The embodiments provided by the embodiments of the present invention may be combined with each other without contradiction.
In an electronic device such as a mobile phone and a tablet computer, it is necessary to integrate optical elements such as a front camera, an infrared light sensor, a proximity light sensor, and the like on the side where the display panel is provided. In some embodiments, a first display area may be disposed on the electronic device, and the optical element may be disposed on a back surface of the light-transmitting first display area, so as to implement a full-screen display of the electronic device under a condition that the optical element is ensured to work normally.
However, the present display panel structure is limited, and display difference exists between the first display area and the second display area, which affects the use experience of the user.
In order to solve the above problems, embodiments of the present invention provide a display panel and a display device, and embodiments of the display panel and the display device will be described below with reference to the accompanying drawings.
The display panel provided by the embodiment of the invention can be an Organic Light-Emitting Diode (OLED) display panel, a liquid crystal panel or a Micro-plane display panel (Micro-OLED or Micro-LED) and the like. The following will take an example in which the display panel is an OLED display panel.
Referring to fig. 1 to 4, an embodiment of the present invention provides a display panel having a first display area AA1 and a second display area AA2 at least partially surrounding the first display area AA1, the display panel comprising: a substrate 1; a pixel defining layer 2 disposed on one side of the substrate 1, the pixel defining layer 2 including a plurality of pixel openings; the electrode layer is at least partially arranged in the pixel opening, the electrode layer comprises a plurality of first electrode blocks 3 arranged in the first display area AA1, each first electrode block 3 is arranged in a layered mode in the direction perpendicular to the plane of the substrate 1, and orthographic projections of each first electrode block 3 on the substrate 1 are not overlapped.
The display panel provided by the embodiment of the invention comprises a substrate 1, a pixel definition layer 2 and an electrode layer, wherein the electrode layer comprises first electrode blocks 3, each first electrode block 3 is arranged in a layered manner along the direction perpendicular to the plane of the substrate 1, namely, each first electrode block 3 is respectively arranged at different height positions of the pixel definition layer 2 so as to avoid mutual interference of the first electrode blocks 3 between the layers, and compared with the arrangement of each first electrode block 3 at the same layer, each first electrode block 3 is arranged in the same layer in a layered manner so as to reserve more wiring space, and further more first electrode blocks 3 are arranged, so that the pixel density of the display panel in a first display area AA1 is improved, the pixel density difference of the first display area AA1 and a second display area AA2 is reduced, and the uniformity of the display brightness of the first display area AA1 and the second display area AA2 is ensured.
It should be noted that, the electrode layer provided by the embodiment of the invention may be an anode layer and/or a cathode layer, when the electrode layer is an anode layer, each anode block is layered, and the corresponding cathode layer may be layered corresponding to each anode block, or may be disposed entirely, so as to ensure the display effect. Similarly, when the electrode layer is a cathode layer, each cathode block is layered, and the corresponding anode block may be layered or may be co-layered, and is not particularly limited. In the embodiment of the present invention, fig. 2 to fig. 4 each illustrate an electrode layer as an anode layer.
It can be understood that the orthographic projection of each first electrode block 3 on the substrate 1 is set to be misaligned, so as to avoid the occurrence of shielding of the first electrode blocks 3 located in different layers, which affects the normal light-emitting efficiency of the display panel, for example, the first electrode block 3 located in the upper layer may cause shielding of the first electrode block 3 located in the lower layer, which affects the light-emitting of the organic light-emitting layer corresponding to the first electrode block 3.
Optionally, an organic light-emitting layer and a cathode layer are sequentially stacked on each first electrode block 3 to form a light-emitting unit, so as to realize light-emitting display of the display panel. In the related art, since the area size of the first display area AA1 is smaller, when the first electrode blocks 3 are disposed in the same layer, the routing space of each first electrode block 3 is limited, and the distribution density of the first electrode blocks 3 is smaller than that of the anode blocks of the second display area AA2, so that the first display area AA1 and the second display area AA2 have a more obvious display difference when the display panel is displaying. In order to solve this problem, in the display panel provided by the embodiment of the invention, the first electrode blocks 3 in the first display area AA1 are layered in the direction perpendicular to the plane on which the substrate 1 is located, so that the first electrode blocks 3 in different layers can respectively use the space of each layer to perform line walking, the number of the first electrode blocks 3 which can be set in the first display area AA1 is increased, the pixel density of the first display area AA1 is further improved, and the display uniformity of the first display area AA1 and the second display area AA2 is ensured.
