In the prior art, a conductive enclosure structure is introduced to improve the pixel resolution of the display panel. The conductive enclosure structure comprises an insulating part and a conductive part overlapped with the cathode. The conductive part is used for being electrically connected with the cathode of the sub-pixel so as to realize the net connection of the cathode, and the conductive part is matched with the cathode to form the whole connection of the cathode.

However, since the insulating portion is disposed on the upper surface of the conductive portion, and the projected area of the insulating portion is larger than that of the conductive portion, the reliability and uniformity of the overlap joint between the cathode and the conductive portion may be improved; secondly, because of eave structural design of the insulating part, the thickness of the etching protection layer covering the sub-pixels and the conductive enclosure structure is uneven, and therefore the effect of preventing external water vapor cannot be well achieved. Although this problem can be solved by increasing the thickness of the etching resist, it results in an increase in production time and production cost, and a decrease in the amount of light emitted from the sub-pixels, while also exacerbating the risk of breakage of the etching resist. It can be seen that the arrangement of the conductive enclosure structure can lead to a great threat to the yield and stability of the product.

The application provides a display panel and a display device, so as to solve the technical problems. The display panel provided in the present application will be described in detail.

The pixel defining layer 10 has a plurality of pixel openings 11 arranged at intervals. The plurality of sub-pixels 20 are disposed in the pixel opening 11 in a one-to-one correspondence. The plurality of sub-pixels 20 are sequentially arranged in the first direction D1 and the second direction D2, respectively.

The first direction D1, the second direction D2 and the third direction D3 are located in the same plane, and an included angle between the first direction D1 and the second direction D2 is greater than an included angle between the first direction D1 and the third direction D3, and is greater than an included angle between the second direction D2 and the third direction D3. Conductive enclosure structures 30 are disposed protruding from the pixel defining layer 10 and surrounding the pixel groups 24. The cathodes 23 of the sub-pixels 20 in the pixel group 24 are connected by the conductive barrier structure 30. Wherein the number of sub-pixels 20 included in part of the pixel group 24 is different.

This application is with a plurality of sub-pixels 20 respectively in order arrangement and make the sub-pixel 20 of the same colour arrange in order in first direction D1 and second direction D2 in order to form pixel group 24 in third direction D3 to make electrically conductive enclosing structure 30 enclose and establish pixel group 24 setting, make need not to set up electrically conductive enclosing structure 30 between the sub-pixel 20 in the pixel group 24, can reduce the quantity of electrically conductive enclosing structure 30 in the display panel, thereby reduce the overlap joint bad problem between the cathode 23 of sub-pixel 20 and the electrically conductive enclosing structure 30, and reduce the influence to other layers of film that cover sub-pixel 20 and electrically conductive enclosing structure 30, and then promote display panel's product yield and stability.

The pixel definition layer 10 defines the locations of the sub-pixels 20. The pixel defining layer 10 is provided with a plurality of pixel openings 11 arranged at intervals, and the pixel openings 11 are arranged in one-to-one correspondence with the sub-pixels 20. That is, one sub-pixel 20 is disposed in one pixel opening 11.

The thickness of the pixel defining layer 10 and the material of the pixel defining layer 10 are not limited herein, and are selected according to practical requirements.

The sub-pixel 20 includes an anode 21, a light emitting layer 22, and a cathode 23, which are stacked in this order from bottom to top. The light emitting layer 22 includes a hole injection layer, a hole transport layer, an electron blocking layer, a light emitting material layer, a hole blocking layer, an electron injection layer, an electron transport layer, and the like. The structure of the light emitting layer 22 is not limited here, and is selected according to actual needs. One subpixel 20 corresponds to one color. The color, shape and size of the sub-pixels 20 are not limited, and are selected according to practical requirements.

In the present embodiment, the plurality of sub-pixels 20 of different colors are the first pixel 201, the second pixel 202, and the third pixel 203, respectively. That is, the present application includes three different colored subpixels 20. The first pixel 201, the second pixel 202, and the third pixel 203 are a blue pixel, a red pixel, and a green pixel, respectively, in this order. The sub-pixels 20 are rectangular.

It should be appreciated that the first pixel 201, the second pixel 202 and the third pixel 203 may be other color combinations as well. For example, the first pixel 201, the second pixel 202, and the third pixel 203 are a red pixel, a blue pixel, and a green pixel, respectively, in this order. The first pixel 201, the second pixel 202, and the third pixel 203 may also be other color pixels. The present application may also include two, four or more color pixels.

The conductive enclosure structure 30 protrudes from the pixel defining layer 10, and encloses to form a pixel accommodating area 310. The pixel accommodating area 310 is used for accommodating the pixel group 24.

