Referring to fig. 1-2, an embodiment of the present application provides a display panel 10. The display panel 10 includes a substrate 100, an organic light emitting layer 200, a protective layer 300, and an encapsulation layer 20. The substrate 100 includes a display area 110 and a non-display area 120. The non-display area 120 is disposed around the display area 110. The organic light emitting layer 200 is disposed in the display region 110. The encapsulation layer 20 includes a first water absorbent layer 400 disposed in the display region 110 and a second water absorbent layer 500 disposed in the non-display region 120 and contacting the first water absorbent layer 400. The water absorption capacity of the second water absorption layer 500 is greater than that of the first water absorption layer 400.
In this embodiment, the substrate 100 may be a flexible material or a rigid material. A driving circuit layer 800 may be formed on a surface of the substrate 100, and the organic light emitting layer 200 may be formed on a surface of the driving circuit layer 800. In one embodiment, the material of the substrate 100 may be polyetherimide, polyethylene terephthalate, or polyimide. The display area 110 may be used to display a pattern animation. The non-display area 120 may serve as a bezel of the display panel 10. The organic light emitting layer 200 may include a plurality of light emitting material regions arranged in an array. The encapsulation layer 20 may prevent water and oxygen from intruding into the organic light emitting layer 200. The encapsulation layer 20 includes a hierarchical structure formed by stacking organic materials and inorganic materials.
The first water absorbent layer 400 and the second water absorbent layer 500 may be used to guide out water and oxygen that have intruded into the organic light emitting layer 200. When water and oxygen intrude into the organic light emitting layer 200, the first water absorption layer 400 may absorb water and oxygen first, and since the second water absorption layer 500 is in contact with the first water absorption layer 400 and the water absorption capacity of the second water absorption layer 500 is greater than that of the first water absorption layer 400, the water and oxygen concentration of the second water absorption layer 500 is less than that of the first water absorption layer 400. At this time, the water and oxygen in the first water absorption layer 400 will diffuse to the non-display area 120 along the path of the second water absorption layer 500, so that the water and oxygen in the organic light emitting layer 200 can be guided out to protect the organic light emitting layer 200 from being damaged.
In one embodiment, the second water absorbent layer 500 may have a stripe diffusion structure, so that water and oxygen absorbed by the first water absorbent layer 400 may be guided to the periphery of the display panel 10. The water and oxygen may be discharged from the display panel 10 through the second water absorbent layer 500.
In one embodiment, the material may be a super absorbent resin material having different water absorption rates. In one embodiment, the material of the first water absorbent layer 400 and the second water absorbent layer 500 may be polyacrylate, polyvinyl alcohol, or hydroxymethylated cellulose. It is understood that the first water-absorbent layer 400 and the second water-absorbent layer 500 may be made of the same material as long as the water-absorbent capacity of the second water-absorbent layer 500 is greater than that of the first water-absorbent layer 400.
In one embodiment, when the materials of the first water-absorbing layer 400 and the second water-absorbing layer 500 are the same, different water-absorbing capacities can be achieved by changing the manufacturing process of the first water-absorbing layer 400 and the second water-absorbing layer 500. In one embodiment, the first absorbent layer 400 and the second absorbent layer 500 are super absorbent resins. The super absorbent resin may be prepared by acrylic acid, distilled water, sodium bicarbonate, acrylamide, methylenebisacrylamide, potassium persulfate. By adding the acrylic acid, the water absorption capacity of the super absorbent resin can be gradually increased. This is because the water absorption property of the carboxyl group is higher than that of the amide group, and the water absorption property of the super absorbent resin increases with the increase of the carboxyl group.
In one embodiment, the first water-absorbing layer 400 and the second water-absorbing layer 500 may be manufactured by the following processes: coating and curing the first water absorbent layer 400 on the surface of the substrate 100, and patterning the first water absorbent layer 400, wherein the patterning process may include exposure, development, and peeling processes. Then the second water-absorbing layer 500 is coated and cured, the second water-absorbing layer 500 is patterned, and finally, packaging is performed. Or the first water absorption layer 400 is attached to the surface of the substrate 100 by controlling the aperture and the attachment precision of the first water absorption layer 400, the second water absorption layer 500 is attached to the surface of the substrate 100 by controlling the attachment precision of the second water absorption layer 500, and finally, packaging is performed.
