These symbols are provided only to distinguish one component from another, and the nature, order, or number of the components is not limited by these symbols in order or sequence.

[0039] When describing the positional relationship between components, when two or more components are described as being “connected,” “coupled,” or “linked,” the two or more components may be directly “connected,” “coupled,” or “linked,” or another component may be inserted. Here, another component may be included in one or more of the two or more components that are “connected,” “coupled,” or “linked” to each other.

[0042] Hereinafter, various embodiments of the present disclosure are described in detail with reference to the accompanying drawings.

[0043] Figure 1 is a view showing a system configuration of a display device 100 according to an embodiment of the present disclosure.

[0044] Reference Figure 1 The display device 100 according to an embodiment of the present disclosure may include a display panel 110 and a display driving circuit as components for displaying an image. The display driving circuit is a circuit for driving the display panel 110 and may include a data driving circuit 120, a gate driving circuit 130, and a display controller 140.

[0045] The display panel 110 may include a substrate 111 , a plurality of sub-pixels SP disposed on the substrate 111 , and various signal lines disposed on the substrate 111 to drive the plurality of sub-pixels SP.

[0046] The substrate 111 may include a display area DA where a plurality of sub-pixels SP are disposed and a non-display area NDA positioned in a first direction with respect to the display area DA.

[0047] The non-display area NDA may include a pad area for connection with the data driving circuit 120. For example, the pad area may be positioned in the non-display area NDA in the first direction.

[0048] The non-display area NDA may have only as large a size as, for example, a pad area that it may include. In other words, the non-display area NDA of the display panel 110 according to an embodiment of the present disclosure may have a very small size. For example, although the display panel 110 has the non-display area NDA, the boundary area between the display area and the non-display area NDA may be bent so that the non-display area NDA may be located below the display area DA. In this case, the non-display area NDA shown to the user may not change or hardly change when the user views the display area DA from the front.

[0049] The display device 100 according to the embodiment of the present disclosure may be a liquid crystal display device or a self-luminous display device in which the display panel 110 emits light itself. When the display device 100 according to the embodiment of the present disclosure is a self-luminous display device, each of the plurality of sub-pixels SP may include a light-emitting element.

[0050] For example, the display device 100 according to an embodiment of the present disclosure may be an organic light emitting diode display, in which the light emitting element is implemented as an organic light emitting diode (OLED). As another example, the display device 100 according to an embodiment of the present disclosure may be an inorganic light emitting display device, in which the light emitting element is implemented as a light emitting diode based on an inorganic material. As another example, the display device 100 according to an embodiment of the present disclosure may be a quantum dot display device, in which the light emitting element is implemented as a quantum dot as a self-luminous semiconductor crystal.

[0051] The structure of each of the plurality of subpixels SP may vary according to the type of the display device 100. For example, when the display device 100 is a self-luminous display device in which the subpixel SP emits light itself, each subpixel SP may include a self-luminous light emitting element, one or more transistors, and one or more capacitors.

[0052] For example, the various types of signal lines may include a plurality of data lines DL transmitting data signals (also referred to as data voltages or image signals) and a plurality of gate lines GL transmitting gate signals (also referred to as scan signals).

[0053] A plurality of data lines DL and a plurality of gate lines GL may cross each other. Each of the plurality of data lines DL may be arranged to extend in a first direction. Each of the plurality of gate lines GL may be arranged to extend in a second direction. Here, the first direction may be a column direction, and the second direction may be a row direction. The first direction may be a row direction, and the second direction may be a column direction. For ease of description, the following example is described: each of the plurality of data lines DL is arranged in a column direction, and each of the plurality of gate lines GL is arranged in a row direction, and the first direction is a column direction, and the second direction is a row direction.

[0054] The data driving circuit 120 is a circuit for driving the plurality of data lines DL, and may output data signals to the plurality of data lines DL.

[0057] The data driving circuit 120 may be disposed outside the display area DA of the display panel 110 , but alternatively, the data driving circuit 120 may be disposed in the display area DA of the display panel 110 .

[0058] The gate driving circuit 130 is a circuit for driving the plurality of gate lines GL, and may output gate signals to the plurality of gate lines GL.

[0060] In the display device 100 according to an embodiment of the present disclosure, the gate driving circuit 130 may be disposed to overlap with the display area DA of the display panel 110. For example, the gate driving circuit 130 may be disposed in the entire display area DA, or may be disposed only in a portion (e.g., two opposite sides) of the display area DA. When the gate driving circuit 130 is disposed to overlap with the display area DA, the gate driving circuit 130 may be disposed not to overlap with the sub-pixels SP, or may be disposed to overlap with all or some of the sub-pixels SP.

[0061] In the display device 100 according to an embodiment of the present disclosure, the gate driving circuit 130 may be embedded in the display panel 110 in a gate-in-panel (GIP) type. When the gate driving circuit 130 is a gate-in-panel type, the gate driving circuit 130 may be formed on a substrate 111 of the display panel 110 during a manufacturing process of the display panel 110.

[0062] The display controller 140 is a device for controlling the data driving circuit 120 and the gate driving circuit 130 , and may control a driving timing of a plurality of data lines DL and a driving timing of a plurality of gate lines GL.

[0063] The display controller 140 may supply a data driving control signal DCS to the data driving circuit 120 to control data driving, and may supply a gate driving control signal GCS to the gate driving circuit 130 to control gate driving.

[0064] The display controller 140 may receive input image data from the host system 180 and supply image data DATA to the data driving circuit 120 based on the input image data.

[0065] The display controller 140 may be implemented as a separate component from the data driving circuit 120 , or the display controller 140 and the data driving circuit 120 may be integrated into an integrated circuit (IC).

[0066] The display controller 140 may be a timing controller used in a typical display technology, a control device that may perform other control functions as well as the functions of the timing controller, or a control device other than the timing controller, or may be a circuit in the control device. The display controller 140 may be implemented as various circuits or electronic components, such as an integrated circuit (IC), a field programmable gate array (FPGA), an application specific integrated circuit (ASIC), or a processor.

[0067] The display controller 140 may be mounted on a printed circuit board or a flexible printed circuit, and may be electrically connected to the data driving circuit 120 and the gate driving circuit 130 through the printed circuit board or the flexible printed circuit.

The interfaces may include, for example, a low voltage differential signaling (LVDS) interface, an embedded clock point-to-point interface (EPI), and a serial peripheral interface (SPI).

[0069] Meanwhile, the display device 100 according to an embodiment of the present disclosure may include a touch sensor and a touch sensing circuit 150 to further provide a touch sensing function and an image display function.

[0070] The touch sensing circuit 150 may detect the presence of a touch (finger touch or pen touch) by a touch object such as a finger or a pen 10 , or detect a touch position by sensing the touch sensor.

[0071] For example, the touch sensing circuit 150 may include a touch driving circuit 160 that drives and senses a touch sensor and generates and outputs touch sensing data, and a touch controller 170 that may detect the occurrence of a touch or a touched position using the touch sensing data.

[0072] The touch sensor may include a plurality of sensor electrodes. Here, the touch sensor may also be referred to as a touch panel or a touch screen panel (TSP).

[0073] The touch sensor may be an external type existing on the outside of the display panel 110 , or may be an internal type existing on the inside of the display panel 110 .

[0074] When the touch sensor is an external type, the touch sensor and the display panel 110 may be manufactured separately or may be combined during an assembly process. The external type touch sensor may include a substrate and a plurality of sensor electrodes on the substrate.

[0075] When the touch sensor is an internal type, a plurality of sensor electrodes and various patterns for display driving may be formed in the display panel 110 during a manufacturing process of the display panel 110 .

[0076] The touch driving circuit 160 may supply a touch driving signal to at least one of the plurality of sensor electrodes, and may sense at least one of the plurality of sensor electrodes to generate touch sensing data.

[0077] The touch sensing circuit 150 may perform touch sensing in a self-capacitance sensing scheme or a mutual capacitance sensing scheme.

[0078] When the touch sensing circuit 150 performs touch sensing in a self-capacitance sensing scheme, the touch sensing circuit 150 may perform touch sensing based on the capacitance between each sensor electrode and a touch object (e.g., a finger or pen 10). According to the self-capacitance sensing scheme, each of the plurality of sensor electrodes may be used as a transmitting sensor electrode as well as a receiving sensor electrode. The touch drive circuit 160 may drive all or some of the plurality of sensor electrodes and sense all or some of the plurality of sensor electrodes.

[0079] When the touch sensing circuit 150 performs touch sensing in a mutual capacitance sensing scheme, the touch sensing circuit 150 may perform touch sensing based on the capacitance between the plurality of sensor electrodes. According to the mutual capacitance sensing scheme, the plurality of sensor electrodes may be divided into a plurality of transmitting sensor electrodes and a plurality of receiving sensor electrodes. The touch driving circuit 160 may drive the plurality of transmitting sensor electrodes and the plurality of receiving sensor electrodes.

[0080] Hereinafter, the transmitting sensor electrode is also referred to as a driving sensor electrode, and the receiving sensor electrode is also referred to as a detecting sensor electrode.

