[0046] Please see Figure 1 and Figure 2 , Figure 1 This is a partial structural diagram of an electronic device in one embodiment; Figure 2 This is a partial structural diagram of an electronic device in one embodiment.

[0047] like Figure 1 and Figure 2As shown, an embodiment of the first aspect of this application provides an electronic device 100. The electronic device 100 includes a frame assembly 110, a cover plate 120, a display panel 130, and a light-shielding assembly 140. The frame assembly 110 includes a wall panel 111 and a cavity 112 enclosed by the wall panel 111 and opening in a first direction X. The cover plate 120 covers the opening and includes a planar portion 121 and a curved portion 122 connected to each other. The curved portion 122 is connected to the wall panel 111. The display panel 130 is disposed in the cavity 112, with the light-emitting surface and the planar portion 121 facing each other. The light-shielding assembly 140 includes a first light-shielding portion. The frame assembly 110 includes a first light-shielding part 141 and a second light-shielding part 142. The first light-shielding part 141 is disposed on the inner surface of the curved surface 122, and the second light-shielding part 142 is disposed on the outer surface of the curved surface 122. The first light-shielding part 141 is used to absorb at least part of the light, and the second light-shielding part 142 is used to block at least part of the light from escaping from the cover plate 120. The frame assembly 110 also includes an adhesive layer 113, which is disposed between the wall panel 111 and the cover plate 120. The curved surface 122 is bonded to the wall panel 111 through the adhesive layer 113. One end of the second light-shielding part 142 is connected to the adhesive layer 113, and the other end of the second light-shielding part 142 extends out of the frame assembly 110.

[0048] In the electronic device 100 provided in this application embodiment, the electronic device 100 includes a frame assembly 110, a cover plate 120, a display panel 130, and a light-shielding assembly 140. The frame assembly 110 includes a wall panel 111, a cavity 112 enclosed by the wall panel 111, and an adhesive layer 113 disposed on the wall panel 111. The cover plate 120 covers the opening and includes a planar portion 121 and a curved portion 122 connected to each other. The curved portion 122 is connected to the wall panel 111 through the adhesive layer 113. The display panel 130 is disposed in the cavity 112, and the light-emitting surface of the display panel 130 faces the planar portion 121 so that the display content of the display panel 130 can be seen in the planar portion 121. The light-shielding assembly... 140 includes a first light-shielding part 141 and a second light-shielding part 142. The first light-shielding part 141 is disposed on the inner surface of the curved part 122 to absorb the light from the display panel 130 and reduce the risk of light leakage from the cover plate 120 in the curved part 122. The second light-shielding part 142 is disposed on the outer surface of the curved part 122. One end of the second light-shielding part 142 is connected to the adhesive layer 113, and the other end extends out of the frame assembly 110. This increases the light-shielding area of ​​the second light-shielding part 142 and reduces the probability of light leakage at the gap between the cover plate 120 and the wall panel 111 due to installation errors of the cover plate 120 and the frame assembly 110. This allows the second light-shielding part 142 to reliably improve the problem of light leakage at the edge of the electronic device 100.

[0049] Light leakage occurs at the edge of the electronic device 100, specifically in the gap between the cover plate 120 and the frame assembly 110.

[0050] Optionally, the frame assembly 110 may include a split-formed middle frame and a back panel. The middle frame is usually made of metal (such as aluminum alloy, titanium alloy, etc.) or plastic and serves as the supporting "skeleton" for internal components (such as camera components, audio components, etc.). The back panel and cover plate 120 are respectively connected to the middle frame on both sides in its first direction X. The back panel and cover plate 120 are connected to the middle frame by means of buckles, adhesives or screws.

[0051] For example, the display panel 130 is disposed between the middle frame and the cover plate 120.

[0052] Optionally, the cover plate 120 is a curved cover plate 120. The curved cover plate 120 helps to hide part of the bezel to achieve a higher screen ratio, and the edge curvature of the curved cover plate 120 fits the palm better, making the sliding operation smoother.

[0053] For example, the cover plate 120 can be a 2.5D cover plate or a 3D cover plate, etc.

[0054] Optionally, the cover plate 120 includes a flat portion 121 and a curved portion 122. The flat portion 121 is arranged facing the light-emitting surface of the display panel 130, and the flat portion 121 is the display area. The curved portion 122 is arc-shaped and is disposed at the edge of the flat portion 121 and bent toward the display panel 130. The curved portion 122 is connected to the wall panel 111 of the frame assembly 110.

