[0001] This application claims priority to Chinese patent application No. 202411667393.1, filed on November 20, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of display technology, specifically to a display panel and display device. Background Technology

[0003] In conventional under-display camera technology, in order to achieve better camera performance, most methods reduce the pixel resolution in the light-transmitting area of ​​the organic light-emitting panel, but this will reduce the display effect of the panel.

[0004] Currently, to balance display and imaging performance, panels use transparent metal leads in the light-transmitting area to connect pixel circuits and OLED devices. However, the inventors of this application have discovered that this approach requires at least three additional photomasks in the existing manufacturing process, including an ITO photomask process to form the transparent leads, a planarization layer photomask process, and an anode bottom ITO patterning photomask process, resulting in an increase in the number of manufacturing steps.

[0008] The light-emitting device layer includes a plurality of light-emitting devices, some of which are disposed in the display light-transmitting area, and a pixel circuit is correspondingly connected to at least two of the light-emitting devices;

[0009] In the display light-transmitting area, at least two light-emitting devices are electrically connected to the same pixel circuit, and the two light-emitting devices are connected by a wire;

[0057] The display panel and display device of this application embodiment are connected between two light-emitting devices by wires. The wires include light-transmitting conductive traces. The light-transmitting conductive traces are disposed on the same layer as the metal oxide semiconductor layer of the pixel circuit as at least part of the wires, without the need to set an additional light-transmitting conductive layer, thereby achieving the effect of simplifying the structure.

[0058] In Figures 1 and 2, the first direction F1 can be a direction parallel to one side of the display panel 100 in a top plan view, and for example, it can be the lateral direction of the display panel 100. The second direction F2 can be a direction parallel to the other side of the display panel 100 in a top plan view, and it can be the longitudinal direction of the display panel 100. The third direction F3 can be the thickness direction of the display panel 100. Optionally, in some embodiments, the first direction F1 and the second direction F2 may not intersect perpendicularly.

[0059] The display panel 100 may have a rectangular shape in a top plan view, but the implementation is not limited to this. In some embodiments, the display panel 100 may have a rectangular shape with vertical corners or rounded corners in a top plan view. The display panel 100 may include two short sides extending in a first direction F1 and two long sides extending in a second direction F2 in a top plan view.

[0060] The display panel 100 may include a display area 10b and a display light-transmitting area 10a, wherein the display area 10b is located on at least one side of the display light-transmitting area 10a. For example, the display area 10b may surround the display light-transmitting area 10a at its periphery, or the display area 10b may partially surround the periphery of the display light-transmitting area 10a.

[0061] Both the display area 10b and the display light-transmitting area 10a are regions containing pixels for displaying the image. The display light-transmitting area 10a is configured to provide a light transmission channel for the camera module.

[0062] Optionally, the camera module can be a camera module for face recognition, which includes a transmitter and a receiver, the transmitter being configured to emit infrared light and the receiver being configured to receive infrared light reflected from a human face.

[0063] In Figure 1, the display panel 100 includes two light-transmitting display areas 10a. One light-transmitting display area 10a is configured to provide a light transmission channel for the transmitter, and the other light-transmitting display area 10a is configured to provide a light transmission channel for the receiver. However, it is not limited to this. For example, a single light-transmitting display area 10a can be used to provide light transmission channels for both the transmitter and the receiver simultaneously; or the display panel 100 can include a single light-transmitting display area 10a configured to provide a light transmission channel for a conventional camera module, such as a single-camera module, a multi-camera module, or an infrared camera module.

[0064] Optionally, the display panel 100 includes a driving circuit substrate 11 and a light-emitting device layer 12, the light-emitting device layer 12 being disposed on the driving circuit substrate 11.

[0065] Referring to Figures 2 and 3, in the display panel 100 of one or more embodiments of this application, the driving circuit substrate 11 includes a plurality of pixel circuits 11a. The light-emitting device layer 12 includes a plurality of light-emitting devices. A portion of the plurality of light-emitting devices is disposed in the display light-transmitting area 10a. Each pixel circuit 11a is correspondingly connected to at least two of the light-emitting devices.

[0066] In at least two of the light-emitting devices that are electrically connected to the same pixel circuit 11a in the display light-transmitting area 10a, the two light-emitting devices are connected by a wire 13.

