Abstract
Description
Technical Field
[0001] The present application belongs to the field of display technology, and in particular relates to a backlight source bearing structure, a liquid crystal display module and an electronic device. Background Art
[0002] The liquid crystal display module provided by the related art generally includes a BL (backlight source), and the backlight source generally uses a plastic frame and an iron frame as its bearing structure. Among them, the plastic frame and the iron frame are integrally injection molded (referred to as "plastic-iron integration"), thus forming a bearing structure for supporting the backlight source.
[0003] However, when the LCD module adopting this bearing structure is subjected to mechanical extreme condition experiments (such as directional drop, roller, micro-drop, etc.), the glue and iron are easily separated, resulting in white spots, white lumps, uneven light leakage and other undesirable phenomena on the BL.

[0008] Bosses for embedding into the via holes are arranged around the rubber frame.
[0009] In some embodiments, the inward bending angle of the side portion corresponding to each segment is greater than or equal to 110° and less than 180°.
[0010] In some embodiments, the four corners of the iron frame are stretched to form a half-wrapped structure, and the stretching height is greater than or equal to 1.2 mm.

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0027] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.
[0028] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0029] In order to illustrate the technical solution described in this application, a specific embodiment is provided below for illustration.
[0030] See also Figures 1 to 8 As shown, the embodiment of the present application provides a backlight source bearing structure 10, including a plastic frame 11 and an iron frame 12, and the plastic frame 11 and the iron frame 12 are integrally injection molded.
[0031] The iron frame 12 is provided with a double folded edge structure 121 around it, which can increase the strength of the BL product and also increase the grip between the iron frame 12 and the plastic frame 11, thereby preventing the iron frame 12 from separating from the plastic frame 11. A via 122 is provided on the double folded edge structure 121, and the via 122 is used to cooperate with the boss 111 around the plastic frame 11. For example, the boss 111 is embedded in the via 122, which can play an auxiliary role in gripping the glue and further prevent the iron frame 12 from separating from the plastic frame 11.
[0032] One side of the iron frame 12 corresponding to the light source position 112 is divided into a plurality of segments 124, and the side portion 1241 corresponding to each segment is bent inwardly to form a barb shape. It should be noted that, because the glue position of the light source position 112 where the glue frame 11 is used to place the light source (such as LED) is relatively thin, the side portion of the iron frame 12 corresponding to the light source position 112 cannot be made into a double folded edge, and the probability of the separation of the glue frame 11 and the iron frame 12 is relatively high. For this reason, the embodiment of the present application divides the side portion into a plurality of segments 124, and the side portion 1241 corresponding to each segment is bent inwardly to form a barb shape, so that the material is more firmly grasped, thereby further avoiding the separation of the iron frame 12 and the glue frame 11. As an example, the angle of the inward bending of the side portion 1241 corresponding to each segment is greater than or equal to 110°, and less than 180°.
[0033] The backlight source bearing structure 10 can avoid the separation of the iron frame 12 and the plastic frame 11 by designing the double folded edge structure 121, the barb shape, the boss 111 and the via 122, and effectively improve the stability of the mechanical reliability performance experiment of the whole module under extreme conditions.
[0034] In some embodiments, the four corners of the iron frame 12 are stretched to form a half-wrapped structure 123 , and the stretching height is greater than or equal to 1.2 mm, so that the overall strength of the iron frame 12 can be increased.
[0035] In other embodiments of the present application, a liquid crystal display module is provided, comprising the backlight source supporting structure 10 provided in any of the above embodiments.
[0036] In some other embodiments of the present application, an electronic device is provided, comprising the liquid crystal display module provided in the above embodiments. As an example, the electronic device is a mobile phone.
[0037] The embodiments described above are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
