  • Patent number: 7679593
    Abstract: A display device which has a liquid crystal display which has a plurality liquid crystal pixels arranged in a matrix and which writes an image thereon after resetting the liquid crystal. The method of writing on the liquid crystal display can be selected from driving methods according to interlace scanning in which a frame is divided into a plurality of fields and writing by interlace scanning is performed and driving methods according to sequential scanning in which scanning lines are subjected to writing serially. When high-speed writing is required, for example, when display of a motion picture, display of inputted letters or scroll display is desired, one of the driving methods according to interlace scanning is selected. In interlace scanning, based on the end of a blackout state of a scanning line in a field, selection of a scanning line in the next field for writing is started.

  • Patent number: 6888522
    Abstract: An information display apparatus which has a liquid crystal display which uses chiral nematic liquid crystal with a memory effect and can be driven by a matrix driving method. The screen of the display is divided along a scanning line into a still picture display area and a motion picture display area. The information display apparatus may have a first display and a second display on one screen. The first display is a reflective type liquid crystal display with a memory effect, which has an advantage of saving energy, and is used exclusively to display a still picture. The second display is a liquid crystal display which requires only a short time for writing. Information to be written in a short time, such as inputted information, is displayed on the second display.

  • Patent number: 6697039
    Abstract: The disclosed herein is an information display apparatus having first and second liquid crystal displays on a common support plate. Each of the liquid crystal displays includes a plurality of pixels defined by a plurality of scanning electrodes and a plurality of signals electrodes. The scanning electrodes of the first liquid crystal display are respectively connected to the scanning electrodes of the second liquid crystal display so that both of the liquid crystal displays are commonly and simultaneously scanned by a scanning driver commonly provided to the liquid crystal display. The support plate is provided with a folding area between the first and second liquid crystal displays whereby the information display apparatus is capable of carrying with folding and of using with opening just like a conventional book.
