In order to better understand the present application, a display panel and a display device according to embodiments of the present application are described in detail below with reference to fig. 1 to 11.

Referring to fig. 1 and 2, an embodiment of the present application provides a display panel 10, which includes an array substrate 1, an isolation structure 3, a light emitting layer 4 and a filter layer 5.

The filter layer 5 is formed on a side of the light emitting layer 4 facing away from the array substrate 1, and includes a filter function portion 51, where the filter function portion 51 extends to a side of the isolation structure 31 facing away from the substrate.

In particular, the front projection of the isolation structure 3 on the substrate may be grid-like.

The display panel 10 provided by the application comprises an array substrate 1, an isolation structure 3, a light-emitting layer 4 and a light-filtering layer 5. The filter layer 5 is formed on one side of the light emitting layer 4 away from the array substrate 1, and comprises a filter function portion 51, wherein the filter function portion 51 can filter light incident into the display panel 10 from the outside, so that the incident quantity of the light is reduced, the reflection quantity of the light incident into the display panel 10 from the internal structure of the display panel 10 is reduced, the outwards divergent light quantity of the light reflected from the internal structure of the display panel 10 can be reduced, and the contrast ratio of the display panel 10 is improved. Specifically, the orthographic projection of the filter function portion 51 on the array substrate 1 covers at least part of the orthographic projection of the isolation structure on the array substrate 1, thereby reducing the incidence amount of the external light irradiated to the isolation structure 3 on the side surface facing away from the array substrate 1 by covering the isolation structure 3 with the filter function portion 51. The light rays emitted to the direction of the isolation structure 3 are firstly incident to the part of the optical filtering function part 51 opposite to the isolation structure 3, the light rays with different colors from the optical filtering function part 51 are filtered by the optical filtering function part 51, and the light rays incident into the optical filtering function part 51 are refracted, scattered and the like, so that the incident quantity of the light rays incident into the isolation structure 3, which is far away from the surface of one side of the array substrate 1, is greatly reduced, the light ray reflection quantity of the isolation structure 3 is reduced, and the contrast of the display panel 10 is improved. Meanwhile, the light transmittance of the filter layer 5 is high, and the contrast ratio of the display panel 10 is improved, and meanwhile, the light emitting rate of the display panel 10 can be ensured, so that the low power consumption of the display panel 10 is ensured.

In the above embodiment, the orthographic projection of the filter function portion 51 on the array substrate 1 covers the orthographic projection of the light emitting unit 40 on the array substrate 1.

In the display panel 10 provided by the application, the filter layer 5 is arranged on one side of the light emitting unit 40 away from the array substrate 1, so that the light emitting purity of the light emitting unit 40 can be improved, and the display effect can be improved.

In a possible embodiment, the isolation structure 3 comprises a first layer 31 and a second layer 32 arranged in a stacked manner in a direction away from the array substrate 1, and the orthographic projection of the first layer 31 on the array substrate 1 is located within the orthographic projection of the second layer 32 on the array substrate 1.

In the above embodiment, the isolation structure 3 is formed on one side of the array substrate 1, the isolation structure 3 includes the first layer 31 and the second layer 32 stacked in a direction away from the array substrate 1, the orthographic projection of the first layer 31 on the array substrate 1 is located in the orthographic projection of the second layer 32 on the array substrate 1, so that a step portion is formed between the second layer 32 and the first layer 31, the second electrode 43 and the light-emitting functional layer 42 in the light-emitting layer 4 are separated at the step portion through the step portion, so that adjacent light-emitting units 40 are mutually independent, so that each light-emitting unit 40 is driven independently, thereby helping to achieve the purpose of reducing the power consumption of the display panel 10. Meanwhile, the display panel is matched with the filter layer 5 to realize the filtering of light, a polaroid structure is not arranged, and compared with a display panel with a conventional polaroid, the light transmittance of the filter layer 5 is higher, the contrast ratio of the display panel 10 is improved, the light emitting rate of the display panel 10 is ensured, and therefore the low power consumption of the display panel 10 is ensured.

In a possible embodiment, the display panel further includes a pixel defining layer 2, and the pixel defining layer 2 is formed on one side of the array substrate 1 and includes a plurality of pixel openings 21. The front projection of the pixel opening 21 on the array substrate 1 coincides with the front projection of the isolation opening 30 on the substrate 1. The isolation structures 3 are arranged on the side of the pixel defining layer 2 facing away from the array substrate 1, and the orthographic projection of the isolation structures 3 on the pixel defining layer 2 is located between adjacent pixel openings 21. In other embodiments, the isolation structure 3 may also be directly disposed on one side of the array substrate 1, which is not limited in particular.

