Detailed implementation manners

[0073] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure content of the present application more thorough and comprehensive.

[0074] It should be understood that although terms such as "first" and "second" may be used herein to describe various elements, they do not denote any order, quantity, or importance, but are merely used to distinguish different components. These terms are only used to distinguish one element from another. For example, without departing from the scope of the present application, the first element may be referred to as the second element, and similarly, the second element may be referred to as the first element. Words such as "including" or "comprising" mean that the element or item appearing before this word encompasses the elements or items listed after this word and their equivalents, without excluding other elements or items.

[0075] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the description of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0076] Organic Light Emitting Diode (OLED) display technology is regarded as the most potential new flat panel display technology for the next generation. Compared with liquid crystal display technology, OLED display technology has the advantages of low power consumption, low cost, self-luminescence, wide viewing angle, and fast response speed.

[0077] In the process of implementing this application, the inventors found the following problems in the related art: The display panel may include a substrate and a plurality of light-emitting devices disposed on the substrate. Each light-emitting device includes an anode, a light-emitting layer, and a cathode sequentially disposed in a direction away from the substrate, and the cathodes of the respective light-emitting devices are common cathodes.

[0078] However, the driving voltages of the light-emitting devices of different colors in the display panel are different, so the cathode potentials required by the light-emitting devices are also different. However, the cathode of the display panel is a common cathode, resulting in the inability to separate the cathode potentials of the respective light-emitting devices. Providing the same cathode potential to the light-emitting devices of different colors will cause the cathode potential of some color light-emitting devices to be too high, thereby increasing the additional power consumption of the display panel and resulting in a relatively high power consumption of the display panel. In addition, in an OLED display panel integrated with an organic photodiode (OPD for short), the cathode potential required by the OPD is different from that of the light-emitting device. Sharing the cathode potential between the OPD and the light-emitting device will cause the cathode potential of one of them to be relatively high, resulting in a relatively high power consumption of the display panel. Secondly, sharing the cathode potential between the OPD and the light-emitting device will also affect their respective performances.

[0079] In view of the above at least one problem, an embodiment of the present application provides a display panel and a display device, which can improve the electrical performance of the display panel.

[0080] The following will be combined with Figures 1-6 to describe the display panel 100 and the display device provided by the embodiment of the present application.

[0081] An embodiment of the present application provides a display device, which may include a display panel 100. The display device may be an electronic paper, a mobile phone, a tablet computer, a television, a monitor, a laptop computer, a digital photo frame, a smart bracelet, a smart watch, a super personal computer, a navigator, a wireless device, a personal digital assistant (PDA), a handheld or portable computer, a GPS receiver / navigator, a camera, an MP4 video player, a video camera, a game console, a clock, a calculator, a TV monitor, a computer monitor, an automotive display (such as an odometer display, etc.), a cockpit controller and / or display, a display of a camera view (such as a display of a rear view camera in a vehicle), an electronic billboard or sign, a projector, or other mobile or fixed terminals.

[0082] Exemplarily, the display panel 100 may be an organic light-emitting diode (OLED) display panel, a micro organic light-emitting diode (Micro OLED) display panel, or a quantum dot light emitting diodes (QLED) display panel. In the embodiment of the present application, the OLED display panel 100 is taken as an example for description.

[0083] The following description is made on the display panel 100 provided by the embodiment of the present application.

[0084] See Figure 1 and Figure 2, the display panel 100 may have a first direction A, a second direction B, and a third direction C, and the first direction A, the second direction B, and the third direction C are all different. The first direction A and the second direction B may be any two different directions parallel to the display panel 100, and the third direction C may be any direction intersecting the plane parallel to the display panel 100. For example, the first direction A, the second direction B, and the third direction C may be perpendicular to each other in pairs. Exemplarily, the first direction A may be the width direction of the display panel 100, the second direction B may be the length direction of the display panel 100, and the third direction C may be the thickness direction of the display panel 100. The length, width, thickness, etc. in the embodiments of the present application are only for convenience of description and do not mean any limitation on the size. For example, the width may be greater than, equal to, or less than the length. The direction of the display panel 100 may be consistent with the direction of the film layer such as the substrate 101.

[0085] See Figure 1 , an embodiment of the present application provides a display panel 100, and the display panel 100 may include a substrate 101. The substrate 101 may provide support for the remaining film layers to be subsequently provided.

[0086] In some embodiments, see Figure 2 , the display panel 100 may include a plurality of repeating unit groups 103, and the plurality of repeating unit groups 103 are all disposed on one side of the substrate 101, and the plurality of repeating unit groups 103 may be arranged along the first direction A. Each repeating unit group 103 may include a plurality of optical devices 130 arranged along the second direction B.

