NEC Develops E-Paper With Multi-Tiling
NEC LCD Technologies have managed to successfully roll out multiple sizes (A3 and A4 equivalent) of electronic paper (e-paper) modules thanks to the microcapsule electrophoresis system. This electrophoresis system uses white pigment particles electrified with positive electrodes, while black pigment particles are electrified with negative electrodes. Individual pigment particles will be held in a clear microcapsule that is then moved around by applying voltage, resulting in a visible display. The e-paper modules tout to feature higher visibility and gradation when compared to most newspapers, and will feature a secure 16 step grayscale, white reflectivity of 43% and a contrast ratio of 10:1. Another plus point of this e-paper is the utilization of reflected light that helps produce wider viewing angles, increasing visibility under direct sunlight while removing the strain on viewers' eyes.