In the above embodiment, the orthographic projection of the isolation structure 3 on the pixel defining layer 2 is located between the adjacent pixel openings 21, so that the shielding of the isolation structure 3 on the light emitted by the light emitting unit 40 in the pixel opening 21, especially the shielding of the light emitting unit 40 with a large angle, can be reduced, and the brightness of the display panel can be improved, and the power consumption can be further saved.

In the display panel 10 provided by the application, the isolation structure 3 is arranged between the adjacent pixel openings 21, so that the light-emitting functional layer 42 in the adjacent pixel opening 21 is disconnected at the isolation structure, thereby reducing the probability of mutual crosstalk between the adjacent light-emitting units 40 and being beneficial to further improving the display effect.

In a possible embodiment, the material of the isolation structure 3 is metal, and the material of the pixel defining layer 2 is an inorganic material.

In the above embodiment, the material of the isolation structure 3 is metal, so that the second electrodes 43 between the adjacent light emitting units 40 can be electrically connected, so that the number of power supply lines to the second electrodes 43 in the display panel 10 is reduced, and thus, the wiring in the display panel 10 is simplified and the manufacturing cost is reduced. Meanwhile, the isolation structure 3 is provided at a side of the pixel defining layer 2 facing away from the substrate, and when preparing the light emitting units 40 of various colors, each film layer in the light emitting units 40 of one color is formed over the whole surface, and then the light emitting units 40 of the one color are formed at the designated pixel openings 21 by etching, and the pixel openings 21 for forming the light emitting units 40 of the other colors are exposed. The light emitting units 40 with different colors are prepared for multiple times, a mask plate is not required to be used in the preparation process, and a support column is not required to be arranged on one side of the pixel definition layer 2, which is away from the array substrate 1, so that the preparation cost can be saved. The isolation structure 3 may be formed of a dark material, so that a light shielding effect may be achieved, and a probability of lateral crosstalk between adjacent light emitting units 40 may be reduced. And in the thickness direction of the display panel, light rays below the isolation structure 3 are shielded, so that the light rays are prevented from being emitted by the light emitting surface, and the light rays below the isolation structure 3 specifically comprise scattered light and the like in the pixel definition layer 2 and the inner film layer of the array substrate 1. At this time, the pixel defining layer 2 may be made of a light-transmitting inorganic material to further reduce the material cost.

In a possible embodiment, the orthographic projection of the optical filtering function portion 51 on the array substrate 1 covers at least a portion of the orthographic projection of the isolation structure 3 on the array substrate 1, so that a portion of the light emitted to the isolation structure 3 can be filtered by the optical filtering function layer, so as to reduce the reflection amount of the isolation structure 3 on the light.

In a possible embodiment, as shown in fig. 3, the orthographic projection of the filter function portion 51 on the array substrate 1 covers the orthographic projection of the isolation structure 3 on the array substrate 1.

Specifically, the orthographic projections of the adjacent filter function parts 51 on the array substrate 1 overlap to form an overlapping region, and the orthographic projection of the overlapping region on the array substrate 1 covers the orthographic projection of the partial second layer 32 on the array substrate 1, so that the orthographic projection of the filter function parts 51 on the array substrate 1 covers the orthographic projection of the isolation structure 3 on the array substrate 1. Or the orthographic projection of the filter function part 51 on the array substrate 1 covers the orthographic projection of the isolation structure 3 on the array substrate 1, and the orthographic projections of the adjacent filter function parts 51 on the array substrate 1 are staggered.

In the above embodiment, when the isolation structure 3 is made of a material that is easily reflective, such as metal, the amount of incident external light that irradiates the isolation structure 3 on the side surface facing away from the array substrate 1 can be reduced by covering the isolation structure 3 with the light filtering function portion 51. Specifically, the light beam directed to the direction of the isolation structure 3 is first incident on the portion of the optical filtering function portion 51 opposite to the isolation structure 3, the light beam having a color different from that of the optical filtering function portion 51 is filtered by the optical filtering function portion 51, and the light beam incident into the optical filtering function portion 51 is refracted, scattered, and the like, so that the incident amount of the light beam incident into the isolation structure 3 facing away from the surface of the array substrate 1 is greatly reduced, the light reflection amount of the isolation structure 3 is reduced, and the contrast of the display panel 10 is improved.

