Description

Technical Field

[0001] The present disclosure belongs to the field of display technology, and particularly relates to a display substrate and a display device. Background Art

[0002] Organic Light-Emitting Diode (OLED) and Quantum Dot Light Emitting Diode (QLED) panels generally use Chemical Vapor Deposition (CVD) to form an encapsulation layer to protect the light-emitting devices therein to ensure that the light-emitting devices do not undergo oxidation reactions with the outside world.

[0003] However, if the encapsulation fails, such as when the encapsulation layer breaks or cracks, moisture can enter the interior of the OLED or QLED panel through the gaps, causing the organic light-emitting layer of the light-emitting device to oxidize and fail, rendering it unable to emit light normally. As moisture continues to enter, more and more light-emitting devices will fail to emit light normally, and the OLED or QLED panel will experience expanding dark spots, affecting the display quality.

[0078] In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the present disclosure is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0080] Figure 1 is a schematic structural diagram of an exemplary display substrate. Figure 2 for Figure 1 The enlarged structural diagram of the corner area in the display substrate is shown in FIG. Figure 1 and Figure 2 As shown, the display substrate has a display area 10 and a non-display area 20 surrounding the display area 10. The display substrate includes: a base 101, a blocking structure 200 and an intercepting structure 300 located on the base 101 and disposed in the non-display area 20; the blocking structure 200 is closer to the display area 10 than the intercepting structure 300; the display substrate also includes: a first conductive layer 102, a second conductive layer 103, and an anode conductive layer 104 located on the base 101 and disposed in sequence away from the base 101. The first conductive layer 102 and the second conductive layer 103 can form film layers for each thin-film transistor device in the display area 10, and can also form signal lines connecting the thin-film transistors and light-emitting devices in the display area 10. The anode conductive layer 104 can form the anode of each light-emitting device in the display area 10.

[0081] It should be noted that the above-mentioned display substrate and the subsequent description are explained using the OLED display substrate as an example. Of course, the above-mentioned display substrate can also be a QLED display substrate. The implementation principle is basically the same and will not be repeated.

[0082] The first conductive layer 102 and the second conductive layer 103 can extend from the display area 10 into the non-display area 20. Specifically, the first conductive layer 102 and the second conductive layer 103 can be power supply voltage lines, such as a low-level power supply voltage line VSS. It is understood that the first conductive layer 102 and the second conductive layer 103 can also be other types of signal lines, which are not listed here. In the embodiments of this disclosure and the subsequent description, the low-level signal line VSS will be used as an example. The blocking structure 200 and the intercepting structure 300 are both made of organic materials. Specifically, the blocking structure 200 includes a first blocking dam 201 and a second blocking dam 202.

[0083] In conventional display substrates, two insulating layers are provided between the first conductive layer 102 and the second conductive layer 103, one of which is an organic insulating layer and the other is an inorganic insulating layer. Currently, to reduce manufacturing costs and increase the production capacity of display substrates, the inorganic insulating layer is often eliminated, meaning that only one organic insulating layer is provided between the first conductive layer 102 and the second conductive layer 103. In the non-display area 20, to reduce the impedance of the signal line, the low-level power line VSS is generally made of a double conductive layer. However, after the inorganic insulating layer is eliminated, in the fan-out area 20a, if only the first conductive layer 102 is used to pass through the blocking structure 200 and the intercepting structure 300 to connect to the driver chip, the second conductive layer 103 needs to be cut off in the corner area 20b. Since the first conductive layer 102 and the second conductive layer 103 are made of the same material, the exposed first conductive layer 102 will be etched away when the second conductive layer 103 is etched, affecting the circuit structure. Furthermore, the second conductive layer 103 is formed after the first conductive layer 102, so there are fewer subsequent processes, and the etching depth of the second conductive layer 103 is smaller than that of the first conductive layer 102. Therefore, only one layer of the second conductive layer 103 must be used to pass through the blocking structure 200 and the intercepting structure 300 to connect to the driver chip.

[0084] When only the second conductive layer 103 is used to connect the driver chip, the first conductive layer 102 needs to shrink from the position of the intercepting structure 300 to the display area 10 to be cut off at the fan-out area 20a, ensuring that only the second conductive layer 103 passes through the blocking structure 200 and the intercepting structure 300 at the fan-out area 20a. Since the first conductive layer 102 is often covered with an organic material layer, a water vapor channel (indicated by the arrow in the figure) is easily formed at the position where the first conductive layer 102 shrinks toward the display area 10, that is, at position 1 and position 2. Specifically, the boundary line of the first conductive layer 102 is below the intercepting structure 300 and extends along the intercepting structure 300 to position 1; at position 1, the first conductive layer 102 shrinks from the intercepting structure 300 to the bottom of the second blocking dam 202 and extends along the second blocking dam 202 to position 3. At the same time, the anode conductive layer 104 shrinks from the second blocking dam 202 at position 2 to the side of the first blocking dam 201 close to the display area 10. At position 1, the first conductive layer 102 needs to be covered by an organic material layer between the intercepting structure 300 and the second barrier dam 202. At position 2, the anode conductive layer 104 shrinks from the second barrier dam 202 to the inside of the first barrier dam 201 and is covered by the pixel defining layer. The first conductive layer 102 shrinks from the second barrier dam 202 to below the first barrier dam 201 and extends along the first barrier dam 201 to position 3, ultimately shrinking to the display area 10. At position 3, to reduce the water vapor path, the first conductive layer 102 is not covered by the organic material layer. It can be seen that at both positions 1 and 2, the first conductive layer 102 shrinks using the shortest path, forming a water vapor path between positions 1 and 2. If the encapsulation fails, such as when the encapsulation layer breaks or cracks, water vapor can enter the interior of the display substrate through the gaps and water vapor path, causing the organic light-emitting layer of the light-emitting device to oxidize and fail, preventing normal light emission. As water vapor continues to invade, more and more light-emitting devices will be unable to emit light normally, and the OLED panel will have the defect of continuously expanding dark spots, affecting the display effect.

[0085] Figure 3 for Figure 2 The cross-sectional structure diagram of the display substrate at position 3 along the AA' direction is shown in FIG. Figure 3 As shown, at position 3, the first conductive layer 102 is cut off, but the second conductive layer 103 is still continuously provided. At this time, the second conductive layer 103 is prone to breakage at this position. Since there is no anode conductive layer 104 covering this position, a step difference is easily formed here, and the encapsulation layer thereon is prone to cracks at the break, resulting in encapsulation failure, allowing water vapor to enter the interior of the display substrate through the water vapor channel, causing the organic light-emitting layer of the light-emitting device to oxidize and fail to emit light normally.

