Description of the Related Art
In view of improving a strength of a device and preventing dust, an adhesive tape may be used in a backlight module. A combination of the adhesive tape and a frame or the like of the backlight module can not only play a sealing effect, but also improve a bonding strength. However, in such a backlight module, there may be a phenomenon of light leakage between the adhesive tape and a display panel.
In a first aspect, in an embodiment of the present disclosure, there is provided a plastic frame comprising a frame body, wherein an upwardly extending protrusion is provided along an inner edge of the frame body at an inner side of the frame body, and a mounting surface is provided on an upper surface of the frame body at an outer side of the protrusion.
Further, the mounting surface is shaped such that a thickness of a portion of the frame body at the mounting surface is less than a thickness of a portion of the frame body at the protrusion.
Further, an inwardly extending carrying portion is provided at an inner side of the plastic frame.
Further, the carrying portion is shaped such that an upper surface of the carrying portion is lower in a vertical direction than an upper surface of the protrusion.
In a second aspect, in an embodiment of the present disclosure, there is provided a backlight module comprising a front frame, a display panel and an adhesive tape, wherein the backlight module further comprises the plastic frame according to any one of the above-described embodiments,
wherein the front frame covers the mounting surface, the display panel is carried on an inner side of the plastic frame, the adhesive tape extends from an upper surface of the front frame to an upper surface of the protrusion and is adhered to the upper surface of the front frame and the upper surface of the protrusion, and the adhesive tape further extends from the upper surface of the protrusion to an upper surface of the display panel and is adhered to the upper surface of the display panel.
Further, the upper surface of the protrusion is flush with the upper surface of the front frame.
Further, an inwardly extending carrying portion is provided at an inner side of the plastic frame, and the display panel is carried on the carrying portion.
Further, the carrying portion is shaped such that an upper surface of the carrying portion is lower in a vertical direction than the upper surface of the protrusion.
Further, the upper surface of the display panel is flush with the upper surface of the protrusion.
In a third aspect, in an embodiment of the present disclosure, there is provided a display device comprising the backlight module according to any one of the above-described embodiments.
In order to more clearly illustrate the technical solutions of the embodiments of the present disclosure, the drawings, which are used in the description of the embodiments, will be briefly described below. It will be apparent that the drawings in the following description only represent some embodiments of the present disclosure. Other drawings may be obtained by those skilled in the art according to these drawings without creative efforts.
In order to more clearly provide the objectives, technical solutions and advantages of the embodiments of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below, with reference to the accompanying drawings in the embodiments of the present disclosure. It will be apparent that the described embodiments only represent a part of the present disclosure, rather than all the embodiments of the present disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative efforts fall within the scope of the present disclosure.
In order to at least partially address the drawbacks in the related art, the present disclosure provides a plastic frame, a backlight module and a display device capable of solving the light leakage problem between the adhesive tape and the display panel.
As shown in
Further, at a side edge of the protrusion 11, a width of the protrusion 11 in an extension direction of the display panel 4 is between ⅕ and ⅓ of a width of the front frame 2 corresponding to the side edge. Such a width of the protrusion 11 on one hand provides a sufficient adhesion area for the adhesive tape 3 so as to provide a sufficient restraining force when the front frame 2 warps outwardly, on the other hand ensures that the front frame 2 can be firmly engaged with the plastic frame 1. It should be noted that an excessive width of the protrusion 11 will cause an engagement surface of the front frame 2 and the plastic frame 1/the adhesive tape 3 to be excessively small to affect the fixing of the front frame 2.
In order to facilitate positioning the display panel 4 and the plastic frame 1, as shown in
As an example, a vertical distance between the upper surface of the carrying portion 12 and the upper surface of the protrusion 11 is greater than a vertical distance between the mounting surface 13 and the upper surface of the protrusion 11. In addition, the carrying portion 12 has a lower surface which is parallel to the upper surface of the carrying portion, and a width of the upper surface of the carrying portion in the extension direction of the display panel 4 is less than a width of the lower surface of the carrying portion in the extension direction of the display panel 4. A height of the carrying portion 12 is greater than the vertical distance between the mounting surface 13 and the upper surface of the protrusion 11.
Further, the upper surface of the display panel 4 is flush with the upper surface of the protrusion 11, thereby avoiding any height difference between the front frame 2 and the display panel 4, and optimizing the overall structure.
In addition, in an embodiment of the present embodiment, there is also provided a display device including the above-described backlight module. By providing the backlight module, it is possible for the display panel 4 to ensure that no light leakage occurs from the adhesive tape 3.
According to the above-described technical solutions, the embodiments of the present disclosure have improved the structure of the plastic frame, in particular, an upwardly extending protrusion is provided along an inner edge of a frame body of the plastic frame at an inner side of the frame body, and a mounting surface is provided on an upper surface of the frame body at an outer side of the protrusion. Further, a front frame covers the mounting surface, a display panel is carried on an inner side of the plastic frame, an adhesive tape extends from an upper surface of the front frame to an upper surface of the protrusion and is adhered to the upper surface of the front frame and the upper surface of the protrusion, and the adhesive tape extends from the upper surface of the protrusion to an upper surface of the display panel and is adhered to the upper surface of the display panel. Since the protrusion is provided, it is ensured that the adhesive tape can be adhered to the plastic frame. In this way, if the front frame warps outwardly, only a portion of the adhesive tape adhered to the plastic frame may be pulled, thus it ensures direct adhering widths of the adhesive tape and the display panel and ensures that no light leakage occurs from the adhesive tape.
It can be seen that the embodiments of the present disclosure provides an ingenious structure, and can ensure that no light leakage occurs between the display panel 4 and the adhesive tape 3.
In the description of the embodiments of the present disclosure, it should be noted that the extension of the protrusion 11 toward an adhesion surface of the plastic frame 1 adhered to the front frame 2 refers to an “upward” extension, a side located close to the display panel 4 refers to an “inner” side, and a side located away from the display panel 4 refers to an “outer” side. The orientation description is merely for facilitating and simplifying the description of the embodiments of the present disclosure, rather than indicating or implying that the interested means or elements must have a specific orientation or be constructed and operated in a specific orientation, therefore it should not be construed as being limitative to the present disclosure.
