[0032] The advantages and features of the present invention and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below but can be implemented in various different forms, and when a part is described as being connected to another part in the following description, this includes not only cases where they are directly connected but also cases where they are electrically connected with other elements in between. In one embodiment of the present invention, the term “connection” between two components may mean that it encompasses both electrical and physical connections.

[0033] Hereinafter, a display device according to an embodiment of the present invention will be described with reference to the drawings related to the embodiments of the present invention.

[0034] FIG. 1 is a drawing showing a display device according to embodiments.

[0035] Referring to FIG. 1, the display device (100) includes a touch panel (110) (or, sensing panel, sensor), a display panel (120), a touch panel driver (130) (or a first driver), and a display panel driver (140) (or a second driver). The touch panel (110) and the touch panel driver (130) constitute a sensing device.

[0036] The touch panel (110) can detect external inputs such as touch, pressure, fingerprint, hovering, proximity, and motion. For example, the touch panel (110) may include sensor electrodes. In one embodiment (e.g., in a mutual capacitance method), the sensor electrodes may include driving electrodes and sensing electrodes. In another embodiment (e.g., in a magnetic capacitance method), the sensor electrodes may be composed of one type of sensor.

[0037] The display panel (120) displays an image. For example, the display panel (120) may be implemented as a self-emissive type display panel, such as an organic light-emitting display panel. In this case, the display panel (120) may include an organic light-emitting diode, an inorganic light-emitting diode, a quantum dot / well light-emitting diode, etc. As another example, the display panel (120) may be implemented as a non-emissive type display panel, such as a liquid crystal display panel. When the display panel (120) is implemented as a non-emissive type, the display device (100) may additionally be provided with a light source, such as a backlight unit.

[0038] In FIG. 1, the touch panel (110) and the display panel (120) are shown separately from each other. However, this is merely to functionally distinguish the touch panel (110) and the display panel (120) within the display device (100). For example, the touch panel (110) may be formed in a separate process from the display panel (120) so that the touch panel (110) and the display panel (120) can be combined (for example, the touch panel (110) is attached to one side of the display panel (120) and combined). That is, the touch panel (110) may be formed as an add-on type. Alternatively, the touch panel (110) may be formed in a single process with the display panel (120) (for example, the process of manufacturing the display panel (120)). That is, the touch panel (110) may be formed as an in-cell type.

[0039] A touch panel (110) may be provided on one side of a display panel (120). For example, the touch panel (110) may be provided on one side (e.g., the top side) of the display panel (120) in the direction in which the image is displayed. In another embodiment, the touch panel (110) may be formed directly on at least one side of the display panel (120) or formed inside the display panel (120). For example, the touch panel (110) may be formed directly on the outer surface of the upper substrate or lower substrate of the display panel (120) (i.e., the upper surface of the upper substrate or the lower surface of the lower substrate), or may be formed directly on the inner surface of the upper substrate (i.e., the lower surface of the upper substrate) or the inner surface of the lower substrate (i.e., the upper surface of the lower substrate).

[0040] The touch panel driving unit (130) is electrically connected to the touch panel (110) to drive the touch panel (110). For example, the touch panel driving unit (130) can provide a driving signal to sensor electrodes and receive a sensing signal from the sensor electrodes.

[0042] In one embodiment, the touch panel driver (130) and the display panel driver (140) may each be implemented as an integrated circuit (IC). In another embodiment, at least a portion of the touch panel driver (130) and the display panel driver (140) may be integrated together within a single IC (or processor).

[0089] In FIG. 5, the display element layer (DPL) is shown to include a light-emitting element (LD) composed of an organic light-emitting diode having a first electrode (AE), a light-emitting layer (EML), and a second electrode (CE), but is not limited thereto. According to an embodiment, the display element layer (DPL) may include an inorganic light-emitting element grown on a nitride-based semiconductor.

