Description
Technical Field
[0001] The utility model relates to the technical field of liquid crystal display, and more specifically, to a liquid crystal display screen sharing an iron frame. Background Art
[0002] In the traditional structural design of a liquid crystal display module, generally, after the TFT glass is made into FOG, it is wrapped by two upper and lower iron frames. Since the outer dimensions of the two upper and lower iron frames in the prior art are different, separate molds need to be opened, resulting in a relatively high production cost for the two iron frames. Especially for some structures with fewer production models, the mold cost allocated to each iron frame is very high, thus increasing the cost of the entire liquid crystal display screen and reducing the competitiveness of the product. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is how to make the structures of the two upper and lower iron frames the same, so that only one set of molds is needed to produce the two upper and lower iron frames, which is equivalent to doubling the number of iron frame products produced by one set of molds. Therefore, the cost allocated to each iron frame is reduced, thereby reducing the cost of the liquid crystal display screen and improving the competitiveness of the product.
[0004] The technical problem to be solved by the utility model is realized through the following technical solutions:
[0005] To solve the above technical problem, the utility model provides a liquid crystal display screen sharing an iron frame, which includes an iron frame. The iron frame includes a bottom plate. The bottom plate includes four rectangular sides, and the four rectangular sides are sequentially connected end to end to form a square shape. An extension part is provided on the outer side of half of each rectangular side. An outer side wall is provided at the edge of each extension part, and an inner side wall is provided at the edge of each rectangular side without an extension part. A card slot is provided on the outer side wall, and a buckle corresponding to the position of the card slot is provided on the outer side of the inner side wall. There are two iron frames, which are respectively an upper iron frame and a lower iron frame that are buckled with each other.
[0006] As a preferred implementation manner of the liquid crystal display screen sharing an iron frame provided by the utility model, a notch is provided in the middle of each rectangular side.
[0007] As a preferred implementation manner of the liquid crystal display screen sharing an iron frame provided by the utility model, the notch widths of three of the rectangular sides are equal, and the notch width of the other rectangular side is greater than the notch widths of the three rectangular sides.
[0008] As a preferred implementation manner of the liquid crystal display screen sharing an iron frame provided by the utility model, the width of the extension part is greater than or equal to the thickness of the inner side wall.
[0009] As a preferred embodiment of the shared iron frame liquid crystal display provided by the present utility model, each of the elongation parts is arranged on the left half of each rectangular side.
[0010] As a preferred embodiment of the shared iron frame liquid crystal display provided by the present utility model, a TFT module is arranged in the space formed by the two iron frames buckled together. The TFT module includes a lower polarizer, a lower substrate, an upper substrate, and an upper polarizer which are sequentially stacked from bottom to top.
[0011] As a preferred embodiment of the shared iron frame liquid crystal display provided by the present utility model, double-sided adhesive is arranged on the bottom plate of the lower iron frame, and the lower polarizer is fixedly adhered to the bottom plate of the lower iron frame through the double-sided adhesive.
[0012] As a preferred embodiment of the shared iron frame liquid crystal display provided by the present utility model, the lower substrate is longer than the upper substrate and extends outwards to form a step, and a driving IC and an FPC are bonded to the upper surface of the lower substrate at the step.
[0013] As a preferred embodiment of the shared iron frame liquid crystal display provided by the present utility model, a shielding paper is arranged on the upper surface of the FPC.
[0014] As a preferred embodiment of the shared iron frame liquid crystal display provided by the present utility model, components are arranged on the FPC, and an insulating paper is arranged on the lower surface of the shielding paper at the position of the components.
[0015] The present utility model has the following beneficial effects:
[0016] Since the outer wall is arranged at the edge of the elongation part, and the inner wall is arranged at the edge of the rectangular side without the elongation part, the outer wall and the inner wall can be staggered. Then the two iron frames are buckled together, one on top of the other. The buckle of the upper iron frame is stuck on the slot of the lower iron frame, and the buckle of the lower iron frame is stuck on the slot of the upper iron frame, so as to achieve fixation. In this way, the structures of the upper and lower iron frames are the same, so only one set of molds is needed to produce the upper and lower iron frames, that is, the two iron frames share one set of molds, which is equivalent to doubling the number of iron frame products produced by one set of molds. The cost per iron frame is thus reduced, thereby reducing the cost of the liquid crystal display and improving the competitiveness of the product. BRIEF DESCRIPTION OF THE DRAWINGS

In the description of the present utility model, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically defined.
[0029] The present utility model provides a liquid crystal display screen sharing an iron frame, which includes an iron frame. The iron frame includes a bottom plate. The bottom plate includes four rectangular sides, and the four rectangular sides are sequentially connected end to end to enclose a square shape. An extension part is provided on the outer side of half of each rectangular side. An outer side wall is provided at the edge of each extension part, and an inner side wall is provided at the edge of each rectangular side without an extension part. A card slot is provided on the outer side wall, and a buckle corresponding to the position of the card slot is provided on the outer side of the inner side wall. There are two iron frames, and the two iron frames are respectively an upper iron frame and a lower iron frame that are buckled with each other.
