[0042] It should be noted that, in the absence of conflict, different features in the embodiments of the present application may be combined with each other.

[0043] See also Figure 1In some display panels, such as Mini LED or Micro-LED display panels, at least one light-emitting unit 400' is bonded to one side of the driving backplane 100'. In order to reduce the reflection of the exposed driving backplane 100' between the light-emitting units 400' to the external light, a light shielding layer 600' is provided between the light-emitting units 400'. However, the light shielding layer 600' will cover the side wall of the light-emitting unit 400', causing the light emitted from the side wall of the light-emitting unit 400' to be absorbed by the light shielding layer 600' and unable to be emitted, thereby reducing the light output rate of the light-emitting panel.

[0044] In view of this, the present embodiment provides a solution that can improve the light extraction efficiency of the display panel. The solution provided by the present embodiment is described in detail below.

[0045] Please refer to Figure 2 , Figure 2 The cross-sectional schematic diagram of a display panel provided in the present embodiment along its thickness direction, the display panel may include a driving backplane 100 , at least one light-emitting unit 400 , a light-transmitting structure 500 and a light-shielding layer 600 .

[0046] The driving backplane 100 may include a thin film transistor (TFT) array backplane, and a plurality of electrodes for bonding with the light emitting unit 400 may be disposed on one side of the driving backplane 100 .

[0047] The light emitting unit 400 is located at one side of the driving backplane 100 and is electrically connected to the driving backplane 100. For example, the light emitting power source 400 can be bonded to the bonding electrode on the driving backplane 100.

[0048] The light-transmitting structure 500 is located on one side of the driving backplane 100 and surrounds at least a portion of the light-emitting unit 400. That is, in this embodiment, the light-transmitting structure 500 may cover at least a portion of the side of the light-emitting unit 400. Optionally, in this embodiment, the light-transmitting structure 500 may be disposed after bonding the light-emitting unit 400. The material of the light-transmitting structure 500 may include but is not limited to transparent photoresist.

[0049] The light shielding layer 600 is located on one side of the driving backplane 100, and the light shielding layer 600 includes a pixel opening that exposes the light emitting unit 400 and at least a portion of the light-transmitting structure 500. That is, in this embodiment, in a direction parallel to the driving backplane 100, at least a portion of the light-transmitting structure 500 may be located between the light emitting unit 400 and the light shielding layer 600.

[0050] Based on the above design, by providing the light-transmitting structure 500 surrounding at least a portion of the light-emitting unit 400, a certain interval is provided between the side wall of the light-emitting unit 400 and the light-shielding layer 600. In this way, the light-shielding layer 600 can be prevented from directly shielding the side wall of the light-emitting unit 400, so that the light emitted from the side of the light-emitting unit 400 can also be emitted through the light-transmitting structure 500, thereby improving the light extraction rate of the display panel.

[0051] Please refer to Figure 3 The display panel provided in this embodiment may further include an anisotropic conductive film 200. The anisotropic conductive film 200 is located on one side of the driving backplane 100 and is used to realize electrical connection between the light emitting unit 400 and the electrodes on the driving backplane 100.

[0052] The light-emitting unit 400 is embedded in the anisotropic conductive film 200 and is electrically connected to the driving backplane 100 through the anisotropic conductive film 200. The light-emitting unit 400 may include a bonding portion embedded in the anisotropic conductive film 200 and a light-emitting portion protruding from the anisotropic conductive film 200. The side of the light-emitting portion away from the driving backplane 100 may be the top surface of the light-emitting portion, and the other exposed surfaces of the light-emitting portion may be the side surfaces of the light-emitting portion.

[0053] The light-transmitting structure 500 is located on a side of the anisotropic conductive adhesive film 200 away from the driving backplane 100 and surrounds at least a portion of the light-emitting portion. That is, in this embodiment, the light-transmitting structure 500 can cover at least a portion of the side of the light-emitting portion. Optionally, in this embodiment, the light-transmitting structure 500 can be arranged after the light-emitting unit 400 is bonded. The material of the light-transmitting structure 500 can include but is not limited to light-transmitting photoresist.

[0054] The light shielding layer 600 is located on a side of the anisotropic conductive adhesive film 200 away from the driving backplane 100, and the light shielding layer 600 includes a pixel opening exposing the light emitting portion and at least a portion of the light-transmitting structure 500. That is, in this embodiment, in a direction parallel to the driving backplane 100, at least a portion of the light-transmitting structure 500 may be located between the light emitting unit 400 and the light shielding layer 600.

[0055] For further information, please refer to Figure 4In some display panels, in order to prevent water and oxygen from invading the driving backplane 100', a barrier layer 300' covering the driving backplane 100' and the light-emitting unit 400' is provided after bonding the light-emitting unit 400'. Among them, since there is a certain height difference between the side of the light-emitting unit 400' away from the driving backplane 100' and the driving backplane 100', the barrier layer 300' is easily broken at the side wall of the light-emitting unit 400', which affects the water and oxygen protection effect.

