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 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.

摘要： A backlight module (30) includes a light source (42) for emitting light, a light guide plate (50), and a reflective cover (41). The light guide plate includes a light incidence surface (51), a light-emitting surface (53) connecting with the light incidence surface, and a bottom surface (52) opposite to the light-emitting surface. The light source faces the light incidence surface. The reflective cover includes a reflective unit having two reflective surfaces (411, 412) defining a space with a bottom. The light source is accommodated in the bottom of the space. A cross-sectional profile of the reflective surfaces is defined by an equation in a polar coordinate ρ(φ). The equation is: { ∫ π / 2 φ - θ ⁢ ρ ⁡ ( φ ) ⁢ sin ⁡ ( φ - θ ) ⁢ ⅆ ( φ - θ ) = ∫ 0 θ ⁢ 1 cos 2 ⁡ ( θ ) ⁢ ⅆ θ ρ ⁡ ( φ ) = ρ 0 ⁢ { cos ⁡ ( θ / 2 ) / [ cos ⁡ ( φ - θ ) / 2 ] } 2 , wherein, ρ represents a polar axis of the polar coordinate, φ represents a clockwise angle of the polar coordinate, and θ represents an anti-clockwise divergence angle of the light.
