[0032] In order to more clearly describe the objectives, technical solutions and advantages of the present disclosure, the following examples of the present disclosure are given. The technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings. As such, the described embodiments are only a portion of the present disclosure and are not all of the embodiments.

"Connected" and similar terms such as "connected to each other" refer to physical or mechanical The term "connection" is not limited to a physical connection, but may include electrical connections, whether direct or indirect.

[0034] Currently, in order to realize a thinner design for display devices (e.g., organic light-emitting diode display devices), In addition, the display panel and the touch structure can be integrated into one. (Flexible Multiple Layer On Cell) touch technology is FMLOC touch technology is born according to the need to combine various electrode layers and various touch structures in the sealing layer. The touch structure can be integrated into the display panel by directly fabricating the appropriate wiring. Display devices that use FMLOC touch technology can not only achieve slimmer displays, , flexible display and flexible touch can further be realized.

[0035] In a display device adopting FMLOC touch technology, a touch drive is provided in the peripheral area of ​​the display device. Signal channel lines are installed to connect the moving electrodes (Tx) and the touch sensing electrodes (Rx). FIG. 1 is a schematic cross-sectional view of the peripheral region of the array substrate. As shown in FIG. The sealing layer 20 is provided on the plate 10. The sealing layer 20 is made up of two inorganic sealing layers 21 and two inorganic sealing layers. and an organic encapsulation layer 22 interposed between the layers 21 and 22, the encapsulation layer 20 being spaced apart from the base substrate 10. Signal wiring connected to the touch driving electrode (Tx) or touch sensing electrode (Rx) on the surface The organic sealing layer 22 is subjected to a leveling process, so that the periphery of the array substrate is A sloped portion in which the thickness gradually decreases is formed in the region. In order to avoid this, the signal wiring 30 is generally formed at a position corresponding to the flat portion of the organic sealing layer 22. This results in a large width in the peripheral area, which is disadvantageous in realizing a narrow frame design for the display device. be.

[0036] FIG. 2 is a schematic cross-sectional view of another array substrate. As shown in FIG. 2, the array substrate , a base substrate 10, a sealing layer 20, a signal wiring 30, a pixel driving layer 40, and a flat layer 50.

The planar layer 50 is located in the display area 11 of the pixel driving layer 40. The organic light emitting element 60 is located on the side of the planar layer 50 away from the pixel driving layer 40. The sealing layer 20 is located on the side of the organic light-emitting element 60 that is farther away from the base substrate 10. The layer 20 includes two inorganic sealing layers 21 and an organic sealing layer 22 interposed between the two inorganic sealing layers 21. The surface of the sealing layer 20 away from the base substrate 10 is provided with a touch drive electrode (Tx) or a touch electrode (Tx). A signal wiring 30 connected to the switch sensing electrode (Rx) is formed. Since the sealing layer 20 on the flat layer 50 is not fixed to the base substrate 10, the distance between the sealing layer 20 on the flat layer 50 and the base substrate 10 is The thickness of the flat layer 50 decreases sharply at the edge thereof, and the organic encapsulation layer 22 undergoes a leveling process. A slope portion is formed in the peripheral region of the array substrate, the thickness of which is gradually decreased. In order to avoid any influence on the wiring 30, the signal wiring 30 is generally placed under the organic sealing layer 22. The flat portion is formed at a position corresponding to the flat portion, i.e., at a position on the flat layer. The width of the frame of the display device using the above method includes the width of the inclined portion and the width of the flat portion, and the width of the flat portion is Because it is large, it is disadvantageous in realizing a narrow frame design.

[0037] On the other hand, with the development of narrow frame designs, the frame of the display device is becoming narrower and narrower. At that time, the only way to reduce the wiring width and wiring spacing is to create a narrow frame design. Therefore, the wiring needs of the display device using the above method are not fully solved.

The orthogonal projection of the first channel line on the base substrate is away from the display area at the first edge. In this way, the array substrate is provided with at least one of the first channel lines. The first channel line is disposed on the side of the first edge away from the display area (i.e., the inclined portion of the sealing layer). ) to reduce the width of the peripheral area, so that the array substrate It is possible to realize a narrow frame or frameless design for the display device to be adopted.

[0039] Hereinafter, an array substrate and a display device according to an embodiment of the present disclosure will be described in detail with reference to the drawings. do.

