The plurality of third voltage supply lines Vssh extend in a direction substantially parallel to the first direction DR1.

[0070] In some embodiments, the plurality of first voltage supply lines are configured to provide a first reference voltage signal (e.g., a high reference voltage signal). The plurality of second voltage supply lines Vssv and the plurality of third voltage supply lines Vssh are configured to provide a second reference voltage signal (e.g., a low reference voltage signal). Optionally, the first reference voltage signal is a constant voltage signal, the second reference voltage signal is a constant voltage signal, and the voltage level of the first reference voltage signal is higher than the voltage level of the second reference voltage signal.

[0071] In some embodiments, a plurality of third voltage supply lines Vssh and a plurality of first fan-out connection lines FIPh are located in the same layer; and a plurality of second voltage supply lines Vssv and a plurality of second fan-out connection lines FIPv are located in the same layer. Optionally, a plurality of third voltage supply lines Vssh and a plurality of first fan-out connection lines FIPh are located in the second signal line layer. Optionally, a plurality of second voltage supply lines Vssv and a plurality of second fan-out connection lines FIPv are located in the third signal line layer.

[0072] In some embodiments, the plurality of second voltage supply lines Vssv and the plurality of third voltage supply lines Vssh form an interconnected voltage supply network. In some embodiments, each of the plurality of second voltage supply lines Vssv is connected to one or more third voltage supply lines Vssh through one or more vias (e.g., one or more vias extending through the second planarization layer PLN2). Figure 4 and Figure 6 The triangle marks in denoted connections between corresponding second voltage supply lines among the plurality of second voltage supply lines Vssv and corresponding third voltage supply lines among the plurality of third voltage supply lines Vssh.

[0073] In some embodiments, the array substrate includes a first partition Z1 and a second partition Z2 outside the first partition Z1. The first partition Z1 includes a plurality of first sub-pixel rows, and the second partition Z2 includes a plurality of second sub-pixel rows. The plurality of first sub-pixel rows are different from the plurality of second sub-pixel rows. In some embodiments, the first partition Z1 and the second partition Z2 are located in the display area of ​​the array substrate.

[0074] In some embodiments, the connections (circle marks) between the plurality of first fan-out connection lines FIPh and the plurality of second data lines DL2 and the connections (square marks) between the plurality of first fan-out connection lines FIPh and the plurality of second fan-out connection lines FIPv are located in the first zone Z1. In some embodiments, the connections (triangle marks) between the plurality of second voltage supply lines Vssv and the plurality of third voltage supply lines Vssh are located in the second zone Z2.

[0075] In some embodiments, the connections (circle marks) between the plurality of first fan-out connection lines FIPh and the plurality of second data lines DL2 located in the first partition Z1 and the connections (square marks) between the plurality of first fan-out connection lines FIPh and the plurality of second fan-out connection lines FIPv constitute a first group of connections. In some embodiments, the connections between the plurality of second voltage supply lines Vssv and the plurality of third voltage supply lines Vssh located in the second partition Z2 include one or more second groups of connections between the plurality of second voltage supply lines Vssv and the plurality of third voltage supply lines Vssh. In some embodiments, each of the one or more second groups of connections located in the second partition Z2 has the same pattern as the first group of connections located in the first partition Z1. In some embodiments, the first group of connections and the one or more second groups of connections are substantially uniformly distributed in the array substrate, for example, along the second direction DR2.

[0076] The inventors of the present disclosure have discovered that enhanced display uniformity can be achieved by having one or more second sets of connections have the same pattern as the first set of connections and by having the first set of connections and the one or more second sets of connections substantially uniformly distributed in the array substrate.

[0077] In some embodiments, an interconnected voltage supply network including a plurality of second voltage supply lines Vssv and a plurality of third voltage supply lines Vssh is electrically connected to the peripheral voltage supply line to receive a second reference voltage signal. Optionally, the interconnected voltage supply network is electrically connected to the cathode of the light emitting element in the array substrate and serves as an auxiliary cathode.

[0078] In the field of AMOLED smartphones, a prominent trend in recent developments is the pursuit of narrow borders, especially achieving border sizes of 1.0 mm or less on the left, right and top edges of the screen. However, it is still relatively difficult to reduce the size of the lower border, thereby limiting the screen-to-body ratio. To solve this problem, a new design method called "fanout connecting lines in display area" has emerged, which significantly reduces the size of the lower border. Figures 3 to 6 The fan-out connection lines depicted in exemplify the fan-out connection line technique in the display area.

[0079] In the related array substrate, the fan-out line is only arranged in the lower frame, and the fan-out line and the touch signal line in the lower frame occupy a large amount of space. The inventor of the present disclosure found that by making the fan-out connection line at least partially located in the display area, the frame size of the array substrate can be significantly reduced.