[0090] A touch panel (110) may be provided on the encapsulation layer (TFE). The touch panel (110) may be provided directly on the encapsulation layer (TFE) using the encapsulation layer (TFE) as a base layer. In other words, the touch panel (110) may be formed directly on the encapsulation layer (TFE) through a process continuous with the process of forming the encapsulation layer (TFE).

[0091] The touch panel (110) may include insulating layers sequentially stacked on an encapsulation layer (TFE), namely a first insulating layer (YILD), a second insulating layer (YCNT), and a third insulating layer (YPVX). Additionally, the touch panel (110) may include a sensor electrode (SP) disposed between the insulating layers.

[0092] The first insulating layer (YILD) is a buffer layer and may include an inorganic material, but is not limited thereto. Depending on the embodiment, the first insulating layer (YILD) may be omitted.

[0093] A second insulating layer (YCNT) may be provided on the first insulating layer (YILD). The first insulating layer (YILD) is an insulating layer and may include an inorganic material, but is not limited thereto.

[0094] A sensor electrode (SP) may be provided on the second insulating layer (YCNT).

For example, the sensor electrode (SP) may have a mesh structure including a plurality of conductive fine lines (or mesh lines) and may include an opening (or mesh hole) corresponding to the light-emitting element (LD).

[0095] The sensor electrode (SP) can overlap with the second electrode (CE). Interference between the lower configuration of the second electrode (CE) (and the signal applied thereto) and the sensor electrode (SP), that is, noise caused by the lower configuration, can be prevented.

According to an embodiment, dams (DAM1, DAM2) may be formed simultaneously with at least one insulating layer among the insulating layers included in the pixel circuit layer (PCL). The dams (DAM1, DAM2) can prevent liquid organic material from overflowing into the outer region of the substrate (BSL) during the process of forming an organic film contained in the encapsulation layer (TFE), for example, a second encapsulation layer (ENC2).

[0098] FIGS. 6 and 7 are enlarged plan views of the AA region of FIGS. 4. FIGS. 6 and 7 show one intersection region where the first sensor electrode (SP1) and the second sensor electrode (SP2) intersect. The embodiment of FIGS. 6 and 7 can be applied to other intersection regions as well.

[0099] Referring to FIGS. 6 and 7, the first sensor electrode (SP1) may extend in a first direction (DR1). The first sensor electrode (SP1) may include a first sensor electrode (SP11), a second sensor electrode (SP12), and a first bridge pattern (BRP1). The first bridge pattern (BRP1) may connect the first sensor electrode (SP11) and the second sensor electrode (SP12).

[0100] The second sensor electrode (SP2) extends in a second direction (DR2) and may intersect with the first sensor electrode (SP1). The second sensor electrode (SP2) may include a 21st sensor electrode (SP21) (or a first sensor pattern (CP1), a first segment, a first cell, a first region), a 22nd sensor electrode (SP22) (or a second sensor pattern (CP2), a second segment, a second cell, a second region), and a second bridge pattern (BRP2). The 21st sensor electrode (SP21) and the 22nd sensor electrode (SP22) do not overlap with the first sensor electrode (SP1) and may be mutually distinguishable with respect to the first sensor electrode (SP1). The second bridge pattern (BRP2) may connect the 21st sensor electrode (SP21) and the 22nd sensor electrode (SP22) while partially overlapping with the first sensor electrode (SP1). For example, the second bridge pattern (BRP2) can be connected to the 21st sensor electrode (SP21) through the first contact hole (CNT1) and to the 22nd sensor electrode (SP22) through the second contact hole (CNT2).

[0101] In the embodiments, the second bridge pattern (BRP2) (or bridge pattern) may extend in the form of a spiral wound at least once from a first end connected to (or connected to) the 21st sensor electrode (SP21) to a second end connected to the 22nd sensor electrode (SP22). The first end may correspond to the first contact hole (CNT1), and the second end may correspond to the second contact hole (CNT2).

