Abstract: A reconfigurable parallax barrier panel comprising an electro-optic material has first and second regions. The parallax barrier panel is configured in a first mode to address the first and second electrodes on the basis of at least one received drive signal such that: the first electrodes define, in the first region of the panel, a first parallax barrier array selected from a plurality of predetermined parallax barrier arrays; and the second electrodes define, in the second region of the panel, independently of the first parallax barrier array, a second parallax barrier array selected from the plurality of predetermined parallax barrier arrays, the second parallax barrier array being different to the first parallax barrier array. To obtain a good autostereoscopic 3-D viewing zone the pitch of a parallax barrier would ideally vary over the width of the parallax barrier panel as a function of viewing distance. This is impracticable to obtain in a practical parallax barrier panel, but the present invention can provide a change in barrier pitch at the boundary between the first region and the second region, and this effectively mimics a pitch that varies over the width of the parallax barrier panel as a function of viewing distance. A parallax barrier panel of the invention can provide improved 3-D viewing when the parallax barrier panel is incorporated in a display.

Abstract: A reconfigurable parallax barrier panel comprising an electro-optic material has a first region, a second region and a first compensation region. First electrodes are addressable to define, in the first region of the panel, a parallax barrier array selected from a plurality of predetermined parallax barrier arrays, and second electrodes are addressable define, in the second region of the panel, independently of the first parallax barrier array, a parallax barrier array selected from the plurality of predetermined parallax barrier arrays. Electrodes of the first compensation region are addressable to define, dependent on the first parallax barrier array and on the second parallax barrier array, at least one slit and/or at least one barrier between the first region and the second region. Where the first electrodes are addressed to define a first one of the predetermined parallax barrier arrays in the first region and the second electrodes are addressed to define a second, different one of the predetermined parallax barrier arrays in the second region, the electrodes of the first compensation region may define the at least one slit and/or at least one barrier to at least partially obscure any line artefact at the transition between the first one of the predetermined parallax barrier arrays and the second one of the predetermined parallax barrier arrays.

Abstract: A multiple view directional display has an image display panel, a parallax optic and a control unit. The control unit is configured to address the image display panel to display first and second images on respective sets of X adjacent columns of pixels or sub-pixels. The parallax optic comprises parallax elements configured to allow a first region of the image display panel having a width of Y adjacent columns of pixels or sub-pixels to be visible to a left eye of a viewer, where Y≧3 and X−Y≧3, and to allow a second, different region of the image display panel having a width of Y adjacent columns of pixels or sub-pixels to be visible to a right eye of the viewer. Parallax elements of the parallax optic are inclined with respect to columns of pixels or sub-pixels of the image display panel.

Abstract: A reconfigurable parallax barrier panel, for use in a display system with a 3D mode, includes a first substrate, a second substrate, and an electro-optic material positioned between the first and second substrates. The first and second substrates each respectively has a plurality of first and second electrodes, the electrodes being independently addressable from one another and comprising a plurality of electrode portions extending along a first direction and laterally spaced from one another along a second direction different from the first direction. The electrode portions of the first electrodes are arranged in a cyclic arrangement having a first pitch, and the electrode portions of the second electrodes are arranged in a cyclic arrangement having a second pitch that is different to the first pitch. The first and second electrodes are driven to generate different reconfigurable parallax barrier arrays corresponding to different viewing distances in a 3D mode of operation.
