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 apparent that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments that can be obtained by a person skilled in the art without making any inventive step based on the embodiments in the present application belong to the protection scope of the present application.
As mentioned in the background, the display panel includes sub-pixels of multiple colors, and usually includes sub-pixels of primary colors, that is, includes sub-pixels of red, green and blue, when the display panel emits light, the actual light-emitting area that can be observed is larger than the area of the light-emitting material itself due to the propagation of light in the medium surrounding the sub-pixels, the light emitted by a single sub-pixel of red, green and blue will affect the light emission of other sub-pixels, and will also be affected by the light emitted by the sub-pixels surrounding, and the mixing of different lights will cause color mixing, resulting in color shift of the display panel.
Based on the above, the present application provides a display panel, which includes a substrate, a light-emitting layer, and a color shift adjusting structure disposed on a side of the light-emitting layer away from the substrate; the light emitting layer is divided into a pixel opening area and a pixel defining area surrounding the pixel opening area, the color shift adjusting structure includes a light absorbing portion and a light reflecting portion, the light reflecting portion is disposed around the pixel opening area, and at least a portion of a light reflecting outer circumferential side is provided with the light absorbing portion. By arranging the color shift adjusting structure comprising the light absorbing part and the light reflecting part, light emitted by the single sub-pixel is reflected by the light reflecting part in the transmission process and is not transmitted to the upper parts of other surrounding pixels, so that good reflection of emergent light in all directions can be ensured; meanwhile, a small amount of light which is not intercepted successfully is absorbed by the light absorption part at the periphery of the light reflection part, so that the light mixing among the sub-pixels is avoided, and the color cast condition of the display panel is improved.
Fig. 1 is a schematic top view of a display panel according to an embodiment of the present disclosure; fig. 2 is a schematic top view of a display panel according to yet another embodiment of the present disclosure; FIG. 3 is a cross-sectional view of the display panel of FIG. 1 taken along a section BB; fig. 4 is a schematic cross-sectional structural diagram of a display panel according to another embodiment of the present disclosure. The details of the embodiments of the present application are described below with reference to fig. 1 to 4. Taking the display panel as an OLED display panel as an example, the display panel includes a substrate 100, the substrate 100 includes a substrate and a driving layer, the substrate may be a flexible substrate, such as a polyimide substrate, to meet the flexibility requirement of the display panel, the substrate may also be a rigid substrate, such as a glass substrate, the driving layer may be a thin film transistor driving layer, and the driving light-emitting layer implements a display function. The light emitting layer 200 is divided into a pixel opening area 210 and a pixel defining area 220 surrounding the pixel opening area, a light emitting material layer is disposed in the pixel opening area 210, in order to improve light emitting efficiency, a hole auxiliary layer and an electron auxiliary layer are further disposed on two sides of the light emitting material layer respectively, and specifically, one or more of auxiliary film layers such as a hole injection layer, a hole transport layer, an electron injection layer, and an electron transport layer may be included, of course, the display panel further includes an anode and a cathode, and the pixel defining area 220 is disposed around the pixel opening area 210, so that the display panel forms an independent sub-pixel light emitting area.
