Abstract
A projector and display apparatus using a holographic optical element are provided. The projector includes a first display panel configured to emit a first beam of a first image, a second display panel configured to emit a second beam of a second image, a first transmissive holographic optical element configured to separate the first beam into a first diffracted beam and a second diffracted beam such that pixels of the first image overlap each other, a second transmissive holographic optical element configured to separate the second beam into a third diffracted beam and a fourth diffracted beam such that pixels of the second image overlap each other, a reflective holographic optical element configured to diffract and reflect the third and fourth diffracted beams in the same direction as the first and second diffracted beams such that the first image and the second image at least partially overlap each other, and a projection lens.