[0067] The conductor 13 includes a light-transmitting conductive trace 131. The light-transmitting conductive trace 131 is disposed on the same layer as the metal oxide semiconductor layer 101 in the pixel circuit 11a, and the light-transmitting conductive trace 131 includes at least one of the materials of the metal oxide semiconductor layer 101.

[0068] The display panel 100 of this application embodiment connects two light-emitting devices using wires 13. The wires 13 include light-transmitting conductive traces 131. The light-transmitting conductive traces 131, which are disposed on the same layer as the metal oxide semiconductor layer 101 of the pixel circuit 11a, serve as at least a part of the wires 13, without the need to additionally set a light-transmitting conductive layer, thereby reducing the photomask process and achieving the effect of simplifying the structure.

[0069] In some embodiments, the transparent conductive trace 131 can be formed using the same photomask process as the metal oxide semiconductor layer 101, in which case the material of the transparent conductive trace 131 is the same as that of the metal oxide semiconductor layer 101. In other embodiments, during the conductor-forming process, differential annealing design can be used to increase the number of donor state defects in the transparent conductive trace 131, making the number of donor state defects in the transparent conductive trace 131 greater than that in the metal oxide semiconductor layer 101, thereby improving the conductivity of the transparent conductive trace 131. In still other embodiments, during the conductor-forming process, the doping concentration of different metal elements or the number of different types of metal elements can be designed so that the content of metal elements per unit volume in the transparent conductive trace 131 is greater than that in the metal oxide semiconductor layer 101, thereby improving the conductivity of the transparent conductive trace 131; for example, the number of different types of metal elements contained in the transparent conductive trace 131 is greater than the number of different types of metal elements contained in the metal oxide semiconductor layer 101.

[0070] It is important to understand that the driving circuit substrate 11 includes a substrate 111 and a pixel circuit 11a, with the pixel circuit 11a disposed on the substrate 111. The pixel circuit 11a includes devices such as thin-film transistors and capacitors. Depending on different requirements, the pixel circuit 11a can have different driving architectures, such as 3T1C, 4T1C, 7T1C, or 13T2C, etc. Furthermore, the thin-film transistors can include a switching thin-film transistor 1k and a driving thin-film transistor 1q. The driving thin-film transistor 1q is connected to the light-emitting device, and the switching thin-film transistor 1k is connected to the driving thin-film transistor 1q.

[0071] Optionally, the structures of the driving thin-film transistor 1q and the switching thin-film transistor 1k can be the same or different. For example, both can be top-gate thin-film transistors, or one can be a top-gate type and the other a bottom-gate or dual-gate type. Optionally, the channel types of the driving thin-film transistor 1q and the switching thin-film transistor 1k can be the same or different. For example, both can be metal-oxide-semiconductor layers, or one can be a metal-oxide-semiconductor layer and the other a silicon-based semiconductor layer. Optionally, the driving thin-film transistor 1q and the switching thin-film transistor 1k can be disposed in the same layer, or at least some of the film layers can be disposed in different layers. For example, the source, drain, gate, and channel of both can be disposed in the same layer, or the source and drain can be disposed in the same layer, and the other film layers can be disposed in different layers. That is to say, the embodiments of this application do not impose specific limitations on the structure, type, and film layer position of the thin-film transistor, as long as the channel of the thin-film transistor is a metal-oxide-semiconductor layer 101.

[0072] The following explanation will use Figure 2 as an example, but it is not limited to this.

[0073] In Figure 2, the driving circuit substrate 11 further includes a light-shielding layer 112, a buffer layer 113, a silicon-based semiconductor layer 102, a first metal layer 114, a second metal layer 115, a metal oxide semiconductor layer 101, a third metal layer 116, a fourth metal layer 117, a fifth metal layer 118, and a sixth metal layer 119, which are sequentially stacked on the substrate 111. An insulating layer is disposed between any two adjacent conductive layers from the silicon-based semiconductor layer 102 to the sixth metal layer 119 in the thickness direction F3 to prevent short circuits.

[0074] The silicon-based semiconductor layer 102, the first metal layer 114, the second metal layer 115, and the fourth metal layer 117 are configured to form at least a driving thin-film transistor 1q, and the metal oxide semiconductor layer 101, the third metal layer 116, and the fourth metal layer 117 are configured to form at least a switching thin-film transistor 1k.

