摘要： There is provided a driver for a display device comprising a plurality of pixels. The driver is arranged to drive the display device to display a hologram of a picture on the plurality of pixels such that, when the display device is suitably illuminated, a holographic reconstruction of the picture is formed. The holographic reconstruction comprises a plurality of image points. The hologram is arranged such that each image point of the holographic reconstruction is formed using a contiguous group of pixels of the display device. Each contiguous group of pixels has a first shape comprising a first side and a second side. The first and second sides are arranged such that, if the first shape is replicated, a respective first side of a first replica of the first shape is suitable for cooperating with a respective second side of a second replica of the first shape.

摘要： There is provided a driver for a display device comprising a plurality of pixels. The driver is arranged to drive the display device to display a hologram of a picture on the plurality of pixels such that, when the display device is suitably illuminated, a holographic reconstruction of the picture is formed downstream of the display device. The holographic reconstruction comprises a plurality of image points. The hologram is arranged such that each image point of the holographic reconstruction is formed using a contiguous group of pixels of the display device. Each contiguous group of pixels comprises less than 5% of a total number of pixels of the display device.