[0056] In view of this, please refer to Figure 5 In this embodiment, the risk of the barrier layer 300 breaking can be reduced by setting the light-transmitting structure 500 to be sloped.

[0057] Specifically, in some possible implementations, the display panel provided in this embodiment also includes a barrier layer 300, and the barrier layer 300 is located on a side of the light-transmitting structure 500 away from the driving backplane 100, a side of the light-emitting unit 400 away from the driving backplane 100, and a position where the driving backplane 100 is not covered by the light-transmitting structure 500 and the light-emitting unit 400.

[0058] That is, in this embodiment, after the light emitting unit 400 is bonded and the light-transmitting structure 500 is provided, the barrier layer 300 covering the driving backplane 100 , the light-transmitting structure 500 and the light emitting unit 400 may be provided.

[0059] The light-transmitting structure 500 forms a slope extending from the driving backplane 100 to the side of the light-emitting unit 400 away from the driving backplane 100. The barrier layer 300 extends along the slope from the driving backplane 100 to the side of the light-emitting unit 400 away from the driving backplane 100. The light-shielding layer 600 is located on the side of the barrier layer 300 away from the driving backplane 100.

[0060] Optionally, in this embodiment, the sloped surface of the light-transmitting structure 500 may include a plane, a curved surface or a stepped surface, which is not specifically limited in this embodiment.

[0061] In this way, by setting the light-transmitting structure 500 as a slope, the barrier layer 300 can extend along the slope from the driving backplane 100 to the side of the light-emitting unit 400 away from the driving backplane 100. In this way, the height mutation between the driving backplane 100 and the top of the light-emitting unit 400 is alleviated, thereby reducing the risk of breaking the barrier layer 300.

[0062] For other possible implementations, see Figure 6The display panel provided in this embodiment may further include an anisotropic conductive film 200. The anisotropic conductive film 200 is located on one side of the driving backplane 100 and is used to realize electrical connection between the light emitting unit 400 and the electrodes on the driving backplane 100.

[0063] The display panel provided in this embodiment further includes a barrier layer 300, and the barrier layer 300 is located on a side of the anisotropic conductive film 200, the light-transmitting structure 500, and the light-emitting unit 400 away from the driving backplane 100. That is, in this embodiment, after the light-emitting unit 400 is bonded and the light-transmitting structure 500 is arranged, the barrier layer 300 covering the anisotropic conductive film 200, the light-transmitting structure 500, and the light-emitting unit 400 can be arranged.

[0064] The light-transmitting structure 500 forms a slope extending from the anisotropic conductive film 200 to the side of the light-emitting unit 400 away from the driving backplane 100. The barrier layer 300 extends along the slope from the side of the anisotropic conductive film 200 away from the driving backplane 100 to the side of the light-emitting unit 400 away from the driving backplane 100. The light-shielding layer 600 is located on the side of the barrier layer 300 away from the driving backplane 100.

[0065] Optionally, in this embodiment, the sloped surface of the light-transmitting structure 500 may include a plane, a curved surface or a stepped surface, which is not specifically limited in this embodiment.

[0066] In this way, by setting the light-transmitting structure 500 as a slope, the barrier layer 300 can extend along the slope from the anisotropic conductive adhesive film 200 to the side of the light-emitting unit 400 away from the driving backplane 100. In this way, the height mutation between the anisotropic conductive adhesive film 200 and the top of the light-emitting unit 400 is alleviated, thereby reducing the risk of breaking the barrier layer 300.

[0067] Please refer to Figure 7 , Figure 7 The display surface perspective view of the display panel provided in this embodiment, in some possible implementations, the orthographic projection of the light-emitting unit 400 on the driving backplane 100 is located within the orthographic projection of the light-transmitting structure 500 on the driving backplane 100 .

[0068] That is, in this embodiment, in the direction parallel to the display surface, the light-transmitting structure 500 wraps around the unit. On the one hand, the light emitted by the light-emitting unit 400 can be emitted through the surrounding side walls, thereby improving the light extraction efficiency; on the other hand, the risk of the barrier layer 300 being broken on the surrounding side walls of the light-emitting unit 400 can be reduced, thereby improving the water and oxygen barrier effectiveness.

[0069] Optionally, see Figure 8 In some possible implementations, the light-transmitting structure 500 also covers the side of the light-emitting portion away from the driving backplane 100. That is, in this embodiment, after the light-emitting unit 400 is bonded, a light-transmitting structure 500 that integrally covers the light-emitting portion of the light-emitting unit 400 can be provided to reduce the difficulty of providing the light-transmitting structure 500. Optionally, in this embodiment, the light-transmitting structure 500 can be provided by dispensing glue.

[0070] Optionally, see Fig. 9 In some possible implementations, in the thickness direction of the display panel, the cross-sectional shape of the light-transmitting structure 500 is an arc-shaped structure covering the light-emitting unit 400 .

