[0053] The display panel 100 may include a display area 10b and a display light-transmitting area 10a, wherein the display area 10b is located at at least one side of the display light-transmitting area 10a, for example, the display area 10b surrounds the display light-transmitting area 10a, or the display area 10b partially surrounds the display light-transmitting area 10a.

[0054] The display area 10b and the display light-transmitting area 10a are both areas including pixels for displaying images. The display light-transmitting area 10a is configured to provide a light-transmitting channel for the camera module.

[0055] Optionally, the camera module may be a camera module for facial recognition, the camera module comprising 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.

[0087] Optionally, in the repeating unit 20a of the display panel 100 in a top view, two first light-emitting devices 12r and two third light-emitting devices 12b are arranged at the four corners of the circuit island 10p, and the two first light-emitting devices 12r and the two third light-emitting devices 12b are respectively arranged to partially overlap with the circuit island 10p, and the circuit island 10p is arranged to overlap with a second light-emitting device 12g. At least one of the data line s2 and the anode power line s4 is arranged to partially overlap with another second light-emitting device 12g, and at least one of the scan line s1, the reset signal wiring s3 and the anode power line s4 is arranged to partially overlap with another second light-emitting device 12g. Such an arrangement improves the transmittance of the display light-transmitting area 10a.

[0088] In some embodiments of the present 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 of the light-emitting devices.

[0089] That is, the wire 13 is mainly composed of the transparent conductive trace 131, and is connected to the light emitting device with the via g1. Since the transparent conductive trace 131 has good light transmittance, using the transparent conductive trace 131 as the wire 13 can improve the light transmittance of the display transparent area 10a.

[0090] In some embodiments of the present 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, and at least two vias g1 are overlapped in the thickness direction of the display panel 100.

[0091] It is understandable that the via holes g1 are arranged in a stacked manner, which can reduce the arrangement area of ​​the via holes g1 and thus improve the light transmittance. Figure 3 In the embodiment, one end of the light-transmitting conductive trace 131 is connected to the first electrode 121 through a stacked structure of four via holes g1.

[0092] In some embodiments of the present application, in the display light-transmitting area 10 a , a plurality of pixel circuits 11 a are centrally arranged to form a circuit island 10 p , and a plurality of circuit islands 10 p are arranged at intervals.

[0093] In the display panel 100 viewed from a top perspective, some of the plurality of light-transmitting conductive traces 131 at least partially overlap with the circuit island 10 p .

[0094] It should be understood that the display panel 100 of the embodiment of the present application arranges the circuit island 10p corresponding to the light-emitting device connected to the display light-transmitting area 10a in the display light-transmitting area TA to shorten the signal transmission distance between the circuit island 10p and the light-emitting device, so as to improve the uniformity of the time duration of the light-emitting device receiving the signal in the display light-transmitting area 10a. Secondly, a plurality of pixel circuits 11a are arranged in a centralized manner to form a circuit island 10p, so as to save the layout area of ​​the pixel circuit 11a and improve the transmittance of the display light-transmitting area 10a. In addition, a transparent conductive trace 131 is used to at least partially overlap with the circuit island 10p to further improve the transmittance of the display light-transmitting area 10a.

[0095] In some embodiments of the present application, in a repeating unit 20a region from a top view, a light-transmitting conductive trace 131 connecting two first light-emitting devices 12r is partially overlapped with a circuit island 10p, a light-transmitting conductive trace 131 connected to a second light-emitting device 12g overlapping with the circuit island 10p is partially overlapped with the circuit island 10p, and a light-transmitting conductive trace 131 connecting two third light-emitting devices 12b is located outside the circuit island 10p.

[0096] Based on the arrangement of the light-emitting devices, the transparent conductive traces 131 are arranged in the area of ​​the circuit island 10p as much as possible to reduce the proportion of the transparent conductive traces 131 arranged in the transparent area, thereby achieving the effect of improving the transmittance of the transparent display area 10a.

[0097] In some embodiments of the present application, in the display panel 100 in a top view, the driving circuit substrate 11 further includes a first signal line 104 and a second signal line 105. In the first direction F1, the first signal line 104 extends along the first direction F1 and connects a plurality of circuit islands 10p. In the second direction, the second signal line 105 extends along the second direction F2 and connects a plurality of circuit islands 10p.

[0098] The light-transmitting conductive trace 131 connected to the second light-emitting device 12 g overlapping the circuit island 10 p extends along the second direction F2 and is disposed to partially overlap with the second signal line 105 .

