Abstract
A display device includes an optical diffuser configured to, in response to receiving image light, output diffused image light having a same polarization as the image light. The optical diffuser is also configured to transmit ambient light. The display device also includes an optical assembly that includes a substrate, a reflector coupled to the substrate, and a beam splitter coupled to the substrate. The optical assembly is configured to transmit the diffused image light at a first optical power by reflecting the diffused image light at the reflector and at the beam splitter and to transmit the transmitted ambient light at a second optical power that is less than the first optical power without reflection at the reflector or the beam splitter. A method for transmitting light through the display device is also disclosed.