[0080] Figure 7 is a schematic diagram showing the structure of a portion of an array substrate in some embodiments of the present disclosure. Figure 8 is a plan view of an array substrate in some embodiments of the present disclosure. Figure 7 and Figure 8 In some embodiments, the array substrate has a display area DA and a peripheral area PA. In some embodiments, the array substrate includes: a base substrate BS; a plurality of light emitting elements LE, which are located on the base substrate BS and in the display area DA; an encapsulation layer EN, which is located on a side of the plurality of light emitting elements LE away from the base substrate BS to encapsulate the plurality of light emitting elements LE; an insulating layer IN, which is located on the base substrate BS; a first barrier wall BW1, which is located in the peripheral area PA and on a side of the insulating layer IN away from the base substrate BS, the first barrier wall BW1 forming a first enclosure substantially surrounding the first area EA1; and a second barrier wall BW2, which is located in the peripheral area PA and on a side of the insulating layer IN away from the base substrate BS. The second barrier wall BW2 forms a second enclosure substantially surrounding the second area EA2. Optionally, the second area EA2 surrounds the first area EA1.

[0081] As used herein, the term "peripheral region" refers to a region of an array substrate in a display panel where various circuits and wires are disposed to transmit signals to the display substrate. In order to increase the transparency of the display device, opaque or light-proof components of the display device (e.g., a battery, a printed circuit board, a metal frame) may be arranged in the peripheral region rather than in the display region.

[0082] In some embodiments, the encapsulation layer EN includes a first inorganic encapsulation sublayer SUB1, an organic encapsulation sublayer SUB2, and a second inorganic encapsulation sublayer SUB3. In some embodiments, at least one inorganic sublayer of the encapsulation layer EN extends from the display area DA to the peripheral area PA. In one example, the first inorganic encapsulation sublayer SUB1 and the second inorganic encapsulation sublayer SUB3 extend from the display area DA to the peripheral area PA. Optionally, the first inorganic encapsulation sublayer SUB1, the organic encapsulation sublayer SUB2, and the second inorganic encapsulation sublayer SUB3 all extend from the display area DA to the peripheral area PA. Optionally, at least one inorganic sublayer of the encapsulation layer EN is located on the side of the organic encapsulation sublayer SUB2 away from the base substrate BS. Optionally, at least one inorganic sublayer of the encapsulation layer EN is located on the side of the first barrier wall BW1 away from the base substrate BS.

[0083] Each of the plurality of light emitting elements LE includes an anode AD, a light emitting layer EL on the anode AD, an organic material layer OL on a side of the light emitting layer EL away from the substrate BS, and a cathode layer CD on a side of the organic material layer OL away from the substrate BS. Optionally, the organic material layer OL and the cathode layer CD may be formed in an open mask process.

[0084] In some embodiments, the array substrate further comprises a planarization layer PLN located on a side of the plurality of thin film transistors away from the base substrate BS. The anode AD is electrically connected to the drain D of a corresponding one of the plurality of thin film transistors through a via extending through the planarization layer PLN.

[0085] In some embodiments, the array substrate further includes a pixel defining layer PDL located on a side of the planarization layer PLN away from the base substrate BS. The pixel defining layer PDL defines a plurality of sub-pixel openings for accommodating the light emitting layer EL.

[0086] Various suitable materials can be used to manufacture the first barrier wall BW1 and the second barrier wall BW2. In one example, the first barrier wall BW1 and the second barrier wall BW2 are made of an organic material. In another example, the first barrier wall BW1 and the second barrier wall BW2 are made of the same organic material as the organic encapsulation sublayer SUB2 of the encapsulation layer EN. In another example, the first barrier wall BW1, the second barrier wall BW2, and the organic encapsulation sublayer SUB2 are located in the same layer. As used herein, the term "same layer" refers to the relationship between layers formed simultaneously in the same step. In one example, when the first barrier wall BW1 and the organic encapsulation sublayer SUB2 are formed due to one or more steps of the same patterning process performed in the material deposited in the same deposition process, the first barrier wall BW1 and the organic encapsulation sublayer SUB2 are located in the same layer. In another example, by simultaneously performing the steps of forming the first barrier wall BW1 and the steps of forming the organic encapsulation sublayer SUB2, the first barrier wall BW1 and the organic encapsulation sublayer SUB2 can be formed in the same layer. The term "same layer" does not always mean that the thickness of the layer or the height of the layer in a cross-sectional view is the same.

[0087] Fig. 9 Schematic diagram showing a display area and a peripheral area in an array substrate according to some embodiments of the present disclosure. Fig. 9 In some embodiments, the peripheral area PA includes a first sub-area PA1 located at the first side S1 of the display area DA, a second sub-area PA2 located at the second side S2 of the display area DA, a third sub-area PA3 located at the third side S3 of the display area DA, and a fourth sub-area PA4 located at the fourth side S4 of the display area DA. Optionally, the first side S1 and the fourth side S4 are opposite to each other. Optionally, the second side S2 and the third side S3 are opposite to each other. Optionally, the first sub-area PA1 is a sub-area where a plurality of signal lines are connected to an integrated circuit (e.g., an integrated touch circuit).