[0087] Exemplarily, in the same repeating unit group 103, the plurality of optical devices 130 may include a first optical device 131 and a second optical device 132.

[0088] Exemplarily, in the same repeating unit group 103, there is a spacing region between two adjacent optical devices 130 along the second direction B. In two adjacent repeating unit groups 103, the optical devices 130 in one repeating unit group 103 are disposed opposite to the spacing region of the other repeating unit group 103 along the first direction A. That is, in two adjacent repeating unit groups 103, the optical devices 130 in one repeating unit group 103 are offset from the optical devices 130 of the other repeating unit group 103 along the first direction A. Alternatively, in two adjacent repeating unit groups 103, the optical devices 130 in one repeating unit group 103 are disposed opposite to the optical devices 130 of the other repeating unit group 103 along the first direction A.

[0089] Exemplarily, in the same repeating unit group 103, multiple optical devices 130 may be arranged in a row along the second direction B, or multiple optical devices 130 may be arranged in a column along the first direction A. In the embodiments of the present application, it is taken as an example that in the same repeating unit group 103, multiple optical devices 130 are arranged in a row along the second direction B for illustration.

[0090] Exemplarily, referring to Figure 1 , the optical device 130 may include a light-emitting device 135 or a photosensitive device 136.

[0091] Exemplarily, any one light-emitting device 135 may be a red light-emitting device, a green light-emitting device, or a blue light-emitting device. In some other examples, any one light-emitting device 135 may be a white light-emitting device.

[0092] Exemplarily, the photosensitive device 136 may include a photodiode, for example, an organic photodiode.

[0093] Exemplarily, the photosensitive device 136 is correspondingly arranged with a photosensitive circuit, and the photosensitive device 136 is electrically connected to the corresponding photosensitive circuit. The photosensitive circuit is connected to the fingerprint recognition chip. When a finger touches the display area, the light-emitting device 135 emits light, and after the light is reflected by the finger and received by the photosensitive device 136, the photosensitive device 136 generates an electrical signal according to the received light and transmits the electrical signal to the photosensitive circuit, and the photosensitive circuit then transmits the electrical signal to the fingerprint recognition chip, and the fingerprint recognition chip performs fingerprint recognition according to the electrical signals sent by each photosensitive circuit. By performing fingerprint recognition through the photosensitive device 136, it is possible not to set up an in-screen fingerprint recognition device and to achieve full-screen fingerprint recognition.

[0094] Referring to Figure 1 and Figure 2 , the display panel 100 may include a plurality of first power supply lines 110 and a plurality of second power supply lines 120. The plurality of first power supply lines 110 and the plurality of second power supply lines 120 are both arranged on one side of the substrate 101. The first power supply lines 110 and the second power supply lines 120 are alternately arranged along the first direction A. The first power supply lines 110 and the second power supply lines 120 may be insulated from each other, and the first power supply lines 110 and the second power supply lines 120 may be independently powered. The first power supply line 110 is electrically connected to the first optical device 131, and the second power supply line 120 is electrically connected to the second optical device 132. In this way, the first optical device 131 and the second optical device 132 can be separately powered to respectively meet the different power supply requirements of the first optical device 131 and the second optical device 132, and it is possible to avoid the first optical device 131 and the second optical device 132 sharing the same power supply line and affecting their respective performances, thereby improving the electrical performance of the display panel.

[0095] Exemplarily, the first power supply line 110 and the second power supply line 120 have different potentials. The first power supply line 110 provides a first potential, and the second power supply line 120 provides a second potential. In this way, the requirements for different potentials of the first optical device 131 and the second optical device 132 can be met, and the potential of the first optical device 131 or the second optical device 132 can be prevented from being too high, thereby reducing the power consumption of the display panel and avoiding the influence on their respective electrical performances due to the first optical device 131 and the second optical device 132 sharing the same potential.

[0096] Exemplarily, the first power supply line 110 and the second power supply line 120 extend along the second direction B.

