Abstract
The invention relates to a 3 D display. The 3 D display comprises suspended particle devices with a suspension of elongated particles that align at a predetermined angle with incoming light beam. The display will allow information to be separated relevant to the left and right eye. An electronically controllable set of suspended particle devices adjusts the deflection angle of the outcoming light beam.
Claims29
An electro-optical cell (1, 18) comprising first and second support members (2, 3) at least one of which is transparent to optical radiation (6),
- a suspension of anisometric particles between the support members (5), and
- an electrode arrangement (11, 12) on at least the first support member (2) to apply a first electric field to the particle suspension (5) in such a manner that at least a major proportion of the particles (4) are aligned in an oblique configuration relative to the support members (2, 3) in a predetermined region thereof so as to guide obliquely the optical radiation (6) passing between the support members.
