Switchable three-dimensional display
View Patent ↗A switchable three-dimensional display includes a display panel and a switchable parallax barrier. The switchable parallax barrier is configured over the display panel and includes a first substrate, a second substrate, an insulating layer, a common electrode, and a light-valve layer. The first substrate has a touch-sensing circuit. The second substrate has a plurality of control electrodes and is configured between the first substrate and the display panel. The touch-sensing circuit and the control electrodes are located between the first substrate and the second substrate. The insulating layer is configured over the first substrate and covers the touch-sensing circuit. The common electrode is configured on the insulating layer. The light-valve layer is configured between the common electrode and the control electrodes.