[0099] Based on the arrangement of signal lines, the transparent conductive lines 131 are arranged in the signal line area as much as possible to reduce the proportion of the transparent conductive lines 131 arranged in the transparent area, thereby achieving the effect of improving the transmittance of the display transparent area 10a.

[0100] Optionally, the first signal line 104 includes a scan line s1, a reset signal line s3 and a portion of an anode power line s4. The second signal line 105 includes a data line s2 and a portion of an anode power line s4.

[0101] In some embodiments of the present application, the resistance of the light-transmitting conductive trace 131 connecting the third light-emitting device 12b is smaller than the resistance of the light-transmitting conductive trace 131 connecting the first light-emitting device 12r, and the resistance of the light-transmitting conductive trace 131 connecting the first light-emitting device 12r is smaller than the resistance of the light-transmitting conductive trace 131 connecting the second light-emitting device 12g.

[0102] It can be understood that, per unit area, the third light emitting device 12b has the lowest luminance, the second light emitting device 12g has the highest luminance, and the first light emitting device 12r has a luminance between the two. Therefore, the above design can improve the uniformity of the luminance of the three.

[0103] Optionally, the width of the light-transmitting conductive trace 131 connecting the third light-emitting device 12b is greater than the width of the light-transmitting conductive trace 131 connecting the first light-emitting device 12r, and the width of the light-transmitting conductive trace 131 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.

[0104] Among them, the width of the light-transmitting conductive trace 131 connecting the third light-emitting device 12b is the largest, the width of the light-transmitting conductive trace 131 connecting the first light-emitting device 12r is the second, and the width of the light-transmitting conductive trace 131 connecting the second light-emitting device 12g is the smallest, so as to achieve that the resistance of the light-transmitting conductive trace 131 connecting the third light-emitting device 12b is smaller than the resistance of the light-transmitting conductive trace 131 connecting the first light-emitting device 12r, and the resistance of the light-transmitting conductive trace 131 connecting the first light-emitting device 12r is smaller than the resistance of the light-transmitting conductive trace 131 connecting the second light-emitting device 12g, without increasing the mask process.

[0105] Furthermore, in some embodiments, the conductorization process of the metal oxide semiconductor layer 101 and the light-transmitting conductive trace 131 can also be utilized to control the content of doped particles doped into the light-transmitting conductive trace 131 by setting mask layers of different thicknesses, so that the number of doped particles in the light-transmitting conductive trace 131 connecting the third light-emitting device 12b is the largest, the number of doped particles in the light-transmitting conductive trace 131 connecting the first light-emitting device 12r is the second, and the number of doped particles in the light-transmitting conductive trace 131 connecting the second light-emitting device 12g is the smallest, so as to achieve that the resistance of the light-transmitting conductive trace 131 connecting the third light-emitting device 12b is smaller than the resistance of the light-transmitting conductive trace 131 connecting the first light-emitting device 12r, and the resistance of the light-transmitting conductive trace 131 connecting the first light-emitting device 12r is smaller than the resistance of the light-transmitting conductive trace 131 connecting the second light-emitting device 12g, without increasing the mask process.

[0106] Figure 4 It shows Figure 1 Another schematic structural diagram of a part of the light-transmitting area 10a is shown in FIG. Figure 5 FIG. 1 is another schematic cross-sectional structure diagram of the display panel 100 according to the embodiment of the present application.

[0107] exist Figure 4 and Figure 5 Parts different from those of the above-described embodiment will be described in order to avoid redundant description.

[0108] Please refer to Figure 4 and Figure 5 , compared to Figure 2 and Figure 3 The corresponding embodiment, Figure 4 and Figure 5 The corresponding embodiment discloses another connection structure of the wire 13, wherein 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. For details, please refer to Figure 2 and Figure 3 The description of the corresponding embodiments will not be repeated here.

[0109] exist Figure 4In some embodiments of the present application, the wire 13 includes a first wire 13a. The first wire 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 arranged 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.

[0110] 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 of the light emitting devices.

[0111] It can be understood that the display panel 100 of the embodiment of the present application uses a first wire 13a to connect two light-emitting devices, wherein the first wire 13a includes a light-transmitting conductive trace 131 and a transition trace 132. The light-transmitting conductive trace 131 arranged on the same layer as the metal oxide semiconductor layer 101 of the pixel circuit 11a is used as a part of the first wire 13a, and the transition trace 132 arranged on the same layer as the first electrode 121 is used as a part of the first wire 13a, thereby eliminating the need to additionally arrange a light-transmitting conductive layer, reducing the mask process, and achieving the effect of simplifying the structure.

