AUTOSTEREOSCOPIC DISPLAY DEVICE Russian patent published in 2016 - IPC H04N13/04 G02B27/22 

FIELD: image forming device.

SUBSTANCE: autostereoscopic display device has a display device having array of spaced pixels (50), optic device comprising array of columns (51) of light guides and autostereoscopic lens device (49) containing multiple biconvex lenses above the light guide device. Columns (51) of light guides contain a side wall, which tapers outwardly to define the shape of a funnel with a pixel or pixels at the smaller base of the funnel. Biconvex lenses pass in the direction of the pixel column or are inclined at an acute angle to the direction of the pixel column. Each lens covers multiple widths of columns of pixels, which differently limit the angular distribution of light in different sides from the underlying pixel.

EFFECT: reduced crosstalk on the display.