[0055] Optionally, the curved surface 122 is disposed on both sides of the flat surface 121; or the curved surface 122 is disposed around the periphery of the flat surface 121.

[0056] Optional materials for the cover plate 120 include tempered glass, ceramic crystal glass, polycarbonate, acrylic, flexible plastic, frosted glass, etc.

[0057] Optionally, the display panel 130 is a curved display panel 130, which includes a non-curved area and a curved area located on at least one side of the non-curved area. The non-curved area of ​​the curved display panel 130 corresponds to the flat portion 121 of the cover plate 120, and the curved area of ​​the curved display panel 130 corresponds to the curved portion 122 of the cover plate 120.

[0058] The portion of the curved display panel 130 located in the curved area can be arc-shaped. The flat portion 121 of the cover plate 120 corresponding to the non-curved area of ​​the curved display panel 130 means that when the cover plate 120 covers the curved display panel 130, the flat portion 121 is opposite to the non-curved area, and the shape and size of the flat portion 121 and the non-curved area are basically the same. The curved portion 122 of the cover plate 120 corresponding to the curved area of ​​the curved display panel 130 means that when the cover plate 120 covers the curved display panel 130, the curved portion 122 is opposite to the curved area, and the shape and size of the curved portion 122 and the curved area are basically the same.

[0059] The light-shielding component 140 includes a first light-shielding part 141, which is disposed on the inner surface of the curved surface 122. The first light-shielding part 141 is used to absorb the light reflected from the display panel 130 by the curved surface 122 to reduce the risk of light leakage from the curved surface 122.

[0060] Optionally, the first light-shielding part 141 can be ink disposed on the curved surface 122, which can be used to absorb light and improve the light leakage problem at the edge of the cover plate 120; or the surface of the curved surface 122 can be roughened to form a diffuse reflection layer 1423, which is the first light-shielding part 141.

[0061] Optionally, the diffuse reflective layer 1423 can be dyed or printed with pad ink to deepen its color and enhance its light-blocking effect.

[0062] In related technologies, some of the light emitted by the display panel 130 undergoes total internal reflection on the outer surface of the curved surface 122. At least some of the total internally reflected light cannot be absorbed by the first light-shielding part 141, and some light is emitted from the curved surface 122 and leaks out from the gap between the cover plate 120 and the wall panel 111, resulting in light leakage at the edge of the electronic device 100.

[0063] Therefore, in this embodiment of the application, a second light-shielding part 142 is provided to block light from entering the gap between the cover plate 120 and the wall plate 111 inside the chamber 112.

[0064] Optionally, the second light-shielding part 142 is disposed on the outer surface of the curved part 122.

[0065] For example, the second light-shielding part 142 is an ink layer, an AR coating, a diffuse reflection layer 1423, etc.

[0066] Optionally, the second light-shielding part 142 can be provided on the curved surface 122 by means of bonding, pad printing, spraying, coating, etc. The specific material and size of the second light-shielding part 142 can be designed by the user.

[0067] Optionally, the wall panel 111 includes a base plate 1111 and a side plate 1112 connected to each other. An adhesive layer 113 is disposed on the side plate 1112. A curved surface 122 is connected to the side plate 1112. The adhesive layer 113 and the side plate 1112 are flush with the side away from the base plate 1111, increasing the area of ​​the adhesive layer 113 and enhancing the connection strength between the cover plate 120 and the frame assembly 110. The second light-shielding portion 142 is connected to the adhesive layer 113 and extends out of the frame assembly 110. In addition, the second light-shielding part 142 is used to improve the problem of light leakage between the cover plate 120 and the side plate 1112, reduce the amount of the second light-shielding part 142, and help save the material cost of the light-shielding assembly 140; or the adhesive layer 113 is spaced apart from the side edge of the side plate 1112 away from the bottom plate 1111, then part of the second light-shielding part 142 extends into the frame assembly 110 and connects with the adhesive layer 113, and the other part extends out of the frame assembly 110.

[0068] Optionally, the second light-shielding part 142 extending out of the frame assembly 110 means that the side plate 1112 is located between the edge of the second light-shielding part 142 away from the bottom plate 1111 and the bottom plate 1111.

