Light emitting panel assemblies include one or more light emitting panel
members each having at least one pattern of optical deformities that may
be varied in size, shape, density, placement, angle, rotation and/or type
to obtain at least one light output distribution having a form or shape
of at least one of text, graphics, logo or image. At least some of the
optical deformities may be shaped or oriented preferentially to cause
different colored light propagating through the panel member in different
directions to create a multi-colored light output distribution. Also, a
plurality of panel members each having a different light output
distribution may be placed in overlying relation to one another to
produce a composite output distribution when viewed through the panel
members or a display overlying the panel members.