[0088] In some embodiments, the first sub-region PA1 includes a side region SR and one or more corner regions (e.g., a first corner region CR1 and a second corner region CR2). The one or more corner regions are respectively located at the corners of the array substrate. The one or more corner regions respectively connect the side region SR to one or more adjacent sub-regions of the peripheral region PA. For example, the first corner region CR1 connects the side region SR to the second sub-region PA2, and the second corner region CR2 connects the side region SR to the third sub-region PA3.

[0089] Fig.10 is a schematic diagram showing the layout of signal lines in the peripheral area of ​​a related array substrate. Fig.10 , the relevant array substrate includes a plurality of signal lines SL (eg, a plurality of touch signal lines) located in a peripheral area PA of the relevant array substrate. Fig.10 Can depict Fig. 9 Layout of multiple signal lines SL in the side region SR (located in the lower frame region) depicted in FIG.

[0090] In the relevant array substrate, the plurality of signal lines SL at least partially cross the barrier walls (including the first barrier wall BW1 and the second barrier wall BW2). In the relevant array substrate, the fan-out lines are usually arranged in the same area. However, in the array substrate having the fan-out connection lines in the display area DA, Fig.10 The signal line layout depicted in FIG. 1 is not suitable because in the array substrate with fan-out connection lines in the display area DA, the lower frame area is significantly reduced, and thus there is not enough space for the plurality of signal lines SL.

[0091] Fig.11 is a schematic diagram showing the layout of signal lines in a peripheral area in a related array substrate. Fig.11 A plurality of signal lines SL may be depicted in Fig. 9 The layout of the corner area (e.g., the first corner area CR1) depicted in FIG. In this area, the layout of the plurality of signal lines SL is used to ensure the integrity of the signal lines. The plurality of signal lines SL are arranged as close as possible to the barrier wall (e.g., the first barrier wall BW1). Fig.11 As shown, in this area, a plurality of signal lines SL are located between the first barrier rib BW1 and the display area DA, wherein the first barrier rib BW1 is the barrier rib closest to the display area DA. For example, the first barrier rib BW1 separates the display area DA from all other barrier ribs (including the second barrier rib BW2).

[0092] In some embodiments, the corner region includes a first sub-region RA, in which a pixel defining layer exists, and the array substrate includes a plurality of openings AP extending through the pixel defining layer in the first sub-region RA. The plurality of openings AP are arranged in a grid pattern. In some embodiments, the corner region also includes a second sub-region RB, in which a layer including an organic material (e.g., a polymer material) is removed. For example, in the second sub-region RB, the planarization layer and the pixel defining layer are completely removed.

[0093] Reference Fig.11 , the first sub-region RA is separated from the barrier wall by the second sub-region RB, so the first sub-region RA is farther from the barrier wall. Although the grid pattern of the pixel defining layer exists in the first sub-region RA, the organic encapsulation sublayer of the encapsulation layer can flatten the first sub-region RA. Therefore, a plurality of signal lines can be disposed in the first sub-region RA.

[0094] The second sub-region RB is closer to the barrier wall. In one example, the second sub-region RB substantially does not have a plurality of signal lines SL. For example, a plurality of signal lines SL other than a ground line are disposed in the first sub-region RA, and the ground line is disposed in the second sub-region RB. In one example, the signal line in the first sub-region RA extends in a direction substantially parallel to a boundary between the first sub-region RA and the second sub-region RB.

[0095] In the related array substrate, one or more inter-barrier regions IBR have substantially no signal lines. Fig.11 In the corner regions depicted in FIG, one or more inter-barrier regions IBR do not have any signal lines at all. Fig.10 In the side regions depicted in FIG. 1 , one or more signal lines partially or completely cross one or more barrier ribs. However, no signal line extends at least partially in the inter-barrier region in a direction substantially parallel to one or more barrier ribs.

[0096] As described above, the fan-out connection line technology in the display area greatly reduces the size of the lower frame (e.g., including the side area and the corner area). The layout of the signal line (e.g., the touch signal line) in the related array substrate is no longer applicable to the array substrate using the fan-out connection line technology in the display area. The inventors of the present disclosure have discovered a novel and unique structure of an array substrate that effectively arranges the signal line in a more limited space with a more sophisticated layout in the narrow frame area.

