[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.
[0035] In order to achieve borderless or narrow borders, existing display panels usually wind the data lines that provide data signals to the display area to the back of the display panel, which makes the data lines outside the display area have a greater risk of disconnection. When the data lines cannot receive signals normally, the display panel will show a picture with bright and dark lines, resulting in unqualified products. If a product is scrapped due to one or two bright and dark lines, it will greatly increase the production line cost.
[0036] To solve the above problems, an embodiment of the present invention provides a display panel, including a first area and a second area, at least the first area includes sub-pixels; the display panel also includes multiple data signal lines and at least one repair signal line, the data signal line passes through the first area and extends to the second area; the repair signal line is located in the second area; in the second area, at least part of the data signal line and the repair signal line form an overlapping area; in the overlapping area, the data signal line and the repair signal line are arranged in different layers, and the extension directions intersect.
[0037] By adopting the above technical solution, a repair signal line is set in the second area of the display panel, and at least part of the data signal line and the repair signal line form an overlapping area, and in the overlapping area, the data signal line and the repair signal line are set in different layers. In this way, when an abnormal working state of the data signal line is detected, the data signal line and the repair signal line can be electrically connected at the overlapping area by laser melting or the like, and then the data signal is transmitted to the data signal line through the repair signal line, thereby realizing the repair of the data signal line, thereby reducing production line losses and improving product qualification rate.
[0038] The above is the core idea of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention. The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.
[0039] Figure 1 A schematic diagram of the structure of a display panel provided by an embodiment of the present invention is shown in FIG. Figure 1 As shown, the display panel 100 includes a first area 01 and a second area 02, at least the first area 01 includes a sub-pixel 30; the display panel 100 also includes a plurality of data signal lines 10 and at least one repair signal line 20; the data signal line 10 passes through the first area 01 and extends to the second area 02. The repair signal line 20 is located in the second area 02. In the second area 02, at least part of the data signal line 10 and the repair signal line 20 form an overlapping area; in the overlapping area, the data signal line 10 and the repair signal line 20 are arranged in different layers, and the extension directions intersect.
[0040] Among them, at least the first area 01 includes a sub-pixel 30, which can be understood as at least the first area 01 is used for display. Specifically, the sub-pixel 30 includes an electrically connected pixel circuit and a light-emitting element, and the pixel circuit is used to drive the light-emitting element to emit light to achieve a display function. The light-emitting element is at least arranged in the first area 01, so that at least the first area 01 can be used for display. The pixel circuit can be any pixel circuit known to those skilled in the art composed of devices such as transistors and capacitors. The specific type is not limited in the embodiment of the present invention. The light-emitting element can be a light-emitting diode, including but not limited to micro LED, OLED and mini LED.
[0041] The second area 02 may be located on at least one side of the first area 01. Figure 1 The second area 02 is arranged around the first area 01. In this embodiment, the second area 02 is provided with a repair signal line 20 for repairing the data signal line 10. Therefore, at least part of the second area 02 can be adjacent to the first area 01 in the extension direction of the data signal line 10.
[0042] For example, refer to Figure 1 In the extension direction of the data signal line 10, the upper end of the data signal line 10 is suspended, and the optional second area 02 is at least located above the first area 01. In this way, the end of the data signal line 10 can form an overlapping area with the repair signal line 20, and the interference between the repair signal line 20 and other line structures can also be reduced.
[0043] Specifically, the data signal line 10 is electrically connected to the pixel circuit, and is used to provide a data signal to the pixel circuit, so that the pixel circuit controls the light-emitting state of the light-emitting element based on the data signal. A data signal line 10 can be electrically connected to at least one column of sub-pixels 30. Therefore, if the data signal line 10 cannot normally receive the data signal, poor light and dark lines will occur. In this embodiment, a repair signal line 20 is set in the second area 02, and at least part of the data signal line 10 overlaps with the repair signal line 20 and is set in a different layer. In this way, when it is detected that the data signal line 10 is working abnormally, the data signal line 10 can be electrically connected to the repair signal line 20 at the overlapping area by laser melting or the like, and then the data signal is transmitted to the data signal line 10 through the repair signal line 20, so as to repair the data signal line, thereby reducing the production line loss and improving the product qualification rate.
[0044] It should be noted that at least part of the data signal lines 10 and the repair signal lines 20 form an overlapping area, that is, part of the data signal lines 10 and the repair signal lines 20 may form an overlapping area; or all the data signal lines 10 and the repair signal lines 20 may form an overlapping area. Figure 1 Only a part of the data signal lines 10 and the repair signal lines 20 form an overlapping area. The part of the data signal lines may be data signal lines 10 with a higher probability of abnormal operation determined by experience, and may be set according to actual needs. Figure 2 A schematic diagram of the structure of another display panel provided by an embodiment of the present invention is shown in FIG. Figure 2 As shown, each data signal line 10 forms an overlapping area with the repair signal line 20 , so that when any data signal line 10 is abnormal, the repair signal line 20 can be used to repair the data signal line 10 .