[0075] The fifth metal layer 118 and the sixth metal layer 119 are configured to form at least one of the following: a common electrode line, a reset signal line s3, an anode power supply line s4, a data line s2, and a layer-change trace filled with vias. The fourth metal layer 117 is configured to form at least one of the following: a data line s2, a layer-change trace filled with vias, a source, and a drain. The third metal layer 116 and the first metal layer 114 are each configured to form at least one of the following: a scan line s1, a reset signal line s3, an anode power supply line s4, a gate, a common electrode line, and a layer-change trace filled with vias.

[0076] Optionally, the anode power line s4 is mesh-shaped.

[0077] Optionally, the material of the metal oxide semiconductor layer 101 may include one of the following: oxides based on titanium, hafnium, zirconium, aluminum, tantalum, germanium, zinc, gallium, tin, or indium, as well as their composite oxides (such as indium gallium zinc oxide, indium zinc oxide, zinc tin oxide, indium gallium oxide, indium tin oxide, indium zirconium oxide, indium zirconium zinc oxide, indium zirconium tin oxide, indium zirconium gallium oxide, indium aluminum oxide, indium zinc aluminum oxide, indium tin aluminum oxide, indium aluminum gallium oxide, indium tantalum oxide, indium tantalum zinc oxide, indium tantalum tin oxide, indium tantalum gallium oxide, indium germanium oxide, indium germanium zinc oxide, indium germanium tin oxide, indium germanium gallium oxide, titanium indium zinc oxide, and hafnium indium zinc oxide).

[0078] The material of the silicon-based semiconductor layer 102 can be polycrystalline silicon, monocrystalline silicon, or amorphous silicon.

[0079] In some embodiments, the light-emitting device layer 12 includes a pixel definition layer 120, a first electrode 121, a light-emitting layer 123, and a second electrode 122. A planarization layer 103 is disposed between the first electrode 121 and the sixth metal layer 119. The pixel definition layer 120 and the first electrode 121 are disposed on the planarization layer 103. The light-emitting layer 123 is disposed on the first electrode 121, and the second electrode 122 is disposed on the light-emitting layer 123.

[0080] In this embodiment, one of the first electrode 121 and the second electrode 122 is the anode, and the other is the cathode. This embodiment is illustrated using the first electrode 121 as the anode.

[0081] The light-emitting device includes a first electrode 121, a light-emitting layer 123, and a second electrode 122 stacked together.

[0082] Optionally, the first electrode 121 can be a single film layer or a multi-film layer stacked structure. The material of the first electrode 121 can be a metal oxide, metals with various conductivity properties, alloys, and compounds and mixtures thereof. For example, indium tin oxide, indium zinc oxide, gold, silver, aluminum, aluminum-silicon, aluminum-titanium, metal nitrides, indium tin oxide / silver / indium tin oxide, etc., can be used.

[0083] The material of the second electrode 122 may include metal oxides, such as indium tin oxide, indium zinc oxide, etc.

[0084] Referring to Figure 3, the plurality of light-emitting devices include a first light-emitting device 12r, a second light-emitting device 12g, and a third light-emitting device 12b. The first light-emitting device 12r is configured to emit red light. The second light-emitting device 12g is configured to emit green light. The third light-emitting device 12b is configured to emit blue light. In the first direction F1, the first light-emitting device 12r and the third light-emitting device 12b are arranged alternately, and the plurality of second light-emitting devices 12g are arranged between adjacent first light-emitting devices 12r and third light-emitting devices 12b.

[0085] On the second direction F2, which intersects with the first direction F1, the first light-emitting device 12r and the third light-emitting device 12b are arranged alternately, and a plurality of second light-emitting devices 12g are arranged, with the second light-emitting devices 12g positioned between adjacent first light-emitting devices 12r and third light-emitting devices 12b.

[0086] In other words, the first light-emitting device 12r and the third light-emitting device 12b are arranged alternately along the first direction F1 to form a mixed-color sub-pixel row. Multiple second light-emitting devices 12g are arranged along the first direction F1 to form a solid-color sub-pixel row. The first light-emitting device 12r and the third light-emitting device 12b are arranged alternately along the second direction F2 to form a mixed-color sub-pixel column. Multiple second light-emitting devices 12g are arranged along the second direction F2 to form a solid-color sub-pixel column. In the first direction F1, the mixed-color sub-pixel column and the solid-color sub-pixel column are arranged alternately. In the second direction F2, the mixed-color sub-pixel row and the solid-color sub-pixel row are arranged alternately.