[0097] Exemplarily, the orthographic projection of a first power supply line 110 on the substrate 101 is a first orthographic projection, the orthographic projection of a second power supply line 120 on the substrate 101 is a second orthographic projection, and the orthographic projection of a repeating unit group 103 on the substrate 101 is a third orthographic projection. The third orthographic projection is at least partially located between adjacent first and second orthographic projections. Among the adjacent first and second orthographic projections and the third orthographic projection located between the first and second orthographic projections, the first power supply line 110 corresponding to the first orthographic projection is electrically connected to the first optical device 131 of the repeating unit group 103 corresponding to the third orthographic projection. The first power supply line 110 supplies a first potential to the first optical device 131 of the repeating unit group 103. The second power supply line 120 corresponding to the second orthographic projection is electrically connected to the second optical device 132 of the repeating unit group 103 corresponding to the third orthographic projection. The second power supply line 120 supplies a second potential to the second optical device 132 of the repeating unit group 103. Thus, different potentials can be provided to the first optical device 131 and the second optical device 132 of the repeating unit group 103 through the first power supply line 110 and the second power supply line 120, so that the potentials provided to the first optical device 131 and the second optical device 132 are separated to meet the potential requirements of the first optical device 131 and the second optical device 132 respectively, and the potential of the first optical device 131 or the second optical device 132 is prevented from being too high, thereby reducing the power consumption of the display panel 100 and also avoiding the influence on their respective performances due to the first optical device 131 and the second optical device 132 sharing the same potential.

[0098] Exemplarily, among two adjacent third orthographic projections and the first orthographic projection located between the two adjacent third orthographic projections, the first power supply line 110 corresponding to the first orthographic projection is electrically connected to the first optical devices 131 of the repeating unit groups 103 corresponding to the two third orthographic projections, that is, the first power supply line 110 can supply a first potential to the first optical devices 131 of two adjacent repeating unit groups 103.

[0099] Exemplarily, in two adjacent third orthographic projections and the second orthographic projection located between the two adjacent third orthographic projections, the second power line 120 corresponding to the second orthographic projection is electrically connected to the second optical devices 132 of the repeating unit groups 103 corresponding to the two third orthographic projections. That is, the second power line 120 can supply the second potential to the second optical devices 132 of the two adjacent repeating unit groups 103.

[0100] Exemplarily, the potentials of the plurality of first power lines 110 are the same, and the potentials of the plurality of second power lines 120 are the same. By providing the plurality of first power lines 110 and the plurality of second power lines 120, and arranging the first power lines 110 and the second power lines 120 alternately, the plurality of first power lines 110 can supply the same potential (i.e., the first potential) to all the first optical devices 131 of the display panel 100, and the plurality of second power lines 120 can supply the same potential (i.e., the second potential) to all the second optical devices 132 of the display panel 100.

[0101] Exemplarily, the first power line 110 and the second power line 120 are arranged on the same layer and made of the same material, which is beneficial to simplifying the manufacturing process of the first power line 110 and the second power line 120 and reducing the manufacturing cost.

[0102] It should be noted that "on the same layer and made of the same material" in the embodiments of the present application means that a base film layer is formed of the same material, and after patterning and / or other processing techniques are performed on the base film layer, different parts of the base film layer are respectively formed into multiple structural film layers. The processing techniques for forming the different structural film layers may be the same or different, and the formed different structural film layers may have the same or different thicknesses, and may also be on the same horizontal plane or different horizontal planes.

[0103] The following describes the first optical device 131 and the second optical device 132 provided in the embodiments of the present application.

[0104] In some embodiments, at least one of the first optical device 131 and the second optical device 132 may be a light-emitting device 135. For example, both the first optical device 131 and the second optical device 132 may be light-emitting devices 135. Alternatively, one of the first optical device 131 and the second optical device 132 may be a light-emitting device 135, and the other may be a photosensitive device 136.

[0105] In an embodiment where both the first optical device 131 and the second optical device 132 are light-emitting devices 135, the first optical device 131 and the second optical device 132 have different light-emitting colors. Thus, different potentials can be provided to the light-emitting devices 135 with different light-emitting colors on the display panel 100 through the first power supply line 110 and the second power supply line 120 respectively, so that the potentials of the light-emitting devices 135 with different light-emitting colors are separated, to respectively meet the requirements of the light-emitting devices 135 with different light-emitting colors for driving potentials, thereby reducing the power consumption of the display panel 100.

[0106] In an embodiment where the first optical device 131 is a light-emitting device 135 and the second optical device 132 is a photosensitive device 136, a first potential can be provided to the light-emitting device 135 through the first power supply line 110, and a second potential can be provided to the photosensitive device 136 through the second power supply line 120. Thus, the first power supply line 110 and the second power supply line 120 respectively provide different potentials to the light-emitting device 135 and the photosensitive device 136 on the display panel 100, so that the potentials provided to the light-emitting device 135 and the photosensitive device 136 are separated, to respectively meet the requirements of the light-emitting device 135 and the photosensitive device 136 for driving potentials, avoid the potential of the light-emitting device 135 or the photosensitive device 136 from being too high, thereby reducing the power consumption of the display panel 100. In addition, it can also avoid the light-emitting device 135 and the photosensitive device 136 sharing the same potential and affecting their respective performances.

