Abstract

This application provides a display panel and an electronic device. The display panel includes: a driving backplate; at least one light-emitting unit located on one side of the driving backplate and electrically connected to the driving backplate; a light-transmitting structure surrounding at least a portion of the light-emitting unit; and a light-shielding layer located on one side of the driving backplate, the light-shielding layer including pixel openings exposing the light-emitting unit and at least a portion of the light-transmitting structure.

Description

Technical Field

[0001] This application relates to the field of display technology, and more specifically, to a display panel and an electronic device. Background Technology

[0002] With the development of display device manufacturing technology, Mini LEDs and Micro-LEDs have become widely used due to their superior advantages in brightness, resolution, contrast ratio, energy consumption, lifespan, response speed, and thermal stability. Mini LED and Micro-LED panel technology involves bonding multiple tiny individual LED light-emitting units to an electrode layer on a driving backplane to form a display panel. To reduce the reflection of external light by the exposed electrode layers between the light-emitting units, some display panels incorporate a light-shielding layer between the units. However, this light-shielding layer covers the sidewalls of the light-emitting units, affecting the light extraction efficiency of the display panel. Summary of the Invention

[0009] In some possible implementations, the display panel further includes a barrier layer located on the side of the light-transmitting structure away from the driving back plate, on the side of the light-emitting unit away from the driving back plate, and at a location where the driving back plate is not covered by the light-transmitting structure and the light-emitting unit;

[0010] Preferably, the light-transmitting structure forms a slope extending from the driving back plate toward the side of the light-emitting unit away from the driving back plate; the barrier layer extends along the slope from the side near the driving back plate to the side of the light-emitting unit away from the driving back plate;

[0011] The light-shielding layer is located on the side of the barrier layer away from the drive backplate;

[0012] Preferably, the display panel further includes an anisotropic conductive film located on one side of the driving backplate; the light-emitting unit is embedded in the anisotropic conductive film and electrically connected to the driving backplate through the anisotropic conductive film, the light-emitting unit includes a light-emitting portion protruding from the anisotropic conductive film; the barrier layer is located on the side of the anisotropic conductive film, the light-transmitting structure and the light-emitting unit away from the driving backplate.

[0013] In some possible implementations, the orthographic projection of the light-emitting unit on the driving backplate lies within the orthographic projection of the light-transmitting structure on the driving backplate.

[0014] In some possible implementations, the light-transmitting structure also covers the side of the light-emitting unit away from the driving backplate.

[0015] In some possible implementations, the cross-sectional shape of the light-transmitting structure in the thickness direction of the display panel is an arc-shaped structure covering the light-emitting unit.

[0016] In some possible implementations, the display panel further includes a planarization layer located on the side of the light-shielding layer and the light-transmitting structure away from the driving backplate, wherein the refractive index of the planarization layer is less than the refractive index of the light-transmitting structure.

[0017] In some possible implementations, the refractive index of the light-transmitting structure is greater than or equal to 1.7.

[0018] This application also provides a display panel, the display panel comprising:

[0019] Drive backplane;

[0020] At least one light-emitting unit electrically connected to the driving backplate;

[0021] A ramp structure located on one side of the drive backplate and surrounding at least a portion of the light-emitting unit, the ramp structure extending from the drive backplate toward the side of the light-emitting unit away from the drive backplate;

[0022] A barrier layer is located on the side of the ramp structure away from the drive back plate, on the side of the light-emitting unit away from the drive back plate, and at a location where the drive back plate is not covered by the ramp structure and the light-emitting unit; the barrier layer extends along the ramp from the side close to the drive back plate to the side of the light-emitting unit away from the drive back plate;

[0025] This application also provides an electronic device, which includes the display panel described above.

[0026] This application provides a display panel and electronic device that, by providing a light-transmitting structure surrounding at least part of the light-emitting units, creates a certain gap between the sidewalls of the light-emitting units and the light-shielding layer. This prevents the light-shielding layer from directly blocking the sidewalls of the light-emitting units, allowing light emitted from the sides of the light-emitting units to also exit through the light-transmitting structure, thereby improving the light extraction efficiency of the display panel.

