Abstract
A multiple view display comprises a display device such as a liquid crystal device, a parallax optic such as a parallax barrier, and a controller. The device comprises rows and columns of pixels and the controller supplies image data for a first view to first ones of the pixels and second ones of the pixels such that the first and second pixels alternate in the rows and in the columns. The parallax optic comprises rows and columns of parallax elements with the arrangement of pixels and parallax elements being such that each element co-operates with a respective pair of first and second pixels adjacent each other in the same row to form first and second viewing regions. Each row of parallax elements is off-set in the row direction by half the horizontal barrier pitch. Such an arrangement allows wider angles between the viewing regions to be achieved.
