Abstract
Backlight module and display device are provided. The backlight module includes an accommodation frame including a base and an extending part, a first light guide plate, a second light guide plate; a first reflector, a first light source, and a second light source. The first light guide plate and the second light guide plate are disposed sequentially along a direction perpendicular to a plane of the base in an accommodation space formed by the base and the extending part, and are controlled independently. The first light source has a wavelength λof 780 nm<λ≤1310 nm, and the second light source has a wavelength λof 380 nm≤λ≤780 nm. A reflectivity of the first reflector on light emitted by the second light source is larger than a reflectivity of the first reflector on light emitted by the first light source.
