摘要： An aspect of the present invention provides a display device that does not hinder driving. An electronic mirror includes: an image display device capable of switching between 2D display and 3D display, the 3D display being carried out by a parallax barrier method; and a distance measuring device for measuring a distance from eyes of a user to a display screen of the image display device. The electronic mirror switches display from the 3D display to the 2D display in a case where the distance measured by the distance measuring device falls outside a predetermined range during the 3D display.

摘要： A stereoscopic display device is provided where the luminance variation encountered when the parallax barrier is switched is reduced for viewing from a wide region. The stereoscopic display device includes: a display panel that displays an image; a switch liquid crystal panel disposed to overlie the display panel and including a liquid crystal layer; a position sensor that obtains positional information about a viewer; and a control unit that receives the positional information from the position sensor and locally applies to the liquid crystal layer a first voltage for rendering the switch liquid crystal panel translucent and a second voltage for rendering the switch liquid crystal panel non-translucent to display a parallax barrier that depends on the positional information. The control unit includes a timing adjustment unit that delays a time point for switching from the lower one of the first voltage and the second voltage to the higher one relative to a time point for switching from the higher one to the lower one by a delay time that depends on the positional information.

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： 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.
