[0041] Hereinafter, various embodiments of the present disclosure are described in detail with reference to the accompanying drawings.
[0042] Figure 1 is a system configuration diagram of the display device 100 according to an embodiment of the present disclosure.
[0043] 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.
[0044] The display panel 110 may include a substrate 111 and a plurality of sub-pixels SP disposed on the substrate 111 .
[0045] The substrate 111 of the display panel 110 may include a display area DA capable of displaying an image and a non-display area NDA located outside the display area DA.
[0046] A plurality of sub-pixels SP for image display may be provided in the display area DA, and the non-display area NDA may include a pad area PA located in a first direction with respect to the display area DA.
[0047] In the display panel 110 according to an embodiment of the present disclosure, the non-display area NDA may be very small. In this specification, the non-display area NDA may also be referred to as a "bezel."
[0048] For example, the non-display area NDA may include a first non-display area located outside the display area DA in a first direction, a second non-display area located outside the display area DA in a second direction intersecting the first direction, a third non-display area located outside the display area DA in a direction opposite to the first direction, and a fourth non-display area located outside the display area DA in a direction opposite to the second direction. One or two of the first to fourth non-display areas may include a pad area to which the data driving circuit 120 is connected or bonded. Among the first to fourth non-display areas, two or three non-display areas excluding the pad area may be very small in size.
[0049] For another example, the boundary area between the display area DA and the non-display area NDA may be bent so that the non-display area NDA is located below the display area. In this case, when a user views the display device 100 from the front, little or no non-display area NDA may be visible to the user.
[0050] Various types of signal lines for driving the plurality of sub-pixels SP may be provided on the substrate 111 of the display panel 110 .
[0051] The display device 100 according to an embodiment of the present disclosure may be a liquid crystal display device or the like, or may be a self-luminous display device in which the display panel 110 emits light itself. 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 device.
[0052] For example, the display device 100 according to an embodiment of the present disclosure may be an organic light-emitting display device in which the light-emitting device is implemented as an organic light-emitting diode (OLED). For 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 device is implemented as an inorganic-based light-emitting diode. For 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 device is implemented using quantum dots, which are semiconductor crystals that emit light themselves.
[0053] The structure of each of the plurality of sub-pixels SP may vary depending on the type of the display device 100. For example, if the display device 100 is a self-luminous display device in which the sub-pixels SP emit light themselves, each sub-pixel SP may include a self-luminous light emitting device, one or more transistors, and one or more capacitors.
[0054] For example, the various types of signal lines may include a plurality of data lines DL supplying data signals (also referred to as data voltages or image signals) and a plurality of gate lines GL for transmitting gate signals (also referred to as scan signals).
[0055] For example, a plurality of data lines DL and a plurality of gate lines GL may intersect 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. Alternatively, the first direction may be a row direction, and the second direction may be a column direction. Hereinafter, for ease of explanation, a case will be exemplified in which 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.
[0056] 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 receive image data in a digital form from the display controller 140 and convert the received image data into analog data signals to output to the plurality of data lines DL.
[0058] For example, the data driving circuit 120 can be connected to the display panel 110 using a tape automated bonding (TAB) method, or can be connected to the bonding pads of the display panel 110 using a chip on glass (COG) or chip on panel (COP) method, or can be implemented and connected to the display panel 110 using a chip on film (COF) method.
[0059] The data driving circuit 120 may be connected to one side (e.g., the upper side or the lower side) of the display panel 110. Depending on a driving method, a panel design method, etc., the data driving circuit 120 may be connected to both sides (e.g., the upper side and the lower side) of the display panel 110, or may be connected to two or more of the four sides of the display panel 110.
[0060] The data driving circuit 120 may be connected to the outside of the display area DA of the display panel 110 , but alternatively, the data driving circuit 120 may be provided in the display area DA of the display panel 110 .
[0061] 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.
[0062] The gate driving circuit 130 may receive a first gate voltage corresponding to an on-level voltage and a second gate voltage corresponding to an off-level voltage and various gate driving control signals GCS, and may generate and supply gate signals to a plurality of gate lines GL.
[0063] In the display device 100 according to an embodiment of the present disclosure, the gate driving circuit 130 may be built into the display panel 110 as a gate-in-panel (GIP) type. If the gate driving circuit 130 is a gate-in-panel type, the gate driving circuit 130 may be formed on a substrate of the display panel 110 during a manufacturing process of the display panel 110.
[0064] In the display device 100 according to an embodiment of the present disclosure, the gate driver circuit 130 may be provided in the display area DA of the display panel 110. For example, the gate driver circuit 130 may be provided in a first partial area (e.g., the left area or the right area) within the display area DA. For another example, the gate driver circuit 130 may be provided in both the first partial area (e.g., the left area or the right area) and the second partial area (e.g., the right area or the left area) within the display area DA.
[0065] In the present disclosure, the gate driving circuit 130 built into the display panel 110 as an in-panel gate type may be referred to as an “in-panel gate circuit”.
[0066] The display controller 140 may be 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.
[0067] The display controller 140 may supply a data driving control signal DCS to the data driving circuit 120 to control the data driving circuit 120 , and may supply a gate driving control signal GCS to the gate driving circuit 130 to control the gate driving circuit 130 .
[0068] The display controller 140 may receive input image data from the host system 150 and supply image data DATA to the data driving circuit 120 based on the input image data.
[0069] The display controller 140 may be implemented as a separate component from the data driving circuit 120 , or may be integrated with the data driving circuit 120 and implemented as an integrated circuit.
