Sub-Pixelated Color Realization of Reflective Electronic Display Using Partially Color-Addressable Technology
Partially addressable technology to realize a colorized image onto a glass substrate or plastic film in reflective electronic paper display is accomplished by the particle-moving method. This image panel includes upper and lower substrates with cells surrounded by rib patterns and filled with charged color particles. Mold substrate is prepared with the same condition as that of the lower substrate. The electric field between the mold and upper/lower substrates is used in this study, along with the image force of the conductive electrode. This addressable technology can be easily applied to any image panel, including transparent film. The feasibility of this technology is shown as a resultant reflective display panel with its fabrication process. We also ascertain that partially-addressed particles with a two-contrast color image are transferred from the mold substrate to the upper substrate of the panel via the particle-moving method.
