The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the present invention.
Referring to fig. 1, an embodiment of the invention provides a display panel, which includes an array substrate 10, a light emitting layer 20, and an encapsulation layer 30, wherein the light emitting layer 20 is disposed between the array substrate 10 and the encapsulation layer 30; a surface of the encapsulation layer 30 facing the light emitting layer 20 and/or a surface of the encapsulation layer 30 facing away from the light emitting layer 20 is provided with a first frosted structure 303.
Taking the orientation shown in fig. 1 as an example, in the present embodiment, the light emitting layer 20 disposed between the array substrate 10 and the encapsulation layer 30 includes: the light emitting device includes a pixel defining layer 201 and a light emitting unit 202, the light emitting unit 202 is plural, the light emitting units 202 are arranged at intervals, the pixel defining layer 201 is used for separating the light emitting units 202, and specifically, the light emitting unit 202 may be an organic light emitting unit. The array substrate 10 is disposed at the lower part of the pixel defining layer 201, and a plurality of thin film transistors are disposed in the array substrate 10, each thin film transistor corresponding to one light emitting unit 202; when the display panel is in operation, the tft controls the corresponding light emitting unit 202 to emit light.
Preferably, in this embodiment, when the light emitting unit 202 is an organic light emitting unit, the display panel may be a flexible display panel, that is, the display panel may be bent to adapt to different application environments, so as to improve user experience.
In this embodiment, the first frosted structure 303 may be only disposed on the surface of the encapsulation layer 30 facing the light-emitting layer 20, or the first frosted structure 303 may be only disposed on the surface of the encapsulation layer 30 facing away from the light-emitting layer 20, or the first frosted structure 303 may be disposed on both the surface of the encapsulation layer 30 facing the light-emitting layer 20 and the surface facing away from the light-emitting layer 20.
In this embodiment, the first frosted structure 303 is not limited, as long as it is ensured that after external light is incident into the display panel, reflected light is formed on the metal layer of the display panel, and when the reflected light is emitted to the encapsulation layer 30, the reflected light is diffusely reflected on the first frosted structure 303; compared with the case where the first frosted structure 303 is not provided, light passing through the encapsulation layer 30 can be reduced, so as to reduce reflected light emitted by the display panel, and improve the resolution of the display panel.
For example: the first frosted structure 303 may include protrusions disposed on a surface of the encapsulation layer 30 facing the light emitting layer 20 and/or a surface of the encapsulation layer 30 facing away from the light emitting layer 20; the protrusions may have a regular shape such as a cylindrical shape or a prismatic shape, but may have other irregular shapes. With continued reference to fig. 1, in a preferred implementation, the first frosted structure 303 includes a first raised portion and a second raised portion alternately arranged, and in a cross section perpendicular to the display panel, the cross section of the first raised portion is a regular trapezoid, and the cross section of the second raised portion is an inverted trapezoid.
In this embodiment, an electrode layer electrically connected to the thin film transistor is disposed between the array substrate 10 and the light emitting layer 20, the electrode layer corresponds to the light emitting unit 202, and the metal layer of the display panel may be a metal layer or an electrode layer in the array substrate 10; when the external light entering the display panel is emitted to the metal layer, a reflected light is formed on the metal layer.
In this embodiment, the encapsulation layer 30 may be composed of the inorganic layer 302, and in this case, the encapsulation layer 30 may be disposed on a surface of the inorganic layer 302 facing the light-emitting layer 20 and/or the encapsulation layer 30 is disposed on a surface of the inorganic layer 302 facing away from the light-emitting layer 20.
Preferably, the encapsulation layer 30 includes an organic layer 301 and an inorganic layer 302 stacked together, and the first frosted structure 303 is disposed on the organic layer 301. The encapsulating layer 30 including the organic layer 301 and the inorganic layer 302 can improve the barrier property against moisture and oxygen and further improve the sealing property, as compared with the encapsulating layer 30 including only the inorganic layer 302. In particular, the first frosted structure 303 may be disposed on a surface of the organic layer 301 facing the light-emitting layer 20 and/or the first frosted structure 303 may be disposed on a surface of the organic layer 301 facing away from the light-emitting layer 20.