[0102] For example, the second bridge pattern (BPR2) may include a first part (P1) and a second part (P2) separated based on the third node (N3). As illustrated in FIG. 7, the third node (N3) may be connected to the third sensing line (SL3), but is not limited thereto. Any point of the second bridge pattern (BPR2) may become the third node (N3), and the position of the third node (N3) may vary depending on the design requirements of the first resistor (R1) and the second resistor (R2).

[0103] The first part (P1) of the second bridge pattern (BRP2) can be extended spirally by sequentially changing direction from the first contact hole (CNT1) to the first diagonal direction (CDR1), the opposite direction of the second diagonal direction (CDR2), and the opposite direction of the first diagonal direction (CDR1). Each of the first diagonal direction (CDR1) and the second diagonal direction (CDR2) intersects the first direction (DR1) and the second direction (DR2), and the second diagonal direction (CDR2) may intersect the first diagonal direction (CDR1). The second part (P2) of the second bridge pattern (BRP2) can be extended spirally from the third node (N3) in a first diagonal direction (CDR1), a second diagonal direction (CDR2), a direction opposite to the first diagonal direction (CDR1), a direction opposite to the second diagonal direction (CDR2), and a direction opposite to the first diagonal direction (CDR1). At least a portion of each of the first part (P1) and the second part (P2) may have a U-shape, but is not limited thereto.

[0104] In one embodiment, the second bridge pattern (BRP2) may have a double helix structure. For example, as shown in FIG. 6, the first part (P1) may extend clockwise from the first contact hole (CNT1), and the second part (P2) may extend clockwise from the second contact hole (CNT2). However, the second bridge pattern (BRP2) is not limited thereto, and for example, the second bridge pattern (BRP2) may have a single helix structure (see FIG. 14).

[0105] As will be described later with reference to FIG. 11, the second bridge pattern (BRP2) may be included in a Wheatstone bridge circuit. For example, the first resistor (R1) of the first part (P1) and the second resistor (R2) of the second part (P2) may be included in a Wheatstone bridge circuit. Depending on the intensity of the touch, the resistance value of the second bridge pattern (BRP2) (or the resistance value of the first resistor (R1) or the resistance value of the second resistor (R1)) may change, and the voltage of the third node (N3) may change. The touch panel driver (130, see FIG. 1) may detect the intensity of the touch or the pressure of the touch based on the change in the voltage of the third node (N3).

[0106] That is, the first sensor electrode (SP1) and the second sensor electrode (SP2) are configured to detect touch input using capacitance technology, and the second bridge pattern (BPR2) of the second sensor electrode (SP2) can be configured to detect pressure by being arranged in a spiral shape.

[0107] In a case where the second bridge pattern (BRP2) is arranged in a spiral shape, the second bridge pattern (BRP2) (i.e., electrodes for pressure sensing) can be uniformly distributed over the entire surface of the touch panel (110), and accordingly, stable and consistent sensing performance can be provided regardless of the location where pressure is applied. In addition, the second bridge pattern (BRP2) arranged in a spiral shape can reduce the difference in sensitivity that may occur between the central and outer parts of the AA area.

[0108] As described above, the second bridge pattern (BPR2) of the second sensor electrode (SP2) included in the touch sensor can function as a pressure sensor. Compared to a case where the pressure sensor is provided separately from the touch sensor, the manufacturing process of the touch panel (110) and the display device (100, see FIG. 1) including it is simplified and the manufacturing cost is reduced, and the display device can be implemented in a thin form.

[0109] In FIGS. 6 and 7, the second bridge pattern (BRP2) of the second sensor electrode (SP2) is described as extending in a spiral shape, but the embodiment of FIGS. 6 and 7 is not limited thereto. For example, instead of the second bridge pattern (BRP2), the first bridge pattern (BRP1) of the first sensor electrode (SP1) may be extended in a spiral shape.

