Abstract
A light guide plate for a backlight comprises a light transmissive medium. The light transmissive medium preferably has two pairs of opposing sides and a top surface. Also provided is a plurality of interleaved regions of elongated light extraction features on the top surface of the light transmissive medium. Each light extraction figure is configured to extract light injected into the light guide plate and into a direction away from the top surface of the light guide plate. Each elongated light extraction feature has a long dimension and a short dimension. The light extraction features in a first set of the regions are arranged with their long dimension orthogonal to the long dimension of the light extraction features in a second set of the regions.