[0087] It should be noted that the arrangement of the light-emitting devices in Figure 3 is only one embodiment of this application. In some embodiments, other arrangements may also be used, and this application does not impose any restrictions.

[0088] In one or more embodiments of this application, at least two first light-emitting devices 12r, at least two second light-emitting devices 12g, and at least two third light-emitting devices 12b form a repeating unit 20a.

[0089] One pixel circuit 11a in circuit island 10p is connected to the first light-emitting device 12r in repeating unit 20a, another pixel circuit 11a in circuit island 10p is connected to the second light-emitting device 12g in repeating unit 20a, and yet another pixel circuit 11a in circuit island 10p is connected to the third light-emitting device 12b in repeating unit 20a.

[0090] In the display panel 100 viewed from above, at least one of the first light-emitting device 12r, the second light-emitting device 12g, and the third light-emitting device 12b at least partially overlaps with the circuit island 10p.

[0091] Understandably, in the display light-transmitting area 10a, multiple repeating units 20a are arranged along the first direction F1 and the second direction F2. Circuit islands 10p are also arranged along the first direction F1 and the second direction F2. Each circuit island 10p drives one repeating unit 20a, and each circuit island 10p is positioned within the area of ​​one repeating unit 20a, allowing the circuit islands 10p to be evenly arranged. This improves the light transmission uniformity of the display light-transmitting area 10a while also enhancing the uniformity of signal transmission.

[0092] Secondly, based on the light-shielding properties of the light-emitting devices, at least one of the first light-emitting device 12r, the second light-emitting device 12g, and the third light-emitting device 12b overlaps at least partially with the circuit island 10p, which can improve the light transmittance of the display light-transmitting area 10a.

[0093] Based on Figure 3, the repeating unit 20a includes two first light-emitting devices 12r, two third light-emitting devices 12b, and four second light-emitting devices 12g. In each repeating unit 20a, one pixel circuit 11a in the circuit island 10p drives two first light-emitting devices 12r, another pixel circuit 11a in the circuit island 10p drives four second light-emitting devices 12g, and yet another pixel circuit 11a in the circuit island 10p drives two third light-emitting devices 12b.

[0094] Optionally, in the repeating unit 20a of the display panel 100 from a top-view perspective, two first light-emitting devices 12r and two third light-emitting devices 12b are arranged at the four corners of the circuit island 10p. The two first light-emitting devices 12r and the two third light-emitting devices 12b are respectively partially overlapped with the circuit island 10p, and the circuit island 10p overlaps with a second light-emitting device 12g. At least one of the data line s2 and the anode power line s4 partially overlaps with another second light-emitting device 12g, and at least one of the scan line s1, the reset signal line s3, and the anode power line s4 partially overlaps with yet another second light-emitting device 12g. This arrangement improves the light transmittance of the display light-transmitting area 10a.

[0095] In some embodiments of this application, one end of the light-transmitting conductive trace 131 is connected to one of the light-emitting devices, and the other end of the light-transmitting conductive trace 131 is connected to another light-emitting device.

[0096] In other words, the conductor 13 is mainly composed of the light-transmitting conductive trace 131, and is connected to the light-emitting device with via g1. Since the light-transmitting conductive trace 131 has good light transmittance, using the light-transmitting conductive trace 131 as the conductor 13 can improve the light transmittance of the light-transmitting area 10a of the display.

[0097] In some embodiments of this application, the light-transmitting conductive trace 131 is connected to the light-emitting device through a single via g1; or, the light-transmitting conductive trace 131 is connected to the light-emitting device through at least two vias g1, with at least two vias g1 overlapping in the thickness direction of the display panel 100.

[0098] Understandably, the vias g1 are arranged in a stacked manner, which can reduce the arrangement area of ​​the vias g1 and thus improve the light transmittance. For example, in Figure 3, one end of the light-transmitting conductive trace 131 is connected to the first electrode 121 through the stacked structure of four vias g1.

[0099] In some embodiments of this application, in the light-transmitting area 10a, multiple pixel circuits 11a are arranged in a concentrated manner to form a circuit island 10p, and the multiple circuit islands 10p are arranged at intervals.

[0100] In the display panel 100 viewed from above, some of the light-transmitting conductive traces 131 overlap with the circuit island 10p at least partially.