Further, a plurality of organic layers 301 and inorganic layers 302 are provided, the organic layers 301 and the inorganic layers 302 are alternately disposed, and the first frosted structure 303 is disposed on at least one of the organic layers 301. The organic layer 301 and the inorganic layer 302 alternately disposed may further improve the sealability of the encapsulation layer 30.
Specifically, the first frosted structure 303 may be disposed on one organic layer 301 or several organic layers 301 of the encapsulation layer 30, and of course, the first frosted structure 303 may be disposed on all the organic layers 301 on the encapsulation layer 30; with the increase of the number of the organic layers 301 provided with the first frosted structure 303, the amount of light scattered when the reflected light passes through the encapsulation layer 30 is gradually increased, the amount of the corresponding reflected light capable of passing through the encapsulation layer 30 is correspondingly decreased, and the resolution of the display panel is gradually increased.
In one implementation, the bumps may be fabricated separately from the encapsulation layer 30. Specifically, after the encapsulation layer 30 is formed, a pre-fabricated bump is provided on the encapsulation layer 30.
In other implementations, the first frosted structure 303 includes a plurality of raised portions spaced apart and integrally formed with the organic layer 301. The first protruding portion is integrally formed with the organic layer 301 in the encapsulation layer 30, so that the manufacturing difficulty of the display panel can be further simplified.
Taking the first frosted structure 303 as an example, the first frosted structure 303 is disposed on the surface of the encapsulation layer 30 away from the light-emitting layer 20, the encapsulation layer 30 may be manufactured first, then the mask with a plurality of shielding portions is covered on the encapsulation layer 30, then the mask is exposed, so that the encapsulation layer 30 outside the shielding portions is exposed, then the exposed encapsulation layer 30 is removed, that is, the protruding portions are formed on the surface of the encapsulation layer 30 away from the light-emitting layer 20, and the plurality of protruding portions form the first frosted structure 303. It should be noted that the exposure depth needs to be controlled so that the exposure depth is smaller than the thickness of the encapsulation layer 30, so as to avoid the encapsulation failure caused by removing all the encapsulation layer 30 except the shielding portion.
When the first frosted structure 303 is disposed on the surface of the encapsulation layer 30 facing the light emitting layer 20, a plurality of recesses may be disposed on the film layer below the encapsulation layer 30, and then the encapsulation layer 30 is formed through a deposition process; when the encapsulation layer 30 is formed, a part of the material is filled in the recess to form the first frosted structure 303. When the first frosted structure 303 is disposed on both the surface of the encapsulation layer 30 facing the light-emitting layer 20 and the surface of the encapsulation layer 30 facing away from the light-emitting layer 20, it is required to ensure that the exposure depth when the upper surface of the encapsulation layer 30 is exposed is less than the thickness of the encapsulation layer 30, so as to prevent the encapsulation failure.
In other embodiments, the protrusion may be formed separately, that is, the protrusion is made of a transparent material different from that of the organic layer 301, and after the organic layer 301 is formed, the protrusion is disposed on the organic layer 301.
The working process of the display panel provided by the embodiment is as follows: the external light irradiates the display panel from one side of the packaging layer 30 departing from the light-emitting layer 20, and the light passes through the packaging layer 30 and the light-emitting layer 20 to enter the display panel and then is reflected on the metal layer on the display panel to form reflected light; the reflected light is emitted to the encapsulation layer 30, and when the reflected light passes through the encapsulation layer 30, the reflected light is diffusely reflected at the first frosted structure 303 on the encapsulation layer 30 to scatter a part of the reflected light, and the rest of the reflected light is emitted from the display panel.
In the display panel provided by the embodiment, the light emitting layer 20 is located between the array substrate 10 and the encapsulation layer 30, and a first frosted structure 303 is arranged on a surface of the encapsulation layer 30 facing the light emitting layer 20 and/or a surface of the encapsulation layer 30 facing away from the light emitting layer 20; after the external light enters the display panel, reflected light is formed on the metal layer in the display panel, and when the reflected light passes through the packaging layer 30, the reflected light is subjected to diffuse reflection at the first frosted structure 303, so that part of the reflected light is scattered; compared with the case where the first frosted structure 303 is not provided, the amount of reflected light passing through the encapsulation layer 30 is reduced, and thus the amount of reflected light emitted from the display panel is reduced, and the resolution of the display panel is improved.
