ABSTRACT:
A driving technique is provided for an electro-optical display which includes an electrochromic material and a predetermined number of display segments, combinations of the display segments each defining a different one of a desired number display patterns. The electrochromic phenomenon is developed within the electro-optical display upon a flow of current supplied through the display segments. In transition of a visual display from a specific display pattern to another, current is applied to only the one or more display segments which are not common to the two display patterns, while no current is supplied to the one or more display segments common to the two display patterns.
