Based on the embodiments provided by the present disclosure, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present disclosure.
[0074] Unless the context requires otherwise, throughout the specification and claims, the term "comprise" and its other forms, such as the third person singular form "comprises" and the present participle form "comprising", are to be interpreted as open and inclusive, that is, "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "example", "specific example" or "some examples" are intended to indicate that the particular features, structures, materials or characteristics associated with the embodiment or example are included in at least one embodiment or example of the present disclosure. The schematic representation of the above terms does not necessarily refer to the same embodiment or example. In addition, the particular features, structures, materials or characteristics may be included in any one or more embodiments or examples in any appropriate manner.
[0075] Terms such as "first" and "second" are used herein to describe various elements, but these elements should not be limited by these terms. These terms are only used to distinguish one component from other components. For example, an element referred to as a first element in one embodiment can be referred to as a second element in another embodiment without departing from the scope of the appended claims. Unless otherwise mentioned, terms in the singular may include plural forms.
[0076] When describing some embodiments, the word "connected" and its derivatives may be used. The term "connected" should be understood in a broad sense. For example, "connected" can mean fixed connection, detachable connection, or integration; it can be directly connected or indirectly connected through an intermediate medium.
[0077] “At least one of A, B and C” has the same meaning as “at least one of A, B or C” and both include the following combinations of A, B and C: A only, B only, C only, the combination of A and B, the combination of A and C, the combination of B and C, and the combination of A, B and C.
[0078] “A and / or B” includes the following three combinations: A only, B only, and a combination of A and B.
[0079] The use of "adapted to" or "configured to" herein is intended to be open and inclusive language that does not exclude devices adapted or configured to perform additional tasks or steps.
[0080] Additionally, the use of “based on” is meant to be open and inclusive, as a process, step, calculation, or other action “based on” one or more stated conditions or values may, in practice, be based on additional conditions or values beyond those stated.
[0081] As used herein, "about," "approximately," or "approximately" are inclusive of the stated value and mean within an acceptable range of deviation for the particular value as determined by one of ordinary skill in the art, taking into account the measurements in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system). For example, "about" can mean within one or more standard deviations, or within ±30%, ±20%, ±10%, ±5% of the stated value.
[0082] As used herein, "parallel", "perpendicular", and "equal" include the situations described and situations similar to the situations described, and the range of the similar situations is within an acceptable deviation range, wherein the acceptable deviation range is as determined by a person of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of the specific quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, wherein the acceptable deviation range of approximate parallelism can be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, wherein the acceptable deviation range of approximate perpendicularity can also be, for example, a deviation within 5°. "Equal" includes absolute equality and approximate equality, wherein the acceptable deviation range of approximate equality can be, for example, that the difference between the two equals is less than or equal to 5% of either one.
[0083] As used herein, "substantially flush" and "substantially overlap" include the conditions described and conditions similar to the conditions described, the range of which is within an acceptable deviation range, wherein the acceptable deviation range is determined by a person of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "substantially flush" includes absolute flushness and approximate flushness, wherein the acceptable deviation range for approximate flushness may be, for example, a deviation within 0.05 mm. For example, "substantially overlap" includes absolute overlap and approximate overlap, wherein the acceptable deviation range for approximate overlap may be, for example, a deviation within 0.05 mm.
[0084] It will be understood that when a layer or element is referred to as being on another layer or substrate, it can be directly on the other layer or substrate, or intervening layers may be present therebetween.
[0085] In addition, the transistors used in the embodiments of the present disclosure may be thin film transistors (TFT), field effect transistors (MOS) or other switching devices with the same characteristics. The embodiments of the present disclosure are described using thin film transistors as an example.
[0086] Exemplary embodiments are described herein with reference to cross-sectional and / or plan views that are idealized exemplary drawings. In the drawings, the thickness of layers and the area of regions are exaggerated for clarity. Therefore, variations in shape relative to the drawings due to, for example, manufacturing techniques and / or tolerances are contemplated. Therefore, the exemplary embodiments should not be construed as limited to the shapes of the regions shown herein, but rather include deviations in shape due to, for example, manufacturing. For example, an etched region shown as a rectangle will typically have curved features. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to illustrate the actual shape of regions of the device and are not intended to limit the scope of the exemplary embodiments.
[0087] In this specification, unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present invention belongs. It will be further understood that, unless expressly defined herein, terms (such as those defined in commonly used dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and should not be interpreted as an ideal or overly formal meaning.
