Abstract: A method of producing a lenticular device for an autostereoscopic display apparatus includes providing a substrate having a surface which corresponds in shape to a desired surface profile for the array of lenticular elements, and providing an optical layer mixture of an optically birefringent material and a polymer precursor over the substrate surface. The optical layer is exposed to a stimulus for polymerizing the polymer precursor to have at least a polymer surface layer, thereby enclosing the material between the polymerized material and the surface to define lenticular elements. This method allows a simple polymerization process, forming a single layer, to complete the LC cell formation in the desired lenticular array shape.

Abstract: There is disclosed an optical beam deflection arrangement which may be used in an autostereoscopic display device. The arrangement comprises a substrate; a first layer, for example formed of an optically isotropic solid and having a curved surface facing towards the substrate; and a second layer, for example formed of a liquid crystal material confined between the substrate and the first layer. An interface between the first and second layers may, for example, define an array of parallel lenticulars. A refractive index of the second layer, for light of a predetermined polarization, maybe switchable between a first value matching the refractive index of the first layer and a second value different to the refractive index of the first layer, to thereby selectably provide a beam deflection function.

Abstract: A method of manufacturing a shaped polymer device comprises forming a planar polymer layer over a substrate which has a lower coefficient of thermal expansion than the polymer layer; and shaping the polymer layer using a laser ablation process. This method uses a substrate with low thermal expansion to limit the expansion of the attached polymer layer when it is being shaped by a laser ablation process. In addition there is provided a lens structure for an *autostereoscopic display device comprising a substantially planar glass substrate and a polymer layer defining a lenticular arrangement provided over the glass substrate.

Abstract: An autostereoscopic display device includes a reflection layer for reflecting at least a portion of incident light, a polarization conversion layer arranged over the reflection layer, and an array of lenticular elements arranged over at least a portion of the polarization conversion layer and including a birefringent material. Light having a first state of polarization is configured to pass through the lenticular element array without substantial lenticular element focusing, where the polarization state is transformed by the polarization conversion layer such that the reflected light has a second state of polarization. Light having the second polarization state passes through the lenticular element array with the lenticular element focusing to provide multiple views to different viewing locations.

Abstract: A method of manufacturing a switchable liquid crystal device uses first and second foils (80,82). A bonding layer (100) is applied to the first foil by a lamination process and bonding takes place at predetermined portions of the bonding layer. These portions define at least one closed boundary (110). Those parts of the bonding layer other than at the predetermined portions are removed. After or during the foils are laminated together, the space enclosed by the closed boundary is filled with liquid crystal material (72) the structure is laminated onto a support substrate (92). The method uses foils as the opposing substrates, so that they can be processed using roll to roll and lamination processes.

Abstract: An autostereoscopic display apparatus comprises a lenticular array (20) mounted to a display panel (10) which is mounted to a backlight unit (12). A lateral securing member is (30) disposed directly between the backlight unit (12) and the edge of the lenticular array (20) to prevent relative movement in a direction parallel to the plane of the panel (10). The stack comprising the panel (10) and lenticular plate (20) is prevented from sliding during regular use and from vibration during transportation.

Abstract: An autostereoscopic display device comprises a display panel having an array of display pixels for producing a display. The display pixels are arranged in orthogonal rows and columns. The device also comprises an array of parallel lenticular elements positioned over the display panel. The lenticular elements have optical focal axes that are slanted at an angle to the display pixel columns. Display areas of the display pixels have edges that are substantially parallel to the lenticular element axes so that pixels of different views are prevented to be projected to the same viewing zone, thereby preventing crosstalk between views and reducing light intensity variations (due to varying amount of the opaque black mask which is imaged. The light intensity output also varies across each pixel display area in a direction perpendicular to the lenticular element axes.
