Display device and backlight module thereof

Abstract

The invention discloses a display device and a backlight module thereof. The backlight module comprises a first frame body, a second frame body and at least one third fixing part, wherein the first frame body is provided with at least one first fixing part; the second frame body is provided with at least one second fixing part; the second fixing part is provided with a first chute; the second frame body is placed on the first frame body; and the third fixing part is combined with the second fixing part and slides along the first chute until the third fixing part, the second fixing part and the first fixing part are combined so as to clamp and fix the first frame body and the second frame body. In the display device and the backlight module, the first frame body and the second frame body adopt a sliding type positioning fit structure, so the positioning effect is stable, the assembly and disassembly are convenient and rapid, and the assembly quality and assembly efficiency of the backlight module are guaranteed.

Description

technical field [0001] The invention relates to a backlight module, in particular to a backlight module which is convenient for assembling a backplane and a plastic frame and a display device with the backlight module. Background technique [0002] Generally, a liquid crystal display device is composed of a liquid crystal panel and a backlight module. Since the liquid crystal itself does not emit light, the function of the backlight module is to supply sufficient brightness and evenly distributed light source so that it can display images normally. Among them, the backlight module is mainly composed of backlight components such as a backplane, a light source, an optical film group, and a plastic frame. [0003] See figure 1 , Figure 2A and Figure 2B , figure 1 Shown is a schematic diagram of a backlight module in the prior art, Figure 2A shown as figure 1 A partially enlarged schematic diagram of the backplane in, Figure 2B shown as figure 1 The partially enlarg...

AI Technical Summary

Problems solved by technology

[0004] There are many defects in the above-mentioned existing snapping structure of the plastic frame 2 and the back plate 3. For example, during assembly, the operator needs to ensure that each positioning boss 5 has been snapped into the positioning hole 8. If there are one or several If the positioning boss 5 fails to snap into the positioning hole 8 correctly, it is necessary to rework, which will cause a waste of man-hours

Moreover, in order to ensure a stable and firm engagement state between the plastic frame 2 and the back plate 3, the matching dimensions of the positioning boss 5 and the positioning hole 8 are usually designed to be very tight, so that the disassembly operation is extremely time-consuming. laborious, extremely inconvenient

Moreover, during the assembly process of this type of engagement method, due to the interaction between the positioning boss and the positioning hole, it is very easy to jam the plastic frame chips, which affects the quality of the backlight module and the display device.