[0088] In this disclosure, terms such as "lower," "below," "above," and "upper," and similar terms are used to explain the relationships between components shown in the drawings. These terms may be relative and described based on directions shown in the drawings, or based on the order in which process steps are formed, but are not limited thereto.
[0089] The term "opposite" means that the first element may be directly or indirectly opposite to the second element. In the case where a third element is interposed between the first and second elements, the first and second elements may be understood to be indirectly opposite to each other although they are still opposite to each other.

[0102] In some embodiments, as shown in FIG. 4 , FIG. 6A and FIG. 6B , the array substrate 10 has a display area A and a peripheral area B located on at least one side of the display area A.
[0103] The display area A is an area for displaying images, and is configured to be provided with a plurality of sub-pixels P and a plurality of signal lines, etc. The peripheral area B is an area for not displaying images, and is configured to be provided with a driving circuit and connection lines, etc.
[0104] For example, as shown in Figures 4 and 8, the peripheral area B includes a first border area B1, the display area A and the first border area B1 are arranged along a first direction X, and the first border area B1 includes a chip setting area C and a binding area D. The chip setting area C is configured to set the driver chip 500 (see Figure 3), and the binding area D is configured to connect to the flexible circuit board 400 (see Figure 3).
[0105] It should be noted that the first direction X can be, for example, the direction of a line connecting the center of the display area A and the center of the first border area B1. The chip setting area C and the binding area D are substantially polygonal in shape. Exemplarily, the chip setting area C and the binding area D are substantially rectangular, pentagonal, hexagonal, or irregular polygonal in shape.
[0106] In this document, "substantially polygonal" means that the chip placement area C and the bonding area D are generally polygonal in shape, but are not limited to standard polygons. Specifically, "polygonal" here encompasses not only basic polygonal shapes but also, taking into account process conditions, shapes similar to polygons. For example, the two sides of a polygon are curved at each intersection (i.e., at a corner), i.e., the corners are smooth, resulting in the chip placement area C and the bonding area D being rounded polygonal in shape.
[0107] Some embodiments of the present disclosure are schematically described below by taking the chip setting area C and the binding area D as being approximately rectangular as an example, but the embodiments of the present disclosure are not limited thereto.
[0108] It should be understood that the chip placement area C needs to be provided with the driver chip 500, and the bonding area D only needs to be connected to the flexible circuit board 400. Therefore, in the first direction X, the width of the chip placement area C can be greater than the width of the bonding area D.
[0109] 8 , the width of the binding area D is 0.35 mm to 1 mm in the first direction X. For example, the width of the binding area D is any one of 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm, 0.7 mm, 0.75 mm, 0.8 mm, 0.85 mm, 0.9 mm, 0.95 mm, and 1 mm in the first direction X.
[0110] 8 , the width of the chip placement area C in the first direction X is 0.6 mm to 1.2 mm. For example, the width of the chip placement area C in the first direction X is any one of 0.6 mm, 0.65 mm, 0.7 mm, 0.75 mm, 0.8 mm, 0.85 mm, 0.9 mm, 0.95 mm, 1 mm, 1.05 mm, 1.1 mm, 1.15 mm, and 1.2 mm.
[0111] Furthermore, the aforementioned binding area D is located away from the boundary of the display area A and can be substantially flush with the boundary of the chip placement area C away from the display area A. In this way, the distance between the binding area D and the display area A can be increased without increasing the width of the first border area B1 in the first direction X, thereby facilitating the arrangement of traces (e.g., the peripheral connection lines 130 in FIG. 12A ) or other circuit structures (e.g., the first test pads 1641 in FIG. 18 ) between the binding area D and the display area A.
[0112] In some embodiments, referring to Figures 4 and 5 , the boundary of the first border region B1 of the array substrate 10 extends beyond the boundary of the color filter substrate 20. The boundary of the array substrate 10 away from the first border region B1 and the two boundaries in the second direction Y are substantially flush with the boundary of the color filter substrate 20. It should be noted that the second direction Y intersects with the first direction X; for example, the second direction Y is substantially perpendicular to the first direction X.
[0113] For example, as shown in Figures 4 and 5, the peripheral area B may further include a second border area B2, a third border area B3, and a fourth border area B4. The second border area B2 is located on a side of the display area A away from the first border area B1. Along the second direction Y, the third border area B3 and the fourth border area B4 are located on opposite sides of the display area A.
[0114] The boundaries of the second frame area B2 , the third frame area B3 and the fourth frame area B4 of the array substrate 10 are substantially flush with the boundaries of the color filter substrate 20 .
