Also, if the component is turned over, one layer or region may be "under" or "beneath" another layer or region.
On intelligent electronic devices such as mobile phones and tablet computers, photosensitive components such as a front camera, an infrared light sensor, and a proximity light sensor need to be integrated on a side where a display panel is disposed. In some embodiments, a transparent display area may be disposed on the electronic device, and the photosensitive component is disposed below the transparent display area, so that full-screen display of the electronic device is achieved under the condition that the photosensitive component is ensured to work normally.
Referring to fig. 1 and fig. 2, in order to ensure that the electronic device can further improve the transmittance under the condition of full display, the performance of the photosensitive element is further ensured. The embodiment of the invention provides a light-transmitting display panel 100, which includes a substrate 2 and a light-emitting device layer 1, wherein the light-emitting device layer 1 is located on the substrate 2. Alternatively, the Light-transmitting display panel 100 may be an Organic Light Emitting Diode (OLED) display panel.
In a specific implementation, the substrate 2 may be made of a light-transmitting material such as glass or Polyimide (PI).
Alternatively, the light emitting element layer 1 includes a pixel defining layer 10 and a plurality of light emitting elements 20, and the plurality of light emitting elements 20 are arranged in an array on the substrate 2. The pixel defining layer 10 includes a plurality of pixel openings 11, each of the light emitting elements 20 includes a first electrode 21, a light emitting structure 22 on the first electrode 21, and a second electrode 23 on the light emitting structure 22, and the light emitting structure 22 of each of the light emitting elements 20 is disposed in the pixel opening 11. Wherein the first electrode 21 of the at least one light emitting element 20 has a light transmitting region 215.
In the light-transmitting display panel 100 provided in the embodiment of the present invention, the light-transmitting area of the light-transmitting display panel 100 is reduced by providing the light-transmitting region on the first electrode 21, so as to improve the light transmittance of the light-transmitting display panel 100, thereby ensuring the performance of the light-sensing component, such as the shooting effect of the camera.
In some alternative examples, the polarities of the first electrode 21 and the second electrode 23 are opposite, and one of the first electrode 21 and the second electrode 23 may be an anode and the other may be a cathode. Alternatively, the first electrode 21 may be located between the substrate 2 and the second electrode 23. In order to better understand the light-transmitting display panel 100 provided by the embodiment of the invention, the following description will be made by taking the first electrode 21 as an anode and the second electrode 23 as a cathode.
Optionally, in practical implementation, the light-transmitting region 215 may be disposed on the first electrode 21 of all the light-emitting elements 20 of the light-transmitting display panel 100. Of course, in order to balance the requirements of light transmittance and display effect, the light-transmitting region 215 may be disposed on the first electrode 21 of a part of the light-emitting elements 20 of the light-transmitting display panel 100.
The light-transmitting region 215 mentioned may not be particularly limited in shape as long as it can be ensured that the light transmitted at the position of the light-transmitting region 215 is increased in the thickness direction X of the substrate 2 as compared with before the light-transmitting region 215 is not provided. In some alternative examples, the light-transmitting region 215 may be a region where a material is removed after a portion of the material is removed on the first electrode 21, and the region may be referred to as the light-transmitting region 215.
Alternatively, the first electrode 21 is provided with the light emitting element 20 having the light transmitting region 215, and the light transmitting region 215 is disposed opposite to the pixel opening 11 where the light emitting element 20 is located, or the first electrode 21 is provided with the light emitting element 20 having the light transmitting region 215, and the projection of the light transmitting region 215 on the substrate 2 is staggered from the projection of the pixel defining layer 10 on the substrate 2. Through the above arrangement, the light-transmitting region 215 can be better ensured to be used for light-transmitting effectiveness, and further, the light transmittance of the light-transmitting display panel 100 is optimized.
As an alternative implementation manner, in the light-transmitting display panel 100 provided in each of the above embodiments, the number of the light-transmitting regions 215 disposed on the first electrode 21 is two or more and is spaced from each other. Through the above arrangement, the light transmittance of the light-transmitting display panel 100 can be further improved, and meanwhile, the electrical property requirement of the first electrode 21 can be ensured through the arrangement, so that the display effect of the light-transmitting display panel 100 is ensured.
In some alternative embodiments, the first electrode 21 includes two light-transmitting conductive layers 211 disposed at intervals along the thickness direction X of the substrate 2, and a reflective layer 212 sandwiched between the two light-transmitting conductive layers 211.