The organic light emitting layer includes at least one of a hole injection layer, a hole transport layer, an electron injection layer, or an electron transport layer according to design requirements of the light emitting unit.
Meanwhile, as each first electrode block 3 is layered along the direction perpendicular to the plane of the substrate 1, that is, when the light emitting units corresponding to each first electrode block 3 emit light under different gradients, the optical gradient principle can be utilized to compensate the light at different angles, so that the sensitivity of the camera of the first display area AA1 to the external light is reduced, and the imaging effect is improved.
Optionally, the display panel has a first display area AA1 and a second display area AA2, where the light transmittance of the first display area AA1 is greater than the light transmittance of the second display area AA 2. In some alternative embodiments, the display panel further includes a non-display area surrounding the second display area AA 2.
Optionally, the light transmittance of the first display area AA1 is greater than or equal to 15%. In order to ensure that the light transmittance of the first display area AA1 is greater than 15%, even greater than 40%, even higher, the light transmittance of each functional film layer of the display panel in this embodiment is greater than 80%, and even the light transmittance of at least part of the functional film layers is greater than 90%.
In some alternative embodiments, the first electrode blocks 3 located in different layers are distributed in a ring shape; preferably, the first electrode blocks 3 located in different layers are distributed in concentric circles.
It should be noted that, the first display area AA1 is used for setting optical elements such as a camera and a fingerprint identification element, and specifically, the first display area AA1 includes an optical element reserved area TA for setting the optical elements, and each first electrode block 3 located on different layers may be distributed in a ring shape so as to be disposed around the optical element reserved area TA, so as to avoid the light entering amount of the optical element, ensure the normal operation of the optical element, and in order to ensure the light emitting uniformity of the light emitting unit corresponding to each first electrode block 3 located on different layers, each first electrode block 3 located on different layers is distributed in a concentric ring shape, so as to improve the uniformity of light emitting.
In order to send driving signals to each first electrode block 3, in some alternative embodiments, the display panel further includes first wires 4, each first wire 4 is disposed in the same layer as each first electrode block 3 correspondingly connected, and the first wires 4 are transparent wires.
It should be noted that, since the first display area AA1 needs to be correspondingly provided with the optical element, in order to ensure that the light transmittance of the first display area AA1 can meet the working requirement of the optical element, the first trace 4 is a transparent trace, and specifically, the material of the first trace 4 includes at least one of Indium Tin Oxide (ITO), indium Zinc Oxide (IZO), aluminum Zinc Oxide (AZO), gallium doped zinc oxide (GZO), zinc Tin Oxide (ZTO), gallium Tin Oxide (GTO), fluorine doped tin oxide (FTO), zinc oxide (ZnOx), indium oxide (InOx), polyethylene dioxythiophene-polystyrene sulfonate PEDOT: PSS, graphene and carbon nanotube. When the material of the first trace 4 includes at least one of the above materials, it is possible to ensure that the first trace 4 has high light transmittance and also to enable the first trace 4 to conduct electricity.
In order to minimize the effect of the first tracks 4 on the light transmittance, in some alternative embodiments, the orthographic projections of the first tracks 4 located in different layers on the substrate 1 at least partially coincide.
It can be understood that the orthographic projections of the first traces 4 located in different layers on the substrate 1 at least partially overlap, that is, the orthographic projections of the first traces 4 overlapping can affect the light output of the same area, but not affect the light output of a plurality of different areas, so that the shielding area of the first traces 4 is reduced, and the light transmittance of the first display area AA1 is further improved.
In order to further ensure the brightness uniformity of the display panel in the first display area AA1 and the second display area AA2, the display panel further comprises an array layer disposed between the substrate 1 and the pixel defining layer 2, the array layer comprising a second pixel driving circuit D2 and a first pixel driving circuit D1; the electrode layer further includes a second electrode block 6 disposed in the second display area AA2, the first electrode block 3 is electrically connected to the first pixel driving circuit D1, the second electrode block 6 is electrically connected to the second pixel driving circuit D2, and the first pixel driving circuit D1 and the second pixel driving circuit D2 are connected to voltage signal lines with the same voltage.
