AI Technical Summary
In existing electronic paper display devices, the communication module is usually located on the back of the electronic paper, which increases the thickness of the device and affects the design of a thinner and lighter device.
A clearance area is reserved on the array substrate for installing the communication module. The space utilization is optimized by using asymmetrically arranged detection lines and conductive parts, reducing the proportion of the wiring area and freeing up space for installing the communication module.
This achieves a thinner and lighter display device while avoiding interference from the communication module to the drive circuit, thus improving space utilization.

Array substrate, manufacturing method thereof, electronic paper and display device TECHNICAL FIELD
[0001] The present disclosure relates to the technical field of display, in particular to an array substrate, a manufacturing method thereof, electronic paper and a display device. BACKGROUND
[0002] Electronic paper, also known as digital paper, is a product combining the display features of ordinary paper and display screens. Existing printed products are mainly realized by paper, and with the rapid increase in paper consumption, great damage has been caused to the environment. In this case, electronic paper has emerged as the times require. The thickness of electronic paper can be comparable to that of ordinary paper, and it can replicate the display features of paper and be reused, so electronic paper is expected to replace existing paper-based file display means in the near future.
[0003] With the continuous development of electronic paper, the design specifications for electronic paper are also required to be higher and higher. For example, electronic price tags are generally about 2-3 inches in size, and when displaying the price of goods, in order to facilitate the unified management of multiple electronic price tags, the electronic price tag includes a communication module arranged on the back of the electronic paper to receive the price of goods through the communication module and display it on the electronic paper.

[0115] The electronic paper film 2 includes a plurality of microstructures, such as micro-cups or micro-capsules, and each microstructure includes a transparent liquid and a plurality of charged particles suspended in the transparent liquid, such as white charged particles and black charged particles, wherein the white charged particles can be negatively charged, and the black charged particles can be positively charged, or the black charged particles can be negatively charged, and the white charged particles can be positively charged.
[0116] The array substrate 1 is provided with a driving module 111, a conductive part 112 (silver glue point, etc.), and a driving circuit. The input end of the driving module 111 is connected to a single-chip microcomputer (such as through a flexible circuit board 115), the output end of the driving module 111 is connected to the conductive part 112 and the driving circuit (such as through a driving trace), and the conductive part 112 is connected to the common electrode layer 3 (such as direct bonding). In this way, the driving module 111 can output a driving signal to the conductive part 112 and the driving circuit under the control of the single-chip microcomputer to form an electric field on both sides of the electronic paper film 2, and then the charged particles in the microstructure are driven to move under the action of the electric field, so that the microstructure presents a corresponding color, and the display of the picture on the electronic paper 30 is realized.
[0117] It should be noted that the communication module included in the display device in the related art is usually arranged on the back of the electronic paper 30 (i.e., the side of the array substrate 1 away from the electronic paper film 2), which undoubtedly increases the thickness of the display device. In the embodiment of the present disclosure, an array substrate 1 is provided, which can reserve a clearance area B4 on the array substrate 1 to provide a mounting space for the communication module, so as to avoid the influence of the communication module on the normal display of the display device while realizing the thinness of the display device.
[0118] FIG. 2 shows a top view structural schematic diagram of an array substrate 1. As shown in FIG. 2, the array substrate 1 has a display area AA and a peripheral area BB, the peripheral area BB includes a trace area (not shown in the figure) and a frame area (not shown in the figure), and the trace area is located between the display area AA and the frame area. The display area AA has an array of driving circuits (not shown in the figure), the trace area has a driving trace (not shown in the figure), the driving trace extends to the display area AA and is connected to the driving circuit. The peripheral area BB includes a first side edge area B1 and a second side edge area B2, the frame area is provided with a driving module 111 located in the first side edge area B1, and a clearance area B4 is formed in the second side edge area B2, the driving module 111 is connected to the driving trace, the clearance area B4 occupies an area ratio of greater than or equal to 55% in the second side edge area B2, and the clearance area B4 is used to arrange a communication module. The trace area is provided with one conductive part 112 located in the second side edge area B2, the conductive part 112 is located at the end of the second side edge area B2, and the conductive part 112 is connected to the driving module 111.
[0119] In the embodiments of the present disclosure, only one conductive part 112 is arranged in the frame area of the array substrate 1 and located at the end of the second side area B2, so as to improve the space utilization of the array substrate 1 and reduce the area of the wiring area in the second side area B2. Thus, a larger area is left in the second side area B2 to form a clearance area B4, so as to reduce the influence of the communication module arranged in the clearance area B4 on the driving circuit and the like.
