摘要： To control chroma and brightness in a backlight module, a plurality of reference values of a plurality of monochromatic light beams are provided, and a brightness reference value is provided for the light formed of the monochromatic light beams. Then, a plurality of first light signals of the monochromatic light beams, and a second light signal of the light formed of the monochromatic light beams are sensed and compared with the reference values and the brightness reference value, respectively. Finally, the monochromatic light beams outputted by the plurality of LEDs is calibrated according to a comparison result of the plurality of first light signals with the plurality of reference values and a comparison result of the second light signal with the brightness reference value.

摘要： A light source device includes a first light-emitting element providing illumination beams, a light guide plate (LGP) divided into light-transmissive regions, an optical thin film, and microstructures. The LGP has a first surface, a second surface opposite to the first surface, and a first light-incident surface connecting the first and second surfaces. The first light-emitting element is beside the first light-incident surface. The illumination beams are capable of entering the LGP through the first light-incident surface. The optical thin film is on the second surface of the LGP. The optical thin film has different thicknesses corresponding to at least two of the light-transmissive regions. The microstructures are on the optical thin film. When the illumination beams pass through the light-transmissive regions corresponding to the different thicknesses of the optical thin film and leave the LGP through the first surface, the illumination beams are converted into color beams with different wavelengths.

摘要： A light guide plate includes a plate-shaped transparent body and a plurality of stripe-shaped planar structures. The plate-shaped transparent body is bent to form a top portion, a bottom portion, and a curved portion connected between the top portion and the bottom portion, and the top portion and the bottom portion are substantially parallel to each other and define a gap therebetween. The stripe-shaped planar structures are connected with each other on an outer surface of the curved portion.
