摘要： A light guide plate (10) includes a transparent plate (20), and a plurality of diffusing protrusions (30). The transparent plate includes an emitting surface (21), and a bottom surface (23) opposite to the emitting surface. The diffusing protrusions are distributed evenly on the emitting surface of the transparent plate, and are integrated with the transparent plate. The diffusing protrusions are hemispherical or sub-hemispherical, and a diameter of each diffusing protrusion is in the range from 10 μm˜50 μm. The light guide plate provides high emitting brightness and uniformity. The diffusing protrusions can diffuse light beams emitting from the emitting surface of the transparent plate, in order to achieve a plane light source having even brightness. The present Invention also discloses a method for fabricating the light guide plate.

摘要： A backlight system (100) in accordance with the present invention includes a plurality of light sources (110) for emitting light beams and a light guide plate (120) for receiving the light beams emitted by the light sources. The light guide plate includes a light input surface (121) and a light output surface (122) joining the light input surface. The light input surface has a plurality of recesses (124) therein. The recesses have cylindrical surfaces, each having a specific curvature, and the light beams emitted by the light sources pass through the cylindrical surfaces orthogonally. Since nearly all of the light beams enter into the light guide plate with few being reflected at the light input surface, the backlight system is highly efficient in light utilization.

摘要： A method for fabricating a light guide plate (80) includes: providing a first substrate (30), and coating a photo-resist layer (600) thereon; exposing and developing the photo-resist layer to form a photo-resist pattern (640); etching the first substrate; removing the photo-resist pattern; coating a metal film (520) on the first substrate; electroforming a metal layer (540) on the metal film; removing the first substrate to thereby obtain a molding core (500); providing a second substrate (70), and hot-pressing the second substrate in a hot-press die (40) using the molding core; and removing the second substrate to thereby obtain the light guide plate. The second substrate is heated until it is plastic, so that it can be easily pressed to form a predetermined shape. During the whole process, the second substrate is never in liquid form, so that the “reflux” problem of the prior art is effectively eliminated.

摘要： A backlight assembly (100) for providing bright and uniform light beams to illuminate an LCD panel includes a light source (120), a reflector (130), and a diffusion sheet (150). The light source is positioned between the reflector and the diffusion sheet, and the diffusion sheet has at least one diffraction grating (151) formed on a surface thereof facing the light source. The backlight assembly has a simple configuration for providing bright and uniform light beams to illuminate an LCD panel. Furthermore, the diffusion sheet is made of a transparent piezoelectric material. When an electric field is applied on the diffusion sheet by a controlling circuit, the diffusion sheet is induced to deform. Thus the distribution of light intensity can be modulated according to need.

摘要： A light-emitting diode (LED) (10) includes a chip body (103), an encapsulation can (105) surrounding the chip body, and a base (106) supporting the encapsulation can and the chip body thereon. Numerous fluorescent particles (1050) are provided in the encapsulation can. With the fluorescent particles, light beams from the chip body are diffused and attain wider irradiation angles. A backlight system (900) includes a light guide plate (20), and a number of the above-described LEDs disposed adjacent to the light guide plate. Light beams having wide irradiation angles are emitted from the LEDs and enter the light guide plate. This enables a light emitting surface of the light guide plate to have highly uniform brightness.

摘要： A tunable optical wavelength demultiplexer (10) has a plurality of demultiplexer units (113, 114, 115, 116) formed on a planar waveguide (111). Every demultiplexer unit comprises a plurality of input waveguide channels, a plurality of output waveguide channels, and a Bragg grating, said each input waveguide channel coupling with the Bragg grating at a different angle, and each output waveguide channel being a mirror image of a corresponding input waveguide channel. Bragg gratings of demultiplexer units are parallel each other. Corresponding input waveguide channels are parallel to each other. An adjustable mechanism (100) adjusts an input port (25) and output ports (271, 272, 273, 274) to couple with a desired input waveguide channel and corresponding output waveguide channels.
