  • Patent number: 9146222
    Abstract: The system for detecting volatile organic compounds (VOCs) of this present invention comprises a detecting material made by blending a nano-material and a conductive polymer. The system for detecting VOCs presents the property of high sensitivity, high sensing accuracy, quick response, and real-time VOC detecting, and is demonstrated in the present work for commercialization usage. The system for detecting VOCs can be easily operated to detect VOC without electronic detecting method, and hence this invention can reduce a lot of operation energy and procedure. Furthermore, when adding inorganic nanoparticles, the area of VOC exposure of this invention is increased and the molecular morphology variation of the detecting material is enhanced, and hence the detecting activity of the system for detecting VOCs is improved.

  • Publication number: 20130293793
    Abstract: A display apparatus having a backlight module, a modulatable parallax barrier module, a polarizer film and a display panel is provided. The backlight module provides a linear polarized light having a first polarization direction. The modulatable parallax barrier module has an alignment state and a transparent state, and has a first alignment film with a first alignment direction on the light-emitting side. The linear polarized light passing through the modulatable parallax barrier module in the transparent state is kept in the first polarization direction, and passing through the modulatable parallax barrier module in the alignment state is transformed to a second polarization direction. The polarizer film has a transmission axis inclined toward either the first polarization direction or the second polarization direction. The modulatable parallax barrier module selects one of the alignment state and the transparent state according to an image information provided by the display panel.