[0070] The display controller 140 may be a timing controller used in typical display technologies, or may be a control device capable of further performing other control functions including a timing controller, or may be a control device different from a timing controller, or may be a control device other than a timing controller, or may be a circuit within a control device. The display controller 140 may be implemented using 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.
[0071] The display controller 140 may be mounted on a printed circuit board, a flexible printed circuit, or the like, and may be electrically connected to the data driving circuit 120 and the gate driving circuit 130 through the printed circuit board, the flexible printed circuit, or the like.
[0072] The display controller 140 may transmit and receive signals with the data driving circuit 120 according to one or more predetermined interfaces. For example, the interface may include a low voltage differential signaling (LVDS) interface, an embedded clock point-to-point interface (EPI) interface, or a serial peripheral interface (SPI).
[0073] In order to provide not only an image display function but also a touch sensing function, the display device 100 according to an embodiment of the present disclosure may include: a touch sensor; and a touch sensing circuit for detecting the occurrence of a touch of a touch object such as a finger or a pen or detecting a touch position by sensing the touch sensor.
[0074] The touch sensing circuit may include a touch driving circuit for driving and sensing the touch sensor to generate and output touch sensing data, and a touch controller for detecting occurrence of a touch or detecting a touch position using the touch sensing data.
[0075] The touch sensor may include a plurality of touch electrodes and a plurality of touch lines to electrically connect the plurality of touch electrodes and the touch driving circuit.
[0076] The touch sensor may be present in the form of a touch panel outside the display panel 110, or may be present inside the display panel 110. If the touch sensor is present in the form of a touch panel outside the display panel 110, the touch sensor may be referred to as an external type. If the touch sensor is an external type, the touch panel and the display panel 110 may be manufactured separately and combined during the assembly process. The external touch panel may include a touch panel substrate and a plurality of touch electrodes on the touch panel substrate.
[0077] If the touch sensor exists inside the display panel 110 , the touch sensor may be formed on a substrate together with signal lines and electrodes related to display driving during a manufacturing process of the display panel 110 .
[0078] The touch driving circuit may supply a touch driving signal to at least one of the plurality of touch electrodes and generate touch sensing data by sensing at least one of the plurality of touch electrodes.
[0079] The touch sensing circuit may perform touch sensing using a self-capacitance sensing method or a mutual capacitance sensing method.
[0080] If the touch sensing circuit performs touch sensing using a self-capacitance sensing method, the touch sensing circuit can perform touch sensing based on the capacitance between each touch electrode and a touch object (e.g., a finger, a pen, etc.). According to the self-capacitance sensing method, each of the multiple touch electrodes can function as a driving touch electrode and a sensing touch electrode. The touch drive circuit can drive all or part of the multiple touch electrodes and sense all or part of the multiple touch electrodes.
[0081] If the touch sensing circuit uses a mutual capacitance sensing method to perform touch sensing, the touch sensing circuit can perform touch sensing based on the capacitance between touch electrodes. According to the mutual capacitance sensing method, the multiple touch electrodes can be divided into drive touch electrodes and sense touch electrodes. The touch drive circuit can drive the drive touch electrodes and sense the sense touch electrodes.
[0082] The touch driving circuit and the touch controller included in the touch sensing circuit may be implemented as separate devices or one device. In addition, the touch driving circuit and the data driving circuit may be implemented as separate devices or one device.
[0083] The display device 100 may further include a power supply circuit that supplies various types of power to the display driving circuit and / or the touch sensing circuit.
[0084] The display device 100 according to an embodiment of the present disclosure may be a mobile terminal such as a smartphone or a tablet, or monitors or televisions of various sizes, but is not limited thereto, and may be displays of various types and sizes capable of displaying information or images.
[0085] The display device 100 according to an embodiment of the present disclosure may further include an electronic device, such as a camera (e.g., an image sensor) and a detection sensor. For example, the detection sensor may be a sensor for detecting an object or a human body by receiving light such as infrared, ultrasonic, or ultraviolet rays.
[0086] At the same time, the light emitted by the display panel 110 may be emitted from the display panel 110 at a predetermined viewing angle. When each of the plurality of sub-pixels SP emits light, a frame image may be displayed on the display panel 110. If light is emitted from one sub-pixel SP, the light may be emitted at a predetermined angle. For example, each of the plurality of sub-pixels SP may emit light at a predetermined viewing angle range, such as 30 degrees, 60 degrees, 120 degrees, or 150 degrees. In the case where the viewing angle is n degrees (n is a natural number greater than or equal to 1), based on the front face from which light is emitted, the left side may be n / 2 degrees, and the right side may be n / 2 degrees. If the viewing angle is relatively large, it may be referred to as a "wide angle" or a "wide viewing angle." In addition, if the viewing angle is relatively small, it may be referred to as a "narrow angle" or a "narrow viewing angle."
[0087] The viewing angle of the display panel 110 may be fixed. Alternatively, the viewing angle of the display panel 110 may be variable. For example, the viewing angle of the display panel 110 may be controlled by a light control film (LCF), a lens layer, or other viewing angle control structures.
[0088] As an example of a method for controlling the viewing angle of the display panel 110, one subpixel SP may include two light-emitting devices. The two light-emitting devices may be a first light-emitting device and a second light-emitting device. The first light-emitting device may be a light-emitting device for narrow-angle driving, and the second light-emitting device may be a light-emitting device for wide-angle driving. Since the first light-emitting device and the second light-emitting device are selectively driven, a frame image can be displayed on the display panel 110 at a narrow angle or a wide angle.
