A backlight module includes a light guide plate (52), a light source (51), a reflecting sheet (53), a diffusion sheet (54), and a reflective polarizing beam splitter (57). The light guide plate includes a light input surface (521), a light output surface (522) adjacent to the light input surface, a reflecting surface (523) opposite the light output surface, and a number of microstructures (524) located on the reflecting surface. In the light guide plate, stress-induced birefringence is introduced to achieve a polarization state conversion, thereby facilitating efficient use of the light generated by the light source.

An exemplary refractive-index sensor includes a photonic crystal microcavity structure, a light source, and a detector. The photonic crystal microcavity structure includes a photonic crystal layer having first holes and a second hole. The first holes are arranged in a pattern of staggered parallel rows. The second hole is located at an approximate center point of the middle row of the pattern rather than a first hole. A diameter of the second hole is less than that of each of the first holes. Some of the first holes disposed at each of opposite ends of a diagonal row having the second hole are omitted to define an input waveguide and an output waveguide. The light source is adjacent to the input waveguide. The detector is adjacent to the output waveguide.

A light guide device includes a main body and a plurality of parallel elongate first V-shaped microstructures. The main body has an incident surface; an emitting surface adjoining the incident surface; and a reflecting surface opposite to the emitting surface. The first V-shaped microstructures are provided on the reflecting surface. Each of the first V-shaped microstructures has a triangular cross-section having a first base angle nearest the incident surface, a second base angle furthest from the incident surface and a vertex angle. A pitch between adjacent microstructures is configured to be substantially constant. A size of each of the first V-shaped microstructures is defined by the equation is y=9.2637×10−6x2−0.0003x+0.0232, wherein x is a distance from a given first V-shaped microstructures to the incident surface (in units of micrometers), and wherein y is a base width of the given first V-shaped microstructures (in units of micrometers).

A light guiding plate (120) includes a light incident surface (121), a light emitting surface (122) adjacent to the light incident surface, and a bottom surface (123) opposite to the light emitting surface. The light incident surface includes at least one row of first grooves (1211) and at least one row of second grooves (1212). The first grooves is configured for increasing a range of incident angles in which light beams enter the light guiding plate via the light incident surface and thereby improving a brightness of the light guiding plate, and the second grooves is configured for complementing the functions of the first grooves thereby improving a uniformity of light output by the light guiding 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.
