Abstract
A backlight source includes: an LED light source for emitting a visible light, a light guide plate and an infrared quantum point, wherein the LED light source is arranged on a light incidence side of the light guide plate and the infrared quantum point is arranged on at least one face of the light guide plate. And the infrared quantum point is excited by a part of the visible light emitted from the LED light source to emit an infrared light. The other part of visible light emitted from the LED light source exits uniformly a light exit face of the light guide plate along with the infrared light. The infrared quantum point is arranged on at least one face of the light guide plate other than the light incidence face and the light exit face.