[0089] Figure 2 A display panel 110 according to an embodiment of the present disclosure is shown.
[0090] Reference Figure 2 , the display panel 110 may include a substrate 111 disposed in the plurality of sub-pixels SP and an encapsulation layer 200 on the substrate 111. Here, the encapsulation layer 200 may also be referred to as an encapsulation substrate or an encapsulation portion.
[0091] 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 device ED and a sub-pixel circuit SPC for driving the light emitting device ED.
[0092] Reference Figure 2 The sub-pixel circuit SPC may include a plurality of pixel driving transistors and at least one capacitor for driving the light-emitting device ED. In the present disclosure, the sub-pixel circuit SPC may drive the light-emitting device ED by supplying a driving current to the light-emitting device ED at a predetermined timing. The light-emitting device ED may be driven by the driving current and emit light.
[0093] The plurality of pixel driving transistors may include a driving transistor DT for driving the light emitting device ED and a scan transistor ST that is turned on or off according to a scan signal SC.
[0094] The driving transistor DT may supply a driving current to the light emitting device ED.
[0095] The scan transistor ST may be configured to control an electrical state of a corresponding node in the sub-pixel circuit SPC, or to control a state or operation of the drive transistor DT.
[0096] The at least one capacitor may include a storage capacitor Cst to maintain a constant voltage during a frame.
[0097] 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.
[0098] The light emitting device ED may include an anode AND, a light emitting device intermediate layer EL, and a cathode CAT. The light emitting device intermediate layer EL may be a layer disposed between the anode AND and the cathode CAT.
[0099] When the light-emitting device ED is an organic light-emitting device, the light-emitting device intermediate layer EL may include a light-emitting layer EML, a first common intermediate layer COM1 between the anode AND and the light-emitting layer EML, and a second common intermediate layer COM2 between the light-emitting layer EML and the cathode. The light-emitting layer EML may be provided in each sub-pixel SP. In contrast, the first common intermediate layer COM1 and the second common intermediate layer COM2 may be provided in common across multiple sub-pixels SP. The light-emitting layer EML may be provided in each light-emitting region, and the first common intermediate layer COM1 and the second common intermediate layer COM2 may be provided in common across multiple light-emitting regions and non-light-emitting regions. The first common intermediate layer COM1 and the second common intermediate layer COM2 may be collectively referred to as the common intermediate layer EL_COM.
[0100] For example, the first common intermediate layer COM1 may include a hole injection layer HIL and a hole transport layer HTL. The second common intermediate layer COM2 may include an electron transport layer ETL and an electron injection layer EIL. The hole injection layer may inject holes from the anode AND into the hole transport layer, and the hole transport layer may transport holes to the light-emitting layer EML. The electron injection layer may inject electrons from the cathode CAT into the electron transport layer, and the electron transport layer may transport electrons to the light-emitting layer EML.
[0101] For example, the cathode CAT may be electrically connected to a second common driving voltage line VSSL. A second common driving voltage VSS, which is a common pixel driving voltage, may be applied to the cathode CAT via the second common driving voltage line VSSL. The anode AND may be electrically connected to the first node N1 of the driving transistor DT of each sub-pixel SP. In the present disclosure, the second common driving voltage VSS may also be referred to as a base voltage VSS, and the second common driving voltage line VSSL may also be referred to as a base voltage line VSSL.
[0102] For example, the anode AND may be a pixel electrode provided in each sub-pixel SP, and the cathode CAT may be a common electrode provided in common in the plurality of sub-pixels SP. For another example, the cathode CAT may be a pixel electrode provided in each sub-pixel SP, and the anode AND may be a common electrode provided in common in the plurality of sub-pixels SP. Hereinafter, for ease of explanation, it is assumed that the anode AND is a pixel electrode, and the cathode CAT is a common electrode.
[0103] Each light-emitting device ED may be composed of an overlapping portion of an anode AND, a light-emitting device intermediate layer EL, and a cathode CAT. Each light-emitting device ED may form a predetermined light-emitting region. For example, the light-emitting region of each light-emitting device ED may include a region where the anode AND, the light-emitting device intermediate layer EL, and the cathode CAT overlap.
[0104] For example, the light emitting device ED may be an organic light emitting diode (OLED), an inorganic light emitting diode, or a quantum dot light emitting device. For example, when the light emitting device ED is an organic light emitting diode OLED, the light emitting device intermediate layer EL in the light emitting device ED may include an organic light emitting device intermediate layer EL containing an organic material.
[0105] The driving transistor DT may be a driving transistor for supplying a driving current to the light emitting device ED. The driving transistor DT may be connected between the first common driving voltage line VDDL and the light emitting device ED.
[0106] The driving transistor DT may include a first node N1 electrically connected to the light emitting device ED, a second node N2 to which the data signal VDATA is applied, and a third node N3 to which the driving voltage VDD is applied from the driving voltage line VDDL.
[0107] In the driving transistor DT, the second node N2 may be a gate node, the first node N1 may be a source node or a drain node, and the third node N3 may be a drain node or a source node. Hereinafter, for ease of explanation, a case in which the second node N2 is a gate node, the first node N1 is a source node, and the third node N3 is a drain node in the driving transistor DT will be described.
[0108] Figure 2 The scan transistor ST included in the illustrated sub-pixel circuit SPC 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 driving transistor DT.