[0120] The peripheral area BB includes the first side area B1 and the second side area B2, which are respectively the areas between the display area AA on the array substrate 1 and the corresponding side edges of the array substrate 1, and the first side area B1 and the second side area B2 can be two side areas on any two sides of the display area AA on the array substrate 1. The wiring area is the area between the edge of the display area AA on the array substrate 1 and the outermost driving wiring away from the display area AA, and the wiring area can include a plurality of wiring sub-areas, each of which is arranged along the circumference of the display area AA, and the plurality of wiring sub-areas are spaced apart along the circumference of the display area AA. The frame area is the area outside the outermost driving wiring away from the display area AA, and when the wiring area includes a plurality of wiring sub-areas, the frame area includes the area between the adjacent two wiring sub-areas and adjacent to the display area AA. The clearance area B4 is located in the area where the frame area and the second side area B2 of the array substrate 1 overlap, so as to ensure that there is no driving wiring in the clearance area B4, thereby avoiding the interference of the display signal transmitted by the driving wiring with the communication module in the clearance area B4. The area ratio of the clearance area B4 in the second side area B2 can be 55%, 57%, 59%, 62%, 65%, 68%, 70%, 72%, and the like.
[0121] The driving wiring of the wiring area includes a first voltage signal line, a second voltage signal line, a gate line and a data line. One end of the first voltage signal line, the gate line and the data line is extended from the wiring area to the frame area and connected with the driving module 111, and the other end of the first voltage signal line, the gate line and the data line is extended from the wiring area to the display area AA and connected with the driving circuit. One end of the second voltage signal line is connected with the conductive part 112, and the other end of the second voltage signal line is extended from the wiring area to the frame area and connected with the driving module 111.
[0122] The driving circuit includes a switching device (such as a thin film transistor) and a capacitor. The control electrode of the switching device is connected with the gate line for loading a scanning signal, the first electrode of the switching device is connected with the data line for loading a driving signal, and the second plate of the capacitor is connected with the first voltage signal line for loading a first voltage signal. In this way, the gate line can control the switching device to be turned on when the driving circuit loads the scanning signal, and the data line can load the driving signal to the switching device when the driving circuit loads the driving signal, so as to load the voltage on the side of the electronic paper film 2 close to the array substrate 1.
[0123] In some embodiments, as shown in FIG. 1, the array substrate 1 comprises a substrate 11, and sequentially stacked on the substrate 11 are a gate metal layer 12, a gate insulating layer 13, a semiconductor layer 14, a source-drain metal layer 15, a planarization layer 16, and a pixel electrode layer 17.
[0124] The substrate 11 can be a glass substrate, a quartz substrate, a plastic substrate, or other hard or flexible substrate, which can be a single-layer or multi-layer structure. Taking the multi-layer structure as an example, the substrate 11 comprises a first polyimide layer, a first protective layer, a second polyimide layer, and a second protective layer, which are sequentially stacked from bottom to top. The two protective layers are used to protect the polyimide layers from damage caused by subsequent processes. The second protective layer further covers a buffer layer, which can block water and oxygen and block alkali ions.
[0125] The driving wires described above can be a plurality of first voltage signal lines and a plurality of gate lines provided on the gate metal layer 12, and a plurality of data lines and a second voltage signal line provided on the source-drain metal layer 15. The switching devices and the capacitor included in the driving circuit described above can be that the gate metal layer 12 comprises a first conductive part and a second conductive part, the first conductive part forms a control electrode of the switching device, the second conductive part forms a second electrode plate of the capacitor, and the first conductive part is connected with the gate line, and the second conductive part is connected with the first voltage signal line; the semiconductor layer 14 comprises an active part, the active part comprises a channel region coinciding with the first conductive part, and connection parts on both sides of the channel region; the source-drain metal layer 15 comprises a third conductive part, a fourth conductive part, and a fifth conductive part, the third conductive part and the fourth conductive part form a first electrode and a second electrode of the switching device respectively, and the fifth conductive part forms a first electrode plate of the capacitor, the third conductive part and the fourth conductive part directly cover the connection parts on both sides of the channel region of the active part respectively, and the third conductive part is connected with the data line, and the fourth conductive part is connected with the fifth conductive part and the pixel electrode layer 17 respectively.
[0126] In the embodiments of the present disclosure, as shown in FIG. 2, the array substrate 1 is provided with a first positioning mark D1 and a second positioning mark D2 located in the peripheral area BB. One of the first positioning mark D1 and the second positioning mark D2 can be a cross mark, and the cross point of the cross mark is used for positioning, and the other can be an L-shaped mark, and the inner side of the L-shaped mark is used for positioning.