Optionally, along the thickness direction X of the substrate 2, a plurality of first openings 212a are disposed on the reflective layer 212, a light-transmitting region 215 is formed in a region where each first opening 212a is located, and the shape of the first opening 212a may be set according to requirements, and may be one of other polygons such as a circle, an ellipse, and a rectangle. Of course, the structure form of the irregular shape can be set according to the requirement. The sidewall enclosing the first opening 212a may be a closed loop structure, or may be an open loop structure having an open opening. Because the light-transmitting conducting layers 211 arranged at two intervals can transmit light, and the first openings 212a are arranged, light can be transmitted through the first openings 212a, so that the light transmittance can be improved, and the display requirement of the light-transmitting display panel 100 can be ensured.
Optionally, the reflective layer 212 is divided into two or more reflective blocks by the first openings 212a, and the transparent region 215 is located between two adjacent reflective blocks. Optionally, the material of the light-transmitting conductive layer 211 includes at least one of Indium Tin Oxide (ITO) and Indium zinc oxide (izo), and the material of the reflective layer 212 includes silver.
Referring to fig. 3 and fig. 4, optionally, a second opening 211a opposite to the first opening 212a of the reflective layer 212 is disposed on one of the two transparent conductive layers 211 of the same first electrode 21, and by the above arrangement, the light transmittance of the transparent display panel 100 can be further improved.
As shown in fig. 5, in some alternative embodiments, the two light-transmissive conductive layers 211 of the same first electrode 21 are respectively provided with the second openings 211a, and by such arrangement, the light transmittance of the light-transmissive display panel 100 can be further optimized. At the same time, the molding of the first electrode 21 is facilitated.
Optionally, the light-transmitting conductive layer 211 provided with the second opening 211a is divided into light-transmitting conductive blocks having the same number and shape as the reflective blocks, when the two light-transmitting conductive layers 211 are both provided with the second opening 211a, each reflective block and the two transparent conductive blocks clamping the reflective block in the thickness direction X of the substrate 2 form an electrode block 21a together, and the light-transmitting region 215 is formed between the two adjacent electrode blocks 21a and penetrates through the first electrode 21.
Referring to fig. 6, as an alternative embodiment, more than two electrode blocks 21a of the same first electrode 21 are electrically connected to each other. Through the arrangement, the first electrode 21 can better meet the light-emitting requirement of the corresponding light-emitting structure 22, and the control of more than two electrode blocks 21a is facilitated.
In some alternative examples, two or more electrode blocks 21a of the same first electrode 21 are electrically connected to each other through a conductive wire 213, and the conductive wire 213 may be a non-transparent conductive wire, but is preferably a transparent conductive wire to further optimize the light transmittance.
Optionally, in practical implementation, in order to facilitate the molding of the first electrode 21, the material of the conducting wire 213 may be the same as that of the reflective block, and of course, preferably, the material of the light-transmitting conductive block, and the conducting wire 213 may be disposed in the same layer as the reflective layer 212 or one of the light-transmitting conductive layers 211.
As shown in fig. 7 and 8, it is understood that electrically connecting two or more electrode blocks 21a to each other through the conducting wires 213 is only an alternative embodiment, and in some other examples, two or more electrode blocks 21a of the same first electrode 21 may also be electrically connected to each other through the transparent connecting layer 214. The transparent connection layer 214 is disposed between the first electrode 21 and the light emitting element layer 1, and a projection of the transparent connection layer 214 on the substrate 2 covers the light transmission regions 215 of the same first electrode 21, where the transparent connection layer covers all of each light transmission region 215, or partially covers each light transmission region 215. Through the arrangement, the requirement of electric connection between the electrode blocks 21a can be met, and meanwhile, the reliability of electric connection can be guaranteed.
It is understood that when two or more electrode blocks 21a of the same first electrode 21 are connected by the transparent connection layer 214, the transparent connection layer 214 is not limited to be disposed between the first electrode 21 and the light emitting structure 22, and in some other examples, the transparent connection layer 214 may also be disposed between the first electrode 21 and the substrate 2, which can also satisfy the electrical connection requirement.
As an alternative embodiment, referring to fig. 1 to fig. 8, the light-transmitting display panel 100 provided by the above embodiments of the present invention may further include a device layer 3. The device layer 3 is provided between the substrate 2 and the light emitting element layer 1 and has a plurality of pixel circuits, and all the electrode blocks 21a of each first electrode 21 are connected to the same pixel circuit. Through the above arrangement, the control of the electrode block 21a is facilitated, and the display effect of the light-transmitting display panel 100 is ensured.
