[0062] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.
[0063] See also Figures 1 to 3 , Figure 1 is a three-dimensional schematic diagram of an embodiment of the electronic device of the present invention; Figure 2 is an exploded schematic diagram of an embodiment of the electronic device of the present invention; Figure 33D schematic diagram of the diffusion element of the electronic device of the present invention. The electronic device of the present invention comprises a backlight module 10, a panel 20, a diffusion element 30, a peripheral light source 40 and a rear shell 50. The backlight module 10 provides the panel 20 with a display light source, the rear shell 50 and the panel 20 are respectively arranged on opposite sides of the backlight module 10, and the outer edge of the diffusion element 30 has a step difference 35 and is arranged along the peripheral contour of the panel 20 in a bevel overlap manner. In this way, in addition to improving the allowable tolerance when assembling the rear shell 50, the step difference 35 design of the diffusion element 30 can also shield part of the viewing angle to reduce the situation where the peripheral light source 40 is directly seen from the seam.
[0064] See also Figure 2 And cooperate Figure 4 and Figure 5 , Figure 4 For along Figure 1 Schematic diagram of a three-dimensional cross-section drawn by the cutting line 4-4 in the embodiment; Figure 5 for Figure 4 A partial enlarged view of the circled area 5. The backlight module 10 includes a frame 11 and a backlight assembly 12, and the backlight assembly 12 is disposed on the frame 11. The frame 11 is a hollow frame (i.e., a U-shaped frame) and has an outer surface 111, and the outer surface 111 surrounds and constructs a general appearance of the electronic device. The outer surface 111 has a front side end 1111 and a rear side end 1112 opposite to each other, and the panel 20 is attached to the front side end 1111. In some embodiments, the size of the panel 20 is larger than the size of the frame 11, so that after the panel 20 is attached to the front side end 1111 of the frame 11, the panel 20 protrudes from the outer surface 111 of the frame 11.
[0065] The backlight assembly 12 provides a display light source (i.e., a light source required for displaying an image) to the panel 20. In some embodiments, the backlight assembly 12 may include a light emitting element and various optical elements, the optical element may be, for example but not limited to, a light guide plate, an optical film, or a combination thereof, and the optical film may be, for example but not limited to, a polarizer, a brightness enhancement film, a diffuser, or a reflector, or a combination thereof, and the light emitted by the light emitting element passes through the optical element to provide the panel 20 with a sufficiently bright and uniform display light source.
[0066] See also Figure 2 and Figure 3 Each diffusion element 30 has a first end surface 31 and a second end surface 32, and two adjacent diffusion elements 30 are spliced with the first end surface 31 abutting against the second end surface 32. In addition, each diffusion element 30 has a first surface 33 and a second surface 34 that are parallel and opposite to each other, and the first surface 33 and the second surface 34 have different areas, so that there is a step 35 between the first surface 33 and the second surface 34.
[0067] See also Figure 1 , Figure 2and Figure 3 In some embodiments, the panel 20 is a long rectangular panel 20 with an arc. In these embodiments, four diffusion elements 30 are spliced around the periphery of the panel 20. The shapes of the four diffusion elements 30 are two long strip diffusion elements 30 and two U-shaped diffusion elements 30 (such as Figure 3 As shown in FIG. 2 , two long strip-shaped diffusion elements 30 are located at the long sides of the panel 20, and two U-shaped diffusion elements 30 are located at the short sides of the panel 20 and are spliced with each of the long strip-shaped diffusion elements 30. It is worth noting that the overall appearance of each diffusion element 30 is determined according to the number of splicing elements and the overall appearance of the electronic device, and is not limited to the aforementioned embodiment.
[0068] See also Figures 3 to 5 In some embodiments, the first end surface 31 and the second end surface 32 of each diffusion element 30 are inclined surfaces relative to the first surface 33 and the second surface 34, that is, the angles between the first end surface 31 and the second end surface 32 and the first surface 33 and the second surface 34 are not equal to 90 degrees.