[0127] The first positioning mark D1 can be located in the second side edge area B2 to position the electronic paper film 2 when the electronic paper film 2 is fixed on the array substrate 1; and the second positioning mark D2 can be located in the second side edge area B2 to position the protective film 4 when the protective film 4 is fixed on the side of the common electrode layer 3 away from the array substrate 1. The positions of the first positioning mark D1 and the second positioning mark D2 can be set according to the corner positions of the wiring area in the second side edge area B2, and the first positioning mark D1 is located in the wiring area of the second side edge area B2, and the second positioning mark D2 is located in the frame area of the second side edge area B2, so that after the electronic paper film 2 is fixed on the array substrate 1 and the protective film 4 is fixed on the side of the common electrode layer 3 away from the array substrate 1, the protective film 4 can cover the entire electronic paper film 2, thereby effectively protecting the electronic paper film 2.
[0128] In addition, for the first positioning mark D1 and the second positioning mark D2 on the array substrate 1, one end of the second side edge area B2 can have a first pair of positioning marks including the first positioning mark D1 and the second positioning mark D2, or as shown in FIG. 2, both ends of the second side edge area B2 (the positions of the second side edge area B2 close to the left and right edges in the row direction X of the array substrate 1) can have a first pair of positioning marks including the first positioning mark D1 and the second positioning mark D2, and a second pair of positioning marks. For the case that both ends of the second side edge area B2 have the first positioning mark D1 and the second positioning mark D2, the accuracy of the alignment of the electronic paper film 2 and the protective film 4 can be better guaranteed, and the production yield of the electronic paper 30 can be improved.
[0129] In the embodiment of the present disclosure, as shown in FIG. 3, the array substrate 1 can be obtained by cutting the array mother board 10, and before the array mother board 10 is cut, as shown in FIG. 3, the array mother board 10 has a detection line 20 extending in the row direction X, and the detection line 20 extends to each array substrate 1 and is connected with the driving module 111 included in each array substrate 1.
[0130] In this way, each array substrate 1 can be detected by the multiple rows of detection lines 20 on the array mother board 10, so as to improve the detection efficiency of the array substrate 1 while guaranteeing the production yield of the array substrate 1.
[0131] After the array mother board 10 is cut, the detection line 20 can be located in the frame area of the array substrate 1, that is, the frame area of the array substrate 1 has the detection line 20, and the detection line 20 is asymmetrically arranged along the center line of the array substrate 1 parallel to the column direction Y. In addition, the clearance area B4 and the detection line 20 do not have an overlapping region, that is, the clearance area B4 does not have the detection line 20, so as to avoid the influence of the signal transmitted by the detection line 20 on the communication module arranged in the clearance area B4.
[0132] The detection lines 20 are connected to the driving module 111, so that the detection signals transmitted by the detection lines 20 can be driven by the driving circuit in the display area AA of the array substrate 1 through the driving module 111. Each row of detection lines 20 corresponding to a row of array substrates 1 includes at least four detection lines 20 to realize the transmission of multiple detection signals (first voltage signal, switching signal, scanning signal and data signal). For example, each row of detection lines 20 corresponding to a row of array substrates 1 includes six detection lines 20, two of which transmit the switching signal and the first voltage signal, respectively, and the remaining four detection lines 20 transmit the scanning signals of odd rows and even rows, respectively, and the other two detection lines 20 transmit the data signals of odd columns and even columns, respectively.
[0133] Next, the detection lines 20 on the array motherboard 10 will be explained in combination with a single array substrate 1.
[0134] In order to facilitate the connection of the detection lines 20 and the driving traces in the trace area, the detection lines 20 can extend in the row direction X, so that after the array motherboard 10 is cut, the two side edge areas of the array substrate 1 in the column direction Y can have detection lines 20.
[0135] At this time, in combination with the first side edge area B1 of the array substrate 1 provided with the driving module 111 and the second side edge area B2 provided with the conductive part 112 and the clearance area B4, it can be as shown in FIG. 2 that the first side edge area B1 and the second side edge area B2 are two side edge areas of the array substrate 1 distributed in the column direction Y, or as shown in FIG. 4 that the first side edge area B1 and the second side edge area B2 are two adjacent side edge areas of the array substrate 1 (i.e. the first side edge area B1 is one side edge area of the array substrate 1 in the column direction Y, and the second side edge area B2 is one side edge area of the array substrate 1 in the row direction X).