[0101] It should be understood that, in this embodiment of the application, the display panel 100 shortens the signal transmission distance between the circuit island 10p and the light-emitting device by setting the circuit island 10p corresponding to the light-emitting device connected to the light-transmitting area 10a in the light-transmitting area TA, thereby improving the uniformity of signal reception duration of the light-emitting device in the light-transmitting area 10a. Secondly, multiple pixel circuits 11a are arranged in a concentrated manner to form a circuit island 10p, thereby saving the layout area of ​​the pixel circuits 11a and improving the light transmittance of the light-transmitting area 10a. Furthermore, the use of a light-transmitting conductive trace 131 that at least partially overlaps with the circuit island 10p further improves the light transmittance of the light-transmitting area 10a.

[0102] In some embodiments of this application, in a repeating unit 20a region from a top-down view, the light-transmitting conductive traces 131 connecting the two first light-emitting devices 12r partially overlap with the circuit island 10p, the light-transmitting conductive traces 131 connecting the second light-emitting device 12g overlapping with the circuit island 10p partially overlap with the circuit island 10p, and the light-transmitting conductive traces 131 connecting the two third light-emitting devices 12b are located outside the circuit island 10p.

[0103] In this way, based on the arrangement of the light-emitting devices, the light-transmitting conductive traces 131 are placed in the area of ​​the circuit island 10p as much as possible, so as to reduce the proportion of the light-transmitting conductive traces 131 in the light-transmitting area and achieve the effect of improving the light transmittance of the display light-transmitting area 10a.

[0104] In some embodiments of this application, in the display panel 100 viewed from above, the driving circuit board 11 further includes a first signal line 104 and a second signal line 105. In a first direction F1, the first signal line 104 extends along the first direction F1 and connects to a plurality of circuit islands 10p. In a second direction, the second signal line 105 extends along the second direction F2 and connects to a plurality of circuit islands 10p.

[0105] The light-transmitting conductive trace 131, which is connected to the second light-emitting device 12g that overlaps with the circuit island 10p, extends along the second direction F2 and partially overlaps with the second signal line 105.

[0106] In this process, based on the arrangement of signal traces, the light-transmitting and conductive traces 131 are placed in the area of ​​the signal traces as much as possible, so as to reduce the proportion of the light-transmitting and conductive traces 131 in the light-transmitting area and thus improve the light transmittance of the light-transmitting area 10a.

[0107] Optionally, the first signal line 104 includes portions of the scan line s1, the reset signal line s3, and the anode power supply line s4. The second signal line 105 includes portions of the data line s2 and the anode power supply line s4.

[0108] In some embodiments of this application, the resistance of the light-transmitting conductive trace 131 connected to the third light-emitting device 12b is less than the resistance of the light-transmitting conductive trace 131 connected to the first light-emitting device 12r, and the resistance of the light-transmitting conductive trace 131 connected to the first light-emitting device 12r is less than the resistance of the light-transmitting conductive trace 131 connected to the second light-emitting device 12g.

[0109] It is understandable that, per unit area, the third light-emitting device 12b has the lowest luminous intensity, the second light-emitting device 12g has the highest luminous intensity, and the first light-emitting device 12r has a luminous intensity in between. Therefore, the above design can improve the uniformity of the luminous intensity of the three devices.

[0110] Optionally, the width of the transparent conductive trace 131 connecting the third light-emitting device 12b is greater than the width of the transparent conductive trace 131 connecting the first light-emitting device 12r, and the width of the transparent conductive trace 131 connecting the first light-emitting device 12r is greater than the width of the transparent conductive trace 131 connecting the second light-emitting device 12g.

[0111] Among them, the width of the transparent conductive trace 131 connecting the third light-emitting device 12b is the largest, the width of the transparent conductive trace 131 connecting the first light-emitting device 12r is the second largest, and the width of the transparent conductive trace 131 connecting the second light-emitting device 12g is the smallest. This is to ensure that the resistance of the transparent conductive trace 131 connecting the third light-emitting device 12b is less than the resistance of the transparent conductive trace 131 connecting the first light-emitting device 12r, and the resistance of the transparent conductive trace 131 connecting the first light-emitting device 12r is less than the resistance of the transparent conductive trace 131 connecting the second light-emitting device 12g, without increasing the photomask process.

