Patent ID: 8238024

Claim:
An arrangement for display with selectable three-dimensionally visible or two-dimensional modes, comprising: an illuminating device emitting light distributed over an area; a filter array, arranged on the image viewing side of the illuminating device, that imparts a structure to the light originating from the illuminating device by use of an arrangement of transparent and opaque area segments; a transmissive image display device arranged on the image viewing side of the filter layer; a diffusing layer arranged on the image viewing side of the image display device, the diffusing layer and the image display device substantially rigidly connected to each other; wherein a distance α between the filter array and the diffusing layer is variable, such that in a first position, in which the diffusing layer is arranged at a distance from the filter array, the structure imparted by the filter array to the light originating from the illuminating device is essentially cancelled, and a two dimensional image is shown on the image display device in the full resolution provided by it; and in a second position, in which the diffusing layer is arranged in close proximity to the filter array, the structure imparted by the filter array to the light originating from the illuminating device is essentially not cancelled, such that the image display device shows an image that is seen in three dimensions.