[0086] In order to solve at least one of the above technical problems, the embodiments of the present disclosure provide a display substrate and a display device. The display substrate and the display device provided by the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0087] Figure 4a A schematic structural diagram of a display substrate provided in an embodiment of the present disclosure is shown. Figure 5a for Figure 4a The enlarged structural diagram of the corner area in the display substrate shown in FIG. 1 is a schematic diagram of the enlarged structural diagram of the corner area in the display substrate shown in FIG. 1 . It can be understood that the embodiment of the present disclosure Figure 5a Only the structure of the lower left corner area of ​​the display substrate is shown in the figure. The structure of the lower right corner area is similar to that of the lower left corner area. The embodiment of the present disclosure will be described based on the structure of the lower left corner area of ​​the display substrate. Figure 4a and Figure 5a As shown, the display substrate provided by the embodiment of the present disclosure has a display area 10 and a non-display area 20 surrounding the display area 10, and the display substrate includes: a base 101, a blocking structure 200 located on the base 101 and arranged in the non-display area 20; the display substrate also includes: a first conductive layer 102, a second conductive layer 103, and an anode conductive layer 104 located on the base 101 and arranged in sequence along a direction away from the base 101; the first conductive layer 102 has a first boundary line 1021; the anode conductive layer 104 has a second boundary line 1021 substantially parallel to the extension direction of the first boundary line Boundary line 1041 The second boundary line 1041 is located on the side of the first boundary line 1021 away from the display area 10; the non-display area 20 includes: a fan-out area 20a arranged on one side of the display area 10 and a corner area 20b connected to the fan-out area 20a; in the fan-out area 20a, the first conductive layer 102 is cut off and the second conductive layer 103 is continuously arranged; in the corner area 20b, the anode conductive layer 104 is cut off, and the orthographic projection of the blocking structure 200 on the substrate 101 at least partially covers the orthographic projection of the first boundary line 1021 and the second boundary line 1041 on the substrate 101.

[0088] For example, the substrate 101 can be made of a rigid material such as glass to improve the substrate 101's ability to support other film layers thereon. Alternatively, the substrate 101 can be made of a flexible material such as polyimide (PI) to improve the overall display substrate's resistance to bending and stretching, thereby preventing stress generated during bending, stretching, and twisting from causing the substrate 101 to break and cause a short circuit. In practical applications, the material of the substrate 101 can be appropriately selected based on actual needs to ensure that the display substrate has good performance.

[0089] The blocking structure 200 can be made of organic materials, such as polyimide, epoxy resin and other organic materials. At the same time, the blocking structure 200 can be made of a single-layer structure or a multi-layer structure. The blocking structure 200 can be formed in the non-display area 20 of the display substrate and surround the entire display area 10, so that cracks in the film layers such as the encapsulation layer in the display substrate caused by external forces are stopped at the position of the blocking structure 200, thereby preventing the cracks from extending from the non-display area 20 to the display area 10 and affecting the performance of the light-emitting device in the display area 10.

[0090] The first conductive layer 102 and the second conductive layer 103 can be made of the same conductive material, for example, aluminum, titanium, copper, molybdenum and other metal materials. At the same time, the first conductive layer 102 and the second conductive layer 103 can be made of a single layer structure or a multi-layer structure, for example, a three-layer metal layer structure of titanium / aluminum / titanium, molybdenum / aluminum / molybdenum, titanium / copper / titanium or molybdenum / copper / molybdenum. The first conductive layer 102 and the second conductive layer 103 can extend from the display area 10 to the non-display area 20. Specifically, the first conductive layer 102 and the second conductive layer 103 can form the film layer of the thin film transistor in the display area 10, and can also form a signal line for transmitting signals, such as a power supply voltage line. Specifically, the power supply voltage line can be a low-level power supply voltage line VSS. It is understandable that the first conductive layer 102 and the second conductive layer 103 can also be other types of signal lines, which are not listed here one by one. In the embodiment of the present disclosure and the subsequent description, the low-level signal line VSS will be used as an example for explanation.

[0091] In the fan-out region 20a, the first conductive layer 102 is cut off and disconnected, while the second conductive layer 103 is continuous and passes through the barrier structure 200. The second conductive layer 103 passes through the barrier structure 200 to connect to the driver chip. In the corner region 20b, the anode conductive layer 104 is cut off. The first conductive layer 102 has a first boundary line 1021, and the anode conductive layer 104 has a second boundary line 1041. In the corner region 20b, the second boundary line 1041 is located on the side of the first boundary line 1021 away from the display area 10. The orthographic projection of the barrier structure 200 on the substrate 101 at least partially covers the orthographic projections of the first boundary line 1021 and the second boundary line 1041 on the substrate 101. That is, the barrier structure 200 covers the second boundary line 1041 of the anode conductive layer 104, and the anode conductive layer 104 covers the first boundary line 1021 of the first conductive layer 102. It should be noted here that the first boundary line 1021 and the second boundary line 1041 are basically parallel. Basically parallel here means parallel within the allowable process error range. In the subsequent description, the meaning of basically parallel is the same and will not be described in detail.

[0092] In the display substrate provided by the embodiment of the present disclosure, the blocking structure 200 covers the second boundary line 1041 of the anode conductive layer 104, and the anode conductive layer 104 covers the first boundary line 1021 of the first conductive layer 102. Since the anode conductive layer 104 is generally covered with a pixel defining layer, it is not necessary to separately set an organic material layer to cover the second boundary line 1041 of the anode conductive layer 104 and the first boundary line 1021 of the first conductive layer 102. The first boundary line 1021 of the first conductive layer 102 and the second boundary line 1041 of the anode conductive layer 104 are both located below the blocking structure 200 and extend a distance toward the fan-out area 20a, that is, the first conductive layer 102 and the anode conductive layer 104 shrink toward the display area 10 together, and do not need to extend to the area outside the blocking structure 200. This can ensure that the grooves of the organic material layer are complete and avoid the formation of water vapor channels. Therefore, water vapor can be prevented from entering the display area 10 of the display substrate through the water vapor channels, causing the organic light-emitting layer of the light-emitting device to fail, thereby avoiding the occurrence of continuously expanding dark spots due to the failure of the organic light-emitting layer, thereby improving the display effect of the display substrate.