As shown, the array substrate 100 includes a base substrate 110, a pixel driving layer 150, and a planar layer 160. an organic light-emitting element 170; a sealing layer 120; a first stop wall 130; and a plurality of first channels. The base substrate 110 includes a display area 112 and a periphery of the display area 112. The pixel driving layer 150 is disposed on the base substrate 110. The planarization layer 160 is located on the side of the pixel driving layer 150 away from the base substrate 110. The light emitting element 170 is located on the side of the planar layer 160 away from the pixel driving layer 150. The first stop 20 is located on the side of the organic light emitting element 170 that is away from the base substrate 110. The wall 130 is a first stop wall portion located in the peripheral region 114 and extending along a first direction. A plurality of first channel lines 140 are located in the peripheral region 114 and are formed on the encapsulation layer 132. 120 on the side away from the base substrate 110, and each first channel line 140 is The first channel lines 140 extend along a direction X, and the first channel lines 140 are arranged along a second direction Y. The second direction is substantially perpendicular to the first direction. A pixel for driving a corresponding organic light emitting element so that the corresponding organic light emitting element performs light emission display. In addition, the second direction being perpendicular to the first direction may include a circuit. When the included angle between the first direction and the second direction is equal to 90 degrees, and when the included angle between the first direction and the second direction is equal to 8 This includes the cases where the temperature is greater than 0 degrees and less than 100 degrees.

[0041] As shown in FIGS. 3 and 4, the sealing layer 120 is directly disposed on the base substrate 110 in some areas. Another film layer structure, such as the above-mentioned film, may be placed between the sealing layer 120 and the base substrate 110. A pixel driving layer 150, a flat layer 160, an organic light emitting element 170, etc. may be provided. encapsulates the pixel driving layer 150 and the organic light emitting element 170 formed on the base substrate 110; Water and oxygen in the external environment corrode the pixel driving layer 150 and the organic light emitting device 170. The first stop wall 130 is disposed on the base substrate 110 and is arranged around the The first stop wall 130 is located in the side region 114. The fluid material in the stop layer 120 can be prevented from flowing out of the first stop wall 130. Cut.

[0042] As shown in FIGS. 3 and 4, the encapsulation layer 120 includes an organic encapsulation layer 124 and a planarization layer 160. The first stop 162 includes a first edge 162 extending along a first direction X. The first edge 162 of the base substrate 110 is located between the wall 132 and the display area 112. The orthogonal projection is covered by the orthogonal projection of the organic sealing layer 124 on the base substrate 110 and includes a plurality of first A base substrate 1 of at least one first channel line 140 of the channel lines 140 The orthogonal projection at 10 is located on the side of the first edge 162 away from the viewing area 112 .

[0043] In the array substrate according to the embodiment of the present disclosure, the flat layer 160 is not provided over the entire layer. Therefore, the distance between the encapsulation layer 120 and the base substrate 110 decreases abruptly at the first edge 162. The organic encapsulation layer 124 also undergoes a leveling process, which causes the periphery region 114 to A first inclined portion 1243 is formed, the thickness of which is gradually decreased, and the first edge 16 of the organic sealing layer 124 is formed. The portion above the first channel 1241 is a first flat portion 1241. At least one first channel line 140 of the panel lines 140 is indicated by a first edge 162. The side away from the area 112 (i.e., the first inclined portion 1243 or the display area of ​​the first inclined portion 1243) By installing the first channel 1241 on the first flat portion 1241 (the side away from the area 112), The number of channel lines can be reduced, and the first channel line can be provided on the first flat portion 1241. This reduces the width of the first flat portion 1241 and further reduces the width of the peripheral region 114. As a result, the array substrate can be used in a display device that employs the array substrate. This helps to realize a narrow frame or frameless design.

[0044] For example, the display area may be the screen display area of ​​the array substrate, i.e., the light-emitting area. The peripheral area is an area where the screen of the array substrate does not display anything, i.e., a non-light-emitting area. The peripheral region may surround the display region or may be located at a portion of the periphery of the display region. good.

[0045] For example, the base substrate 110 may be a flexible base substrate 110, such as polyimide (po lyimide, PI) to form a flexible display device. The material of the flexible base substrate 100 is not limited to polyimide.

[0046] In some examples, as shown in FIGS. 3 and 4, the organic sealing layer 124 is The second edge 1242 includes a second edge 1242 extending from the first edge 162 to the first stop. At least one of the first channel lines 140 is located between the wall portion 132 and the The orthogonal projection of the first channel line 140 on the base substrate 110 is the second edge 1242 of the base substrate 110. The array substrate is located within an orthogonal projection on the plate 110. Thus, the array substrate is provided with a plurality of first channels. At least one of the first channel lines is located on the second edge to form a first flat The number of first channel lines installed on the first flat portion can be reduced, and No channel line is provided, thereby reducing the width of the first flat portion and further reducing the width of the peripheral region. can be reduced.