[0136] For the case where the first side edge area B1 and the second side edge area B2 are distributed in the column direction Y, the area ratio of the clearance area B4 in the second side edge area B2 is greater than or equal to 65%, for example, the area ratio of the clearance area B4 in the second side edge area B2 is 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, etc.
[0137] For example, the first side edge region B1 is a lower side edge region, and the second side edge region B2 is an upper side edge region. In this case, the first side edge region B1 refers to a region between the display region AA on the array substrate 1 and a lower side edge of the array substrate 1, and the second side edge region B2 refers to a region between the display region AA on the array substrate 1 and an upper side edge of the array substrate 1. Alternatively, the first side edge region B1 is an upper side edge region, and the second side edge region B2 is a lower side edge region. In this case, the first side edge region B1 refers to a region between the display region AA on the array substrate 1 and an upper side edge of the array substrate 1, and the second side edge region B2 refers to a region between the display region AA on the array substrate 1 and a lower side edge of the array substrate 1.
[0138] In addition, as shown in FIG. 2 or FIG. 5, the detection line 20 includes a first detection line L1 and a second detection line L2. The first detection line L1 is located in a region where the frame region overlaps the first side edge region B1, and the second detection line L2 is located in a region where the frame region overlaps the second side edge region B2. The second detection line L2 and the first detection line L1 are connected to the driving module 111.
[0139] In some embodiments, as shown in FIG. 2 or FIG. 5, the second detection line L2 is asymmetrically arranged along a center line parallel to the column direction Y on the array substrate 1. In this way, by the asymmetrically arranged second detection line L2, the second side edge region B2 is avoided, and a larger clearance region B4 in the second side edge region B2 is ensured.
[0140] Of course, in addition to the asymmetrically arranged second detection line L2, the first detection line L1 can be located on one side of a center line parallel to the column direction Y on the array substrate 1 to achieve asymmetric arrangement of the detection line 20 in the frame region, which is not limited in the embodiments of the present disclosure.
[0141] In some embodiments, as shown in FIG. 2 or FIG. 5, the second detection line L2 includes a wire segment L25 extending along the row direction X, and the wire segment L25 overlaps the driving module 111 in the column direction Y on the array substrate 1. In this way, interference between the detection line 20 and the driving module 111 on the array substrate 10 can be avoided.
[0142] Optionally, as shown in FIG. 5, the wire segment L25 is located on a side of the clearance region B4 away from the display region AA, and the wire segment L25 overlaps the conductive part 112 in the column direction Y. In this case, the clearance region B4 can be formed between the wire segment L25 and the wire region, and a longer wire segment L25 facilitates the formation of a larger clearance region B4, which in turn facilitates the arrangement of the communication module in the clearance region B4.
[0143] Optionally, as shown in FIG. 2, the wire segment L25 is located at the side of the display area AA in the clearance area B4, and the wire segment L25 and the clearance area B4 are located at the same side of the conductive part 112. At this time, the clearance area B4 can be formed at the side of the wire segment L25 away from the display area AA, and the isolation of the wire area and the clearance area B4 can be achieved through the wire segment L25, so as to effectively avoid the influence of the communication module arranged in the clearance area B4.
[0144] In some embodiments, as shown in FIG. 2 or FIG. 5, the first detection line L1 has a first column break Y1, the second detection line L2 has a second column break Y2, the first column break Y1 and the second column break Y2 respectively extend to the adjacent side edges of the array substrate 1 along the column direction Y, i.e. the first column break Y1 and the second column break Y2 are respectively located at the upper edge and the lower edge of the array substrate 1, and the line connecting the first column break Y1 and the second column break Y2 is parallel to the column direction Y; the second detection line L2 has a first row break X1 and a second row break X2 extending to the side edges (left and right edges) of the array substrate 1 along the row direction X of the array substrate 1, and the line connecting the first row break X1 and the second row break X2 is parallel to the row direction X.
[0145] That is, the first detection line L1 has a first column break Y1 extending to the lower edge, and the second detection line L2 has a second column break Y2 extending to the upper edge. Thus, for the array-distributed array substrate 1, the connection between the first column break Y1 and the second column break Y2 on the adjacent two array substrates 1 can realize the bending design of the detection line 20, so as to avoid the case that the straight segment on the detection line 20 is too long. The second detection line L2 has a first row break X1 extending to the left edge and a second row break X2 extending to the right edge. Thus, for the array-distributed array substrate 1, the connection between the first row break X1 and the second row break X2 on the adjacent two array substrates 1 can realize the series connection between the multiple array substrates 1.
