Backlight module and display device

Abstract

The invention discloses a backlight module and a display device. The backlight module comprises a light source module, a framework, a fixing part and an elastic element. The light source module comprises a circuit board provided with a first fixing hole and an LED; the side wall of the framework is provided with a second fixing hole; the fixing part comprises a first part, a second part and a third part, and the first part is in a thread structure; and the elastic element is arranged between the side wall and the circuit board. The first part penetrates through the second fixing hole to be locked and fixed with the first fixing hole, and the second part is movably positioned in the second fixing hole. When light source module is pressed to compress the elastic element, the light source module moves towards a first direction facing the side wall, and the second part moves towards the first direction along the second fixing hole; and when the elastic element recovers, the light source module moves towards a second direction far away from the side wall, and the second part moves towards the second direction along the second fixing hole. The elastic element of the light source module ensures that the light source module can move relative to the framework and can prevent the LED from being damaged by pressing.

Description

technical field [0001] The invention relates to a backlight module and a display device, in particular to a backlight module and a display device with a movable light source module. Background technique [0002] See Figure 1A-Figure 1C , Figure 1A Shown is a schematic diagram of a backlight module in the prior art, Figure 1B shown as Figure 1A A schematic diagram of the fixture in, Figure 1C shown along Figure 1A The schematic cross-section of the line AA' in the center. In the prior art, the backlight module 1 includes a light source module, a heat dissipation mechanism 3 , at least one fixing piece 4 , a backplane 9 and a light guide plate 2 . The light source module includes a circuit board 5 and a plurality of light-emitting diodes 6 electrically arranged on the circuit board 5. The circuit board 5 has a first fixing hole; the side wall of the heat dissipation mechanism 3 has a second fixing hole; the fixing member 4 is are screws; the light incident surface ...

Problems solved by technology

However, in this assembly method, the light source module is inactive, and is limited between the heat dissipation mechanism 3 and the light guide plate 2. When the light guide plate 2 absorbs moisture and expands due to heat, the light guide plate 2 expands and pushes against the light-emitting diodes 6, which will Cause the light-emitting diode 6 to burn and fail to light up