In one possible embodiment, as shown in fig. 3, the orthographic projections of the adjacent filter function parts 51 on the array substrate 1 overlap to form an overlapping region, and the orthographic projection of the overlapping region on the array substrate 1 covers the orthographic projection of the second layer 32 on the array substrate 1 along the center of the arrangement direction of the adjacent filter function parts 51.

In the above embodiment, the isolation structure 3 is covered by the optical filter function portions 51 located at two sides of the isolation structure 3, so that the optical filter function portions 51 located at two sides of the isolation structure 3 can be guaranteed to well cover the light emitting units 40 located at two sides of the isolation structure 3, so that the light emitted by the light emitting units 40 is emitted after being filtered by the optical filter function portions 51, and the light emitting purity of the light emitting units 40 can be guaranteed. Meanwhile, the orthographic projection of the overlapping area on the array substrate 1 covers the orthographic projection of the second layer 32 on the array substrate 1 along the center of the arrangement direction of the adjacent filter function parts 51, so that the coverage of different filter function parts 51 to the isolation structure 3 is close and larger, and compared with the scheme that one filter function part 51 has smaller coverage and only covers the edge of the isolation structure 3, and the other filter function part 51 has larger coverage, the preparation precision of each filter function part 51 in the preparation process is better controlled, and the preparation yield is improved.

Specifically, in the overlapping region formed by overlapping orthographic projections of the adjacent filter function portions 51 on the array substrate 1, one of the filter function portions 51 is gradually thinned in an edge region, and in a cross section of the filter function portion 51 along the thickness direction of the array substrate 1, a side edge facing away from the array substrate 1 may include a first edge line L1 parallel to the array substrate and a second edge line L2 connected to the first edge line L1, and the second edge line L2 may be a straight line, and disposed obliquely to a plane in which the array substrate 1 is located, or be an arc line, which is not particularly limited in the present application. The edge area of the other filter function portion 51 may cover the edge area of the filter function portion 51, specifically, in a cross section along the thickness direction of the array substrate 1 in the other filter function portion 5, a side edge facing away from the array substrate 1 may include a third edge line L3 parallel to the array substrate and a fourth edge line L4 connected to the third edge line L3, and the fourth edge line L4 may be a straight line and disposed obliquely to the plane of the array substrate 1 or be an arc line, which is not particularly limited in the present application. In the cross section of the filter layer along the thickness direction of the array substrate 1, in two adjacent filter functional portions 51, the fourth edge line L4 may contact with the second edge line L3, so that the surface of the overlapping region on the side facing away from the array substrate 1 is lower than the surface of the other region on the side facing away from the array substrate 1.

In a possible embodiment, as shown in fig. 3, the display panel 10 further includes an encapsulation layer 6, where the encapsulation layer 6 is formed on a side of the light emitting layer 4 facing away from the array substrate 1, the encapsulation layer 6 includes a first encapsulation layer 61, a second encapsulation layer 62, and a third encapsulation layer 63 stacked in a direction away from the substrate, and the optical filter layer 5 is disposed in the encapsulation layer 6, or the optical filter layer 5 is disposed on a side of the encapsulation layer 6 facing away from the array substrate 1 and is disposed adjacent to the encapsulation layer 6.

The second encapsulation layer 62 is made of an organic material, and the organic material has high flexibility and flatness. By arranging the optical filter layer 5 between the first encapsulation layer 61 and the second encapsulation layer 62, on one hand, the optical filter layer 5 is arranged on one side of the first encapsulation layer 61 away from the light emitting unit 40, so that the first encapsulation layer 61 is in direct contact with the light emitting unit 40, and the encapsulation effect of the first encapsulation layer 61 on the light emitting unit 40 can be ensured not to be interfered by the optical filter layer 5. On the other hand, the second encapsulation layer 62 is disposed on a side of the optical filter layer 5 away from the array substrate 1, and the surface of the side of the optical filter layer 5 away from the substrate can be flattened by the second encapsulation layer 62, so as to facilitate the contact effect between the second encapsulation layer 62 and the third encapsulation layer 63, thereby helping to promote the sealing effect of the third encapsulation layer 63.

Meanwhile, the filter layer 5 is arranged in the packaging layer 6, so that the distance between the filter layer 5 and the pixel opening 21 of the pixel definition layer 2 is smaller, the alignment of the filter function part 51 and the light emitting unit 40 positioned in the pixel opening 21 is facilitated, and the alignment precision of the filter function part 51 and the light emitting unit 40 is higher.
