Patents by Inventor Yuusaku Saitou

Yuusaku Saitou has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7742143
    Abstract: A protective measure against rainfalls or ultraviolet rays is applied to planar display devices which comprise a large-sized display apparatus thus allowing display modules which include display devices to be used outdoors and, at the same time, the structure of a frame is simplified thus realizing the reduction of weight, thickness and a manufacturing cost of the large-sized display apparatus. In a large-sized display apparatus arranging a plurality of planar display devices, as the planar display device, a display device which comprises a display device body which includes a display region in the inside thereof and has a peripheral portion of the display region sealed, and a protective glass which is fixedly mounted on a front surface of the display device body using an adhesive material is used.

  • Publication number: 20070103386
    Abstract: The present invention provides a display device which includes at least one module mounting frame which is mounted on a display device mounting structure, a plurality of display modules which are detachably mounted on the module mounting frame and constitute a display screen, a signal cable which has a wiring route in the inside of the module mounting frame and is detachably connected to the display modules and supplies image signals to the display modules, and a power source cable which has a wiring route in the inside of the module mounting frame and is detachably connected to the display modules thus supplying electric power to the display modules. Due to such a constitution, it is possible to realize the reduction of weight and the lowering of the manufacturing cost.

  • Publication number: 20060262058
    Abstract: A high-contrast halftone image is achieved by combining drives based on right- and left-hand characteristics of cholesteric liquid crystals. A first process displays a binary image of white and black based on the right-hand characteristics of voltage-reflectance characteristics. This achieves good black with a low reflectance. A subsequent second process displays an image based on driving voltages in the left-hand characteristics. The voltages in the left-hand characteristics produce good halftone displays. At this time, the liquid crystal state makes a transition in the direction of reducing the reflectance from planar to focal conic alignment. This allows high-contrast halftone displays while maintaining a good black level obtained in the first process.