[0115] In addition, referring to Figures 8 to 11, the chip setting area C and the binding area D of the array substrate 10 can be located between the boundary of the first border area B1 of the array substrate 10 and the boundary of the color filter substrate 20, so as to facilitate the connection of the flexible circuit board 400 (see Figure 3) and the driving chip 500 (see Figure 3) with the array substrate 10.
[0116] Exemplarily, the distance between the boundary of the first border area B1 of the color film substrate 20 and the boundary of the display area A is 0.9 mm to 2.5 mm. For example, the distance between the boundary of the first border area B1 of the color film substrate 20 and the boundary of the display area A is any one of 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, and 2.5 mm.
[0117] Exemplarily, the distance between the boundary of the first border area B1 of the color filter substrate 20 and the boundary of the chip placement area C is 0.29 mm to 1.5 mm. For example, the distance between the boundary of the first border area B1 of the color filter substrate 20 and the boundary of the chip placement area C is any one of 0.29 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, and 1.5 mm.
[0118] Exemplarily, the distance between the boundary of the first border area B1 and the boundary of the binding area D of the color film substrate 20 is 0.49 mm to 2.35 mm. For example, the distance between the boundary of the first border area B1 and the boundary of the binding area D of the color film substrate 20 is any one of 0.49 mm, 0.5 mm, 0.55 mm, 0.6 mm, 0.7 mm, 0.75 mm, 0.8 mm, 0.9 mm, 1 mm, 1.2 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.65 mm, 1.7 mm, 1.9 mm, 2 mm, 2.1 mm, 2.2 mm, 2.3 mm, and 2.35 mm.
[0119] Some embodiments of the present disclosure are schematically described below by taking the peripheral area B including the first border area B1, the second border area B2, the third border area B3 and the fourth border area B4 as an example, but the implementation methods of the present disclosure are not limited thereto.
[0120] 6A and 6B , the array substrate 10 includes a first substrate 11 and a plurality of driving pads 110 , a plurality of binding pins 120 , and a plurality of peripheral connection lines 130 disposed on the first substrate 11 .
[0121] 4 , 6A and 8 , all driving pads 110 are disposed in the chip arrangement area C and are configured to connect to the driving chip 500 . That is, the driving chip 500 is provided with pins, and the driving chip 500 is connected to the driving pads 110 via the pins.
[0122] 4 , 6A and 8 , all the binding pins 120 are disposed in the binding area D and are configured to connect to the flexible circuit board 400. That is, the flexible circuit board 400 is provided with gold fingers, and the flexible circuit board 400 is connected to the binding pins 120 via the gold fingers.
[0123] As shown in FIG. 4 , FIG. 6A and FIG. 12A , all peripheral connection lines 130 are disposed in the first border area B1 and are located between the boundary of the first border area B1 of the array substrate 10 and the boundary of the color filter substrate 20 .
[0124] One end of each peripheral connection line 130 is connected to the driving pad 110 , and the other end is connected to the binding pin 120 , so as to connect the flexible circuit board 400 to the driving chip 500 , thereby providing various required signals to the driving chip 500 and the display panel 100 .
[0125] In the related art, the binding pins are located on the side of the driving pads away from the display area, that is, the binding area is located below the chip installation area. This arrangement requires a large width design of the first border area in the first direction, which is not conducive to the narrow border design of the display device.
[0126] Based on this, referring to FIG. 7 to FIG. 11 , some embodiments of the present disclosure provide an array substrate 10 , in which the binding area D is located on at least one side of the chip placement area C along the second direction Y.
[0127] That is to say, in the first border area B1, the binding pins 120 are arranged in the areas on both sides of all the driving pads 110 along the second direction Y. This can avoid increasing the width of the first border area B1 in the first direction X, thereby reducing the lower border of the display device 1000 (see Figure 1) and increasing the screen-to-body ratio.
[0128] Exemplarily, as shown in FIG. 7 to FIG. 11 , along the second direction Y, the binding area D is located on two opposite sides of the chip setting area C, that is, the plurality of binding pins 120 are respectively disposed on two opposite sides of all the driving pads 110 .
[0129] For example, as shown in Figures 7 to 11 , the bonding area D includes a first bonding area D1 and a second bonding area D2. Along the second direction Y, the first bonding area D1 and the second bonding area D2 are located on opposite sides of the chip placement area C. In other words, the plurality of bonding pins 120 can be disposed in the first bonding area D1 and the second bonding area D2, respectively. Furthermore, the plurality of bonding pins 120 can be symmetrically disposed on opposite sides of all driving pads 110.