[0047] In some examples, as shown in FIGS. 3 and 4, the first channel lines 140 include A plurality of first flat channel lines 111 located on the side of the first edge 162 away from the base substrate 110 42 and a plurality of first inclined channels located on the side of the second edge 1242 away from the base substrate 110. A typical channel line includes a first edge of the base substrate and a second edge of the channel line. Since the sensor is installed on the far side, i.e., the first flat portion, the width of the first flat portion in the second direction Y is large. However, the first flat channel line in the array substrate according to the embodiment of the present disclosure is formed on the first edge of the substrate. The first slanted channel line is formed on the side away from the base substrate at the second edge. The first flat portion is formed on the far side of the first channel line that needs to be supported by the first flat portion. The number of the first flat portions can be reduced, thereby reducing the width of the first flat portion in the second direction Y. In addition, the width of the peripheral region of the array substrate in the second direction Y can be reduced. A display device employing the array substrate can have a narrow frame.

[0048] In some examples, as shown in FIG. 3 and FIG. 4, two adjacent first inclined channel lines The spacing between 144 is greater than the spacing between two adjacent first flat channel lines 142. A patterning process is performed on the conductive film layer so that the first slanted channel line is formed on the slanted surface. In the process of forming the first flat channel line and the first inclined channel line, If the performance of is limited, it is easy to cause underexposure of the first inclined channel line on the slope, Furthermore, a short circuit occurs between two adjacent first inclined channel lines. In the substrate, the distance between two adjacent first inclined channel lines is set to be equal to the distance between two adjacent first inclined channel lines. By setting the spacing between the flat channel lines larger than 1, the array substrate has a first tilt Various defects such as short circuits caused by insufficient exposure of the diagonal channel lines can be avoided.

[0049] In some examples, the spacing between two adjacent first inclined channel lines 144 is The distance between the two first flat channel lines 142 is 1.05 to 2 times the distance between the two first flat channel lines 142. The array substrate avoids the exposure problem by forming a first inclined channel line on the first inclined portion. This can avoid various defects due to exposure problems.

[0050] For example, the spacing between two adjacent first inclined channel lines 144 is 1.5 times the spacing between the flat channel lines 142. On the other hand, the array substrate The exposure problem caused by forming the first inclined channel line on the first inclined portion can be avoided, On the other hand, the array substrate further comprises a space between two adjacent first oblique channel lines. Since it can be made smaller, more first inclined channel lines are installed in the first inclined section. .

[0051] Of course, embodiments of the present disclosure include, but are not limited to, two adjacent The distance between the first inclined channel lines is the distance between two adjacent first flat channel lines. For example, the spacing between two adjacent first inclined channel lines may be equal to The distance between the first flat channel lines may be equal to the distance between the first slanted channel lines. The line width is greater than the line width of the first flat channel line. In some examples, the first sloping channel lines In the channel lines 144, the distance between two adjacent first inclined channel lines 144 is The width is 1.05 to 2 times the width of the first inclined channel line 144. Since the interval between the channel lines is set large, the array substrate has a first inclined channel on the first inclined portion. This avoids the exposure problem caused by forming channel lines, Therefore, various defects caused by the above-mentioned problems can be avoided.

[0052] In some examples, as shown in FIGS. 3 and 4, among the first channel lines 140 The first channel line 148, which is the furthest from the display area 112, is a part of the ground line. , and one of the first channel lines 140 that is farthest from the display area 112 The orthogonal projection of the channel lines 148 on the base substrate 110 is the same as that of the organic encapsulation layer 124 on the base substrate 110. 10 and the orthogonal projection of the first stop wall portion 132 on the base substrate 110. That is, the outermost one of the first channel lines is connected to ground. A portion of the wire and a ground wire are disposed between the first stop wall and the organic encapsulation layer. Thereby, the array substrate further utilizes the space between the first stop wall portion and the organic sealing layer. The ground line can be placed by increasing the number of channel lines on the flat portion of the encapsulation layer. Further reducing the width of the peripheral region of the array substrate.

[0054] For example, the touch driving electrodes and the touch sensing electrodes are transparent electrodes or metal meshes. The touch driving electrode and the touch sensing electrode may be provided with a capacitor at an overlapping position. When a finger touches the capacitor, it affects the coupling of the capacitor near the touch point. This changes the capacitance of the capacitor near the touch point. The change in capacitance can be used to determine the touch position. For example, the touch layer may include a mutual capacitance type touch structure, a self-capacitance type touch structure, and the like. The touch sensor may include a volumetric touch structure.

Since the flat layer 160 is not installed over the entire layer, the distance between the sealing layer 120 and the base substrate 110 The thickness of the organic encapsulation layer 124 decreases abruptly at the third edge 164 and the organic encapsulation layer 124 undergoes a leveling process. As a result, a second inclined portion 1247 whose thickness is gradually reduced is formed in the peripheral region 114.