[0097] Therefore, the present disclosure provides, in particular, an array substrate and a display device, which substantially eliminate one or more problems caused by the limitations and disadvantages of the prior art. On the one hand, the present disclosure provides an array substrate. In some embodiments, the array substrate includes one or more barrier walls and a plurality of signal lines located in a peripheral area. Optionally, the peripheral area includes an inner area, an outer area, and one or more barrier inter-areas. Optionally, the inner area is located between the display area and the barrier wall closest to the display area. Optionally, each barrier inter-area in the one or more barrier inter-areas is located between two adjacent barrier walls. Optionally, the outer area is located on the side of the barrier wall farthest from the display area away from the display area. Optionally, the plurality of signal lines include one or more first signal lines, which extend in a direction substantially parallel to at least one barrier wall in at least one of the one or more barrier inter-areas.

[0098] Fig.12 is a schematic diagram showing the layout of signal lines in a peripheral area of ​​an array substrate according to some embodiments of the present disclosure. Fig.12 A plurality of signal lines SL may be depicted in Fig. 9 The layout of the side region SR (located in the lower frame area) depicted in FIG. Fig.12 In some embodiments, the array substrate includes one or more barrier walls (e.g., a first barrier wall BW1, a second barrier wall BW2, and a third barrier wall BW3). In some embodiments, the peripheral region of the array substrate includes an inner region IR, an outer region OR, and one or more inter-barrier regions IBR. The inner region IR is located between the display area DA and the barrier wall (e.g., the first barrier wall BW1) closest to the display area DA. Each of the one or more inter-barrier regions IBR may be connected to the display area DA. Figure 8 The outer region OR is located on the side of the barrier wall farthest from the display area DA away from the display area DA. In one example, the outer region OR is located between the barrier wall farthest from the display area DA and the integrated circuit connected to the signal line in the peripheral area.

[0099] In some embodiments, the array substrate includes one or more first signal lines SL1, multiple second signal lines SL2, and multiple third signal lines SL3 in the peripheral area. In some embodiments, the one or more first signal lines SL1, multiple second signal lines SL2, and multiple third signal lines SL3 include touch signal lines connected to the touch integrated circuit.

[0100] In some embodiments, one or more first signal lines SL1 extend in a direction substantially parallel to at least one barrier wall in at least one of the one or more inter-barrier regions IBR. In some embodiments, each of the one or more first signal lines SL1 includes a first portion and a second portion connected to each other. The first portion extends in a direction substantially parallel to at least one barrier wall in at least one of the one or more inter-barrier regions IBR. Fig.12 In one example depicted in FIG, the first portion extends within the barrier inter-barrier region between the first barrier rib BW1 and the second barrier rib BW2. The first portion extends in a direction substantially parallel to the first barrier rib BW1, the second barrier rib BW2, and the third barrier rib BW3. The second portion intersects at least one barrier rib. In one example, the second portion intersects the second barrier rib BW2 and the third barrier rib BW3. As used herein, the term "substantially parallel" refers to an angle in the range of 0 degrees to about 45 degrees, such as 0 degrees to about 5 degrees, 0 degrees to about 10 degrees, 0 degrees to about 15 degrees, 0 degrees to about 20 degrees, 0 degrees to about 25 degrees, 0 degrees to about 30 degrees.

[0101] In some embodiments, the length L1 of the first portion extending in at least one of the one or more inter-barrier regions IBR is at least 1.5 times (e.g., at least 2.0 times, at least 2.5 times, at least 3.0 times, at least 3.5 times, at least 4.0 times, at least 4.5 times, at least 5.0 times, at least 5.5 times, at least 6.0 times, at least 6.5 times, at least 7.0 times, at least 7.5 times, at least 8.0 times, at least 8.5 times, at least 9.0 times, at least 9.5 times, at least 10.0 times) of the corresponding inter-barrier distance ibd of the corresponding inter-barrier region in the one or more inter-barrier regions IBR. As used herein, the term "inter-barrier distance" refers to the shortest distance between two adjacent barrier walls. In one example, the inter-barrier distance is the distance along the second direction DR2. In one example, the first direction DR1 and the second direction DR2 intersect each other. In another example, the second direction DR2 is the direction from the display area DA to the peripheral area. In another example, the first direction DR1 is substantially parallel to a boundary between the display area DA and the peripheral area.

[0102] In some embodiments, the orthographic projection of the first portion on the substrate substrate does not substantially overlap with the orthographic projection of any barrier wall on the substrate substrate (e.g., does not overlap with at least 80% of the orthographic projection of any barrier wall on the substrate substrate, does not overlap with at least 85% of the orthographic projection of any barrier wall on the substrate substrate, does not overlap with at least 90% of the orthographic projection of any barrier wall on the substrate substrate, does not overlap with at least 95% of the orthographic projection of any barrier wall on the substrate substrate, does not overlap with at least 98% of the orthographic projection of any barrier wall on the substrate substrate, does not overlap with at least 99% of the orthographic projection of any barrier wall on the substrate substrate, or does not overlap with the orthographic projection of any barrier wall on the substrate substrate at all). In some embodiments, the orthographic projection of the second portion on the substrate substrate at least partially overlaps with the orthographic projection of at least one barrier wall on the substrate substrate.

