<p>A reflective display (10) having a plurality of approximately hemispherical high refractive index (η1) transparent hemi-beads (14) substantially covering and protruding inwardly from a transparent sheet's (12) inward surface. The transparent sheet, which has an outward viewing surface (17), has a refractive index (η2) which can be low (i.e. η1≈1.92 and η2≈1.59). A member is selectably moved into an intense evanescent wave region at the hemi-beads' inward side to selectably frustrate substantial total internal reflection of light rays. The member can be a plurality of light scattering particles (26) suspended in a low refractive index (η3≈1.27) electrophoresis medium (20) and electrophoretically moved into or out of the intense evanescent wave region.</p> |