[0112] Furthermore, in some embodiments, the conductor-forming process of the metal oxide semiconductor layer 101 and the transparent conductive lines 131 can be utilized. By setting mask layers of different thicknesses, the content of doped particles incorporated into the transparent conductive lines 131 can be controlled, so that the number of doped particles in the transparent conductive lines 131 connected to the third light-emitting device 12b is the largest, the number of doped particles in the transparent conductive lines 131 connected to the first light-emitting device 12r is the second largest, and the number of doped particles in the transparent conductive lines 131 connected to the second light-emitting device 12g is the smallest. This achieves that the resistance of the transparent conductive lines 131 connected to the third light-emitting device 12b is less than the resistance of the transparent conductive lines 131 connected to the first light-emitting device 12r, and the resistance of the transparent conductive lines 131 connected to the first light-emitting device 12r is less than the resistance of the transparent conductive lines 131 connected to the second light-emitting device 12g, without increasing the photomask process.

[0113] Figure 4 shows another structural schematic diagram of a portion of the light-transmitting area 10a shown in Figure 1. Figure 5 shows another cross-sectional structural schematic diagram of the display panel 100 according to an embodiment of this application.

[0114] In Figures 4 and 5, the parts that differ from the above embodiments will be described to avoid redundancy.

[0115] Please refer to Figures 4 and 5. Compared with the embodiments corresponding to Figures 2 and 3, the embodiments corresponding to Figures 4 and 5 disclose another connection structure of the conductor 13. The film layer structure of the display panel 100, the arrangement of the light-emitting devices, the circuit island 10p and the driving method of the repeating unit 20a are the same. Please refer to the description of the embodiments corresponding to Figures 2 and 3 for details, which will not be repeated here.

[0116] In Figure 4, in some embodiments of this application, the conductor 13 includes a first conductor 13a. The first conductor 13a includes a light-transmitting conductive trace 131 and a transition trace 132 connected to the light-transmitting conductive trace 131. The transition trace 132 is disposed in the same layer as the first electrode 121 of the light-emitting device. The transition trace 132 is connected to the first electrode 121, and the transition trace 132 includes at least one of the materials of the first electrode.

[0117] One end of the first wire 13a is connected to one of the light-emitting devices, and the other end of the first wire 13a is connected to another light-emitting device.

[0118] It is understood that the display panel 100 in this embodiment of the application uses a first conductive line 13a to connect the two light-emitting devices. The first conductive line 13a includes a light-transmitting conductive line 131 and a transition line 132. The light-transmitting conductive line 131, which is disposed on the same layer as the metal oxide semiconductor layer 101 of the pixel circuit 11a, is used as part of the first conductive line 13a. The transition line 132, which is disposed on the same layer as the first electrode 121, is used as part of the first conductive line 13a. Therefore, it is not necessary to set an additional light-transmitting conductive layer, reduce the photomask process, and achieve the effect of simplifying the structure.

[0119] In some embodiments, the transparent conductive trace 131 can be formed using the same photomask process as the metal oxide semiconductor layer 101, in which case the material of the transparent conductive trace 131 is the same as that of the metal oxide semiconductor layer 101. In other embodiments, during the conductor-forming process, differential annealing design can be used to increase the number of donor state defects in the transparent conductive trace 131, making the number of donor state defects in the transparent conductive trace 131 greater than that in the metal oxide semiconductor layer 101, thereby improving the conductivity of the transparent conductive trace 131. In still other embodiments, during the conductor-forming process, the doping concentration of different metal elements or the number of different types of metal elements can be designed so that the content of metal elements per unit volume in the transparent conductive trace 131 is greater than that in the metal oxide semiconductor layer 101, thereby improving the conductivity of the transparent conductive trace 131; for example, the number of different types of metal elements contained in the transparent conductive trace 131 is greater than the number of different types of metal elements contained in the metal oxide semiconductor layer 101.

[0120] In some embodiments, the transition trace 132 can be formed using the same photomask process as the first electrode 121. In this case, the material of the transition trace 132 is the same as that of the first electrode 121, and the film structure is the same. In some embodiments, in the fabrication processes of the patterned transition trace 132 and the first electrode 121, mask layers of different thicknesses can be designed so that doped particles can pass through the thinner mask layer and enter the transition trace 132, but cannot enter the first electrode 121, which has a thicker mask layer. As a result, the transition trace 132 can contain metal materials other than the first electrode 121, and the resistance of the transition trace 132 is less than that of the first electrode 121, thereby improving signal transmission efficiency.

