Display system for selectively designating scanning lines having moving display data thereon
First Claim
1. A display apparatus, comprising:
- (A) a display panel having a display area defined by a plurality of pixels arranged as an electrode matrix in a plurality of rows and a plurality of columns, each pixel comprising a pair of oppositely disposed electrodes and a liquid crystal disposed between the electrodes, a plurality of scanning lines each commonly connecting pixels arranged in a row, and a plurality of data lines each commonly connecting pixels arranged in a column;
(B) drive means for applying a scanning signal to the scanning lines, and for applying data signals to the date lines in synchronism with the scanning signal; and
(C) control means for, in a period of non-rewriting a display in the whole display area, refreshing the whole display area by scanning the scanning lines for the whole display area according to an interlaced scanning scheme, and, when a demand of displaying a motion picture in a window area occurs, intermitting the whole display area scanning, designating the window area by designating a limited number of scanning lines, repeatedly scanning the limited number of scanning lines according to a non-interlaced scanning mode, thereby to effect a motion picture display selectively in the window area, and interrupting the repeated scanning for the motion picture display when the number of scanning lines for the motion picture display reaches a prescribed number of scanning lines.

Abstract
A display apparatus, including a plurality of pixels arranged in a plurality of rows and a plurality of columns, each pixel including a pair of oppositely disposed electrodes and a liquid crystal disposed between the electrodes, a plurality of scanning lines each commonly connecting pixels arranged in a row, and a plurality of data lines each commonly connecting pixels arranged in a column, drive means for applying a scanning signal to the scanning lines and applying data signals to the data lines in synchronism with the scanning signal, a display data storage memory for storing display data supplied from a display data input device, a control for, when display data supplied from the display data input device is moving display data, controlling the display data storage memory to store the moving display data and supply address data for designating only scanning lines corresponding to the moving display data so as to control the electrode matrix to scan only the scanning lines on which the moving display data is written.