[0069] Optionally, the side panel 1112 is made of an opaque material. Therefore, even if some light enters the gap between the side panel 1112 and the cover 120 through the cover 120, the user will not observe the problem of light leakage through the gap due to the blocking of the side panel 1112 and the second light-shielding part 142, and there is no problem of light leakage at the edge of the device.

[0070] Optionally, the adhesive layer 113 is an opaque material, which can absorb some light.

[0071] In some embodiments, such as Figure 1 and Figure 2 As shown, the curved surface 122 includes a first end face 1221, a second end face 1222 and a side face 1223 that are connected to each other. The first end face 1221 and the second end face 1222 are respectively disposed on both sides of the curved surface 122 in its thickness direction. The side face 1223 is connected to the adhesive layer 113, and the second light-shielding part 142 covers the entire side face 1223.

[0072] In these embodiments, the curved surface 122 includes a first end face 1221, a second end face 1222, and a side face 1223 that are connected to each other. The side face 1223 is connected to the adhesive layer 113. By covering the entire side face 1223 with the second light-shielding part 142, the shading area of ​​the second light-shielding part 142 is increased so that the second light-shielding part 142 can fully block light leakage from the curved surface 122, thereby better improving the problem of light leakage from the gap between the cover plate 120 and the frame assembly 110.

[0073] Optionally, the first end face 1221 faces the display panel 130, and the first light-shielding part 141 is disposed on the first end face 1221. The first end face 1221 and the second end face 1222 are curved surfaces. The side face 1223 is connected between the first end face 1221 and the second end face 1222. The side face 1223 is flat and is connected to the wall panel 111 through an adhesive layer 113 to reduce the difficulty of fitting the cover plate 120 and the frame assembly 110. The specific dimensions of the side face 1223 can be designed by the user.

[0074] Optional, please refer to Figure 3 , Figure 3 This is a schematic diagram of a partial structure of an electronic device in one embodiment. For example... Figure 3 As shown, some of the light emitted from the display panel 130 undergoes total internal reflection at the second end face 1222. The partially reflected light is more likely to escape to the outside from the side 1223, causing light leakage at the edge of the cover plate 120. Therefore, covering the entire side 1223 with the second light-shielding part 142 can effectively improve the edge light leakage problem of the electronic device 100.

[0075] If part of the side surface 1223 is located outside the frame assembly 110, the second light-shielding part 142 covers the entire side surface 1223, or the second light-shielding part 142 covers the entire side surface 1223 and part of the second end face 1222; if all sides 1223 are located inside the frame assembly 110, or if the side surface 1223 is flush with the adhesive layer 113, the second light-shielding part 142 covers the entire side surface 1223 and part of the second end face 1222.

[0076] Optionally, at least a portion of the second light-shielding portion 142 extends to the first end face 1221 and / or the second end face 1222 to reduce the processing difficulty of the second light-shielding portion 142.

[0077] In some embodiments, such as Figure 1 and Figure 2 As shown, the second light-shielding part 142 includes a first end 1421 and a second end 1422 disposed opposite to each other. The first end 1421 is connected to the adhesive layer 113, and the second end 1422 extends out of the frame assembly 110. The minimum distance L between the second end 1422 and the frame assembly 110 in the first direction X satisfies that L≤40μm.

[0078] In these embodiments, the second light-shielding portion 142 includes a first end 1421 connected to the adhesive layer 113 and a second end 1422 extending out of the frame assembly 110. When the minimum distance L between the second end 1422 and the frame assembly 110 in the first direction X satisfies the above conditions, the problem of a large area of ​​the second light-shielding portion 142 being exposed on the outer surface of the cover plate 120, which makes the second light-shielding portion 142 easy to peel off and increases the risk of edge light leakage of the electronic device 100, can be improved.

[0079] For example, the second light-shielding part 142 is ink. Relatively speaking, the adhesion of ink is weak. Therefore, when a large amount of ink is exposed on the outer surface of the cover plate 120, the ink is at high risk of peeling off in the event of scratches, bumps, etc.

[0080] For example, the minimum spacing L between the second end 1422 and the frame assembly 110 in the first direction X can be 10μm, 20μm, 30μm, 40μm, etc. The specific size of the minimum spacing L between the second end 1422 and the frame assembly 110 in the first direction X can be selected within this range.

[0081] In some embodiments, such as Figure 1 and Figure 2 As shown, 20μm≤L≤40μm.