[0030] Since the outer side wall is provided at the edge of the extension part and the inner side wall is provided at the edge of the rectangular side without the extension part, the outer side wall and the inner side wall can be staggered. Then, the two iron frames are buckled with each other, one on top and the other at the bottom. The buckle of the upper iron frame is stuck on the card slot of the lower iron frame, and the buckle of the lower iron frame is stuck on the card slot of the upper iron frame, thereby achieving fixation. In this way, the structures of the upper and lower iron frames are the same, so only one set of molds is needed to produce the upper and lower iron frames, that is, the two iron frames share one set of molds, which is equivalent to doubling the number of iron frame products produced by one set of molds. The cost per iron frame is thus reduced, thereby reducing the cost of the liquid crystal display screen and improving the competitiveness of the product.
[0031] To enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. The present utility model will be described in detail below with reference to the accompanying drawings and embodiments. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation to the present utility model.
[0032] Please refer to Figures 1 to 4, A liquid crystal display screen sharing an iron frame 1 provided by the present utility model, which includes an iron frame 1. The iron frame 1 includes a bottom plate 11. The bottom plate 11 includes four rectangular sides 111. The four rectangular sides 111 are sequentially connected end to end to form a square shape. An extension part 112 is provided on the outer side of half of each rectangular side 111. An outer wall 12 is provided on the edge of each extension part 112. An inner wall 13 is provided on the edge of each rectangular side 111 without an extension part 112. A card slot 121 is provided on the outer wall 12. A buckle 131 corresponding to the position of the card slot 121 is provided on the outer side of the inner wall 13. There are two iron frames 1, and the two iron frames 1 are respectively an upper iron frame and a lower iron frame that are buckled with each other. Since the outer wall 12 is provided on the edge of the extension part 112, and the inner wall 13 is provided on the edge of the rectangular side 111 without an extension part 112, the outer wall 12 and the inner wall 13 can be staggered. Then, the two iron frames 1 are buckled with each other, one on top and the other at the bottom, that is, the upper iron frame is flipped 180° and buckled with the lower iron frame. The buckle 131 of the upper iron frame is stuck on the card slot 121 of the lower iron frame, and the buckle 131 of the lower iron frame is stuck on the card slot 121 of the upper iron frame, so as to achieve fixation. In this way, the structures of the upper and lower two iron frames 1 are the same, so only one set of molds is needed to produce the upper and lower two iron frames 1, that is, the two iron frames 1 share one set of molds, which is equivalent to doubling the number of iron frame 1 products produced by one set of molds. The cost per iron frame 1 is thus reduced, thereby reducing the cost of the liquid crystal display screen and improving the competitiveness of the product.
[0033] Further, a cut 113 is provided in the middle of each rectangular side 111 so that the outer wall 12 and the inner wall 13 can be separated by the cut 113, avoiding the outer wall 12 and the inner wall 13 being pulled together and being difficult to buckle with each other.
[0034] Further, the widths of the cuts 113 of three of the rectangular sides 111 are equal, and the width of the cut 113 of the other rectangular side 111 is greater than the widths of the cuts 113 of the three rectangular sides 111. The cut 113 with a larger width of the cut 113 is used to lead out the FPC8.
[0035] Further, the width of the extension part 112 is greater than or equal to the thickness of the inner wall 13 so that the outer walls 12 and the inner walls 13 of the two iron frames 1 do not interfere with each other and can be easily buckled together.
[0036] Further, each extension part 112 is provided on the left half of each rectangular side 111 so that the iron frame 1 does not interfere with the other iron frame 1 after being flipped 180°.
[0037] Please refer to Figure 5, as a further optimized solution of Embodiment 1, in this embodiment, a TFT module is disposed in the space formed by the buckling of two iron frames 1. The TFT module includes a lower polarizer 2, a lower substrate 3, an upper substrate 4, and an upper polarizer 5 which are sequentially stacked from bottom to top. A double-sided adhesive 6 is disposed on the bottom plate 11 of the lower iron frame, and the lower polarizer 2 is fixedly adhered to the bottom plate 11 of the lower iron frame through the double-sided adhesive 6.
[0038] Further, the lower substrate 3 is longer than the upper substrate 4 and extends outward to form a step, and a driving IC 7 and an FPC 8 are bonded to the upper surface of the lower substrate 3 at the step.
[0039] Further, a shielding paper 9 is disposed on the upper surface of the FPC 8 to avoid problems such as signal interference and static electricity.
[0040] Further, components are disposed on the FPC 8, and an insulating paper is disposed on the lower surface of the shielding paper 9 at the position of the components to avoid short circuit caused by contact between the shielding paper 9 and the components.
