Description

Technical Field

[0001] The present application relates to an electronic device, in particular to an electronic device with a light-emitting function. Background Art

[0002] Electronic devices, such as direct-lit backlight modules or display devices, usually have multiple optical films. If the multiple optical films arranged at the edge of the electronic device are offset or rotated during assembly, the bottom plate of the electronic device will be exposed in the gap between the optical films, thereby affecting the overall optical quality of the backlight module or display device. Therefore, the optical films must be limited. The current method of limiting the position of optical films is to fit the optical films together manually by visual inspection. However, this method will have errors, such as the results of different people performing the operation are inconsistent.

[0003] Therefore, an electronic device with a novel structure is needed to improve the above problems. Summary of the invention

[0004] The present application provides an electronic device, comprising a substrate, a first optical film, and a second optical film. The first optical film is disposed on the substrate, wherein the first optical film comprises a snap-fit ​​portion. The second optical film is disposed on the substrate and interferes with the snap-fit ​​portion of the first optical film. The snap-fit ​​portion comprises a first portion, a second portion, and a snap-fit ​​structure, wherein the first portion and the second portion are located on opposite sides of the snap-fit ​​structure, and the first portion and the second portion are respectively located on opposite surfaces of the second optical film.

The second optical film 30 is disposed on the substrate 10, and interferes with the snap-fit ​​portion 21 of the first optical film 20. Here, "mutual interference" may, for example, be "structural interference", wherein structural interference may, for example, represent that there is contact between the two, and they abut against at least a portion of each other's structure, thereby achieving snap-fit ​​and / or limiting, but is not limited thereto.

[0052] In addition, in one embodiment, in the top view direction (i.e., the third direction Z) of the electronic device 1, the second substrate 40 may be disposed on the substrate 10 and partially overlap with the substrate 10, for example, closely attached to the substrate 10, or a spacer (not shown) may be disposed between the second substrate 40 and the substrate 10, but is not limited thereto. In one embodiment, the first optical film 20 and the second optical film 30 may be located between the substrate 10 and the second substrate 40. The second substrate 40 and the first optical film 20 or the second optical film 30 may at least partially overlap in the third direction Z, or may not overlap. In addition, the electronic unit 50 may be disposed on the second substrate 40, so the first optical film 20 and the second optical film 30 may be regarded as being located between the substrate 10 and the electronic unit 50.

[0053] Please refer to the following page Figure 2, further, the engaging portion 21 includes a first portion 211, a second portion 212 and an engaging structure 213. The first portion 211 and the second portion 212 are located on opposite sides of the engaging structure 213, for example, on both sides of the engaging structure 213 along the first direction Y. In one embodiment, the first portion 211 and the second portion 212 can be separated along the first direction Y, that is, the first portion 211 and the second portion 212 have a gap in the first direction Y, and the gap can form the engaging structure 213, and the length of the gap along the first direction Y can be greater than or equal to 0, but is not limited thereto. The first portion 211 and the second portion 212 can be connected to the main body 20a of the first optical film 20. In addition, when the first optical film 20 and the second optical film 30 are engaged and interfere with each other, one of the first portion 211 and the second portion 212 may be located above the relative upper surface 30t of the second optical film 30, and the other may be located below the lower surface 30b. For example, the first portion 211 is adjacent to the upper surface 30t of the second optical film 30 and is located above the upper surface 30t, and the second portion 212 is adjacent to the lower surface 30b of the second optical film 30 and is located below the lower surface 30b. In another embodiment, the first portion 211 may be located below the lower surface 30b of the second optical film 30, and the second portion 212 may be located above the upper surface 30t. In addition, in one embodiment, the second portion 212 is closer to the edge portion 10a of the substrate 10 than the first portion 211, and is not limited thereto. In addition, in one embodiment, the locking structure 213 may be, for example, a groove (i.e., the gap is greater than 0) or a slit (i.e., the gap is equal to 0, in other words, when the first part 211 and the second part 212 are located in the same plane, at least part of the first part 211 can contact the second part 212), but is not limited thereto.

