Abstract:
1. A backlight module, wherein said backlight module comprising: a backplane; a light guide plate, wherein said light guide plate is disposed on one side of said backplane; a heat dissipation element, wherein said heat dissipation element includes a horizontal part and a vertical part interconnected to each other, and said horizontal part is disposed on the other side of said backplane away from said light guide plate, and said vertical part is disposed next to light incident surface of said light guide plate; a light source, wherein said light source is disposed on one side of said vertical part close to said light incident surface; a connector, wherein said connector connects said heat dissipation element to said backplane and allows said heat dissipation element to move relatively to said backplane in the gap direction between said light guide plate and said light source, and said horizontal part is provided with through hole, and said connector comprises the first connecting portion fixed on said backplane, the second connecting portion connected with said first connecting portion and disposed in said through hole and the third connecting portion connected with said second connecting portion and supported on the side of said horizontal part away from said backplane, and said through hole size in said gap direction is greater than the size of said second connecting portion in said gap direction, and said through hole size in said gap direction is greater than said through hole size perpendicular to said gap direction which is parallel to said backplane, and said through hole size perpendicular to said gap direction which is parallel to said backplane is greater than the size of said second connecting portion perpendicular to said gap direction and less than the size of said third connecting portion perpendicular to said gap direction.
