Publication number: 20080170181Abstract: The field of the invention is mainly that of light boxes used for the illumination of display screens using optical valves, notably for liquid crystal matrix displays also known as LCD screens. The light sources used are generally fluorescent tubes powered with a high voltage by devices comprising Royer electronic oscillators. These electronic oscillators do not allow wide dynamic ranges of luminance, which can be necessary for certain applications, to be easily attained. The oscillator according to the invention comprises an electronic device for discharging the stored electrical energy, said discharge device being controlled by an electronic control device using chopping modulation, thus enabling wide dynamic ranges of luminance to be attained.Type: ApplicationFiled: February 27, 2006Publication date: July 17, 2008Inventors: Guy Schou, Frederic Renaud

Publication number: 20080170182Abstract: There is described a process for the production of LCDs, in particular PDLCDs, preferably in a roll-to-roll process, wherein in a first process step a first contact layer (12) and a first electrode layer (14) spaced therefrom is applied to a base carrier (10). A first and a second delimitation layer (18, 20) is then applied to the base carrier (10). Thereafter a functional layer (26) comprising a PDLCD mixture provided in a porous support matrix is applied between the first and second delimitation layers (18 and 20). A protective layer (28) is then applied to the functional layer (26) between the first and second delimitation layers (18 and 20) and finally there is applied to the protective layer (28) a second electrode layer (30) which is contacted with the first contact layer (12).Type: ApplicationFiled: November 1, 2007Publication date: July 17, 2008Inventors: Ulrich Schindler, Steffen Weiss

Publication number: 20080170183Abstract: An electrooptic device simultaneously displays a first image and a second image in different directions. The electrooptic device includes a first polarizer and pixel rows in which first and second pixels are alternately arranged to emit light through the first polarizer. The electrooptic device includes a liquid crystal device that switches between a first alignment state in which a phase difference is not provided to linearly polarized light having a polarization axis parallel or perpendicular to a transmission axis of the first polarizer and a second alignment state with a phase difference of ?/2. The electrooptic device also includes a second polarizer disposed on a display side of the liquid crystal device and having a transmission axis parallel or perpendicular to the transmission axis of the first polarizer. The first and second pixels display different images depending on the alignment state of the liquid crystal device.Type: ApplicationFiled: January 15, 2008Publication date: July 17, 2008Applicant: SEIKO EPSON CORPORATIONInventor: Nobuo SUGIYAMA