The color shift adjusting structure 400 includes a light absorbing portion 420 and a light reflecting portion 410, the light reflecting portion 410 is disposed around the pixel opening area 210, and the light reflecting portion 410 and the pixel opening area 210 are disposed in a one-to-one correspondence manner, so that the light emitting range of a single pixel opening area 210 is limited, and color mixing of adjacent sub-pixels is avoided. At least part of the outer peripheral side of the light reflecting portion 410 is provided with the light absorbing portion 420, that is, the color shift adjusting structure 400 further includes the light absorbing portion 420, and the light absorbing portion 420 is provided at the periphery of the light reflecting portion 410 around the light reflecting portion 410, and it is understood that the light reflecting portion 410 is provided around the pixel opening area 210, and therefore, the light absorbing portion 420 also surrounds the pixel opening area 210. As shown in fig. 1, the light absorbing portions 420 may correspond to the pixel opening areas 210 one by one, or a part of the periphery of the pixel opening area 210 may be surrounded by the light absorbing portion 420, specifically, as shown in fig. 2, the periphery of the pixel opening area 210 adjacent to one pixel opening area 210 is provided with the light absorbing portion 410, even if the pixel opening area 210 is not separately provided with the light absorbing portion 420 at the periphery thereof, the light not reflected by the light reflecting portion 410 can be shielded and absorbed by the light absorbing portion 420 of the adjacent pixel opening area, so as to avoid color mixing between the adjacent pixel opening areas 210. The light absorbing part 420 can absorb the outgoing light of a large angle, and the light emitted from the pixel opening region 210 can be absorbed by the light absorbing part 420 even if not reflected by the light reflecting part 410, thereby further avoiding color mixing and improving the display effect.
The display panel is a top-emission display panel, the substrate 100, the light-emitting layer 200 and the color shift adjusting structure 400 are stacked, and the color shift adjusting structure 400 is arranged above the light-emitting layer 200 and located on one side of the light-emitting layer 200, which is far away from the substrate 100, and is consistent with the light-emitting direction of the display panel, so that the color shift adjusting effect is achieved.
The color shift adjusting structure 400 can be disposed in an existing film layer to prevent the increase of the thickness of the display panel due to the increase of the film layer. The color shift adjusting structure 400 may also be disposed in a newly introduced film layer. The color shift adjusting structure 400 may be disposed in an organic layer, improving the flexibility and stress resistance of the display panel. Since the color shift adjusting structure 400 needs to perform the functions of light reflection and light absorption, the color shift adjusting structure 400 is disposed in a layer as close to the light emitting layer 200 as possible, thereby further reducing color mixing.
The color shift adjusting structure 400 includes a light absorbing portion 420 and a light reflecting portion 410, and the thicknesses of the light absorbing portion 420 and the light reflecting portion 410 may be the same, and the thickness refers to the dimension of the light emitting layer 200 in the direction approaching the substrate 100. It can be understood that the color mixing degree of the display panel is related to the thickness of the light reflecting portion 410, and therefore, the light reflecting portion 410 needs to have a certain thickness, and the large-angle outgoing light that is not reflected by the light reflecting portion 410 can be absorbed by the light absorbing portion 420 surrounding the pixel opening area 210 or absorbed by the light absorbing portion 420 corresponding to the adjacent pixel opening area, and therefore, the color mixing degree of the display panel is also related to the thickness of the light absorbing portion 420, and in addition, setting the thickness of the light absorbing portion 420 to be the same as the thickness of the light reflecting portion 410 facilitates reducing the process difficulty. Of course, in other embodiments, the light-absorbing part 420 and the light-reflecting part 410 may be provided to have different thicknesses according to actual needs.
In one embodiment, the display panel includes an encapsulation layer 300, the encapsulation layer 300 includes a first organic layer 310, and the color shift adjusting structure 400 is disposed in the same layer as the first organic layer 310, that is, the color shift adjusting structure 400 is formed in the encapsulation layer 300, so as to prevent the display panel from increasing in thickness while avoiding color mixing of the display panel.
When the encapsulation layer 300 includes a plurality of organic layers, the color shift adjusting structure 400 is disposed in the organic layer closest to the substrate 100 side, thereby improving the effect of avoiding color mixing.
