[0068] The features and exemplary embodiments of various aspects of this application will now be described in detail. Numerous specific details are set forth in the following detailed description to provide a comprehensive understanding of this application. However, it will be apparent to those skilled in the art that this application can be implemented without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of this application by illustrating examples. In the accompanying drawings and the following description, at least some well-known structures and techniques are not shown to avoid unnecessarily obscuring the application; and, for clarity, the dimensions of some structures may be exaggerated. Furthermore, the features, structures, or characteristics described below can be combined in any suitable manner in one or more embodiments.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0070] The directional terms appearing in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of the embodiments of this application. It should also be noted in the description of this application that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0071] like Figure 1 and Figure 2a As shown, a display panel provided in the first aspect embodiment of this application includes: a substrate 100, an isolation structure 200, a light-emitting layer, a first planarization layer 410, and a filter layer 500. The isolation structure 200 is disposed on one side of the substrate 100, and the isolation structure 200 encloses an isolation opening 240. The light-emitting layer includes light-emitting units 300 disposed within the isolation opening 240. The first planarization layer 410 is disposed on the side of the light-emitting layer opposite to the substrate 100. The filter layer 500 is disposed on the side of the first planarization layer 410 opposite to the substrate 100.

[0072] In this embodiment, the isolation structure 200 encloses an isolation opening 240, and the light-emitting unit 300 is disposed within the isolation opening 240. The isolation structure 200 can reduce light crosstalk between adjacent light-emitting units 300, thereby improving the display effect of the display panel. The first planarization layer 410 is disposed on the side of the light-emitting layer away from the substrate 100 to planarize the step difference between the light-emitting layer and the isolation structure 200, thereby facilitating the fabrication of the filter layer 500. The filter layer 500 is disposed on the side of the first planarization layer 410 away from the substrate 100, and the filter layer 500 can filter the emitted light from the light-emitting unit 300, thereby improving the display effect of the display panel.

[0073] In some embodiments, the side of the light-emitting layer facing away from the substrate 100 is planarized using an organic material printed by inkjet printing. The thickness of the organic material in the middle is greater than that at the edges, creating a height difference. This affects the thickness of the filter layer 500 during subsequent fabrication, causing uneven thickness and affecting the filtering effect. In this application, a first planarization layer 410 is used to planarize the side of the light-emitting layer facing away from the substrate 100. The height difference between the middle and edge portions of the first planarization layer 410 is smaller, resulting in better thickness uniformity of the filter layer 500 and improving the performance of the display panel.

[0074] Furthermore, by placing the filter layer 500 on the first planarization layer 410, the distance between the filter layer 500 and the light-emitting layer can be reduced.

[0075] The substrate 100 can be configured in various ways. The substrate 100 may include a substrate and a first conductive layer, a second conductive layer, and a third conductive layer stacked on one side of the substrate. An insulating layer is disposed between adjacent conductive layers. For example, a pixel driving circuit is disposed on the substrate 100. The pixel driving circuit includes a transistor and a storage capacitor. The transistor includes a semiconductor, a gate, a source, and a drain. The storage capacitor includes a first electrode and a second electrode. As an example, the gate and the first electrode may be located on the first conductive layer, the second electrode may be located on the second conductive layer, and the source and drain may be located on the third conductive layer.

[0076] Optionally, the material of the first planarization layer 410 may include optical adhesive, which gives the first planarization layer 410 good flowability and enables it to better planarize the step difference between the light-emitting layer and the isolation structure 200.

[0077] like Figures 1 to 3 As shown, in some optional embodiments, the display panel has a display area AA and a barrier area 110 surrounding the display area AA, the barrier area 110 being disposed on one side of the substrate 100; a first planarization layer 410 is located within the area enclosed by the barrier area 110, the first planarization layer 410 includes a first region 411 and a second region 412, the second region 412 being located between the first region 411 and the barrier area 110, the first planarization layer 410 including a first surface 413 on the side facing away from the substrate 100, the first surface 413 located in the second region 412 being disposed at equal intervals with the substrate 100.

[0078] In these alternative embodiments, the second region 412 is disposed around the first region 411, and the barrier region 110 is disposed around the second region 412 on the side away from the first region 411. In the second region 412, the first surface 413 of the first planarization layer 410 is spaced equidistant from the substrate 100, and the side of the first planarization layer 410 away from the substrate 100 is parallel to the plane of the substrate 100. The filter layer 500 is disposed on one side of the first surface 413.

[0079] The barrier area 110 includes a plurality of dams disposed on one side of the substrate 100. The height of the dams from the plane where the substrate 100 is located is greater than or equal to the height of the first planarization layer 410 from the plane where the substrate 100 is located. Each dam surrounds at least one side of the display area AA, and the plurality of dams are arranged sequentially along a plane parallel to the plane where the substrate 100 is located.

[0080] In some embodiments, the thickness of the organic material varies significantly in the second region 412 on the side of the light-emitting layer away from the substrate 100 through self-leveling. That is, the organic material is thinner closer to the barrier region 110, thus affecting the thickness uniformity of the filter layer 500. In this embodiment, the first surface 413 of the first planarization layer 410 in the second region 412 is evenly spaced from the substrate 100, such as... Figure 3 In the second region 412, the distance between the first surface 413 of the first planarization layer 410 and the substrate 100 is B, so that the first surface 413 of the first planarization layer 410 in the second region 412 facing away from the substrate 100 can be planarized, thereby improving the thickness uniformity of the filter layer 500.