[0027] 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 side near the drive back plate to the side of the light-emitting unit away from the drive back plate, thus mitigating the height abrupt change between the drive back plate and the top of the light-emitting unit and reducing the risk of barrier layer breakage.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0041] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0042] It should be noted that, where there is no conflict, different features in the embodiments of this application can be combined with each other.

[0043] Please see 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 a driving backplate 100'. To reduce the reflection of external light by the exposed driving backplate 100' between the light-emitting units 400', a light-shielding layer 600' is provided between the light-emitting units 400'. However, the light-shielding layer 600' covers the sidewalls of the light-emitting units 400', causing the light emitted from the sidewalls of the light-emitting units 400' to be absorbed by the light-shielding layer 600' and unable to be emitted, thus reducing the light extraction efficiency of the light-emitting panel.

[0044] In view of this, this embodiment provides a solution to improve the light output of the display panel, and the solution provided in this embodiment will be described in detail below.

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

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

[0047] The light-emitting unit 400 is located on one side of the driving backplate 100 and is electrically connected to the driving backplate 100. For example, the light-emitting unit 400 may be bonded to a bonding electrode on the driving backplate 100.

[0048] The light-transmitting structure 500 is located on one side of the driving backplate 100 and surrounds at least a portion of the light-emitting unit 400. That is, in this embodiment, the light-transmitting structure 500 can cover at least a portion of the side surface of the light-emitting unit 400. Optionally, in this embodiment, the light-transmitting structure 500 can be provided after the light-emitting unit 400 is bonded. 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 backplate 100, and the light-shielding layer 600 includes pixel openings that expose the light-emitting unit 400 and at least a portion of the light-transmitting structure 500. That is, in this embodiment, 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 in a direction parallel to the driving backplate 100.

[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 distance is created between the sidewall of the light-emitting unit 400 and the light-shielding layer 600. This prevents the light-shielding layer 600 from directly blocking the sidewall of the light-emitting unit 400, allowing light emitted from the side of the light-emitting unit 400 to also exit through the light-transmitting structure 500, thereby improving the light extraction efficiency of the display panel.

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

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

[0053] The light-transmitting structure 500 is located on the side of the anisotropic conductive adhesive film 200 away from the driving backplate 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 surface of the light-emitting portion. Optionally, in this embodiment, the light-transmitting structure 500 can be provided after the light-emitting unit 400 is bonded. The material of the light-transmitting structure 500 may include, but is not limited to, light-transmitting photoresist.

[0054] The light-shielding layer 600 is located on the side of the anisotropic conductive film 200 away from the driving backplate 100. The light-shielding layer 600 includes pixel openings that expose the light-emitting portion and at least a portion of the light-transmitting structure 500. That is, in this embodiment, 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 in a direction parallel to the driving backplate 100.

[0055] Further, please refer to Figure 4In some display panels, to prevent water and oxygen from entering the driver backplane 100', a barrier layer 300' is installed after the bonding of the light-emitting unit 400', covering the driver backplane 100' and the light-emitting unit 400'. However, because there is a certain height difference between the side of the light-emitting unit 400' furthest from the driver backplane 100' and the driver backplane 100', the barrier layer 300' is prone to breakage at the sidewall of the light-emitting unit 400', affecting the water and oxygen protection effect.

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

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

[0058] That is, in this embodiment, after bonding the light-emitting unit 400 and setting the light-transmitting structure 500, a barrier layer 300 covering the driving backplate 100, the light-transmitting structure 500 and the light-emitting unit 400 can be set.

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

[0060] Optionally, in this embodiment, the slope surface of the light-transmitting structure 500 forming the ramp may include a plane, an arc surface, or a stepped surface, and no specific limitation is made in this embodiment.

[0061] Thus, by setting the light-transmitting structure 500 as a slope, the barrier layer 300 can extend along the slope from the drive back plate 100 to the side of the light-emitting unit 400 away from the drive back plate 100. This mitigates the abrupt change in height between the drive back plate 100 and the top of the light-emitting unit 400, thereby reducing the risk of the barrier layer 300 breaking.

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

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

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

[0065] Optionally, in this embodiment, the slope surface of the light-transmitting structure 500 forming the ramp may include a plane, an arc surface, or a stepped surface, and no specific limitation is made in this embodiment.

