  • Publication number: 20130207908
    Abstract: A cholesteric liquid crystal touch display panel includes an upper substrate, a lower substrate, a cholesteric liquid crystal display layer, and a color sensor array. The cholesteric liquid crystal display layer is disposed between the upper substrate and the lower substrate. The cholesteric liquid crystal display layer includes a plurality of liquid crystal display units, which are used to reflect light within a wavelength range and allow light beyond the wavelength range to pass through. The color sensor array is disposed between the cholesteric liquid crystal display layer and the lower substrate. The color sensor array includes a plurality of color sensors. Each of the color sensors is disposed correspondingly to at least one liquid crystal display unit. Each of the color sensors is used to sense variations of light from the corresponding liquid crystal display unit.

  • Patent number: 8410531
    Abstract: A thin film transistor having Schottky barrier includes a substrate, a first gate conductive layer formed on the substrate, a first semiconductor layer having a first conductive type formed on the first gate conductive layer, a source conductive layer and a drain conductive layer electrically isolated from each other and positioned on the first semiconductor layer, a second semiconductor layer having a second conductive type formed on the source conductive layer and the drain conductive layer, and a second gate conductive layer formed on the second semiconductor layer. The first conductive type is complementary to the second conductive type.
