Backplate and backlight module comprising the same

A backplate for use in a backlight module, comprising:

• a baseplate for supporting a light guide plate;
• four side plates, being disposed perpendicular to the baseplate respectively to form a receiving space for receiving the light guide plate;
• and
• at least one bridging structure, extending inwards from an inner surface of the side plates by a certain distance to support and locate at least one light source and the light guide plate;
• wherein the at least one bridging structure is a polyhedral 3D structure protruding outwards, and an upper surface of the at least one bridging structure adjoining the at least one light source and the light guide plate is a planar surface;
• wherein the baseplate is at a higher level than a lower edge of each of the side plates, and an upper surface of the baseplate is within a same horizontal plane as the upper surface of the at least one bridging structure.

A backlight module, comprising:

• a light guide plate;
• at least one light source for providing light;
• and
• a backplate, comprising:
• a baseplate for supporting the light guide plate;
• four side plates, being disposed perpendicular to the baseplate respectively to form a receiving space for receiving the light guide plate;
• and
• at least one bridging structure, extending inwards from an inner surface of the side plates by a certain distance to support and locate the at least one light source and the light guide plate;
• wherein the light guide plate comprises a plurality of light incident surfaces, the backlight module comprises a plurality of light sources, and the backplate comprises a plurality of bridging structures each of which is disposed on the side plates that directly face the light incident surfaces of the light guide plate to support the light sources respectively.