[0109] The scanning transistor ST can be turned on and off by a scanning signal SC (the scanning signal SC is a gate signal applied through the scanning line SCL as a gate line GL), and can control the electrical connection between the second node N2 of the driving transistor DT and the data line DL. The drain electrode or the source electrode of the scanning transistor ST can be electrically connected to the data line DL, and the source electrode or the drain electrode of the scanning transistor ST can be electrically connected to the second node N2 of the driving transistor DT. The gate electrode of the scanning transistor ST can be electrically connected to the scanning line SCL.
[0110] The storage capacitor Cst may be electrically connected between the first node N1 and the second node N2 of the driving transistor DT. The storage capacitor Cst may include a first capacitor electrode electrically connected to or corresponding to the first node N1 of the driving transistor DT, and a second capacitor electrode electrically connected to or corresponding to the second node N2 of the driving transistor DT.
[0111] The storage capacitor Cst may be an external capacitor intentionally designed outside the driving transistor DT, rather than a parasitic capacitor (eg, Cgs, Cgd) that is an internal capacitor that may exist between the first node N1 and the second node N2 of the driving transistor DT.
[0112] Each of the driving transistor DT and the scanning transistor ST may be an n-type transistor or a p-type transistor.
[0113] The display panel 110 may have a top emission structure or a bottom emission structure.
[0114] If the display panel 110 has a top emission structure, at least a portion of the sub-pixel circuit SPC may overlap at least a portion of the light-emitting device ED in the vertical direction. Alternatively, if the display panel 110 has a bottom emission structure, the sub-pixel circuit SPC may not overlap with the light-emitting device ED in the vertical direction.
[0115] like Figure 2 As shown, the sub-pixel circuit SPC may have a 2T-1C structure including two transistors T1 and T2 and one capacitor Cst. In some cases, the sub-pixel circuit SPC may further include one or more transistors or one or more capacitors.
[0116] For example, the sub-pixel circuit SPC may have an 8T-1C structure including eight transistors and a single capacitor. For another example, the sub-pixel circuit SPC may have a 6T-2C structure including six transistors and two capacitors. For another example, the sub-pixel circuit SPC may have a 7T-1C structure including seven transistors and one capacitor.
[0117] According to the structure of the sub-pixel circuit SPC, the type and number of gate signals and / or gate lines supplied to the sub-pixels SP may be changed.
[0118] In addition, the type and number of common pixel driving voltages supplied to the sub-pixels SP may be changed according to the structure of the sub-pixel circuit SPC.
[0119] Since the circuit elements within each sub-pixel SP (particularly, the light-emitting device ED implemented using an organic light-emitting diode (OLED) containing organic materials) are susceptible to external moisture or oxygen, an encapsulation layer 200 may be provided on the display panel 110 to prevent oxygen from penetrating into the circuit elements (particularly, the light-emitting device ED). The encapsulation layer 200 may be configured in various shapes to prevent the light-emitting device ED from contacting moisture or oxygen.
[0120] Reference Figure 2 The display device 100 according to an embodiment of the present disclosure may further include: a touch sensor layer TSL, which includes a plurality of sensor electrodes to sense a user's touch; and a touch sensing circuit 210, which is configured to sense the plurality of sensor electrodes to determine whether there is a touch or touch coordinates.
[0121] The touch sensor layer TSL may be built-in or embedded in the display panel 110. For example, the touch sensor layer TSL may be provided on the encapsulation layer 200 within the display panel 110.
[0122] The display panel 110 may include not only a touch sensor layer TSL, but also a plurality of touch pads TP to which the touch sensing circuit 210 is electrically connected; and a plurality of touch wirings TL for electrically connecting the plurality of sensor electrodes included in the touch sensor layer TSL and the plurality of touch pads connected to the touch sensing circuit 210.
[0123] Reference Figure 2 , a plurality of touch electrodes TE may be provided on the touch sensor layer TSL. The plurality of touch electrodes TE may have a rhombus shape, a rhombus shape, or a square shape, but the plurality of touch electrodes TE may also have various shapes, such as a triangle, a pentagon, or a hexagon.
[0124] Reference Figure 2, the touch electrode TE may be a plate-shaped touch sensor metal TSM without an opening. In this case, the touch electrode TE may be a transparent electrode. The touch electrode TE may include a transparent electrode material so that light emitted from a plurality of sub-pixels SP disposed below the touch electrode TE can be transmitted upward.
[0125] Figure 3 Various embodiments of the touch electrode TE according to the embodiment of the present disclosure are shown.
[0126] and Figure 2 The touch electrodes TE shown are different. Figure 3 The touch electrode TE shown may include an opening area OA, a dummy metal DM, or a dummy area DMA.
[0127] Reference Figure 3 , shows the first example (case 1). Figure 3 , the touch electrode TE may be in a grid shape. The touch electrode TE may be formed of a touch sensor metal TSM patterned into a grid type to form a plurality of opening areas OA. The touch sensor metal TSM of the touch electrode TE may be a portion corresponding to the actual touch electrode TE, and may be a portion to which a touch drive signal is applied or a portion to which a touch sensing signal is detected. The touch sensor metal TSM corresponding to the touch electrode TE may be located on a bank (not shown) provided in an area other than the light emitting area EA of the sub-pixel SP. The opening area OA may correspond to the light emitting area of the sub-pixel SP, or may correspond to a transmissive area.