[0045] It should be noted that one repair signal line 20 can repair at least one data signal line 10. Specifically, for data signal lines that always transmit the same signal, if such data signal lines work abnormally, the same repair signal line can be used to repair multiple data signal lines at the same time; for data signal lines that transmit different signals, different repair signal lines need to be used to repair them respectively.
[0046] It can be understood that the more abnormal data signal lines that transmit different signals, the more repair signal lines are required. In order to avoid repairing too many signal lines and occupying too large an area, you can define a threshold for the number of repair signal lines. If the number of abnormal data signal lines to be repaired exceeds the threshold, the repair process will no longer be carried out and the signal lines will be scrapped directly.
[0047] The technical solution of the embodiment of the present invention is to set a repair signal line in the second area of the display panel, and make at least part of the data signal line and the repair signal line form an overlapping area, and in the overlapping area, the data signal line and the repair signal line are set in different layers. In this way, when it is detected that the data signal line is working abnormally, the data signal line and the repair signal line can be electrically connected at the overlapping area by laser melting or the like, and then the data signal is transmitted to the data signal line through the repair signal line, so as to realize the repair of the data signal line, thereby reducing the production line loss and improving the product qualification rate.
[0048] Figure 1 and Figure 2 Only the structure of the first area 01 including the sub-pixel 30 in the display panel 100 is shown. At this time, the first area 01 is used for display, and the second area 02 is the frame area of the display panel 100. In other optional embodiments, the second area 02 of the display panel 100 can also be used for display. Figure 3 A structural diagram of another display panel provided by an embodiment of the present invention is shown in FIG. Figure 3 As shown, the sub-pixel 30 in the display panel 100 includes a first sub-pixel 301 and a second sub-pixel 302, the first sub-pixel 301 includes a first light-emitting element 311 and a first pixel circuit 312, and the second sub-pixel 302 includes a second light-emitting element 321 and a second pixel circuit 322; the first light-emitting element 311, the first pixel circuit 312 and the second pixel circuit 322 are all located in the first area 01; the second light-emitting element 321 is located in the second area 02.
[0049] The first pixel circuit 312 is electrically connected to the first light-emitting element 311, and the first pixel circuit 312 is used to provide a driving signal to the first light-emitting element 311 to drive the first light-emitting element 311 to emit light. The second pixel circuit 322 is electrically connected to the second light-emitting element 321, and the second pixel circuit 322 is used to provide a driving signal to the second light-emitting element 321 to drive the second light-emitting element 321 to emit light.
[0050] In this embodiment, since light-emitting elements are disposed in both the first region 01 and the second region 02, both the first region 01 and the second region 02 can be used for display, thereby realizing a borderless full-screen display design. In addition, by disposing the first pixel circuit 312 for controlling the first light-emitting element 311 and the second pixel circuit 322 for controlling the second light-emitting element 321 to emit light in the first region 01, it is beneficial to arrange the signal lines and other circuit structures in the second region 02.
[0051] It should be noted that Figure 1-Figure 2 Only a structure in which one data signal line 10 and the repair signal line 20 form an overlapping area is shown. In other optional embodiments, one data signal line 10 may also form two or more overlapping areas with the repair signal line 20. In this case, at least part of the overlapping areas may be selected for data repair. In other words, any one of the overlapping areas may be selected for repair, or all overlapping areas may be repaired to improve the repair success rate.
[0052] Figure 4 for Figure 1 Schematic diagram of the enlarged structure of area A0, see Figure 4 Optionally, near the overlapping area between the data signal line 10 and the repair signal line 20, the data signal line 10 extends along the second direction Y, and the repair signal line 20 extends along the first direction X, so that the data signal line 10 and the repair signal line 20 form an overlapping area P0. In other optional embodiments, the data signal line 10 can be configured to include a portion extending along the first direction X and a portion extending along the second direction Y, and the repair signal line 20 can be configured to include a portion extending along the first direction X and a portion extending along the second direction Y, so that the data signal line 10 can form one or more overlapping areas with the repair signal line 20.
[0053] Optional, Figure 5 A schematic diagram of a partial top view of a film layer structure of a display panel provided in an embodiment of the present invention is provided, and a schematic diagram of the film layer structure near the overlapping area of the data signal line 10 and the repair signal line 20 is provided (the same below). Figure 5 As shown, the repair signal line 20 includes a first main line portion 21 and a plurality of repair extension portions 23; the plurality of repair extension portions 23 are all electrically connected to the first main line portion 21; an extension direction of the repair extension portion 23 intersects with an extension direction of the first main line portion 21; the data signal line 10 includes a data main line portion 11 and a data extension portion 12; an extension direction of the data extension portion 12 intersects with an extension direction of the data main line portion 11; an extension direction of the first main line portion 21 intersects with an extension direction of the data main line portion 11; an extension direction of the repair extension portion 23 intersects with an extension direction of the data extension portion 12; at least the repair extension portion 23 forms an overlapping area with the data extension portion 12.
