Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
Currently, the OLED display device has a problem of abnormal display due to a failure of the package during the production or after being used by a user for a certain period of time. That is to say, the encapsulation effect of the thin film encapsulation layer of the OLED display device does not achieve the expected encapsulation effect, so that water vapor, oxygen, and the like enter the organic light emitting device layer of the OLED display device, and the display function of the organic light emitting device layer is abnormal.
After research, bubbles appear between two adjacent film layers in a film packaging layer of the OLED display device, and the probability of water vapor, oxygen and the like entering an organic light-emitting device layer is increased due to the existence of the bubbles, so that the display function of the organic light-emitting device layer is abnormal. In addition, when the OLED display device has a flexible function, the action of a user bending the flexible display device may squeeze bubbles between the film layers, thereby causing expansion of the bubbles, and further causing a peeling (peeling) area between the film layers, that is, further increasing the probability of water vapor, oxygen, and the like entering the organic light emitting device layer.
Therefore, if the probability of generating bubbles between the film layers can be reduced, the problem of package failure of the OLED display device can be effectively solved.
Fig. 1 is a schematic structural diagram of a display panel 1 according to an embodiment of the present application. Fig. 2 is a schematic structural diagram of a display device according to an embodiment of the present application.
Based on this, embodiments of the present application provide a display panel 1. As shown in fig. 1, the display panel 1 may include an organic light emitting device layer 11 and a thin film encapsulation layer 12 that are stacked. The thin film encapsulation layer 12 is disposed on one side of the organic light emitting device layer 11, and includes a first inorganic sublayer 122 and a first water and oxygen consuming sublayer 121 that are disposed in a stacked manner. The first water-oxygen consuming sublayer 121 is disposed on a side of the first inorganic sublayer 122 away from the organic light-emitting device layer 11, and the first water-oxygen consuming sublayer 121 may be used to block ammonia gas or ammonia derivatives from diffusing towards the thin film encapsulation layer 12.
Specifically, the organic light emitting device layer 11 may be a film layer having an organic light emitting diode. A thin film encapsulation layer 12(TFE) may be disposed on the organic light emitting device layer 11. The thin film encapsulation layer 12 may block moisture, oxygen, and the like from entering the organic light emitting device layer 11, thereby reducing the influence of the moisture, oxygen, and the like on the organic light emitting device layer 11.
In order to be able to block moisture, oxygen, and the like, the related art thin film encapsulation layer generally includes an inorganic film layer in order to ensure the moisture, oxygen, and the like blocking performance of the thin film encapsulation layer. For the sake of convenience of distinction from the inorganic film layer hereinafter, the inorganic film layer may be referred to as a first inorganic film layer. However, the thickness of the first inorganic film layer cannot ensure the flexible property of the prior art thin film encapsulation layer. That is, when the film encapsulation layer of the prior art is applied to the flexible display panel, the first inorganic film layer may be broken when the film encapsulation layer is bent. Therefore, in order to avoid the fracture of the first inorganic film layer during the bending process, the thickness of the first inorganic film layer needs to be smaller than the limit thickness at the time of fracture. That is, the thickness of the first inorganic film layer needs to be reduced. In other words, the smaller the thickness of the first inorganic film layer, the better the flexibility of the thin film encapsulation layer. However, the reduction in the thickness of the first inorganic film layer brings about a reduction in the flexibility of the thin film encapsulation layer, and also brings about a reduction in the performance of the thin film encapsulation layer to block moisture, oxygen, and the like.
Therefore, in the case where the thickness of the first inorganic film layer is reduced, in order to maintain the performance of the thin film encapsulation layer for blocking moisture, oxygen, and the like, the first water and oxygen consuming sublayer 121 is introduced into the thin film encapsulation layer, that is, the thin film encapsulation layer 12 shown in fig. 1 is formed. Here, the first water oxygen consuming sublayer 121 may consume moisture, oxygen, and the like. In other words, the first water oxygen consuming sublayer 121 may react with water vapor, oxygen, and the like, thereby preventing the water vapor, oxygen, and the like from penetrating through the thin film encapsulation layer 12 to reach the organic light emitting device layer 11. In the present embodiment, the first water oxygen consuming sublayer 121 may include at least one of aluminum, magnesium, zinc, nickel, tin, lead, and the like. The metal elements can not only consume water vapor, oxygen and the like, but also form a compact oxidation film, thereby effectively reducing the transmittance of the water vapor, the oxygen and the like and further playing a role in blocking the water vapor, the oxygen and the like.
