Abstract: A multi-view display is switchable between single view and multi-view modes, and uses lenticular means (9) arranged over the display panel which comprise birefringent electro-optic material (62) adjacent a non-switchable optically transparent layer (60). The non-switchable optically transparent layer (60) has a refractive index (n) substantially equal to the extra ordinary refractive index of the birefringent electro-optic material (62).
In the single view mode, the birefringent electro-optic material (62) defines a non-switched state, and the polarization (64) of the light output from the display panel and incident on the lenticular means is linear and aligned with the optical axis of the birefringent electro-optic material (62) at the surface where the display output light is received. In the multi-view mode, the birefringent electro-optic material (62) defines a switched state in which the optical axis is aligned perpendicularly to the display output surface.

Abstract: Autostereoscopic display device comprising a backlight (66), a display panel (62) comprising rows and columns of pixels and a lenticular arrangement (60, 64), wherein the backlight (66) provides a striped output comprising stripes in the column direction or offset by an acute angle to the column direction the lenticular arrangement comprises a first lenticular lens array (60) on the side of the display panel (62) facing the display output for directing different display panel pixel outputs in different directions and a second lenticular lens array (64) on the opposite side of the display panel (62), facing the backlight (66), for providing collimation of the striped back-light output.

Abstract: A method of driving a display uses first and second illumination cycles of the display. In each cycle, a first set of pixels is illuminated with a first color and a second set of pixels is illuminated with a second color. The first and second colors of the two cycles together include at least three colors for forming an image. This method provides a sequential drive scheme, in that at least two cycles are used with different color properties. However, each cycle uses at least two different colors, so that each cycle is not a single color across the whole display area. In this way, the color sequence is alternated spatially as well as temporally.