[0054] Specifically, by setting the repair signal line 20 to include a first main line portion 21 and a plurality of repair extension portions 23 electrically connected to the first main line portion 21, and setting the data signal line 10 to include a data main line portion 11 and a data extension portion 12 electrically connected to the data main line portion 11, and at least making the repair extension portion 23 overlap with the data extension portion 12, the repair extension portions 23 can be dispersedly arranged along the extension direction of the first main line portion 21 to disperse the overlapping areas corresponding to different data signal lines 10, thereby increasing the distance between two adjacent overlapping areas and preventing the distance between the two overlapping areas from being too close, resulting in the adjacent overlapping area being repaired when repairing one of the overlapping areas, thereby causing problems such as abnormal data transmission, thereby improving the repair reliability.
[0055] It should be noted that when the repair signal line 20 includes the first main line portion 21 and the repair extension portion 23, and the data signal line 10 includes the data main line portion 11 and the data extension portion 12, the relative position relationship between the first main line portion 21 and the data extension portion 12 and the data main line portion 11 can be set according to actual needs. Optionally, continuing with reference 5, the first main line portion 21 is located on the side of the data extension portion 12 away from the first area 01; the repair extension portion 23 and the data extension portion 12 form a first overlapping area P1, and the first main line portion 21 does not overlap with the data main line portion 11; the first overlapping area P1 is used for data repair.
[0056] Specifically, the data extension portion 12 is arranged on a side of the first main line portion 21 close to the first area 01, and the repair extension portion 23 is arranged on a side of the first main line portion 21 close to the first area 01, so as to reduce the electrical connection path between the data extension portion 12 and the data main line portion 11, and after the data extension portion 12 is repaired by using the repair extension portion 23 at the first overlapping area P1, the first main line portion 21 is electrically connected to the data main line portion 11 through the repair extension portion 23 and the data extension portion 12, so that the electrical connection path between the first main line portion 21 and the data main line portion 11 can be reduced, thereby reducing the line transmission impedance, reducing the electrical signal transmission attenuation, and improving the repair quality.
[0057] In another alternative embodiment, Figure 6 A schematic diagram of a partial top view of a film layer structure of another display panel provided in an embodiment of the present invention is shown in FIG. Figure 6 As shown, the first main line portion 21 is located on the side of the data extension portion 12 close to the first area 01; the repair extension portion 23 and the data extension portion 12 form a first overlapping area P1, and the first main line portion 21 and the data main line portion 11 form a second overlapping area P2; at least one of the first overlapping area P1 and the second overlapping area P2 is used for data repair.
[0058] Specifically, the first main line portion 21 is arranged on a side of the data extension portion 12 close to the first area 01, and the repair extension portion 23 is arranged on a side of the first main line portion 21 away from the first area 01, so that the part of the data main line portion 11 crossing the first main line portion 21 can form a second overlapping area P2 with the first main line portion 21, and the data extension portion 12 and the repair extension portion 23 form a first overlapping area P1, so as to increase the number of overlapping areas between the data signal line 10 and the repair signal line 20, and at least one of the overlapping areas can be selected for repair according to actual needs to improve the success rate of repair.
[0059] It is understandable that the above description only takes the example that the repair extension portion 23 is located on the same side of the first main line portion 21 , and the repair extension portion 23 may also be located on both sides of the first main line portion 21 . Figure 7 A schematic diagram of a partial top view of a film layer structure of another display panel provided in an embodiment of the present invention is shown in FIG. Figure 7 As shown, optionally, the repair extension portion 23 includes a first extension portion 231 and a second extension portion 232, the first extension portion 231 is located on a side of the first main line portion 21 close to the first area 01, the second extension portion 232 is located on a side of the first main line portion 21 away from the first area 01, and the first extension portion 231 and the second extension portion 232 are alternately arranged along the extension direction of the first main line portion 21. In this way, of the two adjacent data signal lines 10, the data extension portion 12 and the first extension portion 231 in one of the data signal lines 10 form a first overlapping area P1, and in the other data signal line 10, the data extension portion 13 and the second extension portion 232 form a first overlapping area P1, and the data main line portion 11 and the first main line portion 21 form a second overlapping area P2. Since the first extension portion 231 and the second extension portion 232 are arranged on opposite sides of the first main line portion 21 and are alternately arranged, the dispersion of the overlapping areas corresponding to the two adjacent data signal lines 10 can be further increased, thereby improving the repair reliability.
[0060] It should be noted that Figure 5-Figure 7 Only the structure in which the data main line portion 11 and the data extension portion 12 are both located in the same film layer, and the structure in which the first main line portion 21 and the repair extension portion 23 are both located in the same film layer is shown. At this time, the vertical distance between the film layer where the first main line portion 21 is located and the film layer where the data main line portion 11 is located is defined as the first distance, and the vertical distance between the film layer where the repair extension portion 23 is located and the film layer where the data extension portion 12 is located is defined as the second distance, and the first distance is equal to the second distance. Therefore, no matter whether one or two overlapping areas are formed between the data signal line 10 and the repair signal line 20, the vertical distance between the data signal line 10 and the repair signal line 20 in each overlapping area is equal, and at least one of the overlapping areas can be selected to repair the data signal line 10 according to actual needs.