[0093] In some embodiments, as shown in FIG Figure 4a and 5a As shown, the blocking structure 200 includes: a first blocking dam 201 ; an orthographic projection of the first blocking dam 201 on the substrate 101 at least partially covers the orthographic projections of the first boundary line 1021 and the second boundary line 1041 on the substrate 101 .

[0094] The blocking structure 200 can be composed of a blocking dam, namely a first blocking dam 201. The first boundary line 1021 of the first conductive layer 102 and the second boundary line 1041 of the anode conductive layer 104 are both located below the first blocking dam 201 and extend a distance toward the fan-out area 20a. That is, the first conductive layer 102 and the anode conductive layer 104 shrink toward the display area 10 together and do not need to extend to the area outside the blocking structure 200. This can ensure that the grooves of the organic material layer are complete and avoid the formation of water vapor channels. Therefore, water vapor can be prevented from entering the display area 10 of the display substrate through the water vapor channels, causing the organic light-emitting layer of the light-emitting device to fail, thereby avoiding the occurrence of continuously expanding dark spots due to the failure of the organic light-emitting layer, thereby improving the display effect of the display substrate.

[0095] In some embodiments, as Figure 4b and Figure 5bAs shown, the first conductive layer 102 also has a third boundary line 1022 that is basically parallel to the extension direction of the first boundary line 1021; the third boundary line 1022 is located on the side of the first boundary line 1021 away from the display area 10; the anode conductive layer 104 also has a fourth boundary line 1042 that is basically parallel to the extension direction of the second boundary line 1041; the fourth boundary line 1042 is located on the side of the second boundary line 1041 away from the display area 10, and the fourth boundary line 1042 is located on the side of the third boundary line 1022 away from the display area 10.

[0096] The third boundary line 1022 of the first conductive layer 102 and the fourth boundary 1042 of the anode conductive layer 104 extend toward the fan-out area 20a for a distance and then shrink toward the first blocking dam 201. Thereafter, the third boundary line 1022 of the first conductive layer 102 is connected to the first boundary line 1021, the fourth boundary line 1042 of the anode conductive layer 104 is connected to the second boundary line 1041, and the anode conductive layer 104 covers the third boundary line 1022 of the first conductive layer 102. It can be seen that the first conductive layer 102 and the anode conductive layer 104 have both undergone two shrinkages and extended a certain distance toward the fan-out area 20a. In this way, it is not necessary to shrink the first conductive layer 102 directly to the display area 10 along the shortest path. The distance of the water vapor channel that may be formed can be extended, and the intrusion of water vapor can be delayed. Therefore, water vapor can be prevented from entering the display area 10 of the display substrate through the water vapor channel, causing the organic light-emitting layer of the light-emitting device to fail, thereby avoiding the occurrence of continuously expanding dark spots due to the failure of the organic light-emitting layer, thereby improving the display effect of the display substrate.

[0097] In some embodiments, as Figure 4b and 5b As shown, the blocking structure 200 further includes: a second blocking dam 202; the second blocking dam 202 is located on a side of the first blocking dam 201 away from the display area 10; the orthographic projection of the second blocking dam 202 on the substrate 101 at least partially covers the orthographic projections of the third boundary line 1022 and the fourth boundary line 1042 on the substrate 101.

[0098] Specifically, with the above Figure 5a The structure of the display substrate shown is different in that Figure 5bThe barrier structure 200 in the display substrate shown in FIG may include two barrier dams, namely a first barrier dam 201 and a second barrier dam 202. The second barrier dam 202 is further away from the display area 10 than the first barrier dam 201. The third boundary line 1022 of the first conductive layer 102 and the fourth boundary line 1042 of the anode conductive layer 104 are both located below the second barrier dam 202. They extend toward the fan-out region 20a for a distance before shrinking to below the first barrier dam 201. They then extend toward the fan-out region 20a for a distance before shrinking to the display area 10. It can be seen that both the first conductive layer 102 and the anode conductive layer 104 have undergone two shrinkages. This can extend the distance of any water vapor channel that may form, slowing water vapor intrusion. This prevents water vapor from entering the display area 10 of the display substrate through the water vapor channel, potentially causing failure of the organic light-emitting layer of the light-emitting device. This prevents the occurrence of expanding dark spots due to organic light-emitting layer failure, thereby improving the display quality of the display substrate. Furthermore, the integrity of the grooves in the organic material layer can be ensured, preventing the formation of water vapor channels.

[0099] In some embodiments, as Figure 5b and Figure 5c As shown, the first conductive layer 102 also has a first connecting line 1023 connecting the first boundary line 1021 and the third boundary line 1022; the anode conductive layer 104 also has a second connecting line 1043 connecting the second boundary line 1041 and the fourth boundary line 1042; the second connecting line 1043 is located on the side of the first connecting line 1023 close to the fan-out area 20a; the angle between the extension direction of the first connecting line 1023 and the extension direction of the first boundary line 1021 and the third boundary line 1022 is greater than or equal to 90 degrees; the angle between the extension direction of the second connecting line 1043 and the extension direction of the second boundary line 1041 and the fourth boundary line 1042 is greater than or equal to 90 degrees.

[0100] It should be noted that the boundary lines and connection lines in the display substrate provided by the embodiment of the present disclosure are formed by the first conductive layer 102 and the anode conductive layer 104 and other film layers shrinking in the corner area 20b toward the display area. Figure 5cAs shown, the extension direction of the first connection line 1023 is not perpendicular to the extension direction of the first boundary line 1021 and the third boundary line 1022, and the extension direction of the second connection line 1043 is not perpendicular to the extension direction of the second boundary line 1041 and the fourth boundary line 1042, that is, the first connection line 1023 and the second connection line 1043 are both tilted, which can extend the distance between the first connection line 1023 and the second connection line 1043, and further extend the distance of the water vapor channel that may be formed, delaying the intrusion of water vapor, thereby preventing water vapor from entering the interior of the display area 10 of the display substrate through the water vapor channel, causing the organic light-emitting layer of the light-emitting device to fail, thereby avoiding the occurrence of continuously expanding dark spots due to the failure of the organic light-emitting layer, thereby improving the display effect of the display substrate. It can be understood that, as Figure 5b As shown, the extension direction of the first connecting line 1023 can also be perpendicular to the extension direction of the first boundary line 1021 and the third boundary line 1022, and the extension direction of the second connecting line 1043 can also be perpendicular to the extension direction of the second boundary line 1041 and the fourth boundary line 1042. This can reduce the difficulty of preparing the first conductive layer 102 and the anode conductive layer 104, save materials for the first conductive layer 102 and the anode conductive layer 104, and thus save preparation costs.

