DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative effort fall within the protection scope of the present application.

[0042] In the embodiments of the present application, it should be noted that, in this document, relational terms such as first and second and the like are used solely to distinguish one entity or action from another entity or action, without necessarily requiring or implying any actual such relationship or order between or among the entities or actions.

[0043] Moreover, the terms "comprising", "comprises", "comprised", "comprising" or any other variation thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element preceded by "comprises a" does not, without more constraints, foreclose the existence of additional identical elements in the process, method, article, or apparatus that comprises the recited element.

[0044] In the description of the embodiments of the present application, the words "example" or "for example" or the like are used to mean "an example of" or "for example". Any embodiment or design solution described as "example" or "for example" in the embodiments of the present application is not interpreted as being more preferred or having more advantages than another embodiment or design solution. The words "example" or "for example" or the like are intended to present a relative concept in a clear manner.

[0045] The embodiments of the present application provide a display device to reduce the cost of atmosphere lamp. The display device can be any product or component with display function, such as liquid crystal display panel, electronic paper, mobile phone, tablet computer, television, display, notebook computer, digital photo frame, navigator, etc. The specific structure of the display device is not limited in the embodiments of the present application.

[0046] Please refer to Figure 1 , Figure 2 and Figure 3The display device comprises a housing 100 and an atmosphere lamp assembly 200. The atmosphere lamp assembly 200 is arranged on the housing 100, and the atmosphere lamp assembly 200 comprises a light guide plate 21 and a light source module 22. The light guide plate 21 comprises a side surface 211, a front surface 212 and a back surface 213. The side surface 211 is located at the outer circumferential side of the light guide plate 21, and the side surface 211 is used for allowing first light generated by the light source module 22 to be incident into the light guide plate 21. At least one of the front surface 212 and the side surface 211 is provided with an exit structure 214, so that the first light can be emitted from the front surface 212 to the outside of the housing 100 through the exit structure 214.

[0047] Therefore, the light source module 22 only needs to generate the first light incident from the side surface 211 to the light guide plate 21, so that the large-area light emission of the front surface 212 of the light guide plate 21 can be realized. In this way, the light source module 22 can not be arranged in the same area as the back surface 213 of the light guide plate 21, and thus the cost of the light source module 22 can be reduced.

[0048] The above is a general introduction to the technical solutions of the embodiments of the present application. The embodiments of the present application will be further described below in combination with the exit structure 214.

[0049] In some embodiments, the exit structure 214 comprises at least one of a protruding structure and a recessed structure.

[0050] For example, after the first light is incident into the light guide plate 21, the first light propagates in the light guide plate 21 by means of total reflection, so that the first light is repeatedly reflected between the front surface 212 and the back surface 213. When the first light in the light guide plate 21 is incident on the exit structure 214, the corresponding protruding structure and / or recessed structure destroys the total reflection of the first light, so that the first light is emitted from the front surface 212.

[0051] In the embodiments of the present application, the association relationship of the associated objects described by “and / or” can represent three kinds of relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character “ / ”, if not specially stated, generally represents an “or” relationship between the front and rear associated objects.

[0052] That is, the exit structure 214 can only comprise a protruding structure, can only comprise a recessed structure, or can simultaneously comprise a protruding structure and a recessed structure, and the embodiments of the present application do not limit this.

[0053] In some embodiments, the recessed depth of the recessed structure is less than or equal to 1 millimeter, so that the brightness of the light emitted from the front surface 212 can be improved.

[0054] For example, the recessed structure has a recessed depth of 0.1 mm, 0.24 mm, 0.35 mm, 0.5 mm, 0.66 mm, 0.74 mm, 0.8 mm, 0.92 mm, or 1 mm, which is not limited in the embodiments of the present application.

[0055] In some embodiments, the exit structure 214 can be shaped by engraving, such as laser engraving. Of course, in some other embodiments, the exit structure 214 can also be imprinted by molding, which is not limited in the embodiments of the present application.

[0056] Therefore, in the actual production process, only the plurality of exit structures 214 arranged to form a predetermined pattern or text is needed, so that after the light source module 22 works, the first light can be emitted from the front surface 212 at the exit structure 214, so that the user can see the predetermined pattern or text from the front surface 212.

[0057] In some embodiments, the exit structure 214 is arranged on the back surface 213, so as to improve the brightness of the light emitted from the front surface 212.

