The OLED has attracted broad attention from industry as an active light-emitting element and the light extraction efficiency thereof is an important factor impacting the OLED. As illustrated by
In the related art, in order to improve the light extraction efficiency of the OLED, a metallic reflection face is formed on an opening side wall of the pixel defining layer, i.e., a side thereof for arranging the light-emitting layer. However, a process of forming the metallic reflection face is complicated. For example, the pixel defining layer shall cover a part of the anode while the metallic reflection face shall not touch the anode. On the other hand, surface curvature of the metallic reflection face is limited, leading to a still limited light extraction efficiency of the element. For example, reflected light tends to be quenched on the surface of the metallic reflection face.
An embodiment of this disclosure provides an array substrate applicable to a bottom-emitting OLED display panel, a top-emitting OLED display panel, and a bidirectional OLED display panel. As illustrated by
In the array substrate according to the embodiment of this disclosure, the first metallic nanoparticle layers configured to reflect the light exiting the electroluminescent function layers are arranged on the side walls of the blocking walls of the pixel defining layer 20, so that light rays incident on the pixel defining layer 20 in a traverse or oblique direction can be reflected back to and propagated out of the pixel areas, thus improving the light extraction efficiency of the array substrate.
It shall be noted that the first metallic nanoparticles in the first metallic nanoparticle layer refer to nanoscale particles having a surface with a reflection property. The shape of a first metallic nanoparticle can be a sphere, a quasi-sphere, a nano-size rod, a nano-size sheet, and etc., although the embodiment of this disclosure is limited thereto. Furthermore, as illustrated by
According to some implementation modes of the embodiment of the disclosure, sizes of each of the metallic reflection spherical nanoparticles are between 10 nm and 20 nm, for example, so that a process of forming the spherical particles can be simplified, but also a better effect of reflecting the light can be achieved. For example, the sizes of the metallic reflection spherical nanoparticles can be 10 nm, 15 nm, or 20 nm. Of course, in a real application, the sizes of the metallic reflection spherical nanoparticles can be determined according to a real application environment, although the embodiment of this disclosure is not limited thereto.
In some implementation modes, the electroluminescent function layer can include electroluminescent function layers. According to some implementation modes of the embodiment of this disclosure, the array substrate can further include first electrodes 50 located between the electroluminescent function layers 30 and the underlying substrate 10, and second electrodes 60 located on sides of the electroluminescent function layers 30 away from the underlying substrate 10 so that elements in the pixel areas can be OLED elements. Furthermore, an important factor hindering the development of an OLED element is the service life thereof, which is determined by density of a current driving the OLED to emit light. If brightness of light emitted by the OLED is fixed, then the service life thereof can be extended by enhancing the light extraction efficiency thereof, and lowering the current density thereof. According to the embodiment of this disclosure, the first metallic nanoparticle layers are arranged on the side walls of the blocking walls of the pixel defining layer 20 so that the light rays incident on the pixel defining layer 20 in a traverse or oblique direction can be reflected back to and exit the pixel area, thus improving the light extraction efficiency of the OLED elements, so the driving current can be lowered for the same brightness to lower power consumption, and extend the service life of the OLED elements. It shall be noted that a pixel circuit configured to drive the electroluminescent function layers to emit light is formed on the underlying substrate according to some implementation modes of the embodiment of this disclosure, where the pixel circuit includes an array of thin film transistors (TFTs).

In generally, the electron injection layers, the electron transport layers, the hole transport layers, and the hole injection layers are formed to cover the entire underlying substrate, so the first metallic nanoparticle layers and the second electrodes 60 do not touch. Furthermore, the first metallic nanoparticle layers can be arranged on parts of the side walls of the blocking walls of the pixel defining layers which are between the electroluminescent material layers and the blocking walls of the pixel defining layers.

All other components indispensable to the display device shall readily occur to those ordinarily skilled, so a repeated description thereof is omitted herein, and the embodiment of this disclosure is not limited thereto.
Based upon the same inventive conception, an embodiment of this disclosure further provides a method for fabricating an array substrate. As illustrated by
The operation S501 is: forming a pixel defining layer on one side of an underlying substrate, where the pixel defining layer includes a plurality of blocking walls arranged at intervals.