[0146] In combination with the above-mentioned case that the second side edge area B2 has the first pair of positioning marks and the second pair of positioning marks, the end of the second detection line L2 close to the first row break X1 can pass through the gap formed by the first pair of positioning marks, i.e. as shown in FIG. 2 or FIG. 5, the end of the second detection line L2 close to the first row break X1 passes through the gap between the first positioning mark D1 and the second positioning mark D2, and includes a right-angle bending structure, and the end of the second detection line L2 close to the second row break X2 is located at the periphery of the second pair of positioning marks. In this way, the interference between the second detection line L2 and the first pair of positioning marks and the second pair of positioning marks can be avoided, and the space utilization of the second detection line L2 can be improved, i.e. the space occupied by the second detection line L2 is reduced, so as to facilitate the increase of the area occupied by the clearance area B4.
[0147] In addition, in combination with the second detection line L2 described above, the trace segment L25 extending along the row direction X is located at the side of the display area AA in the clearance area B4, and the end of the second detection line L2 close to the second row break X2 can pass through the gap between the first positioning mark D1 and the second positioning mark D2 included in the second pair of positioning marks, so as to reduce the distance between the end of the second detection line L2 close to the second row break X2 and the trace area, thereby forming a larger clearance area B4 in the second side edge area B2.
[0148] It should be noted that in combination with the array of one row of detection lines 20 on the array mother board 10 corresponding to each row of array substrates 1, the frame area is provided with a plurality of first detection lines L1 located at the first side edge area B1, and a plurality of second detection lines L2 located at the second side edge area B2, and the number of first detection lines L1 is the same as the number of second detection lines L2, so as to facilitate the connection of the first column break Y1 of the first detection line L1 and the second column break Y2 of the second detection line L2 of the adjacent two array substrates 1.
[0149] In some embodiments, as shown in FIG. 2, the first detection line L1 includes a first segment of trace L11 in the shape of U, the first segment of trace L11 has a detection end, and the two ends of the first segment of trace L11 form two first column breaks Y1, and the detection end is connected with the driving module 111; the second detection line L2 has a first row break X1, a second row break X2 and two second column breaks Y2, the two second column breaks Y2 correspond to the two first column breaks Y1 one by one, and the connection line of the corresponding first column break Y1 and second column break Y2 is parallel to the column direction Y of the array substrate 1.
[0150] In this way, for the two array substrates 1 adjacent along the column direction Y, the connection of the first detection line L1 and the second detection line L2 can be realized through the two first column breaks Y1 of the first detection line L1 and the two second column breaks Y2 of the second detection line L2, and the U-shaped bending design on the detection line 20 is realized.
[0151] Among them, the detection end of the first segment of trace L11 is used to transmit one of the switch signal, the first voltage signal, the scanning signal and the data signal. For example, as shown in FIGS. 6 and 7, the frame area is provided with six first segments of trace L11 located at the first side edge area B1, so as to form six detection ends through the six first segments of trace L11, at this time, two detection ends in the six detection ends are used to respectively transmit the switch signal and the first voltage signal, two detection ends in the remaining four detection ends are used to respectively transmit the scanning signal of the odd row and the even row, and the other two detection ends are used to respectively transmit the data signal of the odd column and the even column.
[0152] Optionally, as shown in FIG. 2, the second detection line L2 includes a first sub-detection line L21 and a second sub-detection line L22, the first sub-detection line L21 and the second sub-detection line L22 are located on both sides of the conductive part 112 in the row direction X; the first sub-detection line L21 has a first row break X1 and one second column break Y2, and the second sub-detection line L22 has a second row break X2 and another second column break Y2. At this time, two array substrates 1 adjacent in the column direction Y can be connected with the two first column breaks Y1 of the first segment of the wire L11 respectively through the second column break Y2 of the first sub-detection line L21 and the second column break Y2 of the second sub-detection line L22, realizing the design of the U-shaped bend on the detection line 20.
[0153] Wherein, the second detection line L2 forms a gap through the first sub-detection line L21 and the second sub-detection line L22, and two second column breaks Y2 are formed through the two ends of the gap (i.e. one end of the first sub-detection line L21 and one end of the second sub-detection line L22). In combination with the above-mentioned case that the second side edge area B2 has a first pair of positioning marks and a second pair of positioning marks, the positional relationship between the first sub-detection line L21 and the first pair of positioning marks, and the positional relationship between the second sub-detection line L22 and the second pair of positioning marks can refer to the positional relationship between the two ends of the second detection line L2 and the first pair of positioning marks and the second pair of positioning marks respectively as described above. For example, the first sub-detection line L21 passes through the gap formed by the first pair of positioning marks, and includes at least one right-angled bend structure, and the end of the second sub-detection line L22 close to the second row break X2 is located on the periphery of the second pair of positioning marks.
