20090073351 | DISPLAY MEDIUM, AND MANUFACTURING METHOD AND APPARATUS OF THE DISPLAY MEDIUM - A display medium including: a pair of substrates; a pair of electrodes disposed on the pair of substrates, and facing each other; and a functional layer and a display layer disposed between the pair of electrodes with an adhesive layer disposed between the functional layer and the display layer. The display layer includes a binder and microcapsules dispersed in the binder. The microcapsules have a polymer serving as a wall material, and a liquid crystal enclosed therein. A shape of an interface of the display layer at least on the side of the adhesive layer in a cross section along a thickness direction of the disposed layers is an irregular line having a distance between a highest protruding portion and a lowest depressed portion is from about 0.5 μm to about 2.0 μm. | 03-19-2009 |
20090159345 | DISPLAY MEDIUM AND WRITING APPARATUS - The present invention provides a display medium which prevents a decrease in reflectance during storage at high temperatures, and a writing apparatus using the display medium. A photoconductive layer | 06-25-2009 |
20090162575 | LIQUID CRYSTAL-CONTAINING COMPOSITION, AND LIQUID CRYSTAL DISPLAY DEVICE INCLUDING THE SAME - A liquid crystal-containing composition and a liquid crystal display device including the same, the liquid crystal-containing composition including a cholesteric liquid crystal and microcapsules containing the cholesteric liquid crystal, and having a wall component comprising at least one selected from the group consisting of polyurethane and polyurea, the wall component further including a first isocyanurate component having a cyclo ring structure and a second isocyanate component other than the first isocyanurate component. | 06-25-2009 |
20090191361 | LIQUID CRYSTAL-CONTAINING COMPOSITION AND LIQUID CRYSTAL DISPLAY DEVICE THEREWITH - A liquid crystal-containing composition includes a microcapsule. In the microcapsule, a liquid crystal is encapsulated by a shell material component containing polyurea. Monomer components included in the polyurea include a polyisocyanate component, a high molecular weight polyamine component and a low molecular weight polyamine component. | 07-30-2009 |
20090255985 | System for writing information and method of writing information - A medium writing apparatus obtains information to be written onto a recording medium, converts the information into a suitable writable format, and then writes the converted information onto the recording medium. An ID obtaining section obtains a medium ID from the recording medium, or through an input by the user. The medium ID and information indicating the place of the written information are sent to a server, and then stored as index information correlating them with each other. When the information written onto the recording medium is to be used at a later timing, the medium ID is identified, and the index information is obtained from the server. Therefore, the original information can be obtained so as to be easily reprocessed or reused. | 10-15-2009 |
20100164848 | LIQUID CRYSTAL-CONTAINING COMPOSITION AND LIQUID CRYSTAL DISPLAY DEVICE USING THE SAME - A liquid crystal-containing composition includes a cholesteric liquid crystal and a microcapsule wall that encapsulates the cholesteric liquid crystal, the microcapsule wall includes at least one material selected from polyurethane and polyurea, and the content of the microcapsule wall with respect to 100 parts by weight of the cholesteric liquid crystal is from about 0.1 parts to about 11 parts by weight. | 07-01-2010 |
20100165260 | LIQUID CRYSTAL-CONTAINING COMPOSITION AND LIQUID CRYSTAL DISPLAY DEVICE USING THE SAME - A liquid crystal-containing composition includes a first cholesteric liquid crystal having a peak wavelength of selective reflection in the range of from 600 nm to 800 nm and encapsulated in a microcapsule and a second cholesteric liquid crystal having a peak wavelength of selective reflection in the range of from 400 nm to 500 nm as the only liquid crystals, and the content of the second cholesteric liquid crystal with respect to the entire cholesteric liquid crystal content is from about 5 weight % to about 40 weight %. | 07-01-2010 |