[0058] Of course, in some other embodiments, the exit structure 214 can also be arranged on the front surface 212, as long as the first light can be emitted from the front surface 212 through the exit structure 214, which is within the protection scope of the present application, and the embodiments of the present application are not limited.

[0059] The above is the introduction of the exit structure 214 of the technical solution of the embodiments of the present application, and the embodiments of the present application will be introduced below in combination with the shell 100.

[0060] In some embodiments, the shell 100 is provided with a light exit area 11, so that the first light can be emitted from the light exit area 11 to the outside of the shell 100. Therefore, it can also be understood that the atmosphere lamp assembly 200 can be at least partially arranged in the shell 100 to provide certain protection for the atmosphere lamp assembly 200 by the shell 100.

[0061] The light exit area 11 can be the same as the display surface of the display device, or can be different, which is not limited in the embodiments of the present application.

[0062] For example, the side where the display surface of the display device is located is the front view surface of the display device, and the side away from the display surface of the display device is the rear view surface of the display device, and the light exit area 11 can be arranged on the rear view surface of the display device.

[0063] In some embodiments, the atmosphere lamp can further include a light shielding piece 23, which at least partially shields the side of the light source module 22 facing the light exit area 11.

[0064] It can be understood that, since the light source module 22 is configured to inject the first light into the light guide plate 21 from the side surface 211 of the light guide plate 21, the light source module 22 is also likely to generate the second light directly emitted to the light emitting area 11 from the outer peripheral side of the light guide plate 21, and further cause the second light to be directly emitted from the edge of the light emitting area 11 to form light leakage. Then, the light blocking member 23 can be used to block the side of the light source module 22 facing the light emitting area 11, so as to improve the light leakage phenomenon at the edge of the light emitting area 11, and thus improve the aesthetics of the atmosphere lamp.

[0065] In some embodiments, the light source module 22 is connected with the light blocking member 23. Further, the light source module 22 can be installed through the light blocking member 23, and meanwhile, the positional error between the light source module 22 and the light blocking member 23 can be reduced, so as to ensure that the light blocking member 23 can accurately block the side of the light source module 22 facing the light emitting area 11.

[0066] The light source module 22 and the light blocking member 23 can be detachably connected, so as to facilitate the disassembly and maintenance of the light source module 22 and the light blocking member 23. Of course, the light source module 22 and the light blocking member 23 can also be non-detachably connected, which is not limited in the embodiments of the present application.

[0067] For example, the light source module 22 can be detachably connected with the light blocking member 23. For example, the light source module 22 can be detachably connected with the light blocking member 23 in a clamping manner, a screwing manner or a magnetic attraction manner, which is not limited in the embodiments of the present application.

[0068] For example, the light source module 22 can be detachably connected with the light blocking member 23. For example, the light source module 22 can be detachably connected with the light blocking member 23 in a clamping manner, a screwing manner or a magnetic attraction manner, which is not limited in the embodiments of the present application. Figure 4 Figure 5 For example, the light source module 22 can be detachably connected with the light blocking member 23. For example, the light source module 22 can be detachably connected with the light blocking member 23 in a clamping manner, a screwing manner or a magnetic attraction manner, which is not limited in the embodiments of the present application.

[0069] Further, the light blocking member 23 can block the second light generated by the light source module 22 from directly emitting to the light emitting area 11 through the first side wall 231. Meanwhile, the light blocking member 23 can also provide support for the side of the light source module 22 away from the light guide plate 21 through the second side wall 232, so as to improve the stability and reliability of the installation of the light source module 22.

[0070] For example, the light source module 22 can be detachably connected with the light blocking member 23. For example, the light source module 22 can be detachably connected with the light blocking member 23 in a clamping manner, a screwing manner or a magnetic attraction manner, which is not limited in the embodiments of the present application.

[0071] ​Exemplarily, the first clamping portion 233 can be located at a side of the light source module 22 away from the light emitting area 11, so that the light source module 22 is clamped and fixed by the first clamping portion 233 and the first side wall 231 together.

[0072] The first clamping portion 233 can include a plurality of clamping claws arranged along the extension direction of the light source module 22, so as to realize clamping and fixing of the light source module 22 at multiple positions, thereby improving the stability and reliability of the installation of the light source module 22.