[0081] The touch driving circuit 160 and the touch controller 170 included in the touch sensing circuit 150 may be implemented as separate devices or as a single device.

[0082] The touch driving circuit 160 and the data driving circuit 120 may be implemented as separate devices or as a single device. For example, the touch driving circuit 160 and the data driving circuit 120 may be configured as a single integrated circuit.

[0087] Reference Figure 2, when the display device 100 according to an embodiment of the present disclosure is a self-luminous display device, each of the plurality of sub-pixels SP may include a light emitting element ED and a sub-pixel circuit unit SPC for driving the light emitting element ED.

[0088] Reference Figure 2 , the sub-pixel circuit unit SPC may include a plurality of pixel driving transistors for driving the light emitting element ED and at least one capacitor.

[0089] The plurality of pixel driving transistors may include a first transistor T1 serving as a driving transistor for driving the light emitting element ED and a second transistor T2 for transmitting a data signal VDATA to a second node N2 of the first transistor T1 .

[0090] The at least one capacitor may include a storage capacitor Cst for maintaining a constant voltage during a frame.

[0091] To drive the subpixel SP, a data signal VDATA as an image signal and a scan signal SC as a gate signal may be applied to the subpixel SP. In addition, to drive the subpixel SP, a common pixel driving voltage including a first driving voltage VDD and a second driving voltage VSS may be applied to the subpixel SP.

The pixel electrode PE may be electrically connected to the first node N1 of the first transistor T1 of each subpixel SP.

[0095] For example, the pixel electrode PE may be an anode, and the common electrode CE may be a cathode. Conversely, the pixel electrode PE may be a cathode, and the common electrode CE may be an anode. For ease of description, it is assumed below that the pixel electrode PE is an anode, and the common electrode CE is a cathode.

[0096] Each of the light emitting elements ED may include a portion where the pixel electrode PE, the element intermediate layer EL, and the common electrode CE overlap each other. A predetermined light emitting region may be formed by each light emitting element ED. For example, the light emitting region of each light emitting element ED may include a region where the pixel electrode PE, the element intermediate layer EL, and the common electrode CE overlap.

[0097] For example, the light emitting element ED may be an organic light emitting diode (OLED), an inorganic light emitting diode (LED), or a quantum dot light emitting element.

[0101] The second transistor T2 may be a switching transistor for transmitting the data signal VDATA, which is an image signal, to the second node N2, which is a gate node of the first transistor T1, which is a driving transistor.

[0102] The second transistor T2 may be controlled to be turned on and off by a scan signal SC to control the electrical connection between the second node N2 of the first transistor T1 and the data line DL, the scan signal SC being a gate signal applied through a scan line SCL, which is a type of gate line GL. A drain electrode or a source electrode of the second transistor T2 may be electrically connected to the data line DL, a source electrode or a drain electrode of the second transistor T2 may be electrically connected to the second node N2 of the first transistor T1, and a gate electrode of the second transistor T2 may be electrically connected to the scan line SCL.

The storage capacitor Cst may include a first capacitor electrode electrically connected to the first node N1 of the first transistor T1 or corresponding to the first node N1 of the first transistor T1, and a second capacitor electrode electrically connected to the second node N2 of the first transistor T1 or corresponding to the second node N2 of the first transistor T1.

[0104] Each of the first transistor T1 and the second transistor T2 may be an n-type transistor or a p-type transistor.

[0105] At least a portion of the sub-pixel circuit unit SPC may overlap at least a portion of the light emitting element ED in the vertical direction. Alternatively, the sub-pixel circuit unit SPC may not overlap with the light emitting element ED in the vertical direction.

[0106] like Figure 2 As shown, the sub-pixel circuit unit SPC may have a 2T (transistor) 1C (capacitor) structure including two transistors T1 and T2 and one capacitor Cst. In some cases, the sub-pixel circuit unit SPC may further include one or more transistors, or may further include one or more capacitors.

[0107] According to the structure of the subpixel circuit unit SPC, the type and number of gate signals supplied to the subpixels SP and the gate lines may vary. In addition, the type and number of common pixel driving voltages supplied to the subpixels SP may vary according to the structure of the subpixel circuit unit SPC.

[0108] Since the circuit elements in each sub-pixel SP (especially the light emitting element ED implemented as an organic light emitting diode (OLED) including an organic material) are susceptible to external moisture or oxygen, an encapsulation layer 200 for preventing external moisture or oxygen from penetrating into the circuit elements (especially the light emitting element ED) may be provided on the display panel 110.

[0117] Reference Figure 3 The plurality of sensor electrodes SE may include a plurality of transmission sensor electrodes SE_TX and a plurality of reception sensor electrodes SE_RX. The plurality of traces TL may include a plurality of transmission traces TL_TX and a plurality of reception traces TL_RX. The plurality of pads PD may include a plurality of transmission pads PD_TX and a plurality of reception pads PD_RX.

[0118] The touch drive signal output from the touch drive circuit 160 may be applied to at least one of the plurality of transmission sensor electrodes SE_TX. Here, the touch drive signal may be a signal whose voltage level changes. For example, the touch drive signal may be a pulse signal having a predetermined frequency and amplitude, and may be a signal having various signal waveforms such as a triangular wave, a spherical wave, or a sine wave.

[0119] Reference Figure 3 , the plurality of transmission sensor electrodes SE_TX and the plurality of reception sensor electrodes SE_RX may be arranged to cross each other. For example, each of the plurality of transmission sensor electrodes SE_TX may be arranged to extend in a first direction. Each of the plurality of reception sensor electrodes SE_RX may be arranged to extend in a second direction different from the first direction.

[0120] The shape of each of the plurality of transmitting sensor electrodes SE_TX and the plurality of receiving sensor electrodes SE_RX may be variously modified. For example, each of the plurality of transmitting sensor electrodes SE_TX and the plurality of receiving sensor electrodes SE_RX may have a bar shape. As another example, each of the plurality of receiving sensor electrodes SE_RX may be composed of a plurality of electrically connected sub-sensor electrodes, or each of the plurality of transmitting sensor electrodes SE_TX may be composed of a plurality of electrically connected sub-sensor electrodes. For example, each of the plurality of sub-sensor electrodes may have various shapes, such as a square, a diamond, or a comb pattern.

[0121] Reference Figure 3 When the internal trace structure of the display panel 110 according to an embodiment of the present disclosure is applied, one of the multiple transmitting traces TL_TX or the multiple receiving traces TL_RX can extend across the display area DA to the pad area PA without bypassing the non-display area NDA outside the display area DA.

[0122] For example, the plurality of receiving traces TL_RX among the plurality of transmitting traces TL_TX or the plurality of receiving traces TL_RX may extend across the display area DA to the pad area PA without bypassing the non-display area NDA outside the display area DA. When the plurality of receiving traces TL_RX cross the display area DA, the plurality of receiving traces TL_RX may be arranged to avoid the light emitting area of ​​each of the plurality of sub-pixels SP in the display area DA. Therefore, the internal trace structure may be designed without deteriorating the light emitting performance.

[0123] In this case, the plurality of reception traces TL_RX may cross the plurality of reception sensor electrodes SE_RX. In other words, the plurality of reception traces TL_RX may be located in a different metal layer from the plurality of reception sensor electrodes SE_RX and may overlap the plurality of reception sensor electrodes SE_RX.

[0124] According to the internal trace structure of the display panel 110 according to an embodiment of the present disclosure, the size of the non-display area NDA may be significantly reduced.

[0125] Reference Figure 3 , the non-display area NDA may include a first non-display area NDA1 positioned in a first direction relative to the display area DA, a second non-display area NDA2 positioned in a second direction relative to the display area DA, a third non-display area NDA3 positioned in a direction opposite to the first direction relative to the display area DA, and a fourth non-display area NDA4 positioned in a direction opposite to the second direction relative to the display area DA. That is, the first non-display area NDA1 is below the display area DA (e.g., a first side of the display area DA), the second non-display area NDA2 is at the right side of the display area DA (e.g., a second side of the display area DA), the third non-display area NDA3 is above the display area DA (e.g., a third side of the display area DA), and the fourth non-display area NDA4 is at the left side of the display area DA (e.g., a fourth side of the display area DA).

[0126] Reference Figure 3 , when the internal trace structure of the display panel 110 according to an embodiment of the present disclosure is applied, the plurality of traces TL may be disposed in the first non-display area NDA1 including the pad area PA among the first to fourth non-display areas NDA1 to NDA4, but the plurality of traces TL may not be disposed in the second non-display area NDA2 and the fourth non-display area NDA4.

[0127] Therefore, the sizes of the second non-display area NDA2 and the fourth non-display area NDA4 among the first to fourth non-display areas NDA1 to NDA4 may be reduced to the limit.

[0128] Reference Figure 3 , the plurality of transmitting sensor electrodes SE_TX and the plurality of receiving sensor electrodes SE_RX may include a sensor metal SM.