For example, the touch driving signal line 186 and the touch sensing signal line 188 are both peripheral The region 114 extends to a binding region 115 for binding to an external circuit. Thus, touch driving, data reception and data processing can be realized. The touch sensing electrode 184 extends along the first direction and includes a plurality of touch sensing electrodes 18 4 is arranged along the second direction, and at least a part of the plurality of first channel lines 140 The first channel line 140 is a part of the touch sensing signal line 188, The touch drive electrode 182 extends along the second direction, and the plurality of touch drive electrodes 182 are At least some of the second channel lines 190 are arranged along the direction The touch line 190 is part of the touch drive signal line 186.

The second portion 1862 is connected to the first portion 1861, and the third portion 1863 is connected to the 2 part 1862. At that time, the extension direction of each touch drive electrode 182 is a first direction The arrangement direction of the plurality of touch driving electrodes 182 is the second direction Y. The panel line 140 may be a third portion 1863 of the touch drive signal line 186.

At least one of the second channel lines 190 is located between the stop wall 134 and the The orthogonal projection of one second channel line 190 on the base substrate 110 is the base of the fourth edge 1245. The array substrate 110 is located within an orthogonal projection of the second channel lines 19. 10, the orthogonal projection of at least one second channel line 190 on the base substrate 110 is 4. The edge 1245 is placed within an orthogonal projection on the base substrate 110 (i.e., a plurality of second channels). At least one second channel line 190 of the panel lines 190 is provided on the fourth edge 1245. By placing the second flat portion 1246 on the second flat portion 1246, the number of second channel lines placed on the second flat portion 1246 is reduced. , or the second channel line is not provided on the second flat portion 1246, so that the second flat portion 124 6 and further reduce the width of the peripheral region 114.

As a result, a display device using this array substrate can have a narrow frame.

[0062] In some cases, as shown in FIGS. 3 and 5, two adjacent second inclined channel lines The spacing between 194 is greater than the spacing between two adjacent second flat channel lines 192. A patterning process is performed on the conductive film layer so that the second slanted channel line is formed on the slanted surface. In the process of forming the second flat channel line and the second inclined channel line, If the performance of is limited, it is easy to cause underexposure of the second inclined channel line on the slope, Furthermore, a short circuit occurs between two adjacent second inclined channel lines.

The array substrate avoids the exposure problem by forming a second inclined channel line on the second inclined portion. This can avoid various defects due to exposure problems.

[0064] For example, the spacing between two adjacent second inclined channel lines 194 is 1 / 2 the spacing between two adjacent first inclined channel lines 194. The distance between the two flat channel lines 192 is 1.5 times the distance between the two flat channel lines 192. 2.

[0068] For example, the material of the first inorganic sealing layer and the second inorganic sealing layer may be silicon oxide, silicon nitride or The inorganic material can be selected from one or more silicon oxynitrides. Therefore, it is possible to prevent water, oxygen, etc. from entering the light emitting element and affecting its performance. The material of the organic sealing layer is a polymer resin, such as polyimide or polyacrylic ester. The organic sealing layer has functions such as planarization and stress relaxation.

Since the difference between d1 and d2 is large and is equal to or greater than the thickness of the flat layer 160, the first inorganic sealing The organic sealing layer 124 formed on the layer 122 has a thickness that gradually decreases at the position of the second inorganic sealing portion 1222. That is, the second organic sealing portion 1249 is a sloped portion, and the first organic sealing portion 1249 is a sloped portion. The sealing portion 1248 is a flat portion. At least one of the first channel lines 140 is orthogonally projected onto the base substrate 110 by a second optical fiber. In the orthogonal projection of the organic encapsulation portion 1222 on the base substrate 110 (i.e., the second organic encapsulation portion 1249 or By inserting the second organic sealing portion 1249 (the side away from the display region 112), The number of first channel lines disposed on the flat portion of the encapsulation layer 124 can be reduced, or The first channel line is not provided on the flat portion of the organic sealing layer 124, so that the organic sealing layer 124 The width of the flat portion of the periphery region 114 can be reduced, and the width of the peripheral region 114 can be reduced. As a result, the array substrate can be designed to have a narrow frame or even a frameless display device using the array substrate. This helps to achieve the above.

The encapsulation layer 120 may include a circuit structure that drives the light emitting structure so that the light emitting structure emits light. The light emitting structure and the circuit structure formed on the base substrate 110 are sealed to prevent damage to the external environment. The first stopper prevents corrosion of the light-emitting structure and the circuit structure caused by water and oxygen. The first stop wall 130 is disposed on the base substrate 110 and is located in the peripheral region 114. The top wall 130 is formed so that the fluid material in the sealing layer 120 flows into the first stop during the formation of the sealing layer 120. The plurality of first channel lines 14 can be prevented from flowing out of the cup wall 130. 0 is located in the peripheral region 114 and on the side of the sealing layer 120 away from the base substrate 110. Place it.