[0130] On this basis, as shown in Figures 7 to 14, the array substrate 10 has an axis Z extending along the first direction X, and multiple driving pads 110, multiple binding pins 120 and multiple peripheral connection lines 130 can be arranged symmetrically about the axis Z to simplify the circuit structure, improve the regularity of the circuit routing, and reduce the preparation cost. Of course, multiple driving pads 110, multiple binding pins 120 and multiple peripheral connection lines 130 can also be arranged symmetrically about the axis Z. For example, the number of driving pads 110, binding pins 120 and peripheral connection lines 130 located on one side of the axis Z is greater than the number of driving pads 110, binding pins 120 and peripheral connection lines 130 located on the other side of the axis Z.
[0131] Referring to Figures 4, 5, and 8, the display device 1000 includes two flexible circuit boards 400, which are respectively connected to the binding pins 120 of the first binding area D1 and the binding pins 120 of the second binding area D2. This arrangement not only avoids increasing the width of the first border area B1 in the first direction X, thereby reducing the bottom border of the display device 1000, but also facilitates the routing of the peripheral connection lines 130, thereby reducing the routing width occupied by all peripheral connection lines 130 in the first direction X.
[0132] 5 and 8 , the array substrate 10 may further include alignment marks 40 . The alignment marks 40 are disposed on opposite sides of the binding region D along the second direction Y to facilitate alignment and connection between the flexible circuit board 400 and the binding pins 120 of the binding region D.
[0133] It should be noted that the shape of the orthographic projection of the alignment mark 40 on the substrate 11 can be a cross, a T-shape, a quadrilateral, a circle, etc., which is not specifically limited in the embodiment of the present disclosure.
[0134] In some embodiments, referring to FIG. 6B , FIG. 8 , and FIG. 12A , the plurality of peripheral connection lines 130 include a first peripheral connection line 131 . The first peripheral connection line 131 extends within the chip arrangement region C to a side of the chip arrangement region C adjacent to the bonding region D. Furthermore, one end of the first peripheral connection line 131 is connected to the driving pad 110 within the chip arrangement region C, and the other end is connected to the bonding pin 120 of the bonding region D.
[0135] It should be noted that when the first border area B1 includes two binding areas D, one end of the first peripheral connection line 131 is connected to the driving pad 110, and the other end extends to the side of the chip setting area C close to the closer of the two binding areas D, and is connected to the binding pin 120 of the closer binding area D.
[0136] 6B and 15A , the first peripheral connection line 131 includes a first routing segment 1311 , a second routing segment 1312 and a first connecting segment 1313 connected in sequence, the first routing segment 1311 is connected to the driving pad 110 , and the first connecting segment 1313 is connected to the binding pin 120 .
[0137] 6B , 8 , and 15A , the first trace segment 1311 is disposed in the chip placement area C and extends substantially along the first direction X. The second trace segment 1312 is disposed in the chip placement area C and extends substantially along the second direction Y to a side of the chip placement area C near the bonding area D.
[0138] In this case, in the first direction X, the first peripheral connection line 131 can be routed inside the chip setting area C where it overlaps with the chip setting area C, avoiding routing outside the chip setting area C, which would increase the width of the first border area B1 in the first direction X.
[0139] It should be understood that, as shown in FIG. 8 to FIG. 11 , the plurality of driving pads 110 are arranged into a plurality of driving pad groups 1100 , and the plurality of driving pad groups 1100 include an output pad group 1110 and an input pad group 1120 .
[0140] As shown in Figures 8 to 14 , the output pad group 1110 includes a plurality of output pads 1111 arranged along the second direction Y. The input pad group 1120 includes a plurality of input pads 1121 arranged along the second direction Y. One end of the first peripheral connection line 131 is connected to the input pad 1121 , and the other end is connected to the binding pin 120 .
[0141] On this basis, along the second direction Y, the input pad group 1120 is located on at least one side of the output pad group 1110. Alternatively, the input pad group 1120 is located on a side of the output pad group 1110 away from the display area A.
[0142] In some embodiments, as shown in FIG. 10 and FIG. 11 , along the second direction Y, the input pad group 1120 is located on at least one side of the output pad group 1110 .
[0143] 10 and 11 , the bonding region D includes a first bonding region D1 and a second bonding region D2. Along the second direction Y, the first bonding region D1 and the second bonding region D2 are respectively located on opposite sides of the chip setting region C. In this case, the plurality of input pads 1121 may be symmetrically arranged on opposite sides of the output pad group 1110.
