Abstract: A beam shaping device (1; 50; 60) comprising first (3) and second (4) substrates, a liquid crystal layer (2) sandwiched between the substrates, and a first electrode layer (5; 51) provided on a side of the first substrate (3) facing the liquid crystal layer (2). The beam shaping device is controllable between beam shaping states, each permitting passage of light through the beam shaping device, and further comprises an insulating layer (7) covering the first electrode layer (5; 51) and a second electrode layer (6; 53) provided on top of the insulating layer. The second electrode layer (6; 53) comprises a conductor pattern exposing a portion of the insulating layer (7). The beam shaping device is configured in such a way that application of a voltage (V) between the first (5; 51) and second (6; 53) electrode layers causes liquid crystal molecules comprised in a portion of the liquid crystal layer (2) corresponding to the exposed portion of the insulating layer to tilt in a plane perpendicular to the liquid crystal layer, resulting in a local refractive index gradient, thereby enabling shaping of a beam (8) of light passing through the beam shaping device.

Abstract: A beam shaping device (1; 31) comprising first (3; 33) and second (4; 37) optically transparent substrates, a liquid crystal layer (2; 36) sandwiched there between, and first (5; 34) and second (6; 35) electrodes arranged on a side of the liquid crystal layer (2; 36) facing the first substrate (3; 34). The beam shaping device (1; 31) is controllable between beam-shaping states, each permitting passage of light through the beam-shaping device in a direction perpendicular thereto. The beam shaping device (1; 31) is configured in such a way that application of a voltage (V) across the first (5; 34) and second (6; 35) electrodes results in an electric field having a portion essentially parallel to the liquid crystal layer (2; 36) in a segment thereof between neighboring portions of the electrodes (5, 6; 34; 35) and extending substantially from the first substrate (3; 34) to the second (4; 35) substrate. In this way a relatively high refractive index gradient can be obtained across short distances, which enables a very efficient beam shaping. The electric field can be achieved by utilizing electrodes provided on one side of the liquid crystal layer, in a so-called in-plane configuration. The device can be used in an autostereoscopic display device, for switching between 2D and 3D modes.

Abstract: The invention relates to a transflective LCD incorporating a partial mirror (224) as the transflector. In the transmissive display mode, light from a backlight system (240) passes apertures (226) in the transflector (224). According to the invention, recycling of light to the backlight system (240) is improved by substantially only polarizing light that passes an aperture. This is achieved by means of a patterned polarizer (222) extending over the apertures in the partial mirror.
