ABSTRACT:
A display apparatus includes a display panel having a scanning line and an information line and circuitry for generating and outputting image information periodically. A horizontal synchronizing signal determining a single period of the image information is output sequentially, with an interval between sequential outputtings. A writing time necessary for writing image information on the scanning line is determined and the writing time is divided by a corresponding interval of the horizontal synchronizing signal to obtain a quotient. The quotient is then rounded up into the next highest integer N. The apparatus then calculates a thinned out value (N-1), thins out the image information during a time corresponding to a number of periods based on the thinned out value and transfers the thinned out image information to the display panel. As a result, proper synchronization between the supply of data and the scanning of the display is provided, even for low frequency, high definition scanning.