[0069] See also Figures 3 to 5 And cooperate Figures 6 to 9 , Figure 6 A three-dimensional cross-sectional view of an embodiment of the electronic device of the present invention Figure 2 ; Figure 7 for Figure 6 A partial enlarged view of the selected area 7 in the middle circle; Figure 8 for Figure 7 Floor plan of Fig. 9 for Figure 8 A partial enlarged view of the circled area 9. In these embodiments, the first end surface 31 and the second end surface 32 extend between the first surface 33 and the second surface 34 respectively, and the first end surface 31 and the second end surface 32 of two adjacent diffusion elements 30 can be butted against each other. Here, since the diffusion elements 30 are butted against each other by the first end surface 31 and the second end surface 32 of the inclined surface, even if the first end surface 31 and the second end surface 32 of two adjacent diffusion elements 30 have a dimensional tolerance and cannot be completely fitted, the inclined surface of the first end surface 31 and the second end surface 32 is located at the joint of the two adjacent diffusion elements 30. When the user views the panel 20, the user's line of sight usually views the panel 20 from a direction perpendicular to the panel 20. In this state, the user's line of sight is also perpendicular to the first surface 33 of the diffusion element 30. In this viewing angle direction, even if there is actually a joint between the first end surface 31 and the second end surface 32, since the user's line of sight is not parallel to the extension direction of the first end surface 31 and the second end surface 32, when the user's line of sight looks into the joint, only the inclined surface 31 or the second end surface 32 (such as Figure 8The viewing angle direction shown has an angle with the extension direction of the first end surface 31 and the second end surface 32, that is, the viewing angle direction is not parallel to the extension direction of the first end surface 31 and the second end surface 32), so that the light-emitting element 42 of the internal peripheral light source 40 will not be directly seen, thereby allowing a slight dimensional tolerance between the diffusion elements 30 and still achieving a seamless visual effect, reducing the difficulty of manufacturing and assembly.
[0070] See also Figures 3 to 5 In some embodiments, the angles between the first end surface 31 and the second end surface 32 and the first surface 33 and the second surface 34 are 45 degrees. In these embodiments, the first end surface 31 and the second end surface 32 of the diffusion element 30 can be easily processed and manufactured, and can reduce the restrictions during assembly and improve the convenience of assembly.
[0071] See also Figures 3 to 5 And cooperate Figures 10 to 12 , Fig.10 for Figure 4 Schematic diagram of the plane; Fig.11 for Fig.10 A partial enlarged view of the circled area 11; Fig.12 for Fig.11 A partial enlarged view of the circled area 12. In some embodiments, the step 35 between the first surface 33 and the second surface 34 includes a first plane 351 and a second plane 352 connected to each other. In these embodiments, the first plane 351 is parallel to the first surface 33 and the second surface 34 and is located between the first surface 33 and the second surface 34, and the second plane 352 is perpendicular to the first plane 351 and is connected between the second surface 34 and the first plane 351.
[0072] See also Figure 2 In some embodiments, each diffusion element 30 is directly spliced and combined with a surface of the panel 20 close to the backlight assembly 12. In these embodiments, each diffusion element 30 and each diffusion element 30 and the panel 20 can be combined by gluing, but not limited to.
[0073] See also Figure 4 and Figure 5 , each diffusion element 30 is disposed on one side of the panel 20 along the contour of the panel 20. In some embodiments where the panel 20 protrudes from the outer peripheral surface 111 of the frame 11, each diffusion element 30 is disposed at a position where the panel 20 protrudes from the frame 11. In this way, the backlight assembly 12 of the backlight module 10 provides the main display light source for the panel 20, while the light of the peripheral light source 40 can be uniformly emitted through the diffusion elements 30 around the panel 20, for example, forming an annular aperture surrounding the periphery of the panel 20, especially at the rear periphery of the display surface of the panel 20.
