Abstract
A backlight module includes a light guide plate and a plurality of light-emitting units. The plurality of light-emitting units emit light toward a light incident surface of the light guide plate. The plurality of light-emitting units are attached to the light incident surface of the light guide plate and arranged along a target direction in manner of spacing between two adjacent light-emitting units. A plurality of light-converging portions are arranged along the target direction in an end portion of the light guide plate where the light incident surface is located, and the plurality of light-converging portions are disposed at locations of the light guide each of which is corresponding to the spacing. The plurality of light-converging portions are configured to converge light incident into the light-converging portions through the light incident surface.
