Abstract
Description
Technical Field
[0001] The utility model relates to the field of backlight, in particular to the field of backlight flash avoidance. Background Art
[0002] The backlight iron frame is assembled with the backlight through a snap-on structure. After the backlight iron frame is inserted into the backlight, the side wall of the backlight iron frame is assembled with the convex position of the backlight side wall through the groove, so that the backlight iron frame cannot move relative to the backlight in the height direction. However, since the backlight iron frame will leave burrs after the die is punched, especially at the inner snap-on position, many burrs are more than 0.2mm high, and it is difficult to grind the inner burrs smoothly by automatic means. If it is ground smoothly by manual means, the efficiency is low and the probability of not grinding smoothly is also high. The existence of these burrs will easily cause the snaps of the backlight iron frame to be lifted up after assembly, and cannot be effectively buckled, so that the assembled backlight falls off, affecting the assembly quality.

On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.
[0021] It should be noted that when an element is referred to as "snapping" another element, it can overlap or snap onto another element or there can be a central element. The terms "inner side", "outer side", "lower side" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.
[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0023] The utility model discloses an avoidance structure of an LCM backlight and a backlight module comprising the same. The avoidance method is used at the assembly position of the backlight to avoid the burr of an iron frame, thereby preventing the problem of the backlight falling off after assembly due to the burr of the iron frame.
[0024] See also Figure 1 In one embodiment, a LCM backlight avoidance structure is provided, including an LCM backlight 100, a backlight side wall 200 and a backlight iron frame 300, the backlight iron frame 300 includes a panel 301 and a side panel 302, the side panel 302 surrounds the panel 301, the backlight side wall 200 wraps the LCM backlight 100, the side panel 302 is arranged around the outside of the backlight side wall 200, the outside of the backlight side wall 200 is snap-fitted and assembled with the inner side of the side panel 302, and an avoidance area 201 is arranged on the outside of the backlight side wall 200.
[0025] In this way, the fin 3022 is avoided in the assembly position of the backlight iron frame 300 and the backlight side wall 200, so as to achieve the purpose of firm assembly to prevent the backlight from falling, and prevent the fin 3022 from damaging the LCM backlight 100.
[0026] See also Figure 2 and Figure 3 In one embodiment, the backlight side wall 200 is provided with a plurality of buckles 202, and the inner side surface of the side plate 302 is provided with a plurality of hooks 3021, and the hooks 3021 are connected with the buckles 202 one by one, and the buckles 202 are clamped and supported so as not to be disengaged due to looseness, so that the backlight iron frame 300 and the backlight side wall 200 are firmly assembled. In this embodiment, the avoidance area 201 is arranged at the lower side of the buckle 202, and is used to avoid the flash 3022 existing on the inner side surface of the side plate 302 at the assembly position.
[0027] In one embodiment, the avoidance area 201 is a groove with a depth of 0.2 to 0.3 mm, and the height of the groove is greater than the height of the hook 3021, which effectively avoids the flash at the assembly position. In another embodiment, the height of the groove extends from the lower side of the buckle 202 to the bottom of the backlight side wall 200, which can effectively avoid the flash 3022, protect the LCM backlight 100, and simplify the processing.