[0061] In addition, the film layers of the data main line portion 11, the data extension portion 12, the first main line portion 21 and the repair extension portion 23 may be arranged in other ways. Figure 8 A schematic diagram of a partial top view of a film layer structure of another display panel provided in an embodiment of the present invention, Fig. 9 For along Figure 8 The cross-sectional structure diagram of the display panel taken at B1-B1' in FIG. Figure 8 and Fig. 9 The vertical distance between the film layer where the first main line portion 21 is located and the film layer where the data main line portion 11 is located is a first distance d1; the vertical distance between the film layer where the repair extension portion 23 is located and the film layer where the data extension portion 12 is located is a second distance d2; the first distance d1 is greater than the second distance d2.
[0062] Optional, reference Figure 8 and Fig. 9 , when the first distance d1 is greater than the second distance d2; for the case where the repair extension portion 23 and the data extension portion 12 form the first overlapping area P1, and the data main line portion 11 and the first main line portion 21 form the second overlapping area P2, the first overlapping area P1 can be selected for data repair. Since the vertical distance (second distance d2) between the repair signal line and the data signal line at the first overlapping area P1 is smaller than the vertical distance (first distance d1) between the repair signal line and the data signal line at the second overlapping area P2, the laser energy required to connect the repair signal line 20 and the data signal line 10 at the first overlapping area P1 by laser melting is lower and less difficult, therefore, selecting the first overlapping area P1 for data repair can improve the success rate of repair.
[0063] Optionally, the first main line portion 21 and the repair extension portion 23 are arranged in different layers; and / or the data main line portion 11 and the data extension portion 12 are arranged in different layers, so that the second distance d2 between the repair extension portion 23 and the data extension portion 12 at the first overlapping area P1 is smaller than the first distance d1 between the first main line portion 21 and the data main line portion 11 at the second overlapping area P2.
[0064] Optional, reference Figure 8 and Fig. 9 , the repair extension portion 23 is located in the first metal layer M1; the first main line portion 21 and the data extension portion 12 are both located in the second metal layer M2; the data main line portion 11 is located in the third metal layer M3; the display panel 100 includes a substrate 010, the second metal layer M2 is located on a side of the first metal layer M1 away from the substrate 010, and the third metal layer M3 is located on a side of the second metal layer M2 away from the substrate 010.
[0065] Specifically, the first main line portion 21 and the data extension portion 12 have the same extension direction. The first main line portion 21 and the data extension portion 12 are both arranged in the second metal layer M2, so that the number of metal layers arranged can be reduced. In this embodiment, the data main line portion 11 located in the third metal layer M3 is switched to the data extension portion 12 located in the second metal layer M2, and the first main line portion 21 located in the second metal layer M2 is switched to the repair extension portion 23 located in the first metal layer M1, so that the second distance d2 between the data extension portion 12 and the repair extension portion 23 is smaller, and when the data signal line 10 is repaired at the first overlapping area P1, the repair reliability can be improved.
[0066] Reference Fig. 9 , taking the display panel as a micro LED display panel as an example, the display panel includes a light-shielding metal layer K1, a gate metal layer K2, a capacitor metal layer K3, a source-drain metal layer K4, a connecting metal layer K5 and a welding metal layer K6 which are sequentially stacked on the substrate 010, and further includes an active layer K0 located between the light-shielding metal layer K1 and the gate metal layer K2. Among them, the light-shielding metal layer K1 can be used to make a light-shielding metal to improve the luminous efficiency of the light-emitting element and reduce light loss. When the pixel circuit includes a dual-gate transistor, the light-shielding metal layer can also be used to make a bottom gate structure (g2). The active layer K0 can be used to form a channel for carrier flow in the transistor. The gate metal layer K2 can be used to form structures such as the top gate structure, scanning signal line and initialization signal line of the transistor. The capacitor metal layer K3 can be used to form structures such as capacitor plates. The source-drain metal layer K4 can be used to form the source-drain metal electrode of the transistor. The welding metal layer K6 can be used to form an anode pad and a cathode pad to be electrically connected to the light-emitting diode when the micro light-emitting diode is transferred in large quantities. The metal structure in the connecting metal layer K5 serves to connect the upper and lower metal layers. The data signal line in the display area can usually be set in the source and drain metal layer K4 or the connecting metal layer K5. Three of the metal layers can be selected as the first metal layer, the second metal layer and the third metal layer, as long as the second metal layer M2 is located on the side of the first metal layer M1 away from the substrate 010, the third metal layer M3 is located on the side of the second metal layer M2 away from the substrate 010, and the distance (second distance) between the second metal layer M2 (the film layer where the data extension part 12 is located) and the first metal layer M1 (the film layer where the repair extension part 23 is located) is less than the distance (first distance) between the third metal layer M3 (data main line part 11) and the second metal layer M2 (first main line part 21). Continue to refer to Figure 8 and Fig. 9The sub-pixel includes a pixel circuit 31, the pixel circuit 31 includes a first transistor Q1, the first transistor Q1 includes a first gate g1, a first electrode q1 and a second electrode q2; the display panel 100 includes an active layer K0, the first gate g1 is located on a side of the active layer K0 away from the substrate 010, and is located on the second metal layer M2; the first electrode q1 and the second electrode q2 are located on the third metal layer M3; the first metal layer M1 is located on a side of the active layer K0 away from the second metal layer M2.