The operation S502 is: forming first metallic nanoparticle layers on side walls of the blocking walls.
The operation S503 is: forming electroluminescent function layers each located between two adjacent blocking walls of the plurality of blocking walls, where the first metallic nanoparticle layers are located on the side walls of the plurality of blocking walls proximate to the electroluminescent function layers, and are configured to reflect light exiting the electroluminescent function layers.
First metallic nanoparticles in the first metallic nanoparticle layer refer to nanoscale particles having a surface with a reflection property. The shape of a first metallic nanoparticle can be a sphere, a quasi-sphere, a nano-size rod, a nano-size sheet, and etc., although the embodiment of this disclosure is limited thereto. Furthermore, as illustrated by
According to some implementation modes of the embodiment of the disclosure, sizes of each of the metallic reflection spherical nanoparticles are between 10 nm and 20 nm, for example, so that a process of forming the spherical particles can be simplified, but also a better effect of reflecting the light can be achieved. For example, the sizes of the metallic reflection spherical nanoparticles can be 10 nm, 15 nm, or 20 nm. Of course, in a real application, the sizes of the metallic reflection spherical nanoparticles can be determined according to a real application environment, although the embodiment of this disclosure is not limited thereto.
In the method for fabricating the array substrate according to the embodiment of this disclosure, the first metallic nanoparticle layers able to reflect the light emitted from the electroluminescent function layers are formed on the side walls of the blocking walls of the pixel defining layer 20, so that light rays incident on the pixel defining layer 20 in a traverse or oblique direction can be reflected back to and propagated out of pixel areas, thus improving the light extraction efficiency of OLED elements in the array substrate. Accordingly, the driving current at the same brightness can be lowered to lower power consumption and extend the service life of the OLED elements.
According to some implementation modes of this embodiment, before the pixel defining layer including a plurality of openings is formed on one side of the underlying substrate, the method can further include forming first electrodes on the underlying substrate; and after the electroluminescent function layers are formed in the openings, the method can further include forming second electrodes on the underlying substrate formed with the electroluminescent function layers. According to some implementation modes of the embodiment, transparent electrically-conductive layers can be formed on the underlying substrate as the first electrodes, and reflection electrically-conductive layers can be formed on the underlying substrate formed with the electroluminescent function layers as the second electrodes. Accordingly, a bottom-emitting OLED array substrate is formed. Or, reflection electrically-conductive layers can be formed on the underlying substrate as the first electrodes, and transparent electrically-conductive layers can be formed on the underlying substrate formed with the electroluminescent function layers as the second electrodes. Accordingly a top-emitting OLED array substrate is formed.
According to some implementation modes of this embodiment, the first metallic nanoparticle layers can be formed on the side walls of the blocking walls by printing solution including the first metallic nanoparticles on the side walls of the blocking walls using an inkjet printing process to form the first metallic nanoparticle layers. For example, the material of the first metallic nanoparticle layers is metallic reflection spherical nanoparticles, and the metallic reflection spherical nanoparticles on the surfaces of the side walls of the blocking walls 21 of the pixel defining layer 20 facing the electroluminescent function layers 30 can be formed by forming the pixel defining layer 20 for filling the electroluminescent function layers 30 on the underlying substrate 10, and printing solution including metallic reflection spherical nanoparticles on the surfaces of the side walls of the blocking walls 21 of the pixel defining layer 20 facing the electroluminescent function layers 30 using an inkjet printing process. Then the metallic reflection spherical nanoparticles are distributed on the surfaces of the side walls of the blocking walls 21 of the pixel defining layer 20. The metallic reflection spherical nanoparticles formed by printing the solution can be the same as the metallic reflection spherical nanoparticles in the solution, or can be metallic reflection spherical nanoparticles obtained by treating the metallic reflection spherical nanoparticles in the solution, thus having a different size or a different shape from the original metallic reflection spherical nanoparticles.
