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

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