[0129] The plurality of transmission traces TL_TX or the plurality of reception traces TL_RX may cross the plurality of transmission sensor electrodes SE_TX or the plurality of reception sensor electrodes SE_RX. Therefore, the plurality of transmission traces TL_TX or the plurality of reception traces TL_RX may include a bridge metal BM different from a sensor metal SM included in the plurality of transmission sensor electrodes SE_TX or the plurality of reception sensor electrodes SE_RX.

[0130] For example, Figure 3As shown, among the plurality of transmission traces TL_TX and the plurality of reception traces TL_RX, the plurality of reception traces TL_RX may pass through the display area DA and simultaneously cross the plurality of reception sensor electrodes SE_RX.

[0131] In this case, the plurality of reception traces TL_RX may include a bridge metal BM different from the sensor metal SM. In this case, the plurality of transmission traces TL_TX may include the sensor metal SM or the bridge metal BM.

[0132] As another example, among the plurality of transmission traces TL_TX and the plurality of reception traces TL_RX, the plurality of transmission traces TL_TX may cross the plurality of transmission sensor electrodes SE_TX while passing through the display area DA. In this case, the plurality of transmission traces TL_TX may include a bridge metal BM different from the sensor metal SM. In this case, the plurality of reception traces TL_RX may include the sensor metal SM or the bridge metal BM.

[0133] Meanwhile, outside the display area DA (i.e., in the first non-display area NDA1), the trace TL may be changed from the sensor metal SM to the bridge metal BM or from the bridge metal BM to the sensor metal SM. If necessary, a third metal different from the sensor metal SM and the bridge metal BM may be used as some metals of the trace TL.

[0134] In the following, reference is made to Figure 4 , Figure 5 , Figure 6 and Figure 7 describe Figure 3 However, in describing Figure 4 , Figure 5 , Figure 6 and Figure 7 When the touch sensor is Figure 3 The features of the touch sensor are the same as those of the previous description, and the different features will be mainly described.

[0135] Figure 4 is another plan view illustrating a touch sensor included in the display panel 110 according to an embodiment of the present disclosure.

[0136] Reference Figure 4 , the touch sensor included in the display panel 110 according to the embodiment of the present disclosure may have a resistance equivalent design structure.

[0137] The number of reception traces TL_RX connected to one of the plurality of reception sensor electrodes SE_RX farthest from the pad area PA may be greater than the number of reception traces TL_RX connected to one of the plurality of reception sensor electrodes SE_RX closest to the pad area PA.

[0138] For example, Figure 4 As shown, two receiving traces TL_RXa and TL_RXb can be connected to each of the two opposite ends of a receiving sensor electrode SE_RX farthest from the pad area PA among the multiple receiving sensor electrodes SE_RX, and one receiving trace TL_RX can be connected to each of the two opposite ends of a receiving sensor electrode SE_RX closest to the pad area PA among the multiple receiving sensor electrodes SE_RX.

[0139] Reference Figure 4 , the first trace TL1 connected to one end of the first sensor electrode SE1 as the farthest one receiving sensor electrode SE_RX may include two receiving traces TL_RXa and TL_RXb overlapping with the display area DA and extending in the first direction. Similarly, the first trace TL1 connected to the other end of the first sensor electrode SE1 may include two receiving traces TL_RXa and TL_RXb overlapping with the display area DA and extending in the first direction. The two receiving traces TL_RXa and TL_RXb included in the first trace TL1 connected to one end of the first sensor electrode SE1 may be physically connected in the non-display area NDA. The two receiving traces TL_RXa and TL_RXb included in the first trace TL1 connected to the other end of the first sensor electrode SE1 may be physically connected in the non-display area NDA.

[0140] Therefore, the two receiving traces TL_RXa and TL_RXb can be physically connected (i.e., merged into one) in the non-display area NDA to connect to one first pad PD1. Therefore, the number of pads in the pad area PA can be reduced, and the number of pads (the number of channels) of the touch drive circuit 160 can be reduced. For example, when the plurality of receiving sensor electrodes SE_RX are divided into n groups, the number of receiving traces TL_RX connected to the receiving sensor electrode SE_RX included in the first group closest to the pad area PA in the n groups may be 1, the number of receiving traces TL-RX connected to the receiving sensor electrode SE_RX included in the second group closest to the pad area PA in the n groups may be 2, the number of receiving traces TL_RX connected to the receiving sensor electrode SE_RX included in the third group closest to the pad area PA in the n groups may be 3, and the number of receiving traces TL_RX connected to the receiving sensor electrode SE_RX included in the nth group closest to the pad area PA in the n groups may be n.

[0141] According to the resistance equivalent design structure of the touch sensor included in the display panel 110 according to the embodiment of the present disclosure, even if there is a length deviation between the plurality of receiving traces TL_RX, the resistance deviation of the signal transmission path between the plurality of receiving sensor electrodes SE_RX and the plurality of receiving pads PD_RX can be reduced. Therefore, the touch sensitivity can be enhanced.

[0142] At the same time, refer to Figure 3 and Figure 4 In the touch sensor included in the display panel 110 according to an embodiment of the present disclosure, all of the multiple contact holes CNT connecting the multiple receiving sensor electrodes SE_RX and the multiple receiving traces TL_RX can be positioned further outside than the outermost transmitting trace TL_TX among the multiple transmitting traces TL_TX.

[0143] In other words, refer to Figure 3 and Figure 4 , the first trace TL1, the second trace TL2, the third trace TL3, and the fifth trace TL5 may be disposed to extend in the first direction relative to a boundary region in the display area DA. Here, the boundary region is a partial region included in the display area DA, and may be a partial region positioned further outside than the sensor electrode SE4 disposed at the outermost side among the sensor electrodes SE_TX extending in the first direction. Figure 3 and Figure 4In the example, the boundary area may include a first boundary area and a second boundary area, the first boundary area is positioned further outside than the sensor electrode SE4 set at the outermost side in the left direction (the direction opposite to the second direction) among the sensor electrodes SE_TX extending in the first direction, and the second boundary area is positioned further outside than the sensor electrode set at the outermost side in the right direction (the second direction) among the sensor electrodes SE_TX extending in the first direction. Figure 5 is another plan view illustrating a touch sensor included in the display panel 110 according to an embodiment of the present disclosure.

[0144] Reference Figure 5 In the touch sensor included in the display panel 110 according to an embodiment of the present disclosure, among the multiple contact holes CNT connecting the multiple receiving sensor electrodes SE_RX and the multiple receiving traces TL_RX, some of the contact holes CNT may be positioned at the outer side of the outermost transmitting trace TL_TX among the multiple transmitting traces TL_TX, and other contact holes CNT may be positioned at the inner side compared with the outermost transmitting trace TL_TX or TL4 among the multiple transmitting traces TL_TX and some transmitting sensor electrodes SE_TX (for example, the fourth sensor electrode SE4 set at the outermost side).

[0145] For example, the reception traces TL_RX respectively corresponding to different reception sensor electrodes SE_RX may be disposed in such a manner that the transmission sensor electrode SE_TX (eg, the fourth sensor electrode SE4 ) is interposed therebetween.

[0146] exist Figure 3 , Figure 4 and Figure 5 In the touch sensor, each of the plurality of transmitting sensor electrodes SE_TX may be arranged to extend in a first direction (eg, a column direction), and each of the plurality of receiving sensor electrodes SE_RX may be arranged to extend in a second direction (eg, a row direction).

[0147] Figure 6 is another plan view illustrating a touch sensor included in the display panel 110 according to an embodiment of the present disclosure.

[0148] Reference Figure 6 In the touch sensor included in the display panel 110 according to an embodiment of the present disclosure, each of the plurality of transmitting sensor electrodes SE_TX may be configured to extend in a second direction (e.g., a row direction), and each of the plurality of receiving sensor electrodes SE_RX may be configured to extend in a first direction (e.g., a column direction).

[0149] exist Figures 3 to 7 As an example, the plurality of sensor electrodes SE arranged to extend in the second direction may include first, second, third, and fifth sensor electrodes SE1, SE2, SE3, and SE5, and the plurality of sensor electrodes SE arranged to extend in the first direction include fourth sensor electrodes SE4.

[0150] For example, in Figure 3 , Figure 4 , Figure 5 and Figure 7 , the plurality of reception sensor electrodes SE_RX extending in the second direction include the first sensor electrode SE1 , the second sensor electrode SE2 , the third sensor electrode SE3 , and the fifth sensor electrode SE5 , and the plurality of transmission sensor electrodes SE_TX extending in the first direction include the fourth sensor electrode SE4 .

[0151] As another example, in Figure 6 , the plurality of transmission sensor electrodes SE_TX extending in the second direction include the first sensor electrode SE1 , the second sensor electrode SE2 , the third sensor electrode SE3 , and the fifth sensor electrode SE5 , and the plurality of reception sensor electrodes SE_RX extending in the first direction include the fourth sensor electrode SE4 .