[0082] In these embodiments, when the minimum distance L between the second end 1422 and the frame assembly 110 in the first direction X satisfies the above conditions, it can both improve the problem that the large area of ​​the second light-shielding part 142 is exposed on the outer surface of the cover plate 120, which makes the second light-shielding part 142 easy to peel off and increases the risk of edge light leakage of the electronic device 100, and improve the problem that the second light-shielding part 142 cannot extend out of the frame assembly 110 due to the fit error between the cover plate 120 and the frame, resulting in a decrease in the light-shielding effect of the second light-shielding part 142.

[0083] For example, the minimum spacing L between the second end 1422 and the frame assembly 110 in the first direction X can be 20μm, 30μm, 40μm, etc.

[0084] In some embodiments, such as Figure 1 and Figure 2 As shown, at least a portion of the second light-shielding portion 142 is located between the adhesive layer 113 and the curved portion 122.

[0085] In these embodiments, at least a portion of the second light-shielding portion 142 is located between the adhesive layer 113 and the curved surface 122. The adhesive layer 113 serves to fix the second light-shielding portion 142, reducing the risk of the second light-shielding portion 142 peeling and breaking under external force, so that the second light-shielding portion 142 can provide more reliable light shielding and reduce the risk of edge light leakage of the electronic device 100.

[0086] Specifically, part of the second light-shielding part 142 is located between the adhesive layer 113 and the curved surface 122, and the other part extends out of the frame assembly 110. The adhesive layer 113 can fix the second light-shielding part 142 to the outer surface of the curved surface 122; and it helps to reduce the difficulty of fitting the second light-shielding part 142 and the adhesive layer 113, and reduce the risk of light leakage due to gaps between the second light-shielding part 142 and the adhesive layer 113 in the first direction X.

[0087] For example, the portion of the second light-shielding part 142 located inside the adhesive layer 113 and the portion located outside the adhesive layer 113 have the same size in the first direction X, so that the adhesive layer 113 can reliably fix the second light-shielding part 142.

[0088] In some embodiments, such as Figure 1 and Figure 2 As shown, the orthographic projection of the adhesive layer 113 onto the curved surface 122 is located within the second light-shielding portion 142.

[0089] In these embodiments, the orthographic projection of the adhesive layer 113 onto the curved surface 122 is located within the second light-shielding portion 142. By increasing the overlapping area of ​​the second light-shielding portion 142 and the adhesive layer 113, the adhesive layer 113 can firmly fix the second light-shielding portion 142 to the curved surface 122, reducing the risk of the second light-shielding portion 142 peeling and breaking under external force, thereby making the second light-shielding portion 142 more reliable in blocking light and reducing the risk of edge light leakage of the electronic device 100.

[0090] Optionally, a portion of the second light-shielding portion 142 extends to the first end face 1221 to reduce the difficulty of fitting the second light-shielding portion 142 and the adhesive layer 113 together.

[0091] Please see Figure 4 , Figure 4 This is a partial structural diagram of an electronic device in another embodiment.

[0092] In some embodiments, such as Figure 2 and Figure 4 As shown, the second light-shielding part 142 is connected to the adhesive layer 113 along the first direction X.

[0093] In these embodiments, the second light-shielding part 142 is connected to the adhesive layer 113 along the first direction X. This not only allows the adhesive layer 113 to bond and fix the second light-shielding part 142, but also reduces the amount of the second light-shielding part 142 used, thus saving the material cost of the light-shielding assembly 140.

[0094] Optionally, the adhesive layer 113 is black glue, so that the adhesive layer 113 can fully absorb light and reduce the risk of light leakage at the edge of the electronic device 100.

[0095] Specifically, the second light-shielding part 142 is disposed between the adhesive layer 113 and the flat surface 121. If the adhesive layer 113 and the side plate 1112 are flush with the edge of the side facing away from the bottom plate 1111, the second light-shielding part 142 is entirely located outside the frame assembly 110; if the adhesive layer 113 is located inside the frame assembly 110, part of the second light-shielding part 142 is located inside the frame assembly 110 and connected to the adhesive layer 113.

[0096] Please see Figure 5 , Figure 5This is a partial structural schematic diagram of an electronic device in another embodiment.

[0097] In some embodiments, such as Figure 1 and Figure 5 As shown, the second light-shielding part 142 includes a light-absorbing layer 1424 for absorbing at least a portion of the light, and / or the second light-shielding part 142 includes a reflective layer 1423 for reflecting at least a portion of the light to the first light-shielding part 141.