For example, in one embodiment of the present application, the first water oxygen consuming sublayer 121 may include aluminum.
Specifically, after the aluminum and the oxygen are subjected to an oxidation reaction, a dense aluminum oxide thin film may be formed on the surface of the first water oxygen consuming sublayer 121. The compact alumina film can prevent water vapor, oxygen and the like from diffusing into the first water-oxygen consumption sublayer 121, and also prevent water vapor, oxygen and the like from diffusing into the film packaging layer 12, so that the probability that the water vapor, the oxygen and the like reach the organic light-emitting device layer 11 is effectively reduced.
In addition, the aluminum has good ductility, so that the first water and oxygen consuming sublayer 121 ensures the flexibility of the thin film encapsulation layer 12 and the flexibility of the display panel 1 while ensuring the performance of the thin film encapsulation layer 12 for blocking water vapor, oxygen and the like. That is, the bending resistance of the display panel 1 is ensured.
Further, since the absorption spectrum of alumina produced by the oxidation reaction of aluminum and oxygen is in the ultraviolet region, the transmittance of display light generated in the organic light-emitting device layer 11 is not reduced.
In addition, for convenience of description, the first inorganic film layer having a reduced thickness may be referred to as a first inorganic sublayer 122. Here, the first water oxygen consuming sublayer 121 may be disposed on a side of the first inorganic sublayer 122 away from the organic light emitting device layer 11. That is, for the display device as shown in fig. 2, the first water oxygen consuming sublayer 121 may be disposed close to the touch panel 2. For example, the touch panel 2 may be directly disposed on the first water oxygen consuming sublayer 121.
Specifically, as shown in fig. 2, the display device may include a stacked display panel 1 and a touch panel 2, and the touch panel 2 may be disposed on a display light emission side of the display panel 1. In this case, the thin film encapsulation layer 12 may be disposed between the touch panel 2 and the organic light emitting device layer 11. Accordingly, the first water and oxygen consuming sublayer 121 may be closer to the touch panel 2 than the first inorganic sublayer 122.
In the process of manufacturing the touch panel 2, the inorganic layer 21 is prepared. When the inorganic layer 21 of the touch panel 2 includes at least one of silicon nitride, silicon oxynitride, and the like, ammonia gas or an ammonia derivative is generated in the preparation process of the inorganic layer 21 of the touch panel 2, thereby causing the ammonia gas or the ammonia derivative to remain in the touch panel 2. Here, the derivatives of ammonia may be meant to include ammonium (NH) groups4 +) And under certain conditions, the ammonia derivative can decompose ammonia gas.
Through research, ammonia is included in bubbles between film layers of the film packaging layer. It can be seen that, in the display panel of the prior art, the ammonia gas or the ammonia derivative remaining in the touch panel 2 may diffuse into the film encapsulation layer of the display panel through the inorganic layer 21, and may be accumulated between two adjacent film layers of the film encapsulation layer, thereby causing the generation of bubbles.
Since ammonia gas or ammonia derivatives can diffuse through the inorganic layer 21 of the touch panel 2, when the first inorganic sublayer 122 and the inorganic layer 21 of the touch panel 2 are prepared in the same manner, i.e., when the first inorganic sublayer 122 includes at least one of silicon nitride, silicon oxynitride, and the like, ammonia gas or ammonia derivatives diffusing from the touch panel 2 can permeate through the first inorganic sublayer 122. Therefore, in order to prevent ammonia gas or ammonia derivatives from permeating through the first inorganic sublayer 122, the first water oxygen consuming sublayer 121 may be disposed on a side of the first inorganic sublayer 122 close to the touch panel 2.
As shown in fig. 2, when the first water and oxygen consuming sublayer 121 is disposed on one side of the first inorganic sublayer 122 close to the touch panel 2, the dense oxide films on the surfaces of the first water and oxygen consuming sublayer 121 and the first water and oxygen consuming sublayer 121 can block ammonia gas or ammonia derivatives from diffusing into the first water and oxygen consuming sublayer 121, and also block ammonia gas or ammonia derivatives from diffusing into the thin film encapsulation layer 12, so as to effectively reduce the probability of generating bubbles between the film layers of the thin film encapsulation layer 12, and further effectively improve the problem of encapsulation failure of the OLED display device.
