Electrochromic display cell II

摘要

An electrochromic display cell is described which has a front electrode of an electrochromic material, especially tungsten trioxide or iridium oxide, layered on a support surface and a rear electrode of vitreous carbon layered on a support surface. The rest potential and large capacity of the rear electrode permit a fast image cycle time at the front electrode and obviate the need to reverse potential polarity during cycling.
