Embodiment 1

[0056] This embodiment provides a liquid crystal display device. The overall structural diagram of the liquid crystal display device in this embodiment is shown in image 3 As shown, the partial enlarged structural cross-sectional view of the liquid crystal display device in the M region along the A direction is shown as Figure 4 shown. The liquid crystal display device mentioned in this embodiment includes: a backlight module 200 and a panel 205 , wherein the backlight module 200 includes: a front frame 201 , a back plate 202 , a plastic frame 203 and a light guide plate 204 .

[0057] Wherein, the back plate 202 includes a bottom plate 2022 and a vertical plate 2021 surrounding the edge of the bottom plate 2022, and the bottom plate 2022 is used to place the light guide plate 204, and a sliding button is protruded from the outer surface of the vertical plate 2021; the front frame 201 includes a side wall 2011, the inner side of the side wall 2011 is provided with a slidewa...

Embodiment 2

[0084] This embodiment provides a backlight module. The backlight module is the backlight module mentioned in Embodiment 1 in the liquid crystal display device. The specific structural diagram of the backlight module 200 is as follows Figure 11 As shown, the backlight module 200 includes: a front frame 201 , a back plate 202 , a plastic frame 203 and a light guide plate 204 .

[0085] The purpose of this embodiment is to provide a new fixing method of the front frame 201 and the back plate 202 in the backlight module, and change the screw fixing method of the front frame and the back plate in the prior art to a fixing method of slide rails, This fixing method can save the width distance occupied by the fixing screws, and the sliding buckle fixing design of the slideway is a screwless design, which can make full use of the existing space in the height direction of the side wall of the front frame and the back panel vertical plate, saving The structure of the locking screws on ...

Embodiment 3

[0087] Different from the method of fixing the backplane 202 and the front frame 201 in the first embodiment, which is a slideway slide button connection, the purpose of this embodiment is to provide another way of fixing the backplane and the front frame.

[0088] The partial structural diagram of the backplane in this embodiment is as follows Figure 12 As shown, the back plate 301 includes a vertical plate 3012 and a bottom plate 3011, the vertical plate 3012 is set perpendicular to the bottom plate 3011, and a first column 3013 is set on the outer surface of the vertical plate 3012, and the number of the first column 3013 can be one or more , open in pairs on the outer surface of the vertical plate 3012, set up the second column 3014 on the top surface of the first column 3013, the cross-sectional area of ​​the second column 3014 is greater than the cross-sectional area of ​​the first column 3013, the second column 3014 The top surface is chamfered so that the outer surfac...

Abstract

The invention provides a backlight module and a liquid crystal display device. The backlight module comprises a back plate and a front frame. The back plate comprises a vertical plate and a bottom plate arranged on the surface of the vertical plate in the horizontal direction. A sliding fastener is arranged on the outer surface of the vertical plate in an outward protruding mode. The front frame comprises a side wall and a support arm arranged on the side wall surface in the horizontal direction. A sliding way parallel to the length direction of the front frame is arranged on the inner side of the side wall. The sliding fastener can slide in the sliding way in the length direction, and when the sliding fastener slides, the sliding fastener is limited in the sliding way so as to be prevented from disengaging from the direction perpendicular to the length direction of the sliding way. The liquid crystal display device comprises a panel and the backlight module. Screw-free fixation is achieved through a structure of the sliding way and the sliding fastener, the width distance occupied by the back plate at the fixation end can be reduced, the allowed distance in the width direction of an existing panel resource is met, it is not required to increase side width, and the side narrowing of the liquid crystal display device is achieved easily.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a liquid crystal display device. Background technique [0002] The important components of the liquid crystal display device are the panel and the backlight module. The backlight module mainly includes a front frame, a back plate, a light guide plate, a plastic frame, and a diaphragm. [0003] When designing an ultra-thin liquid crystal display device, the structure of the liquid crystal display device is designed as follows: figure 1 As shown, the liquid crystal display device includes a front frame 101, a back plate 102, a plastic frame 103, a light guide plate 104, a panel 105, a front frame lower arm 1011, a front frame upper arm 1012, and a screw flange 1021. figure 1 It can be seen from the figure that the back plate 102 and the front frame 101 are fixed by locking screws on the back, and the specific fixing method is as follows: threaded holes and ...
