Beschreibung
Zusammenfassung:	A switchable autostereoscopic display comprises: an array of pixels lined with a view altering lens stack; a switchable liquid crystal layer arranged between the array of pixels and the view altering lens stack; a main linear grid of elongate electrodes; a first sub-grid of electrodes arranged parallel to and between the array of pixels and the main linear grid of elongate electrodes, wherein the first sub-grid is spaced apart from the main linear grid; a second sub-grid of electrodes arranged parallel to and spaced apart from the first sub-grid and parallel to the main linear grid to provide a capacitive touch location sensor and wherein the elongate electrodes, each having a width g, of the main linear grid are arranged at a pitch p and wherein the ratio g/p is at least 0.75.