[0083] As shown in FIGS. 9 and 10, each of the first channel lines 140 extends along a first direction X. The first channel lines 140 are arranged along the second direction Y, and the first stop wall 1 30 includes a first stop wall 132 extending along a first direction X. The sealing layer 120 includes: The organic sealing layer 124 includes an organic sealing layer 124, and an edge portion of the organic sealing layer 124 extending along the first direction X is a first Located between the stop wall 132 and the display area 112, the edge has a first flat portion 1241 and The first channel lines 140 include a first inclined portion 1243. At least a portion of the first channel lines 140 It should be noted that the slope of the first flat portion is less than 1 / 50. The first inclined portion has a gradient greater than 1 / 50. At least a part of the first channel lines is located on the first inclined portion. This means that the projection and the orthogonal projection of the first inclined portion on the base substrate overlap at least locally.

[0084] In the array substrate according to the embodiment of the present disclosure, the organic sealing layer undergoes a leveling process. The array substrate includes a first inclined portion having a thickness gradually decreasing in a peripheral region. By placing the channel line at least locally on the first inclined portion, the array substrate has: The width of the peripheral region can be reduced, thereby improving the overall appearance of the display device employing the array substrate. The frame width can be reduced, thereby enabling a narrow frame design.

[0085] In some examples, as shown in FIGS. 9 and 10, the organic sealing layer 124 is The second edge 1242 extends along the first inclined portion 1243. 42 is located between the first edge 162 and the first stop wall 132 and includes a plurality of first channels At least one of the first channel lines 140 is a positive lead on the base substrate 110. The shadow is located within the orthogonal projection of the second edge 1242 on the base substrate 110. The layout substrate includes a plurality of first channel lines at least locally disposed on the second edge portion. Therefore, the number of first channel lines installed on the first flat portion can be reduced, and the first The first channel line is not provided on the flat portion, thereby reducing the width of the first flat portion and further reducing the circumference. The width of the border region can be reduced.

[0086] In some examples, as shown in FIGS. 9 and 10, the first channel lines 140 include: A plurality of first flat channel lines 142 located on the first flat portion 1241 and the first inclined portion 124 3. That is, the plurality of first flat channel lines 144 are disposed at the first flat channel lines 144. The orthogonal projection of the channel line 142 on the base substrate 110 is 10, the orthogonal projection of the first plurality of inclined channel lines 144 on the base substrate 110. The projection is within the orthogonal projection of the first inclined portion 1243 on the base substrate 110. In the typical design, the first channel lines are all installed on the first flat portion. The width of the first flat portion in the second direction Y is large, but the first flat portion in the array substrate according to the embodiment of the present disclosure A flat channel line is formed in the first flat portion and a first inclined channel line is formed in the first inclined portion. This significantly reduces the number of first channel lines that the first flat portion needs to support, and This can reduce the width of the first flat portion in the second direction Y. The width of the peripheral region in the second direction Y can be reduced. The display device used may have a narrow frame.

[0087] In some examples, as shown in FIGS. 9 and 10, two adjacent first inclined channels The spacing between the lines 144 is greater than the spacing between two adjacent first flat channel lines 142. Since the first slanted channel line is formed on the slanted surface, a patterning process is performed on the conductive film layer. In the process of forming the first flat channel line and the first inclined channel line, If the machine's performance is limited, it is easy to cause underexposure of the first inclined channel line on the slope. As a result, a short circuit occurs between two adjacent first inclined channel lines. In the array substrate, the distance between two adjacent first inclined channel lines is set to be equal to or smaller than the distance between two adjacent first inclined channel lines. By setting the spacing between the first planar channel lines larger than the spacing between the first planar channel lines, the array substrate Various defects such as short circuits caused by insufficient exposure of the first gradient channel line can be avoided.

[0088] In some examples, the spacing between two adjacent first inclined channel lines 144 is The distance between the two first flat channel lines 142 is 1.05 to 2 times the distance between the two first flat channel lines 142. The array substrate avoids the exposure problem by forming the first inclined channel line on the first inclined portion. This can avoid various defects due to exposure problems.

[0089] In some examples, as shown in FIGS. 9 and 10, two adjacent first inclined channels The spacing between the lines 144 is 1.5 times the spacing between two adjacent first flat channel lines 142. The distance between two adjacent first inclined channel lines is set to be equal to or greater than the distance between two adjacent first inclined channel lines. By setting the spacing between the flat channel lines at 1.5 times or more, the array substrate 1. The exposure problem caused by forming the inclined channel line on the first inclined portion can be avoided, This makes it possible to avoid various defects caused by exposure problems.

[0090] For example, a first sloped channel line is formed in the first sloped portion, so that the conductive film layer is patterned. The process for forming the first flat channel line and the first inclined channel line is performed as follows: In this case, if the performance of the exposure machine is limited, it may cause insufficient exposure of the first inclined channel line. This causes a short circuit between two adjacent first inclined channel lines. In the array substrate according to the present invention, the distance between two adjacent first inclined channel lines is set to be equal to or larger than the distance between adjacent first inclined channel lines. By setting the distance between the first two flat channel lines to 1.5 times or more, the array The substrate can avoid a short circuit caused by insufficient exposure of the first inclined channel line.

