[0056] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are provided 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 of the present application more thorough and comprehensive.

[0057] It should be understood that although the terms "first", "second", etc. may be used herein to describe various elements, they do not represent any order, quantity or importance, but are only used to distinguish different components. These terms are only used to distinguish one element from another element. 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. "Including" or "comprising" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0058] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application 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.

[0059] As described in the background technology, in order to maximize the transmittance of transparent display, in the relevant transparent display technology, the driving circuit and the light-emitting pixels are usually compressed to the extreme, and the signals are transmitted by horizontal signal lines and vertical signal lines, and the remaining areas are all used as light-transmitting areas. Generally, the driving circuit and the light-emitting pixels overlap in the vertical space. However, on the one hand, the occupied area of ​​the light-emitting pixels is relatively limited, resulting in a shorter life of the light-emitting pixels; on the other hand, when the screen brightness needs to be increased, the current density will increase sharply, resulting in increased aging of the light-emitting pixels, further reducing the life of the transparent display panel.

[0060] In view of this, the embodiments of the present application provide a transparent display panel and a display device, by arranging at least part of the pixel unit in the circuit area and the wiring area of ​​the corresponding sub-area. In this way, since the circuit area is originally provided with a driving circuit group, and the wiring area is originally provided with a sub-wiring group, at least part of the pixel unit is arranged in the circuit area and the wiring area. On the one hand, the position arrangement of the pixel unit will not affect the transmittance of the light-transmitting area, which is conducive to making the transparent display panel have a higher transmittance; on the other hand, the space of the circuit area and the wiring area is used to arrange the pixel unit, which is conducive to expanding the arrangement area of ​​the pixel unit, thereby facilitating the improvement of the aperture ratio, and further facilitating the improvement of the display effect and service life.

[0061] In a first aspect, an embodiment of the present application provides a transparent display panel, which may be an organic light-emitting semiconductor (Organic Light-Emitting Diode, OLED) display panel, a liquid crystal display (Liquid Crystal Display, LCD), a sub-millimeter light-emitting diode (Mini Light-Emitting Diode, Mini LED) display panel, a micron light-emitting diode (Micro Light-Emitting Diode, Micro LED) display panel or a quantum dot electroluminescent (Quantum Dot Light Emitting Diodes, QLED) display panel.

[0062] Specifically, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the transparent display panel 10 has a plurality of sub-areas 10a. Each sub-area 10a includes a light-transmitting area 10a1, a circuit area 10a2 and a wiring area 10a3. The light-transmitting area 10a1 is used to transmit light, the circuit area 10a2 is used to set the driving circuit, and the wiring area 10a3 is used to set the wiring. It can be understood that the plurality of sub-areas 10a can be arranged at intervals from each other or arranged adjacent to each other.

[0063] Furthermore, the transparent display panel 10 includes a substrate 11, a plurality of pixel units 12, a plurality of drive circuit groups 13 and a plurality of sub-wiring groups 14. The substrate 11 may be a flexible transparent substrate 11, such as a polyimide (PI) substrate 11, or a rigid transparent substrate 11, such as glass.

[0064] The plurality of pixel units 12 are arranged on one side of the substrate 11, and correspond to the plurality of sub-areas 10a one by one. At least part of each pixel unit 12 is located in the circuit area 10a2 and the routing area 10a3 of the corresponding sub-area 10a. The plurality of drive circuit groups 13 are arranged between the substrate 11 and the pixel unit 12, and correspond to the plurality of sub-areas 10a one by one. Each drive circuit group 13 is located in the circuit area 10a2 of the corresponding sub-area 10a, and is electrically connected to the pixel unit 12 corresponding to the sub-area 10a. The plurality of sub-routing groups 14 are arranged between the substrate 11 and the pixel unit 12, and correspond to the plurality of sub-areas 10a one by one. Each sub-routing group 14 is located in the routing area 10a3 of the corresponding sub-area 10a, and is electrically connected to the drive circuit group 13 corresponding to the sub-area 10a.

[0065] It can be understood that the driving circuit group 13 is used to drive the pixel unit 12 to emit light, and the sub-wiring group 14 is used to transmit electrical signals to the driving circuit group 13. Specifically, the pixel unit 12 includes a plurality of sub-pixels, the driving circuit group 13 includes a plurality of driving circuits, each driving circuit is electrically connected to a corresponding sub-pixel, and the sub-wiring group 14 includes a plurality of signal wirings, each driving circuit is electrically connected to a corresponding signal wiring. The sub-wiring group 14 may include one or more layers of metal. After research, the inventor found that the number of signal wirings in a wiring area 10a3 is about four on average, and the width of the wiring area 10a3 is about 15μm-20μm, thereby allowing the wiring area 10a3 to have a certain space to set up a partial structure of the pixel unit 12.