[0081] Optionally, the distances from the first surface 413 located in the first region 411 and the first surface 413 located in the second region 412 to the substrate 100 are equal, thereby improving the ability of the first surface 413 in the first region 411 and the first surface 413 in the second region 412 to be on the same plane, and further improving the thickness uniformity of the filter layer 500 in the first region 411 and the filter layer 500 in the second region 412, such as... Figure 3 In the first region 411, the distance between the first surface 413 of the first planarization layer 410 and the substrate 100 is b, where B = b.

[0082] like Figure 2a As shown, in some alternative embodiments, the first planarization layer 410 covers the side of the light-emitting unit 300 away from the substrate 100 and fills the isolation opening 240.

[0083] In these alternative embodiments, the first planarization layer 410 fills the isolation opening 240 and covers the side of the light-emitting unit 300 away from the substrate 100, thereby planarizing the isolation structure 200 and the side of the light-emitting unit 300 away from the substrate 100.

[0084] Optional, such as Figure 2a As shown, the first planarization layer 410 also covers the side of the isolation structure 200 away from the substrate 100. The distance D from the first surface 413 of the first planarization layer 410 away from the substrate 100 to the substrate 100 is greater than the distance d from the side of the isolation structure 200 away from the substrate 100 to the substrate 100. That is, the first planarization layer 410 covers the isolation opening 240 and the isolation structure 200, so that the filter layer 500 can be completely fabricated on the first surface 413, reducing the influence of the isolation structure 200 on the filter layer 500.

[0085] like Figure 2a As shown, in some optional embodiments, the display panel includes a first encapsulation layer, the first encapsulation layer including an encapsulation portion 420 disposed on the side of the light-emitting unit 300 away from the substrate 100, the encapsulation portion 420 extending from the isolation opening 240 to the side of the isolation structure 200 away from the substrate 100, and a first planarization layer 410 disposed on the side of the encapsulation portion 420 away from the substrate 100.

[0086] In these alternative embodiments, the encapsulation portion 420 can encapsulate the light-emitting unit 300, reducing the entry of water, oxygen, etc., into the light-emitting unit 300 and affecting its service life. The encapsulation portion 420 extends from the isolation opening 240 to the side of the isolation structure 200 away from the substrate 100, thereby improving the encapsulation effect of the encapsulation portion 420.

[0087] like Figure 2a As shown, in some optional embodiments, a sealing gap 421 is formed between two adjacent encapsulation portions 420 on the side of the isolation structure 200 away from the substrate 100, and a portion of the first planarization layer 410 is located in the sealing gap 421 and is disposed in contact with the isolation structure 200.

[0088] In these optional embodiments, each light-emitting unit 300 has an encapsulation portion 420 on the side facing away from the substrate 100. Adjacent encapsulation portions 420 are spaced apart or partially in contact. Adjacent encapsulation portions 420 have a sealing gap 421 on the side of the isolation structure 200 facing away from the substrate 100, ensuring that the light-emitting unit 300 on the side of the isolation structure 200 facing away from the substrate 100 is removed. A portion of the first planarization layer 410 is located in the sealing gap 421 and is in contact with the isolation structure 200 to fill the sealing gap 421.

[0089] like Figure 2a As shown, in some optional embodiments, the isolation structure 200 includes a first sublayer 210 and a second sublayer 220, the first sublayer 210 being located on the side of the second sublayer 220 facing the substrate 100, and the orthographic projection of the first sublayer 210 on the substrate 100 being within the orthographic projection of the second sublayer 220 on the substrate 100.

[0090] In these optional embodiments, the orthographic projection size of the first sublayer 210 on the substrate 100 is smaller than the orthographic projection size of the second sublayer 220 on the substrate 100, so as to form a recess under the second sublayer 220. During the fabrication of the light-emitting unit 300, the material of the light-emitting unit 300 can be separated into mutually independent light-emitting structures 320 by the isolation structure 200, which can eliminate the need for a precision mask evaporation process, thereby reducing fabrication costs. Optionally, the orthographic projection area of ​​the first sublayer 210 on the substrate 100 is smaller than the orthographic projection area of ​​the second sublayer 220 on the substrate 100.

[0091] Optional, such as Figure 2a As shown, a portion of the first planarization layer 410 fills the side of the second sublayer 220 facing the substrate 100. The first planarization layer 410 fills the isolation opening 240 and extends to the side of the second sublayer 220 facing the substrate 100, so that the first planarization layer 410 completely fills the isolation opening 240, thereby improving the planarization effect of the first planarization layer 410.

[0092] Optional, such as Figure 2aAs shown, the isolation structure 200 also includes a third sub-layer 230, which is disposed on the side of the first sub-layer 210 facing the substrate 100. The orthographic projection of the first sub-layer 210 on the substrate 100 lies within the orthographic projection of the third sub-layer 230 on the substrate 100. When the first sub-layer 210 is etched to form, the third sub-layer 230 is less affected by etching and can provide better protection to the substrate 100.
