Autostereoscopic display device

摘要

An autostereoscopic display device comprises a display (103) having an array of display pixels (105) and a view forming arrangement (109) of elongate elements which have a long axis which is slanted at an angle α to the column pixel direction, and the elements have a pitch of P times the width between pixels of the same color in different columns. The pitch P is selected to be: P=0.5·k·(1+S2) in which S=tan α, and k is a positive integer. This arrangement enables the resulting image projected in respect of each view to have a uniform and regular distribution of pixels across the image. This improves the visual appearance of the views.

1. An autostereoscopic display device comprising:
a display (103) having an array of display pixels (105) for producing a display, wherein the display pixels are arranged in rows and columns; a view forming arrangement for projecting a plurality of views each of which in a different direction, the view forming arrangement comprising elongate elements which have a long axis which is slanted at an angle α to the column pixel direction, and the elongate elements have a pitch of P times the width between pixels of the same colour in different columns, and wherein the pitch P is selected to be:
P=0.5·k·(1+S2) in which S=tan α, and k is a positive integer.