[0101] In some embodiments, as Figure 5d and Figure 5e The first conductive layer 102 also has a fifth boundary line 1024 that is substantially parallel to the extension direction of the third boundary line 1022; the fifth boundary line 1024 is located on the side of the third boundary line 1022 away from the display area 10; the anode conductive layer 104 also has a sixth boundary line 1044 that is substantially parallel to the extension direction of the fourth boundary line 1042; the sixth boundary line 1044 is located on the side of the fourth boundary line 1042 away from the display area, and the sixth boundary line 1044 is located on the side of the fifth boundary line 1024 away from the display area.

[0102] The fifth boundary line 1024 of the first conductive layer 102 can extend a distance toward the fan-out area 20a and then shrink toward the second blocking dam 202 to form a third boundary line 1022. The third boundary line 1022 shrinks toward the first blocking dam 201 and extends a distance toward the fan-out area 20a to form the first boundary line 1021. Then, the first boundary line 1021 shrinks into the display area 10. Correspondingly, the sixth boundary line 1044 of the anode conductive layer 103 can also extend a distance toward the fan-out area 20a and then shrink toward the second blocking dam 202 to form the fourth boundary line 1042. The fourth boundary line 1042 shrinks toward the first blocking dam 201 and extends a distance toward the fan-out area 20a to form the second boundary line 1041. Then, the second boundary line 1041 shrinks into the display area 10. It can be seen that the first conductive layer 102 and the anode conductive layer 104 have both undergone three shrinkages, and after shrinkage, they extend a certain distance toward the fan-out area 20a. This can extend the distance of the water vapor channel that may be formed and delay the intrusion of water vapor. Therefore, it can prevent water vapor from entering the display area 10 of the display substrate through the water vapor channel, causing the organic light-emitting layer of the light-emitting device to fail, thereby avoiding the occurrence of continuously expanding dark spots due to the failure of the organic light-emitting layer, thereby improving the display effect of the display substrate.

[0103] In some embodiments, as Figure 5d and Figure 5e The display substrate also includes: an interception structure 300 located on the substrate 101 and arranged in the non-display area 20; the interception structure 300 is farther away from the display area 10 than the second blocking dam 202; the orthographic projection of the interception structure 300 on the substrate 101 at least partially covers the orthographic projections of the fifth boundary line 1024 and the sixth boundary line 1044 on the substrate 101.

[0104] The fifth boundary line 1024 of the first conductive layer 102 can be under the interception structure 300 and extend a distance toward the fan-out area 20a, then shrink toward the second blocking dam 202 to form a third boundary line 1022. The third boundary line shrinks toward the first blocking dam 201 and extends a distance toward the fan-out area 20a to form the first boundary line 1021. Then, the first boundary line 1021 shrinks into the display area 10. Correspondingly, the sixth boundary line 1044 of the anode conductive layer 103 can also be under the interception structure 300 and extend a distance toward the fan-out area 20a, then shrink toward the second blocking dam 202 to form a fourth boundary line 1042. The fourth boundary line 1042 shrinks toward the first blocking dam 201 and extends a distance toward the fan-out area 20a to form the second boundary line 1041. Then, the second boundary line 1041 shrinks into the display area 10. It can be seen that the first conductive layer 102 and the anode conductive layer 104 have both undergone three shrinkages, and after shrinkage, they extend a certain distance toward the fan-out area 20a. This can extend the distance of the water vapor channel that may be formed and delay the intrusion of water vapor. Therefore, it can prevent water vapor from entering the display area 10 of the display substrate through the water vapor channel, causing the organic light-emitting layer of the light-emitting device to fail, thereby avoiding the occurrence of continuously expanding dark spots due to the failure of the organic light-emitting layer, thereby improving the display effect of the display substrate.

[0105] In some embodiments, as Figure 5d and Figure 5e As shown, the first conductive layer 102 also has a third connecting line 1025 connecting the third boundary line 1022 and the fifth boundary line 1024; the anode conductive layer 104 also has a fourth connecting line 1045 connecting the fourth boundary line 1042 and the sixth boundary line 1044; the fourth connecting line 1045 is located on the side of the third connecting line 1025 close to the fan-out area 20a; the angle between the extension direction of the third connecting line 1025 and the extension direction of the third boundary line 1022 and the fifth boundary line 1024 is greater than or equal to 90 degrees; the angle between the extension direction of the fourth connecting line 1045 and the extension direction of the fourth boundary line 1042 and the sixth boundary line 1044 is greater than or equal to 90 degrees.

[0106] like Figure 5eAs shown, the extension direction of the third connection line 1025 is not perpendicular to the extension direction of the third boundary line 1022 and the fifth boundary line 1024, and the extension direction of the fourth connection line 1045 is not perpendicular to the extension direction of the fourth boundary line 1042 and the sixth boundary line 1044, that is, the third connection line 1025 and the fourth connection line 1045 are both tilted, which can extend the distance between the third connection line 1025 and the fourth connection line 1045, further extend the distance of the water vapor channel that may be formed, and delay the intrusion of water vapor, thereby preventing water vapor from entering the interior of the display area 10 of the display substrate through the water vapor channel, causing the organic light-emitting layer of the light-emitting device to fail, thereby avoiding the occurrence of continuously expanding dark spots due to the failure of the organic light-emitting layer, thereby improving the display effect of the display substrate. It can be understood that, as Figure 5d As shown, the extension direction of the third connecting line 1025 may also be perpendicular to the extension direction of the third boundary line 1022 and the fifth boundary line 1024, and the extension direction of the fourth connecting line 1045 may also be perpendicular to the extension direction of the fourth boundary line 1042 and the sixth boundary line 1044. This can reduce the difficulty of preparing the first conductive layer 102 and the anode conductive layer 104, save materials for the first conductive layer 102 and the anode conductive layer 104, and thus save preparation costs.

