ABSTRACT:
An electronic device has a plurality of segment drivers for driving a liquid crystal display panel and a control unit. Each of the segment drivers has a display memory for storing display data. The control unit outputs address data and display data when the control unit produces an image to be displayed on a display. In case the segment drivers receive address data, each segment driver determines whether it is addressed or not by decoding a data piece of the address data. Then, in case the segment drivers are addressed, they write the input display data in the display memory on the basis of the address data.
