Display apparatus including partial rewritting means for moving image display

A display apparatus, comprising:

• (a) a display panel having a display picture area formed by scanning electrodes and data electrodes arranged in a matrix;
• (b) drive means including first means for driving the scanning electrodes and second means for driving the data electrodes;
• and
• (c) control means for controlling the drive means so as to scan-select the scanning electrodes with skipping of one or more scanning electrodes apart for one vertical scanning drive of the scanning electrodes constituting the display picture area and scan-select the scanning electrodes without skipping for scanning drive of only a part of the scanning electrodes constituting the display picture area.

• (a) a display panel having a display picture area formed by scanning electrodes and data electrodes arranged in a matrix;
• (b) drive means including first means for driving the scanning electrodes and second means for driving the data electrodes;
• and
• (c) control means for controlling the drive means so as to scan-select the scanning electrodes with skipping of two or more scanning electrodes apart for one vertical scanning and scan-select non-adjacent scanning electrodes in at least two consecutive times of vertical scanning for scanning drive of the scanning electrodes constituting the display picture area and scan-select the scanning electrodes without skipping for scanning drive of only a part of the scanning electrodes constituting the display picture area.

A display apparatus, comprising:

• (a) a display panel having a display picture area formed by scanning electrodes and data electrodes arranged in a matrix;
• (b) drive means including first means for driving the scanning electrodes and second means for driving the data electrodes;
• and
• (c) control means for controlling the drive means so that, when a part of image data stored in an image data storage memory is rewritten, one vertical scanning of the display picture area of the display panel is completed based on image data before the rewriting, and thereafter a scanning selection signal is applied to only scanning electrodes corresponding to the rewritten image data in the memory.

• (b ) drive means including a first means for driving the scanning electrodes and a second means for driving the data electrodes;
• (c) a flag memory for setting one bit of ON or OFF data for each scanning electrode;
• and
• (d) control means for controlling the drive means so that a scanning selection signal is applied to only a prescribed number of a scanning electrodes corresponding to ON data in a first partial rewriting operation, and the scanning selection signal is applied to only the same prescribed number of scanning electrodes corresponding to the ON data is a second partial rewriting operation.

• (a) a display panel having a display picture area formed by scanning electrodes and data electrodes arranged in a matrix;
• (b) drive means including a first means for driving the scanning electrodes and a second means for driving the data electrodes;
• and
• (c) control means for controlling the drive means so that the scanning electrodes are driven alternately in a first period wherein a scanning selection signal is applied to the scanning electrodes with skipping of one or more scanning electrodes apart in one vertical scanning, and a second period wherein a scanning selection signal is applied to the scanning electrodes without skipping to effect one vertical scanning.

A display apparatus, comprising:

• (a) a display panel having a display picture area formed by scanning electrodes and data electrodes arranged in a matrix;
• (b) drive means including first means for driving the scanning electrodes and second means for driving the data electrodes;
• and
• (c) control means for controlling the drive means so that a scanning selection signal is applied to only a number of the scanning electrodes constituting the display picture area to effect a partial rewriting scanning drive, and the partial rewriting scanning drive is interrupted when the number of scanning electrodes in which the scanning selection signal is applied exceeds a prescribed number to start one vertical scanning of the whole display picture area.
