Switchable single-multiview mode display device

摘要

A 2D-3D switchable autostereoscopic display device has an imaging arrangement (109) electrically switchable between a 2D mode and a 3D mode, which comprises in-plane switching electrodes comprising coplanar parallel electrode lines. The electrode lines are arranged as a plurality of sets of parallel lines, each set defining a lenticular lens area. Each set comprises first electrode lines at the opposite boundaries between the lens area and adjacent lens areas, and at least a first pair of electrode lines disposed between the opposite boundaries and symmetrical about the centre of the lens area, wherein each set comprises at most six electrode lines between the opposite boundaries. This provides an electrode layout which is simple to manufacture and yet has been found to provide good optical lens quality.