[0073] Exemplarily, the light source module 22 can include a lamp strip. The substrate of the lamp strip extends along one side of the light guide plate 21 in the circumferential direction. Correspondingly, the plurality of clamping claws are arranged at the edge of the substrate away from the light emitting area 11, and the first side wall 231 is located at the side of the substrate facing the light emitting area 11, so that the substrate is clamped and fixed by the plurality of clamping claws and the first side wall 231 together.

[0074] In some embodiments, the first side wall 231 is provided with a second clamping portion 234, and one end of the light source module 22 facing the light emitting area 11 is clamped between the second clamping portion 234 and the second side wall 232. Thus, better fixation can be provided for the one end of the light source module 22 facing the light emitting area 11.

[0075] The number of the second clamping portions 234 can be multiple, and the plurality of second clamping portions 234 are arranged along the extension direction of the light source module 22, so as to realize clamping and fixing of the light source module 22 at multiple positions, thereby improving the stability and reliability of the installation of the light source module 22.

[0076] Exemplarily, the light source module 22 can include a lamp strip. The substrate of the lamp strip extends along one side of the light guide plate 21 in the circumferential direction. Correspondingly, the plurality of second clamping portions 234 are arranged at the edge of the substrate facing the light emitting area 11, so that the substrate is clamped and fixed by the plurality of second clamping portions 234 and the first side wall 231 together.

[0077] Please continue to refer to Figure 6 and Figure 7 In some embodiments, the outer end edge of the light guide plate 21 is provided with a positioning groove 215, and the second clamping portion 234 is at least partially located in the positioning groove 215. Thus, the second clamping portion 234 can also be reused for positioning of the light guide plate 21 and the light shielding piece 23, so that the light shielding piece 23 and the light source module 22 connected to the light shielding piece 23 can be more accurately installed to the preset position of the light guide plate 21.

[0078] In some embodiments, the light shielding member 23 further comprises two third side walls 235, and the first side wall 231 and the second side wall 232 are connected between the two third side walls 235, so that the first side wall 231, the second side wall 232 and the two third side walls 235 form a mounting space on the side of the first side wall 231 away from the light emitting area 11, and the light source module 22 is at least partially arranged in the mounting space.

[0079] For example, the light emitting area 11 is located at the rear side of the light source module 22, and the first side wall 231 extends in the left-right direction. The first clamping portion 233 and the first side wall 231 can be used to clamp and fix the light source module 22 in the front-rear direction, the two third side walls 235 can be used to fix the light source module 22 in the left-right direction, and the second clamping portion 234 and the second side wall 232 can be used to fix the light source module 22 in the up-down direction, thereby ensuring the stability and reliability of the installation of the light source module 22.

[0080] Please continue to refer to Figure 8 In some embodiments, the atmosphere lamp further comprises a decorative member 24, and the decorative member 24 is at least partially located on the light emitting side of the light guide plate 21, thereby playing a certain decorative effect on the light guide plate 21.

[0081] For example, the light transmittance of the decorative member 24 is less than that of the light guide plate 21. Further, when the light source module 22 does not emit light, the decorative member 24 can provide better shielding for the exit structure 214 on the light guide plate 21 to improve the aesthetics of the atmosphere lamp assembly 200, and after the light source module 22 emits light, the first light can be transmitted from the decorative member 24 to display the preset pattern or text.

[0082] In some embodiments, the light transmittance of the decorative member 24 is greater than or equal to 45% and less than or equal to 70%. In this way, it can be avoided that the light transmittance of the decorative member 24 is too small to cause insufficient brightness of the atmosphere lamp assembly 200 when it works, and it can also be avoided that the light transmittance of the decorative member 24 is too large to cause the user to directly observe the exit structure 214 when the atmosphere lamp assembly 200 does not work.

[0083] For example, the light transmittance of the decorative member 24 can be 45%, 45.5%, 47%, 48.34%, 49%, 50%, 51.2%, 55%, 56.4%, 59.3%, 60%, 61.2%, 62%, 65%, 67%, 68.31%, 69%, 69.55% or 70%, which is not limited in the embodiments of the present application.

[0084] In some embodiments, the light transmittance of the decorative member 24 is greater than or equal to 50% and less than or equal to 60%.

