper end of the tensile support substrate 101.

[0395] In addition, as referenced Figure 15A As described above, the main pressure electrodes 141 a may be provided only in the mesh portion 103 a of the tension substrate 103 , and the auxiliary pressure electrodes 142 a may be provided only in the mesh portion of the lower tension substrate 1031 .

[0396] The main pressure electrode line 141b may be provided on the upper surface of the stretching substrate 103, in particular, as shown in FIG. Figure 14 As shown, in the first direction Y. The main pressure electrode line 141 b may be connected to the main pressure electrode 141 a , and thus may form the main electrode 141 .

[0397] The auxiliary pressure electrode lines 142b may be provided on the lower surface of the lower tensile substrate 1031, in particular, as shown in FIG. Figure 14 As shown, in the second direction X. The auxiliary pressure electrode line 142 b may be connected to the auxiliary pressure electrode 142 a , and thus, the auxiliary electrode 142 may be formed.

[0398] Next, each of the main pressure electrode lines 141 b and the auxiliary pressure electrode lines 142 b may have a circular shape with peaks and valleys.

[0399] For example, in Figure 14 In the main pressure electrode line 141b shown in FIG, a peak portion indicates a portion protruding in the left direction, and a valley portion indicates a portion protruding in the right direction.

[0400] That is, the main pressure electrode line 141 b may include at least one peak portion protruding in the left direction and at least one valley portion protruding in the right direction, and thus may have a circular shape.

[0401] As described above, since the main pressure electrode line 141 b has a circular shape provided with peaks and valleys along the first direction Y, the main pressure electrode line 141 b may be stretched along the first direction Y.

[0402] In addition, Figure 14 In the auxiliary pressure electrode line 142 b shown, the peak portion indicates a portion protruding upward, and the valley portion indicates a portion protruding downward.

[0403] That is, the auxiliary pressure electrode line 142b may include at least one peak portion protruding in an upper direction and at least one valley portion protruding in a lower direction, and thus may have a circular shape.

[0404] As described above, since the auxiliary pressure electrode line 142 b has a circular shape provided with peaks and valleys along the second direction X, the auxiliary pressure electrode line 142 b may be stretched along the second direction X.

[0405] Next, if Figure 16 As shown, the main pressure electrode 141 a and the auxiliary pressure electrode 142 a may be disposed in a region where the driving electrode TX, the single receiving electrode RX_X, and the cross receiving electrode RX_Y are not disposed.

[0406] The main pressure electrode lines 141 b are arranged along the first direction Y, and the second direction driving electrodes 112 , the single receiving electrodes RX_X, and the second direction cross receiving electrodes 132 are arranged along the second direction X.

[0407] Therefore, the main pressure electrode line 141 b may be adjacent to the second direction driving electrode 112 , the single receiving electrode RX_X, and the second direction cross-receiving electrode 132 , and in particular, may intersect the single receiving electrode RX_X and the second direction cross-receiving electrode 132 .

[0408] Therefore, if Figure 16 As shown, in the third area AR3 where the main pressure electrode line 141b intersects the single receiving electrode RX_X and the second direction crossing receiving electrode 132, the main pressure electrode line 141b may overlap with the single receiving electrode RX_X and the second direction crossing receiving electrode 132 with an insulating layer interposed therebetween.

[0409] For example, the reference electrode RX_X may be set in the third area AR3 where the main pressure electrode line 141b overlaps with the single receiving electrode RX_X and the second direction cross receiving electrode 132. Figure 15A and 15B The Z-axis insulating layer 143 described corresponds to the insulating layer.

[0410] In this case, the main pressure electrode line 141b may be disposed at a lower end of the insulating layer disposed in the third area AR3, and the single receiving electrode RX_X and the second direction cross receiving electrode 132 may be disposed at an upper end of the insulating layer disposed in the third area AR3.

[0411] However, the main pressure electrode line 141b may be disposed at an upper end of the insulating layer disposed in the third area AR3, and the single receiving electrode RX_X and the second direction cross receiving electrode 132 may be disposed at a lower end of the insulating layer disposed in the third area AR3.

[0412] In addition, a Z-axis bridge may be provided in the third area AR3 to connect the main pressure electrode wires 141 b connected to different main pressure electrodes 141 a .

[0413] For example, the Z-axis bridge member may be provided on a different layer from the main pressure electrode line 141b, the single receiving electrode RX_X, and the second-direction cross-receiving electrode 132, with an insulating layer therebetween. In this case, the main pressure electrode line 141b may be connected to the Z-axis bridge member via a contact hole provided in the insulating layer, so that two main pressure electrode lines 141b connected to different main pressure electrodes 141a may be connected to each other via the Z-axis bridge member. However, the main pressure electrode line 141b may be directly connected to the Z-axis bridge member at the end of the Z-axis bridge member.