[0054] Please refer again Figure 1A and Figure 2 In one embodiment, the second portion 212 and the second optical film 30 have an overlapping length L3 along the first direction Y. In one embodiment, the overlapping length L3 may be between 5 mm and 15 mm (5 mm≦L3≦15 mm). In one embodiment, the overlapping length L3 may be between 7.5 mm and 12 mm (7.5 mm≦L3≦12 mm). The above values ​​are only examples.

[0055] In one embodiment, the electronic device 1 may be, for example, a backlight module, but is not limited thereto. In one embodiment, the electronic device 1 may be, for example, a direct-type backlight module, but is not limited thereto. In one embodiment, the electronic device 1 may be, for example, a sub-millimeter light-emitting diode (MINI LED) backlight module, but is not limited thereto. In one embodiment, the substrate 10 may be, for example, a backplane of the electronic device 1, but is not limited thereto. In one embodiment, the first optical film 20, the second optical film 30, or the third optical film 60 may be, for example, a reflector, but may also be other types of optical films such as filters, light-enhancing molds, light-guiding films, and are not limited thereto. In addition, in one embodiment, the electronic unit 50 may be, for example, a light-emitting unit, and the light-emitting unit may be, for example, but not limited to, a light-emitting diode. In this case, the second substrate 40 may be a backlight panel, and the electronic device 1 may further include a display panel (not shown), and the second substrate 40 may be disposed between the substrate 10 and the display panel, so that the first optical film 20 and the second optical film 30 may be disposed between the substrate 10 and the plurality of electronic units 50.

[0056] Then match Figure 1B The configuration of the substrate 10, the first optical film 20 and the second optical film 30 is described. Figure 1B The electronic device 1 is shown in a state where the second substrate 40 is removed.

[0057] like Figure 1B As shown, the first optical film 20 and the second optical film 30 may be located adjacent to an edge of the electronic device 1, respectively. The engaging portion 21 of the first optical film 20 may be adjacent to or located at a corner 10c of the substrate 10. The first optical film 20 and the second optical film 30 may be, for example, strip-shaped structures, wherein a main body 30a of the second optical film 30 may extend, for example, in the first direction Y, and a main body 20a of the first optical film 20 may extend, for example, in the second direction X, wherein the first direction Y is substantially perpendicular to the second direction X. The engaging portion 21 may be adjacent to an end of the main body 20a of the first optical film 20. In addition, the first optical film 20 and the second optical film 30 may also have sidewall portions 20s and sidewall portions 30s extending from the main body 20a and the main body 30a along a third direction Z (or extending along a direction slightly offset from the third direction Z, for example, offset 60 degrees from the third direction Z, but not limited thereto), respectively, wherein the third direction Z is substantially perpendicular to the first direction Y and the second direction X, respectively. The side wall portion 20s of the first optical film 20 and the side wall portion 30s of the second optical film 30 can be used to abut against the edge portion 10a of the substrate 10. Figure 2 The side wall portion 20s of the first optical film 20 may be connected to the main body portion 20a of the first optical film 20 and the second portion 212, but is not limited thereto.

[0058] In addition, the substrate 10 may have a protrusion 11 extending along the third direction Z, and the main body 30a of the second optical film 30 may have an opening 31. The size of the opening 31 may be equal to or slightly larger than the size of the protrusion 11 (here, "slightly larger" means that the size of the opening 31 must allow the protrusion 11 to pass through, and the inner wall of the opening 31 must at least partially contact the protrusion 11, so that the protrusion 11 cannot easily fall off from the opening 31), and the position of the opening 31 may correspond to the position of the protrusion 11, so that the protrusion 11 can pass through the opening 31. Through the design of the protrusion 11 and the opening 31, the second optical film 30 can be positioned on the substrate 20. In one embodiment, the substrate 10 may have another protrusion (not shown), and the main body 20a of the first optical film 20 may also have an opening similar to the opening 31 (not shown), so the first optical film 20 can be positioned on the substrate 10 through its own opening and the other protrusion. In addition, in another embodiment, the edge of the substrate 10 may have a plurality of protrusions (not shown), and the first optical film 20 and / or the second optical film 30 may also have a plurality of openings (not shown) corresponding to the protrusions. In other words, the number of the protrusions and the openings may be one or more, and the present application has no particular limitation.

