Autostereoscopic display with illuminating lines, light valve and mask

A method of displaying autostereoscopic images which comprises sending from a transmitter a series of modulated electromagnetic signals that are received by a light valve in a display unit wherein the light valve is in front of and parallel to a flat surface screen,

• said flat surface screen displaying a multiplicity of regularly spaced discrete, finite light emitting sites across its surface, said screen remaining dark between said emitting sites,
• said light valve in front of and parallel to said screen, said light valve having individual picture elements arranged in a grid pattern across its surface, there being a vertical column of individual picture elements for each light emitting site, said light emitting site being located behind said element,
• and said display unit has a mask comprised of alternating opaque and transparent to light sections, there being one transparent and one opaque section so situated in front of each individual picture element of said light valve whereby due to parallax effect a viewer's right eye can only perceive the light emitting lines through the transparent regions on alternate rows of individual picture elements and a viewer's left eye can only perceive the light emitting lines through the transparent regions on the remaining rows of individual picture elements.

In an autostereoscopic display unit the improvement which comprises

• (a) a flat surface screen displaying a multiplicity of regularly spaced discrete, finite light emitting sites across its surface, said screen remaining dark between said emitting sites, and
• (b) a light valve in front of and parallel to said screen, said light valve having individual picture elements arranged in a grid pattern across its surface, there being at least one pair of vertical columns of individual picture elements for each light emitting site, said light emitting site being located behind the boundary of said pair,
• said light emitting sites being disk or square shaped and arranged in a raster pattern grid.