[0067] in, Fig. 9 The first transistor Q1 shown in the figure can be, for example, a transistor in the pixel circuit electrically connected to the light emitting element. The first electrode q1 and the second electrode q2 are the source and drain of the first transistor Q1 respectively.
[0068] Reference Fig. 9 In this embodiment, the second metal layer M2 is the metal layer where the first gate g1 is located. Specifically, the first gate g1 is located on the side of the active layer K0 away from the substrate 010 and is a top gate structure. Therefore, in this embodiment, the gate metal layer K2 is selected as the second metal layer M2 for manufacturing the data extension part 12 and the first main line part 21. The extension directions of the first main line part 21 and the data extension part 12 are the same as the extension direction of the scanning signal line. The first gate g1, the scanning signal line, the data extension part 12 and the first main line part 21 are selected to be manufactured in the same layer, which can reduce the interference between different signal lines.
[0069] Reference Fig. 9 In this embodiment, the third metal layer M3 is the film layer where the first electrode q1 and the second electrode q2 are located, that is, the source-drain metal layer K4 is selected as the third metal layer M3 for manufacturing the data main line portion 11. Compared with the data main line portion 11 being arranged on the connecting metal layer K5, such an arrangement can reduce the difficulty of crossing the data main line portion 11 to the data extension portion 12. In addition, by manufacturing the first electrode q1 and the second electrode q2 in the same layer as the data main line portion 11, the data main line portion 11 can be reused as the first electrode q1 or the second electrode q2 in the third metal layer M3, so as to reduce the number of vias set in the display panel 100, simplify the manufacturing process of the display panel 100, and improve the manufacturing efficiency of the display panel 100.
[0070] Reference Fig. 9 In this embodiment, the first metal layer M1 is located on the side of the active layer K0 away from the second metal layer M2. The light-shielding metal layer K1 can be optionally used as the first metal layer M1 for making the repair extension portion to reduce the difficulty of crossing the first main line portion 21 to the repair extension portion 23.
[0071] Since the thickness of the dielectric layer between the source-drain metal layer K4 and the gate metal layer K2 is relatively thick, and the thickness of the dielectric layer between the gate metal layer K2 and the light-shielding metal layer K1 is relatively thin, in this embodiment, the source-drain metal layer K4 where the first pole q1 and the second pole q2 are located is used as the third metal layer M3, the gate metal layer K2 where the first gate g1 is located is used as the second metal layer M2, and the light-shielding metal layer K1 where the second gate g2 (bottom gate) is located is used as the first metal layer M1, so that the second distance d2 between the repair extension portion 23 and the data extension portion 12 at the first overlapping area P1 can be smaller than the first distance d1 between the first main line portion 21 and the data main line portion 11 at the second overlapping area P2.
[0072] Figure 8 Only the structure in which the first main line portion 21 and the repair extension portion 23 are arranged in different layers, and the structure in which the data main line portion 11 and the data extension portion 12 are arranged in different layers is shown. The film layer arrangement of the data main line portion 11, the data extension portion 12, the first main line portion 21 and the repair extension portion 23 can also be adopted in other ways. Optionally, Fig.10 A schematic diagram of a partial top view of a film layer structure of another display panel provided in an embodiment of the present invention is shown in FIG. Fig.10 As shown, the first main line portion 21 and the repair extension portion 23 are arranged in the same layer, and the data main line portion 11 and the data extension portion 12 are arranged in different layers.
[0073] Reference Fig. 9 and Fig.10 Optionally, the first main line portion 21 and the repair extension portion 23 are both located in the light-shielding metal layer K1, the data main line portion 11 is located in the source-drain metal layer K4, and the data extension portion 12 is located in the gate metal layer K2, so that the vertical distance between the repair extension portion 23 and the data extension portion 12 is smaller, so as to improve the repair success rate at the first overlapping area P1.
[0074] In other embodiments, the optional data main line portion 11 is located in the source-drain metal layer K4, the data extension portion 12 is located in the capacitor metal layer K3, and the first main line portion 21 and the repair extension portion 23 are both located in the gate metal layer K2.
[0075] In another alternative embodiment, Fig.11 A schematic diagram of a partial top view of a film layer structure of another display panel provided in an embodiment of the present invention is shown in FIG. Fig.11 As shown, optionally, the first main line portion 21 and the repair extension portion 23 are arranged in different layers, and the data main line portion 11 and the data extension portion 12 are arranged in the same layer.
[0076] Reference Fig. 9 and Fig.11The optional data main line portion 11 and the data extension portion 12 are both located in the source and drain metal layer K4, the first main line portion 21 is located in the gate metal layer K2, and the repair extension portion 23 is located in the capacitor metal layer K3, so that the vertical distance between the repair extension portion 23 and the data extension portion 12 is smaller, thereby improving the repair success rate at the first overlapping area P1.
[0077] It should be noted that the above description only provides an exemplary description of the film layer settings of the first main line portion 21, the repair extension portion 22, the data main line portion 11 and the data extension portion 12. The film layer position relationship of the first main line portion 21, the repair extension portion 22, the data main line portion 11 and the data extension portion 12 may also be other. On the premise that the core invention points of the embodiments of the present invention can be achieved, the embodiments of the present invention do not make specific limitations on this.