[0107] In some embodiments, as Figure 5f and Figure 5g As shown, the first conductive layer 102 also has a seventh boundary line 1026 that is basically parallel to the extension direction of the third boundary line 1022; the seventh boundary line 1026 is located between the first boundary line 1021 and the third boundary line 1022; the anode conductive layer 104 also has an eighth boundary line 1046 that is basically parallel to the extension direction of the fourth boundary line 1042; the eighth boundary line 1046 is located between the second boundary line 1041 and the fourth boundary line 1042, and the eighth boundary line 1046 is located on the side of the seventh boundary line 1026 away from the display area 10.

[0108] The fifth boundary line 1024 of the first conductive layer 102 shrinks to form a third boundary line 1022. The third boundary line 1022 can extend a distance toward the fan-out area 20a before shrinking to form a seventh boundary line 1026. The seventh boundary line 1026 shrinks and extends a distance toward the fan-out area 20a before forming the first boundary line 1021. The first boundary line 1021 shrinks into the display area 10. Correspondingly, the sixth boundary line 1044 of the anode conductive layer 103 shrinks to form a fourth boundary line 1042. The fourth boundary line 1042 can extend a distance toward the fan-out area 20a before shrinking to form an eighth boundary line 1046. The eighth boundary line 1046 shrinks and extends a distance toward the fan-out area 20a before forming the second boundary line 1041. The second boundary line 1041 shrinks into the display area 10. It can be seen that the first conductive layer 102 and the anode conductive layer 104 have both undergone four shrinkages and extended a distance toward the fan-out area 20a after shrinkage. This can extend the distance of the water vapor channel that may be formed and delay the intrusion of water vapor. Therefore, it can prevent water vapor from entering the display area 10 of the display substrate through the water vapor channel, causing the organic light-emitting layer of the light-emitting device to fail, thereby avoiding the occurrence of continuously expanding dark spots due to the failure of the organic light-emitting layer, thereby improving the display effect of the display substrate.

[0109] In some embodiments, as Figure 5f and Figure 5g As shown, the first blocking dam 201 includes: a first sub-blocking dam 2011 and a second sub-blocking dam 2012; the first sub-blocking dam 2011 is closer to the display area 10 than the second sub-blocking dam 2012; the orthographic projection of the first sub-blocking dam 2011 on the substrate 101 at least partially covers the orthographic projections of the first boundary line 1021 and the second boundary line 1041 on the substrate 101; the orthographic projection of the second sub-blocking dam 2012 on the substrate 101 at least partially covers the orthographic projections of the seventh boundary line 1026 and the eighth boundary line 1046 on the substrate 101.

[0110] The first barrier dam 201 may be composed of a first sub-barrier dam 2011 and a second sub-barrier dam 2022. The first sub-barrier dam 2011 and the second sub-barrier dam 2012 are connected together at one end away from the fan-out region 20a. The seventh boundary line 1026 of the first conductive layer 102 may be below the second sub-barrier dam 2012. The seventh boundary line 1026 may be contracted to form the first boundary line 1021. The first boundary line 1021 may be below the first sub-barrier dam 2011. Correspondingly, the eighth boundary line 1046 of the anode conductive layer 104 may be below the second sub-barrier dam 2012. The eighth boundary line 1046 may be contracted to form the second boundary line 1041. The second boundary line 1041 may be below the first sub-barrier dam 2011. In this way, the first conductive layer 102 and the anode conductive layer 104 have both undergone four shrinkages, and after shrinkage, they extend a certain distance toward the fan-out area 20a. This can extend the distance of the water vapor channel that may be formed and delay the intrusion of water vapor. Therefore, it can prevent water vapor from entering the display area 10 of the display substrate through the water vapor channel, causing the organic light-emitting layer of the light-emitting device to fail, thereby avoiding the occurrence of continuously expanding dark spots due to the failure of the organic light-emitting layer, thereby improving the display effect of the display substrate.

[0111] In some embodiments, as Figure 5f and Figure 5g As shown, the first conductive layer 102 further has a fifth connection line 1027 connecting the first boundary line 1021 and the seventh boundary line 1026, and a sixth connection line 1028 connecting the third boundary line 1022 and the seventh boundary line 1026; the anode conductive layer 104 further has a seventh connection line 1047 connecting the second boundary line 1041 and the eighth boundary line 1046, and an eighth connection line 1048 connecting the fourth boundary line 1042 and the eighth boundary line 1046; the seventh connection line 1047 is located on the side of the fifth connection line 1027 close to the fan-out area 20a, and the eighth connection line 1048 is located on the side of the sixth connection line 1028 close to the fan-out area 20a one side; the angle between the extension direction of the fifth connecting line 1027 and the extension direction of the first boundary line 1021 and the seventh boundary line 1026 is greater than or equal to 90 degrees; the angle between the extension direction of the sixth connecting line 1028 and the extension direction of the third boundary line 1022 and the seventh boundary line 1026 is greater than or equal to 90 degrees; the angle between the extension direction of the seventh connecting line 1047 and the extension direction of the second boundary line 1041 and the eighth boundary line 1046 is greater than or equal to 90 degrees; the angle between the extension direction of the eighth connecting line 1048 and the extension direction of the fourth boundary line 1042 and the eighth boundary line 1046 is greater than or equal to 90 degrees.

[0112] like Figure 5gAs shown, the extension direction of the fifth connecting line 1027 is not perpendicular to the extension direction of the first boundary line 1021 and the seventh boundary line 1026, and the extension direction of the sixth connecting line 1028 is not perpendicular to the extension direction of the third boundary line 1022 and the seventh boundary line 1026, that is, the fifth connecting line 1027 and the sixth connecting line 1028 are both arranged at an angle, which can extend the distance between the fifth connecting line 1027 and the sixth connecting line 1028, and further extend the distance of the water vapor channel that may be formed, delaying the intrusion of water vapor, thereby preventing water vapor from entering the interior of the display area 10 of the display substrate through the water vapor channel, causing the organic light-emitting layer of the light-emitting device to fail, thereby avoiding the occurrence of continuously expanding dark spots due to the failure of the organic light-emitting layer, thereby improving the display effect of the display substrate. Similarly, the seventh connection line 1047 and the eighth connection line 1048 can also be arranged at an angle, so that the distance between the seventh connection line 1047 and the eighth connection line 1048 can be extended, and the distance of the water vapor channel that may be formed can be further extended, delaying the intrusion of water vapor, thereby preventing water vapor from entering the interior of the display area 10 of the display substrate through the water vapor channel and causing the organic light-emitting layer of the light-emitting device to fail, thereby avoiding the occurrence of continuously expanding dark spots due to the failure of the organic light-emitting layer, thereby improving the display effect of the display substrate. It can be understood that if Figure 5f As shown, the fifth connecting line 1027, the sixth connecting line 1028, the seventh connecting line 1047 and the eighth connecting line 1048 can also be arranged perpendicular to their corresponding boundary lines. This can reduce the difficulty of preparing the first conductive layer 102 and the anode conductive layer 104, save materials for the first conductive layer 102 and the anode conductive layer 104, and thus save preparation costs.