[0066] The transparent display panel 10 provided in the embodiment of the present application is provided with at least part of the pixel unit 12 in the circuit area 10a2 and the wiring area 10a3 of the corresponding sub-area 10a. In this way, since the circuit area 10a2 is originally provided with the driving circuit group 13, and the wiring area 10a3 is originally provided with the sub-wiring group 14, at least part of the pixel unit 12 is provided in the circuit area 10a2 and the wiring area 10a3. On the one hand, the position arrangement of the pixel unit 12 will not affect the transmittance of the light-transmitting area 10a1, which is conducive to making the transparent display panel 10 have a higher transmittance; on the other hand, the space of the circuit area 10a2 and the wiring area 10a3 is used to arrange the pixel unit 12, which is conducive to expanding the arrangement area of ​​the pixel unit 12, avoiding space waste, thereby facilitating the improvement of the pixel aperture ratio, and further facilitating the improvement of the display effect and service life.

[0067] In one embodiment, the orthographic projection of the pixel unit 12 on the substrate 11 overlaps with at least a portion of the orthographic projection of the corresponding driving circuit group 13 on the substrate 11. Here, the orthographic projection of the pixel unit 12 on the substrate 11 refers to: the projection of the pixel unit 12 on the substrate 11 along the thickness direction of the substrate 11. The orthographic projection of the driving circuit group 13 on the substrate 11 refers to: the projection of the driving circuit group 13 on the substrate 11 along the thickness direction of the substrate 11.

[0068] The above arrangement can make the pixel unit 12 and the driving circuit group 13 overlap in the thickness direction of the substrate 11, which is beneficial to maximize the space utilization.

[0069] It is understandable that the orthographic projection of the pixel unit 12 on the substrate 11 and the orthographic projection of the corresponding driving circuit group 13 on the substrate 11 may not overlap.

[0070] In one embodiment, the orthographic projection of the pixel unit 12 on the substrate 11 overlaps with at least a portion of the orthographic projection of the corresponding sub-wiring group 14 on the substrate 11. Here, the orthographic projection of the sub-wiring group 14 on the substrate 11 refers to: the projection of the sub-wiring group 14 on the substrate 11 along the thickness direction of the substrate 11.

[0071] The above arrangement can make the pixel unit 12 and the sub-wiring group 14 overlap in the thickness direction of the substrate 11, which is beneficial to maximize the space utilization.

[0072] It is understandable that the orthographic projection of the pixel unit 12 on the substrate 11 and the orthographic projection of the corresponding sub-wiring group 14 on the substrate 11 may not overlap.

[0073] In one embodiment, the pixel unit 12 includes a first sub-pixel 121, a second sub-pixel 122, and a third sub-pixel 123, and the first sub-pixel 121, the second sub-pixel 122, and the third sub-pixel 123 are respectively used to emit light of different colors. Exemplarily, the first sub-pixel 121, the second sub-pixel 122, and the third sub-pixel 123 can be an R pixel, a G pixel, and a B pixel, respectively.

[0074] At least a portion of at least one of the first sub-pixel 121, the second sub-pixel 122, and the third sub-pixel 123 is located in the circuit area 10a2; at least a portion of at least one of the first sub-pixel 121, the second sub-pixel 122, and the third sub-pixel 123 is located in the wiring area 10a3. In this way, the sub-pixel arrangement in the pixel unit 12 can be more diverse, which is beneficial for designers to design the arrangement positions of the first sub-pixel 121, the second sub-pixel 122, and the third sub-pixel 123 according to actual needs, thereby facilitating a better display effect when the opening area is increased.

[0075] It should be noted that the first sub-pixel 121 may include a first anode, a first light-emitting portion, and a first cathode, the second sub-pixel 122 may include a second anode, a second light-emitting portion, and a second cathode, and the third sub-pixel 123 may include a third anode, a third light-emitting portion, and a third cathode. It is understandable that arranging the positions of the first sub-pixel 121, the second sub-pixel 122, and the third sub-pixel 123 in the pixel unit 12 is equivalent to arranging the positions of the first anode, the second anode, and the third anode. Further, when the first sub-pixel 121 is divided into a plurality of first sub-portions 1211, the first anode is also divided into a plurality of sub-structures. The second anode and the third anode are similar and will not be described in detail here.

[0076] In one embodiment, referring to Figure 6-Figure 10As shown, the orthographic projection of at least one of the first sub-pixel 121, the second sub-pixel 122, and the third sub-pixel 123 on the substrate 11 overlaps with the orthographic projection of the corresponding driving circuit group 13 on the substrate 11. The orthographic projection of at least one of the first sub-pixel 121, the second sub-pixel 122, and the third sub-pixel 123 on the substrate 11 overlaps with the orthographic projection of the corresponding sub-wiring group 14 on the substrate 11.