[0098] In these embodiments, the second light-shielding portion 142 includes a light-absorbing layer 1424, which can absorb light emitted from the curved surface 122 to reduce the risk of light leakage at the edge of the electronic device 100; or the second light-shielding portion 142 includes a reflective layer 1423, which can reflect light incident on the curved surface 122 to the first light-shielding portion 141 and be absorbed by the first light-shielding portion 141 to reduce the risk of light leakage at the edge of the electronic device 100.

[0099] Optionally, in the same cover plate 120, the second light-shielding part 142 can all be light-absorbing layers 1424, or in the same cover plate 120, the second light-shielding part 142 can all be reflective layers 1423, or in the same cover plate 120, the second light-shielding part 142 can simultaneously include light-shielding layers and reflective layers 1423 connected to each other. The specific dimensions of the light-shielding layer and reflective layer 1423 can be designed according to the actual situation.

[0100] Optionally, the light-absorbing layer 1424 includes an ink layer, which can be designed onto the outer surface of the curved surface 122 by means of transfer printing, pad printing, bonding, coating, or deposition.

[0101] Optionally, the reflective layer 1423 can be an AR coating (Anti-Reflective Coating) or a diffuse reflection layer 1423. The AR coating can be obtained by vacuum deposition or ion-assisted deposition technology; the diffuse reflection layer 1423 can be obtained by roughening the outer surface of the curved surface 122.

[0102] Please see Figure 6 , Figure 6 This is a partial structural schematic diagram of an electronic device in another embodiment.

[0103] In some embodiments, such as Figure 6As shown, the second light-blocking part 142 includes a light-absorbing layer 1424, which includes a first sub-light-absorbing layer 1425 and a second sub-light-absorbing layer 1426. The adhesion force F1 between the first sub-light-absorbing layer 1425 and the cover plate 120 and the adhesion force F2 between the second sub-light-absorbing layer 1426 and the cover plate 120 satisfy F1 > F2. The first sub-light-absorbing layer 1425 is connected between the cover plate 120 and the second sub-light-absorbing layer 1426.

[0104] In these embodiments, the light-absorbing layer 1424 includes a first sub-light-absorbing layer 1425 and a second sub-light-absorbing layer 1426 that are interconnected. The adhesion between the first sub-light-absorbing layer 1425 and the cover plate 120 is greater than the adhesion between the second sub-light-absorbing layer 1426 and the cover plate 120. The first sub-light-absorbing layer 1425 is connected between the cover plate 120 and the second sub-light-absorbing layer 1426. The first sub-light-absorbing layer 1425 can fix the second sub-light-absorbing layer 1426. Therefore, the cooperation between the first sub-light-absorbing layer 1425 and the second sub-light-absorbing layer 1426 helps to improve the connection reliability between the light-absorbing layer 1424 and the cover plate 120 and reduce the risk of the light-absorbing layer 1424 peeling off.

[0105] Optionally, the OD (Optical Density) value of the second sub-absorbing layer 1426 is greater than the OD value of the first sub-absorbing layer 1425, so as to enhance the overall light-blocking ability of the light-absorbing layer 1424 through the second sub-absorbing layer 1426.

[0106] Optionally, the adhesion between the first sub-light-absorbing layer 1425, the second sub-light-absorbing layer 1426, and the cover plate 120 can be tested by methods such as tape peeling, friction testing, and solvent wiping.

[0107] For example, a first sub-light-absorbing layer 1425 and a second sub-light-absorbing layer 1426 of the same shape and area are transferred onto the surface of the test cover plate 120. Standard tape (such as 3M tape) is flatly pasted onto the surface of the first sub-light-absorbing layer 1425 and the second sub-light-absorbing layer 1426, and then quickly peeled off at a 45° or 180° angle. The residue of the first sub-light-absorbing layer 1425 and the second sub-light-absorbing layer 1426 on the surface of the test cover plate 120 is checked. The more residue, the greater the adhesion between the first sub-light-absorbing layer 1425 and the cover plate 120. The first sub-light-absorbing layer 1425 and the second sub-light-absorbing layer 1426 of the same shape and area are transferred onto the surface of the test cover plate 120. The surface of the first sub-light-absorbing layer 1425 and the second sub-light-absorbing layer 1426 is rubbed with a fixed pressure and number of times using a friction tester or by hand (such as an eraser or cellophane). The wear is observed. The lighter the wear, the greater the adhesion between the first sub-light-absorbing layer 1425 and the cover plate 120.

