摘要： A light guide device (52) includes a light guide substrate (520) and a sub-wavelength grating (527). The light guide substrate has a light input surface (521), a light output surface (522) adjacent to the light input surface (521), a bottom surface (523) opposite to the light output surface (522). In the light guide plate, stress-induced birefringence is introduced to achieve the polarization state conversion. The SWG 527 located on the light output surface includes a top layer (525) and a bottom layer (526). The SWG 527 is configured to work as a reflective polarizing beam splitter, consistent with the principle of rigorous coupled-wave theory.

摘要： A light guide plate includes an incident surface, an emission surface, and a bottom surface. The emission surface intersects with the incident surface and is substantially perpendicular to the incident surface. The bottom surface intersects with the incident surface and is opposite to the emission surface. The light guide plate is birefringent and has internal stresses/strains therein, causing the light guide plate to exhibit a light-polarizing phase delay. An angle between a direction of one of the main stresses/strains and the light incident surface is bigger than 0 degree and smaller than 90 degrees. A plurality of sub-wavelength gratings can be further formed on the emission surface of the light guide plate. A backlight module, adopting the above-mentioned light guide plate, further includes a corresponding light source positioned beside the incident surface of the light guide plate.

摘要： A backlight module includes a light guide plate, a light source, and a reflector. The light guide plate includes an incident surface and a corner adjacent the incident surface. The light source is disposed adjacent the incident surface and the corner of the light guide plate. The light source has an emitting surface. The reflector is disposed substantially facing the incident surface. The reflector has a curved reflective surface facing the emitting surface, the surface being shaped and positioned for uniformly reflecting light beams emitted from the light source into the light guide plate through the incident surface. An angle of inclination of the emitting surface with respect to the incident surface is chosen to be in the range from above about 0 to about 180 degrees. The backlight module can effectively eliminate shadow formation adjacent the incident surface of the light guide plate.

A second base angle of the cross-section is in the range from 15° to 50°. A distribution density of the V-shaped projections progressively increases along a direction away from the incident surface. A size of the V-shaped projections progressively increases along a direction away from the incident surface.
