Abstract:
A display panel assembly comprises a transflective holographic screen, i.e., a transparent screen that reflects light from a projection system, comprising at least a volume hologram, a first protective element and a second protective element, each arranged in contact with the volume hologram such that the volume hologram is sandwiched between the first protective element and the second protective element. The display panel assembly further comprises a projection system focusing an image on the volume hologram comprising at least projection optics, mounting means arranged to fixedly mount the projection system relatively to the transflective holographic screen. The volume hologram comprises a plurality of diffractive patterns disposed in sequence across the volume hologram, each of the plurality of diffractive patterns being configured to diffuse the light rays from the projection system in a determined direction corresponding to the specific diffractive pattern and oriented towards a position of an intended eye of a user wearing the display panel assembly.
Abstract:
Method for displaying an image being projected from a portable head-worn display comprising steps of emitting a plurality of light beams of different wavelengths (206, 301), directing the plurality of light beams to a scanning mirror (205), modulating in intensity each one of the plurality of light beams in accordance with intensity information provided from the displayed image whereby the intensity is representative of a pixel value within the image, scanning the plurality of light beams in two distinct axes with the scanning mirror (205) to form the image and redirecting the plurality of light beams to the eye using a holographic reflector (204) whereby the redirecting is dependent on the wavelength of the light beam, to create for each light beam an exit-pupil (212, 304) at the eye (210) that is spatially separated from the exit-pupils of the other light beams.