[0059] Then match Figure 1C The details of the interference between the engaging portion 21 of the first optical film 20 and the second optical film 30 are described, and please also refer to Figure 1A and Figure 1B .

[0060] like Figure 1C As shown, from the cross-sectional view, the engaging structure 213 is located between the first portion 211 and the second portion 212, and at least a portion of the main body 30a of the second optical film 30 can be inserted into the engaging structure 213 and sandwiched between the first portion 211 and the second portion 212. Figure 1A and 1B It can be seen that a portion of the surface 30t of the second optical film 30 will contact the first portion 211, and a portion 30b of the other surface of the second optical film 30 will contact the second portion 212. It can be seen that in one embodiment, the first portion 211 and the second portion 212 are separated and arranged in the first direction Y, and the engagement direction of the first portion 211 or the second portion 212 and the second optical film 30 (that is, the normal direction of the contact surface between the first portion 211 or the second portion 212 and the second optical film 30) can be perpendicular to the first direction Y, for example, the engagement direction can be parallel to the third direction Z, and is not limited thereto. Therefore, the first optical film 20 and the second optical film 30 can be engaged with each other and interfere with each other.

[0061] In one embodiment, the first portion 211 has a first maximum length L1 in the second direction X, and the second portion 212 has a second maximum length L2 in the second direction X, wherein the first maximum length L1 and the second maximum length L2 can be measured from the engaging structure 213 as a starting point (i.e., the intersection of the engaging structure 213 and the main body 20a) and along the second direction X, and the first maximum length L1 is not equal to the second maximum length L2. In one embodiment, the first maximum length L1 can be less than the second maximum length L2, but is not limited thereto.

[0062] Therefore, the first optical film 20 and the second optical film 30 can interfere with each other and be fixed, so that the first optical film 20 or the second optical film 30 can be reduced from rotating and / or turning relative to the substrate 10, and the chance of the substrate 10 being exposed can be reduced. Therefore, the optical quality of the electronic device 1 of the present application can be improved.

[0063] The protrusion 11 of the substrate 10 and the opening 31 of the second optical film 30 of the present application may also have different implementation forms. FIG. 3A to FIG. 3C is a schematic diagram of the protrusion 11 and the opening 31 of different embodiments of the present application, and please also refer to Figure 1A to Figure 2 .

[0064] exist Figure 3A In the embodiment, the protrusion 11 is, for example, a circular protrusion, and the opening 31 may be a circular opening having a size equal to or slightly larger than that of the protrusion 11 .

[0065] exist Figure 3B In the embodiment, the protrusion 11 is, for example, an elliptical protrusion, and the opening 31 can be an elliptical opening equal to or slightly larger than the size of the protrusion 11. The design of the elliptical protrusion and the elliptical opening can reduce the chance of the second optical film 30 rotating relative to the substrate 10, but is not limited thereto.

[0066] exist Figure 3C In the embodiment, the protrusion 11 is a rectangular protrusion, for example, and the opening 31 can be a rectangular opening equal to or slightly larger than the size of the protrusion 11. The design of the rectangular protrusion and the rectangular opening can reduce the chance of the second optical film 30 rotating relative to the substrate 10, but is not limited thereto.

[0067] In addition, the protrusion 11 and the opening 31 may also have more different shapes, as long as the shapes and sizes of the two correspond to each other and can achieve the above-mentioned positioning and / or rotation reduction effect. In addition, the first optical film 20 may also have an opening 31 similar to the above-mentioned second optical film 30, so that the first optical film 20 can be positioned on the substrate 10 through the above-mentioned mechanism and / or the chance of the first optical film 20 rotating relative to the substrate 10 can be reduced, but it is not limited thereto.

[0068] In one embodiment, the present invention can at least compare the presence or configuration relationship of an object by means of mechanical observation, for example, using the presence or configuration relationship of the object as evidence of whether the operation of the object falls within the scope of protection of the present application, but is not limited thereto.

[0069] The details or features of the various embodiments of the present application may be mixed and matched as desired as long as they do not violate the spirit of the invention or conflict with each other.

[0070] Therefore, the first optical film 20 and the second optical film 30 of the electronic device 1 of the present application have specially designed structural features, which can solve the problems of the prior art.
