The present invention relates to an autostereoscopic display device, comprising an imaging layer (9) and a lens layer (10). The lens layer (10) serves to project different content from the imaging layer (9) to the left and right eyes, respectively, of a user. The lens layer (10) comprises lens cells (12), enclosing two fluids (13, 14) with different refractive indices. The shape of the interface between the fluids may be changed using electrowetting, by means of two individually controllable electrodes (21, 22) at the sides of each lens cell (12). The display device further comprises a user head tracking device and means for controlling the lens cell electrodes depending on a detected user head position. This allows the display device to display a correct 3D-image, even if the user moves his head.
Display device, comprising an imaging layer with a plurality of picture elements and a lens layer comprising a plurality of lens elements for projecting light from different picture elements in the imaging layer to the left and right eyes of a user in order to provide an autostereoscopic effect, wherein each lens element comprises at least one lens cell which defines a closed space, having a front wall, facing the user, a back wall facing the imaging layer and side walls, connecting the back and front walls, wherein the side walls of each lens cell comprise at least a first and a second-individually controllable electrode, the closed space being filled with first and second immiscible fluids having different refractive indices, each cell comprising means for varying the radius of curvature and/or tilt of the interface between the first and second fluids, the first and second fluids serving to refract incident light such that the lens cell functions as a positive lens having a spherical shape via controllable contact angles with the side walls of the lens cell by varying said first and second individually controllable electrodes voltage potentials on said side wall electrodes, the display device comprises a tracking device for determining the position of a users head, and controlling means for controlling potentials of said first and second electrodes based on said position.