[0091] In some examples, the first inclined channel lines 144 may include adjacent first inclined channel lines 144. The spacing between the inclined channel lines 144 is 1.05 to 2 times the width of the first inclined channel line 144. The distance between the two adjacent first inclined channel lines is set large, so that the The array substrate avoids the exposure problem by forming the first inclined channel line on the first inclined portion. This makes it possible to avoid various defects due to exposure problems.

[0092] In some examples, as shown in FIGS. 9 and 10, among the plurality of first inclined channel lines , the interval between two adjacent first inclined channel lines 144 is The width of the first inclined channel is 1.5 times the width (i.e., line width) of the first inclined channel. By setting the distance between the channel lines large, the first inclined channel line is This avoids the exposure problems caused by forming the Defects can be avoided.

[0093] In some examples, as shown in FIGS. 9 and 10, the first inclined portion 1243 and the first flat portion 1241 are continuously arranged along the second direction Y, and the first inclined portion 1243 is a first flat portion 1241 on the side closer to the first stop wall portion 132. That is, the first inclined portion and the first The flat portion is a first edge extending along a first direction X, the first edge being formed by leveling the organic sealing layer. The two parts are consecutive parts of the same part.

[0094] In some examples, as shown in FIGS. 9 and 10, the first channel lines 140 That is, the first channel line 140 that is the furthest from the display area 112 is the surface of the first inclined portion 1243. 12. The edge of the display area 112 is located at a position above the first inclined portion 1243. All of the first channel lines 140 (i.e., the first inclined channel lines 144) are provided. This allows the width of the peripheral region of the array substrate to be significantly reduced, This helps to realize a narrow frame design.

[0095] In some examples, as shown in FIG. 10, the sealing layer 120 includes a first inorganic sealing layer 122 and a second inorganic sealing layer 123. The first inorganic sealing layer 122 is disposed on the base substrate 110. The second inorganic sealing layer 126 is formed on the side of the first inorganic sealing layer 122 that is away from the base substrate 110. The organic sealing layer 124 is formed by bonding the first inorganic sealing layer 122 and the second inorganic sealing layer 124 together. This allows the sealing layer to have a strong ability to isolate water and oxygen, This effectively prevents water and oxygen from the external environment from corroding the device encapsulated in the encapsulation layer. It is possible.

[0096] For example, the material of the first inorganic sealing layer and the second inorganic sealing layer may be silicon oxide, silicon nitride or The material of the organic sealing layer may be selected from one or more of organic resins, silicon oxynitrides, and silicon oxynitrides. It may be fat.

[0097] In some examples, as shown in FIG. 9 and FIG. 10, the array substrate 100 has a plurality of touch panels. A touch driving electrode 182, a plurality of touch sensing electrodes 184, and a touch driving signal line 186. , and a touch sensing signal line 188. The touch sensing electrodes 184 are all located in the display area 112 and are formed on the sealing layer 120. The touch drive signal line 186 is located on the side away from the base substrate 110. The touch sensing signal line 18 is connected to the electrode 182 and extends to the peripheral region 114. 8 is connected to each touch sensing electrode 184 and extends to the peripheral region 114. For example, the touch driving signal line 186 and the touch sensing signal line 188 are both in the peripheral region. 114 to a binding region 115 for binding to an external circuit, This allows touch driving, data reception and data processing to be realized. In the array substrate, each of the plurality of first channel lines 140 is a touch driving signal line 186 or This is part of the touch sensing signal line 188.

[0098] For example, as shown in FIGS. 9 and 10, the touch drive signal line 186 is 82 and the arrangement of the plurality of touch drive electrodes 182. A second portion 1862 extending along the column direction and a second portion 1863 extending along the extension direction of the touch drive electrode 182 The first portion 1861 is connected to the touch drive electrode 182. The second portion 1862 is connected to the first portion 1861, and the third portion 1863 is connected to the second portion At that time, the extension direction of each touch drive electrode 182 is the first direction X. The arrangement direction of the plurality of touch driving electrodes 182 is the second direction Y. The line 140 may be a third portion 1863 of the touch drive signal line 186.

At this time, the extension direction of each touch sensing electrode 184 is the second direction Y. The arrangement direction of the plurality of touch sensing electrodes 184 is the first direction X. The touch sensing signal line 188 may be a fifth portion 1882 of the touch sensing signal line 188. At this time, some of the first channel lines 140 are part of the touch driving signal lines 186, and some of the second channel lines 140 are part of the touch driving signal lines 186. The 1 channel line 140 is part of the touch sensing signal line 188 .