[0144] For example, as shown in FIG. 10 , the plurality of driving pad groups 1100 are close to the boundary of the display area A and substantially coincide with the boundary of the chip placement area C close to the display area A.
[0145] On this basis, referring to Figures 10 and 13 , all peripheral connection lines 130 may be first peripheral connection lines 131. The first peripheral connection lines 131 extend from the side of the plurality of driving pad groups 1100 away from the display area A to the side of the chip arrangement area C near the bonding area D. Furthermore, one end of the first peripheral connection line 131 is connected to the end of the input pad group 1120 away from the display area A, and the other end is connected to the end of the bonding pin 120 near the display area A.
[0146] In this way, there is no circuit wiring on the side of the chip setting area C and the binding area D away from the display area A. That is, the distance between the chip setting area C and the binding area D and the boundary of the first frame area B1 away from the display area A can be designed to be extremely small.
[0147] For example, the distance between the chip placement area C and the boundary of the first border area B1 away from the display area A is 0.07 mm to 0.2 mm. For example, the distance between the chip placement area C and the boundary of the first border area B1 away from the display area A is any one of 0.07 mm, 0.08 mm, 0.09 mm, 0.1 mm, 0.12 mm, 0.15 mm, 0.18 mm, and 0.2 mm.
[0148] For example, the distance between the binding area D and the boundary of the first border area B1 away from the display area A is 0.07 mm to 0.2 mm. For example, the distance between the binding area D and the boundary of the first border area B1 away from the display area A is any one of 0.07 mm, 0.08 mm, 0.09 mm, 0.1 mm, 0.12 mm, 0.15 mm, 0.18 mm, and 0.2 mm.
[0149] For another example, as shown in FIG. 11 , the plurality of driving pad groups 1100 are close to the boundary of the display area A and substantially coincide with the boundary of the chip arrangement area C away from the display area A.
[0150] On this basis, referring to Figures 11 and 14 , all peripheral connection lines 130 may be first peripheral connection lines 131. The first peripheral connection lines 131 extend from the side of the plurality of driving pad groups 1100 close to the display area A to the side of the chip setting area C close to the bonding area D. Furthermore, one end of the first peripheral connection line 131 is connected to the end of the input pad group 1120 close to the display area A, and the other end is connected to the end of the bonding pin 120 close to the display area A.
[0151] In this way, there is no circuit wiring on the side of the chip setting area C and the binding area D away from the display area A. That is, the distance between the chip setting area C and the binding area D and the boundary of the first frame area B1 away from the display area A can be designed to be extremely small.
[0152] For example, the distance between the chip placement area C and the boundary of the first border area B1 away from the display area A is 0.07 mm to 0.2 mm. For example, the distance between the chip placement area C and the boundary of the first border area B1 away from the display area A is any one of 0.07 mm, 0.08 mm, 0.09 mm, 0.1 mm, 0.12 mm, 0.15 mm, 0.18 mm, and 0.2 mm.
[0153] For example, the distance between the binding area D and the boundary of the first border area B1 away from the display area A is 0.07 mm to 0.2 mm. For example, the distance between the binding area D and the boundary of the first border area B1 away from the display area A is any one of 0.07 mm, 0.08 mm, 0.09 mm, 0.1 mm, 0.12 mm, 0.15 mm, 0.18 mm, and 0.2 mm.
[0154] In other embodiments, as shown in FIG. 8 and FIG. 9 , the input pad group 1120 is located on a side of the output pad group 1110 away from the display area A.
[0155] On this basis, referring to Figures 8, 9, and 12A, first peripheral connection line 131 extends between input pad group 1120 and output pad group 1110 to a side of chip arrangement area C near bonding area D. Furthermore, one end of first peripheral connection line 131 is connected to one end of input pad 1121 near output pad group 1110, and the other end is connected to one end of bonding pin 120 near display area A.
[0156] Here, the distance between the first peripheral connection line 131 and the output pad group 1110 is greater than or equal to 20 μm to avoid the risk of crushing the first peripheral connection line 131 during the bonding process of the driver chip 500 .
[0157] Some embodiments of the present disclosure are schematically described below by taking the example where the input pad group 1120 is located on a side of the output pad group 1110 away from the display area A, but the embodiments of the present disclosure are not limited thereto.
