Through setting up two knot holes 101, buckle main part 222a corresponds and is equipped with two to block in two knot holes 101 respectively, then further improved the steadiness that joint portion 222 is connected with backplate 100. In addition, the two buckle main bodies 222a are oppositely arranged, and the two ends of the reinforcing section 222b are respectively connected with the two buckle main bodies 222a, so that the connection strength of the buckle main bodies 222a is further enhanced, and the service life of the bracket 200 is prolonged.
Referring to fig. 1 to 3, the cross-sectional shape of the buckle main body 222a is T-shaped, such that the area of the side of the buckle main body 222a away from the reinforcing section 222b is larger than the area of the cross-section of the buckle hole 101 (the cross-section is parallel to the side of the buckle main body 222a away from the reinforcing section 222 b), so that after the buckle main body 222a is connected with the buckle hole 101, the buckle main body 222a can be limited by the side plate of the back plate 100, and the buckle main body 222a is prevented from being separated from the side plate.
Further, the bracket 200 is a rubber bracket or a silicone bracket.
By setting the support 200 as a rubber support or a silicone support, the support 200 is easily elastically deformed under the action of an external force. For example, when the mounting opening 201a of the groove 201 of the bracket 200 is smaller or the inner dimension of the groove 201 is slightly smaller than the outer dimension of the ic board 300, a user may apply a pressure to the wall of the groove 201 in a direction away from the groove 201, so that the wall of the groove 201 is deformed to enlarge the dimensions of the mounting opening 201a and the groove 201, thereby facilitating the mounting of the ic board 300; after the integrated circuit board 300 is installed in the groove 201, the user can remove the pressure on the wall of the groove 201 of the bracket 200, and then the wall of the groove 201 can be automatically restored to the original position, thereby realizing a better clamping effect on the integrated circuit board 300 and ensuring that the integrated circuit board 300 has a firmer installation effect when installed in the groove 201.
Further, the bracket 200 is injection molded to the backplate 100.
By injection molding the bracket 200 on the backboard 100, the connecting strength between the bracket 200 and the backboard 100 is increased, and the bracket 200 is prevented from being separated from the backboard 100. In addition, the mounting process of the bracket 200 and the backboard 100 is omitted, and the mounting process is further simplified.
Of course, in other embodiments, the bracket 200 may also be detachably connected to the backboard 100, so that when the backboard 100 or the bracket 200 is damaged, a user may only replace the damaged component, thereby saving the replacement cost.
The present application further provides a display device, as shown in fig. 1, fig. 3, or fig. 5, where the display device includes a display panel 600 and a backlight module, and the specific structure of the backlight module refers to the foregoing embodiments, and since the display device adopts all technical solutions of all the foregoing embodiments, the display device at least has all beneficial effects brought by the technical solutions of the foregoing embodiments, and details are not repeated here. The display panel 600 has a light incident surface 610 and a light emitting surface 620 opposite to each other, and the backlight module is disposed on a side of the light incident surface 610 departing from the light emitting surface 620.
By disposing the backlight module on the side of the light incident surface 610 of the display panel 600 away from the light emitting surface 620, the backlight module can provide light for the display panel 600, so that the light emitting surface 620 of the display panel 600 can display a picture for a user to watch.
The above description is only a preferred embodiment of the present application, and not intended to limit the scope of the present application, and all modifications and equivalents of the technical solutions that can be directly or indirectly applied to other related fields without departing from the spirit of the present application are intended to be included in the scope of the present application.