[0103] In some embodiments, the one or more first signal lines SL1 do not exist in the inner region IR.

[0104] In some embodiments, the plurality of second signal lines SL2 extend at least partially in the inner region IR and at least partially cross the one or more inter-barrier regions IBR. Optionally, the plurality of second signal lines SL2 at least partially cross the outer region OR. In some embodiments, the total length L2 of the portion of each of the plurality of second signal lines SL2 located in the corresponding inter-barrier region of the one or more inter-barrier regions IBR is in the range of 1.0 to 1.5 times (e.g., 1.0 to 1.1 times, 1.1 to 1.2 times, 1.2 to 1.3 times, 1.3 to 1.4 times, or 1.4 to 1.5 times) of the corresponding inter-barrier distance ibd of the corresponding inter-barrier region of the one or more inter-barrier regions IBR.

[0105] In some embodiments, a portion of each of the plurality of second signal lines SL2 located in a corresponding barrier inter-region in one or more barrier inter-regions IBR extends in a direction that is not parallel to the one or more barrier walls. Optionally, a portion of each of the plurality of second signal lines SL2 located in a corresponding barrier inter-region in one or more barrier inter-regions IBR extends in the second direction DR2.

[0106] In some embodiments, each of the plurality of second signal lines SL2 includes a third portion and a fourth portion connected to each other. The third portion extends in a direction substantially parallel to at least one barrier rib in the inner region IR. Fig.12In one example depicted in FIG, the third portion extends in a direction substantially parallel to the first barrier rib BW1, the second barrier rib BW2, and the third barrier rib BW3. The fourth portion intersects at least one barrier rib. In one example, the fourth portion intersects the first barrier rib BW1, the second barrier rib BW2, and the third barrier rib BW3.

[0107] In some embodiments, the orthographic projection of the third portion on the substrate substrate does not substantially overlap with the orthographic projection of any barrier wall on the substrate substrate (e.g., at least 80% does not overlap with the orthographic projection of any barrier wall on the substrate substrate, at least 85% does not overlap with the orthographic projection of any barrier wall on the substrate substrate, at least 95% does not overlap with at least 90% of the orthographic projection of any barrier wall on the substrate substrate, at least 98% does not overlap with the orthographic projection of any barrier wall on the substrate substrate, at least 99% does not overlap with the orthographic projection of any barrier wall on the substrate substrate, or does not overlap at all with the orthographic projection of any barrier wall on the substrate substrate). In some embodiments, the orthographic projection of the fourth portion on the substrate substrate at least partially overlaps with the orthographic projection of at least one barrier wall on the substrate substrate.

[0108] In some embodiments, each of the plurality of third signal lines SL3 includes a fifth portion and a sixth portion connected to each other. The fifth portion and the sixth portion extend in the outer region OR. The fifth portion extends in a direction substantially parallel to at least one barrier rib. Fig.12 In one example depicted in FIG. 5 , the fifth portion extends in a direction substantially parallel to the first barrier rib BW1 , the second barrier rib BW2 , and the third barrier rib BW3 . The sixth portion extends in a direction substantially parallel to the second direction DR2 .

[0109] Fig.13A is a schematic diagram showing the layout of signal lines in a peripheral area of ​​an array substrate according to some embodiments of the present disclosure. Fig.13A Can be depicted from Fig. 9 Layout of multiple signal lines from the side area SR depicted in the figure to the corner area (e.g., the first corner area CR1). In order to be consistent with the shape of the edge of the display area DA in this area, the multiple signal lines SL have a stepped pattern. As used herein, the term "stepped pattern" means that each signal line includes a first line segment FLS1 and a second line segment FLS2 alternately connected together, the first line segment FLS1 and the second line segment FLS2 extend in different directions, and the second line segment FLS2 extends toward the display area DA. Optionally, the first line segment FLS1 extends in a direction substantially parallel to the first direction DR1. The inventors of the present disclosure have found that by having a stepped pattern, an array substrate using a fan-out connection line technology in the display area can fully adapt to the layout of the signal lines in the lower frame.

[0110] In one example, the second line segment FLS2 extends in a consistent direction toward the display area DA.

[0111] In an alternative example, the second line segment FLS2 extends toward the display area DA in at least two different directions, but all extend toward the display area DA. For example, one or more second line segments extend along the second direction DR2, and another one or more second line segments extend in a direction at an angle of 15 degrees relative to the second direction DR2.

[0112] In some embodiments, the stair-shaped pattern includes at least three steps. In one example, each of the plurality of signal lines SL includes at least three second line segments.