[0107] The following describes the third optical device 133 provided in the embodiments of the present application.

[0108] In some embodiments, referring to Figure 2 and Figure 3 , in the same repeating unit group 103, multiple optical devices 130 include a third optical device 133, and the third optical device 133 is a light-emitting device 135. In the adjacent first orthographic projection and second orthographic projection, and the third orthographic projection located between the first orthographic projection and the second orthographic projection, the first power supply line 110 corresponding to the first orthographic projection is electrically connected to the third optical device 133 of the repeating unit group 103 corresponding to the third orthographic projection, and the first power supply line 110 provides a first potential to the third optical device 133 of the repeating unit group 103. At this time, the first power supply line 110 can simultaneously provide the first potential to the first optical device 131 and the third optical device 133 of the repeating unit group 103, thereby reducing the number of power supply lines for providing potentials to the first optical device 131 and the third optical device 133, which is beneficial to reducing the manufacturing cost of the display panel 100. In addition, the second power supply line 120 is used to provide a second potential to the second optical device 132 of the repeating unit group 103, so that the potential provided to the second optical device 132 is separated from the potentials of the first optical device 131 and the third optical device 133 at the same time, which is beneficial to reducing the power consumption of the display panel 100.

[0109] Exemplarily, refer to Figure 2 , the first optical device 131, the second optical device 132, and the third optical device 133 are all light-emitting devices 135. The light-emitting colors of the first optical device 131, the second optical device 132, and the third optical device 133 are all different. A first potential can be provided to the light-emitting devices 135 of two of the colors through the first power supply line 110, and a second potential can be provided to the light-emitting device 135 of one color through the second power supply line 120. The light-emitting color of one of the first optical device 131, the second optical device 132, and the third optical device 133 is one of red, blue, and green. For example, the light-emitting color of one of the first optical device 131 and the third optical device 133 is blue, and the light-emitting color of the other is green, that is, the first power supply line 110 is electrically connected to the green light-emitting device and the blue light-emitting device to provide the first potential to the green light-emitting device and the blue light-emitting device. The light-emitting color of the second optical device 132 is red, that is, the second power supply line 120 is electrically connected to the red light-emitting device to provide the second potential to the red light-emitting device. In this way, the second potential of the red light-emitting device can be made different from the first potential of the green light-emitting device / blue light-emitting device to meet the requirements of light-emitting devices 135 with different light-emitting colors for different driving potentials.

[0110] Among them, since the potential required by the red light-emitting device is quite different from the potential required by the green light-emitting device / blue light-emitting device, and the potential difference between the green light-emitting device and the blue light-emitting device is relatively small, therefore, the red light-emitting device alone uses the second power supply line 120 to provide the second potential, and the green light-emitting device and the blue light-emitting device jointly use the first power supply line 110 to provide the first potential, which can make the first potential and the second potential better meet the requirements of the three light-emitting devices 135 for different driving potentials.

[0111] In other examples, refer to Figure 3 , the first optical device 131 and the third optical device 133 are both light-emitting devices 135, the second optical device 132 is a photosensitive device 136, and the light-emitting colors of the first optical device 131 and the third optical device 133 can be different. A first potential can be provided to the first optical device 131 and the third optical device 133 through the first power supply line 110, that is, the first power supply line 110 provides the first potential to the two light-emitting devices 135, and the second power supply line 120 provides the second potential to the photosensitive device 136, so that the potentials of the light-emitting device 135 and the photosensitive device 136 can be separated.

[0112] The following describes the fourth optical device 134 provided in the embodiments of the present application.

[0113] Refer to Figure 3 , in the same repeating unit group 103, multiple optical devices 130 include a fourth optical device 134, and the fourth optical device 134 is a light-emitting device 135.

[0114] Exemplarily, the emission colors of the first optical device 131, the third optical device 133, and the fourth optical device 134 are all different.

[0115] Exemplarily, when the second optical device 132 is the light-emitting device 135, the colors of the first optical device 131, the second optical device 132, the third optical device 133, and the fourth optical device 134 are all different.