In the embodiment of the application, the first water and oxygen consuming sublayer 121 is disposed on the side of the first inorganic sublayer 122 away from the organic light emitting device layer 11, that is, compared with other film layers of the thin film encapsulation layer 12, the first water and oxygen consuming sublayer 121 is disposed at the position closest to the touch panel 2, so that the dense oxide films on the surfaces of the first water and oxygen consuming sublayer 121 and the first water and oxygen consuming sublayer 121 can block the ammonia gas or the derivative of ammonia from diffusing into the first water and oxygen consuming sublayer 121, that is, block the ammonia gas or the derivative of ammonia from diffusing into the thin film encapsulation layer 12, thereby effectively reducing the probability of generating bubbles between the film layers of the thin film encapsulation layer 12, and further effectively improving the problem of encapsulation failure of the OLED display device.
In one embodiment of the present application, the sum of the thicknesses of the first inorganic sublayer 122 and the first water oxygen consuming sublayer 121 may be 1 micron or less. Specifically, in one embodiment of the present application, the thickness of the first water oxygen consuming sublayer 121 may be 200 nm or more and 300 nm or less.
Here, the first inorganic sublayer 122 and the first water oxygen consuming sublayer 121 may be the first inorganic film layer of the improved thin film encapsulation layer of the related art. Specifically, since the thickness of the first inorganic film layer of the related art thin film encapsulation layer is about 1 μm, the thicknesses of the first inorganic sublayer 122 and the first water oxygen consuming sublayer 121 are equivalent to the thickness of the first inorganic film layer. That is, replacing the first inorganic film layer of the thin film encapsulation layer of the prior art with the first inorganic sublayer 122 and the first water and oxygen consuming sublayer 121 does not cause the problem of increasing the thickness of the thin film encapsulation layer. In other words, the first inorganic sublayer 122 and the first water oxygen consuming sublayer 121 are not disposed to be disadvantageous to the over-thinning of the display panel.
In addition, the moisture, oxygen, and the like blocking effects of the first inorganic sublayer 122 and the first water and oxygen consuming sublayer 121 may be equivalent to or better than those of the first inorganic film layer of the film encapsulation layer of the related art. That is, replacing the first inorganic film layer of the film encapsulation layer of the prior art with the first inorganic sublayer 122 and the first water and oxygen consuming sublayer 121 does not bring about the problem of the film encapsulation layer that the effect of blocking water vapor, oxygen, and the like is reduced.

In one embodiment of the present application, the thin film encapsulation layer 12 may further include a second water oxygen consuming sublayer 125. The second water-oxygen consuming sublayer 125 is disposed on a side of the first inorganic sublayer 122 adjacent to the organic light-emitting device layer 11.
Specifically, the second water oxygen consuming sublayer 125 may be disposed between the first inorganic sublayer 122 and the organic light emitting device layer 11. For example, in one embodiment of the present application, as shown in fig. 3, the second water oxygen consuming sublayer 125 may be disposed directly on the organic light emitting device layer 11. In such a case, the thin film encapsulation layer 12 may include only the first water oxygen consuming sublayer 121, the first inorganic sublayer 122, and the second water oxygen consuming sublayer 125.
Specifically, the first water-oxygen consuming sublayer 121, the first inorganic sublayer 122, and the second water-oxygen consuming sublayer 125 may all function to prevent water vapor, oxygen, and the like from entering the organic light emitting device layer 11, and the effect of preventing water vapor, oxygen, and the like may be equivalent to or better than that of the film encapsulation layer of the prior art, thereby ensuring the performance of the film encapsulation layer 12 to block water vapor, oxygen, and the like. When the first water oxygen consuming sublayer 121 and the second water oxygen consuming sublayer 125 are made of metal, the flexibility of the thin film encapsulation layer 12 can be ensured by the extension characteristics of the first water oxygen consuming sublayer 121 and the second water oxygen consuming sublayer 125.
Compared with the prior art, the thickness of the thin film encapsulation layer 12 shown in fig. 3 can be effectively reduced, thereby facilitating the ultra-thinning of the display panel 1.