[0128] Reference Figure 3 , showing a second example (case 2). The touch electrode TE may include a mesh-type touch sensor metal TSM and one or more dummy metals DM spaced apart from the touch sensor metal TSM. The dummy metal DM may be located in an area surrounded by the touch sensor metal TSM within the area of the touch electrode TE. Unlike the touch sensor metal TSM, the dummy metal DM may be a metal that does not receive touch drive signals and does not transmit touch sensing signals. The touch sensor metal TSM may be electrically connected to a touch drive circuit, but the dummy metal DM may not be electrically connected to the touch drive circuit. If the touch electrode TE does not include the dummy metal DM but only includes the touch sensor metal TSM, a visibility problem may occur in which the outline of the touch sensor metal TSM is visible on the screen. If the dummy metal DM is provided, the visibility problem in which the outline of the touch sensor metal TSM is visible on the screen can be prevented.
[0129] Reference Figure 3 , showing a third example (case 3). The touch electrode TE may be formed by removing a portion of the inner region of the touch electrode TE. Figure 3 The touch electrode TE may include a dummy area DMA in which a portion of the touch sensor metal TSM is removed. The dummy area DMA may have a rhombus shape, but is not limited thereto. The touch sensor metal TSM may be disposed in an outer area of the dummy area DMA and may be disposed in a grid-like grid type.

[0131] Reference Figure 4 The substrate SUB may include a first substrate SUB1, an interlayer insulating film IPD, and a second substrate SUB2. The interlayer insulating film IPD may be located between the first substrate SUB1 and the second substrate SUB2.

[0137] The first gate electrode GATE of the drive transistor DRT may be provided on the gate insulating film GI. In this case, the gate material layer GM may be provided on the gate insulating film GI together with the first gate electrode GATE of the drive transistor DRT at a position different from the formation position of the drive transistor DRT.
[0138] A first interlayer insulating film ILD1 may be provided while covering the first gate electrode GATE and the gate material layer GM. A metal pattern TM may be provided on the first interlayer insulating film ILD1. The metal pattern TM may be located at a position different from the formation position of the drive transistor DRT. A second interlayer insulating film ILD2 may be provided on the first interlayer insulating film ILD1 while covering the metal pattern TM.
[0139] Two first source-drain electrode patterns SD1 may be provided on the second interlayer insulating film ILD2. One of the two first source-drain electrode patterns SD1 may be a source node of the drive transistor DRT, and the other may be a drain node of the drive transistor DRT. The two first source-drain electrode patterns SD1 may be electrically connected to one side and the other side of the active layer ACT through contact holes formed through the second interlayer insulating film ILD2, the first interlayer insulating film ILD1, and the gate insulating film GI.
[0140] A portion of the active layer ACT overlapping the first gate electrode GATE may be a channel region. One of the two first source-drain electrode patterns SD1 may be connected to one side of the channel region in the active layer ACT, and the other of the two first source-drain electrode patterns SD1 may be connected to the other side of the channel region in the active layer ACT.
[0141] A passivation layer PAS0 may be provided to cover the two first source-drain electrode patterns SD1 , and a planarization layer PLN may be provided on the passivation layer PAS0 . The planarization layer PLN may include a first planarization layer PLN1 and a second planarization layer PLN2 .
[0142] A first planarization layer PLN1 may be disposed on the passivation layer PAS0 .
[0143] A second source-drain electrode pattern SD2 may be provided on the first planarization layer PLN1. The second source-drain electrode pattern SD2 may be connected to one of the two first source-drain electrode patterns SD1 (corresponding to the first source-drain electrode pattern SD2) through a contact hole of the first planarization layer PLN1. Figure 2 a second node N2 of the driving transistor DRT in the sub-pixel SP).
[0144] A second planarization layer PLN2 may be provided while covering the second source-drain electrode pattern SD2. A light emitting device ED may be provided on the second planarization layer PLN2.
[0145] In the stacked structure of the light emitting device ED, an anode electrode AE may be disposed on the second planarization layer PLN2 and electrically connected to the second source-drain electrode pattern SD2 through a contact hole of the second planarization layer PLN2.
[0146] The bank BANK may be provided to cover a portion of the anode electrode AE, and a portion of the bank BANK corresponding to the emission area EA of the sub-pixel SP may be opened.
[0147] A portion of the anode electrode AE may be exposed to an opening (eg, an opening portion) of the bank BANK. The light emitting layer EL may be located on one side of the bank BANK and in the opening (eg, an opening portion) of the bank BANK. All or part of the light emitting layer EL may be located between adjacent banks BANK.
[0148] In the opening of the bank BANK, the light emitting layer EL may be in contact with the anode electrode AE, and a cathode electrode CE may be provided on the light emitting layer EL.
[0149] The light emitting device ED may be formed of an anode electrode AE, a light emitting layer EL, and a cathode electrode CE. The light emitting layer EL may include an organic film.
[0150] An encapsulation layer ENCAP may be disposed on the light emitting device ED.
[0151] The encapsulation layer ENCAP may have a single-layer structure or a multi-layer structure. Figure 4 As shown, the encapsulation layer ENCAP may include a first inorganic encapsulation layer PAS1 , an organic encapsulation layer PCL, and a second inorganic encapsulation layer PAS2 .
[0152] For example, the first and second inorganic encapsulation layers PAS1 and PAS2 may be inorganic films, and the organic encapsulation layer PCL may be an organic film. Among the first, organic, and second inorganic encapsulation layers PAS1, PAS2, the organic encapsulation layer PCL may be the thickest and may serve as a planarization layer.