[0100] FIG. 11 is a schematic cross-sectional view of an array substrate according to an embodiment of the present disclosure taken along the FF direction in FIG. As shown in FIGS. 9, 10, and 11, the first stop wall 130 is For example, the second stop wall 134 may extend beyond the first stop wall 134. Two first stop walls 132 and two second stop walls 132 are connected to the top wall 132. 134 are interconnected to form a rectangular first stop wall 130 that surrounds the display area 112 .

[0101] In some examples, as shown in FIG. 11, the array substrate 100 includes a plurality of second channels. Each of the second channel lines 190 extends along the second direction. The edge of the sealing layer 124 extending along the second direction is connected to the second stop wall 134 and the display area 136. 112. The edge includes a second flat portion 1246 and a second inclined portion 1247. At least a portion of the second channel lines 190 is located on the second inclined portion 1247. That is, the orthogonal projection of the second channel lines 190 on the base substrate 110 is formed at a second inclination. The oblique portion 1247 at least partially overlaps with the orthogonal projection on the base substrate 110. In the array substrate, the organic sealing layer undergoes a leveling process, which causes the peripheral area The second inclined portion is formed on the second channel line. At least a part of the second channel line has the second inclined portion. By being disposed in the portion, the array substrate reduces the width of the peripheral region in the first direction.

[0102] In some examples, as shown in FIG. 11, the plurality of second channel lines 190 may include a second planar a second flat channel line 192 located at a second inclined portion 1247; and a plurality of second inclined channel lines 194. That is, a plurality of second flat channel lines The orthogonal projection of the line 192 on the base substrate 110 is the second flat portion 1246 on the base substrate 110. In the orthogonal projection, the orthogonal projection of the second plurality of inclined channel lines 194 on the base substrate 110 is: The second inclined portion 1247 is projected onto the base substrate 110. In the above, since the plurality of second channel lines are all installed on the second flat portion, The width in the first direction X of the second flat channel line in the array substrate according to the present embodiment is large. A second inclined channel line is formed in the second inclined portion, thereby forming a second The number of secondary channel lines that the flat section must support is greatly reduced, thereby The width of the support portion in the first direction X can be reduced, and the first The width in the direction can be reduced. As a result, the display device using the array substrate can , may have narrow picture frames.

By setting the distance between the second inclined channels to 1.5 times or more, the array substrate The exposure problem caused by forming the channel line on the second inclined portion can be avoided, thereby This can avoid various defects caused by exposure problems.

[0104] For example, a second sloped channel line is formed in the second sloped portion, so that the conductive film layer is patterned. The process for forming the second flat channel line and the second inclined channel line is performed. In this case, if the performance of the exposure machine is limited, it may cause insufficient exposure of the second inclined channel line. This causes a short circuit between two adjacent second inclined channel lines. In the array substrate according to the present invention, the interval between two adjacent second inclined channel lines is set to be equal to or larger than the interval between adjacent second inclined channel lines. By setting the distance between the two second flat channel lines to 1.5 times or more, the array The substrate can avoid the short circuit phenomenon caused by insufficient exposure of the second inclined channel line.

In other words, the upper position of the second inclined portion 1247 is To install the second channel line 190 (i.e., the second inclined channel line 194), This allows the width of the peripheral area of ​​the array substrate to be significantly reduced, This helps to achieve a narrower frame design.

At that time, the extension direction of each touch drive electrode 182 is The direction of the touch driving electrodes 182 is the first direction X, and the direction of arrangement of the touch driving electrodes 182 is the second direction Y. The channel line 190 may be a second portion 1862 of the touch drive signal line 186.

The organic light emitting element 170 is located in the display area 112 and is sandwiched between the sealing layer 1 and the display area 112. 20 and the base substrate 110. At that time, the encapsulation layer 120 is disposed between the organic light emitting element 17 and the base substrate 110. By sealing the organic light emitting element 170, water and oxygen in the external environment are prevented from corroding the organic light emitting element 170. It can be prevented.

[0112] 12 is a schematic plan view of another array substrate according to an embodiment of the present disclosure. 13 is a schematic cross-sectional view of an array substrate according to an embodiment of the present disclosure taken along the direction GG in FIG. 12. As shown in FIGS. 12 and 13, the array substrate 100 further includes a second stop wall 230. The second stop wall 230 is disposed on the base substrate 110 and is located in the peripheral region 114. The second stop wall 230 is located between the first stop wall 130 and the display area 112. The second stop wall 230 includes a third stop wall portion 232 extending along the first direction. , the orthogonal projection of the first channel lines 140 on the base substrate 110 is formed by the third stop wall portion 2 32 on the base substrate 110. That is, the first At least a portion of the channel line 140 is disposed in the third stop wall portion 232. At this time, at least a portion of the first channel wires is installed in the third stop wall portion. Thus, the array substrate can further reduce the width of the peripheral region, thereby The frame width of the display device using the array substrate can be further reduced, thereby Achieves a narrow frame design.

