Abstract
A driving circuit is provided for an electro-optical display which includes an electrochromic material and a predetermined number of display segments, various combinations of display segments defining different desired display patterns. The electrochromic phenomenon is developed within the electro-optical display upon a flow of current supplied through the display segments. The driving circuit is constructed so as to supply a predetermined amount of the flow of current to the display segments during variations of the light absorption properties.