[0113] In some embodiments, as Figure 5h and Figure 5i As shown, the first conductive layer 102 also has a ninth boundary line 1029 that is substantially parallel to the extension direction of the third boundary line 1022; the ninth boundary line 1029 is located on the side of the third boundary line 1022 away from the display area 10; the anode conductive layer 104 also has a tenth boundary line 1049 that is substantially parallel to the extension direction of the fourth boundary line 1042; the tenth boundary line 1049 is located on the side of the fourth boundary line 1042 away from the display area 10, and the tenth boundary line 1049 is located on the side of the ninth boundary line 1029 away from the display area 10.

[0114] The fifth boundary line 1024 of the first conductive layer 102 may extend toward the fan-out region 20a for a distance before contracting to form a ninth boundary line 1029. The ninth boundary line 1029 contracts and extends toward the fan-out region 20a for a distance before forming a third boundary line 1022. The third boundary line 1022 contracts to form a first boundary line 1021. The first boundary line 1021 contracts into the display region 10. Correspondingly, the sixth boundary line 1044 of the anode conductive layer 103 may extend toward the fan-out region 20a for a distance before contracting to form a tenth boundary line 1049. The tenth boundary line 1049 contracts and extends toward the fan-out region 20a for a distance before forming a fourth boundary line 1042. The fourth boundary line 1042 contracts to form a second boundary line 1041. The second boundary line 1041 contracts into the display region 10. It can be seen that the first conductive layer 102 and the anode conductive layer 104 have both undergone four shrinkages and extended a distance toward the fan-out area 20a after shrinkage. This can extend the distance of the water vapor channel that may be formed and delay the intrusion of water vapor. Therefore, it can prevent water vapor from entering the display area 10 of the display substrate through the water vapor channel, causing the organic light-emitting layer of the light-emitting device to fail, thereby avoiding the occurrence of continuously expanding dark spots due to the failure of the organic light-emitting layer, thereby improving the display effect of the display substrate.

[0115] In some embodiments, as Figure 5h and Figure 5i As shown, the second blocking dam 202 includes: a third sub-blocking dam 2021 and a fourth sub-blocking dam 2022; the third sub-blocking dam 2021 is closer to the display area 10 than the fourth sub-blocking dam 2022; the orthographic projection of the third sub-blocking dam 2021 on the substrate 101 at least partially covers the orthographic projections of the third boundary line 1022 and the fourth boundary line 1042 on the substrate 101; the orthographic projection of the fourth sub-blocking dam 2022 on the substrate 101 at least partially covers the orthographic projections of the ninth boundary line 1029 and the tenth boundary line 1049 on the substrate 101.

[0116] The second barrier dam 202 may be composed of a third sub-barrier dam 2021 and a fourth sub-barrier dam 2022, which are connected together at one end away from the fan-out region 20a. The ninth boundary line 1029 of the first conductive layer 102 may be below the fourth sub-barrier dam 2022, and the ninth boundary line 1029 may be contracted to form the third boundary line 1022, which may be below the third sub-barrier dam 2021. Correspondingly, the tenth boundary line 1049 of the anode conductive layer 104 may be below the fourth sub-barrier dam 2022, and the tenth boundary line 1049 may be contracted to form the fourth boundary line 1042, which may be below the third sub-barrier dam 2021. In this way, the first conductive layer 102 and the anode conductive layer 104 have both undergone four shrinkages, and after shrinkage, they extend a certain distance toward the fan-out area 20a. This can extend the distance of the water vapor channel that may be formed and delay the intrusion of water vapor. Therefore, it can prevent water vapor from entering the display area 10 of the display substrate through the water vapor channel, causing the organic light-emitting layer of the light-emitting device to fail, thereby avoiding the occurrence of continuously expanding dark spots due to the failure of the organic light-emitting layer, thereby improving the display effect of the display substrate.

[0117] In some embodiments, as Figure 5h and Figure 5i As shown, the first conductive layer 102 further includes a ninth connecting line 1030 connecting the third boundary line 1022 and the ninth boundary line 1029, and a tenth connecting line 1031 connecting the fifth boundary line 1024 and the ninth boundary line 1029; the anode conductive layer 104 further includes an eleventh connecting line 1050 connecting the fourth boundary line 1042 and the tenth boundary line 1049, and a twelfth connecting line 1051 connecting the sixth boundary line 1044 and the tenth boundary line 1049; the eleventh connecting line 1050 is located on the side of the ninth connecting line 1030 close to the fan-out area 20a, and the twelfth connecting line 1051 is located on the side of the tenth connecting line 1031 close to the fan-out area 20 a side of a; the angle between the extension direction of the ninth connecting line 1030 and the extension directions of the third boundary line 1022 and the ninth boundary line 1029 is greater than or equal to 90 degrees; the angle between the extension direction of the tenth connecting line 1031 and the extension directions of the fifth boundary line 1024 and the ninth boundary line 1029 is greater than or equal to 90 degrees; the angle between the extension direction of the eleventh connecting line 1050 and the extension directions of the fourth boundary line 1042 and the tenth boundary line 1049 is greater than or equal to 90 degrees; the angle between the extension direction of the twelfth connecting line 1051 and the extension directions of the sixth boundary line 1044 and the tenth boundary line 1049 is greater than or equal to 90 degrees.