[0110] FIGS. 8 and FIGS. 9 are enlarged plan views of the AA region of FIG. 4. In FIG. 8, the conductivity patterns of the first conductive layer (CPL1) (hereinafter referred to as the first conductivity patterns) are illustrated, and in FIG. 9, the conductivity patterns of the second conductive layer (CPL2) (hereinafter referred to as the second conductivity patterns) are illustrated. FIG. 10 is a cross-sectional view taken along the second bridge pattern of FIG. 8.

[0111] Referring to FIGS. 8 to 10, the first conductive layer (CPL1) may include a second bridge pattern (BRP2), and the second conductive layer (CPL2) may include a first sensor electrode (SP1), a 21st sensor electrode (SP21) (or a first sensor pattern (CP1)), and a 22nd sensor electrode (SP22) (or a second sensor pattern (CP2)). However, the first and second conductive layers (CPL1, CPL2) are not limited thereto. For example, the second conductive layer (CPL2) may include a second bridge pattern (BRP2), and the first conductive layer (CPL1) may include a first sensor electrode (SP1), a 21st sensor electrode (SP21), and a 22nd sensor electrode (SP22). The third sensing line (SL3) shown in FIG. 7 may be included in the first conductive layer (CPL1) or the second conductive layer (CPL2). For example, the third sensing line (SL3) may be included in the first conductive layer (CPL1) together with the second bridge pattern (BRP2).

[0112] The first and second sensor electrodes (SP1, SP2) may include mesh lines (MSL). Some of the mesh lines (MSL) may extend in a first diagonal direction (CDR1), and other parts of the mesh lines (MSL) may extend in a second diagonal direction (CDR2). The mesh lines (MSL) may intersect each other to define mesh holes (MH). A light-emitting element (LD, see FIG. 5) of the display panel (120) may be exposed through the mesh holes (MH), or light emitted from the light-emitting element (LD) may pass through the mesh holes (MH).

[0113] In one embodiment, the second bridge pattern (BRP2) of the second sensor electrode (SP2) includes mesh lines (MSL), but mesh holes (MH) may not be formed in the second bridge pattern (BRP2). In this case, the resistance value of the second bridge pattern (BRP2) (or the resistance value of the first and second resistors (R1, R2) in FIG. 7) increases, the rate of change of resistance for the same pressure appears larger, and the sensing sensitivity may be improved. However, the second bridge pattern (BRP2) is not limited thereto, and the second bridge pattern (BRP2) may include mesh holes (MH). For example, the second bridge pattern (BRP2) may have a line width corresponding to at least one mesh hole (MH) (or include at least one pair of mesh lines (MSL)) and may be arranged in a spiral shape. The smaller the resistance value of the second bridge pattern (BRP2), the less sensitive the pressure sensing may be to external noise.

[0114] As illustrated in FIG. 9, the first sensor electrode (SP1), the 21st sensor electrode (SP21), and the 22nd sensor electrode (SP22) are provided within the same layer, and are distinguished into different patterns by a boundary line (BDL). In other words, the first sensor electrode (SP1), the 21st sensor electrode (SP21), and the 22nd sensor electrode (SP22) may be distinguished into different electrodes by the mesh pattern being patterned along the boundary line (BDL).

[0115] Referring to FIG. 10, a first conductive layer (CPL1) is provided between a first insulating layer (YILD) and a second insulating layer (YCNT), and a second conductive layer (CPL2) may be provided between a second insulating layer (YCNT) and a third insulating layer (YPVX). A second insulating layer (YCNT) may be provided between the first conductive layer (CPL1) and the second conductive layer (CPL2).

[0116] The 21st sensor electrode (SP21) is connected to the first end or first part (P1) of the 2nd bridge pattern (BRP2) through the first contact hole (CNT1), and the 22nd sensor electrode (SP22) can be connected to the second end or second part (P2) of the 2nd bridge pattern (BRP2) through the second contact hole (CNT2).