[0116] In some embodiments, referring to Figure 3 , the first optical device 131, the third optical device 133, and the fourth optical device 134 are light-emitting devices 135, and the second optical device 132 is a photosensitive device 136. In adjacent first and second orthographic projections, and in a third orthographic projection located between the first orthographic projection and the second orthographic projection, the first power line 110 corresponding to the first orthographic projection is electrically connected to the fourth optical device 134 of the repeating unit group 103 corresponding to the third orthographic projection. The first power line 110 supplies a first potential to the fourth optical device 134 of the repeating unit group 103. At this time, the first power line 110 can simultaneously supply the first potential to the first optical device 131, the third optical device 133, and the fourth optical device 134 of the repeating unit group 103, thereby reducing the number of power lines for supplying potential to the first optical device 131, the third optical device 133, and the fourth optical device 134, which is beneficial to reducing the manufacturing cost of the display panel 100. Additionally, the second power line 120 is used to supply a second potential to the second optical device 132 of the repeating unit group 103, such that the second potential supplied to the second optical device 132 is different from the first potential supplied to the first optical device 131, the third optical device 133, and the fourth optical device 134, separating the second potential supplied to the second optical device 132 from the first potential of the first optical device 131, the third optical device 133, and the fourth optical device 134, and separating the potentials of the light-emitting device 135 and the photosensitive device 136, which is beneficial to reducing the power consumption of the display panel 100. Among them, the emission colors of the first optical device 131, the third optical device 133, and the fourth optical device 134 are all different. For example, the emission color of one of the first optical device 131, the third optical device 133, and the fourth optical device 134 is one of red, blue, and green.

[0117] It should be noted that the first power line 110 can be used to supply the first potential to the light-emitting device 135, and the same first power line 110 is electrically connected to at least one color of the light-emitting device 135. The second power line 120 can be used to supply the second potential to the light-emitting device 135. Alternatively, the second power line 120 can be used to supply the second potential to the photosensitive device 136, and the same second power line 120 is electrically connected to at least one color of the light-emitting device 135.

[0118] The following describes the first cross-bridge 151 provided in the embodiments of the present application.

[0119] In some embodiments, referring to Figure 4 , at least one first cross-bridge 151 is provided between two adjacent first power lines 110. For example, a plurality of first cross-bridges 151 arranged at intervals along the second direction B are provided between two adjacent first power lines 110. The first cross-bridge 151 can electrically connect two adjacent first power lines 110 together, enabling the two adjacent first power lines 110 to be connected in the first direction A, and can connect a plurality of first power lines 110 into a mesh structure, thereby improving the potential uniformity of each first power line 110, which is beneficial to improving the display uniformity of the display panel 100. Among them, the first cross-bridge 151 includes opposite first end 1511 and second end 1512, and the first end 1511 and the second end 1512 can be the two ends of the extending direction of the first cross-bridge 151.

[0120] In some examples, referring to Figure 4 , among two adjacent first power lines 110 and the first cross-bridge 151 located between the two first power lines 110, one of the first power lines 110 is electrically connected to the first end 1511 of the first cross-bridge 151, and the optical device 130 electrically connected to the other first power line 110 is electrically connected to the second end 1512 of the first cross-bridge 151. At this time, the other first power line 110 and the second end 1512 of the first cross-bridge 151 are both electrically connected to the same optical device 130. By electrically connecting the one first power line 110 to the other first power line 110 through the first cross-bridge 151, that is, by electrically connecting the two adjacent first power lines 110 through the first cross-bridge 151, a plurality of first power lines 110 can be connected into a mesh structure, which can improve the potential uniformity of each first power line 110, thereby being beneficial to improving the display uniformity of the display panel 100.

[0121] In some other examples, among two adjacent first power supply lines 110 and a first bridging member 151 located between the two first power supply lines 110, an optical device 130 electrically connected to one of the first power supply lines 110 is electrically connected to a first end 1511 of the first bridging member 151, and an optical device 130 electrically connected to the other first power supply line 110 is electrically connected to a second end 1512 of the first bridging member 151. Thus, one of the first power supply lines 110 is electrically connected to the other first power supply line 110 through the first bridging member 151, that is, the two adjacent first power supply lines 110 are electrically connected through the first bridging member 151. Multiple first power supply lines 110 can be connected into a mesh structure, which can improve the potential uniformity of each first power supply line 110, thereby being beneficial to improving the display uniformity of the display panel 100. In addition, compared with an example in which the first end 1511 of the first bridging member 151 is directly electrically connected to one of the first power supply lines 110, in this example, the first end 1511 of the first bridging member 151 and the optical device 130 electrically connected to one of the first power supply lines 110 are electrically connected, which is beneficial to shortening the extension length of the first bridging member 151.

[0122] Exemplarily, the current on the first power supply line 110 can be greater than the current on the second power supply line 120. By arranging the first bridging member 151, a mesh structure can be formed for the first power supply line 110 with a larger load current, which is beneficial to reducing the voltage drop on the first power supply line 110, thereby being beneficial to improving the display uniformity of the display panel 100.