[0071] In this way, the light-transmitting structure 500 can form a convex lens covering the light-emitting portion of the light-emitting unit 400 , thereby converging the light emitted by the light-emitting unit 400 and improving the light-emitting effect of the display panel.

[0072] Optionally, please refer again to Fig. 9 In some possible implementations, the display panel further includes a planarization layer 700 located on a side of the light shielding layer 600 and the light-transmitting structure 500 away from the driving backplane 100, and the refractive index of the planarization layer 700 is smaller than the refractive index of the light-transmitting structure 500. In this way, the planarization layer 700 and the light-transmitting structure 500 can form a convex lens together.

[0073] Optionally, in this embodiment, when the display panel further includes the barrier layer 300, the refractive index of the barrier layer 300 may be between the planarization layer 700 and the light-transmitting structure 500. In this way, the planarization layer 700, the barrier layer 300 and the light-transmitting structure 500 may form a convex lens together.

[0074] Optionally, in some possible implementations, the refractive index of the light-transmitting structure 500 is greater than or equal to 1.7.

[0075] Optionally, please refer again to Fig. 9In some possible implementations, the distance H1 from the end of the light-transmitting structure 500 away from the driving backplane 100 to the anisotropic conductive adhesive film 200 may be 5 microns to 10 microns. For example, the distance H1 from the point of the light-transmitting structure 500 farthest from the driving backplane 100 to the anisotropic conductive adhesive film 200 may be 5 microns to 10 microns.

[0076] This embodiment further provides a display panel, which may include a driving backplane 100 , at least one light-emitting unit 400 , a slope structure and a barrier layer 300 .

[0077] The light emitting unit 400 is located at one side of the driving backplane 100 and is electrically connected to the driving backplane 100 .

[0078] The slope structure is located at one side of the driving backplane 100 and surrounds at least a portion of the light-emitting portion. The slope structure extends from the driving backplane 100 to a side of the light-emitting unit 400 away from the driving backplane 100 .

[0079] The barrier layer 300 is located on a side of the slope structure away from the driving backplane 100, a side of the light emitting unit 400 away from the driving backplane 100, and a position of the driving backplane 100 not covered by the slope structure and the light emitting unit 400. The barrier layer 300 extends along the slope from a side of the driving backplane 100 away from the driving backplane 100 to a side of the light emitting unit 400 away from the driving backplane 100.

[0080] and Figure 5 , Figure 6 , Figure 8 or Fig. 9 The difference from the illustrated solution is that the slope structure can also be made of a light-proof material.

[0081] Based on the above configuration, by setting the slope structure, the barrier layer 300 for blocking water vapor can extend along the slope structure from the driving backplane 100 to the side of the light-emitting unit 400 away from the driving backplane 100, thereby alleviating the height mutation between the driving backplane 100 and the top of the light-emitting unit 400, thereby reducing the risk of the barrier layer 300 breaking.

[0082] For other possible implementations, see Figure 6 The display panel provided in this embodiment may further include an anisotropic conductive adhesive film 200 .

[0083] The anisotropic conductive film 200 is located on one side of the driving backplane 100. The anisotropic conductive film 200 is used to realize the electrical connection between the light emitting unit 400 and the electrodes on the driving backplane 100.

[0084] The light emitting unit 400 is embedded in the anisotropic conductive film 200 and is electrically connected to the driving backplane 100 through the anisotropic conductive film 200 . The light emitting unit 400 includes a light emitting portion protruding from the anisotropic conductive film 200 .

[0085] The slope structure is located on a side of the ACD film 200 away from the driving backplane 100 and surrounds at least a portion of the light-emitting portion. The slope structure extends from the ACD film 200 to a side of the light-emitting unit 400 away from the driving backplane 100 .

[0086] The barrier layer 300 is located on the side of the anisotropic conductive film 200, the slope structure and the light emitting unit 400 away from the driving backplane 100. The barrier layer 300 extends along the slope from the side of the anisotropic conductive film 200 away from the driving backplane 100 to the side of the light emitting unit 400 away from the driving backplane 100.

[0087] This embodiment further provides an electronic device, which may include the display panel provided in this embodiment. The electronic device may include a display, a spliced ​​display screen, a mobile phone, a tablet computer, a laptop computer, a television, and other devices with display functions.

[0088] In summary, the display panel and electronic device provided by the present application provide a light-transmitting structure surrounding at least part of the light-emitting unit, so that the side wall of the light-emitting unit and the light-shielding layer have a certain distance. In this way, the light-shielding layer can be prevented from directly blocking the side wall of the light-emitting unit, so that the light emitted from the side of the light-emitting unit can also be emitted through the light-transmitting structure, thereby improving the light extraction rate of the display panel.

[0089] In addition, by setting the light-transmitting structure as a slope, the barrier layer used to block water vapor can extend along the slope from the driving backplane to the side of the light-emitting unit away from the driving backplane, thereby alleviating the height mutation between the driving backplane and the top of the light-emitting unit, thereby reducing the risk of the barrier layer breaking.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
