Abstract (en)

[origin: WO2021062075A1] Light-transmissive conductors including oriented conductors disposed in a light-transmissive polymer having a volume resistivity between 1x1010 ohm-cm and 1x104 ohm-cm. The oriented conductors typically have very high conductivity along their length. Light-transmissive conductors described herein are well-suited for front electrodes for electro-optic displays, especially elongated displays in the shape of ribbons, stripes, or rulers.