[0113] It should be noted that the first channel lines are at least partially connected to the third stop wall. When installed, the first inorganic sealing layer and the second inorganic sealing layer of the sealing layer are disposed on the base of the third stop wall portion. The first channel may be disposed on a side away from the base substrate, and the third stop wall may be disposed on the first channel.

A stop wall channel line is formed in the third stop wall portion, which provides support for the first flat portion. The number of first channel lines that need to be connected in the second direction Y of the first flat portion is significantly reduced, thereby The width of the peripheral region of the array substrate in the second direction Y can be significantly reduced. As a result, the display device using the array substrate can have a narrow frame. may have the following structure:

As shown in FIG. 14, the second stop wall 230 is a second stop wall extending along the second direction. The four-stop wall 234 is provided to prevent the second channel lines 190 from being pushed out from the base substrate 110. The projection at least locally overlaps with the orthogonal projection of the fourth stop wall 234 on the base substrate 110. That is, at least a part of the second channel lines 190 is connected to the fourth stop. At that time, the plurality of second channel lines are at least locally connected to the fourth slot. By mounting on the top wall, the array substrate can further reduce the width of the peripheral area. This allows the frame width of a display device using the array substrate to be further reduced. This allows for a narrow frame design.

[0116] In some examples, as shown in FIG. 14, the plurality of second channel lines 190 may include a fourth The stop wall includes a plurality of second stop wall channel lines 196 located in the stop wall portion 234. , the orthogonal projection of the plurality of second stop wall channel lines 196 on the base substrate 110 is The orthogonal projection of the cap wall 234 on the base substrate 110 is included in the embodiment of the present disclosure. A second flat channel line in the array substrate is formed on the second flat portion, and a second oblique channel is formed on the second flat portion. The second stop wall channel line is formed in the second slope portion and the second stop wall channel line is formed in the fourth stop wall portion. This significantly reduces the number of second channel lines that the second flat portion needs to support, This allows the width of the second flat portion in the first direction X to be reduced, and the array substrate The width of the peripheral region in the first direction X can be reduced. The display employed may have a narrow bezel.

[0117] An embodiment of the present disclosure further provides an array substrate. As shown in FIG. 15, the array substrate is a base substrate 110. a pixel driving layer 150, an organic light emitting element 170, a sealing layer 120, and a plurality of first channels. The base substrate 110 includes a display area 112 and a wiring 140. The pixel driving layer 150 is located on the base substrate 110. The light emitting element 170 is located on the side of the planar layer 160 away from the pixel driving layer 150. The first light emitting element 120 is disposed on the side of the organic light emitting element 170 that is away from the base substrate 110. The channel lines 140 are located in the peripheral region 114 and are connected to the base substrate 110 of the encapsulation layer 120. Each of the first channel lines 140 extends along a first direction X and includes a plurality of The first channel lines 140 are arranged along a second direction Y, and the second direction Y is perpendicular to the first direction X. It should be noted that the pixel driving layer is substantially perpendicular to the corresponding organic light emitting element. The pixel circuit may include a pixel circuit for driving the pixel circuit to emit light. A direction is perpendicular to a first direction if the angle between the first direction and the second direction is equal to 90 degrees. , when the included angle between the first direction and the second direction is greater than 80 degrees and less than 100 degrees; This includes:

[0118] As shown in FIG. 15, the sealing layer 120 is made up of a first inorganic sealing layer 122 and an organic sealing layer 123 which are disposed in sequence. In the peripheral region 114, the display region 112 is provided with a stop layer 124.

Therefore, the distance between the first organic sealing portion 1241 and the base substrate 110 is suddenly reduced. The organic encapsulation layer 124 undergoes a leveling process, so that the second organic encapsulation portion 1242 is A first inclined portion 1243 whose thickness gradually decreases is formed in the region 114. The base of at least one of the first channel lines 140 The orthogonal projection on the substrate 110 is the orthogonal projection of the second inorganic sealing portion 1222 on the base substrate 110 (i.e., That is, the first inclined portion 1243 or the side of the first inclined portion 1243 away from the display area 112 By this, the first channel line provided on the relatively flat first organic sealing portion 1241 The number of the first channel lines can be reduced, and the first organic sealing portion 1241 can be provided with the first channel lines. This reduces the width of the first organic sealing portion 1241 and further reduces the width of the peripheral region 114. As a result, the array substrate can be used in a display device that employs the array substrate. This helps to realize a narrow frame or frameless design.

[0120] In some instances, the array substrate may be flush with the first stop wall 130, as shown in FIG. The pixel driving layer 150 further includes a flat layer 160. The flat layer 160 is formed from the base substrate 110 of the pixel driving layer 150.