[0113] Fig. 13B is a schematic diagram showing the layout of the first line segment and the second line segment according to some embodiments of the present disclosure. Fig. 13B In some embodiments, the first line segment FLS1 has a first average line width alw1, and the second line segment FLS2 has a second average line width alw2. The second average line width alw2 is greater than the first average line width alw1. Optionally, the first average line width alw1 is in a range of 1 μm to 5 μm (e.g., 1 μm to 2 μm, 2 μm to 3 μm, 3 μm to 4 μm, or 4 μm to 5 μm), and the second average line width alw2 is in a range of 5 μm to 25 μm (e.g., 5 μm to 10 μm, 10 μm to 15 μm, 15 μm to 20 μm, or 20 μm to 25 μm). In one example, the first average line width alw1 is about 3.2 μm, and the second average line width alw2 is about 14 μm.

[0114] In some embodiments, the first line segments FLS1 are spaced apart from each other by a first inter-segment distance isd1, and the second line segments FLS2 are spaced apart from each other by a second inter-segment distance isd2. The second inter-segment distance isd2 is greater than the first inter-segment distance isd1. Optionally, the first inter-segment distance isd1 is in a range of 2 μm to 6 μm (e.g., 2 μm to 3 μm, 3 μm to 4 μm, 4 μm to 5 μm, or 5 μm to 6 μm), and the second inter-segment distance isd2 is in a range of 10 μm to 26 μm (e.g., 10 μm to 15 μm, 15 μm to 20 μm, or 20 μm to 26 μm). In one example, the first inter-segment distance isd1 is about 4 μm, and the second inter-segment distance isd2 is about 18 μm.

[0115] In some embodiments, the array substrate includes a pixel defining layer located in the display area DA, and the pixel defining layer is at least partially absent from the peripheral area. In some embodiments, the plurality of signal lines SL are spaced apart from the edge of the pixel defining layer by a distance of no more than 100 μm, for example, no more than 90 μm, no more than 80 μm, no more than 70 μm, no more than 60 μm, no more than 50 μm, no more than 40 μm, no more than 30 μm, or no more than 20 μm. In one example, referring to Fig.13A , the plurality of signal lines SL are spaced apart from the edge EG of the pixel defining layer by a distance of 20 μm.

[0116] Fig. 13C is along Fig.13A A cross-sectional view of the line A-A' in FIG. Fig. 13C In some embodiments, the array substrate includes: a base substrate BS; a first barrier wall BW1, a second barrier wall BW2, and a third barrier wall BW3, which are located on the base substrate BS; at least one sublayer of the encapsulation layer EN, which is located on the side of the first barrier wall BW1, the second barrier wall BW2, and the third barrier wall BW3 away from the base substrate BS; and one or more first signal lines SL1, multiple second signal lines SL2, and multiple third signal lines SL3, which are located on the side of the encapsulation layer EN away from the base substrate BS. Optionally, a first adjacent signal line among the one or more first signal lines includes in the barrier inter-region IBR: a first single segment, which is located in the first conductive layer CL1 but not in the second conductive layer CL2; and a second single segment, which is located in the second conductive layer CL2 but not in the first conductive layer CL1. Optionally, the array substrate includes a first inorganic encapsulation sublayer and a second inorganic encapsulation sublayer (for example, Figure 1 or Figure 2 CVD1 and CVD2 are indicated in the figure, which are located on the side of the first barrier wall BW1, the second barrier wall BW2 and the third barrier wall BW3 away from the substrate BS. Optionally, the first inorganic encapsulation sublayer and the second inorganic encapsulation sublayer are consistent with the shape of each barrier wall. For example, the inclination angle of each barrier wall is substantially the same as or similar to the inclination angle of the first inorganic encapsulation sublayer and the inclination angle of the second inorganic encapsulation sublayer on the corresponding barrier wall.

[0117] In some embodiments, each of the plurality of second signal lines SL2 includes two segments respectively located in the first conductive layer CL1 and the second conductive layer CL2. Optionally, each of the plurality of third signal lines SL3 includes two segments respectively located in the first conductive layer CL1 and the second conductive layer CL2. In one example, the first conductive layer CL1 is Figure 1 or Figure 2 In another example, the second conductive layer CL2 is Figure 1 or Figure 2The second touch metal layer ML2 is depicted in FIG.

[0118] Fig.14 is a schematic diagram showing the layout of signal lines in a peripheral area of ​​an array substrate according to some embodiments of the present disclosure. Fig.14 The layout of the signal lines in the first region R1 and the second region R2 is shown. Fig.12 The area depicted in corresponds to, for example, Fig. 9 The side region SR depicted in FIG. 1 transitions to the corner region (e.g., the first corner region CR1). The second region R2 and Fig. 9 Corresponding to the corner area (e.g., the first corner area CR1) depicted in .