[0123] In some embodiments, referring to Figure 4 , the second power supply line 120 includes a plurality of first sub-power supply lines 121 arranged at intervals along the second direction B. There is a first gap 161 between two adjacent first sub-power supply lines 121. The first bridging member 151 is correspondingly arranged with the first gap 161, and the first bridging member 151 penetrates through the corresponding first gap 161. The first bridging member 151 is arranged at an interval from the adjacent first sub-power supply lines 121. By arranging the first gap 161, it is avoided that the first bridging member 151 contacts the second power supply line 120. Two adjacent first sub-power supply lines 121 are connected by a first avoiding member 171. The first avoiding member 171 can connect two adjacent first sub-power supply lines 121 while avoiding the first bridging member 151, and prevent the first avoiding member 171 and the first bridging member 151 from contacting so that the first potential and the second potential cannot be separated. The first avoiding member 171 is correspondingly arranged with the first bridging member 151. The first avoiding member 171 is located on a side of the second end 1512 of the corresponding first bridging member 151 away from the first end 1511, and is arranged at an interval from the corresponding first bridging member 151, so that the first avoiding member 171 and the first bridging member 151 do not contact, so as to prevent the first power supply line 110 and the second power supply line 120 from being electrically connected and the first potential and the second potential from being unable to be separated.

[0124] Exemplarily, the first cross-bridge member 151 and the first power line 110 are arranged on the same layer and made of the same material, which is beneficial to simplifying the manufacturing process of the first cross-bridge member 151 and the first power line 110 and reducing the manufacturing cost.

[0125] Exemplarily, the first avoidance member 171 and the first power line 110 are arranged on the same layer and made of the same material, which is beneficial to simplifying the manufacturing process of the first avoidance member 171 and the first power line 110 and reducing the manufacturing cost.

[0126] Exemplarily, referring to Figure 4 , the first avoidance member 171 encloses to form a first avoidance opening 1711, and the second end 1512 of the first cross-bridge member 151 is located in the corresponding first avoidance opening 1711. For example, the shape of the first avoidance opening 1711 is adapted to the shape of the second end 1512 of the corresponding first cross-bridge member 151. Thus, while the first avoidance member 171 is beneficial to avoiding the second end 1512 of the corresponding first cross-bridge member 151, the distance between the first avoidance member 171 and the second end 1512 of the first cross-bridge member 151 can be relatively close, which is beneficial to reducing the total area of the display panel 100 occupied by the first avoidance member 171 and the first cross-bridge member 151 and is beneficial to reducing the occlusion of the optical device 130 by the first avoidance member 171 and the first cross-bridge member 151. Among them, the shape of the first avoidance opening 1711 being adapted to the shape of the second end 1512 of the corresponding first cross-bridge member 151 may mean that the shape of the first avoidance opening 1711 is substantially the same as the shape of the second end 1512 of the corresponding first cross-bridge member 151.

[0127] In some embodiments, referring to Figure 4 , the first cross-bridge member 151 includes a plurality of first extension segments 1531 and second extension segments 1532. Adjacent two first extension segments 1531 are connected by a second extension segment 1532, and the extension directions of adjacent first extension segments 1531 and second extension segments 1532 are different. By setting the first extension segments 1531 and the second extension segments 1532, the first cross-bridge member 151 can be bent according to requirements, and the occlusion of the optical device 130 by the first cross-bridge member 151 can be reduced.

[0128] Exemplarily, the first extension segment 1531 extends along the first direction A.

[0129] Exemplarily, the second extension segment 1532 extends along the second direction B.

[0130] The following describes the second cross-bridge member 152 provided by the embodiments of the present application.

[0131] In some embodiments, referring to Figure 5, at least one second cross-bridge 152 is disposed between two adjacent second power lines 120. For example, a plurality of second cross-bridges 152 arranged at intervals along the second direction B are disposed between two adjacent second power lines 120. The second cross-bridge 152 can electrically connect two adjacent second power lines 120 together, enabling the two adjacent second power lines 120 to achieve connection in the first direction A. A plurality of second power lines 120 can be connected into a mesh structure, which can improve the potential uniformity of each second power line 120, thereby being beneficial to improving the display uniformity of the display panel 100. Wherein, the second cross-bridge 152 includes opposite third end 1523 and fourth end 1524, and the third end 1523 and the fourth end 1524 can be the two ends of the extending direction of the second cross-bridge 152.

[0132] In some examples, referring to Figure 5 , among two adjacent second power lines 120 and the second cross-bridge 152 located between the two second power lines 120, one of the second power lines 120 is electrically connected to the third end 1523 of the second cross-bridge 152, and the optical device 130 electrically connected to the other second power line 120 is electrically connected to the fourth end 1524 of the second cross-bridge 152. At this time, the other second power line 120 and the fourth end 1524 of the second cross-bridge 152 are electrically connected to the same optical device 130. The second cross-bridge 152 electrically connects the one second power line 120 to the other second power line 120, that is, the second cross-bridge 152 electrically connects the two adjacent second power lines 120. A plurality of second power lines 120 can be connected into a mesh structure, which can improve the potential uniformity of each second power line 120, thereby being beneficial to improving the display uniformity of the display panel 100.