[0074] See also Figure 4 , Figure 5, the peripheral light source 40 is disposed on the outer surface 111 of the frame 11. In some embodiments, the peripheral light source 40 includes a substrate 41 and a plurality of light-emitting elements 42. One side of the substrate 41 is abutted against the outer surface 111 of the frame 11, and each light-emitting element 42 is disposed on the other side of the substrate 41. In some embodiments, the substrate 41 may be, but is not limited to, a flexible printed circuit (Flexible Printed Circuit, referred to as FPC) or a printed circuit board (Printed Circuit Board, referred to as PCB). The light-emitting element 42 may be, but is not limited to, a light-emitting diode (Light Emitting Diode, referred to as LED). In some embodiments, the peripheral light source 40 is completely disposed along the outer surface 111 of the frame 11, so that the entire outer surface 111 of the frame 11 can produce a light-emitting effect.
[0075] See also Figures 10 to 12 In some embodiments, the peripheral light source 40 is disposed on the peripheral surface 111 with a substrate 41 and adjacent to the rear side end 1112, while each diffusion element 30 is adjacent to the front side end 1111 against the panel 20. In some embodiments, in a direction perpendicular to the peripheral surface 111, there is a distance D between the diffusion element 30 and the peripheral surface 111. In this way, in these embodiments, the diffusion element 30 is located on one side of the peripheral light source 40 and is not coplanar. The light emitted by the light-emitting element 42 on the peripheral light source 40 can be converted into a softer and more uniform surface light source after passing through the diffusion element 30. The light-emitting element 42 can be, but is not limited to, a side-emitting light-emitting diode, that is, the light-emitting surface of the light-emitting element 42 faces the second surface 34 of the diffusion element 30.
[0076] See also Fig.12 In some embodiments, each diffusion element 30 further includes a relative outer surface 36 and an inner surface 37, the outer surface 36 is connected between the first surface 33 and the first plane 351, the inner surface 37 is connected between the first surface 33 and the second surface 34, the inner surface 37 is closer to the outer surface 111 than the outer surface 36, and there is the aforementioned distance D between the inner surface 37 and the outer surface 111.
[0077] See also Figure 1 , Figure 2 And cooperate Figures 6 to 8 The rear shell 50 covers the other side of the backlight module 10 to construct a complete electronic device. In some embodiments, the rear shell 50 can be coupled to the backlight module 10 through, but not limited to, a locking member.
[0078] See also Figure 1 , Figure 2 and Figure 4 , Figure 5In some embodiments, the rear shell 50 is a concave shell structure and has an opening 51, and the opening 51 has an edge 511. When the rear shell 50 is assembled to the backlight module 10, the position of the edge 511 of the opening 51 of the rear shell 50 corresponds to the position of the step 35 of each diffusion element 30, so that the combination position of the rear shell 50 and each diffusion element 30 is located at the step 35, and the second plane 352 of the step 35 can provide the purpose of viewing angle shielding.
[0079] In some embodiments, the edge 511 of the opening 51 of the rear shell 50 is adjacent to the step 35 of each diffusion element 30. In these embodiments, when the rear shell 50 is adjacent to the step 35 of each diffusion element 30, the rear shell 50 overlaps the first plane 351 in a direction perpendicular to the first plane 351, and overlaps the second plane 352 in a direction perpendicular to the second plane 352. In other words, the edge 511 of the rear shell 50 can be adjacent to each diffusion element 30 in a state of extending into the step 35, thereby allowing the rear shell 50 to partially overlap each diffusion element 30, further improving the viewing angle shielding effect provided by each diffusion element 30.
[0080] In these embodiments, when the rear shell 50 is adjacent to the step 35 of each diffusion element 30, each diffusion element 30 is partially located inside the rear shell 50 and partially located outside the rear shell 50. Specifically, the edge 511 of the rear shell 50 faces the first plane 351 of the step 35, and the second surface 34 of each diffusion element 30 is completely located inside the rear shell 50, and the first surface 33 of each diffusion element 30 is completely located outside the rear shell 50.
[0081] See also Fig.10 and Fig.12 When there is a gap between the rear housing 50 and each diffusion element 30 due to assembly or processing errors, even if the user's line of sight looks into the gap between the rear housing 50 and each diffusion element 30, the user's line of sight will be blocked by the second plane 352 of the step 35 of each diffusion element 30 and the user will not directly see the light-emitting element 42 of the peripheral light source 40, ensuring that the light viewed by the user is uniform light converted by each diffusion element 30, ensuring that the peripheral light source 40 produces a soft and uniform lighting effect, and can provide different lighting ranges and effects with the backlight assembly 12.