[0117] The first and second conductive layers (CPL1, CPL2) may include a conductive material. The conductive material may include metals or alloys thereof, and may include gold (Au), silver (Ag), aluminum (Al), molybdenum (Mo), chromium (Cr), titanium (Ti), nickel (Ni), neodymium (Nd), copper (Cu), platinum (Pt), etc. Additionally, the first and second conductive layers (CPL1, CPL2) may include a transparent conductive material. The transparent conductive material may include silver nanowires (AgNW), ITO (Indium Tin Oxide), IZO (Indium Zinc Oxide), IGZO (Indium Gallium Zinc Oxide), ITZO (Indium Tin Zinc Oxide), carbon nanotubes, graphene, etc.

[0118] The first and second conductive layers (CPL1, CPL2) may be composed of a single layer structure or a multilayer structure. For example, the first and second conductive layers (CPL1, CPL2) may have a three-layer structure of titanium / aluminum / titanium.

[0119] In one embodiment, the first conductive layer (CPL1) and the second conductive layer (CPL2) may include the same material. For example, the second bridge pattern (BRP2) may include the same material as the second sensor electrode (SP21).

[0120] In another embodiment, the first conductive layer (CPL1) and the second conductive layer (CPL2) may comprise mutually different materials. For example, the second bridge pattern (BRP2) and the second sensor electrode (SP21) may comprise mutually different materials. For example, the first conductive layer (CPL1) may comprise a material in which the change in resistance due to pressure is relatively large, and the second conductive layer (CPL2) may comprise a material in which the change in resistance due to pressure is relatively small.

[0121] FIG. 11 is a drawing showing an embodiment of a touch panel driver included in the display device of FIG. 1. FIG. 11 schematically illustrates a touch panel driver (130) connected to the second bridge pattern (BRP2) of FIG. 6 and FIG. 7.

[0122] Referring to FIGS. 6, 7, and 11, the first part (P1) (or first resistor (R1)) of the second bridge pattern (BRP2) is electrically connected between the first node (N1) and the third node (N3), and the second part (P2) (or second resistor (R2)) of the second bridge pattern (BRP2) can be electrically connected between the second node (N2) and the third node (N3).

[0123] Each of the first node (N1) and the second node (N2) can be electrically connected to the touch panel driver (130). For example, with reference to FIGS. 4 and 7, the first node (N1) can be electrically connected to the touch panel driver (130) through the 21st sensor electrode (SP21) and the 2nd sensing line (SL2), and the second node (N2) can be electrically connected to the touch panel driver (130) through the 22nd sensor electrode (SP22) and the 2nd sensing line (SL2). A driving voltage (Vs) can be provided between the first node (N1) and the second node (N2). The third node (N3) can be electrically connected to the touch panel driver (130) through the 3rd sensing line (SL3) of FIG. 7.

[0124] The touch panel driver (130) may include a third resistor (R3), a fourth resistor (R4), and an amplifier circuit (AMP). According to an embodiment, the touch panel driver (130) may further include an analog-to-digital converter and a processor for detecting the output of the amplifier circuit.

[0125] The third resistor (R3) is electrically connected between the first node (N1) and the fourth node (N4), and the fourth resistor (R4) may be electrically connected between the second node (N2) and the fourth node (N4). The third resistor (R3) and the fourth resistor (R4) may be fixed resistors. The first resistor (R1) and the second resistor (R2) may be variable resistors. The first resistor (R1), the second resistor (R2), the third resistor (R3), and the fourth resistor (R4) may be included in a Wheatstone bridge circuit.

[0126] The first input terminal of the amplifier circuit (AMP) is electrically connected to the third node (N3), and the second input terminal of the amplifier circuit (AMP) can be electrically connected to the fourth node (N4).

[0127] The amplifier circuit (AMP) is implemented as an amplifier and can detect electrical flow between the third node (N3) and the fourth node (N4). The amplifier circuit (AMP) can operate as a galvanometer or a voltage measuring device.