[0152] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, at least one first trace TL1 may be electrically connected to two opposite ends of the first sensor electrode SE1 provided to extend in the second direction. In other words, one or two or more first traces TL1 may be electrically connected to one end of the two opposite ends of the first sensor electrode SE1, and one or two or more first traces TL1 may be electrically connected to the other end of the two opposite ends of the first sensor electrode SE1. In this case, the signal transmission delay at the first sensor electrode SE1 itself extended in the second direction may be reduced.

[0153] Likewise, at least one second trace TL2 may be electrically connected to two opposite ends of the second sensor electrode SE2 arranged to extend in the second direction. At least one third trace TL3 may be electrically connected to two opposite ends of the third sensor electrode SE3 arranged to extend in the second direction. At least one fifth trace TL5 may be electrically connected to two opposite ends of the fifth sensor electrode SE5 arranged to extend in the second direction.

[0154] Alternatively, at least one first trace TL1 may be electrically connected to only one of two opposite ends of the first sensor electrode SE1 arranged to extend in the second direction. At least one second trace TL2 may be electrically connected to only one of two opposite ends of the second sensor electrode SE2 arranged to extend in the second direction. At least one third trace TL3 may be electrically connected to only one of two opposite ends of the third sensor electrode SE3 arranged to extend in the second direction. At least one fifth trace TL5 may be electrically connected to only one of two opposite ends of the fifth sensor electrode SE5 arranged to extend in the second direction.

[0155] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, two first traces TL1 connected to two opposite ends of the first sensor electrode SE1 may be electrically connected to two first pads PD1. Two second traces TL2 connected to two opposite ends of the second sensor electrode SE2 may be electrically connected to two second pads PD2. Two third traces TL3 connected to two opposite ends of the third sensor electrode SE3 may be electrically connected to two third pads PD3. Two fifth traces TL5 connected to two opposite ends of the fifth sensor electrode SE5 may be electrically connected to two fifth pads PD5.

[0156] Figure 7 is another plan view illustrating a touch sensor included in the display panel 110 according to an embodiment of the present disclosure.

[0157] Reference Figure 7 , two first traces TL1 may be electrically connected to two opposite ends of the first sensor electrode SE1 disposed to extend in the second direction. In other words, one first trace TL1 may be electrically connected to one of the two opposite ends of the first sensor electrode SE1, and one first trace TL1 may be electrically connected to the other of the two opposite ends of the first sensor electrode SE1. In this case, when the first sensor electrode SE1 is longer in the second direction, the signal transmission delay at the first sensor electrode SE1 itself may be reduced.

[0158] Likewise, the two second traces TL2 may be electrically connected to two opposite ends of the second sensor electrode SE2 arranged to extend in the second direction. The two third traces TL3 may be electrically connected to two opposite ends of the third sensor electrode SE3 arranged to extend in the second direction. The two fifth traces TL5 may be electrically connected to two opposite ends of the fifth sensor electrode SE5 arranged to extend in the second direction.

[0159] As described above, by connecting two traces TL to one sensor electrode SE, a signal transmission delay occurring in the sensor electrode SE itself can be reduced.

[0160] Reference Figure 7 , two first traces TL1 connected to two opposite ends of the first sensor electrode SE1 may be commonly connected to one first pad PD1. Two second traces TL2 connected to two opposite ends of the second sensor electrode SE2 may be commonly connected to one second pad PD2. Two third traces TL3 connected to two opposite ends of the third sensor electrode SE3 may be commonly connected to one third pad PD3. Two fifth traces TL5 connected to two opposite ends of the fifth sensor electrode SE5 may be commonly connected to one fifth pad PD5.

[0161] According to the pad sharing structure, one pad can be connected to two traces TL connected to two opposite ends of one sensor electrode SE. Therefore, the number of pads in the display panel 110 can be reduced and the size of the pad area PA can be reduced, and the number of pads (the number of channels) of the touch drive circuit 160 connected to the pad area PA can be reduced. Therefore, the size of the touch drive circuit 160 can also be reduced.

[0162] Reference Figures 3 to 7 , a plurality of transmission pads PD_TX and a plurality of reception pads PD_RX provided in the pad area PA may be arranged to be clustered for each type. In other words, a plurality of transmission pads PD_TX may be arranged together, and a plurality of reception pads PD_RX may be arranged together.

[0163] Alternatively, a plurality of transmission pads PD_TX and a plurality of reception pads PD_RX disposed in the pad area PA may be mixed and disposed.

[0164] Reference Figure 3 , Figure 4 and Figure 6 , in the first non-display area NDA1, the plurality of transmission traces TL_TX and the plurality of reception traces TL_RX may not cross each other. In this case, the plurality of transmission traces TL_TX and the plurality of reception traces TL_RX may not overlap in the vertical direction. Therefore, the plurality of transmission traces TL_TX and the plurality of reception traces TL_RX may be provided in different metal layers, or may be provided in the same metal layer.

[0165] Reference Figure 5 and Figure 7, in the first non-display area NDA1, all or some of the plurality of receiving traces TL_RX may cross all or some of the plurality of transmitting traces TL_TX. In this case, the plurality of transmitting traces TL_TX and the plurality of receiving traces TL_RX may overlap in the vertical direction. Therefore, the plurality of transmitting traces TL_TX and the plurality of receiving traces TL_RX should be arranged in different metal layers.

[0166] Reference Figures 3 to 7 , the substrate 111 may include: a display area DA provided with a plurality of sub-pixels SP, and a non-display area NDA including a pad area PA located in a first direction relative to the display area DA.

For example, the first direction may be a column direction (Y-axis direction), and the second direction crossing the first direction may be a row direction (X-axis direction).

[0169] Reference Figures 3 to 7 , the plurality of pads PD may include a first pad PD1 disposed in the pad area PA and a second pad PD2 disposed in the pad area PA.

[0170] Reference Figures 3 to 7 , the plurality of traces TL may include a first trace TL1 electrically connecting the first sensor electrode SE1 and the first pad PD1 , and a second trace TL2 electrically connecting the second sensor electrode SE2 and the second pad PD2 .

[0171] Reference Figures 3 to 7 , the second sensor electrode SE2 may be positioned closer to the pad area PA than the first sensor electrode SE1. The first trace TL1 may overlap the second sensor electrode SE2.

[0172] Reference Figures 3 to 7 , the first trace TL1 and the second trace TL2 may extend across the display area DA to the pad area PA in the first direction.

[0173] Reference Figures 3 to 7 The multiple sensor electrodes SE may further include a third sensor electrode SE3 disposed in the display area DA and extending in the second direction, the multiple pads PD may further include a third pad PD3 disposed in the pad area PA, and the multiple traces TL may further include a third trace TL3 electrically connecting the third sensor electrode SE3 and the third pad PD3.

[0174] The third sensor electrode SE3 may be positioned closer to the pad area PA than the second sensor electrode SE2 .

[0175] Each of the first trace TL1 and the second trace TL2 may overlap the third sensor electrode SE3 .

[0176] Reference Figures 3 to 7 The multiple sensor electrodes SE may also include a fourth sensor electrode SE4 arranged in the display area DA and extending in the first direction, and a fifth sensor electrode SE5 arranged in the display area DA and extending in the second direction, the multiple pads PD may also include a fourth pad PD4 arranged in the pad area PA and a fifth pad PD5 arranged in the pad area PA, and the multiple traces TL may include a fourth trace TL4 for electrically connecting the fourth sensor electrode SE4 and the fourth pad PD4, and a fifth trace TL5 for electrically connecting the fifth sensor electrode SE5 and the fifth pad PD5.

[0177] The fourth sensor electrode SE4 may be positioned closer to the pad area PA than the first and second sensor electrodes SE1 and SE2 .

[0178] Each of the first trace TL1 , the second trace TL2 , and the third trace TL3 may overlap the fifth sensor electrode SE5 .

[0179] Reference Figure 3 , Figure 4 , Figure 5 and Figure 7 Among the first sensor electrode SE1, the second sensor electrode SE2, the third sensor electrode SE3, the fourth sensor electrode SE4 and the fifth sensor electrode SE5, the fourth sensor electrode SE4 may be a transmitting sensor electrode, and the first sensor electrode SE1, the second sensor electrode SE2, the third sensor electrode SE3 and the fifth sensor electrode SE5 may be a receiving sensor electrode.

[0180] Therefore, a signal (touch drive signal) whose voltage level is changed may be supplied from the touch drive circuit 160 to the fourth sensor electrode SE4 .

[0181] Reference Figure 6 Among the first sensor electrode SE1, the second sensor electrode SE2, the third sensor electrode SE3, the fourth sensor electrode SE4 and the fifth sensor electrode SE5, the fourth sensor electrode SE4 may be a receiving sensor electrode, and the first sensor electrode SE1, the second sensor electrode SE2, the third sensor electrode SE3 and the fifth sensor electrode SE5 may be a sending sensor electrode.

[0182] A signal (touch drive signal) whose voltage level is changed from the touch drive circuit 160 may be supplied to each of the first to second to third and fifth sensor electrodes SE1 to SE2 and SE3 and SE5 .