[0133] In other examples, among two adjacent second power lines 120 and the second cross-bridge 152 located between the two second power lines 120, the optical device 130 electrically connected to one of the second power lines 120 is electrically connected to the third end 1523 of the second cross-bridge 152, and the optical device 130 electrically connected to the other second power line 120 is electrically connected to the fourth end 1524 of the second cross-bridge 152. Thus, the one second power line 120 is electrically connected to the other second power line 120, that is, the second cross-bridge 152 electrically connects the two adjacent second power lines 120. A plurality of second power lines 120 can be connected into a mesh structure, which can improve the potential uniformity of each second power line 120, thereby being beneficial to improving the display uniformity of the display panel 100. In addition, compared with the example of directly electrically connecting the third end 1523 of the second cross-bridge 152 to the one second power line 120, in this example, the third end 1523 of the second cross-bridge 152 is electrically connected to the optical device 130 electrically connected to the one second power line 120, which is beneficial to shortening the extending length of the second cross-bridge 152.

[0134] It should be noted that in the embodiments of the present application, at least one of a first cross-bridge member 151 and a second cross-bridge member 152 can be provided. In an embodiment where both the first cross-bridge member 151 and the second cross-bridge member 152 are provided (for example, it can be applied to a display panel 100 with a resolution less than or equal to 300 ppi), a plurality of first power lines 110 and a plurality of second power lines 120 can respectively form a mesh structure, so that the potential uniformity of each first power line 110 and the potential uniformity of each second power line 120 are respectively improved, thereby better improving the display uniformity of the display panel 100. In the embodiment of the first cross-bridge member 151 or the second cross-bridge member 152, the number of cross-bridge members is less than that when both the first cross-bridge member 151 and the second cross-bridge member 152 are provided, so that the adverse impact of the cross-bridge members on the pixel design space can be reduced, which is beneficial to improving the aperture ratio and resolution of the display panel 100.

[0135] In some embodiments, referring to Figure 5 , the first power line 110 includes a plurality of second sub-power lines 112 arranged at intervals along the second direction B. There is a second gap 162 between two adjacent second sub-power lines 112. The second cross-bridge member 152 is correspondingly arranged with the second gap 162. The second cross-bridge member 152 passes through the corresponding second gap 162. The second cross-bridge member 152 is arranged at an interval from the adjacent second sub-power line 112. By setting the second gap 162, the second cross-bridge member 152 is prevented from contacting the first power line 110. Adjacent two second sub-power lines 112 are connected by a second avoidance member 172. The second avoidance member 172 can connect adjacent two second sub-power lines 112 while avoiding the second cross-bridge member 152, and prevent the first potential and the second potential from being unable to be separated due to the contact between the second avoidance member 172 and the second cross-bridge member 152. The second avoidance member 172 is correspondingly arranged with the second cross-bridge member 152. The second avoidance member 172 is located on the side of the fourth end 1524 of the corresponding second cross-bridge member 152 departing from the third end 1523, and is arranged at an interval from the corresponding second cross-bridge member 152, so that the second avoidance member 172 does not contact the second cross-bridge member 152, so as to prevent the first power line 110 and the second power line 120 from being electrically connected and the first potential and the second potential from being unable to be separated.

[0136] Exemplarily, the second cross-bridge member 152 and the first power line 110 are provided on the same layer and made of the same material, which is beneficial to simplifying the manufacturing process of the second cross-bridge member 152 and the first power line 110 and reducing the manufacturing cost.

[0137] Exemplarily, the second avoidance member 172 and the first power line 110 are provided on the same layer and made of the same material, which is beneficial to simplifying the manufacturing process of the second avoidance member 172 and the first power line 110 and reducing the manufacturing cost.

[0138] Exemplarily, refer to Figure 5 , the second avoidance member 172 encloses to form a second avoidance opening 1722, and the fourth end 1524 of the second cross-bridge member 152 is located in the corresponding second avoidance opening 1722. For example, the shape of the second avoidance opening 1722 is adapted to the shape of the fourth end 1524 of the corresponding second cross-bridge member 152. Thus, while facilitating the avoidance of the fourth end 1524 of the corresponding second cross-bridge member 152 by the second avoidance member 172, the distance between the second avoidance member 172 and the fourth end 1524 of the second cross-bridge member 152 can be made relatively close, which is beneficial to reducing the total area occupied by the second avoidance member 172 and the second cross-bridge member 152 on the display panel 100, and is beneficial to reducing the occlusion of the optical device 130 by the second avoidance member 172 and the second cross-bridge member 152.