[0108] Optionally, the OD values ​​of the first sub-absorbing layer 1425 and the second sub-absorbing layer 1426 can be determined by an optical density meter.

[0109] For example, the first sub-light-absorbing layer 1425 can be one or more of epoxy acrylic ink, UV ink, water-based ink, solvent-based mixed ink, etc.

[0110] For example, the second light-absorbing layer 1426 can be one or more of UV-curable inks, styrene-based gravure inks, soybean inks, etc.

[0111] Please see Figure 7 , Figure 7 This is a schematic diagram of the structure of a light-shielding component of an electronic device in one embodiment.

[0112] In some embodiments, such as Figure 6 and Figure 7 As shown, at least a portion of the first sub-absorbing layer 1425 is located outside the second sub-absorbing layer 1426 in the orthographic projection of the cover plate 120.

[0113] In these embodiments, at least a portion of the first sub-light-absorbing layer 1425 is located outside the second sub-light-absorbing layer 1426 in the orthographic projection of the cover plate 120. The first sub-light-absorbing layer 1425 serves to wrap around the second sub-light-absorbing layer 1426, reducing the risk of the second sub-light-absorbing layer 1426 peeling off under external force and improving the reliability of the second light-shielding part 142.

[0114] Specifically, at least a portion of the first sub-light-absorbing layer 1425 is located outside the second sub-light-absorbing layer 1426, so that the first sub-light-absorbing layer 1425 can serve to fix the second sub-light-absorbing layer 1426.

[0115] In some embodiments, such as Figure 6 and Figure 7 As shown, the first sub-light-absorbing layer 1425 is disposed around the outer periphery of the second sub-light-absorbing layer 1426.

[0116] In these embodiments, the first sub-light-absorbing layer 1425 is disposed around the outer periphery of the second sub-light-absorbing layer 1426. This can increase the contact area between the first sub-light-absorbing layer 1425 and the second sub-light-absorbing layer 1426, so that the first sub-light-absorbing layer 1425 can better fix the second sub-light-absorbing layer 1426. It can also save the volume of the first sub-light-absorbing layer 1425 and reduce the material cost of the light-absorbing layer 1424.

[0117] Optionally, the first sub-light-absorbing layer 1425 is arranged in a ring around the outer periphery of the second sub-light-absorbing layer 1426.

[0118] For example, the width of the first sub-light-absorbing layer 1425 is uniform at all points to balance the connection strength between the light-absorbing layer 1424 and the cover plate 120; or the width of the first sub-light-absorbing layer 1425 at the end away from the base plate 1111 is greater than the width of the first sub-light-absorbing layer 1425 at the end near the base plate 1111, so as to improve the protective effect of the first sub-light-absorbing layer 1425 on the second sub-light-absorbing layer 1426.

[0119] Please see Figure 8 , Figure 8 This is a partial structural diagram of an electronic device in one embodiment.

[0120] In some embodiments, such as Figure 8 As shown, the second sub-light-absorbing layer 1426 is disposed between the first sub-light-absorbing layer 1425 and the cover plate 120 along its thickness direction.

[0121] In these embodiments, the second sub-light-absorbing layer 1426 is disposed between the first sub-light-absorbing layer 1425 and the cover plate 120 along its thickness direction, increasing the contact area between the first sub-light-absorbing layer 1425 and the second sub-light-absorbing layer 1426, so that the first sub-light-absorbing layer 1425 can better fix the second sub-light-absorbing layer 1426 and reduce the risk of the second sub-light-absorbing layer 1426 peeling off.

[0122] Optionally, the second sub-light-absorbing layer 1426 covers the entire first sub-light-absorbing layer 1425 in the orthographic projection of the cover plate 120.

[0123] Optionally, the second sub-light-absorbing layer 1426 is disposed between the first sub-light-absorbing layer 1425 and the cover plate 120 along its thickness direction. The surface area of ​​the first sub-light-absorbing layer 1425 is larger than the surface area of ​​the second sub-light-absorbing layer 1426, and the second sub-light-absorbing layer 1426 is located within the first sub-light-absorbing layer 1425.