[0158] It can be understood that, referring to Figures 6B, 8, 12A and 15A, in the chip setting area C, it is not possible to make all the peripheral connection lines 130 within the chip setting area C. In the case where the plurality of peripheral connection lines 130 extend to the side of the chip setting area C close to the binding area D, the plurality of peripheral connection lines 130 also include a second peripheral connection line 132.
[0159] The second peripheral connection line 132 extends from the side of the chip arrangement area C away from the display area A to the side of the chip arrangement area C close to the bonding area D. Furthermore, one end of the second peripheral connection line 132 is connected to the end of the input pad 1121 away from the output pad group 1110, and the other end is connected to the end of the bonding pin 120 in the bonding area D close to the display area A.
[0160] In some embodiments, referring to FIG. 15B and FIG. 15C , input pad group 1120 includes multiple input pad subgroups 1122 . Input pad subgroup 1122 includes multiple input pads 1121 that are adjacently disposed and transmit the same signal.
[0161] At this time, as shown in Figures 12B, 15B, and 15C, the plurality of second peripheral connection lines 132 include first-type second peripheral connection lines 321 and second-type second peripheral connection lines 322. The first-type second peripheral connection lines 321 are connected to the binding pins 120 and one input solder subgroup 1122. The second-type second peripheral connection lines 322 are connected to the binding pins 120 and at least two input solder subgroups 1122, and the second-type second peripheral connection lines 322 are located on a side of the first-type second peripheral connection lines 321 away from the display area A.
[0162] Exemplarily, as shown in FIG. 12B , along the second direction Y, the binding areas D are located on two opposite sides of the chip setting area C, that is, the first border area B1 includes two binding areas D.
[0163] At this time, as shown in Figures 12B and 15B, the plurality of second peripheral connection lines 132 may include, for example, two first-type second peripheral connection lines 321 and one second-type second peripheral connection line 322. The two first-type second peripheral connection lines 321 are respectively connected to the input solder subgroup 1122 and the binding pins 120 on the first side of the chip setting area C (e.g., the left side in Figure 12B). The two first-type second peripheral connection lines 321 are sequentially away from the display area A. The one second-type second peripheral connection line 322 is connected to the binding pins 120 on the first side of the chip setting area C (e.g., the left side in Figure 12B) and the two input solder subgroups 1122. The second-type second peripheral connection line 322 is located on the side of the two first-type second peripheral connection lines 321 away from the display area A.
[0164] In some embodiments, as shown in Figures 12B and 15C, the array substrate 10 further includes an input transfer line 323, which is disposed in the chip placement area C and connected to at least two input solder subgroups 1122. Among the at least two input solder subgroups 1122, one input solder subgroup 1122 is also connected to a second peripheral connection line 132.
[0165] Exemplarily, as shown in FIG. 12B , along the second direction Y, the binding areas D are located on two opposite sides of the chip setting area C, that is, the first border area B1 includes two binding areas D.
[0166] At this time, as shown in FIG12B and FIG15C , the plurality of second peripheral connection lines 132 include two first-type second peripheral connection lines 321. The two first-type second peripheral connection lines 321 are respectively connected to the input pad plate group 1122 and the bonding pins 120 on the second side (e.g., the right side in FIG12B ) of the chip setting area C. The two first-type second peripheral connection lines 321 are sequentially away from the display area A.
[0167] On this basis, as shown in Figures 12B and 15C, the array substrate 10 further includes an input adapter line 323, which is connected to three input solder sub-groups 1122. Of the three input solder sub-groups 1122, two input solder sub-groups 1122 and one input solder sub-group 1122 are located on opposite sides of the input solder sub-group 1122 connected to the first-type second peripheral connection line 321, which is relatively far from the display area A. Furthermore, the one input solder sub-group 1122 is connected to the first-type second peripheral connection line 321, which is relatively close to the display area A.
[0168] The second peripheral connection line 132 can transmit a signal with a high resistance requirement, so that the width of the second peripheral connection line 132 can be increased to reduce the resistance. For example, a second peripheral connection line 132 transmits a common voltage signal.
[0169] It should be noted that when the first border area B1 includes two binding areas D, one end of the second peripheral connection line 132 is connected to the driving pad 110, and the other end extends to the side of the chip setting area C close to the closer of the two binding areas D, and is connected to the binding pin 120 of the closer binding area D.
[0170] For example, as shown in Figures 6B, 8, and 15A, the second peripheral connection line 132 includes a third routing segment 1321, a fourth routing segment 1322, and a second connecting segment 1323, which are connected in sequence. The third routing segment 1321 is connected to the driving pad 110, and the second connecting segment 1323 is connected to the binding pin 120. The first routing segment 1311 is disposed in the chip arrangement area C and extends substantially along the first direction X. The second routing segment 1312 is disposed in the chip arrangement area C and extends substantially along the second direction Y to a side of the chip arrangement area C near the binding area D.
