Abstract:
Upon completion of rewriting of a page of a document, a display apparatus having a display unit with memory switches to a low power consumption mode without rewriting the display on a display unit, and stops power supply to the display unit. When a page updating operation is performed in the low power consumption mode, the display apparatus supplies power to the display unit, and rewrites the display screen with the screen of the next page.
Abstract:
Display apparatuses 10A and 10B store at least one document file that is the same. When a keyword search is performed in the display apparatus 10A, a list of search results is displayed in the display apparatus 10A. When one of the search results in the displayed list is selected, the display apparatus 10A transmits information specifying a portion corresponding to the selected search result to the display apparatus 10B. The display apparatus 10B specifies a portion to be displayed on the document, using the information transmitted from the display apparatus 10A, and displays an image of the specified portion.
