In some embodiments, the electronic device may be provided with a first display area, and the optical element is disposed on the back of the light-transmissive first display area, so as to implement full-screen display of the electronic device under the condition that the optical element is ensured to work normally.
However, the current display panel structure is limited, and the display difference exists between the first display area and the second display area, which affects the user experience.
In order to solve the above problems, embodiments of the present invention provide a display panel and a display device, and the following describes embodiments of the display panel and the display device 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 flat display panel (Micro-OLED or Micro-LED), and the like. The description will be given taking the display panel as an OLED display panel as an example.
Referring to fig. 1 to 4, an embodiment of the 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 including: a substrate 1; the pixel definition layer 2 is arranged on one side of the substrate 1, and the pixel definition layer 2 comprises a plurality of pixel openings; and the electrode layer is at least partially arranged in the pixel opening and comprises a plurality of first electrode blocks 3 arranged in the first display area AA1, the first electrode blocks 3 are arranged in layers in the direction perpendicular to the plane of the substrate 1, and orthographic projections of the first electrode blocks 3 on the substrate 1 are not overlapped.
The display panel provided by the embodiment of the invention comprises a substrate 1, a pixel defining layer 2 and an electrode layer, wherein the electrode layer comprises first electrode blocks 3, and each first electrode block 3 is arranged in a layered manner in a direction perpendicular to the plane of the substrate 1, that is, each first electrode block 3 is respectively arranged at different height positions of the pixel defining layer 2, so as to avoid mutual interference of the first electrode blocks 3 between each layer, and compared with the case that each first electrode block 3 is arranged at the same layer, each first electrode block 3 is arranged in the same layer in a layered manner, so that more routing spaces can be reserved, 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 between 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 in the embodiment of the present invention may specifically be an anode layer and/or a cathode layer, when the electrode layer is the anode layer, each anode block is arranged in a layered manner, and the corresponding cathode layer may be arranged in a layered manner corresponding to each anode block, or may be arranged on the whole surface, so as to ensure the display effect. Similarly, when the electrode layer is a cathode layer, each cathode block is arranged in a layer, and the corresponding anode blocks can be arranged in a layer or in the same layer, without any special limitation. Fig. 2 to 4 illustrate the electrode layer as an anode layer in the embodiments of the present invention.
It can be understood that the orthographic projections of the first electrode blocks 3 on the substrate 1 are set to be not coincident, so as to avoid that the first electrode blocks 3 located on different layers are shielded, and the normal light-emitting efficiency of the display panel is affected, for example, the first electrode blocks 3 located on an upper layer may shield the first electrode blocks 3 located on a lower layer, and the light-emitting of the organic light-emitting layers corresponding to the first electrode blocks 3 is affected.
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 implement light emitting display of the display panel. In the related art, due to the small area size of the first display area AA1, 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 less than that of the anode blocks in the second display area AA2, so that the first display area AA1 and the second display area AA2 have a relatively obvious display difference when the display panel is displaying. In order to solve the problem, in the display panel provided in the embodiment of the invention, the first electrode blocks 3 in the first display area AA1 are arranged in layers in a direction perpendicular to the plane of the substrate 1, so that the first electrode blocks 3 located in different layers can be routed by using the space of each layer, the number of the first electrode blocks 3 that can be arranged in the first display area AA1 is increased, the pixel density of the first display area AA1 is further increased, 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 the first electrode blocks 3 are arranged in a layered manner in the direction perpendicular to the plane of the substrate 1, that is, when the light-emitting units corresponding to the first electrode blocks 3 emit light at different gradients, the light can be compensated at different angles by using the optical gradient principle, so that the sensitivity of the camera in the first display area AA1 to 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, and the light transmittance of the first display area AA1 is greater than that 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 AA2 on the circumferential side.
Alternatively, 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%, or even higher, the light transmittance of each functional film layer of the display panel in this embodiment is greater than 80%, and even at least some of the functional film layers are 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 disposing optical elements such as a camera and a fingerprint recognition element, and specifically, the first display area AA1 includes an optical element reserved area TA for disposing optical elements, and the first electrode blocks 3 located in different layers may be annularly distributed to surround the optical element reserved area TA, so as to avoid the light entering amount of the optical elements and ensure the normal operation of the optical elements, and in order to ensure the uniformity of light emission of the light emitting units corresponding to the first electrode blocks 3 located in different layers, the first electrode blocks 3 located in different layers are concentrically distributed, so as to improve the uniformity of light emission.
In order to send a driving signal to each first electrode block 3, in some optional embodiments, the display panel further includes first wirings 4, each first wiring 4 is disposed on the same layer as each first electrode block 3 correspondingly connected to the first wiring 4, and the first wirings 4 are transparent wirings.
It should be noted that, since the optical element needs to be correspondingly disposed in the first display area AA1, 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), polyethylenedioxythiophene-polystyrenesulfonic acid PEDOT: PSS, graphene, and carbon nanotubes. When the material of the first trace 4 includes at least one of the above materials, it is able to ensure that the first trace 4 has a high light transmittance, and also enable the first trace 4 to be conductive.
In order to minimize the influence of the first tracks 4 on the light transmittance, in some alternative embodiments, orthographic projections of the first tracks 4 on the substrate 1 at different layers are at least partially overlapped.
It can be understood that the orthographic projections of the first wires 4 on the substrate 1 at least partially coincide, that is, the first wires 4 coinciding in the orthographic projections can affect the light output of the same area, but do not affect the light output of a plurality of different areas, so that the shielding area of the first wires 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 includes an array layer disposed between the substrate 1 and the pixel defining layer 2, the array layer including a second pixel driving circuit D2 and a first pixel driving circuit D1; the electrode layer further comprises a second electrode block 6 arranged in the second display area AA2, the first electrode block 3 is electrically connected with the first pixel driving circuit D1, the second electrode block 6 is electrically connected with 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 abundant wiring space in the second display area AA2, the second pixel driving circuit D2 usually employs a 7T1C circuit, while the wiring space in the first display area AA1 is tight, and a 1T1C circuit may be employed, where "1T 1C 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 the other "7T 1C circuit", "7T 2C circuit", "9T 1C circuit", and so on. The first pixel driving circuit D1 and the second pixel driving circuit D2 are connected to voltage signal lines with the same voltage, specifically, the first pixel driving circuit D1 and the second pixel driving circuit D2 are connected to voltage signal lines with the same VDD signal, so that the driving circuit voltages 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 capacitor metal layers C form a capacitor. Optionally, the first pixel driving circuit D1 may be disposed in the first display area AA1 to reduce the routing distance, that is, the driving circuit is disposed in the first display area AA1, or the first pixel driving circuit D1 may also be disposed in the second display area AA2, that is, 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 a top light emitting structure, since the first wire 4 adopts a transparent wire, light cannot be reflected, and light needs to be reflected by the opaque first electrode block 3 to realize normal outgoing of light, but limited by the size of the first display area AA1, in order to facilitate arrangement of the first electrode block 3, in some optional 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 can be understood that the small anode can be used to facilitate the layering of the first electrode blocks 3 in the first display area AA1 by reducing the size of the first electrode blocks 3, and at the same time, the display effect of the first display area AA1 can be ensured.
In some optional embodiments, the optical device further includes a second trace 5, the second trace 5 is electrically connected to the first trace 4 respectively, and the first trace 4 and the second trace 5 electrically connected to each other are disposed in a layered manner, the first display area AA1 includes an optical element reserved area TA for disposing an optical element, and each of the first trace 4 and the second trace 5 located in the first display area AA1 are disposed around the optical element reserved area TA respectively.