The single pixel group 24 includes at least one sub-pixel 20. One pixel group 24 is disposed in one pixel accommodating area 310, and the number of sub-pixels 20 included in part of the pixel group 24 is different. That is, one conductive enclosure structure 30 encloses one pixel group 24, and not all the pixel groups 24 include the same number of sub-pixels 20.

The spacing between adjacent sub-pixels 20 in the third direction D3 within the pixel group 24 is not limited herein, and is selected according to practical requirements.

As shown in fig. 4, when the pixel group 24 in the conductive enclosure structure 30 includes a plurality of sub-pixels 20, the organic light emitting layers 22 of two adjacent sub-pixels 20 in the pixel group 24 are disposed in contact with each other and cover the pixel defining layer 10 between the two adjacent sub-pixels 20. Similarly, when the pixel group 24 in the conductive enclosure structure 30 includes a plurality of sub-pixels 20, the cathodes 23 of two adjacent sub-pixels 20 in the pixel group 24 are disposed in contact with each other and cover the pixel defining layer 10 between the two adjacent sub-pixels 20.

Specifically, an end of the conductive enclosure structure 30 in the third direction D3 is defined as a short-side end of the conductive enclosure structure 30. When the pixel group 24 in the conductive enclosure structure 30 includes two sub-pixels 20, one end of the organic light emitting layer 22 of one sub-pixel 20 of the two sub-pixels 20 extends to be disposed in contact with the short side end of the conductive enclosure structure 30, and the other end is disposed in contact with the organic light emitting layer 22 of the adjacent sub-pixel 20 and covers the pixel defining layer 10 between the two sub-pixels 20. When the pixel group 24 in the conductive enclosure structure 30 includes three or more sub-pixels 20, the sub-pixels 20 located at the short side end of the conductive enclosure structure 30 are defined as end sub-pixels 241, and the remaining sub-pixels 20 in the pixel group 24 except for the end sub-pixels 241 are defined as middle sub-pixels 242. One end of the organic light emitting layer 22 of the end sub-pixel 241 extends to be in contact with the short side end of the conductive enclosure structure 30, and the other end is in contact with the organic light emitting layer 22 of the adjacent intermediate sub-pixel 242 and covers the pixel defining layer 10 between the end sub-pixel 241 and the adjacent intermediate sub-pixel 242. The organic light emitting layers 22 of the intermediate sub-pixels 242 are disposed in contact with each other and cover the pixel defining layer 10 between the end sub-pixels 241.

This application sets up the pixel group 24 in the pixel accommodation area 310 that electrically conductive fender structure 30 encloses to be established for do not set up electrically conductive fender structure 30 between the adjacent sub-pixel 20 that sets up along third direction D3 in the pixel group 24, in order to reduce the quantity that electrically conductive fender structure 30 in the display panel, thereby reduce the negative pole 23 of sub-pixel 20 and electrically conductive overlap joint bad problem between the fender structure 30, and reduce the influence to other covering sub-pixel 20 and electrically conductive rete that encloses fender structure 30, and then promote display panel's product yield and stability.

Further, the arrangement order of the plurality of sub-pixels 20 in the first direction D1 is different from the arrangement order of the plurality of sub-pixels 20 in the second direction D2. The arrangement is such that the same color sub-pixels 20 can be arranged in a row in the third direction D3.

The arrangement order of the plurality of different color sub-pixels 20 in the first direction D1 or the second direction D2 is related to the color type of the sub-pixels 20 included in the present application.

In the present embodiment, the first pixels 201, the second pixels 202, and the third pixels 203 are alternately arranged in the first direction D1 in order, and the first pixels 201, the third pixels 203, and the second pixels 202 are alternately arranged in the second direction D2 in order. The first direction D1 is arranged perpendicular to the second direction D2.

It should be appreciated that in other embodiments, the first direction D1 and the second direction D2 may be disposed non-perpendicularly.

The conductive enclosure structure 30 includes a conductive portion 31 and an insulating portion 32 that is located on an upper surface of the conductive portion 31 and shields the conductive portion 31. The insulating portion 32 extends out of the conductive portion 31 in a direction parallel to the pixel defining layer 10 and toward a direction away from the conductive portion 31. The cathode 23 of the sub-pixel 20 is in contact with and is electrically connected to the conductive portion 31 of the corresponding conductive barrier structure 30. That is, the orthographic projection area of the insulating portion 32 on the pixel defining layer 10 is larger than the orthographic projection area of the conductive portion 31 on the pixel defining layer 10, so that when the sub-pixel 20 is evaporated, the evaporation angle of the cathode 23 and the light emitting layer 22 can be adjusted by the insulating portion 32, so as to ensure that the cathode 23 covers the light emitting layer 22 and forms good lap joint with the conductive portion 31.