[0118] like Figure 5iAs shown, the extension direction of the ninth connecting line 1030 is not perpendicular to the extension direction of the third boundary line 1022 and the ninth boundary line 1029, and the extension direction of the tenth connecting line 1031 is not perpendicular to the extension direction of the fifth boundary line 1024 and the ninth boundary line 1029, that is, the ninth connecting line 1030 and the tenth connecting line 1031 are both inclined, which can extend the distance between the ninth connecting line 1030 and the tenth connecting line 1031, and further extend the distance of the water vapor channel that may be formed, delaying the intrusion of water vapor, thereby preventing water vapor from entering the interior of the display area 10 of the display substrate through the water vapor channel, causing the organic light-emitting layer of the light-emitting device to fail, thereby avoiding the occurrence of continuously expanding dark spots due to the failure of the organic light-emitting layer, thereby improving the display effect of the display substrate. Similarly, the eleventh connecting line 1050 and the twelfth connecting line 1051 can also be arranged at an angle, which can extend the distance between the eleventh connecting line 1050 and the twelfth connecting line 1051, further extend the distance of the water vapor channel that may be formed, and delay the intrusion of water vapor, thereby preventing water vapor from entering the interior of the display area 10 of the display substrate through the water vapor channel and causing the organic light-emitting layer of the light-emitting device to fail, thereby avoiding the occurrence of continuously expanding dark spots caused by the failure of the organic light-emitting layer, thereby improving the display effect of the display substrate. Figure 5h As shown, the ninth connecting line 1030, the tenth connecting line 1031, the eleventh connecting line 1050, and the twelfth connecting line 1051 can also be arranged perpendicular to their corresponding boundary lines. This can reduce the difficulty of preparing the first conductive layer 102 and the anode conductive layer 104, save materials for the first conductive layer 102 and the anode conductive layer 104, and thus save preparation costs.

[0119] In some embodiments, as Figure 6 As shown, the display substrate further includes: a pixel defining layer 105 located on the anode conductive layer 104; the thickness of the pixel defining layer 105 in the fan-out area 20a is greater than the thickness in the corner area 20b.

[0120] like Figure 6 As shown, the thickness of the pixel defining layer 105 in different areas is different. The pixel defining layer 105 is arranged on the anode conductive layer 104, which can play a role in flattening. At the position where the first conductive layer 102 is cut off and the second conductive layer 103 is continuously arranged, that is, the fan-out area 20a, the pixel defining layer 105 is thicker, which can avoid the generation of step differences here. In this way, the film layers such as the encapsulation layer covering it can be prevented from generating cracks due to the existence of step differences, thereby avoiding encapsulation failure, thereby preventing water vapor from entering the interior of the display substrate through the water vapor channel, causing the organic light-emitting layer of the light-emitting device to oxidize and fail to emit light normally.

[0121] In some embodiments, as Figure 7As shown, the display substrate also includes: a pixel circuit located between the substrate 101 and the anode conductive layer 104 and arranged in the display area 10, and a light-emitting device 40 located in the area defined by the pixel defining layer 105; the pixel circuit includes: a thin film transistor 50; the thin film transistor 50 includes: an active layer 501, a gate insulating layer 502, a gate electrode 503, an interlayer insulating layer 504, a source electrode 505 and a drain electrode 506 arranged in sequence on the substrate 101; the light-emitting device 40 includes: a first electrode 401 and a second electrode 402 arranged opposite to each other, and an organic light-emitting layer 403 located between the first electrode 401 and the second electrode 402; the drain electrode 506 is connected to the first electrode 401 through a switching electrode 507; the anode conductive layer 104 and the first electrode 401 are arranged on the same layer.

[0122] The thin-film transistor 50 includes an active layer 501, a gate insulating layer 502, a gate electrode 503, an interlayer insulating layer 504, and source and drain electrodes (including a source electrode 505 and a drain electrode 506), which are sequentially disposed on the substrate 101. The source electrode 505 and the drain electrode 506 are connected to both ends of the active layer 501 via vias penetrating the interlayer insulating layer 504 and the gate insulating layer 503. The drain electrode 506 of the thin-film transistor 50 is connected to the first electrode 401 of the light-emitting device 40 via a switching electrode 507 to provide an anode voltage signal to the light-emitting device 40. The provision of the switching electrode 507 allows it to form a parallel structure with the drain electrode 506, thereby reducing the resistance of the electrodes in the thin-film transistor 50 and facilitating the transmission of the anode voltage signal.

[0123] The first electrode 401 of the light-emitting device 40 can be an anode, and an anode voltage signal can be input to the light-emitting device to form holes. The anode can be exposed from the accommodating portion of the pixel defining layer 105. The anode can be arranged in the same layer as the above-mentioned anode conductive layer 104, and the same material and the same process are used in the preparation process to reduce the difficulty of the process and save preparation costs. The second electrode 402 of the light-emitting device 40 can be a cathode, and a cathode voltage signal can be input to the light-emitting device to form electrons. The cathode can be covered on the pixel defining layer 105. In actual applications, the cathode can be set on the entire surface to facilitate access to the cathode voltage signal. The organic light-emitting layer 403 of the light-emitting device 40 can be formed in the accommodating portion of the pixel defining layer 104 using an inkjet printing process using an organic light-emitting material, and excitons are formed under the drive of the voltage signals of the anode and cathode to emit light.

[0124] The anode conductive layer 104 can be provided in the same layer as the first electrode 401 , and can be formed using the same material and the same manufacturing process during the preparation process, thereby reducing the process difficulty and saving the preparation cost.

[0125] In some embodiments, the first conductive layer 102 is disposed on the same layer as the source electrode 505 and the drain electrode 506 ; and the second conductive layer 103 is disposed on the same layer as the transfer electrode 507 .

[0126] The source 505 and drain 506 of the thin film transistor 50 can be provided in the same layer as the first conductive layer 102, and can be formed using the same materials and the same manufacturing process during the manufacturing process, thereby reducing manufacturing difficulty and saving manufacturing costs. Correspondingly, the transfer electrode 507 can be provided in the same layer as the second conductive layer 103, and can be formed using the same materials and the same manufacturing process during the manufacturing process, thereby reducing manufacturing difficulty and saving manufacturing costs.

