  • Patent number: 8593054
    Abstract: An image display element includes: a front panel; a back panel opposite thereto; a plurality of pixels arranged between both the panels; and plural electrodes for controlling the pixels. The panels are bonded with the pixels and the electrodes interposed therebetween, and the electrodes are connected to a driving circuit via metal film wires. The back panel is divided so as to expose electrode terminals, and a groove part V-shaped in cross section is formed at the divided portion. The metal film wires are formed on the top surface of the back panel, and the electrode terminals and the metal film wires are connected by a conductive paste coated along the tilt surfaces forming the groove part. Partitions are disposed between the adjacent electrode terminals at the bottom of the groove part.

  • 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: 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.