[0082] See also Fig.11 In some embodiments, to ensure that the second plane 352 of the step 35 of each diffusion element 30 can play its sight shielding effect, the ratio of the extension length of the first plane 351 to the extension length of the second plane 352 is preferably 2.5-1. Fig.10 , 11In the illustrated embodiment, the ratio of the extension length of the first plane 351 to the extension length of the second plane 352 is 2. Under this ratio, the second plane 352 can effectively block the line of sight, preventing the user from directly seeing the light-emitting elements 42 of the peripheral light source 40 through the gap between the rear shell 50 and each diffusion element 30.
[0083] See also Fig.12 In these embodiments, the first plane 351 of the step 35 of each diffusion element 30 has a first free end 3511 and a first connecting end 3512 opposite to each other. The end of the first plane 351 away from the second plane 352 is the first free end 3511, and the end of the first plane 351 connected to the second plane 352 is the first connecting end 3512. In addition, the second plane 352 of the step 35 has a second free end 3521 and a second connecting end 3522 opposite to each other. The end of the second plane 352 away from the first plane 351 is the second free end 3521, and the end of the second plane 352 connected to the first plane 351 is the second connecting end 3522. The extension length of the first plane 351 is the length from the first free end 3511 to the first connecting end 3512, and the extension length of the second plane 352 is the length from the second free end 3521 to the second connecting end 3522.
[0084] See also Fig.12 In some embodiments, the angle θ between the line connecting the first free end 3511 of the first plane 351 and the second free end 3521 of the second plane 352 of each diffusion element 30 and the first plane 351 is between 20 and 45 degrees. Fig.12 In the illustrated embodiment, an angle θ between a line connecting the first free end 3511 of the first plane 351 and the second free end 3521 of the second plane 352 and the first plane 351 is between 25 and 27 degrees. Under this ratio, the second plane 352 can effectively block the line of sight, thereby preventing the user from directly seeing the light-emitting elements 42 of the peripheral light sources 40 through the gap between the rear shell 50 and each diffusion element 30.
[0085] See also Fig.11In some embodiments, in the direction perpendicular to the first surface 33 and the second surface 34, there is a first height H1 between the first surface 33 and the first plane 351, a second height H2 between the second plane 352, and a third height H3 between the center position of the light emitting element 42 of the peripheral light source 40 and the second surface 34, and the ratio of the third height H3 to the second height H2 is 3.65. It is worth noting that in the direction perpendicular to the first surface 33 and the second surface 34, the greater the distance between the light emitting element 42 of the peripheral light source 40 and each diffusion element 30, the less likely it is to be seen by the user, that is, the higher the third height H3 is, the better the shielding effect can be exerted. Therefore, the ratio of the third height H3 to the second height H2 can exert the shielding effect when it is between 3.65 and 7.3.
[0086] See also Fig.11 In some embodiments, the ratio of the first height H1 to the second height H2 can be, but is not limited to, 1.5. In other embodiments, the higher the second height H2 of the second plane 352 is, the better the shielding effect can be achieved. Therefore, the ratio of the first height H1 to the second height H2 can have a shielding effect when it is between 0.5 and 1.5.
[0087] See also Fig.11 and Fig.12 In some embodiments, in a direction perpendicular to the second plane 352, the first free end 3511 and the first connecting end 3512 of each diffusion element 30 have a first length L1, and the ratio of the first length L1 to the first height H1 is 4:3. Thus, the step 35 of each diffusion element 30 provides enough space for the rear housing 50 to be assembled and can maintain the sight shielding effect.
[0088] See also Fig.12 In some embodiments, in a direction perpendicular to the second plane 352, the first surface 33 has a second length L2, and the ratio of the second length L2 to the first length L1 is 1.625, but the present invention is not limited thereto. In other embodiments, the smaller the length of the first surface 33, the less likely it is to be seen through the gap between the rear shell 50 and the diffusion element 30. Therefore, when the ratio of the second length L2 to the first length L1 is 1.6 to 3.2, the same effect can be achieved.
[0089] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