[0112] In some embodiments, the light-transmitting conductive trace 131 can be formed by the same photomask process as the metal oxide semiconductor layer 101. In this case, the material of the light-transmitting conductive trace 131 is consistent with the material of the metal oxide semiconductor layer 101. In other embodiments, in the process of conductorization, the number of donor defects of the light-transmitting conductive trace 131 can be increased by differential annealing design, so that the number of donor defects of the light-transmitting conductive trace 131 is greater than the number of donor defects of the metal oxide semiconductor layer 101, thereby improving the conductivity of the light-transmitting conductive trace 131. In still other embodiments, in the process of conductorization, the doping concentration of different metal elements or the number of different metal element types can be designed so that the content of metal elements per unit volume in the light-transmitting conductive trace 131 is greater than the content of metal elements per unit volume in the metal oxide semiconductor layer 101, thereby improving the conductivity of the light-transmitting conductive trace 131; for example, the number of types of metal elements contained in the light-transmitting conductive trace 131 is greater than the number of types of metal elements contained in the metal oxide semiconductor layer 101.

[0113] In some embodiments, the transition line 132 can be formed by the same photomask process as the first electrode 121, and the material of the transition line 132 is consistent with the material of the first electrode 121, and the film layer structure is the same. In some embodiments, in the process of patterning the transition line 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 line 132, but cannot enter the first electrode 121 corresponding to the thicker mask layer, and then the transition line 132 can include metal materials other than the first electrode 121, and the resistance of the transition line 132 is smaller than the resistance of the first electrode 121, thereby improving the transmission efficiency of the signal.

[0114] In some embodiments, the transition trace 132 also fills 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 smaller than the resistance of the portion located outside the via g1, thereby improving the controllability of the current.

[0115] Optionally, the transition line 132 and the first electrode 121 are both multi-layer stacked structures. Since the transition line 132 is at least arranged in the area of ​​the circuit island 10p and the terrain of the circuit island 10p is relatively uneven, the transition line 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.

[0116] Optionally, in some embodiments of the present application, a light-transmitting conductive trace 131 is connected to the transition trace 132 through a single via g1; or, the light-transmitting conductive trace 131 is connected to the transition trace 132 through at least two vias g1, and at least two vias g1 are overlapped in the thickness direction of the display panel 100.

[0117] It can be understood that the stacking arrangement of the via holes g1 can reduce the layout area of ​​the via holes g1 , thereby improving the light transmittance of the display light-transmitting area 10 a .

[0118] Secondly, the transition line 132 is used to connect the first electrode 121, and then the transition line 132 is connected to the light-transmitting conductive line 131 through the via g1, so that the via g1 is far away from the light-emitting device electrically connected thereto, thereby saving the layout space of the light-emitting device.

[0119] Optionally, in some embodiments of the present application, in the display light-transmitting area 10a, a plurality of pixel circuits 11a are centrally arranged to form a circuit island, and a plurality of circuit islands 10p are arranged at intervals.

[0120] In the display panel 100 viewed from a top perspective, the transition trace 132 of the first conductive line 13a is overlapped with the circuit island 10p, and the light-transmitting conductive trace 131 of the first conductive line 13a is located outside the circuit island 10p.

[0121] The transition wiring 132 is overlapped with the circuit island 10p, and the light-transmitting conductive wiring 131 is arranged outside the circuit island 10p, so that the light transmittance of the light-transmitting display area 10a can be improved.

[0122] In some embodiments of the present 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.

[0123] The wire 13 includes a second wire 13b and a third wire 13c. The second wire 13b includes a transition line 132, and the third wire 13c includes a light-transmitting conductive line 131.

[0124] The two first light-emitting devices 12r are connected by a first wire 13a. The two third light-emitting devices 12b are connected by another first wire 13a. In the second direction F2, one end of the transition line 132 of the second wire 13b is connected to the second light-emitting device 12g overlapping the circuit island 10p, and the other end of the transition line 132 of the second wire 13b is connected to another second light-emitting device 12g. Among the other three second light-emitting devices 12g except the second light-emitting device 12g overlapping the circuit island 10p, two adjacent second light-emitting devices 12g are connected by a light-transmitting conductive line 131 of a third wire 13c.

[0125] In a repeating unit 20a area from a top view, 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.