[0124] In some embodiments, such as Figure 6 and Figure 8 As shown, the wall panel 111 includes a bottom plate 1111 and a side plate 1112 that are connected to each other. An adhesive layer 113 is disposed on the side plate 1112, and a second sub-light-absorbing layer 1426 is located inside the frame assembly 110.

[0125] In these embodiments, the second sub-light-absorbing layer 1426 is located inside the frame assembly 110. By allowing the first sub-light-absorbing layer 1425 with better adhesion to extend out of the frame assembly 110, the risk of the light-absorbing layer 1424 peeling off under external force is effectively reduced, and the risk of light leakage at the edge of the electronic device 100 is reduced.

[0126] Specifically, if the second sub-light-absorbing layer 1426 and the side plate 1112 are flush with the side away from the bottom plate 1111, then the first sub-light-absorbing layer 1425 is located outside the frame assembly 110; or if the second sub-light-absorbing layer 1426 is located between the bottom plate 1111 and the side plate 1112 on the side away from the bottom plate 1111, then a part of the first sub-light-absorbing layer 1425 is located inside the frame assembly 110, and the other part extends out of the frame assembly 110.

[0127] Please see Figure 9 , Figure 9 This is a partial structural diagram of an electronic device in one embodiment.

[0128] In some embodiments, such as Figure 1 and Figure 9 As shown, the display panel 130 includes an array substrate 131, a light-emitting device layer 132, and an encapsulation layer 133. The light-emitting device layer 132 is located between the array substrate 131 and the encapsulation layer 133, and the encapsulation layer 133 is located between the cover plate 120 and the light-emitting device layer 132. The display panel 130 also includes a functional layer 134, which is disposed between the light-emitting device layer 132 and the encapsulation layer 133. The refractive index of the functional layer 134 is less than that of the encapsulation layer 133.

[0129] In these embodiments, by providing a functional layer 134 with a refractive index lower than that of the encapsulation layer 133 between the light-emitting device layer 132 and the encapsulation layer 133, the light entering the encapsulation layer 133 is deflected in the thickness direction due to refraction by the functional layer 134, reducing the emission angle when it reaches the light-emitting surface of the curved surface 122. This improves the problem that the light emitted from the light-emitting device layer 132 undergoes total internal reflection in the cover plate 120 because the emission angle of the encapsulation layer 133 is greater than or equal to the critical angle of total internal reflection of the curved surface 122, causing the light to propagate laterally along the encapsulation layer 133 and resulting in light leakage at the edge of the electronic device 100.

[0130] In some embodiments, such as Figure 1 and Figure 9 As shown, the encapsulation layer 133 includes a first barrier film layer 1331, a second barrier film layer 1332 and a third barrier film layer 1333 stacked in sequence. The functional layer 134 is connected to the first barrier film layer 1331, and the refractive index of the functional layer 134 is less than the refractive index of the first barrier film layer 1331.

[0131] In these embodiments, the refractive index of the functional layer 134 is less than that of the first barrier film layer 1331, so as to facilitate control of the refractive index of the functional layer 134.

[0132] For example, as shown in the figure, a first inorganic barrier film layer is first formed on the light-emitting device layer 132 using chemical vapor deposition (CVD) technology. Then, a first organic barrier film layer is formed on the first inorganic barrier film layer using inkjet printing technology. Next, a second inorganic barrier film layer is formed on the first organic barrier film layer using chemical vapor deposition technology. A touch layer 1334 is formed on the second inorganic barrier film layer. An optical adhesive layer 1335 is formed on the surface of the touch layer 1334. The refractive index of the first inorganic barrier film layer is 1.77, the refractive index of the first organic barrier film layer is 1.52, the refractive index of the second inorganic barrier film layer is 1.82, the refractive index of the touch layer 1334 is 1.86, the refractive index of the optical adhesive layer 1335 is 1.46, and the cover plate 120 is made of aluminosilicate glass with a refractive index of 1.5. Therefore, the refractive index n of the functional layer 134 satisfies 1 ≤ n < 1.77.

[0133] Optionally, the functional layer 134 is a film with a refractive index close to 1 to reduce total internal reflection of light.

[0134] For example, if the refractive index of the functional layer 134 is 1, then the critical condition for total internal reflection is that the light emission angle is 89.9°. Therefore, there will be no total internal reflection of light on the light emission surface of the curved surface 122 when the light emission angle of the light-emitting device layer 132 is between 0° and 89.9°.

[0135] For example, the functional layer 134 is porous silica or fluororesin, etc.