[0121] In some embodiments, the transition trace 132 may also fill the via g1. Since the via g1 is deeper, the doped particles cannot continue to penetrate into the via g1, so that the resistance of the portion of the transition trace 132 located inside the via g1 is greater than the resistance of the portion located outside the via g1, thereby improving the controllability of the current.

[0122] Optionally, both the transition trace 132 and the first electrode 121 are multi-layer stacked structures. Since the transition trace 132 is located at least in the area of ​​the circuit island 10p, and the terrain of the circuit island 10p is relatively uneven, the transition trace 132 with a multi-layer stacked structure is thicker and has a metal layer, which can reduce the risk of breakage compared to metal oxide materials.

[0123] Optionally, in some embodiments of this application, a transparent conductive trace 131 is connected to a transition trace 132 through a single via g1; or, the transparent conductive trace 131 is connected to the transition trace 132 through at least two vias g1, with at least two vias g1 overlapping in the thickness direction of the display panel 100.

[0124] Understandably, the stacking arrangement of vias g1 can reduce the layout area of ​​vias g1, thereby increasing the light transmittance of the display light-transmitting area 10a.

[0125] Secondly, a transition trace 132 is used to connect the first electrode 121. Then, the transition trace 132 is connected to the light-transmitting conductive trace 131 through the via g1, so that the via g1 is far away from the light-emitting device that is electrically connected to it, saving the layout space of the light-emitting device.

[0126] Optionally, in some embodiments of this application, in the display light-transmitting area 10a, multiple pixel circuits 11a are arranged in a concentrated manner to form a circuit island, and multiple circuit islands 10p are arranged at intervals.

[0127] In the display panel 100 viewed from above, the transition trace 132 of the first conductor 13a overlaps with the circuit island 10p, and the light-transmitting conductive trace 131 of the first conductor 13a is located outside the circuit island 10p.

[0128] By overlapping the transition trace 132 with the circuit island 10p and placing the light-transmitting conductive trace 131 outside the circuit island 10p, the light transmittance of the display light-transmitting area 10a can be improved.

[0129] In some embodiments of this application, the repeating unit 20a includes two first light-emitting devices 12r, two third light-emitting devices 12b, and four second light-emitting devices 12g.

[0130] Conductor 13 includes a second conductor 13b and a third conductor 13c. The second conductor 13b includes a transition trace 132, and the third conductor 13c includes a light-transmitting conductive trace 131.

[0131] Two first light-emitting devices 12r are connected by a first wire 13a. Two third light-emitting devices 12b are connected by another first wire 13a. In the second direction F2, one end of the transition trace 132 of the second wire 13b is connected to the second light-emitting device 12g that overlaps with the circuit island 10p, and the other end of the transition trace 132 of the second wire 13b is connected to another second light-emitting device 12g. Among the three second light-emitting devices 12g other than the second light-emitting device 12g that overlaps with the circuit island 10p, two adjacent second light-emitting devices 12g are connected by a light-transmitting conductive trace 131 of a third wire 13c.

[0132] In a repeating unit 20a region from a top-down perspective, the transition trace 132 of the first conductor 13a overlaps with the circuit island 10p, the light-transmitting conductive trace 131 of the first conductor 13a is located outside the circuit island 10p, the second conductor 13b partially overlaps with the circuit island 10p, and the third conductor 13c is located outside the circuit island 10p.

[0133] It is understandable that the transition traces 132, which may or may not have light-shielding properties, are arranged to overlap with the circuit island 10p as much as possible in order to improve the light transmittance of the display light-transmitting area 10a.

[0134] Optionally, in some embodiments of this application, in the display panel 100 viewed from above, the transition trace 132 of the second conductor 13b partially overlaps with the second signal line 105.

[0135] It is understandable that the transition trace 132, which may or may not have light-shielding properties, is arranged to overlap with the second signal line 105 as much as possible in order to improve the light transmittance of the display light-transmitting area 10a.

[0136] Optionally, in some embodiments of this application, the resistance of the transition trace 132 is less than the resistance of the transparent conductive trace 131.

[0137] Understandably, the transition trace 132 adopts a multi-layer stacked structure, which makes the transition trace 132 have lower resistance, thereby improving conductivity.

[0138] In some embodiments, in a repeating unit 20a, in the first wire 13a connecting the two first light-emitting devices 12r, the length of the transition trace 132 is greater than the length of the light-transmitting conductive trace 131, so as to improve the efficiency of the wire.

