An autostereoscopic display comprising: a display panel having an array of pixels arranged in rows and columns, for producing a display output, each of the pixels comprising at least two sub-pixels and each sub-pixel having a spatially separated lower half and upper half which share a column data line, an imaging arrangement configured for directing the output from different sub-pixels to different spatial positions so as to enable an autostereoscopic view of the display output; and a controller configured for controlling the output from the sub-pixel halves such that: in a frame time comprising a first and second sub-frame time, the display panel produces a frame of the display output, characterised in that : in a first sub-frame time, a first set of sub-pixel halves provides a first lower resolution sub-frame, and in a second sub-frame time, a second set of sub-pixel halves different from the first set of sub-pixel halves provides a second lower resolution sub-frame, wherein the first and second sub-frames together provide a complete higher spatial resolution frame with the information for enabling its autostereoscopic view, such that the complete spatial frame resolution is built up in a sequence. a display panel having an array of pixels arranged in rows and columns, for producing a display output, each of the pixels comprising at least two sub-pixels and each sub-pixel having a spatially separated lower half and upper half which share a column data line, an imaging arrangement configured for directing the output from different sub-pixels to different spatial positions so as to enable an autostereoscopic view of the display output; and a controller configured for controlling the output from the sub-pixel halves such that: in a frame time comprising a first and second sub-frame time, the display panel produces a frame of the display output, characterised in that : in a first sub-frame time, a first set of sub-pixel halves provides a first lower resolution sub-frame, and in a second sub-frame time, a second set of sub-pixel halves different from the first set of sub-pixel halves provides a second lower resolution sub-frame, wherein the first and second sub-frames together provide a complete higher spatial resolution frame with the information for enabling its autostereoscopic view, such that the complete spatial frame resolution is built up in a sequence. in a frame time comprising a first and second sub-frame time, the display panel produces a frame of the display output, characterised in that : in a first sub-frame time, a first set of sub-pixel halves provides a first lower resolution sub-frame, and in a second sub-frame time, a second set of sub-pixel halves different from the first set of sub-pixel halves provides a second lower resolution sub-frame, in a first sub-frame time, a first set of sub-pixel halves provides a first lower resolution sub-frame, and in a second sub-frame time, a second set of sub-pixel halves different from the first set of sub-pixel halves provides a second lower resolution sub-frame, wherein the first and second sub-frames together provide a complete higher spatial resolution frame with the information for enabling its autostereoscopic view, such that the complete spatial frame resolution is built up in a sequence. <EOS>
