Abstract

The present invention relates to a bidirectional display having a two-dimensional display array comprising a plurality of light-generating pixels and a two-dimensional camera array comprising a plurality of light-detecting elements, wherein the two arrays can each be electrically triggered line by line and are preferably interleaved in at least in some sections, featuring electrical triggering of the display array and of the camera array wherein, during light generation in a line of the display array, light detection with that line of the camera array which is closest to said line is deactivated, i.e. line-sequential electrical triggering of the bidirectional display.