[0153] The first inorganic encapsulation layer PAS1 may be disposed on the cathode electrode CE and may be disposed closest to the light emitting device ED. The first inorganic encapsulation layer PAS1 may be formed of an inorganic insulating material capable of low temperature deposition. For example, the first inorganic encapsulation layer PAS1 may include silicon nitride (SiN x ), silicon oxide (SiO x), silicon oxynitride (SiON), aluminum oxide (Al2O3), etc. Since the first inorganic encapsulation layer PAS1 is deposited in a low temperature atmosphere, the first inorganic encapsulation layer PAS1 can prevent the light emitting layer EL including an organic material susceptible to a high temperature atmosphere from being damaged during the deposition process.
[0154] The organic encapsulation layer PCL may be formed with an area smaller than the first inorganic encapsulation layer PAS1. In this case, the organic encapsulation layer PCL may be formed so that both ends of the first inorganic encapsulation layer PAS1 are exposed. The organic encapsulation layer PCL may act as a buffer to alleviate the stress between the layers caused by the bending of the display device 100, and may also be used to enhance the planarization performance. For example, the organic encapsulation layer PCL may be made of acrylic resin, epoxy resin, polyimide, polyethylene, or silicon oxycarbon SiOC, and may be formed of an organic insulating material. For example, the organic encapsulation layer PCL may be formed by an inkjet process.
[0155] A second inorganic encapsulation layer PAS2 may be formed on the substrate SUB on which the organic encapsulation layer PCL is formed to cover the upper surface and side surfaces of each of the organic encapsulation layer PCL and the first inorganic encapsulation layer PAS1. The second inorganic encapsulation layer PAS2 may minimize or block external moisture or oxygen from penetrating into the first inorganic encapsulation layer PAS1 and the organic encapsulation layer PCL. For example, the second inorganic encapsulation layer PAS2 may be made of a material such as silicon nitride (SiN x ), silicon oxide (SiO x ), silicon oxynitride (SiON) or aluminum oxide (Al2O3) inorganic insulating materials.
[0156] Reference Figure 4 If the touch sensor TS is a type built into the display panel 110, the touch sensor TS may be disposed on the encapsulation layer ENCAP. The touch sensor structure will be described in detail below.
[0157] A touch buffer film T-BUF may be provided on the encapsulation layer ENCAP, and a touch sensor TS may be provided on the touch buffer film T-BUF.
[0158] The touch sensor TS may include a touch sensor metal TSM and a bridge metal BRG located in different layers.
[0159] A touch interlayer insulating film T-ILD may be disposed between the touch sensor metal TSM and the bridge metal BRG.
[0160] For example, the touch sensor metal TSM may include a first touch sensor metal TSM, a second touch sensor metal TSM, and a third touch sensor metal TSM disposed adjacent to each other. If the third touch sensor metal TSM is located between the first touch sensor metal TSM and the second touch sensor metal TSM and the first touch sensor metal TSM and the second touch sensor metal TSM need to be electrically connected to each other, the first touch sensor metal TSM and the second touch sensor metal TSM may be electrically connected to each other via a bridge metal BRG located in different layers. The bridge metal BRG may be insulated from the third touch sensor metal TSM by a touch interlayer insulating film T-ILD.
[0161] When the touch sensor TS is formed on the display panel 110, chemical solutions (e.g., developer solution or etchant) used in the process or moisture from the outside may be generated. Since the touch sensor TS is provided on the touch buffer film T-BUF, the chemical solution or moisture can be prevented from penetrating into the light-emitting layer EL, which includes an organic material, during the manufacturing process of the touch sensor TS. Therefore, the touch buffer film T-BUF can prevent damage to the light-emitting layer EL, which is susceptible to chemical solutions or moisture.
[0162] The touch buffer film T-BUF can be formed under low temperature conditions below a specific temperature (e.g., 100 degrees (°C)), and can be formed of an organic insulating material with a low dielectric constant of 1 to 3 to prevent damage to the light-emitting layer EL containing organic materials that are susceptible to high temperatures. For example, the touch buffer film T-BUF can be formed of an acrylic series, an epoxy series, or a siloxane series material. As the display device 100 is bent, the encapsulation layer ENCAP may be damaged, and the touch sensor metal located on the touch buffer film T-BUF may be broken or disconnected. Even if the display device 100 is bent, the touch buffer film T-BUF made of an organic insulating material with flattening properties can prevent damage to the encapsulation layer ENCAP and / or damage to the metal TSM or BRG forming the touch sensor TS.
[0163] Reference Figure 4 , a protection layer PAC may be provided while covering the touch sensor TS. The protection layer PAC may be an organic insulating film.
[0164] The display device according to the embodiment of the present invention can sense touch using a mutual capacitance-based touch sensing method, or can sense touch using a self-capacitance-based touch sensing method. However, hereinafter, for ease of explanation, a display device that performs mutual capacitance-based touch sensing and has a touch sensor structure for such touch sensing will be described as an example.
[0165] Figure 5A configuration of touch sensing according to an embodiment of the present disclosure is shown.
[0166] Reference Figure 5 The touch sensor structure for mutual capacitance-based touch sensing may include a plurality of first touch electrode lines TEL1 and a plurality of second touch electrode lines TEL2. Here, the plurality of first touch electrode lines TEL1 and the plurality of second touch electrode lines TEL2 may be located on the encapsulation layer ENCAP.

