  • Patent number: 6744481
    Abstract: A liquid crystal display panel (LCD) having display capability on both sides. The LCD comprises a liquid crystal module, a first front polarizer, a first rear polarizer, a first reflector, a second front polarizer, a second rear polarizer, and a second reflector. By replacing a portion of the original front polarizer with the first rear polarizer and the first reflector, and replacing a portion of the original rear polarizer and the original reflector with the first front polarizer, the LCD having display capability on both sides can be attained.

  • Patent number: 6738111
    Abstract: An arm portable information apparatus has a case and a film liquid crystal device disposed in the case and having a pair of opposite side edge portions. A pair of support members are connected to the case and support the film liquid crystal device. Each of the support members has at least one groove receiving a respective one of the side edge portion of the film liquid crystal device so that the film liquid crystal device does not contact any part of the arm portable information apparatus except for the contact between the support members and the side edge portions of the film liquid crystal device.

  • Patent number: 6031586
    Abstract: Printing apparatus for radiation thermal transfer of colorant from a donor to a receiver, including a flash tube for emitting high intensity radiation; a polarizer for receiving high intensity radiation from the flash tube and polarizing such radiation; and liquid crystal cells disposed to receive polarized radiation from the polarizer. Electrodes modulate the liquid crystal cells so that they change the polarization of the radiation passing through them. A second polarizer receives radiation from the liquid crystal cells and is arranged to pass different intensities of radiation depending on their polarization. The colorant donor and the receiver are positioned in colorant transfer relationship with the second polarizer at a colorant transfer position so that radiation which passes through the second polarizer illuminates the colorant donor so that colorant is transferred to the receiver.