[0183] Reference Figure 4 , the number of first traces TL1 connected to the first sensor electrode SE1 may be greater than the number of fifth traces TL5 connected to the fifth sensor electrode SE5. For example, the number of first traces TL1 connected to the first sensor electrode SE1 may be twice the number of fifth traces TL5 connected to the fifth sensor electrode SE5. Figure 4 As shown, the number of first traces TL1 connected to the first sensor electrode SE1 may be four, and the number of fifth traces TL5 connected to the fifth sensor electrode SE5 may be two. As another example, the number of first traces TL1 connected to the first sensor electrode SE1 may be two, and the number of fifth traces TL5 connected to the fifth sensor electrode SE5 may be one.

[0184] Reference Figures 3 to 7 , the fourth sensor electrode SE4 may cross the first sensor electrode SE1 , the second sensor electrode SE2 , and the fifth sensor electrode SE5 .

[0185] Reference Figure 3 , Figure 4 , Figure 6 and Figure 7 , the first trace TL1 , the second trace TL2 , the third trace TL3 , and the fifth trace TL5 may all be disposed outside the fourth sensor electrode SE4 .

In this case, the fourth sensor electrode SE4 may be disposed between the first trace TL1 and the fifth trace TL5. Alternatively, the fourth sensor electrode SE4 may be disposed between the first trace TL1 and the contact hole CNT of the first sensor electrode SE1 and the fifth trace TL5 and the contact hole CNT of the fifth sensor electrode SE5.

[0187] Reference Figures 3 to 7 , a plurality of transmission pads PD_TX and a plurality of reception pads PD_RX provided in the pad area PA may be arranged to be clustered for each type. In other words, a plurality of transmission pads PD_TX may be arranged together, and a plurality of reception pads PD_RX may be arranged together.

[0188] Alternatively, a plurality of transmission pads PD_TX and a plurality of reception pads PD_RX disposed in the pad area PA may be mixed and disposed.

[0189] Reference Figure 5 , when a plurality of transmission pads PD_TX and a plurality of reception pads PD_RX disposed in the pad area PA are provided to be clustered for each type, the fifth pad PD5 may be disposed between the first pad PD1 and the fourth pad PD4.

[0190] In this case, the fifth trace TL5 may cross the fourth trace TL4. Therefore, the fifth trace TL5 should be positioned in a different metal layer from the fourth trace TL4. For example, the fifth trace TL5 may include a bridge metal, and the fourth trace TL4 may include a sensor metal.

[0191] When a plurality of transmission pads PD_TX and a plurality of reception pads PD_RX provided in the pad area PA are set to be mixed, Figure 5 Differently, the fourth pad PD4 may be disposed between the first pad PD1 and the fifth pad PD5 .

[0192] The fifth trace TL5 may not cross the fourth trace TL4. Therefore, the fifth trace TL5 may be positioned in the same metal layer as the fourth trace TL4. For example, the fifth trace TL5 and the fourth trace TL4 may include a bridge metal or a sensor metal.

[0193] Hereinafter, for the convenience of description, the plurality of sensor electrodes SE arranged to extend in the first direction are the transmission sensor electrodes SE_TX, and the plurality of sensor electrodes SE arranged to extend in the second direction are the reception sensor electrodes SE_RX.

[0265] In contrast, the first sensor electrode SE1 , the second sensor electrode SE2 , and the third sensor electrode SE3 may be the transmission sensor electrodes SE_TX, and the fourth sensor electrode SE4 may be the reception sensor electrode SE_RX.

[0266] according to Fig.11 In the trace structure, each trace TL may be disposed from the pad area PA to the contact hole CNT electrically connected to the corresponding sensor electrode SE. Therefore, each trace TL may overlap at least one sensor electrode SE located on a path where it is disposed.

[0267] Reference Fig.11 , the first trace TL1 may be provided from the pad area PA to the first contact hole CNT1 electrically connected to the first sensor electrode SE1. Therefore, the first trace TL1 may overlap not only the first sensor electrode SE1 electrically connected to the first trace TL1, but also the second sensor electrode SE2 and the third sensor electrode SE3 which are not electrically connected to the first trace TL1.

[0268] Reference Fig.11 , the second trace TL2 may be provided from the pad area PA to the second contact hole CNT2 electrically connected to the second sensor electrode SE2. Therefore, the second trace TL2 may overlap not only the second sensor electrode SE2 electrically connected to the second trace TL2, but also the third sensor electrode SE3 not electrically connected to the second trace TL2.

[0269] Reference Fig.11 , the third trace TL3 may be provided from the pad area PA to the third contact hole CNT3 electrically connected to the third sensor electrode SE3. Therefore, the third trace TL3 may overlap not only the third sensor electrode SE3 electrically connected to the third trace TL3 but also another sensor electrode SE not electrically connected to the third trace TL3.

[0270] Fig.12 The trace structure of is the parasitic capacitance equivalent design structure of each trace TL. Fig.12 In the trace structure, each trace TL may be arranged to extend from the pad area PA across the display area DA to the opposite end of the pad area PA, and may be electrically connected to the corresponding sensor electrode SE in the corresponding contact hole CNT. Therefore, each trace TL may overlap all the plurality of sensor electrodes SE located on the path where it is arranged.

[0271] Reference Fig.12 , the first trace TL1 may be disposed to extend from the pad area PA across the display area DA to the opposite end of the pad area PA, and may be electrically connected to the first sensor electrode SE1 in the first contact hole CNT1. Therefore, the first trace TL1 may overlap not only the first sensor electrode SE1 electrically connected to the first trace TL1, but also the second sensor electrode SE2 and the third sensor electrode SE3 which are not electrically connected to the first trace TL1.

[0272] Reference Fig.12 , the second trace TL2 may be provided to extend from the pad area PA across the display area DA to the opposite end of the pad area PA, and may be electrically connected to the second sensor electrode SE2 in the second contact hole CNT2. Therefore, the second trace TL2 may overlap not only the second sensor electrode SE2 electrically connected to the second trace TL2, but also the first sensor electrode SE1 and the third sensor electrode SE3 which are not electrically connected to the second trace TL2. Here, the first sensor electrode SE1 may be the sensor electrode SE located between the opposite end of the pad area PA and the second contact hole CNT2.

[0273] Reference Fig.12 , the third trace TL3 may be provided to extend from the pad area PA across the display area DA to the opposite end of the pad area PA, and may be electrically connected to the third sensor electrode SE3 in the third contact hole CNT3. Therefore, the third trace TL3 may overlap not only the third sensor electrode SE3 electrically connected to the third trace TL3, but also the first sensor electrode SE1 and the second sensor electrode SE2 which are not electrically connected to the third trace TL3. Here, the first sensor electrode SE1 and the second sensor electrode SE2 may be the sensor electrodes SE located between the opposite end of the pad area PA and the third contact hole CNT3.

[0274] according to Fig.12 The trace structure can reduce the parasitic capacitance deviation caused by each of the first trace TL1, the second trace TL2 and the third trace TL3.

[0275] Fig.13 The trace structure of is a design structure equivalent to the load value of each trace TL. Here, the load value may refer to a resistance-capacitance (RC) value obtained by multiplying resistance and capacitance.

[0276] according to Fig.13 In the trace structure, each trace TL may be disposed from the pad area PA to the contact hole CNT electrically connected to the corresponding sensor electrode SE. Therefore, each trace TL may overlap at least one sensor electrode SE located on a path where it is disposed.

[0277] Reference Fig.13 , the first trace TL1 may be provided from the pad area PA to the first contact hole CNT1 across the display area DA, and electrically connected to the first sensor electrode SE1. Therefore, the first trace TL1 may overlap not only the first sensor electrode SE1 electrically connected to the first trace TL1, but also the second sensor electrode SE2 and the third sensor electrode SE3 which are not electrically connected to the first trace TL1.

[0278] Reference Fig.13 , the second trace TL2 may be provided from the pad area PA across the display area DA to the second contact hole CNT2 to be electrically connected to the second sensor electrode SE2. Therefore, the second trace TL2 may overlap not only the second sensor electrode SE2 electrically connected to the second trace TL2, but also the third sensor electrode SE3 not electrically connected to the second trace TL2, and may not overlap the first sensor electrode SE1.

[0279] Reference Fig.13 , the third trace TL3 may be provided from the pad area PA across the display area DA to the third contact hole CNT3 to be electrically connected to the third sensor electrode SE3. Therefore, the third trace TL3 may overlap not only the third sensor electrode SE3 electrically connected to the third trace TL3 but also another sensor electrode SE not electrically connected to the third trace TL3, but may not overlap the first sensor electrode SE1 and the second sensor electrode SE2.

[0280] Reference Fig.13 , the second trace TL2 may include a first meander portion MP1. At least a portion of the first meander portion MP1 may overlap with a region occupied by the second sensor electrode SE2.