[0127] In some embodiments, the display substrate further includes: a power supply voltage line connected to the second electrode 402; the power supply voltage line includes: a first sub-power supply voltage line and a second sub-power supply voltage line; the first sub-power supply voltage line is disposed in the same layer as the first conductive layer; and the second sub-power supply voltage line is disposed in the same layer as the second conductive layer. Specifically, the power supply voltage line may be a low-level power supply voltage line VSS. The low-level power supply voltage line VSS may be fabricated using a double-layer structure of the first sub-power supply voltage line and the second sub-power supply voltage line to reduce resistance of the low-level power supply voltage line VSS and ensure transmission of the low-level power supply voltage signal. The first sub-power supply voltage line may be disposed in the same layer as the first conductive layer 102, and the second sub-power supply voltage line may be disposed in the same layer as the second conductive layer 103. During the fabrication process, the same materials and the same fabrication process may be used to reduce process complexity and save fabrication costs.

[0128] In some embodiments, as Figure 7 and Figure 8 As shown, the display substrate also includes: an encapsulation layer 106 located on the pixel defining layer 105; the encapsulation layer 106 may include: a first inorganic encapsulation layer 1061, an organic encapsulation layer 1063 and a second inorganic encapsulation layer 1062 arranged in sequence along a direction away from the substrate 101; the first inorganic encapsulation layer 1061 and the second inorganic encapsulation layer 1062 cover the blocking structure 200 and are terminated on the side of the blocking structure 200 away from the display area 10; the organic encapsulation layer 1062 is terminated on the side of the blocking structure 200 close to the display area 10.

[0129] The encapsulation layer 106 can encapsulate structures such as the second electrode 402 of the light-emitting device 40 to prevent moisture from entering the organic light-emitting layer 403 of the light-emitting device, thereby preventing oxidation of the organic light-emitting layer 403 and causing poor display. Specifically, the encapsulation layer 106 can include: a first inorganic encapsulation layer 1061, an organic encapsulation layer 1063, and a second inorganic encapsulation layer 1062, arranged in sequence along a direction away from the substrate 101. The first and second inorganic encapsulation layers can be formed using inorganic materials such as silicon nitride, silicon oxide, and silicon oxynitride, while the organic encapsulation layer can be formed using organic materials such as epoxy resin. Furthermore, the first and second inorganic encapsulation layers 1061 and 1062 in the encapsulation layer 106 can cover the blocking structure 200 and terminate on the side of the blocking structure 200 away from the display area 10. When an intercepting structure is provided on the side of the blocking structure 200 away from the display area 10, the first and second inorganic encapsulation layers 1061 and 1062 terminate at the intercepting structure. The organic encapsulation layer 1062 is terminated at the side of the blocking structure 200 close to the display area 10 , thereby preventing water vapor from being conducted from the non-display area 20 to the display area 10 through the organic encapsulation layer 1063 .

[0130] In some embodiments, the display substrate further includes: a first organic insulating layer (not shown in the figure) and a second organic insulating layer (not shown in the figure); the first organic insulating layer is located between the first conductive layer and the second conductive layer; the second organic insulating layer is located between the second conductive layer and the anode conductive layer.

[0131] The first organic insulating layer can insulate the first conductive layer 102 and the second conductive layer 103 to prevent short circuits between the two layers in corresponding areas, which could affect signal transmission. It can also cover the first conductive layer 102 to prevent moisture from corroding the first conductive layer 102. Similarly, the second organic insulating layer can insulate the second conductive layer 103 and the anode conductive layer 104 to prevent short circuits between the two layers in corresponding areas, which could affect signal transmission. It can also cover the second conductive layer 103 to prevent moisture from corroding the second conductive layer 103.

[0132] In some embodiments, the first organic insulating layer and the second organic insulating layer are both provided with grooves in corresponding regions between the intercepting structure and the blocking structure.

[0133] The grooves can disconnect the first organic insulating layer and the second organic insulating layer at corresponding positions, thereby preventing a water vapor channel from being formed between the interception structure 300 and the interception structure 200. Therefore, water vapor can be prevented from entering the display area 10 of the display substrate through the water vapor channel, thereby causing the organic light-emitting layer of the light-emitting device to fail, thereby avoiding the occurrence of continuously expanding dark spots due to the failure of the organic light-emitting layer, thereby improving the display effect of the display substrate.

[0134] In some embodiments, as Figure 5j As shown, the second conductive layer 103 has an eleventh boundary line 1032 ; in the corner region 20 b , the eleventh boundary line 1032 is located on a side of the sixth boundary line 1044 away from the display region 10 .

[0135] It is understandable that in Figure 5a-Figure 5i In order to more clearly show the positional relationship between the boundary line and the connection line between the first conductive layer 102 and the anode conductive layer 104, the structure of the second conductive layer 103 is not shown. Figure 5j The structure of the second conductive layer 103 is shown in FIG. Figure 5j As shown, in the corner area 20b, the eleventh boundary line 1032 of the second conductive layer 103 is located on the side of the sixth boundary line 1044 away from the display area 10, so that the second conductive layer 103 can cover the sixth boundary line of the anode conductive layer 104 and the fifth boundary line 1024 of the first conductive layer 102, and damage to the first conductive layer 102 can be avoided when etching the second conductive layer 103.

[0136] In some embodiments, as Figure 5a-5j As shown, the first conductive layer 102 also has a twelfth boundary line 1033 intersecting with the extension direction of the first boundary line 1021; the anode conductive layer 104 also has a thirteenth boundary line 1052 intersecting with the extension direction of the second boundary line 1041; the twelfth boundary line 1033 is located in the fan-out area 20a, and the thirteenth boundary line 1052 is located in the corner area 20b.

[0137] The twelfth boundary line 1033 of the first conductive layer 102 can extend from the fan-out area 20a to the display area 10, and the thirteenth boundary line 1052 of the anode conductive layer 104 can extend from the corner area 20b to the display area 10 to provide a low-level power signal to the light-emitting device 40 in the display area 10.

[0138] In some embodiments, as Figure 8 As shown, in the corner region 20b, at least portions of the first conductive layer 102, the second conductive layer 103, and the anode conductive layer 104 are electrically connected.

[0139] In the corner area 20b, the first conductive layer 102 and the second conductive layer 103 are electrically connected to form a double-layer structure of a low-level power supply voltage line VSS, which is connected to the anode conductive layer 104. The anode conductive layer 104 extends from the corner area 20b to the display area 10 and is connected to the cathode of the light-emitting device 40 in the display area 10 to provide a low-level power supply signal to the light-emitting device in the display area 10, so that the light-emitting device 40 emits light to realize the display function.
