[0017] In order to facilitate the understanding of the present utility model, the present utility model will be described more comprehensively with reference to the relevant drawings. The preferred embodiments of the present utility model are shown in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present utility model more thorough and comprehensive.
[0018] It should be noted that the terms "upper left", "lower left", "upper right", "lower right", "upper edge", "lower edge" and similar expressions used herein are only for the purpose of illustration and do not represent the only embodiment.
[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used in the specification of this utility model are only for the purpose of describing specific embodiments, and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0020] The backlight iron frame designed by this utility model for increasing softness includes an iron frame body 1. Small bumps 11 are provided around the inner side of the iron frame body 1 to fix the backlight. A plurality of first through holes 12 and a plurality of second through holes 13 are provided at the lower edge of the iron frame body 1. The first through holes 12 and the second through holes 13 are arranged in a uniform array. A plurality of third through holes 14 are provided at the lower left and lower right corners of the iron frame body 1.
[0021] The backlight iron frame in this design is applied to the backlight module of the backlight display module, and accommodates components such as the light source, optical film layer, and FPC in the backlight module. In the assembled state, the liquid crystal module of the backlight display module is placed on the backlight module, and the TFT glass of the liquid crystal module contacts the iron frame 1. The small bumps 11 around the iron frame body 1 can not only fix the backlight module, but also reduce the impact of external shocks on the backlight module to a certain extent. The cooperation of the first through holes 12 and the second through holes 13 can improve the softness of the lower edge of the iron frame body 1, and avoid damaging the edge of the backlight glass due to the large hardness of the iron frame body 1 during the assembly or disassembly of the backlight display module, which affects the display. The arrangement of the third through holes 14 can improve the softness in the axial direction of the corners, and prevent the iron frame body 1 from squeezing the corners of the backlight glass during the disassembly process.
[0022] Refer to Figure 1 , Figure 2 , in an embodiment of this utility model, the iron frame body 1 is rectangular. Semi-circular buffer blocks 11 are provided around the inner side of the iron frame body 1 to fix the backlight. The first through holes 12 and the second through holes 13 are provided at the lower edge of the iron frame body 1. The first through holes 12 and the second through holes 13 are arranged in a uniform linear array. The first through holes 12 are small circular through holes, and the second through holes 13 are elliptical long-strip through holes. The major axis of the ellipse of the second through holes 13 is arranged along the left-right direction of the iron frame body. Each elliptical long-strip through hole is provided between two first through holes 12.
[0023] In the assembly and disassembly of this embodiment, the first and second can improve the softness of the lower edge of the iron frame body, making the edge of the lifted lower edge of the iron frame body easier to lift during the assembly and disassembly process, improving the convenience of the assembly and disassembly operations, and not easily squeezing the glass edge on the contacted backlight, effectively preventing the glass from cracking due to extrusion and reducing the defective rate.
[0024] It should be noted that the major axis of the ellipse of the second through-hole is arranged along the left-right direction of the iron frame body, which can improve the softness in the vertical direction along the lower edge of the frame body, contribute to further reducing the cracking of the TFT glass, lowering the cost, and improving the convenience of disassembly operation. The design of this embodiment does not specifically limit the direction setting of the second through-hole.
[0025] In this embodiment, a plurality of third through-holes are provided at the lower left and lower right corners of the iron frame body. The upper left, lower left, upper right, and lower right corners of the iron frame body are arc chamfers, and the four arc chamfers have the same radian. The third through-holes are also small circular through-holes and are evenly arranged along the radian of the arc chamfers at the lower left and lower right corners.
[0026] The layout of the third through-holes and the design of the chamfer structure can improve the softness in the axial direction along the corners, which helps to further prevent the iron frame from squeezing the glass corners during the assembly and disassembly processes.
[0027] In this embodiment, a mobile phone camera avoidance position is also provided in the middle of the upper edge of the iron frame body.
[0028] In summary, the utility model increases the softness by the cooperation of through-holes provided on the frame body, facilitates the assembly and disassembly of the backlight by employees, and avoids damage to the backlight caused by extrusion.
[0029] The above-described embodiments only represent the specific implementation manners of the utility model, and the description is relatively specific and detailed. However, it should not be construed as a limitation of the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