[0154] As shown in FIGS. 6 and 7, the first segment of the wire L11 includes a first detection wire L111 and a first jumper L112, the first sub-detection line L21 includes a second detection wire L211, and the second sub-detection line L22 includes a third detection wire L221; in combination with the above-mentioned film layer structure of the array substrate 1, the gate metal layer 12 and / or the source-drain metal layer 15 has the first detection wire L111, the second detection wire L211 and the third detection wire L221, and the array electrode layer has the first jumper L112. The two ends of the first detection wire L111 respectively constitute two first column breaks Y1, one end of the first jumper L112 is connected with the first detection wire L111 through a via, and the other end of the first jumper L112 constitutes a detection end; the two ends of the second detection wire L211 respectively constitute a first row break X1 and one second column break Y2, and the two ends of the third detection wire L221 respectively constitute a second row break X2 and another second column break Y2.
[0155] The first detection wire L111, the second detection wire L211 and the third detection wire L221 can be single-layer wires or double-layer wires, and at least one of the first detection wire L111, the second detection wire L211 and the third detection wire L221 is a wire in the same layer, so as to facilitate the series connection of the detection lines 20 on the two adjacent array substrates 1. When the first detection wire L111, the second detection wire L211 and the third detection wire L221 are single-layer wires, the first detection wire L111, the second detection wire L211 and the third detection wire L221 can be single-layer wires of the gate metal layer 12. In this way, based on the arrangement of the gate insulating layer 13 and the planarization layer 16, the distance between the communication module and the detection line 20 in the thickness direction of the array substrate 1 can be increased, and the electrical coupling between the detection line 20 and the communication module can be effectively avoided.
[0156] In some embodiments, as shown in FIG. 8, the detection line 20 further includes a third detection line L3 located in the overlapping area of the frame region and the first side region B1; the first detection line L1 further includes a second segment wire L12 located on both sides of the first segment wire L11 along the row direction X with the third detection line L3; the first segment wire L11 has a first detection end, the second segment wire L12 is connected with the first segment wire L11 and has a third row break X3 extending to the adjacent side edge (left edge) of the array substrate 1 along the row direction X, the third detection line L3 has a fourth row break X4 extending to the adjacent side edge (right edge) of the array substrate 1 along the row direction X and a second detection end, the first detection end and the second detection end are connected with the driving module 111, and the connection line of the third row break X3 and the fourth row break X4 is parallel to the row direction X.
[0157] In this way, the first detection end can be arranged on the first segment wire L11, and the second detection end can be arranged on the third detection line L3, so as to realize the dispersed arrangement of multiple detection ends and avoid the mutual influence of multiple detection ends due to the concentration. For example, as shown in FIG. 8, the frame region is provided with six first detection lines L1 and six third detection lines L3 in the first side region B1, so as to form three first detection ends through three first segment wires L11 in the six first segment wires L11 and form three second detection ends through three third detection lines L3 in the six third detection lines L3. At this time, the three first detection ends are used to transmit the switch signal, the even row scan signal and the even column data signal respectively, and the three second detection ends are used to transmit the first voltage signal, the odd row scan signal and the odd column data signal respectively.
[0158] In combination with the above-mentioned case that the detection lines 20 are asymmetrically arranged along the middle line parallel to the column direction Y on the array substrate 1, when the detection lines further include a third detection line L3, in addition to the second detection line L2 being asymmetrically arranged, the first detection line L1 and the third detection line L3 can also be asymmetrically arranged about the middle line parallel to the column direction Y on the array substrate 1, so as to achieve the asymmetric arrangement of the detection lines 20 in the frame area, and the present disclosure does not limit this.
[0159] As shown in FIGS. 9 and 10, the second segment of the wiring L12 includes a fourth detection wiring L121, and the third detection line L3 includes a fifth detection wiring L31 and a second jumper L32; in combination with the above-mentioned film layer structure of the array substrate 1, the gate metal layer 12 and / or the source-drain metal layer 15 have the fourth detection wiring L121 and the fifth detection wiring L31, and the array electrode layer has the second jumper L32; one end of the fourth detection wiring L121 is connected to the first segment of the wiring L11 (the first detection wiring L111), and the other end constitutes a third row of breaks X3; one end of the fifth detection wiring L31 constitutes a fourth row of breaks X4; one end of the second jumper L32 is connected to the fifth detection wiring L31 through a via, and the other end of the second jumper L32 constitutes a second detection end.
