A double-layered backlight module includes a supporting plate having a supporting surface and a plurality of through holes formed thereon. A plurality of light sources is disposed on the supporting surface. A first optical modulation film is disposed at one side of the supporting plate where the plurality of light sources is located, and a first interlayer is formed between the first optical modulation film and the supporting surface. The first optical modulation film includes a first reflective surface formed at one side of the first optical modulation film facing the plurality of light sources and a plurality of first light exiting holes penetrating the first optical modulation film. A first diffusing plate is disposed at one side of the first optical modulation film opposite to the supporting plate. A second diffusing plate is disposed at one side of the supporting plate opposite to the supporting surface.

Double-layered backlight module

A fixing structure and a backlight module using the same are provided. The fixing structure is used for fixing a circuit board. The circuit board with several openings has an upper surface and a lower surface. The fixing structure includes a back plate and several hooks. The back plate has a contact surface. These hooks are disposed on the contact surface. The hooks go through the openings so that the contact surface contacts the lower surface. The hooks move toward the walls of the openings and press against the upper surface so as to fix the circuit board onto the back plate.

A supporting structure is applied to a backlight module including several optical sheets. The supporting structure includes a fixing component and a supporting component. The fixing component has a through-hole and an opening connected to each other. The supporting component includes a supporting pin, a block, a plate and a protrusion. The supporting pin has a top end for supporting the optical sheets and a bottom end at which the block is disposed. The plate is disposed on the supporting pin. The protrusion is disposed on the plate and faces the bottom end. After the block goes through the through-hole and rotates an angle, the plate and the block respectively press against upper and lower surfaces of the fixing component for clamping the fixing component. The protrusion is engaged in the opening for positioning the supporting component, so that the supporting component is fixed onto the fixing component.

A plurality of reflecting structures are provided at the corner portions of a backlight module, so that the dark areas occurring at the corner portions or edges of the backlight module are prevented from forming, thereby uniforming the luminance performed by the display.