In this embodiment, the display panel further includes a filter layer 40 located on a side of the encapsulation layer 30 away from the light emitting layer 20; the light emitting layer 20 includes a pixel defining layer 201 and a light emitting unit 202, the pixel defining layer 201 is provided with a pixel opening, and the light emitting unit 202 is disposed in the pixel opening; the filter layer 40 includes an optical filter 402 and a light-shielding layer 401 stacked with the pixel defining layer 201, the light-shielding layer 401 is provided with an optical filter opening facing the pixel opening, and the optical filter 402 is disposed in the optical filter opening; a surface of the filter 402 facing the light-emitting layer 20 and/or a surface of the filter 402 facing away from the light-emitting layer 20 are provided with second frosted structures 4021. When the reflected light passes through the second frosted structure 4021 on the surface of the filter 402 facing the light-emitting layer 20, diffuse reflection occurs to reduce the reflected light passing through the filter 402, so as to further reduce the reflected light provided by the display panel. When the reflected light passes through the second frosted structure 4021 on the surface of the filter 402 facing away from the light-emitting layer 20, scattering occurs at the second frosted structure 4021 to scatter the reflected light, and because the position of the user is fixed, compared with the case where the second frosted structure 4021 is not provided, the reflected light received by the user can be reduced.
The light-shielding layer 401 is made of an opaque material, so that the light-shielding layer 401 can block the reflected light from being emitted, and therefore the reflected light can only be emitted through the optical filter 402 in the optical filter; the reflected light emitted from the display panel can be further reduced as compared with when the filter layer 40 is not provided. In addition, the filter 402 only allows a certain color light to exit, and the reflected light passing through the filter 402 can be filtered to reduce the reflected light emitted from the display panel again; for example, the light emitting unit 202 opposite to the filter 402 only emits red light, the filter 402 allows red light to pass through, and when the reflected light passes through the filter 402, only the red light in the reflected light can pass through the filter 402.
Further, in order to make all the light emitted from the light emitting unit 202 exit through the filter opening, the shape of the filter opening may be the same as the pixel opening, and the area of the filter opening may be the same as the area of the pixel opening.
In this embodiment, the structure of the second sanding structure 4021 is substantially similar to that of the first sanding structure 303, and reference is made to the description of the first sanding structure 303, which is not repeated herein.
The second frosted structure 4021 and the optical filter 402 in this embodiment may be manufactured separately, and accordingly, taking the structure in which the second frosted structure 4021 is disposed on the surface of the optical filter 402 away from the light-emitting layer 20 as an example, after the optical filter 402 is manufactured, the second frosted structure 4021 manufactured in advance is mounted on the surface of the optical filter 402 away from the light-emitting layer 20, so as to achieve connection between the second frosted structure and the optical filter 402.
In this embodiment, preferably, the second frosted structure 4021 is integrally formed with the optical filter 402, at this time, the optical filter 402 may be formed first, a mask plate with a plurality of shielding portions is covered on the optical filter 402 after the optical filter 402 is cut, then the mask plate is exposed, so that the optical filter 402 except the shielding portions is exposed, and then the exposed optical filter 402 is removed, that is, the second frosted structure 4021 may be formed on the surface of the optical filter 402 away from the light-emitting layer 20.
In this embodiment, a third frosted structure 4011 is disposed on a surface of the light-shielding layer 401 away from the light-emitting layer 20. When light shines on filter layer 40, there will be some light to take place the reflection on light shield layer 401, and third dull polish structure 4011 can make light give play to diffuse reflection on light shield layer 401 deviates from the surface of luminescent layer 20, because the user position of the display panel outside is fixed, compare with not setting up third dull polish structure 4011, because the light that reflects on light shield layer 401 deviates from the surface of luminescent layer 20 is scattered for the reflection light that the user received reduces.
In this embodiment, the third frosted structure 4011 and the first frosted structure 303 have substantially the same structure, and are not further described herein.