Each of the plurality of second touch electrode lines TEL2 may include a plurality of second touch electrodes TE2 electrically connected to each other. The plurality of first touch electrodes TE1 and the plurality of second touch electrodes TE2 may be included in the plurality of touch electrodes (TE). The plurality of first touch electrodes TE1 constituting each of the plurality of first touch electrode lines TEL1 may be drive touch electrodes, and the plurality of second touch electrodes TE2 constituting each of the plurality of second touch electrode lines TEL2 may be sense touch electrodes. In this case, each of the plurality of first touch electrode lines TEL1 may correspond to a drive touch electrode line, and each of the plurality of second touch electrode lines TEL2 may correspond to a sense touch electrode line.
[0169] Reference Figure 5 In addition to the plurality of first touch electrode lines TEL1 and the plurality of second touch electrode lines TEL2, the touch sensor metal for touch sensing may further include a plurality of touch wirings TL. The plurality of touch wirings TL may include one or more first touch wirings TL1 connected to each of the plurality of first touch electrode lines TEL1, and one or more second touch wirings TL2 connected to each of the plurality of second touch electrode lines TEL2.
[0170] Reference Figure 5 Each of the plurality of first touch electrode lines TEL1 may include a plurality of first touch electrodes TE1 arranged in the same row (or column) and one or more first bridge metals BRG1 electrically connecting the plurality of first touch electrodes TE1. Here, the first bridge metal BRG1 connecting two adjacent first touch electrodes TE1 may be a metal integrated with the two adjacent first touch electrodes TE1, or may be a metal connected to the two adjacent first touch electrodes TE1 through a contact hole.
[0171] Each of the plurality of second touch electrode lines TEL2 may include a plurality of second touch electrodes TE2 arranged in the same column (or row) and one or more second bridge metals BRG2 electrically connecting the plurality of second touch electrodes TE2. Here, the second bridge metal BRG2 connecting two adjacent second touch electrodes TE2 may be a metal integrated with the two adjacent second touch electrodes TE2, or may be a metal connected to the two adjacent second touch electrodes TE2 through a contact hole.
[0172] Here, the first bridge metal BRG1 or the second bridge metal BRG2 connected to the first touch electrode TE1 or the second touch electrode TE2 through the contact hole may be referred to as a 'connection pattern'.
[0173] In a region where the first touch electrode line TEL1 and the second touch electrode line TEL2 intersect (ie, a touch electrode line intersecting region), the first bridge metal BRG1 and the second bridge metal BRG2 may intersect.
[0174] In this manner, in the touch electrode line intersection region, since the first bridge metal BRG1 and the second bridge metal BRG2 intersect, the first bridge metal BRG1 and the second bridge metal BRG2 may be disposed in different layers.
[0175] Therefore, in order to arrange the plurality of first touch electrode lines TEL1 and the plurality of second touch electrode lines TEL2 to intersect, the plurality of first touch electrodes TE1, the plurality of first bridge metals BRG1, the plurality of second touch electrodes TE2, and the plurality of second bridge metals BRG2 may be provided in two or more layers.

That is, the first touch electrode TE1 disposed at the outermost end among the plurality of first touch electrodes TE1 included in one first touch electrode line TEL1 may be electrically connected to the corresponding first touch pad TP1 through the first touch wiring TL1.
[0177] Each of the plurality of second touch electrode lines TEL2 may be electrically connected to a corresponding second touch pad TP2 through one or more second touch wirings TL2. That is, a second touch electrode TE2 disposed at an outermost end among the plurality of second touch electrodes TE2 included in one second touch electrode line TEL2 may be electrically connected to a corresponding second touch pad TP2 through a second touch wiring TL2.
[0178] Already referenced Figure 5The embodiment of the touch configuration is described. Meanwhile, the display device 100 according to the embodiment of the present disclosure may be driven at a wide angle or a narrow angle. Wide-angle driving may mean that light emitted from the display panel 110 is emitted at a relatively wide viewing angle. Narrow-angle driving may mean that light emitted from the display panel 110 is emitted at a relatively narrow viewing angle. Figure 6 、 Figure 7 and Figure 8 Describe wide-angle driving and narrow-angle driving.
[0179] Figure 6 、 Figure 7 and Figure 8 A display panel 110 having a plurality of sub-pixels emitting light at a narrow angle or a wide angle according to an embodiment of the present disclosure is shown.
[0180] exist Figure 6 , a display panel 110 provided with a plurality of sub-pixels is shown.
[0181] The plurality of sub-pixels SP may be arranged in a matrix form.
[0182] The plurality of sub-pixels SP may be grouped in a column direction of the display panel 110. That is, the display panel 110 may include a plurality of sub-pixel groups SPG.
[0183] Reference Figure 6 For ease of description, it is assumed that 20 sub-pixels SP are provided on the display panel 110. Five sub-pixel groups SPG may be provided on the display panel 110. Each sub-pixel group SPG may include four sub-pixels.
[0184] Reference Figure 6 , a first subpixel group SPG1 may be disposed on the leftmost side of the display panel 110, and a fifth subpixel group SPG5 may be disposed on the rightmost side of the display panel 110. A second subpixel group SPG2, a third subpixel group SPG3, and a fourth subpixel group SPG4 may be disposed between the first subpixel group SPG1 and the fifth subpixel group SPG5.
