  • Patent number: 8410707
    Abstract: The present disclosure relates to a duty cycle adjusting circuit of a lighting system and method thereof for sensing light of a first color and a second color emitted by a light emitting device of the first color and a light emitting device of the second color to generate corresponding intensity values. Then a first pulse width correcting value and a second pulse width correcting value can be calculated for adjusting a first duty cycle and a second duty cycle of a driving current to adjust the illuminating intensity of the light emitting devices of the first and the second colors. Through these adjusting steps, the light of the first and the second colors is within a predetermined range of color temperature. Therefore, light source for stable light in color temperature is provided.

  • Patent number: 7997748
    Abstract: A stereoscopic display device includes a substrate, a plurality of odd-line light source units, a plurality of even-line light source units, a lens array, and a circuit. The odd-line light source units and the even-line light source units are provided at a first side of the substrate and spaced from each other. Each of the odd-line light source units and the even-line light source units include a plurality of light source pixel units. The lens array is arranged on the substrate at the first side thereof and includes a plurality of cylindrical stripe-like lenses, the cylindrical stripe-like lenses extending substantially parallel to each other. The circuit is configured for alternately outputting a first time sequence display signal to the odd-line light source units and a second time sequence display signal to the even-line light source units.