[0128] The amplifier circuit (AMP) can output a voltage proportional to the difference between the voltage values ​​provided to the first and second input terminals.

[0129] When no touch input is applied, the product of the resistance value of the first resistor (R1) and the resistance value of the fourth resistor (R4) may be substantially the same as the product of the resistance value of the second resistor (R2) and the resistance value of the third resistor (R3). In this case, the voltage difference between the voltage of the third node (N3) and the voltage of the fourth node (N4) may be 0V.

[0130] When a touch input is applied to the touch panel (110), the shape of the first resistor (R1) or the second resistor (R2) is deformed according to the intensity of the touch, and the resistance value of the first resistor (R1) or the second resistor (R2) may change due to the shape deformation, and accordingly, a voltage difference may occur between the third node (N3) and the fourth node (N4). When a voltage difference occurs between the third node (N3) and the fourth node (N4), the amplifier circuit (AMP) outputs a value other than 0V, and the touch panel driving unit (130) can detect the intensity of the touch or the pressure of the touch by measuring the value output from the amplifier circuit (AMP).

[0131] FIGS. 12, FIGS. 13, and FIGS. 14 are enlarged plan views of the AA region of FIG. 4. FIGS. 12, FIGS. 13, and FIGS. 14 illustrate various embodiments of the second bridge pattern (BRP2) of the first conductive layer (CPL1).

[0132] Referring to FIGS. 6 to 8, FIGS. 12, FIGS. 13, and FIGS. 14, except for the shape of the second bridge pattern (BRP2), the second bridge pattern (BRP2) of FIGS. 12, FIGS. 13, and FIGS. 14 is substantially identical or similar to the second bridge pattern (BRP2) of FIGS. 6 to 8, so redundant description is omitted.

[0133] In one embodiment, as shown in FIG. 12, the second bridge pattern (BRP2) may extend in a spiral shape wound about three times from the first contact hole (CNT1) (or the first node (N1)) to the second contact hole (CNT2) (or the second node (N2)). The second bridge pattern (BRP2) may have a double helix structure, but is not limited thereto. According to an embodiment, the second bridge pattern (BRP2) may extend in a spiral shape wound four or more times.

[0134] In one embodiment, as shown in FIG. 13, the second bridge pattern (BRP2) may extend in the form of a spiral wound about once from the first contact hole (CNT1) (or the first node (N1)) to the second contact hole (CNT2) (or the second node (N2)). The second bridge pattern (BRP2) may have a single spiral structure, but is not limited thereto.

[0135] In one embodiment, as shown in FIG. 14, the second bridge pattern (BRP2) has a single helical structure and can extend in a helical form wound about three times from the first contact hole (CNT1) (or the first node (N1)) to the second contact hole (CNT2) (or the second node (N2)). Even in the case where the second bridge pattern (BRP2) has a single helical structure, the number of wounds of the second bridge pattern (BRP2) may be two or four or more.

[0136] Depending on design conditions such as pressure sensing sensitivity, sensitivity to external noise, the size of the pressure sensing area, and touch sensing sensitivity, the shape (and size) of the second bridge pattern (BRP2) can be varied. For reference, as the resistance value of the second bridge pattern (BRP2) increases, the pressure sensing sensitivity improves, sensitivity to external noise increases, and the touch sensing sensitivity may decrease. The pressure sensing area is a unit sensing area covered by a single second bridge pattern (BRP2).

[0137] FIG. 15 is a block diagram of an electronic device according to one embodiment.

[0138] Referring to FIG. 15, an electronic device (10) according to one embodiment may include a display module (11) (or display device), a processor (12), a memory (13), and a power module (14).

According to an embodiment, the processor (12) may include the touch panel driver (130) of FIG. 1, or detect a touch input and the intensity (or pressure) of the touch input based on a signal provided from the touch panel driver (130).

[0140] The memory (13) may store data information necessary for the operation of the processor (12) or the display module (11).