[0185] The first sub-pixel group SPG1 may be electrically connected to the first narrow angle control line P1 and the first wide angle control line S1. The first narrow angle control line P1 and the first wide angle control line S1 may be electrically connected to the sub-pixels included in the first sub-pixel group SPG1.
[0186] The second sub-pixel group SPG2 may be electrically connected to the second narrow-angle control line P2 and the second wide-angle control line S2. The second narrow-angle control line P2 and the second wide-angle control line S2 may be electrically connected to the sub-pixels included in the second sub-pixel group SPG2.

The third narrow angle control line P3 and the third wide angle control line S3 may be electrically connected to the subpixels included in the third subpixel group SPG3.
[0188] The fourth subpixel group SPG4 may be electrically connected to the fourth narrow angle control line P4 and the fourth wide angle control line S4. The fourth narrow angle control line P4 and the fourth wide angle control line S4 may be electrically connected to the subpixels included in the fourth subpixel group SPG4.
[0189] The fifth subpixel group SPG5 may be electrically connected to the fifth narrow angle control line P5 and the fifth wide angle control line S5. The fifth narrow angle control line P5 and the fifth wide angle control line S5 may be electrically connected to the subpixels included in the fifth subpixel group SPG5.
[0190] The plurality of sub-pixel groups SPG may emit light at a wide angle or a narrow angle according to control signals supplied to the narrow-angle control line P and the wide-angle control line S.
[0191] Reference Figure 6 , the sub-pixel groups SPG are grouped in the column direction, but the sub-pixel groups SPG may also be grouped in the row direction according to the arrangement of the narrow-angle control lines P and the wide-angle control lines S.
[0192] Each of the plurality of sub-pixels SP may include a plurality of transistors, capacitors, one or more light emitting devices, and the like.
[0193] The plurality of sub-pixels SP may include a driving transistor DT and one or more light-emitting devices ED, and the plurality of sub-pixels SP may be designed in various ways, such as 2T1C, 3T1C, and 6T1C. The plurality of sub-pixels SP may be any of sub-pixels that do not require characteristic compensation, sub-pixels to which an internal compensation method is applied, and sub-pixels to which an external compensation method is applied. Since the sub-pixels SP may be designed in various ways, the characteristics of the driving transistor DT and the light-emitting device ED included in the sub-pixels SP will be described below, and descriptions of other elements included in the sub-pixels SP may be omitted.
[0194] Reference Figure 6 , shows a portion of an equivalent circuit of one sub-pixel SP_a included in the first sub-pixel group SPG1.
[0195] The sub-pixel SP_a may include a driving transistor DT, a first light emission control transistor Ts, a second light emission control transistor Tp, a first light emitting device ED_S, and a second light emitting device ED_P.
[0196] By supplying a voltage to the gate node of the driving transistor DT, a driving current Id may flow through the driving transistor DT. The driving current Id may be supplied to the first light emitting device ED_S or the second light emitting device ED_P. The first light emitting device ED_S and the second light emitting device ED_P may emit light having a brightness corresponding to the driving current Id.
[0197] The first emission control transistor Ts may be electrically connected between the drive transistor DT and the first light-emitting device ED_S. A wide-angle control signal S_sel may be supplied to a gate node of the first emission control transistor Ts. Based on the wide-angle control signal S_sel, the first emission control transistor Ts may control the electrical connection between the drive transistor DT and the first light-emitting device ED_S. The wide-angle control signal S_sel may be a voltage of a predetermined level and may be expressed as a high-level signal or a low-level signal.
[0198] The second emission control transistor Tp can be electrically connected between the driving transistor DT and the second light-emitting device ED_P. A narrow-angle control signal P_sel can be supplied to the gate node of the second emission control transistor Tp. Based on the narrow-angle control signal P_sel, the second emission control transistor Tp can control the electrical connection between the driving transistor DT and the second light-emitting device ED_P. The narrow-angle control signal P_sel can be a voltage of a predetermined level and can be expressed as a high-level signal or a low-level signal.
[0199] Reference Figure 7 When the first light emission control transistor Ts is turned on and the second light emission control transistor Tp is turned off, the first light emitting device ED_S may be supplied with the driving current Id. When the first light emitting device ED_S emits light, the sub-pixel SP_a may emit light while maintaining the wide angle WA.
[0200] Reference Figure 8 If the second light emission control transistor Tp is turned on and the first light emission control transistor Ts is turned off, the second light emitting device ED_P may receive the driving current Id. When the second light emitting device ED_P emits light, the sub-pixel SP_a may emit light while maintaining the narrow angle NA.
[0201] When the sub-pixel SP_a emits light at a wide angle WA, the viewing angle can be wider than when the sub-pixel SP_a emits light at a narrow angle NA. In this case, not only users in front of the display panel 110 but also users on the side of the display panel 110 can view the image displayed on the display panel 110. When the viewing angle is wide, all users within the wide viewing angle can see the image, so this can be called "sharing mode," "sharing mode," or "sharing drive."
[0202] If the sub-pixel SP_a emits light at a narrow angle NA, the viewing angle can be narrower than when the sub-pixel SP_a emits light at a wide angle WA. In this case, only users in front of or close to the front of the display panel 110 can view the image displayed on the display panel 110. When the viewing angle is narrow, only users within the narrow viewing angle can see the image, so this can be called "privacy mode" or "privacy drive."
[0203] Meanwhile, the viewing angle may be adjusted by a light refraction structure (not shown) such as a lens or a viewing angle adjustment layer. In the following, for ease of explanation, it is assumed that the viewing angle is controlled by a lens.