[0160] The fourth detection wiring L121 and the fifth detection wiring L31 can be single-layer wiring or double-layer wiring, and at least one of the fourth detection wiring L121 and the fifth detection wiring L31 includes a same-layer wiring, so as to facilitate the series connection of the detection lines 20 on two adjacent array substrates 1. When the fourth detection wiring and the fifth detection wiring L31 are single-layer wiring, the fourth detection wiring L121 and the fifth detection wiring L31 can be single-layer wiring of the gate metal layer 12.

[0172] For the case that the first side edge region B1 and the second side edge region B2 are adjacent, the area ratio of the clearance region B4 in the second side edge region B2 is greater than or equal to 65%, for example, the area ratio of the clearance region B4 in the second side edge region B2 is 65%, 66%, 67%, 68%, 69%, 70%, etc.
[0173] For example, the first side edge region B1 is the lower side edge region, and the second side edge region B2 is the right side edge region, at this time, the first side edge region B1 refers to the region between the display region AA on the array substrate 1 and the lower side edge of the array substrate 1, and the second side edge region B2 refers to the region between the display region AA on the array substrate 1 and the right side edge of the array substrate 1; or the first side edge region B1 is the upper side edge region, and the second side edge region B2 is the left side edge region, at this time, the first side edge region B1 refers to the region between the display region AA on the array substrate 1 and the upper side edge of the array substrate 1, and the second side edge region B2 refers to the region between the display region AA on the array substrate 1 and the left side edge of the array substrate 1.

[0175] When the first side edge region B is the lower side edge region, the third side edge region B3 is the upper side edge region, and the third side edge region B3 refers to the region between the display region AA on the array substrate 1 and the upper side edge of the array substrate 1; when the first side edge region B is the upper side edge region, the third side edge region B3 is the lower side edge region, and the third side edge region B3 refers to the region between the display region AA on the array substrate 1 and the lower side edge of the array substrate 1.
[0176] In this way, the detection lines 20 (fifth detection line L5, sixth detection line L6, seventh detection line L7) are arranged in the first side edge area B1 and the third side edge area B3 to save the space of the second side edge area B2, and further increase the area of the clearance area B4 on the basis of the second side edge area B2 having only one conductive part 112, so as to reduce the influence of the communication module arranged in the clearance area B4 on the driving circuit and the like.
[0177] The fifth detection line L5, the sixth detection line L6, and the seventh detection line L7 can all be multiple detection lines 20, and the number of detection lines 20 is completely the same. The multiple fifth detection lines L5, the multiple sixth detection lines L6, and the multiple seventh detection lines L7 all include switch detection lines 20, voltage detection lines 20, data detection lines 20, and scanning detection lines 20, and the switch detection lines 20 and the scanning detection lines 20 in the multiple fifth detection lines L5 are connected with the first sub-module 113 (such as a source sub-module). The switch detection lines 20, the voltage detection lines 20, and the data detection lines 20 in the multiple sixth detection lines L6 are connected with the second sub-module 114 (such as a gate sub-module).

[0180] In some embodiments, as shown in FIG. 4 or FIG. 16, the seventh detection line L7 is asymmetrically arranged along the center line parallel to the column direction Y on the array substrate 1.
[0181] Of course, in addition to the seventh detection line L7 being asymmetrically arranged, the fifth detection line L5 and the sixth detection line L6 can also be asymmetrically arranged along the center line parallel to the column direction Y on the array substrate 1, which is not limited in the embodiments of the present disclosure.
[0182] In some embodiments, as shown in FIG. 4, the fifth detection line L5 and the seventh detection line L7 each have a side edge (lower edge, upper edge) extending to the array substrate 1 along the column direction Y and connected with a column break (third column break Y3 and fourth column break Y4) parallel to the column direction Y, the fifth detection line L5 and the sixth detection line L6 each have a side edge (left edge, right edge) extending to the array substrate 1 along the row direction X and connected with a row break (seventh row break X7 and eighth row break X8) parallel to the row direction X, and the seventh detection line L7 has two side edges (left edge, right edge) extending to the array substrate 1 along the row direction X and connected with a row break (fifth row break X5 and sixth row break X6) parallel to the row direction X.

