ABSTRACT:
A device for providing large area uniform illumination of display panels comprises a light transmitting member including a light receiver for receiving light from a light source and reflecting that light within the light transmitting member in at least a first direction parallel to a first axis and parallel to the plane of the light transmitting member. A plurality of first reflectors reflect a first portion of the light from the first direction to an exit direction orthogonal to the plane of the light transmitting member and reflect a second portion of the light from the first direction to a second direction parallel to the plane of the light transmitting member and parallel to a second axis that is perpendicular to the first axis. A plurality of second light reflectors reflect the light from the second direction to the exit direction.
