We have proposed and developed e‐Tile for wall decoration and ornaments for interior/exterior. A prototype of 2 m x 2 m large energy‐saving reflective panel was realized by arraying 400 e‐Tiles on a flat plane. Prototypes of cubic displays were also realized by constructing e‐Tiles to cubic shape. Artistic display effects and 3D impression could be found in these cubic prototypes. We hope e‐Tile is a promising solution to extend the application field of e‐Paper to decorative use including architectural applications. [ABSTRACT FROM AUTHOR]

Dual screen e‐Paper is expected to be useful when creating documents using reference documents. This study evaluated performances of referencing conditions using paper, e‐Paper, and LCD and suggested that the working conditions using dual screen e‐Paper brought almost the same performance as the working conditions using paper as a reference.

"e‐Tile" is introduced as a novel concept for large area displays. A typical e‐Tile configuration, in which 100 pixels are mounted on a 100 mm square board, is designed and practically prototyped. Assuming a relatively large pixel size on the electronic tile, the relationship between the viewing distance and the impression of image quality was studied by calculations and subjective evaluations.

We have introduced a novel concept for large area displays, "e‐Tile". A typical e‐Tile configuration, in which 100 pixels are mounted on a 100 mm square board, is designed and prototyped. One promising application is an unobtrusive information board, which is far less annoying than the conventional vivid LED/LCD in public spaces. [ABSTRACT FROM AUTHOR]

We have evaluated performances and subjective impressions of paper, LCD tablet, and e‐Paper during study tasks of reading and writing on each medium. Paper showed general superiority in correct answer rate, processing speed, and most of subjective impression. It should also be noted that e‐Paper showed better correct answer rate than tablet.

Projected image on a screen is not always vivid enough when it is projected in a bright room. We generally have to choose either vivid image in a cark room or dull image in a bright room. We have suggested a new projection system which can realize high contrast image projection in a bright room. It is consisted of electronic paper screen, projector, and light-emitting diode room light. The electronic paper (e-Paper) screen alternates its whole surface white/black with 120 Hz. Room lights are controlled with the same frequency of 120 Hz with the opposite phase as that of the e-Paper screen. We have confirmed that our new system has achieved higher contrast than the conventional projection system and also enough readability of paper documents in the room simultaneously. We have thus confirmed that our new system can bring an ideal condition, for audience, which can realize a vivid image projection in a bright room. [ABSTRACT FROM AUTHOR]