[0281] For example, the first meandering portion MP1 present in the second trace TL2 may be a meandering line portion in the second trace TL2, a bending line portion in the second trace TL2, or a twisting line portion in the second trace TL2, and may also be referred to as a bent portion or a bent portion. That is, the first meandering portion MP1 includes a plurality of portions, each of which extends in the display area DA along one of the first direction, the second direction, or a third direction different from the first direction and the second direction.

[0282] Therefore, as the length of the second trace TL2 is compensated, the deviation between the load value of the second trace TL2 and the load value of the first trace TL1 may be reduced.Through the first meandering portion MP1 of the second trace TL2, the second sensor electrode SE2 may have a load value corresponding to that of the first sensor electrode SE1.

[0283] For example, when the capacitance (parasitic capacitance) between the second trace TL2 and the peripheral electrode (e.g., SE3) is the same as the capacitance (parasitic capacitance) between the first trace TL1 and the peripheral electrode (e.g., SE2 and SE3), if the resistance of the second trace TL2 is the same as (e.g., substantially matched with) the resistance of the first trace TL1, the load value of the second trace TL2 and the load value of the first trace TL1 may be the same. According to the wiring design for compensating the resistance of the second trace TL2 to be the same as the resistance of the first trace TL1, the total length of the second trace TL2 in the display area DA may be the same as or similar to the total length of the first trace TL1 through the meandering portion MP1.

[0284] As another example, Fig.13 As shown, when the first contact hole CNT1 is farther away from the pad area PA than the second contact hole CNT2, the capacitance (parasitic capacitance) between the second trace TL2 and the peripheral electrode (e.g., SE3) may be smaller than the capacitance (parasitic capacitance) between the first trace TL1 and the peripheral electrode (e.g., SE2 and SE3). In this case, when the resistance of the second trace TL2 becomes greater than the resistance of the first trace TL1, the load value of the second trace TL2 and the load value of the first trace TL1 may be the same or substantially the same. According to the design for making the resistance of the second trace TL2 greater than the resistance of the first trace TL1, the total length of the second trace TL2 in the display area DA may be greater than the total length of the first trace TL1 through the meandering portion MP1.

[0285] Reference Fig.13 , the first trace TL1 may not include a meander portion. Alternatively, the first trace TL1 may include a meander portion. When the first trace TL1 includes a meander portion, the length of the meander portion when the meander portion of the first trace TL1 is straightened may be shorter than the length of the first meander portion MP1 of the second trace TL2 when the meander portion MP1 is straightened.

[0286] Reference Fig.13 , the third trace TL3 may include a second meandering portion MP2. The second meandering portion MP2 may be disposed in a region occupied by the third sensor electrode SE3.

[0287] For example, the second meandering portion MP2 present in the third trace TL3 may be a meandering line portion in the third trace TL3 , a bending line portion in the third trace TL3 , or a twisting line portion in the third trace TL3 .

[0288] The third sensor electrode SE3 may be positioned closer to the pad area PA than the second sensor electrode SE2. Considering this, the length of the second meander portion MP2 of the third trace TL3 when it is straightened may be greater than the length of the first meander portion MP1 of the second trace TL2 when it is straightened.

[0289] Reference Fig.13 , the first meandering portion MP1 of the second trace TL2 may overlap with the fourth sensor electrode SE4. The second meandering portion MP2 of the third trace TL3 may overlap with the fourth sensor electrode SE4.

[0298] The display panel 110 according to an embodiment of the present disclosure may include: a substrate 111, which includes a display area DA provided with a plurality of sub-pixels SP and a non-display area NDA including a pad area PA positioned in a first direction relative to the display area DA; a light emitting element ED, which is disposed on the substrate 111 in the display area DA; an encapsulation layer 200, which is disposed on the light emitting element ED; a first sensor electrode SE1, which is located in the display area DA and is disposed on the encapsulation layer 200; a second sensor electrode SE2, which is located in the display area DA and is disposed on the encapsulation layer 200; a first pad PD1, which is disposed in the pad area PA; a second pad PD2, which is disposed in the pad area PA; a first trace TL1, which electrically connects the first sensor electrode SE1 and the first pad PD1 and extends across the display area DA to the pad area PA in the first direction; and a second trace TL2, which electrically connects the second sensor electrode SE2 and the second pad PD2 and extends across the display area DA to the pad area PA in the first direction.

[0299] Reference Fig.15 The non-display area NDA may include a first non-display area NDA1 (e.g., a first portion) positioned in a first direction relative to the display area DA, a second non-display area NDA2 (e.g., a second portion) positioned in a second direction relative to the display area DA, a third non-display area NDA3 (e.g., a third portion) positioned in a direction opposite to the first direction relative to the display area DA, and a fourth non-display area NDA4 (e.g., a fourth portion) positioned in a direction opposite to the second direction relative to the display area DA.

[0300] Reference Fig.15 , the encapsulation layer 200 may be disposed in the display area DA, and may extend to a partial area of ​​the non-display area NDA.

[0301] Reference Fig.15, the encapsulation layer 200 may include a first inclined surface SLP1 positioned outside in a first direction relative to the center, a second inclined surface SLP2 positioned outside in a second direction intersecting the first direction relative to the center, a third inclined surface SLP3 positioned outside in a direction opposite to the first direction relative to the center, and a fourth inclined surface SLP4 positioned outside in a direction opposite to the second direction relative to the center. The term "center" in the embodiments refers to, for example, the center of a display panel, a substrate, or a display area. That is, the encapsulation layer 200 includes: a first inclined surface SLP1 at a first portion (e.g., NDA1) of the non-display area, the first inclined surface SLP1 being adjacent to a first side of the display area DA extending in the second direction; a second inclined surface SLP2 at a second portion NDA2 of the non-display area, the inclined surface SLP2 being adjacent to a second side of the display area DA extending in the first direction; a third inclined surface SLP3 at a third portion NDA3 of the non-display area, the third inclined surface SLP3 being adjacent to a third side of the display area extending in the second direction and being spaced apart from the first side of the display area DA in the first direction; and a fourth inclined surface SLP4 at a fourth portion NDA4 of the non-display area, the fourth inclined surface SLP4 being adjacent to a fourth side of the display area DA extending in the first direction and being spaced apart from the second side of the display area DA in the second direction.

[0302] The first, second, third, and fourth inclined surfaces SLP1, SLP2, SLP3, and SLP4 of the encapsulation layer 200 may be located in the non-display area NDA. That is, the traces (eg, TL1, TL2, etc.) overlap the first inclined surface SLP1 but not the remaining inclined surfaces SLP2 to SLP4.

[0303] In the first inclined surface SLP1, the second inclined surface SLP2, the third inclined surface SLP3 and the fourth inclined surface SLP4 of the encapsulation layer 200, metal (e.g., traces) may not be set on the second inclined surface SLP2 and the fourth inclined surface SLP4, and the trace TL including the first trace TL1 that is set to extend in the first direction may pass through the first inclined surface SLP1.

[0304] For example, in Figure 3 , Figure 4 and Figure 5 In the case of the touch sensor, the traces extending in the first direction (including the first trace TL1 on the first slope SLP1) may be the receiving traces TL_RX.

[0305] As another example, in Figure 6In the case of the touch sensor, the traces extending in the first direction (including the first traces TL1 on the first inclined surface SLP1) may be the transmission traces TL_TX.

[0306] Reference Fig.15 , the first non-display area NDA1 may include a pad area PA. For example, the pad area PA may include a pad to which the driving circuit is electrically connected, or may include a pad to which a circuit film or a printed circuit board on which the driving circuit is mounted is electrically connected. For example, the driving circuit may include a touch driving circuit 160. The driving circuit may also include a data driving circuit 120.

[0307] For example, when the driving circuit is a chip on glass (COG) type, the pad area PA may include pads to which the driving circuit is electrically connected. As another example, when the driving circuit is a chip on film (COF) type, the pad area PA may include pads to which a circuit film (also called a flexible printed circuit (FPC)) on which the driving circuit is mounted is electrically connected.

[0308] Reference Fig.15 , the first non-display area NDA1 may further include a bending area BA. In this case, the substrate 111 may be a flexible substrate. In some cases, the first non-display area NDA1 may not include the bending area BA.

[0309] Fig.16 , Fig.17 and Fig.18 is a cross-sectional view showing main points of the display panel 110 according to an embodiment of the present disclosure. However, Figures 16 to 18 An example is shown in which the bending area BA is included in the first non-display area NDA1.

[0310] Fig.16 and Fig.17 is a cross-sectional view showing a region including the first non-display area NDA1 and a portion of the display area DA adjacent thereto. Fig.16 Shows Figure 3 FIG. 4 is a vertical cross-sectional structure of a path in which the fourth sensor electrode SE4 and the fourth pad PD4 are connected by the fourth trace TL4. Fig.17 Shows Figure 3 FIG. 5 is a vertical cross-sectional structure of a path in which the fifth sensor electrode SE5 and the fifth pad PD5 are connected by the fifth trace TL5 .

[0311] Fig.18 is a cross-sectional view showing a region including the second non-display area NDA2 or the fourth non-display area NDA4 and a portion of the display area DA adjacent thereto. Fig.18 A vertical cross-sectional structure of a region where the first sensor electrode SE1 and the first trace TL1 are connected is shown.