It should be noted that, due to the abundance of the wiring space of the second display area AA2, the second pixel driving circuit D2 generally employs a 7T1C circuit, and the wiring space of the first display area AA1 is tense, a 1T1C circuit may be employed, where "1T1C circuit" refers to the second pixel driving circuit D2 including 1 thin film transistor T and 1 capacitor C in the second pixel driving circuit D2, and so on. The first pixel driving circuit D1 and the second pixel driving circuit D2 are connected to the voltage signal line with the same voltage, specifically, the first pixel driving circuit D1 and the second pixel driving circuit D2 are connected to the voltage signal line with the same VDD signal, so that the voltages of the driving circuits of the first display area AA1 and the second display area AA2 are the same, and the brightness uniformity of the display panel in the first display area AA1 and the second display area AA2 is improved. For example, as shown in fig. 2, two capacitive metal layers C form a capacitance. Alternatively, the first pixel driving circuit D1 may be disposed in the first display area AA1 to reduce the routing distance, that is, in a form that the driving circuit is disposed in the first display area AA1, or the first pixel driving circuit D1 may be disposed in the second display area AA2, that is, in a form that the driving circuit is disposed externally with respect to the first display area AA1, so as to further improve the light transmittance of the first display area AA 1.
Optionally, when the light emitting unit adopts the top light emitting structure, since the first trace 4 adopts the transparent trace, light cannot be reflected, and light needs to be reflected by the opaque first electrode block 3 to achieve normal emergent light, but the size of the first display area AA1 is limited, so that in order to facilitate arrangement of the first electrode block 3, in some alternative embodiments, the orthographic projection area of the first electrode block 3 on the substrate 1 is smaller than the orthographic projection area of the second electrode block 6 on the substrate 1.
It will be appreciated that by reducing the size of the first electrode block 3, the use of a small anode facilitates the layered arrangement of the first electrode block 3 in the first display area AA1 while ensuring the display effect of the first display area AA 1.
In some alternative embodiments, the display device further includes a second trace 5, where the second trace 5 is electrically connected to the first trace 4, and the first trace 4 and the second trace 5 that are electrically connected to each other are arranged in layers, and the first display area AA1 includes an optical element reserved area TA for setting an optical element, and each of the first trace 4 and the second trace 5 located in the first display area AA1 are respectively arranged around the optical element reserved area TA. In order to avoid influencing the light entering quantity of the optical element, each first trace 4 and the second trace 5 located in the first display area AA1 are arranged to avoid the reserved area TA of the optical element, specifically, when the reserved area TA of the optical element is circular, each first trace 4 and the second trace 5 located in the first display area AA1 are respectively arranged to surround the reserved area TA of the optical element in a circular shape, so as to ensure that the optical element has enough light entering quantity.
Optionally, the second trace 5 is a non-transparent trace, and it should be noted that, the second traces 5 of the first display area AA1 and the second display area AA2 all use the same non-transparent trace, so as to reduce a film layer structural difference between the first display area AA1 and the second display area AA2, and further reduce a brightness difference between the first display area AA1 and the second display area AA2, and specifically, the second trace 5 may use metals such as aluminum, titanium, aluminum titanium, silver, molybdenum, and the like.
In some alternative embodiments, the orthographic projections of the second traces 5 located in different layers on the substrate 1 are not overlapped, so as to avoid signal interference generated by the second traces 5 between adjacent layers, and ensure display stability.
In some alternative embodiments, the first electrode block 3 comprises at least one layer of metal, such as a metal material with low resistivity and good electrical conductivity, e.g. silver, molybdenum, etc.; specifically, the first electrode block 3 includes indium tin oxide, aluminum, and indium tin oxide composite material layers that are stacked.
The embodiment of the invention also provides a display device, which comprises: and a display panel, wherein the display panel is the display panel in any embodiment. The display device further includes an optical element disposed corresponding to the first display area AA1 of the display panel. The optical element may be an image acquisition device for acquiring external image information. In this embodiment, the optical element is a complementary metal oxide semiconductor (Complementary Metal Oxide Semiconductor, CMOS) image capturing device, and in other embodiments, the optical element may be another type of image capturing device such as a Charge-coupled device (CCD) image capturing device. It will be appreciated that the optical element may not be limited to an image capture device, for example, in some embodiments, the optical element may also be an optical sensor such as an infrared sensor, a proximity sensor, an infrared lens, a floodlight sensing element, an ambient light sensor, and a dot matrix projector. In addition, the display device may further integrate other components, such as an earpiece, a speaker, etc., on the second surface S2 of the display panel 100.
