Abstract
A backlight module including an independent light source is provided. The backlight module includes a light generation device, a light transmission device, a light mixing device and a planar light generation device. The light generation device may include one or more light emitting components. The light transmission device may be adopted for receiving and transmitting the light emitted by the light generation device. The light mixing device may be adopted for mixing the light emitted by the light transmission device to generate a mixed linear light. The planar light generation device may comprise a light distributing portion for receiving the mixed linear light to generate a planar light.