[0119] In some embodiments, the corner region includes a first sub-region RA, in which a pixel defining layer exists, and the array substrate includes a plurality of openings AP extending through the pixel defining layer in the first sub-region RA. The plurality of openings AP are arranged in a grid pattern. In some embodiments, the corner region also includes a second sub-region RB, in which a layer including an organic material (e.g., a polymer material) is removed. For example, in the second sub-region RB, the planarization layer and the pixel defining layer are completely removed.

[0120] Reference Fig.14 , the first sub-region RA is separated from the barrier wall by the second sub-region RB, so the first sub-region RA is farther from the barrier wall. Although the grid pattern of the pixel defining layer exists in the first sub-region RA, the organic encapsulation sublayer of the encapsulation layer can flatten the first sub-region RA. Therefore, a plurality of signal lines can be disposed in the first sub-region RA.

[0121] The second sub-region RB is closer to the barrier wall. In one example, the second sub-region RB substantially does not have a plurality of signal lines SL. For example, a plurality of signal lines SL other than a ground line are disposed in the first sub-region RA, and the ground line is disposed in the second sub-region RB. In one example, the signal line in the first sub-region RA extends in a direction substantially parallel to a boundary between the first sub-region RA and the second sub-region RB.

[0122] Fig.15 is a cross-sectional view of a portion of an array substrate in some embodiments of the present disclosure. Fig.15In some embodiments, the array substrate includes a first barrier wall BW1 and a second barrier wall BW2 spaced apart from each other. The array substrate also includes a first groove GV1, which separates the first barrier wall BW1 from the second barrier wall BW2. Optionally, the array substrate also includes an organic material layer OG and a second groove GV2 that separates the second barrier wall BW2 from the organic material layer OG. The inventors of the present disclosure have found that when the first barrier wall BW1, the second barrier wall BW2, or the organic material layer OG has a relatively large step difference relative to the base substrate BS, the array substrate is prone to depositing residual material at the corner area of ​​the groove (for example, the area indicated by the dotted line), especially when the groove is relatively narrow. When the residual material is a metal or a conductive material, the array substrate is prone to short circuits between adjacent signal lines.

[0123] The inventors of the present disclosure have found that if the width of the groove between two adjacent barrier walls is greater than the sum of the wall widths of the two barrier walls adjacent to the groove, especially when the barrier wall has a relatively large step difference relative to the substrate BS, residual material deposition can be eliminated. For example, the first groove width S1 is greater than the sum of the first wall width W1 of the first barrier wall BW1 and the second wall width W2 of the second barrier wall BW2. As used herein, the term "wall width" refers to the width of the barrier wall along a plane that intersects the barrier wall, the groove, and the organic material layer OG and is perpendicular to the surface of the substrate BS; the term "groove width" refers to the width of the groove along a plane that intersects the barrier wall, the groove, and the organic material layer OG and is perpendicular to the surface of the substrate BS.

[0124] The inventors of the present disclosure have also found that if the width between the barrier wall and the organic material layer is greater than twice the wall width of the barrier wall, residual material deposition can be eliminated, especially when the width of the organic material layer OG is much greater than the wall width of the barrier wall. For example, the second groove width S2 is greater than twice the second wall width W2 of the second barrier wall BW2.

[0125] Fig.16 is a cross-sectional view of a portion of an array substrate in some embodiments of the present disclosure. Fig.16 In some embodiments, the array substrate includes an inner organic material layer IOG, a first groove GV1, a first barrier wall BW1, a second groove GV2, a second barrier wall BW2, a third groove GV3, and an outer organic material layer OOG arranged in sequence in the peripheral area of ​​the array substrate. Optionally, the inner organic material layer IOG includes one or more insulating material layers from the display area DA. In one example, the inner organic material layer IOG includes a first planarization layer PLN1, a second planarization layer PLN2, and a pixel defining layer PDL. Optionally, the groove corresponds to the barrier inter-area as described above.

[0126] In some embodiments, the first groove GV1 has a first groove width S1, the second groove GV2 has a second groove width S2, the third groove GV3 has a third groove width S3, the first barrier wall BW1 has a first wall width W1, and the second barrier wall BW2 has a second wall width W2. The first groove GV1 is located between the inner organic material layer IOG and the first barrier wall BW1, the second groove GV2 is located between the first barrier wall BW1 and the second barrier wall BW2, and the third groove GV3 is located between the second barrier wall BW2 and the outer organic material layer OOG.

[0127] The first groove width S1 is generally relatively small, for example, less than twice the first wall width W1. However, generally, the inclination angle of the internal organic material layer IOG is relatively small, and therefore the step difference of the internal organic material layer IOG relative to the base substrate BS is relatively small. The inventors of the present disclosure have found that when the area corresponding to the first groove GV1 is planarized, the signal line can be arranged in the area. Optionally, the inclination angle of the internal organic material layer IOG is in the range of 5 to 30 degrees, for example, 5 to 10 degrees, 10 to 15 degrees, 15 to 20 degrees, 20 to 25 degrees, or 25 to 30 degrees. Optionally, the step difference of the internal organic material layer IOG relative to the base substrate BS is in the range of 1 μm to 2 μm, for example, 1.0 μm to 1.5 μm, or 1.5 μm to 2.0 μm.

