Abstract:
1. A display device switchable between a single view mode and a multiview mode, the display device comprising: a display panel having an array of display pixels elements for producing a display; and an imaging arrangement provided over the display panel that is at least partly electrically switchable to provide the single view mode or the multiview mode, wherein the multiview mode the imaging arrangement comprises lenticular lens areas which direct the output from different display pixel elements to different spatial positions within a field of view of the display device, and wherein the imaging arrangement comprises: first and second optically transparent substrates, a liquid crystal layer sandwiched therebetween, and in-plane switching electrodes arranged at a side of said first substrate comprising coplanar parallel electrode lines, wherein the electrode lines are arranged as a plurality of sets of parallel lines, each set defining a lenticular lens area, wherein each set comprises first electrode lines at the opposite boundaries between the lenticular lens area and adjacent lenticular lens areas, and at least a first pair of electrode lines disposed between the opposite boundaries and symmetrical about the centre of the lenticular lens area, wherein each set comprises at most six electrode lines between the opposite boundaries in addition to the first electrode lines at the boundaries, wherein in a 2D mode, the liquid crystal molecules of the liquid crystal layer are oriented perpendicular to the electrode lines, and wherein the first electrode lines are wider than the electrode lines of the first pair of electrode lines, and the width of each of the electrode lines within the lenticular lens area has a width that is narrower than any other electrode line in the lenticular lens area that is positioned at a greater distance from the centre of the lenticular lens area.