[0312] Reference Fig.16 The substrate 111 may include a display area DA and a first non-display area NDA1, the first non-display area NDA1 being an outer area of ​​the display area DA in the first direction, and the first non-display area NDA1 may include a bending area BA and a pad area PA.

[0313] A first transistor T1 may be disposed on a substrate 111. The first transistor T1 may include a first electrode E1, a second electrode E2, a third electrode E3, and an active layer ACT. The second electrode E2 may be a gate electrode, the first electrode E1 may be a source electrode or a drain electrode, and the third electrode E3 may be a drain electrode or a source electrode.

[0314] For example, when the first transistor T1 has a coplanar structure, an active layer ACT may be provided on the substrate 111, a gate insulating film 1610 may be provided on the active layer ACT, and a second electrode E2 corresponding to the gate electrode may be provided on the gate insulating film 1610. An interlayer insulating film 1630 may be provided on the second electrode E2. A first electrode E1 and a third electrode E3 may be provided on the interlayer insulating film 1630. The first electrode E1 may be connected to a portion of the active layer ACT through a contact hole of the interlayer insulating film 1630. The third electrode E3 may be connected to another portion of the active layer ACT through another contact hole of the interlayer insulating film 1630.

[0315] A planarization film 1650 may be disposed on the first transistor T1 .

[0316] A pixel electrode PE may be disposed on the planarization film 1650. The pixel electrode PE may be connected to the first electrode E1 of the first transistor T1 through a contact hole of the planarization film 1650.

[0317] A bank 1660 may be disposed on the pixel electrode PE. The bank 1660 may have an opening in a region where a light emitting region of the light emitting element ED of the sub-pixel SP should be formed.

[0318] An element intermediate layer EL may be disposed on the bank 1660. A portion of the element intermediate layer EL may be connected to a portion of the upper surface of the pixel electrode PE through the opening of the bank 1660.

[0319] A common electrode CE may be provided on the element intermediate layer EL.

[0320] An encapsulation layer 200 may be disposed on the common electrode CE. The encapsulation layer 200 may be a single film or a multi-layer film.

[0321] For example, when the encapsulation layer 200 includes a plurality of films, the encapsulation layer 200 may have a structure in which inorganic films and organic films are alternately stacked. For example, the encapsulation layer 200 may include a first encapsulation layer 1671, a second encapsulation layer 1672, a third encapsulation layer 1673, etc., and the first encapsulation layer 1671 and the third encapsulation layer 1673 may be inorganic films, and the second encapsulation layer 1672 may be an organic film. The second encapsulation layer 1672 may be thicker than the first encapsulation layer 1671 and the third encapsulation layer 1673.

[0322] The encapsulation layer 200 may extend from the display area DA to a partial area of ​​the first non-display area NDA1.

[0323] The first encapsulation layer 1671 may be disposed on the common electrode CE, and the first encapsulation layer 1671 may be disposed to cover the common electrode CE. The first encapsulation layer 1671 may cover the common electrode CE and extend to the first non-display area NDA1 to cover at least one dam D1 and D2. The first encapsulation layer 1671 may extend to the pad area PA disposed outside the at least one dam D1 and D2 to overlap with the pad PD4.

[0324] The second encapsulation layer 1672 may be disposed on the first encapsulation layer 1671. The second encapsulation layer 1672 may be formed to have a sufficient thickness to prevent foreign matter (particles) from penetrating into the element intermediate layer EL and the common electrode CE including an organic material through the first encapsulation layer 1671. The second encapsulation layer 1672 may be formed through a curing process after being applied in a liquid form through an inkjet process.

[0325] The third encapsulation layer 1673 may be disposed on the second encapsulation layer 1672. The third encapsulation layer 1673 may be disposed to cover the second encapsulation layer 1672. The third encapsulation layer 1673 may cover the second encapsulation layer 1672, and may extend to the first non-display area NDA1 to cover at least one dam D1 and D2. In addition, the third encapsulation layer 1673 may extend to the pad area PA disposed outside the at least one dam D1 and D2 to overlap with the pad PD4. In this case, the first encapsulation layer 1671 and the third encapsulation layer 1673 may be formed to have the same end position.

[0326] For example, each of the first encapsulation layer 1671 and the third encapsulation layer 1673 may be formed of silicon nitride, aluminum nitride, zirconium nitride, titanium nitride, hafnium nitride, tantalum nitride, silicon oxide, aluminum oxide, or titanium oxide.

[0327] For example, the second encapsulation layer 1672 may be formed of acrylic resin, epoxy resin, phenolic resin, polyamide resin, or polyimide resin.

[0328] A touch sensor may be formed on the encapsulation layer 200. The touch sensor forming layer on the encapsulation layer 200 may include a touch buffer film 1010 ( Fig.16 ), a bridge metal layer BML, a touch interlayer insulating film 1020 , a sensor metal layer SML and a touch protection film 1030 .

[0329] In order to form a touch sensor, the touch buffer film 1010 may be disposed on the encapsulation layer 200, such as Fig. 10A and 10B As shown, the touch buffer film 1010 can be omitted on the encapsulation layer 200, as shown in FIG. Fig.16 shown.

[0330] The metal layer directly above the touch buffer film 1010 and the encapsulation layer 200 may be a bridge metal layer BML. The insulating film directly above the bridge metal layer BML may be a touch interlayer insulating film 1020. The metal layer directly above the touch interlayer insulating film 1020 may be a sensor metal layer SML.

[0331] according to Fig.16 For example, a fifth bridge BRG5 formed of a bridge metal BM may be disposed on the encapsulation layer 200. A touch interlayer insulating film 1020 may be disposed on the fifth bridge BRG5. A fourth sensor electrode SE4 formed of a sensor metal SM may be disposed on the touch interlayer insulating film 1020.

[0332] Reference Fig.16 , a portion of the fourth sensor electrode SE4 extending to the first non-display area NDA1 may be a fourth trace line TL4. Therefore, the fourth trace line TL4 may be formed of the sensor metal SM.

[0333] The fourth trace TL4 may descend along the first inclined surface SLP1 of the encapsulation layer 200 and extend to the pad area PA of the first non-display area NDA1 .

[0334] The touch protection film 1030 may be disposed on the sensor electrodes SE including the fourth sensor electrode SE4 and the fifth sensor electrode SE5. The touch protection film 1030 may protect the touch sensor by blocking harmful environments from the outside and stabilize the characteristics of the display device 100. For example, the touch protection film 1030 may be an organic film. The touch protection film 1030 may be disposed to extend to the non-display area NDA.

[0335] The display panel 110 may have a dam area DAM disposed in the non-display area NDA and disposed to surround the display area DA. At least one dam D1 or D2 may be disposed in the dam area DAM.

[0336] At least one dam D1 or D2 may be included in the encapsulation layer 200 and may block the flow of the second encapsulation layer 1672, which may be an organic film. In other words, at least one dam D1 or D2 may prevent the second encapsulation layer 1672, which may be an organic film, from collapsing. Therefore, at least one dam D1 or D2 may prevent the second encapsulation layer 1672, which is an organic film, from being exposed to the outside of the display device 100 or intruding into the pad area PA.

[0337] At least one dam D1 and D2 may be provided.

[0338] The first dam D1 may be disposed near an outer point of the second encapsulation layer 1672 included in the encapsulation layer 200. The first dam D1 may be disposed to surround the periphery of the display area DA to mainly block the flow of the second encapsulation layer 1672. In addition, the first dam D1 may be disposed between the display area DA and the pad area PA to mainly block the flow of the second encapsulation layer 1672, thereby preventing the second encapsulation layer 1672 from intruding into the pad area PA.

[0339] The second dam D2 may be disposed around the periphery of the first dam D1 and may be disposed side by side to be spaced apart from the first dam D1. The second dam D2 may secondarily block the second encapsulation layer 1672 from flowing toward the periphery of the first dam D1. Therefore, the first dam D1 and the second dam D2 may more effectively block the second encapsulation layer 1672 from being exposed to the outside of the display device 100 or intruding into the pad area PA.

[0340] At least one dam D1 or D2 may be formed simultaneously with the planarization film 1650 or the bank 1660 and may be formed of the same material as the planarization film 1650 or the bank 1660. In this case, at least one dam D1 or D2 may be formed of an organic material such as acrylic resin, epoxy resin, phenolic resin, polyamide resin, polyimide resin, etc.

[0341] The fourth trace TL4 may be formed to extend from the top of the encapsulation layer 200 to the upper portion of at least one dam D1 and D2, and may be electrically connected to the first connection pattern 1640a disposed thereunder through a touch contact hole TCT, which is a contact hole of the touch interlayer insulating film 1020. Therefore, the fourth trace TL4 may not be disposed in the bending area BA.

[0342] The fourth trace TL4 may be electrically connected to the fourth pad PD4 in the pad area PA through the first connection pattern 1640a, the second connection pattern 1620a, and the third connection pattern 1641a. Here, the touch driving circuit 160 may be directly or indirectly connected to the fourth pad PD4.

