  • Publication number: 20080084709
    Abstract: A light guide plate, for use with a back-light module for seasonal scanning in dividing zones, includes a light-pervious substrate having a plurality of dividing blocks formed thereon, an optical grating structure disposed on light incident surface of each of the dividing blocks for allowing light to enter, and a light diffusion structure disposed on an optical surface of each of the dividing blocks for diffusing the light. As the light-pervious substrate is adapted for seasonal scanning in different zones, the provision of the optical grating structure can shorten the light mixing distance while the light diffusion structure can evenly emit and spread the light throughout the light guide plate to solve the drawbacks of the prior techniques. Further, a back-light module having the light guide plate is provided.

  • Patent number: 7251412
    Abstract: Direct backlight modules using diffraction optical elements are provided. A direct backlight module includes a light source and a diffraction optical element, wherein the diffraction optical element is disposed above the light source. By properly arranging the phase function, the diffraction optical element can substantially modulate the wavefront of the light emitted from the light source and control light distribution as well as light direction.

  • Patent number: 6621959
    Abstract: The invention provides a planar waveguide diffractive 1×N beam splitter/coupler. It utilizes an integrated circuit fabrication process to fabricate an integrated optic. A Fourier transform diffractive optical element (DOE) is formed on one end of a planar waveguide (planar lightwave circuit; PLC). Thus, an incident beam coming from one end of the planar waveguide can be diffracted into a plurality of output beams. On the other hand, a plurality of incident beams coming from one end of the planar waveguide can be coupled into one output beam. The beam splitter/coupler is easy to fabricate, small in size and more flexible for applications.
