Disclosed is a backlight module structure, comprising a back panel (1), a light guide plate (3) which is arranged in the back panel (1), and at least two backlight sources (5) which are arranged in the back panel (1), wherein the back panel (1) comprises a bottom plate (11) and a plurality of side plates (13) which are perpendicularly connected to the bottom plate (11); and the light guide plate (3) comprises at least two sub-light guide plates (4) which are connected in sequence. A groove (33) is formed at the joint between two adjacent sub-light guide plates (4), an opening of the groove (33) faces the bottom plate (11), the bottom plate (11) is provided with a convex boss (111) corresponding to the groove (33), the two backlight sources (5) are respectively mounted on the convex boss (111) and are accommodated between the groove (33) and the convex boss (111), and the two backlight sources (5) emit light respectively towards the two adjacent sub-light guide plates (4). The backlight module structure can satisfy the requirement of large-scale size of a light guide plate, and can better achieve dynamic dimming at the same time, reducing energy consumption and improving the optical quality. |