[0078] The above description is based on the example that the orthographic projection shape of the repair extension portion 23 on the light-emitting surface of the display panel 100 is I-shaped. In other optional embodiments, Fig.12 A schematic diagram of a partial top view of a film layer structure of another display panel provided in an embodiment of the present invention, Fig.13 A schematic diagram of a partial top view of a film layer structure of another display panel provided in an embodiment of the present invention, Fig.14 A schematic diagram of a partial top view of a film layer structure of another display panel provided in an embodiment of the present invention, referring to Figure 12-Figure 14 The orthographic projection shape of the repair extension portion 23 on the light emitting surface of the display panel 100 may also be at least one of a U-shape, a V-shape, a Y-shape and a W-shape; the opening side of the repair extension portion 23 forms an overlapping area with the data extension portion 12 .
[0079] Specifically, by setting the repair extension portion 23 to be U-shaped, V-shaped, Y-shaped or W-shaped, the overlapping area P1 formed by the repair extension portion 23 and the data extension portion 12 is increased. When the repair extension portion 23 is U-shaped, V-shaped or Y-shaped, the open side of the repair extension portion 23 can form two first overlapping areas P1 with the data extension portion 23, namely P11 and P12. After the data signal line 10 is repaired by using one of the first overlapping areas P1, if the data signal line 10 still does not resume normal operation, the data signal line 10 can be repaired again by using another first overlapping area P1, thereby improving the repair success rate. When the repair extension portion 23 is W-shaped, the opening side of the repair extension portion 23 can form three first overlapping areas P1 with the data extension portion 23, namely P11, P12 and P13, so that after one of the first overlapping areas P1 is used to repair the data signal line 10, if the data signal line 10 still does not resume normal operation, the other two first overlapping areas P1 can be used to repair the data signal line 10 again, thereby improving the repair success rate. In addition, when the repair extension portion 23 is W-shaped, the end of the repair extension portion 23 facing away from the opening side can be electrically connected to the first main line portion 21 through two through holes, so as to improve the electrical connection reliability between the repair extension portion 23 and the first main line portion 21, thereby improving the repair reliability.
[0080] Optional, Fig.15 A schematic diagram of the structure of another display panel provided by an embodiment of the present invention is shown in FIG. Fig.15 As shown, the display panel 100 also includes a signal lead-out pad 34 located in the second area 02; the repair signal line 20 includes a first main line portion 21 and at least one second main line portion 22; the extension direction of the first main line portion 21 intersects with the extension direction of the data signal line 10 in the first area 01; the extension direction of the second main line portion 22 intersects with the extension direction of the first main line portion 21, and the second main line portion 22 does not overlap with the data signal line 10; along the extension direction of the first main line portion 21, the first main line portion 21 includes a first end A1 and a second end A2 opposite to each other, and at least one of the first end A1 and the second end A2 is electrically connected to the second main line portion 22; along the extension direction of the second main line portion 22, the second main line portion 22 includes a third end A3 and a fourth end A4, the third end A3 is electrically connected to the first main line portion 21, and the fourth end A4 is electrically connected to the signal lead-out pad 34.
[0081] Specifically, the extension direction of the first main line portion 21 intersects with the extension direction of the data signal line 10, so that the data signal line 10 forms at least one overlapping area with the repair signal line 20 in the area where the first main line portion 21 is located, and the details can be referred to the above description. The extension direction of the second main line portion 22 intersects with the extension direction of the first main line portion 21, and the second main line portion 22 does not overlap with the data signal line 10, and the electrical signal can be transmitted to the first main line portion 21 through the second main line portion 22. Specifically, the signal lead pad 34 can be wound to the back of the display panel 100 through the side routing (not shown) to receive the signal. When the repair signal line 20 is enabled, the data signal can be transmitted to the data signal line 10 through the side routing, the signal lead pad 34, the second main line portion 22 and the first main line portion 21 in sequence, so as to repair the data signal line 10 and ensure the normal transmission of the data signal.
[0082] Understandably, Fig.15 It is only shown that the repair signal line 20 includes one second main line portion 22 . In other optional embodiments, the repair signal line 20 may also include two or more second main line portions 22 . Fig.16 A schematic diagram of the structure of a display panel provided by an embodiment of the present invention is shown in FIG. Fig.16 As shown, the repair signal line 20 includes two second main line parts 22, and the two second main line parts 22 are electrically connected to the first end A1 and the second end A2 of the first main line part 21, respectively. At this time, two signal connection pads 34 can be set, namely the first signal connection pad 341 and the second signal connection pad 342. The fourth end A4 of one second main line part 22 is electrically connected to the first signal connection pad 341, and the fourth end A1 of the other second main line part 22 is electrically connected to the second signal connection pad 342. With such a configuration, when the repair signal line 20 is enabled, the data signal can be transmitted to the first main line part 21 through the two second main line parts 22 at the same time, reducing the load.