Further, the thickness of the light reflecting portion 410 and/or the thickness of the light absorbing portion 420 may be the same as the thickness of the film layer on which the light reflecting portion 410 is disposed, such as the thickness of the first organic layer 310 and the light reflecting portion 410 and/or the thickness of the first organic layer 310 and the light absorbing portion 420 are the same when the color shift adjusting structure 400 is disposed on the first organic layer 310. Alternatively, the thickness of the light reflecting portion 410 and/or the thickness of the light absorbing portion 420 are less than the thickness of the first organic layer 310, and the first organic layer 310 covers the end surface of the light reflecting portion 410 and/or the end surface of the light absorbing portion 420, so as to protect the color shift adjusting structure 400 and prevent the color shift adjusting structure 400 from affecting adjacent film layers. If when buckling display panel, display panel takes place the deformation, and first organic layer 310 may have certain deformation, if buckle, compress, set up colour cast adjustment structure 400 into the thickness that thickness is less than first organic layer 310, even display panel takes place the deformation, colour cast adjustment structure 400 also can not take place to contradict with the adjacent rete of first inorganic layer 320 to avoid exerting an influence to display panel encapsulation effect, further improve display panel's stability.
In an embodiment, when the color shift adjusting structure 400 is located in the first organic layer 310, a distance between the upper surface of the color shift adjusting structure 400 and the upper surface of the first organic layer 310 is greater than a distance between the lower surface of the color shift adjusting structure 400 and the lower surface of the first organic layer 310, so that the color mixing prevention effect can be improved on the premise of improving the bending resistance. More specifically, the light reflecting part 410 and the light absorbing part 420 are located within the first organic layer 310, a distance between an upper surface of the light reflecting part 410 and an upper surface of the first organic layer 310 is greater than a distance between a lower surface of the light reflecting part 410 and a lower surface of the first organic layer 310, and a distance between an upper surface of the light absorbing part 420 and an upper surface of the first organic layer 310 is greater than a distance between a lower surface of the light absorbing part 420 and a lower surface of the first organic layer 310.
Further, the color shift adjusting structure 400 is located in the first organic layer 310, and a distance between a surface of the color shift adjusting structure 400 and a corresponding surface of the first organic layer 310 is less than 10% of a thickness of the color shift adjusting structure 400.
With reference to fig. 3 and 4, in this embodiment, the encapsulation layer 300 includes a first inorganic layer 320, a first organic layer 310, and a second inorganic layer 330, which are sequentially stacked, and the second inorganic layer 330 is located on a side of the first organic layer 310 facing away from the substrate 100. The inorganic layer has a higher water vapor blocking function compared with the organic layer, and in the structure of the packaging layer 300, the thickness of the organic layer is far larger than that of the inorganic layer, so that the requirement of the thickness of the color cast adjusting structure 400 can be met, and the color cast adjusting structure 400 is arranged in the organic layer to ensure the flexible requirement of the display panel.
Further, when the light absorbing part 420 is provided on the outer peripheral side of the light reflecting part 410, as shown in fig. 4, the outer peripheral surface of the light reflecting part 410 and the inner peripheral surface of the light absorbing part 420 may be disposed in contact, and as shown in fig. 1 and 3 in combination, a gap C may be provided between the light reflecting part 410 and the light absorbing part 420. When there is a gap between the light reflecting part 410 and the light absorbing part 420, the light can be reflected and absorbed for many times between the light reflecting part 410 and the light absorbing part 420, the light absorbing effect is improved, and the micro reflection and the light absorption can be realized between the light absorbing part 420 and the light absorbing part 420, so that the color purity of the display panel is improved.
When the encapsulation layer 300 includes the first inorganic layer 320, the first organic layer 310 and the second inorganic layer 330, and the color shift adjusting structure 400 is disposed in the first organic layer 310, the following method may be specifically adopted to prepare the encapsulation layer 300 structure: first, forming a first inorganic layer 320, specifically depositing the first inorganic layer by using a chemical vapor deposition method; then preparing the first organic layer 310 by adopting a chemical vapor deposition method, and reserving spaces of the light absorbing part 420 and the light reflecting part 410 by using a mask plate when preparing the first organic layer 310; then, a light absorption part 420 is obtained through deposition, in the process, the position of the light absorption part 420 is limited by using a mask plate, and a space for preparing the light reflection part 410 is reserved, wherein the specific deposition mode can be physical vapor deposition, and the material of the light absorption part 420 can be black shading metal; then depositing to obtain a light reflecting part 410, specifically adopting physical vapor deposition, wherein the material of the light reflecting part 410 can be light reflecting metal; and finally, depositing a second inorganic layer by adopting a chemical vapor deposition method.
