Abstract
Abstract A display apparatus includes a display panel having a display picture area formed by scanning electrodes and data electrodes arranged in a matrix. A display data storage memory stores data supplied from a display data input device. A controller controls the display data storage memory to store the moving display data. The controller also supplies address data for designating only the 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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
102 words
A display system, comprising: (a) a display panel having an electrode matrix comprising scanning lines and data lines; (b) a display data storage memory for storing display data supplied from a display data input device; and (c) control means 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.
Claim 2
Dependent Claim
102 words
A display system, comprising: (a) a display panel having an electrode matrix comprising scanning lines and data lines; (b) a display data storage memory for storing display data supplied from a display data input device; and (c) control means 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.
Claim 3
Dependent Claim
24 words
A display system according to claim 1, wherein said display panel comprises a ferroelectric liquid crystal disposed between the scanning electrodes and data electrodes.
Claim 4
Dependent Claim
119 words
A display system, comprising: (a) a display panel having an electrode matrix comprising scanning lines and data lines; (b) a display data storage memory for storing display data supplied from a display data input device; and (c) control means for, when display data supplied form the display data storage memory is static image display data or scrolling display data and image data inputted to the display data storage memory is cursor or mouse display mark data, storing address data for designating only scanning lines corresponding to the cursor or mouse display mark data, transferring the stored address data and controlling the electrode matrix so as to scan only the scanning lines on which the moving display data is written.
