摘要:
Disclosed are embodiments of apparatus and methods that provide light emitting displays with improved wide angle color viewing. A plurality of light emitting elements is arranged in a predetermined pattern and collectively creates a viewing plane. A portion of the light emitting elements are disposed in a primary orientation while the remainder of the light emitting element are disposed in a complementary orientation. Each light emitting element in a primary orientation is adjacent to a light emitting element in the complementary orientation. The spatial light emission pattern of the primary orientation is complementary to the spatial light emission pattern of the complementary orientation. Adjacent pairs of primary-complementary oriented light emitting elements cancel a substantial amount of color variation that would otherwise be seen when one varies the gaze angle upon the viewing plane.
