Abstract
An autostereoscopic display device has display elements, each of which has an output light intensity distribution which has at least two non-zero light intensity levels, comprising a first light intensity at the centre of the display element area and a second lower light intensity at a periphery of the display element area. This means the light intensity drops more gradually at the pixel edges, so that the abrupt pixel edges are less visible despite the magnification provided by a lens arrangement of the autostereoscopic display device.
Claims11
An autostereoscopic display apparatus, comprising:
- a plurality of individually addressable display elements arranged in an array of rows and columns, wherein each display element comprises the smallest area which is for displaying a single pixel of image data of a single colour;
- and
- a lens arrangement for directing different views displayed simultaneously by the display elements to different spatial locations,
- wherein each display element has an output light intensity distribution which has at least two non-zero light intensity levels, comprising a first light intensity at the centre of the display element area and a second lower light intensity at a periphery of the display element area.
A method of operating an autostereoscopic display apparatus, wherein the apparatus comprises a plurality of individually addressable display elements arranged in an array of rows and columns wherein each display element comprises the smallest area which is for displaying a single pixel of image data of a single colour, wherein the method comprises:
- directing different views displayed simultaneously by the display elements to different spatial locations using a lens arrangement;
- and
- controlling the output light intensity distribution for each display element to have a first light intensity at the centre of the display element area and a second lower light intensity at a periphery of the display element area.