[0077] In this way, under the premise of making the sub-pixels in the pixel unit 12 arranged in a more diverse manner, it is beneficial to maximize the space utilization.

[0078] In one embodiment, the sub-area 10a includes a circuit area 10a2, a plurality of light-transmitting areas 10a1, and a plurality of routing areas 10a3. The plurality of routing areas 10a3 are arranged at intervals on the periphery of the circuit area 10a2. The plurality of light-transmitting areas 10a1 are arranged at intervals on the periphery of the circuit area 10a2. A routing area 10a3 is provided between any two adjacent light-transmitting areas 10a1. In this way, on the one hand, it is conducive to the reasonable arrangement of the sub-routing group 14; on the other hand, it is conducive to the more uniform arrangement of the light-transmitting areas 10a1, so that the light-transmitting performance of the sub-area 10a is more uniform.

[0079] It can be understood that the embodiment of the present application does not specifically limit the number and shape of the circuit area 10a2, the light-transmitting area 10a1, and the routing area 10a3.

[0080] In one embodiment, the sub-area 10a includes four light-transmitting areas 10a1 and four routing areas 10a3. Two routing areas 10a3 are located on opposite sides of the circuit area 10a2 along the first direction X, and two routing areas 10a3 are located on opposite sides of the circuit area 10a2 along the second direction Y. Along the circumferential direction of the circuit area 10a2, a light-transmitting area 10a1 is provided between any two routing areas 10a3. The first direction X and the second direction Y intersect. In this way, it is beneficial to arrange the sub-routing group 14 along the horizontal and vertical directions of the transparent display panel 10.

[0081] In one embodiment, the first direction X and the second direction Y are perpendicular.

[0082] In one embodiment, if Figure 1 As shown, a plurality of sub-areas 10a are arranged in rows along the first direction X and in columns along the second direction Y; any two adjacent sub-areas 10a are connected. In this way, the light-transmitting area 10a1 and the non-light-transmitting area of ​​the transparent display panel 10 can be arranged more evenly.

[0083] In one embodiment, referring to Figure 6 and Figure 7As shown, a portion of any one of the first sub-pixel 121, the second sub-pixel 122 and the third sub-pixel 123 is located in the circuit area 10a2, and another portion of any one of them is located in the wiring area 10a3. In this way, the sub-pixel arrangement in the pixel unit 12 can be more diverse, which is beneficial for designers to design the arrangement positions of the first sub-pixel 121, the second sub-pixel 122 and the third sub-pixel 123 according to actual needs, thereby facilitating a better display effect when the opening area is increased.

[0084] In one embodiment, referring to Figure 6 As shown, the first sub-pixel 121 includes a first main body 1212 and a first sub-part 1211. The first main body 1212 is located in the circuit area 10a2, and the first sub-part 1211 is located in the wiring area 10a3. The second sub-pixel 122 includes a second main body 1222 and a second sub-part 1221. The second main body 1222 is located in the circuit area 10a2, and the second sub-part 1221 is located in the wiring area 10a3. The third sub-pixel 123 includes a third main body 1232 and a third sub-part 1231. The third main body 1232 is located in the circuit area 10a2, and the third sub-part 1231 is located in the wiring area 10a3.

[0085] In this way, the first sub-pixel 121 , the second sub-pixel 122 , and the third sub-pixel 123 can be arranged more evenly in the circuit area 10 a 2 and the wiring area 10 a 3 , which is beneficial to improving the display effect.

[0086] In a specific example, referring to Figure 2 and Figure 5 As shown, the first sub-pixel 121 includes a first main body 1212 and four first sub-parts 1211, the second sub-pixel 122 includes a second main body 1222 and four second sub-parts 1221, and the third sub-pixel 123 includes a third main body 1232 and four third sub-parts 1231. A first sub-part 1211, a second sub-part 1221 and a third sub-part 1231 are provided in each routing area 10a3. In each routing area 10a3, the first sub-part 1211, the third sub-part 1231 and the second sub-part 1221 are arranged at intervals in a direction away from the circuit area 10a2. In this way, the first sub-pixel 121, the second sub-pixel 122 and the third sub-pixel 123 can be arranged more evenly in the circuit area 10a2 and the routing area 10a3, which is conducive to improving the display effect.

[0087] Further, the first main body 1212 and the four first sub-parts 1211 are connected as a whole through the first connecting line 151. In this way, the first sub-pixel 121 can be made as a whole, and the driving circuit group 13 can drive the first main body 1212 and the first sub-part 1211 to emit light synchronously, thereby realizing one driving multiple. The second main body 1222 and the four second sub-parts 1221 are connected as a whole through the second connecting line 152. In this way, the second sub-pixel 122 can be made as a whole, and the driving circuit group 13 can drive the second main body 1222 and the second sub-part 1221 to emit light synchronously, thereby realizing one driving multiple.