[0139] In some embodiments, refer to Figure 6 , the second cross-bridge member 152 includes a plurality of third extension segments 1533 and fourth extension segments 1534. Adjacent third extension segments 1533 are connected by a fourth extension segment 1534, and the extension directions of adjacent third extension segments 1533 and fourth extension segments 1534 are different. By providing the third extension segments 1533 and the fourth extension segments 1534, the second cross-bridge member 152 can be bent according to requirements, and the occlusion of the optical device 130 by the second cross-bridge member 152 can be reduced.

[0140] Exemplarily, the third extension segment 1533 extends along the first direction A.

[0141] Exemplarily, the fourth extension segment 1534 extends along the second direction B.

[0142] In some embodiments, refer to Figure 1 and Figure 2 , the first power line 110 and the optical device 130 are electrically connected through a first connecting member 141, so that the shape of the first power line 110 is relatively simple, which is beneficial to reducing the manufacturing difficulty of the first power line 110.

[0143] In some embodiments, refer to Figure 1 and Figure 2 , the second power line 120 and the optical device 130 are electrically connected through a second connecting member 142, so that the shape of the second power line 120 is relatively simple, which is beneficial to reducing the manufacturing difficulty of the second power line 120.

[0144] Exemplarily, the first connecting member 141 is arranged on the same layer and made of the same material as the first power line 110, which is beneficial to simplifying the manufacturing process of the first connecting member 141 and the first power line 110 and reducing the manufacturing cost.

[0145] Exemplarily, the second connecting member 142 and the first power supply line 110 are arranged on the same layer and made of the same material, which is beneficial to simplifying the manufacturing process of the second connecting member 142 and the first power supply line 110 and reducing the manufacturing cost.

[0146] The following describes the pixel defining layer 194 provided in the embodiments of the present application.

In the embodiments of the present application, the case where the third electrode 1363 is the anode of the photosensitive device 136 and the fourth electrode 1364 is the cathode of the photosensitive device 136 is taken as an example for illustration.

[0165] The partition structure 180 provided in the embodiments of the present application will be further described below.

The partition structure 180 may define a plurality of partition openings 184, and the plurality of partition openings 184 may be arranged at intervals. The plurality of partition openings 184 are correspondingly arranged with the plurality of optical devices 130, and the optical devices 130 are at least partially disposed in the corresponding partition openings 184.

[0167] Exemplarily, the partition opening 184 may be correspondingly communicated with the pixel opening 1941.

[0168] Wherein, in the embodiments of the present application, the corresponding arrangement of A and B may mean that one A is correspondingly arranged with at least one B, or one B is correspondingly arranged with at least one A. In the embodiments of the present application, the case where one A is correspondingly arranged with one B is taken as an example for illustration. For example, the corresponding arrangement of the partition opening 184 and the optical device 130 may mean that one partition opening 184 is correspondingly arranged with at least one optical device 130, or one optical device 130 is correspondingly arranged with at least one partition opening 184.

[0169] In some embodiments, the partition structure 180 may refer to an undercut structure with a "large top and small bottom" structure that can separate the functional layers (light-emitting layer 1353 and / or photosensitive layer 1361) of two adjacent optical devices 130. The functional layers of multiple optical devices 130 are arranged at intervals, and the cathodes (second electrodes 1352 and / or fourth electrodes 1364) of multiple optical devices 130 are arranged at intervals. The partition structure 180 may be prepared first, and then the functional layers (light-emitting layer 1353 and / or photosensitive layer 1361) of the optical device 130 and the cathodes (second electrodes 1352 and / or fourth electrodes 1364) of the optical device 130 are prepared. In this way, by first forming the partition structure 180, when the functional layers of the optical device 130 and the cathodes of the optical device 130 are subsequently formed, the functional layers of the two adjacent optical devices 130 may be separated by the partition structure 180, and the cathodes of the two adjacent optical devices 130 may also be separated.

[0170] Exemplarily, the partition structure 180 may be a structure formed by a single film layer, or a structure formed by stacking a plurality of film layers.

[0180] In some embodiments, refer to Figure 5 , a positive projection of the second cross-bridge 152 on the substrate 101 overlaps with a positive projection of the partition structure 180 on the substrate 101, so that the total area of the display panel 100 occupied by the second cross-bridge 152 and the partition structure 180 is relatively small, which is beneficial to reducing the shielding of the optical device 130 by the second cross-bridge 152 and improving the aperture ratio of the display panel 100.
