Patent number: 6606138Abstract: A reflecting film is formed on one substrate, and ¼ wavelength layer is arranged on this reflecting film. A liquid crystal layer comprises liquid crystal molecule, a polymer and dichroic dye, the polymer particles being dispersed in liquid crystal molecules. Using this configuration, a liquid crystal apparatus free from parallax is available. Because the dichroic dye is mixed in the liquid crystal layer, a light entering the liquid crystal layer upon non-application of voltage is absorbed by the dichroic dye, thus giving a light absorbing state. Upon application of voltage, there is available a light scattering state.Type: GrantFiled: January 22, 1998Date of Patent: August 12, 2003Assignee: Seiko Epson CorporationInventor: Tomio Sonehara

Patent number: 6388697Abstract: An image forming device for forming optically inputted two-dimensional images. A light valve, including a bistable electrooptic medium and a photoconductive material, acts as an image recording device which records an image inputted from an image inputting device. When the light valve is irradiated by the light from the image inputting device, the electrooptic medium makes a state transition by photoelectric converting action of the photoconductive material. The state of the electrooptic medium is dependent on the threshold voltage across the light valve and on the threshold intensity of the input light. The recorded image can be outputted to film or any type of visual display apparatus. The image inputting device can be a modulated scanned light beam, as from a laser.Type: GrantFiled: August 23, 1994Date of Patent: May 14, 2002Assignee: Seiko Epson CorporationInventors: Tomio Sonehara, Hidekazu Kobayashi
