Abstract:
A backlight unit includes a waveguide layer and a light source component. The waveguide layer includes a light-entering surface located its side surface, a bottom surface located at its bottom, and a light-exiting surface located at its top. A first grating layer is arranged at the bottom surface. A refractive layer is arranged at the light-exiting surface. The light source component is located beside the light-entering surface. The refractive layer includes a refractive lens unit. The refractive lens unit converges the diffracted light dispersed by means of the diffraction caused by the first grating layer when the backlight unit is in operation.

Claim (Index 1):
A backlight unit, comprising a waveguide layer and a light source component, wherein the waveguide layer comprises a light-entering surface located at a side surface of the waveguide layer, a bottom surface located at a bottom of the waveguide layer, and a light-exiting surface located at a top of the waveguide layer,\n wherein a first grating layer is arranged at the bottom surface, a refractive layer is arranged at the light-exiting surface, the light source component is located beside the light-entering surface, the refractive layer comprises a plurality of refractive lens units configured to converge a diffracted light dispersed by means of diffraction caused by the first grating layer when the backlight unit is in operation wherein one of the plurality of refractive lens units closest to the light-entering surface is in a location area where the diffracted light is refracted on the light-exiting surface for the first time, and the distance D between geometric centers of two adjacent refractive lens units is:\n D= 2 L *tan \u03b8 i , \n wherein \u03b8 i  is the incident angle of a light emitted by the light source component at the waveguide layer, and L is the thickness of the waveguide layer.