The side wall of the insulating portion 32 may be a plane or a curved surface, and is not limited in this way, and is selected according to practical requirements.

In the present embodiment, the side wall of the insulating portion 32 is planar, facilitating the preparation of the insulating portion 32.

Further, the spacing between the sub-pixel 20 and the sidewall of the insulating portion 32 of the conductive enclosure structure 30 where the sub-pixel 20 is located is greater than 3 microns. That is, the spacing between the pixel opening 11 and the sidewall of the insulating portion 32 of the adjacent conductive enclosure structure 30 is greater than 3 micrometers.

The distance between the two opposite side walls of the conductive enclosure structure 30 is greater than 3 micrometers, so as to avoid the problem that the number of the conductive enclosure structures 30 is increased due to contact between the two opposite side walls of the conductive enclosure structure 30, which results in poor overlap joint between the cathode 23 of the sub-pixel 20 and the conductive enclosure structure 30.

In the present embodiment, in the first direction D1, the centers of the plurality of sub-pixels 20 of different colors and alternately arranged are on the same straight line, and the centers of the sub-pixels 20 included in each pixel group 24 are on the same straight line. The arrangement of the sub-pixels 20 is beneficial to uniformity of display brightness, so as to improve display image quality.

It should be understood that the centers of the plurality of differently colored and alternately arranged sub-pixels 20 may not be located on the same straight line in the first direction D1. In other embodiments, a plurality of sub-pixels 20 of different colors and alternately arranged are aligned in the first direction D1 along one end of the second direction D2. That is, one end portions of the plurality of sub-pixels 20 of different colors and alternately arranged are located on the same horizontal plane in the second direction D2.

Further, in the fourth direction D4, the number of sub-pixels 20 included in the pixel group 24 located in the middle area of the display panel is greater than the number of sub-pixels 20 included in the pixel group 24 located in the edge area of the display panel. The fourth direction D4 is located on the same plane as the first direction D1, the second direction D2, and the third direction D3. The fourth direction D4 is disposed to intersect the first direction D1 and the second direction D2, respectively, and is perpendicular to the third direction D3. The design mode ensures that the area of the display panel can be approximately a rectangular area so as to be suitable for most display devices and improve the application range of the display panel.

In this embodiment, the edge of the display area of the display panel is saw-toothed. The conductive enclosure structure 30 is a rectangular annular structure. The light emitting area of the first pixel 201, the light emitting area of the second pixel 202, and the light emitting area of the third pixel 203 are different. The extending direction of the sub-pixels 20 is parallel to the third direction D3 to reduce the interval between adjacent sub-pixels 20 in the pixel group 24 in the third direction D3, thereby improving the pixel aperture ratio. Here, the included angle between the third direction D3 and the second direction D2 is not limited, and is selected according to actual requirements. For example, the included angle between the third direction D3 and the second direction D2 may be 60 degrees, 45 degrees, or 30 degrees.

The present application further includes a driving substrate 40, where the driving substrate 40 is used to drive the sub-pixels 20 to emit light. The driving substrate 40 is disposed on a side of the pixel defining layer 10 away from the conductive enclosure structure 30, where the structure of the driving substrate 40 is not limited and is selected according to practical requirements.

The second embodiment of the display panel provided in the present application is substantially similar to the first embodiment of the display panel provided in the present application in structure, except that: the light emitting area of the first pixel 201, the light emitting area of the second pixel 202, and the light emitting area of the third pixel 203 are all the same.

In this embodiment, the light emitting area of the first pixel 201, the light emitting area of the second pixel 202, and the light emitting area of the third pixel 203 are all the same. The sub-pixels 20 are arranged in a matrix. The first direction D1 is perpendicular to the second direction D2. The conductive enclosure structure 30 is a ring-shaped structure. The side wall of the insulating portion 32 of the conductive enclosure structure 30 is curved. On a plane parallel to the pixel defining layer 10, the sidewalls of the conductive barrier structure 30 undulate, facilitating the deposition and coverage of subsequent layers and the overlap of the cathode 23 and the conductive portion 31.

It should be appreciated that the shape and arrangement of the sub-pixels 20 determines the shape of the side walls of the insulating portion 32 of the conductive enclosure structure 30.

Compared with the first embodiment of the display panel provided by the application, the number of the conductive enclosure structures 30 in the display panel can be reduced, so that the problem of poor overlap joint between the cathode 23 of the sub-pixel 20 and the conductive enclosure structures 30 is reduced, the influence on other film layers covering the sub-pixel 20 and the conductive enclosure structures 30 is reduced, and the product yield and stability of the display panel are improved.