[0139] Optionally, in some embodiments of this application, the resistance of the first wire 13a connected to the third light-emitting device 12b is less than the resistance of the first wire 13a connected to the first light-emitting device 12r, and the resistance of the first wire 13a connected to the first light-emitting device 12r is less than the resistance of the third wire 13c connected to the second light-emitting device 12g.

[0140] It is understandable that, per unit area, the third light-emitting device 12b has the lowest luminous intensity, the second light-emitting device 12g has the highest luminous intensity, and the first light-emitting device 12r has a luminous intensity in between. Therefore, the above design can improve the uniformity of the luminous intensity of the three devices.

[0141] Optionally, the resistance of the transition trace 132 is less than the resistance of the transparent conductive trace 131. However, three of the four second light-emitting devices 12g are connected sequentially using the transparent conductive trace 131, resulting in a higher resistance and reducing the luminous efficiency of the second light-emitting devices 12g to balance the uniformity of light emission.

[0142] In the first wire 13a connecting the two third light-emitting devices 12b, the length of the transition trace 132 is less than the length of the light-transmitting conductive trace 131. The number of donor state defects in the light-transmitting conductive trace 131 can be increased by annealing process, so as to improve its conductivity without reducing or even increasing the light transmittance.

[0143] Understandably, in the annealing process, the transparent conductive trace 131 of the metal oxide material can be annealed by controlling the annealing temperature and time, so that the grains inside can grow better and the grain boundary density can be increased, thereby improving its light transmittance.

[0144] Therefore, the conductivity and transmittance of each transparent and conductive trace 131 can be precisely controlled through laser annealing.

[0145] In some embodiments, the resistance of the light-transmitting conductive trace 131 connecting the second light-emitting device 12g is greater than the resistance of the light-transmitting conductive trace 131 electrically connecting the third light-emitting device 12b, so as to improve the uniformity of light emission brightness.

[0146] Optionally, the width of the first wire 13a connecting the third light-emitting device 12b is greater than the width of the first wire 13a connecting the first light-emitting device 12r, and the width of the first wire 13a connecting the first light-emitting device 12r is greater than the width of the light-transmitting conductive trace 131 connecting the second light-emitting device 12g.

[0147] Among them, the width of the first wire 13a connecting the third light-emitting device 12b is the largest, the width of the first wire 13a connecting the first light-emitting device 12r is the second largest, and the width of the third wire 13c connecting the second light-emitting device 12g is the smallest. This is to ensure that the resistance of the first wire 13a connecting the third light-emitting device 12b is less than the resistance of the first wire 13a connecting the first light-emitting device 12r, and the resistance of the first wire 13a connecting the first light-emitting device 12r is less than the resistance of the third wire 13c connecting the second light-emitting device 12g, without increasing the photomask process.

[0149] It is understood that the structure of the display panel 100 of the display device 1000 in this application embodiment is similar to or the same as the structure of the display panel 100 of any of the above embodiments. For details, please refer to the descriptions in Figures 1 to 5, which will not be repeated here.

[0150] Optionally, the display device 1000 also includes a camera module, which is disposed on the backlight side of the display panel 100 and is disposed corresponding to the display light-transmitting area 10a.

[0151] The camera module includes a transmitter and a receiver. The transmitter is configured to emit infrared light, and the receiver is configured to receive infrared light reflected from a human face. The transmitter corresponds to one display light-transmitting area 10a, and the receiver corresponds to another display light-transmitting area 10a. However, this is not a limitation. For example, a single display light-transmitting area 10a can be used to provide a light transmission channel for both the transmitter and the receiver; or the display panel 100 can include one display light-transmitting area 10a, and the camera module can be a conventional camera module, such as a single-camera module, a multi-camera module, or an infrared camera module.

[0152] The display device 1000 of this application embodiment connects two light-emitting devices using a wire 13. The wire 13 includes a light-transmitting conductive trace 131. The light-transmitting conductive trace 131, which is disposed on the same layer as the metal oxide semiconductor layer 101 of the pixel circuit 11a, serves as at least a part of the wire 13, without the need to additionally provide a light-transmitting conductive layer, thereby reducing the photomask process and achieving the effect of simplifying the structure.

[0153] The above provides a detailed description of a display panel and display device provided in the embodiments of this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