[0414] The second direction driving electrodes 112 may be disposed to be spaced apart from each other in the third area AR3 .

[0415] The auxiliary pressure electrode lines 142 b are arranged along the second direction X, and the first direction driving electrodes 111 and the first direction crossing receiving electrodes 131 are arranged along the first direction Y.

[0416] Therefore, the auxiliary pressure electrode line 142 b may be adjacent to the first direction driving electrode 111 and the first direction crossing receiving electrode 131 , and in particular, may intersect the first direction driving electrode 111 .

[0417] Therefore, if Figure 16 As shown, in the fourth region AR4 where the auxiliary pressure electrode line 142 b intersects the first direction driving electrode 111 , the auxiliary pressure electrode line 142 b may overlap with the first direction driving electrode 111 with an insulating layer interposed therebetween.

[0418] For example, the auxiliary pressure electrode line 142b may be provided in the fourth region AR4 where the auxiliary pressure electrode line 142b intersects the first direction driving electrode 111. Figure 15A and 15B The Z-axis insulating layer 143 described corresponds to the insulating layer.

[0419] In this case, the auxiliary pressure electrode line 142b may be disposed at a lower end of the insulating layer disposed in the fourth area AR4, and the first direction driving electrode 111 may be disposed at an upper end of the insulating layer disposed in the fourth area AR4.

[0420] However, the auxiliary pressure electrode line 142b may be disposed at an upper end of the insulating layer disposed in the fourth area AR4, and the first direction driving electrode 111 may be disposed at a lower end of the insulating layer disposed in the fourth area AR4.

[0421] In addition, if Figure 14 and 16 As shown, a Z-axis bridge 142 c for connecting the auxiliary pressure electrode lines 142 b connected to different auxiliary pressure electrodes 142 a may be provided in the fourth area AR4 .

[0422] For example, the Z-axis bridge 142c may be provided in a layer different from the auxiliary pressure electrode lines 142b and the first direction drive electrodes 111, with an insulating layer therebetween. In this case, the auxiliary pressure electrode lines 142b may be connected to the Z-axis bridge 142c via contact holes provided in the insulating layer, so that two auxiliary pressure electrode lines 142b connected to different auxiliary pressure electrodes 142a may be connected to each other via the Z-axis bridge 142c. However, the auxiliary pressure electrode lines 142b may be directly connected to the Z-axis bridge at the ends of the Z-axis bridge.

[0423] The first-direction cross-receiving electrodes 131 may be disposed to be spaced apart from each other in the fourth area AR4 .

[0424] Finally, a method of determining whether to be stretched in the third direction Z or to be compressed in the third direction Z by using the Z-axis tension electrode TZ will be described.

[0425] For example, as described above, when the stretch panel 100 is stretched in the second direction X or the first direction Y, pressure may be applied to the stretch panel 100 in the third direction Z, and thus the height of the stretch panel 100 in the third direction Z may be reduced.

[0426] When the height of the tensile panel 100 in the third direction Z is reduced, Figure 15A and 15B A gap Z1 is shown between the main pressure electrode 141a and the auxiliary pressure electrode 142a.

[0427] The tensile driving signal may be provided from the tensile driver 60 to at least one of the main pressure electrode 141 a and the auxiliary pressure electrodes 142 a , for example, the tensile driving signal may be provided to the main pressure electrode 141 a .

[0428] Therefore, capacitance may be formed between the main pressure electrode 141 a and the auxiliary pressure electrode 142 a .

[0429] In this case, if the stretch panel 100 is stretched in the first direction Y or the second direction X and the height in the third direction Y is reduced, the gap Z1 between the main pressure electrode 141a and the auxiliary pressure electrode 142a can be reduced, and thus the capacitance between the main pressure electrode 141a and the auxiliary pressure electrode 142a can be changed.

[0430] Therefore, at least one of current, voltage, and capacitance of a signal sensing stretch received through the auxiliary electrodes 142 including the auxiliary pressure electrodes 142 a may be changed.

[0431] The stretch driver 60 may analyze a change in at least one of current, voltage, and capacitance to determine whether the stretch panel 100 is stretched in the third direction Z, at least one of a stretch degree in the third direction Z, and a stretch coordinate at which the stretch occurs in the third direction Z.

[0432] In particular, the stretch driver 60 may analyze stretch-sensing signals received through the single receiving electrode RX_X, the cross receiving electrode RX_Y, and the auxiliary electrode 142 to determine at least one of whether they are stretched, the degree of stretch, and the stretch coordinates where the stretch occurs.

[0433] Therefore, a more accurate stretch state (eg, whether it is stretched), stretch degree, and stretch coordinates can be determined.