In the display panel 10 provided in the embodiment of the present application, the first water absorption layer 400 is located in the display area 110. The second water absorbent layer 500 is positioned in the non-display region 120 and contacts the first water absorbent layer 400. Since the water absorption capacity of the second water absorption layer 500 is greater than that of the first water absorption layer 400, water and oxygen in the organic light emitting layer 200 can be absorbed by the first water absorption layer 400. The water and oxygen of the first water absorption layer 400 can be merged to the non-display region 120 through the second water absorption layer 500, and thus the organic light emitting layer 200 can be effectively protected from being damaged. In the case where external water oxygen has invaded the display region 110, the first water absorption layer 400 and the second water absorption layer 500 can absorb water oxygen in time, so that the degree of the water oxygen affecting the organic light emitting layer is reduced, and the accumulation of water oxygen in the organic light emitting layer 200 is prevented.
In one embodiment, the encapsulation layer 20 includes a protective layer 300. The first water absorbent layer 400 is disposed on a side of the protection layer 300 away from the organic light emitting layer 200 and is in direct contact with the protection layer 300. The first water absorbing layer 400 may be a thin film material, and thus may avoid affecting the light emitting effect of the organic light emitting layer 200. In one embodiment, the first absorbent layer 400 may be a continuous, full-face film material. The continuous entire surface of the thin film material may cover a side of the protection layer 300 away from the organic light emitting layer 200. In one embodiment, the first absorbent layer 400 may also be a hollow mesh structure. The net-shaped structure can be integrally formed or can be formed by weaving. The first water absorption layer 400 may be formed on the surface of the protective layer 300. Due to the protection of the protective layer 300, the organic light emitting layer 200 is not damaged during the process of manufacturing the first water absorption layer 400. It is understood that the protective layer 300 may include a stacked structure of an organic layer and an inorganic layer. The protective layer 300 may encapsulate the organic light emitting layer 200 on the surface of the substrate 100.
In one embodiment, the projection of the first water absorption layer 400 on the substrate 100 does not exceed the projection range of the protection layer 300 on the substrate 100. The protective layer 300 may completely cover the organic light emitting layer 200. The area surrounded by the outer edges of the first water absorption layer 400 is smaller than the area of the protection layer 300, and thus the first water absorption layer 400 cannot contact the organic light emitting layer 200. The organic luminescent layer 200 may be protected from being damaged by the first water absorbent layer 400 by the protective layer 300.
In one embodiment, the organic light emitting layer 200 includes a plurality of pixel units 230 arranged in an array. The first water absorption layer 400 includes a plurality of water absorption bands 440 disposed between the pixel units 230. The absorbent belt 440 gathers in the second absorbent layer 500.
In one embodiment, when the first water absorption layer 400 is located on a side of the protection layer 300 away from the substrate 100, a plurality of the water absorption bands 440 may be arranged at intervals, and a plurality of the pixel units 230 may be disposed between two adjacent water absorption bands 440. That is, the water absorption band 440 may pass between the adjacent pixel units 230. Therefore, the water absorption band 440 can avoid the light emitting surface of the pixel unit 230, and further can avoid affecting the light emitting effect of the pixel unit 230. The water in the water-absorbing belt 440 can be collected to the second water-absorbing layer 500 and can be guided to the outside through the second water-absorbing layer 500.
Referring to fig. 3, in an embodiment, when the first water absorption layer 400 and the organic light emitting layer 200 are disposed at the same layer, several water absorption bands 440 may pass between adjacent pixel units 230. And the water absorption band 440 has a safety distance from the pixel unit 230. The water absorption band 440 can be prevented from affecting the pixel unit 230.
In one embodiment, the distance between any one side of the water absorption strip 440 and the pixel unit 230 is not less than 5 μm in a direction parallel to the plane of the substrate 100. At this distance, the water absorbing band 440 does not affect the operation of the pixel unit 230.
In one embodiment, several of the pixel units 230 may be arranged in a rectangular matrix. The rectangular matrix may have rows and columns of pixel cells. The water absorption band 440 may be disposed between each of the adjacent pixel cell rows and the adjacent pixel cell columns. Therefore, a plurality of the water-absorbing belts 440 can be vertically arranged in the transverse direction to form a net structure. It is understood that several of the pixel units 230 may be arranged in a diamond array or other array structure. The absorbent belts 440 may be arranged in an array configuration with corresponding crossovers. Therefore, the area of the organic light emitting layer 200 can be covered as much as possible while avoiding the influence on the pixel unit 200, and the effect of water and oxygen absorption can be improved.