Specifically, the film encapsulation layer of the related art includes a first inorganic film layer, an organic film layer, and a second inorganic film layer, which are sequentially stacked. Under the same encapsulation effect, the thicknesses of the first water oxygen consuming sublayer 121 and the first inorganic sublayer 122 may be smaller than the thicknesses of the first inorganic film layer, and the thickness of the second water oxygen consuming sublayer 125 may be smaller than the thicknesses of the organic film layer and the second inorganic film layer, so that the thickness of the thin film encapsulation layer 12 shown in fig. 3 is much smaller than the thickness of the thin film encapsulation layer in the prior art, thereby effectively reducing the thickness of the display panel 1.
In another embodiment of the present application, as shown in fig. 4, the thin film encapsulation layer 12 may further include an organic sublayer 123 and a second inorganic sublayer 124 disposed between the first inorganic sublayer 122 and the second water oxygen consuming sublayer 125. The organic sublayer 123 is disposed on a side of the first inorganic sublayer 122 remote from the first water oxygen consuming sublayer 121, and the second inorganic sublayer 124 is disposed between the organic sublayer 123 and the second water oxygen consuming sublayer 125.
Specifically, for the display panel 1 which does not pursue the ultra-thinning, a structure of the thin film encapsulation layer 12 as shown in fig. 4 may be employed. Here, the thickness of the first water oxygen consuming sublayer 121 and the first inorganic sublayer 122 may be equal to that of the first inorganic film layer, the thickness of the second water oxygen consuming sublayer 125 and the second inorganic sublayer 124 may be equal to that of the second inorganic film layer, and the thickness of the organic sublayer 123 may be equal to that of the organic film layer, compared to the related art thin film encapsulation layer, so that the thickness of the thin film encapsulation layer 12 as shown in fig. 4 may be equal to that of the related art thin film encapsulation layer. The first water and oxygen consuming sublayer 121 can compensate for the performance of the first inorganic sublayer 122 that is lost due to the reduction of the thickness of the first inorganic film layer, such as water vapor and oxygen blocking. Similarly, the second water and oxygen consuming sublayer 125 can compensate for the performance of the second inorganic sublayer 124 that is lost due to the reduced thickness of the second inorganic film layer to block moisture, oxygen, and the like.
Alternatively, in another embodiment of the present application, the second water oxygen consuming sublayer 125 may be disposed between the organic sublayer 123 and the second inorganic sublayer 124.
In the embodiment of the present application, the second water oxygen consuming sublayer 125 and the first water oxygen consuming sublayer 121 are functionally opposite. The material used for the second water oxygen consuming sublayer 125 may be the same as that used for the first water oxygen consuming sublayer 121, or may be different from that used for the first water oxygen consuming sublayer 121, and the embodiment of the present application does not limit the material used for the second water oxygen consuming sublayer 125.
In one embodiment of the present application, as shown in fig. 4, the sum of the thicknesses of the second inorganic sublayer 124 and the second water oxygen consuming sublayer 125 may be 1 micron or less. Specifically, in one embodiment of the present application, the thickness of the first water oxygen consuming sublayer 121 may be 200 nm or more and 300 nm or less.
In the embodiment of the present application, the first water oxygen consuming sublayer 121 may be prepared by atomic layer deposition or sputtering. Similarly, the second water-oxygen consuming sublayer 125 can also be prepared by atomic layer deposition or sputtering.
The display panel 1 according to the embodiment of the present application is described above, and the display device according to the embodiment of the present application is described below with reference to fig. 2.
As shown in fig. 2, the display device may include the display panel 1 described in any of the embodiments of the display panel 1, and a touch panel 2 stacked on the display panel 1.

Specifically, in the touch panel 2, the number of the inorganic layers 21 may be one or more, and the number of the inorganic layers 21 of the touch panel 2 is not limited in the embodiments of the present application.
In the embodiment of the application, the first water and oxygen consuming sublayer 121 is disposed on the side of the first inorganic sublayer 122 away from the organic light emitting device layer 11, that is, compared with other film layers of the thin film encapsulation layer 12, the first water and oxygen consuming sublayer 121 is disposed at the position closest to the touch panel 2, so that the dense oxide films on the surfaces of the first water and oxygen consuming sublayer 121 and the first water and oxygen consuming sublayer 121 can block the ammonia gas or the derivative of ammonia from diffusing into the first water and oxygen consuming sublayer 121, that is, block the ammonia gas or the derivative of ammonia from diffusing into the thin film encapsulation layer 12, thereby effectively reducing the probability of generating bubbles between the film layers of the thin film encapsulation layer 12, and further effectively improving the problem of encapsulation failure of the OLED display device.
