Abstract

In this paper we give an overview on NTera's novel reflective display technology with real 'ink-on-paper' readability. Our technology is based on mesoporous wide-bandgap semiconductor films modified with self-assembled monolayers of electrochromic chromophores. The direct vicinity of each electrochromophore to the semiconductor allows its electronic addressing in the millisecond domain. The high molar extinction coefficient of the organic chromophores in conjunction with the extremely large specific surface area of the mesoporous semiconductor substrate allows to achieve deep colorations with high contrast ratios. Combined with a unique white reflector technology yielding reflectivities above 50 percent and excellent angular contrast independnece, oru displays show outstanding optical properties, comparable to those of ink on paper. Applying simple printing techniques these displays can be manufactured from commercially available nanomaterials like TiO₂ or other doped or undoped metal oxides. Along with favorable electronic properties like low power consumption and excellent open-circuit memory electrochromic displays seriously rival conventional LCD display applications.