In one embodiment, the first water absorbent layer 400 includes a water absorbent manifold 430 for collecting the water absorbent belts 440. The second water absorbent layer 500 includes a plurality of water-absorbent flow-guide strips 510. One end of the water absorption flow guide belt 510 is in contact with the water absorption confluence belt 430. The other end of the water absorbing guide strip 510 extends toward the edge of the substrate 100. It is understood that the edges of the network of water-absorbing strips 440 may all be in contact with the water-absorbing bus strips 430. In this case, the water absorbing bus bar 430 may have a ring structure. The ring-like structure may surround the mesh structure. The water-absorbing confluence belt 430 is used for collecting water and oxygen in each water-absorbing belt 440. In one embodiment, the water absorbing bus bar 430 may be disposed adjacent to the non-display region 120. The water intake manifold 430 may serve as a collection outlet to collect and transport water and oxygen drawn by the water intake manifold 440 out of the display area 110. The water and oxygen absorbed by the water absorption belt 440 can be carried to one direction through the water absorption confluence belt 430, so that the water and oxygen can be cleaned conveniently. In one embodiment, the water absorbing capacity of the water absorbing manifold 430 may be greater than the water absorbing capacity of the water absorbing belt 400 or may be equal to the water absorbing capacity of the water absorbing belt 400.
The water absorbing capacity of the water absorbing flow guiding belt 510 is larger than that of the water absorbing confluence belt 430. The water absorbing flow guiding strips 510 may be used to guide water and oxygen merged at the water absorbing flow merging strips 430 to the edges of the substrate 100. The water absorbing guide belt 510 may have a strip structure. The water and oxygen can be prevented from being randomly diffused in the non-display area 120 by the water absorption and flow guide belt 510, and other devices in the non-display area 120 can be prevented from being influenced. In one embodiment, the water absorbing guide strips 510 may partially cover the surface of the water absorbing confluence strips 430, so as to increase the water absorbing area of the water absorbing guide strips 510 and improve the water absorbing efficiency.
Referring to fig. 4, in an embodiment, the display panel 10 further includes an external drying block 600. The external drying block 600 contacts with one end of the water absorption guide belt 510 extending to the edge of the substrate. The water absorbing capacity of the external drying block 600 is greater than that of the water absorbing guide belt 510. The external drying block 600 may be a sphere, cube, or ellipsoid structure. The external drying block 600 may be used to store the water and oxygen collected by the water absorption diversion belt 510. The external drying block 600 can be replaced after saturation. In one embodiment, the external dry block 600 may be disposed at an edge of the display panel 10.
In one embodiment, the end of the water absorption flow guide strip 510 extending to the non-display area 120 is provided with a plug 520. The external drying block 600 is provided with a receiving groove 610. The plug 520 is inserted into the receiving groove 610 to connect the water absorption flow guide strip 510 with the water absorption opening. The plug 520 and the receiving groove 610 are adapted in shape. The plug 520 may have flexibility. The receiving groove 610 may have a snap-fit structure. The plug 520 may be inserted into the receiving groove 610 by stress compression, and the plug 520 may be snapped into the receiving groove 610. When the external drying block 600 needs to be replaced, the plug 520 can be separated from the accommodating groove 610 by overcoming the resistance of the clamping structure with a little force, and the replacement is simple. In one embodiment, the plug 520 may be a ball-shaped structure. The receiving groove 610 may have a corresponding spherical structure. The spherical balls have a large surface area, so that the diffusion rate of water and oxygen in the water absorption flow guide strip 510 to the accommodating groove 610 can be increased.
In one embodiment, the end of the water absorbing and guiding strip 510 extending to the non-display area 120 is provided with the receiving groove 610. The external drying block 600 may be provided with the plug 520.
In one embodiment, the material of the external drying block 600 includes calcium chloride, alumina, silica gel, magnesium sulfate.
In one embodiment, a color changing layer 620 is attached to the surface of the external drying block 600 to indicate the moisture content of the external drying block 600. The color-changing layer 620 may be made of a material that changes color when it encounters water. In one embodiment, the material of the color-changing layer 620 may be anhydrous copper sulfate, anhydrous cobalt chloride, sodium peroxide. When moisture in the external drying block 600 tends to be saturated, the moisture of the external drying block 600 can be gradually diffused to the surface, and the color changing layer 620 changes color when encountering water, so that the external drying block 600 can be replaced at the moment.
In one embodiment, the display panel 10 further includes an outer encapsulation layer 700. The outer packaging layer 700 covers the surface of the first water absorption layer 400. The outer encapsulation layer 700 may be an inorganic material. The outer packaging layer 700 may be silicon oxide, nitrogen oxide, or the like. The external encapsulation layer 700 may further prevent the intrusion of water and oxygen into the display region 110, and may protect the first water absorption layer 400.
In one embodiment, the organic light emitting layer 200 includes a plurality of pixel units 230 arranged in an array. The first water absorption layer 400 is formed as an integrally formed net structure 450. The mesh holes 452 of the mesh structure 450 are disposed corresponding to the pixel units 230, and the area of the mesh holes 452 is larger than that of the pixel units 230.
