Abstract: An autostereoscopic display device comprising a view forming module in registration with an image forming means. The image forming means has an orthogonal array of display pixels spatially defined by an opaque matrix. The view forming module provides at least two optical functions, namely a view forming function and a brightness non-uniformity reducing function. The view forming function modifies the direction of outputs of the display pixels such that the outputs of groups of the display pixels are projected in respective different directions as a plurality of views. The brightness non-uniformity reducing function spreads the outputs of the display pixels.

Abstract: The invention relates to an illumination system (10), a backlighting system and a display device. The illumination system comprises a light source (20) configured to emit light via a light guide (30) to a light exit window (40) of the illumination system. The light guide has a front wall (32) arranged opposite a rear wall (34) so as to guide light in a direction substantially parallel to the front wall. A distance (D) between the light guide (30) and the light exit window (40) reduces towards an edge (42) of the light exit window (40). The light guide (30) further comprises a light entrance window (36) for receiving the light from the light source which is arranged away from the edge of the light exit window. The illumination system according to the invention has, inter alia, the effect that its thickness may be reduced at the edge of the light exit window.

Abstract: A multi-view autostereoscopic display device comprises: a backlight having a plurality of backlight areas arranged in a width direction of the display device; a spatial light modulator arranged over and in registration with the backlight, the spatial light modulator having an array of display forming elements arranged in rows and columns for modulating light received from the backlight; and a view forming layer arranged over and in registration with the spatial light modulator, the view forming layer having a plurality of view forming elements arranged in the width direction of the display device, each view forming element being configured to focus modulated light from adjacent groups of the display forming elements into a plurality of views for projection towards a user in different directions. The backlight is switchable to activate different ones of the backlight areas in different portions of a driving cycle of the display device so that, in the different portions of the driving cycle, modulated light from the active backlight areas is incident on each view forming element with respective different angles of incidence. In this way, the overall viewing angle or the effective three dimensional display resolution may be increased.

Abstract: A display system, comprises a multi-view display panel (10) adapted to display different images to different viewers in different directions. Imaging means (16) monitors viewers within a field of view and the display output is varied in dependence on the monitoring information provided by the imaging means. The invention thus provides a display display system which captures viewer information and uses this to control the display of multiple images at appropriate respective viewing angles. This enables information to be tailored to a particular viewer's characteristics or enables a user to be tracked as they move. Thus, different viewers can have personalised information when watching different views of the same display. This provides a dynamic view allocation system.
