Abstract
Optical assembly comprises a light emitting panel member having opposite sides and an input edge for receiving light from light sources optically coupled to a different location along the input edge. On or in at least one of the sides of the panel member is a pattern of individual optical deformities that are varied throughout the pattern and shaped or oriented throughout the pattern to extract light propagating through the panel member in different directions for viewing from different angles through one of the sides of the panel member.