[0126] It can be understood that the transition wiring 132 with or without light shielding property is arranged to overlap with the circuit island 10p as much as possible to improve the light transmittance of the display light-transmitting area 10a.

[0127] Optionally, in some embodiments of the present application, in the display panel 100 in a top view, the transition line 132 of the second wire 13 b is arranged to partially overlap with the second signal line 105 .

[0128] It can be understood that the transition wiring 132 with or without light shielding property is arranged to partially overlap with the second signal line 105 as much as possible to improve the light transmittance of the display light-transmitting area 10a.

[0129] Optionally, in some embodiments of the present application, the resistance of the transition trace 132 is smaller than the resistance of the light-transmitting conductive trace 131 .

[0130] It can be understood that, based on the multi-layer stacking structure of the transition line 132 , the transition line 132 has a lower resistance, so as to improve the conductive performance.

[0131] In some embodiments, in a repeating unit 20a, in a first conductive line 13a connecting two first light-emitting devices 12r, the length of the transition line 132 is greater than the length of the light-transmitting conductive line 131 to improve the conductive line efficiency.

[0132] Optionally, in some embodiments of the present application, the resistance of the first wire 13a connected to the third light-emitting device 12b is smaller 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 smaller than the resistance of the third wire 13c connected to the second light-emitting device 12g.

[0133] It can be understood that, per unit area, the third light emitting device 12b has the lowest luminance, the second light emitting device 12g has the highest luminance, and the first light emitting device 12r has a luminance between the two. Therefore, the above design can improve the uniformity of the luminance of the three.

[0134] Optionally, the resistance of the transition wiring 132 is smaller than the resistance of the light-transmitting conductive wiring 131. Three of the four second light-emitting devices 12g are sequentially connected by the light-transmitting conductive wiring 131, so that the resistance is relatively large, and the light-emitting efficiency of the second light-emitting device 12g is reduced to balance the uniformity of light emission.

[0135] In the first wire 13a connecting the two third light-emitting devices 12b, the length of the transition line 132 is less than the length of the light-transmitting conductive line 131, wherein the number of donor-state defects in the light-transmitting conductive line 131 can be increased through an annealing process to provide its conductive performance without reducing or even improving the transmittance.

[0136] It is understandable that in the annealing process, the light-transmitting 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.

[0137] Therefore, the conductivity and transmittance of each light-transmitting conductive trace 131 can be precisely controlled through the laser annealing process.

[0138] In some embodiments, the resistance of the light-transmitting conductive trace 131 connected to the second light-emitting device 12g is greater than the resistance of the light-transmitting conductive trace 131 electrically connected to the third light-emitting device 12b to improve the uniformity of the light-emitting brightness.

[0139] 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.

[0140] 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, and the width of the third wire 13c connecting the second light-emitting device 12g is the smallest, so as to achieve that the resistance of the first wire 13a connecting the third light-emitting device 12b is smaller 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 smaller than the resistance of the third wire 13c connecting the second light-emitting device 12g, without increasing the mask process.

[0141] Please refer to Figure 6 Accordingly, an embodiment of the present application further provides a display device 1000, comprising a display panel 100 as described in any one of the above embodiments.

[0142] It can be understood that the structure of the display panel 100 of the display device 1000 of the embodiment of the present application is similar to or the same as the structure of the display panel 100 of any of the above embodiments. Figures 1 to 5 The explanation will not be repeated here.

[0143] Optionally, the display device 1000 further includes a camera module, which is disposed on the backlight side of the display panel 100 and corresponding to the display light-transmitting area 10a.

[0144] 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 the face. The transmitter corresponds to a display light-transmitting area 10a, and the receiver corresponds to another display light-transmitting area 10a. However, it is not limited to this. For example, a display light-transmitting area 10a can be used to provide a light-transmitting channel for both the transmitter and the receiver; or the display panel 100 includes a display light-transmitting area 10a, and the camera module is a conventional camera module, such as a single camera module, a multi-camera module or an infrared camera module.

[0145] The display device 1000 of the embodiment of the present application uses a wire 13 to connect two light-emitting devices, wherein the wire 13 includes a light-transmitting conductive trace 131. The light-transmitting conductive trace 131 arranged on the same layer as the metal oxide semiconductor layer 101 of the pixel circuit 11a is used as at least a part of the wire 13, without additionally providing a light-transmitting conductive layer, thereby reducing the mask process and achieving the effect of simplifying the structure.

Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea.
