Abstract
A display system includes a display panel having matrix electrodes with scanning lines and information lines, a display information storage memory for storing display information, and a controller for comparing the information read out from the display information storage memory with write display information to be written in the display information storage memory. The controller stores address information for designating a scanning line corresponding to write display information different from the readout information, scans the scanning line corresponding to the stored address information for a predetermined period of time and controls the matrix electrodes such that only a scanning line corresponding to the stored address information is interrupted after a lapse of the predetermined time period.
Claims8
A display system comprising:
- a. a display panel having matrix electrodes comprised of scanning lines and information lines;
- b. a display information storage memory for performing write access of transmitted write data and for performing read-out access of stored read out data;
- and
- c. control means for comparing the write data with the read out data, for performing a first sequence of scanning a scanning line corresponding to a partial region in a display image frame at a changing display at the partial region and for performing a second sequence of interlace refresh scanning the scanning line in the display image frame at a non-changing display on the display image frame, wherein the first sequence is interrupted when a predetermined time of the first sequence elapses, and therefore the second sequence is performed.
