Patent ID: 8531439

Claim:
A switchable display device arranged to switch between a two-dimensional view mode and a three-dimensional view mode, the switchable display device comprising: a structure of light generating elements for generating light on basis of respective driving values; and optical directory means for directing the generated light in dependence of an actual view mode, the actual view mode being either the two-dimensional view mode or the three-dimensional view mode, the switchable display device being arranged to switch between the two-dimensional view mode and the three-dimensional view mode at a predetermined frequency and to alternately display: two-dimensional image data by providing corresponding driving values to at least a first part of the structure of light generating elements, while the optical directory means are in the two-dimensional view mode; and three-dimensional image data by providing corresponding driving values to at least a second part of the structure of light generating elements, while the optical directory means are in the three-dimensional view mode, the second part of the structure of light generating elements being complementary with the first part of the structure of light generating elements, wherein the periods during which three-dimensional image data is displayed are substantially equal to or substantially two times as long as the periods in which two-dimensional image data is displayed.