[0171] In this case, among all the peripheral connection lines 130, a portion of the peripheral connection lines 130 (i.e., the first peripheral connection lines 131) are within the chip setting area C and extend to the side of the chip setting area C close to the binding area D, so as to reduce the first border area B1; another portion of the peripheral connection lines 130 (i.e., the second peripheral connection lines 132) are on the side of the chip setting area C away from the display area A and extend to the side of the chip setting area C close to the binding area D, so as to avoid interference with other circuits or driving pads 110 within the chip setting area C.
[0172] 8 and 9 , the distance between the chip placement area C and the first boundary is a first distance L1, and the distance between the binding area D and the first boundary is a second distance L2. The first boundary is the boundary of the first frame area B1 of the array substrate 10 away from the display area A.
[0173] As shown in Figures 8 and 9, the first distance L1 may be greater than the second distance L2. For example, the difference between the first distance L1 and the second distance L2 is 0.3 mm to 0.6 mm. For example, the difference between the first distance L1 and the second distance L2 is any one of 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.55 mm, and 0.6 mm.
[0174] In some embodiments, as shown in FIG12A and FIG15A , the binding pin 120 connected to the first peripheral connection line 131 is a first binding pin 121 , and the binding pin 120 connected to the second peripheral connection line 132 is a second binding pin 122 .
[0175] The first binding pins 121 are located further away from the chip placement area C than the second binding pins 122, and the second peripheral connection lines 132 are located on the side of the first peripheral connection lines 131 that is further away from the display area A. This arrangement allows the first and second peripheral connection lines 131, 132 to be staggered, simplifying circuit routing. Furthermore, the first and second peripheral connection lines 131, 132 are provided on the same layer and made of the same material, reducing manufacturing costs.
[0176] It should be understood that during the manufacturing process of the display device, after the circuits and signal lines in the array substrate 10 are completed, it is necessary to use a test circuit to detect the circuits and signal lines in the array substrate 10 to determine whether there is a short circuit or open circuit problem in the array substrate 10.

Furthermore, with reference to Figure 8, the output pad group 1110 includes data output pads 1112, and the data lines 140 are further connected to the data output pads 1112 to receive data signals output by the driver chip 500 (see Figure 3) or data signals output by an external circuit.

The test circuit 160 is configured to receive test signals transmitted from an external circuit during a test phase to test the circuits and signal lines in the array substrate 10 .

[0192] It should be noted that the “idle area” refers to an area where no circuit structure (eg, driving pads 110 ) or circuit traces (eg, peripheral connection lines 130 ) are set.
[0193] When the idle area in the chip setting area C is small and the first test circuit 161 cannot be set in the chip setting area C, as shown in FIG. 6B , the first test circuit 161 can be set in the second border area B2 and connected to the plurality of data lines 140 .

A first electrode of the third transistor T3 is connected to the third data test line DG, and a second electrode of the third transistor T3 is connected to the third data line 143. Furthermore, a first switching signal line DSW is connected to the gates of the first transistor T1, the second transistor T2, and the third transistor T3 to control the connection and disconnection between the first data test line DR and the first data line 141, the connection and disconnection between the second data test line DB and the second data line 142, and the connection and disconnection between the third data test line DG and the third data line 143.
[0198] Arranged in this way, as shown in FIG21 , the first test circuit 161 includes a first data test line DR, a second data test line DB, a third data test line DG, and a first switch signal line DSW, which can receive data signals transmitted by an external circuit, thereby lighting up the first sub-pixel, the second sub-pixel, and the third sub-pixel, and detecting the circuits and signal lines in the array substrate 10. The structure is simple and the preparation cost is low.
[0199] That is, as shown in Figures 18, 19, and 20, when the test circuit 160 further includes test pads 164, and is connected to an external circuit via the test pads 164 to receive a test signal inputted by the external circuit, the first test circuit 161 can receive the required data signal by connecting to four test pads 164. This can reduce the number of test pads 164, facilitating the placement of the test pads 164 in an unused area on the array substrate 10, thereby simplifying the process and reducing manufacturing costs.
[0200] As shown in Figures 19, 20 and 22, the second test circuit 162 is connected to the plurality of scan lines 150 (see Figure 6A) and is configured to receive scan signals transmitted from an external circuit during a test phase.