[0343] The first connection pattern 1640a and the third connection pattern 1641a may include the same material as the source-drain electrodes of the first transistor T1. The second connection pattern 1620a may include the same material as the gate electrode or the gate line GL of the first transistor T1.

[0344] A bending film 1651 may be disposed on a portion of the third connection pattern 1641 a , and a pattern protection film 1652 may be disposed on another portion of the third connection pattern 1641 a .

[0345] The bending film 1651 may be disposed in the bending area BA, may be disposed between the dams D1 and D2 and the pad PD4, and may be disposed to cover the upper portion of a portion of the third connection pattern 1641a. The bending film 1651 may prevent and protect the third connection pattern 1641a from being exposed to the outside in the bending area BA where the substrate 111 is bent. In addition, the bending film 1651 may be provided with an opening OH through which the upper portion of the bending film is exposed. In other words, the opening OH may be formed by removing an inorganic film (e.g., a first encapsulation layer 1671, a third encapsulation layer 1673, and a touch interlayer insulating film 1020) that may be disposed on the bending film 1651. When the inorganic film is disposed on the bending film 1651, cracks may occur in the inorganic film when the bending area BA is bent, and moisture, etc. may penetrate into the inorganic film in which cracks occur. Therefore, the inorganic film disposed on the bending film 1651 is removed.

[0346] The pattern protection film 1652 may be disposed to surround an end portion of the third connection pattern 1641a. The pattern protection film 1652 may protect an end portion of the third connection pattern 1641a disposed at an edge of the first non-display area NDA1.

[0347] The bending film 1651 and the pattern protection film 1652 may be disposed on the same layer as the planarization film 1650 and may be formed of the same material.

[0348] For example, the planarization film 1650 , the bending film 1651 , and the pattern protection film 1652 may be formed of an organic film such as acrylic resin, epoxy resin, phenolic resin, polyamide resin, polyimide resin, or the like.

[0349] In the pad area PA, the fourth pad PD4 may be electrically connected to the third connection pattern 1641 a through a pad contact hole PCT penetrating the first encapsulation layer 1671 , the third encapsulation layer 1673 , and the touch interlayer insulating film 1020 .

[0350] In the following, reference is made to Fig.17 A vertical cross-sectional structure of a path in which the fifth sensor electrode SE5 and the fifth pad PD5 are connected by the fifth trace TL5 is described. The following description mainly focuses on the differences, and the differences related to the fifth sensor electrode SE5 and the fifth pad PD5 are omitted from the description. Fig.16 The vertical section structure has the same content.

[0351] Reference Fig.17 , the fifth sensor electrode SE5 disposed in the display area DA may include a fifth bridge BRG5 electrically connecting the plurality of fifth sub sensor electrodes SUB5a and SUB5b and the plurality of fifth sub sensor electrodes SUB5a and SUB5b.

[0352] The fifth bridge BRG5 may overlap the fourth sensor electrode SE4 .

[0353] The plurality of fifth sub sensor electrodes SUB5a and SUB5b included in the fourth and fifth sensor electrodes SE4 and SE5 may be disposed in the sensor metal layer SML. In other words, the plurality of fifth sub sensor electrodes SUB5a and SUB5b included in the fourth and fifth sensor electrodes SE4 and SE5 may include the sensor metal SM.

[0354] The fifth bridge BRG5 may be disposed in the bridge metal layer BML. In other words, the fifth bridge BRG5 may be formed of the bridge metal BM.

[0355] A fifth trace TL5 electrically connected to one (eg, SUB5a) of the plurality of fifth sub sensor electrodes SUB5a and SUB5b included in the fifth sensor electrode SE5 may be disposed in the bridge metal layer BML. In other words, the fifth trace TL5 may be formed of the bridge metal BM.

[0356] The fifth trace TL5 may descend along the first inclined surface SLP1 of the encapsulation layer 200 and extend to the pad area PA.

[0357] The fifth trace TL5 may be formed to extend from the top of the encapsulation layer 200 to the upper portion of at least one dam D1 and D2, and may be electrically connected to the fourth connection pattern 1640b disposed thereunder through a touch contact hole TCT, which is a contact hole of the touch interlayer insulating film 1020. Therefore, the fifth trace TL5 may not be disposed in the bending area BA.

[0358] The fifth trace TL5 may be electrically connected to the fifth pad PD5 in the pad area PA through the fourth connection pattern 1640b, the fifth connection pattern 1620b, and the sixth connection pattern 1641b. Here, the touch driving circuit 160 may be directly or indirectly connected to the fifth pad PD5.

[0359] The fourth connection pattern 1640b and the sixth connection pattern 1641b may include the same material as the source-drain electrodes of the first transistor T1. The fifth connection pattern 1620b may include the same material as the gate electrode or the gate line GL of the first transistor T1.

[0360] Reference Fig.17 , the touch protection film 1030 may be disposed on the sensor electrodes SE including the fourth sensor electrode SE4 and the fifth sensor electrode SE5. The touch protection film 1030 may protect the touch sensor and stabilize the characteristics of the display device 100 by blocking harmful environments from the outside. In addition, the touch protection film 1030 may be disposed between the transmitting sensor electrode (e.g., the fourth sensor electrode SE4) and the receiving sensor electrode (e.g., the fifth sensor electrode SE5) and on the sensor electrode SE including the fourth sensor electrode SE4 and the fifth sensor electrode SE5. Therefore, the transmitting sensor electrode (e.g., the fourth sensor electrode SE4) may be insulated from the receiving sensor electrode (e.g., the fifth sensor electrode SE5) by the touch protection film 1030.

[0361] Refer to the following Fig.18 The vertical structure of the region including the second non-display area NDA2 and the fourth non-display area NDA4 and a portion of the display area DA adjacent thereto is described. For this purpose, the vertical cross-sectional structure of the region where the first sensor electrode SE1 and the first trace TL1 are connected is described as an example. The following description mainly focuses on the differences, and the differences with the first sensor electrode SE1 and the first trace TL1 are omitted from the description. Fig.16 The vertical section structure has the same content.

[0362] Reference Fig.18 , the second non-display area NDA2 and the fourth non-display area NDA4 may not include the bending area BA and the pad area PA. Therefore, the sizes of the second non-display area NDA2 and the fourth non-display area NDA4 may be reduced.

[0363] Furthermore, according to an embodiment of the present disclosure, the trace TL is not provided in the second non-display area NDA2 and the fourth non-display area NDA4 of the display panel 110. Therefore, an extremely narrow bezel structure of the display panel 110 may be possible.

[0364] Reference Fig.18 , the first sensor electrode SE1 disposed in the display area DA may include a plurality of first sub sensor electrodes SUB1a and SUB1b and a first bridge BRG1 electrically connecting the plurality of first sub sensor electrodes SUB1a and SUB1b.

[0365] The first bridge BRG1 may overlap the fourth sensor electrode SE4 .

[0366] The fourth sensor electrode SE4 and the plurality of first sub sensor electrodes SUB1a and SUB1b included in the first sensor electrode SE1 may be disposed in the sensor metal layer SML. In other words, the fourth sensor electrode SE4 and the plurality of first sub sensor electrodes SUB1a and SUB1b included in the first sensor electrode SE1 may include the sensor metal SM.

[0367] The first bridge BRG1 may be disposed in the bridge metal layer BML. In other words, the first bridge BRG1 may be formed of the bridge metal BM.

[0368] A first trace TL1 electrically connected to one (eg, SUB1a) of the plurality of first sub sensor electrodes SUB1a and SUB1b included in the first sensor electrode SE1 may be disposed in the bridge metal layer BML. In other words, the first trace TL1 may be formed of the bridge metal BM.

[0369] The first trace TL1 may extend to the first non-display area NDA1 across the display area DA without bypassing the second and fourth non-display areas NDA2 and NDA4 , and may be connected to the first pad P1 in the pad area PA included in the first non-display area NDA1 .

[0370] Therefore, the first trace TL1 may not be disposed on the second and fourth inclined surfaces SLP2 and SLP4 of the encapsulation layer 200 , but may be disposed along the first inclined surface SLP1 of the encapsulation layer 200 to extend to the pad area PA.

[0371] Reference Fig.18 , when the first trace TL1 crosses the display area DA without bypassing the second non-display area NDA2 and the fourth non-display area NDA4, the first trace TL1 may be disposed to avoid the emission area EA of each of the plurality of sub-pixels SP in the display area DA. In other words, the first trace TL1 may overlap the bank 1660 without overlapping the emission area EA of each of the plurality of sub-pixels SP. Therefore, the internal trace structure may be designed without deteriorating the light emitting performance.

[0372] Reference Fig.18 , the first sensor electrode SE1 electrically connected to the first trace TL1 and the first trace TL1 may not overlap the emission area EA of each of the plurality of sub-pixels SP but may overlap the bank 1660 .

[0373] The following briefly describes the above-mentioned embodiments of the present disclosure.