[0083] Optional, Fig.17 A schematic diagram of the structure of another display panel provided by an embodiment of the present invention is shown in FIG. Fig.17 As shown, the display panel 100 includes at least two repair signal lines 20 ; the first main line portions 21 of the repair signal lines 20 are arranged side by side along the extending direction of the first main line portions 21 .
[0084] By arranging the first main line portions 21 of different repair signal lines 20 side by side along the extension direction of the first main line portions 21, different repair signal lines 20 can form overlapping areas with data signal lines 10 in different areas along the extension direction of the first main line portions 21, so that at least one data line 10 in the corresponding area can be repaired by one repair signal line 20, thereby increasing the number of repairable data signal lines 10 and improving the product qualification rate.
[0085] For example, Fig.17 Taking the display panel 100 including two repair signal lines 20 as an example, there is a gap between the two first main line portions 21 corresponding to the two repair signal lines 20, so that the data signal line 10 forming an overlapping area with the repair signal line 20 can be repaired by one of the repair signal lines 20, and the data signal line 10 forming an overlapping area with the repair signal line 20 can be repaired by the other repair signal line 20, and the two repair signal lines 20 can repair different data signal lines 10. For example, the repair signal line 20 on the left can repair at least one data signal line 10 in the left area, and the repair signal line 20 on the right can repair at least one data signal line 10 in the right area, thereby increasing the number of data signal lines 10 that can be repaired and improving the product qualification rate.
[0086] When the display panel includes three or more repair signal lines 20, and the first main line portions 21 of each repair signal line 20 are arranged side by side along the extension direction of the first main line portion 21, the second main line portion 22 connected to the first main line portion 21 located in the middle area can pass through the first area 01 and extend to the signal connection pad.
[0087] The above description only takes the example that the first main line portions 21 are arranged side by side along the extending direction of the first main line portions 21 . The first main line portions 21 may also be arranged side by side along the extending direction of the data signal line 10 . Fig.18 A structural diagram of another display panel provided by an embodiment of the present invention is shown in FIG. Fig.18 As shown, the display panel 100 includes at least two repair signal lines 20 ; the first main line portions 21 of the repair signal lines 20 are arranged side by side along the extending direction of the data signal lines 10 in the first area 01 .
[0088] In the present embodiment, since the first main line portions 21 of different repair signal lines 20 are arranged side by side along the extension direction of the data signal line 10 in the first area 01, the data signal lines 10 that can be repaired by different repair signal lines 20 are crossed. In this way, the data signal lines 10 that can be repaired by any repair signal line 20 are not restricted by the position of the data signal line 10, thereby improving the repair flexibility and improving the product qualification rate.
[0089] For example, Fig.18 Taking the display panel including two repair signal lines 20 as an example, assuming that the two data signal lines 10 to be repaired are both located on the left side of the display panel and the signals transmitted by the two data signal lines 10 are different, the two data signal lines 10 can be repaired separately through the two repair signal lines 20.
[0090] Optional, Fig.19 A partial structural schematic diagram of a display panel provided by an embodiment of the present invention, Fig. 20A partial structural schematic diagram of another display panel provided by an embodiment of the present invention, Fig.21 A partial structural diagram of another display panel provided by an embodiment of the present invention, referring to Figure 19-21 The data signal line 10 includes a first data line 111 and a second data line 112; the sub-pixel includes a pixel circuit 31, and the pixel circuit 31 includes an amplitude modulation sub-circuit 311 and a pulse width modulation sub-circuit 312 that are electrically connected; the amplitude modulation sub-circuit 311 is electrically connected to the first data line 111, and the pulse width modulation sub-circuit 312 is electrically connected to the second data line 112; the repair signal line 20 includes a first repair line 211, and the first data line 111 forms an overlapping area with the first repair line 211; and / or, the repair signal line 20 includes a second repair line 212, and the second data line 112 forms an overlapping area with the second repair line 212.
[0091] In the related art, the LED display panel uses a pixel circuit that combines pulse amplitude modulation (PAM) and pulse width modulation (PWM) to control the intensity and duration of the driving current to control the light-emitting state of the light-emitting element.
[0092] Specifically, the pulse width modulation subcircuit 312 is electrically connected to the amplitude modulation subcircuit 311, and the amplitude modulation subcircuit 311 is electrically connected to the light-emitting element. The pixel circuit 30 generates a driving current under the control of the amplitude modulation subcircuit 311 and the pulse width modulation subcircuit 312. The amplitude modulation subcircuit 311 can be used to control the amplitude of the driving current, and the pulse width modulation subcircuit 312 can be used to adjust the voltage pulse width applied to the light-emitting element. The pulse width modulation subcircuit 312 adjusts the actual emission period of the driving current applied to the light-emitting element by adjusting the voltage pulse width applied to the light-emitting element 20, that is, the pulse width modulation subcircuit 312 adjusts the driving current applied to the light-emitting element. At the same time, the driving current applied to the light-emitting element is maintained at a constant level to adjust the grayscale or brightness displayed by the light-emitting element, rather than adjusting the grayscale or brightness displayed by the light-emitting element by adjusting the magnitude of the driving current applied to the light-emitting element. Therefore, the amplitude modulation subcircuit 311 can provide a driving current to the light emitting element so that the light emitting element is driven with the best luminous efficiency, and adjust the grayscale or brightness displayed by the light emitting element by adjusting the light emitting duty cycle (i.e., the emission period of the light emitting element) of the light emitting element through the pulse width modulation subcircuit 312. Since it is a common technology for those skilled in the art to drive the light emitting element to emit light through the combination of the amplitude modulation subcircuit 311 and the pulse width modulation subcircuit 312, the circuit structure of the pulse width modulation subcircuit 311 and the pulse width modulation subcircuit 312 is not specifically limited in the embodiment of the present invention.
