Reversible electrochromic display device having a memory including a unit cell with working and counter electrode therein and means for applying an electric field across said electrodes and for reversing polarity. The electrochromic activity is derived from a doped polymeric resin having electrochromic active molecules covalently bonded thereto. The dopant is a non-electroactive ionic salt. It acts to increase switching speeds in potentiostatic writing modes.
可逆电致变色显示装置,其存储器包括一个单元池,其中有工作电极和对电极,以及在所述电极上施加电场并使极性反转的装置。电致变色活性来自掺杂聚合物树脂,该树脂具有共价键合的电致变色活性分子。掺杂剂是一种非电活性离子盐。它的作用是提高电位静电写入模式的开关速度。
