DISPLAY DEVICE WITH HOLOGRAPHIC DIFFUSER DISPLAY AND SEE-THROUGH LENS ASSEMBLY

摘要

A display device includes an optical diffuser configured to, in response to receiving image light, output diffused image light (492) having a same polarization as the image light. The optical diffuser is also configured to transmit ambient light (490). The display device also includes an optical assembly (700) that includes a substrate (710), a reflector (712) coupled to the substrate, and a beam splitter (714) 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.