[0128] The second groove width S2 is usually smaller than the sum of the first wall width W1 and the second wall width W2, for example, approximately the same as the first wall width W1 or the second wall width W2. In addition, the second barrier wall BW2 usually has a relatively large step difference relative to the substrate BS. The inventors of the present disclosure have found that it is necessary to avoid setting a signal line in the area corresponding to the second groove GV2.

[0129] The third groove width S3 is generally greater than twice the second wall width W2. Therefore, the inventors of the present disclosure have found that when the region corresponding to the third groove GV3 is planarized, the signal line can be disposed in the region.

[0130] Fig.17 is a cross-sectional view of a portion of an array substrate in some embodiments of the present disclosure. Fig.17In some embodiments, the array substrate includes an inner organic material layer IOG, a first groove GV1, a first barrier wall BW1, a second groove GV2, a second barrier wall BW2, a third groove GV3, a third barrier wall BW3, a fourth groove GV4, and an outer organic material layer OOG arranged in sequence in the peripheral area of ​​the array substrate. Optionally, the inner organic material layer IOG includes one or more insulating material layers from the display area DA. In one example, the inner organic material layer IOG includes a first planarization layer PLN1, a second planarization layer PLN2, a third planarization layer PLN3, and a pixel defining layer PDL. Optionally, the groove corresponds to the barrier inter-area as described above.

[0131] In some embodiments, the first groove GV1 has a first groove width S1, the second groove GV2 has a second groove width S2, the third groove GV3 has a third groove width S3, the fourth groove GV4 has a fourth groove width S4, the first barrier wall BW1 has a first wall width W1, the second barrier wall BW2 has a second wall width W2, and the third barrier wall BW3 has a third wall width W3. The first groove GV1 is located between the inner organic material layer IOG and the first barrier wall BW1, the second groove GV2 is located between the first barrier wall BW1 and the second barrier wall BW2, the third groove GV3 is located between the second barrier wall BW2 and the third barrier wall BW3, and the fourth groove GV4 is located between the third barrier wall BW3 and the outer organic material layer OOG.

[0132] The first groove width S1 is generally relatively small, for example, less than twice the first wall width W1. However, generally, the inclination angle of the internal organic material layer IOG is relatively small, and therefore the step difference of the internal organic material layer IOG relative to the base substrate BS is relatively small. The inventors of the present disclosure have found that when the area corresponding to the first groove GV1 is planarized, the signal line can be arranged in the area. Optionally, the inclination angle of the internal organic material layer IOG is in the range of 5 to 30 degrees, for example, 5 to 10 degrees, 10 to 15 degrees, 15 to 20 degrees, 20 to 25 degrees, or 25 to 30 degrees. Optionally, the step difference of the internal organic material layer IOG relative to the base substrate BS is in the range of 1 μm to 2 μm, for example, 1.0 μm to 1.5 μm, or 1.5 μm to 2.0 μm.

[0133] The second groove width S2 is typically smaller than the sum of the first wall width W1 and the second wall width W2, for example, approximately the same as the first wall width W1 or the second wall width W2. In one example, the second groove width S2 is in the range of 35 μm to 40 μm; the first wall width W1 or the second wall width W2 is in the range of 30 μm to 40 μm. However, the first barrier rib BW1 and the second barrier rib BW2 typically have a relatively small step difference relative to the substrate BS. In one example, the step difference of the first barrier rib BW1 or the second barrier rib BW2 relative to the substrate BS is in the range of 1 μm to 2 μm, for example, 1.0 μm to 1.5 μm, or 1.5 μm to 2.0 μm. The inventors of the present disclosure have found that when the area corresponding to the second groove GV2 is planarized, a signal line can be set in this area.

[0134] The third groove width S3 is generally smaller than the sum of the second wall width W2 and the third wall width W3, for example, approximately the same as the second wall width W2 or the third wall width W3. In addition, the third barrier wall BW3 generally has a relatively large step difference relative to the substrate BS. The inventors of the present disclosure have found that it is necessary to avoid setting a signal line in the area corresponding to the third groove GV3.

[0135] The fourth groove width S4 is generally greater than twice the third wall width W3. Therefore, the inventors of the present disclosure have found that when the region corresponding to the fourth groove GV4 is planarized, the signal line can be disposed in the region.

[0136] The inventors of the present disclosure also discovered that in order to arrange signal lines in the area corresponding to the following grooves, a unique signal line layout can be used to achieve the arrangement of signal lines in the area between the barriers: the grooves do not have sufficient groove width or are adjacent to barrier walls that have a large step difference relative to the substrate.
