Abstract
An autostereoscopic display apparatus comprises a display device (10), for example a matrix LC display panel, for producing a display output consisting of rows and columns of pixels (12) and lenticular means (15) at the output side of the display device comprising an array of lenticular elements (16) through which different groups of pixels, forming one or more stereoscopic pairs, are seen by respective eyes of a viewer. The lenticular means includes electro-optic material (38) having an electrically--alterable refractive index and which can be selectively switched to remove the action of the lenticular elements thereby allowing high resolution 2-D images to be viewed.
Claims9
An autostereoscopic display apparatus comprising an image display device for providing a display output composed of pixels in a row and column array and lenticular means comprising an array of lenticular elements for directing the outputs from respective groups of pixels in mutually different directions so as to enable a stereoscopic image to be perceived, characterised in that the lenticular means further comprises electro-optic material whose refractive index is switchable by selective application of an electrical potential thereto between a first value whereby the light output directing action of the lenticular elements in mutually different directions is maintained and a second value whereby the light output directing action is removed.
