Description

Technical Field

[0001] The utility model relates to the technical field of backlight glue iron frames, in particular to an anti-deformation backlight glue iron frame. Background Technique

[0002] With the development of technology, there are more and more electronic display devices, and people's quality requirements for electronic display devices are also getting higher and higher. Electronic display devices, such as mobile phones and tablets, the display device itself in the electronic display device is transparent and does not have a light-emitting function, and it needs to rely on the backlight on the back side to assist in displaying the picture. In the backlight, a light guide plate and optical film sheets need to be fixed inside a glue iron frame, and the light emitted by the light source is irradiated onto the display module after being processed by the optical film sheets to display the picture.

[0003] The glue iron frame includes a glue frame and an iron frame. The glue frame is fixed inside the iron frame, and the optical film sheets and the light guide plate are fixed inside the glue frame. Patent Application No. CN202321104800.9 discloses a backlight glue iron frame, a backlight module and a display module for preventing the deformation of the glue frame, which includes a glue frame and an iron frame. The glue frame is arranged inside the iron frame. The glue frame is a rectangular frame, and "convex"-shaped nail columns are arranged around the glue frame. A bayonet matching the nail columns is arranged on the side of the iron frame. The nail columns pass through the bayonet and extend to the outside of the iron frame and fit with the outside of the iron frame to traction the side of the glue frame. In this scheme, the outer part of the nail column is used to fit with the iron frame, and the nail column pulls the glue frame, so that the glue frame is closely attached to the iron frame. The glue frame uses the hard iron frame as a traction support to achieve the purpose of stably fixing the glue frame and effectively prevent the glue frame from deforming due to extrusion and collision. However, in this structural design, the nail columns need to extend to the outside of the iron frame, which increases the frame width and is not conducive to the development needs of narrow-frame display devices. At the same time, during installation, the nail columns need to be pressed into the bayonet from the opening groove, and the assembly is relatively troublesome, greatly reducing the production efficiency and increasing the production cost.

[0038] When assembled with the optical film, the backlight film is mounted on the bottom plate 3 , and the periphery of the optical film is positioned by the rubber frame 1 .

[0039] In order to further improve the stability of the connection between the plastic frame 1 and the iron frame 2, the plastic frame 1 and the iron frame 2 are integrally formed, that is, the plastic frame 1 and the iron frame 2 are directly injection molded together. In addition, the plane size of the bottom plate 3 is consistent with the outer plane size of the plastic frame 1, and the frame around the bottom plate 3 on the iron frame 2 is reduced, which can greatly reduce the width of the frame, making it easy to realize the narrow frame design of the display device, and is mainly used in full-screen mobile phones.

[0040] The thickness of the insert piece 4 is 1 / 3-1 / 2 of the wall thickness of the rubber frame 1 . Preferably, the thickness of the insert piece 4 is 1 / 2 of the thickness of the rubber frame 1 to ensure the strength of the insert piece 4 .

[0041] In this embodiment, a protrusion 6 is provided on the side of the plug 4, and a slot 7 is provided on the side of the rubber frame 1. The protrusion 6 is provided on the outer side of the plug 4, and the slot 7 is also provided on the outer side of the rubber frame 1. After the plug 4 is inserted into the slot 5, the protrusion 6 is engaged with the slot 7, and the protrusion 6 is used to limit the vertical direction of the connection between the rubber frame 1 and the iron frame 2 to prevent the rubber frame 1 from vertically offset relative to the iron frame.

[0046] The working principle of the anti-deformation backlight adhesive iron frame provided by the present invention: After the iron frame is prepared, the iron frame and the rubber frame 1 are integrally injection-molded into an integral structure. Alternatively, the rubber frame 1 can be injection-molded separately, and the iron frame and the rubber frame 1 are connected together by means of insertion. By providing insertion pieces 4 on the bottom plate 3 of the iron frame 2 and slots 5 on the side wall of the rubber frame, when the rubber frame and the iron frame 2 are assembled, the insertion pieces 4 are inserted into the slots 5 to fix the rubber frame and the iron frame 2 together, and the insertion pieces 4 are used to limit the inner and outer directions of the side wall of the rubber frame to prevent the rubber frame from deforming inward and outward. Moreover, the outer frame of the iron frame 2 is not used, reducing the frame width, which is suitable for use in narrow-frame display devices. In addition, the hard insertion pieces 4 are inserted into the soft rubber frame 1, which is convenient for assembly, has high production efficiency, also reduces the production preparation cost, and improves the product competitiveness.
