We have fabricated prototype lightweight electronic ink displays on a conformable active‐matrix array sheet. The active matrix arrays were built using amorphous silicon thin film transistors and capacitors on a stainless steel foil substrate. These prototype displays possess a resolution of 40 dpi, with 52×64 pixels (active area 1.3 inch × 1.6 inch) on a 1.8 inch × 2.0 inch stainless steel substrate. The display possesses an ink on paper appearance, with wide‐viewing angle and good contrast ratio.
