AUTOSTEREOSCOPIC DISPLAY SCREEN EQUIPPED WITH A VERY HIGH-DEFINITION PIXEL PANEL

Abstract

AUTOSTEREOSCOPIC DISPLAY SCREEN EQUIPPED WITH A VERY HIGH DEFINITION PIXEL PANEL The invention relates to a screen (10) for displaying an autostereoscopic image with N viewpoints ordered from 1 to N, consisting of a series of even viewpoints and a series of odd viewpoints, the screen comprising a panel (30) of pixels arranged by rows (L1, L2, L3, L4) and by ordered columns, each pixel being composed of a plurality of active sub-pixels (SP) of different colors, each assigned to a viewpoint of the image; an ordered array (40) of cylindrical lenses (42) mounted on said pixel panel, each lens being inclined with respect to the columns of the panel at an angle (α) equal to arctan (1 / 6) so as to be able to interleave said series of even viewpoints and said series of odd viewpoints of the autostereoscopic image.

width approximately equal to the width of the active sub-pixels of the adjacent columns, said process being characterized in that it comprises: - the mounting of an ordered array (40) of cylindrical lenses (41, 42) on said pixel slab, each lens being inclined with respect to the columns of the slab by an angle (a) equal to arctan(l / 6), - if N is an even integer, the assignment under each lens (41, 42) of the grating, of the viewpoints of one of the two series of even or odd viewpoints to the odd lines (L1, L3) of the slab and the assignment of the viewpoints of the other series of viewpoints to the even lines (L2, L4) of the slab, - if N is an odd integer, the assignment, under each odd lens (41) of the grating, of the viewpoints of one of the two series of even or odd viewpoints, called the first series, to the odd lines (L1, L3) of the slab and the assignment of the viewpoints of the other series, called the second series, to the even lines (L2, L4) of the slab, and the assignment under each even lens (42) of the grating, of the viewpoints of said second series to the odd lines (L1, L3) of the slab and the assignment of the viewpoints of the first series to the even lines (L2, L4) of the slab, so as to interleave said series of even viewpoints and said series of odd viewpoints of the autostereoscopic image so that each lens (41, 42) of said lenticular array allows decoding a viewpoint of the autostereoscopic image by reading the subpixels encoding this viewpoint of the image, one line out of two, the intermediate lines for this viewpoint being formed from the opaque inactive areas of the subpixels of the adjacent viewpoints.
