    摘要： 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.

    摘要： 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.

    摘要： An auto-stereoscopic display device which addresses the problem of how to provide an improved three dimensional effect without degrading the resolution of the views. The auto-stereoscopic display device comprises: image forming means having an array of display pixels for producing a display; view forming means positioned in registration with the image forming means and having an array of view forming elements, the view forming elements each being configurable to focus the outputs of groups of the display pixels into a plurality of views projected towards a user in different directions; and view deflecting means positioned in registration with the view forming means, the view deflecting means being arranged to selectably change the directions in which the plurality of views are projected towards the user. The view deflecting means comprise at least one birefringent prism having a first refractive index for light having a first polarization direction and a second refractive index for light having a second polarization direction. The view deflecting means further comprise a polarization switch in registration with the birefringent prism for providing the birefringent prism with display light having the first or second polarization direction. Specific arrangements of the image forming means, the view forming means and the view deflection means provide an even distribution of pixels and virtual pixels associated with the deflected views

    摘要： An image display including a touch-sensitive display, that creates tactile sensation and movement of an object (3-2) along its surface is provided. Actuators including conductive rods (4-111, 4-112) attached together may be used, such that each rod of the actuator (4-11) may increase or decrease in size when current is applied to that rod to cause the actuator to bend toward a specified direction. Also, an image display that includes ball bearings (1-10) whose rotation is controlled by driving magnets (1-21, 1-22) to cause an object to move is provided. Further, air holes (3-11) tilted in various directions to control object movement by air pressure may be provided. Moreover, rods (3-10) may be moved up or down as activated by driving magnets (2-20). The actuators, rods, ball bearing assemblies, or holes may provide touch sensitivity for the image display.