[0093] In this embodiment, a first repair line 211 that can form an overlapping area with the first data line 111 and / or a second repair line 212 that can form an overlapping area with the second data line 112 is provided, so that when a power supply abnormality occurs in the first data line 111, the first data line 111 can be repaired through the first repair line 211; when a power supply abnormality occurs in the second data line 112, the second data line 112 can be repaired through the second repair line 212, thereby improving the reliability of the electrical signal supply of the first data line 111 and / or the second data line 112, thereby improving the product qualification rate.
[0094] Specifically, for the first data lines 111 connected to the amplitude modulation subcircuit 311, the amplitude modulation subcircuit 311 provides the same driving current to the light-emitting elements of the same luminous color. Therefore, the first data lines 111 connected to the amplitude modulation subcircuit 311 corresponding to the light-emitting elements of the same luminous color can be interconnected, and one first repair line 211 can repair multiple first data lines 111 at the same time (the multiple first data lines 111 correspond to the light-emitting elements of the same color). Exemplarily, taking the sub-pixels including red sub-pixels, green sub-pixels and blue sub-pixels as an example, one first repair line 211 can be used to repair the first data lines 111 corresponding to all red sub-pixels, or to repair the first data lines 111 corresponding to all green sub-pixels, or to repair the first data lines 111 corresponding to all blue sub-pixels.
[0095] Specifically, for the second data lines 112 connected to the pulse width modulation sub-circuit 312 , different second data lines 112 transmit different data signals at the same time. Therefore, one second repair line 212 can repair one second data line 112 .
[0096] Optional, Fig. 22 A schematic diagram of the structure of another display panel provided by an embodiment of the present invention is shown in FIG. Fig. 22 As shown, the display panel 100 also includes an electrostatic protection circuit 40, which is located in the second area 02 and electrically connected to the data signal line 10; the overlapping area of the data signal line 10 and the repair signal line 20 is located on the side of the electrostatic protection circuit 40 away from the first area 01.
[0097] The electrostatic protection circuit 40 is used to perform electrostatic protection on the data signal line 10. The data signal line 10 is electrically connected to the electrostatic protection circuit 40. When there is an abnormality in the signal transmitted on the data signal line 10, the abnormal charge can be eliminated by the electrostatic protection circuit 40 to protect the data signal line 10. Since it is a common technique for those skilled in the art to protect the data signal line 10 by the electrostatic protection circuit 40, the circuit structure of the electrostatic protection circuit 40 is not specifically limited in the embodiment of the present invention.
[0098] Specifically, the overlapping area of the data signal line 10 and the repair signal line 20 is set on the side of the electrostatic protection circuit 40 away from the first area 01, so that the overlapping area of the data signal line 10 and the repair signal line 20 are close to the end of the data signal line 10, and the data signal line 10 is repaired at the end thereof. In this way, when the repair signal line 20 is enabled, the data signal transmitted by the repair signal line 20 can flow through the entire data signal line 10.
[0099] Based on the same inventive concept, an embodiment of the present invention further provides a display device, Fig.23 A schematic diagram of a display device according to an embodiment of the present invention is shown in FIG. Fig.23 As shown, the display device 200 includes at least one display panel 100 provided by any embodiment of the present invention. Therefore, the display device 200 has the technical features of the display panel 100 provided by the embodiment of the present invention, and can achieve the beneficial effects of the display panel provided by the embodiment of the present invention. The similarities can refer to the above description of the display panel provided by the embodiment of the present invention, which will not be repeated here. The display device 200 provided by the embodiment of the present invention can be any electronic product with a display function, including but not limited to the following categories: mobile phones, televisions, laptops, desktop displays, tablet computers, digital cameras, smart bracelets, smart glasses, car displays, medical equipment, industrial control equipment, touch interactive terminals, etc., and the embodiment of the present invention does not specifically limit this.
[0100] Optional, Fig.24 A schematic diagram of another display device provided by an embodiment of the present invention, referring to Figure 3 and Fig.24 , the second area 02 in the display panel 100 includes a sub-pixel 30; the display device 200 includes at least two display panels 100, and the adjacent edges of the display panels 100 are spliced together. Since the first area 01 and the second area 02 both include sub-pixels, the display panel 100 is borderless and can achieve full-screen display. By setting the adjacent edges of the display panels 100 to be spliced together, the display device 200 can have a larger size while ensuring the display effect, so as to adapt to different display requirements and improve the practicality of the display device 200. Exemplarily, the display device can be applied to the field of public information display (PID). The number of display panels 100 included in the display device 200 can be set according to actual needs, and the embodiment of the present invention is not limited to this.
