Patent ID: 8504113

Claim:
A mobile terminal, comprising: a display panel configured for displaying information, the display panel having a first surface and a second surface opposite the first surface, the first surface facing an exterior of the mobile terminal and the second surface facing an interior of the mobile terminal; a plurality of light source units positioned in the interior of the mobile terminal under the display panel, the plurality of light source units comprising a plurality of blue light emitting diodes (LEDs) and a plurality of green LEDs, and each of the plurality of light source units are spaced apart from other of the plurality of light source units; a fluorescent unit positioned on a light emission surface of at least a portion of the plurality of light source units, the fluorescent unit comprising a plurality of red quantum dots; and a light guide plate positioned in the interior of the mobile terminal under the display panel, wherein a portion of blue light emitted from the blue LEDs and a portion of green light emitted from the green LEDs are transformed into red light by colliding with the plurality of red quantum dots and the red light is output via a light output surface of the fluorescent unit, wherein another portion of the blue light and another portion of the green light pass directly through the fluorescent unit without colliding with the plurality of red quantum dots, and the another portion of the blue light and the another portion of the green light are output via the light output surface of the fluorescent unit, and wherein the red light, the green light and the blue light output via the light output surface of the fluorescent unit are synthesized into a white light in the light guide plate.
