Electronic Tile as an Energy Saving Display Component

Abstract

Electronic tile (e-Tile) using electrophoretic type electronic paper display technology is expected to offer energy-saving wall-displays. We have prototyped e-Tile of 10cm square, and demonstrated 2m square display using 400 e-Tiles. Remarkably low power of 4wats for the 2m square display was confirmed. Sufficient durability of e-Tile for practical use was confirmed as results of continuous rewriting tests. A hybrid color display system using e-Tile and a projector was also proposed and demonstrated. In addition, prototypes of cubic displays of 10cm and 30cm cube were demonstrated as an example of expanding application, including 3D surfaces, of e-Tile.