[0201] 6A and 22 , scan line 150 includes a first scan line 151 and a second scan line 152 . Multiple scan output pads 1124 include multiple first scan output pads 1125 and multiple second scan output pads 1126 .
[0202] The first scan lines 151 are connected to the sub-pixels P in odd-numbered rows, and the second scan lines 152 are connected to the sub-pixels P in even-numbered rows. Furthermore, the array substrate 10 further includes first scan connection lines 171 and second scan connection lines 172 .

[0203] On this basis, as shown in FIG22 , the second test circuit 162 includes a first scan test line SG, a second scan test line DS, a fourth transistor T4, a fifth transistor T5, and a second switch signal line SSW. The first scan test line SG is configured to transmit a scan signal for lighting up the sub-pixels P in odd-numbered rows.

[0205] It should be noted that, as shown in FIG. 21 and FIG. 22 , the second switch signal line SSW and the first switch signal line DSW may be the same signal line, so as to simplify the circuit structure and reduce the manufacturing cost.
[0206] Arranged in this manner, as shown in FIG19 and FIG22 , the second test circuit 162 includes a first scanning test line SG and a second scanning test line DS, which can receive a scanning signal transmitted by an external circuit, thereby lighting up the first sub-pixel, the second sub-pixel, and the third sub-pixel, and detecting the circuits and signal lines in the array substrate 10. The structure is simple and the preparation cost is low.
[0207] That is, as shown in Figures 19 and 22, when the test circuit 160 further includes test pads 164, and is connected to an external circuit via the test pads 164 to receive a test signal inputted by the external circuit, the second test circuit 162 can receive the required scan signal by connecting to two test pads 164. This can reduce the number of test pads 164, facilitating the placement of the test pads 164 in an unused area on the array substrate 10, thereby simplifying the process and reducing manufacturing costs.
[0208] In some other embodiments, referring to FIG. 6B , the array substrate 10 includes a gate driving circuit 180 and a gate control signal line 173 , and the gate driving circuit 180 is disposed in the third border area B3 or the fourth border area B4 .

[0210] On this basis, the second test circuit 162 includes a plurality of gate control test lines 174, which are connected to the scan output pads 1124. The gate control test lines 174 are configured to transmit gate control signals for lighting up the sub-pixels P.
[0211] When set up in this manner, as shown in Figures 6B and 25, when the test circuit 160 also includes a test pad 164, and an external circuit is connected through the test pad 164 to receive a test signal input by the external circuit, each scan output pad 1124 connected to the gate control test line 174 must be connected to a corresponding test pad 164.
[0212] 6B , 16 and 19 , the first test signal line 163 is connected to the common electrode 23 of the plurality of sub-pixels P. The first test signal line 163 is configured to transmit a common voltage signal.
[0213] The plurality of driving pads 110 include a common voltage pad GND, which is connected to the common electrode 23 of the plurality of sub-pixels P. The first test signal line 163 is connected to the common voltage pad GND.

Here, the test pad 164 can be provided on the array substrate 10 or on the outside of the array substrate 10, and after the test is completed, the outer portion of the array substrate 10 is cut.

Among them, four test pads 164 are connected to the first test circuit 161, two test pads are connected to the second test circuit 162, and one test pad 164 is connected to the first test signal line 163. In this case, the number of test pads 164 is small, which facilitates setting the test pads 164 in an idle area on the array substrate 10, thereby simplifying the process and reducing the manufacturing cost.
[0217] 6B , 23 , and 24 , when the array substrate 10 includes the gate drive circuit 180 and the gate control signal line 173 , and the second test circuit 162 includes a plurality of gate control test lines 174 , the number of the test pads 164 is 20 to 40. For example, the number of the test pads 164 is 26 to 32.
[0218] For example, as shown in FIG24 , the number of test pads 164 is 28. Four of the test pads 164 are connected to the first test circuit 161, 23 are connected to the second test circuit 162, and one is connected to the first test signal line 163. In this case, the gate drive circuit 180 is disposed in the third border region B3 and / or the fourth border region B4 of the array substrate 10, which can reduce the area of the chip placement region C and thereby reduce the area of the first border region B1, thereby facilitating a narrow-border design for the display device 1000.
[0219] Some embodiments of the present disclosure provide an array substrate 10, as shown in FIG6B and FIG18, in which the test circuit 160 further includes a first test pad 1641, which is disposed between the plurality of peripheral connection lines 130 and the display area A.
