ABSTRACT:
A display system includes a display panel provided with matrix electrodes composed of scanning lines and information lines, a first unit for transferring scanning line address information and image information corresponding to the writing into pixels of a scanning line, a second unit for delaying the transfer of the received image information and then latching the image information of a scanning line, and a third unit for designating a scanning line based on the received scanning line address information and storing the designation information of the designated scanning line. A fourth unit controls the second and third units so as to, when third unit designates a scanning line based on the received scanning line address information, synchronize the selective drive of the scanning line designated by the immediately preceding stored information for designating the scanning line with the drive of the information lines based on the image information latched by the second means, and selectively drives the scanning line designated according to the scanning line address information within the period of the synchronization.