The pixel circuit may actually include elements such as a Thin-film transistor (TFT), a capacitor, and the like, which are interconnected as necessary.
As an alternative embodiment, the device layer 3 further includes a wiring structure 31, an orthogonal projection of the reflective block on the substrate 2 covers an orthogonal projection of a part of the wiring structure 31 on the substrate 2, and/or an orthogonal projection of a wall surface enclosing the light-transmitting region 215 on the substrate 2 is offset from an orthogonal projection of the wiring structure 31 on the substrate 2. Through the above arrangement, the light-tight area of the light-transmitting display panel 100 can be further reduced, and further the light transmittance of the light-transmitting display panel 100 is better optimized.
The mentioned wiring structure may be a metal layer connecting the pixel circuit and the first electrode 21 or other light-opaque metal layers in the device layer 3, or the like.
Optionally, in the light-transmitting display panel 100 provided in each of the above embodiments, the second Electrode 23 may be made of a metal-like material such as a Conductive Electrode Material (CEM), for example, a magnesium-silver alloy.
For example, the transparent display panel 100 may further include an encapsulation layer, and a polarizer and a cover plate located above the encapsulation layer, or the cover plate may be directly disposed above the encapsulation layer, without disposing a polarizer, so as to avoid the polarizer from affecting the light collection amount of the photosensitive element disposed below the transparent display panel 100, and of course, the polarizer may also be disposed above the encapsulation layer of the transparent display panel 100.
Thus, the light-transmitting display panel 100 according to the embodiment of the invention includes the substrate 2 and the light-emitting device layer 1, and the light-emitting device layer 1 includes the first electrode 21, the light-emitting structure 22 on the first electrode 21, and the second electrode 23 on the light-emitting structure 22. Because the first electrode 21 of at least one light-emitting element 20 is provided with the light-transmitting area 215, the light-tight area caused by the structure of the first electrode 21 can be reduced, the light transmittance of the light-transmitting display panel 100 is improved, and the performance of the photosensitive assembly is further ensured, such as the shooting effect of a camera can be ensured.

In a specific implementation, the first display area AA1 may adopt the transmissive display panel 100 provided in the above embodiments, and the structural form of the second display area AA2 may be different from the structural form of the first display area AA 1. For example, the second display area AA2 may be a conventional OLED display area, and the light-transmitting area 215 may not be disposed on the first electrode 21 corresponding to each light-emitting element 20, as long as it can ensure better display effect.
The arrangement of the orthographic projection of the light emitting structure 22 of the light emitting element layer 1 of the second display area AA2 on the substrate 2 may be different from the arrangement of the orthographic projection of the light emitting structure 22 of the first display area AA1 on the substrate 2. Also, in consideration of the display effect, the pixel opening 11 on the pixel defining layer 10 of the light emitting element layer 1 of the second display area AA2 may be larger than the pixel opening 11 of the pixel defining layer 10 of the first display area AA1, and may be specifically set as required as long as the predetermined display and light transmission requirements can be satisfied.
Therefore, the display panel 200 according to the embodiment of the present invention includes the light-transmitting display panel 100 according to the above embodiments, so that at least the first electrode 21 located in the first display area AA1 is provided with the light-transmitting area 215, which can reduce the light-proof area caused by the structure of the first electrode 21, and improve the light transmittance of the display panel 200.

The display device 300 further includes a photosensitive member 310, and the photosensitive member 310 is located on the second surface S2 side of the light-transmissive display panel 100.
The photosensitive component 310 may be an image capturing device for capturing external image information, such as a camera. It is understood that the photosensitive component 310 may not be limited to an image capture device, for example, in some embodiments, the photosensitive component 310 may also be an infrared sensor, a proximity sensor, an infrared lens, a flood sensing element, an ambient light sensor, a dot matrix projector, and the like. In addition, the display device 300 may further integrate other components, such as an earpiece, a speaker, etc., on the second surface S2 of the light-transmissive display panel 100.
According to the display device 300 provided by the embodiment of the invention, since the display device comprises the light-transmitting display panel 100 of each embodiment, and the light-transmitting display panel 100 has a better light-transmitting effect, the second surface S2 of the light-transmitting display panel 100 can be integrated with the photosensitive component 310, so as to realize the under-screen integration of the photosensitive component 310, such as an image acquisition device, and meanwhile, the first surface S1 can display pictures, so as to realize the overall screen design of the display device 300.
