摘要:
An electronic display arrangement for taking light signals forming an image emitted from a miniature screen (2) and referred to as a screen image, and for conveying them to the eye (O) of a user to enable a virtual image (I) to be viewed, the arrangement having a miniature screen control device having an arrangement for subdividing a source image into N screen images (IE) and in that it includes a mosaicing device (3) having an exit viewport (10) and serving to convey the N screen images in a manner in which they are spatially offset from one another and time shifted from one another at a period (τ) shorter than the remanence time of the retina of the eye divided by N, each screen image (IE) being conveyed towards the eye of the wearer for viewing a virtual sub-image (IN), the N resulting and adjacent virtual sub-images together forming said virtual image (I) in full, said mosaicing device (3) being constituted by a light polarization control element (5) and by an element (7) for spatially reconstructing the virtual image (I). A mosaicing device has a light pipe (6) of material that is transparent in the visible domain and said light pipe is disposed between said control element (5) and said element for spatially reconstructing the virtual image.