[0066] Thus, by setting the light-transmitting structure 500 as a slope, the barrier layer 300 can extend along the slope from the anisotropic conductive film 200 to the side of the light-emitting unit 400 away from the driving back plate 100. This mitigates the abrupt change in height between the anisotropic conductive film 200 and the top of the light-emitting unit 400, thereby reducing the risk of the barrier layer 300 breaking.

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

[0068] That is, in this embodiment, the light-transmitting structure 500 surrounds the unit in a direction parallel to the display surface. On the one hand, this allows all the light emitted by the light-emitting unit 400 to pass through the surrounding sidewalls, improving light emission efficiency; on the other hand, it reduces the risk of breakage of the barrier layer 300 at the surrounding sidewalls of the light-emitting unit 400, improving the effectiveness of water and oxygen barrier.

[0069] Alternatively, please refer to Figure 8 In some possible implementations, the light-transmitting structure 500 also covers the side of the light-emitting portion away from the driving backplate 100. That is, in this embodiment, after bonding the light-emitting unit 400, a light-transmitting structure 500 that integrally covers the light-emitting portion of the light-emitting unit 400 can be provided, reducing the difficulty of setting the light-transmitting structure 500. Optionally, in this embodiment, the light-transmitting structure 500 can be provided by dispensing adhesive.

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

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

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

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

[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 to again Figure 9In some possible implementations, the distance H1 from the end of the light-transmitting structure 500 furthest from the driving backplate 100 to the anisotropic conductive film 200 can be 5 micrometers to 10 micrometers. For example, the distance H1 from the point of maximum distance of the light-transmitting structure 500 from the driving backplate 100 to the anisotropic conductive film 200 can be 5 micrometers to 10 micrometers.

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

[0077] The light-emitting unit 400 is located on one side of the driving back plate 100 and is electrically connected to the driving back plate 100.

[0078] The ramp structure is located on one side of the drive back plate 100 and surrounds at least part of the light-emitting part, and the ramp structure extends from the drive back plate 100 toward the side of the light-emitting unit 400 away from the drive back plate 100.

[0079] The barrier layer 300 is located on the side of the ramp structure away from the drive back plate 100, on the side of the light-emitting unit 400 away from the drive back plate 100, and at positions on the drive back plate 100 not covered by the ramp structure and the light-emitting unit 400. The barrier layer 300 extends along the ramp from the side of the drive back plate 100 away from the drive back plate 100 to the side of the light-emitting unit 400 away from the drive back plate 100.

[0080] and Figure 5 , Figure 6 , Figure 8 or Figure 9 Unlike the scheme shown, the ramp structure can also be made of an opaque material.

[0081] Based on the above configuration, by setting the slope structure, the barrier layer 300 used to block water vapor can extend along the slope structure from the drive back plate 100 to the side of the light-emitting unit 400 away from the drive back plate 100, thus mitigating the abrupt height change between the drive back plate 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, please refer to Figure 6 The display panel provided in this embodiment may also include anisotropic conductive film 200.

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

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

[0085] The ramp structure is located on the side of the anisotropic conductive film 200 away from the driving backplate 100 and surrounds at least part of the light-emitting part. The ramp structure extends from the anisotropic conductive film 200 toward the side of the light-emitting unit 400 away from the driving backplate 100.

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

[0087] This embodiment also provides an electronic device, which may include the display panel provided in this embodiment. The electronic device may include devices with display functions such as monitors, video wall displays, mobile phones, tablets, laptops, and televisions.

[0088] In summary, the display panel and electronic device provided in this application, by setting a light-transmitting structure around at least part of the light-emitting unit, creates a certain gap between the sidewall of the light-emitting unit and the light-shielding layer. This prevents the light-shielding layer from directly blocking the sidewall of the light-emitting unit, allowing light emitted from the side of the light-emitting unit to also exit through the light-transmitting structure, thereby improving the light extraction efficiency 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 drive back plate to the side of the light-emitting unit away from the drive back plate, which mitigates the height abrupt change between the drive back plate and the top of the light-emitting unit, thereby reducing the risk of barrier layer breakage.

[0090] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0091] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