According to some other implementation modes of this embodiment, the first metallic nanoparticle layers can be formed using a self-assembling method. The first metallic nanoparticle layers can be formed on the side walls of the blocking walls by immersing the blocking walls of the pixel defining layer into solution comprising first metallic nanoparticles to form the first metallic nanoparticle layers, where the blocking walls are upside down, i.e., the blocking walls are under the underlying substrate, when they are immersed into the solution. For example, the material of the first metallic nanoparticle layers is metallic reflection spherical nanoparticles. The metallic reflection spherical nanoparticles on the surfaces of the side walls of the blocking walls 21 of the pixel defining layer 20 facing the electroluminescent function layers 30 can be formed by forming the pixel defining layer 20 for filling the electroluminescent function layers 30 on the underlying substrate 10, turning the underlying substrate formed with the pixel defining layer 20 upside down, and immersing the upside down underlying substrate into solution including the metallic reflection spherical nanoparticles. Then the metallic reflection spherical nanoparticles are distributed on the surfaces of the side walls of the blocking walls 21 of the pixel defining layer 20. In the case of the top-emitting OLED display panel, the underlying substrate formed with the pixel defining layer 20 can be immersed into the solution including the metallic reflection spherical nanoparticles. In the case of the bottom-emitting OLED display panel, light shall be transmitted outwards through the first electrodes, so the first electrodes shall not be immersed into or contact the solution when the underlying substrate is upside down, and only the blocking walls 21 of the pixel defining layer 20 are turned upside down, and immersed into the solution including the metallic reflection spherical nanoparticles. Furthermore, for each of the blocking walls, a depth of a part of the blocking wall which is immersed into the solution is shallower than a depth of the blocking walls, so that the solution and the first electrodes do not touch.
According to still some other implementation modes of this embodiment, the first metallic nanoparticle layers can alternatively be formed through exposure. Forming the pixel defining layer on one side of the underlying substrate, and forming the first metallic nanoparticle layers on the side walls of the blocking walls by: forming a pixel defining layer film doped with the first metallic nanoparticles on the underlying substrate; and after the pixel defining layer film is exposed and developed, forming the pixel defining layer comprising the plurality of blocking walls arranged at intervals, and forming the first metallic nanoparticle layers on the side walls of the blocking walls. For example, the material of the first metallic nanoparticle layers is metallic reflection spherical nanoparticles. The metallic reflection spherical nanoparticles on the side walls of the blocking walls 21 can be formed by forming the pixel defining layer film doped with metallic reflection spherical nanoparticles on the underlying substrate 10, and exposing and developing the pixel defining layer film to form the pixel defining layer 20 having metallic reflection spherical nanoparticles above its surface so that the metallic reflection spherical nanoparticles are formed on the side walls of the blocking walls 21 of the pixel defining layer 20, and the metallic reflection spherical nanoparticles are structured integral to the pixel defining layer 20.
As can be apparent from the implementation modes above, the method for fabricating the OLED array substrate according to the embodiment of this disclosure can form the metallic reflection spherical nanoparticles in a simple and feasible process to significantly improve the light extraction efficiency of the OLED elements.
According to some implementation modes of the embodiment of the disclosure, such as what is illustrated by
According to some implementation modes of the embodiment of the disclosure, such as what is illustrated by
According to another implementation mode of the embodiment of this disclosure, before the pixel defining layer 20 is formed, and the first electrodes are formed on the underlying substrate 10. Then the pixel defining layer 20 including the blocking walls is formed, after which the underlying substrate 10 including the first electrodes and the pixel defining layer 20 is immersed into solution including metallic reflection spherical nanoparticles to form the metallic reflection spherical nanoparticles on the sides of the first electrodes away from the underlying substrate, and to form the metallic reflection spherical nanoparticles on the side walls of the blocking walls 21 of the pixel defining layer 20. In this way, the treatment processes can be further simplified to lower the cost.
Since the metallic reflection spherical nanoparticles are formed on the surfaces of the first electrodes 50, the light in the top-emitting OLED display panel can be significantly alleviated from being quenched, to further improve the light out-coupling efficiency of the OLED elements. It shall be noted that the second metallic nanoparticle layers can be formed similarly to the first metallic nanoparticle layers, so a repeated description thereof is omitted herein.