[0085] In some embodiments, the first mounting cavity 12 is formed between the decorative piece 24 and the housing 100, and the ambient light assembly 200 is arranged in the first mounting cavity 12. Thus, the light source module 22 and the light guide plate 21 and other components can be mounted through the connection between the decorative piece 24 and the housing 100.

[0086] In some embodiments, the first mounting cavity 12 can be formed in the housing 100, and the opening of the first mounting cavity 12 forms the light emitting area 11. The decorative piece 24 is connected to the housing 100 to close the first mounting cavity 12 (or the light emitting area 11).

[0087] Correspondingly, the light shielding piece 23 can be clamped between the decorative piece 24 and the housing 100. For example, one end of the first side wall 231 of the light shielding piece 23 abuts against the bottom wall of the first mounting cavity 12, and the other end abuts against the decorative piece 24.

[0088] In some embodiments, the light guide plate 21 abuts against the bottom wall of the first mounting cavity 12. The bottom wall of the first mounting cavity 12 can also be provided with a recess 13, and the end of the light source module 22 away from the light emitting area 11 and the end of the first side wall 231 away from the light emitting area 11 are accommodated in the recess 13. Thus, the housing 100 does not need to be recessed too deep into the interior of the housing 100 at the light guide plate 21, so that more space can be reserved in the interior of the housing 100 for mounting components inside the display device.

[0089] In some embodiments, the decorative piece 24 can be detachably connected to the housing 100. For example, the decorative piece 24 can be clamped to the housing 100, or the decorative piece 24 can be screwed to the housing 100, or the decorative piece 24 can be magnetically fixed to the housing 100, and the present application does not limit this. Thus, the decorative piece 24 can be conveniently detached for subsequent maintenance of the ambient light assembly 200 during use of the display device.

[0090] In some embodiments, the decorative piece 24 can include a shielding part 241 and a connecting part 242, and the connecting part 242 is arranged around the shielding part 241. The connecting part 242 is clamped to the housing 100, so that the shielding part 241 closes the light emitting area 11.

[0091] Then, a mounting process of the ambient light assembly 200 can be as follows:

[0092] First, the light guide plate 21 is loaded into the first mounting cavity 12 through the light emitting area 11.

[0093] Then, the light source module 22 is clamped to the light shielding piece 23.

[0094] Then, the light shielding member 23 installed to the light source module 22 is loaded into the first installation cavity 12 through the light exit area 11, so that the second clamping portion 234 of the light shielding member 23 is clamped to the positioning groove 215 of the light guide plate 21.

[0095] Finally, the decorative member 24 is clamped to the shell 100 to close the light exit area 11.

[0096] Therefore, the display device has the advantage that the atmosphere lamp assembly 200 is easy to assemble.

[0097] In some embodiments, the shell 100 is provided with the first installation cavity 12 and the second installation cavity 14, and the openings of the first installation cavity 12 and the second installation cavity 14 face opposite directions. The display device further comprises a backlight module arranged in the second installation cavity 14.

[0098] Therefore, the side where the opening of the second installation cavity 14 is located is the front surface of the display device, and the side where the opening of the first installation cavity 12 is located, or the light exit side of the atmosphere lamp assembly 200, is the rear surface of the display device.

[0099] In some embodiments, the display device further comprises a main control circuit board, and the light guide plate 21 is arranged around the main control circuit board. Therefore, the space around the main control circuit board can be fully utilized to arrange the atmosphere lamp assembly 200 with a larger area.

[0100] For example, the shell 100 is further provided with a third installation cavity 15, the first installation cavity 12 is arranged around the outer circumferential side of the third installation cavity 15, and the main control circuit board is arranged in the third installation cavity 15, so that the light guide plate 21 is arranged around the main control circuit board.

Therefore, the features defined as “first” and “second” can explicitly or implicitly include one or more features. In the description of the present application, the meaning of “a plurality of” is two or more, unless otherwise specifically limited.

[0102] In the above embodiments, the description of each embodiment focuses on different aspects, and the parts not described in detail in a certain embodiment can be referred to the related description of other embodiments.

[0103] The embodiments, implementation manners and related technical features of the present application can be combined or replaced with each other without conflict.

[0104] The above are only the preferred embodiments of the present application, and do not limit the present application in any form, but any simple modification, equivalent change and modification made to the above embodiments without departing from the technical solution of the present application and according to the technical essence of the present application are still within the scope of the technical solution of the present application.
