摘要： 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.

摘要： Disclosed is a stereoscopic display device that can reduce moiré that occurs due to light-shielding areas in the aperture of pixels. The stereoscopic display device includes a display panel and a parallax barrier. The display panel has a plurality of pixels and displays a stereoscopic image. In the parallax barrier, the direction in which transmissive and non-transmissive parts are alternately arranged is the first direction and the lengthwise direction of the non-transmissive parts is the second direction. There is a boundary that extends in the second direction between two pixels next to each other in the first direction. There are light-shielding areas in the aperture of each pixel. There is a space between the boundary and the light-shielding areas. Of two pixels next to each other in the second direction, the light-shielding areas in the aperture of one pixel are shifted in the first direction with respect to the light-shielding areas in the aperture of the other pixel.

摘要： A liquid crystal (LC) device includes an optical stack arrangement including from the viewing side: a first electrode component; a first LC alignment layer; an LC layer; a second LC alignment layer; and a second electrode component. A voltage is applied to the LC device to create a potential difference between the first and second electrode components to switch an alignment of liquid crystals of selected portions of the LC layer from a first state when no voltage is applied to a second state when the voltage is applied. The first and second LC alignment layers are vertical alignment layers that induce a vertical alignment of the liquid crystals such that the first state when no voltage is applied is a vertical alignment state, and the liquid LC crystals switch to a planar alignment state as the second state when the voltage is applied. The first and/or second electrode components is a dual layer segmented electrode component comprising a first layer of electrode elements separated by inter-electrode gaps and a second layer of electrode elements separated by inter-electrode gaps, the first layer of electrode elements and the second layer of electrode elements being spaced apart in a viewing direction by an insulator layer.

摘要： A switchable view angle control device for a privacy view display system includes an electrically switchable view angle control LCD that is operable in a first state and a second state; a front polarizer located on a viewing side of the switchable view angle control LCD; and a polarized light source located on a non-viewing side of the switchable view angle control LCD that emits polarized light. When the switchable view angle control LCD in the first state, the view angle control device operates in a narrow angle view mode in which off-axis polarized light from the polarized light source is changed by the switchable view angle control LCD so that the off-axis light is absorbed by the front polarizer, and on-axis light passes through the switchable view angle control LCD and the front polarizer. When the switchable view angle control LCD is in the second state, the view angle control device operates in a wide angle view mode in which the polarized light from the polarized light source is scattered by the switchable view angle control LCD and passes through the front polarizer.
