| description | The utility model discloses a directional backlight module and a directional backlight three-dimensional display device, and the directional backlight module comprises a blue light laser which is configured to emit blue light; the light beam scanning mechanism is configured to form a blue light dot matrix light source; the optical film group is configured to modulate the blue light dot matrix light source to form a line light source which emits light uniformly; and a first lens array configured to form a directional backlight source; wherein the blue laser, the light beam scanning mechanism, the optical film group and the first lens array are sequentially arranged in the direction of a laser light source propagation path. According to the technical scheme, the color rendering property of backlight can be improved, the display color gamut range is enlarged, laser speckle interference can be effectively eliminated, and the uniformity of the laser speckle interference is improved.