[0184] Among them, the second sub-module 114 is located between the first sub-module 113 and the sixth detection line L6 to ensure that the sixth detection line L6 has a row break extending to the right edge along the row direction X; the column breaks of the fifth detection line L5 and the seventh detection line L7 can be one or two, etc.
[0185] As an example, the fifth detection line L5 and the seventh detection line L7 each have two column breaks, as shown in FIG. 4, the fifth detection line L5 includes a third segment of the trace L51 and a U-shaped fourth segment of the trace L52, the fourth segment of the trace L52 is located between the third segment of the trace L51 and the first sub-module 113, and the sixth detection line L6 is located on a side of the second sub-module 114 away from the first sub-module 113; the two ends of the fourth segment of the trace L52 form two third column breaks Y3 extending to the adjacent side edge (lower edge) on the array substrate 1 in the column direction Y, the third segment of the trace L51 is connected with the fourth segment of the trace L52 and has a fifth row break X5 extending to the adjacent side edge (left edge) on the array substrate 1 in the row direction X, the sixth detection line L6 has a sixth row break X6 extending to the adjacent side edge (right edge) on the array substrate 1 in the row direction X, and the seventh detection line L7 has two fourth column breaks Y4 extending to the adjacent side edge (upper edge) on the array substrate 1 in the column direction Y, and a seventh row break X7 and an eighth row break X8 extending to the two side edges (left edge and right edge) on the array substrate 1 in the row direction X; the two third column breaks Y3 correspond to the two fourth column breaks Y4, and the connecting line of the corresponding third column break Y3 and the fourth column break Y4 is parallel to the column direction Y, the connecting line of the fifth row break X5 and the sixth row break X6, and the connecting line of the seventh row break X7 and the eighth row break X8 are all parallel to the row direction X.
[0186] In this way, by connecting the two third column breaks Y3 of the third segment of the trace L51 and the fourth segment of the trace L52 with the two fourth column breaks Y4 of the seventh detection line L7, the connection of the adjacent array substrates 1 in the column direction Y is realized, and at the same time, the bending design of the detection line 20 is realized, avoiding the case that the straight line segment on the detection line 20 is too long. In addition, by the fifth row break X5 of the third segment of the trace L51, the sixth row break X6 of the sixth detection line L6, and the seventh row break X7 and the eighth row break X8 of the seventh detection line L7, the connection of the adjacent array substrates 1 in the row direction X is realized, thereby facilitating the one-time detection of multiple array substrates 1.
[0187] Among them, the connection of the third segment of the trace L51 and the fourth segment of the trace L52 can refer to the connection of the first segment of the trace L11 and the second segment of the trace L12 described above, and as an example, the third segment of the trace L51 and the fourth segment of the trace L52 can be connected by a jumper; the two fourth column breaks Y4 of the seventh detection line L7 can refer to the two second column breaks Y2 formed by the second detection line L2 described above; the connection of part of the traces included in the plurality of fourth segments of the trace L52 in the plurality of fifth detection lines L5 and the first sub-module 113, and the connection of part of the detection lines 20 in the plurality of sixth detection lines L6 and the second sub-module 114 can refer to the connection of the first segment of the trace L11, the third detection line L3 and the driving module 111 described above, and the present disclosure will not be repeated here.

[0189] Since the seventh detection wiring L521, the eighth detection wiring L511 and the ninth detection wiring L61 are all far away from the clearance B4, they can all be set as double-layer wirings to reduce the resistance of signal transmission without affecting the communication module. For example, as shown in FIGS. 19 and 20, the seventh detection wiring L521 and the eighth detection wiring L511 each include double-layer wirings in the gate metal layer 12 and the source-drain metal layer 15, and the connection between the seventh detection wiring L521 and the sixth jumper L522 is shown in FIG. 19, and the connection between the seventh detection wiring L521 and the eighth detection wiring L511 through the seventh jumper L512 is shown in FIG. 20.

The seventh detection line L7 is located at a position of a film layer on the array substrate 1, which can refer to the tenth detection line L71 described above, and the disclosure will not be described again.
[0201] In some other embodiments, the seventh detection line L7 extends to both side edges (left edge and right edge) of the array substrate 1 along the row direction X and has a pair of row breaks parallel to the row direction X. The fifth detection line L5 and the seventh detection line L7, and the sixth detection line L6 and the seventh detection line L7 each have at least one pair of column breaks extending to the adjacent side edge (lower edge and upper edge) of the array substrate 1 along the column direction Y and parallel to the column direction Y.
