The conventional way of driving a lutetium phthalocyanine electrochromic display is to anodically write from the green state to the red#tan state. This results in a display with red-tan characters on a green background. Problems can arise in integrating this type of display on a silicon chip because of difficulties in designing the current sources in n-channel FET technology.