Specifically, the third frosted structure 4011 on the surface of the light-shielding layer 401 away from the light-emitting layer 20 can be formed simultaneously with the second frosted structure 4021 on the surface of the optical filter 402 away from the light-emitting layer 20, so as to further simplify the processing difficulty of the display panel; for example, the third frosted structure 4011 on the surface of the light-shielding layer 401 away from the light-emitting layer 20 and the second frosted structure 4021 on the surface of the optical filter 402 away from the light-emitting layer 20 may be formed simultaneously by the same mask. For convenience of processing, the third frosted structure 4011 may be formed on the surface of the light-shielding layer 401 facing the light-emitting layer 20, at the same time as the second frosted structure 4021 on the surface of the filter 402 facing the light-emitting layer 20 is formed.
In this embodiment, the surface of the array substrate 10 facing the light emitting layer 20 is provided with an electrode layer 50, and a side of the electrode layer 50 facing the light emitting layer 20 is provided with a fourth frosted structure 601.
The fourth frosted structure 601 may be disposed on a surface of the electrode layer 50 facing the light-emitting layer 20, where the electrode layer 50 is generally mainly made of metal, and external light incident on the display panel forms reflected light on the surface of the electrode layer 50 facing the light-emitting layer 20; with this arrangement, external light can be diffusely reflected on the fourth frosted structure 601 to scatter the reflected light formed on the electrode layer 50; due to the fact that the position of the user is fixed, the fourth frosted structure 601 is not arranged, and reflected light received by the user is reduced. The electrode layer 50 may be an anode or a cathode.
Further, when the display panel includes the filter layer 40 located on the side of the encapsulation layer 30 away from the light-emitting layer 20, since the external light is diffusely reflected on the electrode layer 50, the reflected light is scattered, most of the reflected light is absorbed by the light-shielding layer 401, and only part of the reflected light is emitted through the filter 402; compared with the case where the fourth frosted structure 601 is not provided, the amount of reflected light provided by the display panel can be reduced, and the resolution of the display panel can be improved.
In this embodiment, the fourth sanding structure 601 is substantially similar to the first sanding structure 303, and is not described herein with reference to the description of the first sanding structure 303.
In this embodiment, the conductive film 60 is disposed on the surface of the electrode layer 50 facing the light-emitting layer 20, and the fourth frosted structure 601 is disposed on the surface of the conductive film 60 facing the light-emitting layer 20. The thickness of the electrode layer 50 is small, and it is difficult to form the fourth frosted structure 601 on the electrode layer 50; the fourth frosted structure 601 is disposed on the conductive film 60, and compared with the case where the fourth frosted structure 601 is disposed on the electrode layer 50, the manufacturing difficulty of displaying the fourth frosted structure 601 is simplified.
In this embodiment, the material of the conductive film 60 is not limited as long as the conductive film 60 has good conductivity, for example: the conductive film 60 may be an indium tin oxide film, a metal film, or the like. Preferably, the conductive film 60 is a graphene film or a polyelectrolyte conductive film; the flexibility of the graphene and the polyelectrolyte is good, and the display panel can be prevented from being broken when being bent.
When the conductive film 60 is mainly made of a transparent material such as a graphene film, the fourth frosted structure 601 may be further disposed on a surface of the conductive film 60 away from the light-emitting layer 20.
With continued reference to fig. 1, there is also provided in other embodiments a display device comprising: the housing is the display panel as described above, and the display panel is provided in the housing.
The display device can be a product or a component with a display function, such as a mobile phone, a tablet personal computer, a television, a display, an electronic book, electronic paper, an intelligent watch, a notebook computer, a digital photo frame or a navigator.
Preferably, the display device is a flexible display device, the corresponding display panel is a flexible display panel, and the flexible display panel is bent to adapt to different application environments and improve user experience.
In the display device provided by the embodiment, the light-emitting layer 20 is located between the array substrate 10 and the encapsulation layer 30, and the surface of the encapsulation layer 30 facing the light-emitting layer 20 and/or the surface of the encapsulation layer 30 facing away from the light-emitting layer 20 are provided with the first frosted structure 303; after the external light enters the display panel, reflected light is formed on the metal layer in the display panel, and when the reflected light passes through the packaging layer 30, the reflected light is subjected to diffuse reflection at the first frosted structure 303, so that part of the reflected light is scattered; compared with the case where the first frosted structure 303 is not provided, the amount of reflected light passing through the encapsulation layer 30 is reduced, and thus the amount of reflected light emitted from the display panel is reduced, and the resolution of the display panel is improved.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