In order not to affect the normal display of the display panel, the color shift adjusting structure 400 is disposed around the pixel opening area 210, and thus the color shift adjusting structure 400 is a hollow structure, or the light reflecting portion 410 and the light absorbing portion 420 are hollow structures, so as to surround the pixel opening area 210.
In an embodiment, the light reflecting portion 410 is a hollow cylinder, such as a hollow cylinder, a hollow elliptic cylinder, a hollow prism, etc., it can be understood that the cylinder structure has a smooth circumferential surface, and the light reflecting portion 410 has a smooth inner circumferential surface, which can improve the light reflecting ability of the light reflecting portion 410 and improve the light emitting efficiency of the display panel.
Preferably, the projection profile of the light reflecting portion 410 on the substrate 100 is circular or elliptical, that is, the light reflecting portion 410 is a hollow cylinder or a hollow elliptic cylinder, and at this time, the inner peripheral surface of the light reflecting portion 410 is a smooth surface, and there is no uneven structure such as a prism-like corner, and the light reflecting ability of the light reflecting portion 410 to light can be improved.
In one embodiment, the shape and size of the inner contour of any cross section of the light reflecting portion 410 are the same along the axial direction of the light reflecting portion 410, that is, the shape and size of the inner circumference of the light reflecting portion 410 are the same in any thickness, so that the actual light emitting area of the pixel opening region 210 is the same as the size of the inner circumference contour defined by the light reflecting portion 410.
More specifically, the inner contour of the projection of the light reflecting portion 410 on the light emitting layer 200 is the same as the pixel opening area 210, thereby avoiding enlarging the actual light emitting area. When the pixel opening area 210 has a polygonal shape, the inner contour of the projection of the light reflecting portion 410 on the light emitting layer 200 overlaps with the circumcircle of the pixel opening area 210, so that the light reflecting portion 410 has a smooth surface, the light reflecting performance of the light reflecting portion 410 is improved, and the actual light emitting area of each sub-pixel is prevented from being enlarged. Under the condition that the length and width ratio of the pixel opening area is large, a light reflecting part with an elliptical ring-shaped cross section can be adopted, and the distance from the edge of the pixel opening area to the inner contour of the light reflecting part in the long side direction of the pixel opening is not more than the length of the shortest side of the pixel opening, so that the expansion of the light emitting area of the pixel is avoided, and the color mixing is avoided.
In one embodiment, the light transmittance of the light absorbing part 420 is not greater than 10%, so as to ensure the light absorbing effect, and the specific material of the light absorbing part 420 may be industrial pure iron containing more than 90% of iron, cast iron containing 2% to 4% of carbon, iron alloy such as carbon steel containing less than 2% of carbon, and any one of chromium, manganese and their alloys. The reflection rate of the reflection part is not less than 80 percent, thereby ensuring the reflection effect. Specifically, the light reflecting portion 410 is a light reflecting metal, and the specific material is any one of Al, Ag, Au, and Cu.
The application also provides a display device, which comprises the display panel, and the display panel comprises the light reflecting part 410 and the light absorbing part 420, so that light emitted by a single pixel is reflected by the light reflecting part 410 in the transmission process and is not transmitted to the upper parts of other surrounding pixels, and good reflection of emergent light rays in all directions can be ensured; meanwhile, a small amount of light which is not successfully intercepted is absorbed by the light absorption part 420 at the periphery of the light reflection part 410, so that the light among pixels is prevented from being mixed, and the color cast condition of the display panel is improved. The display device including the display panel also has the same advantageous effects as the display panel.
Although the embodiments of the present application have been described in connection with the accompanying drawings, the embodiments may be arbitrarily combined, and those skilled in the art may make various modifications and variations without departing from the spirit and scope of the application, such modifications and variations falling within the scope defined by the appended claims.
