Variable-resolution displays

Abstract

A variable-resolution display comprises a display substrate and pixels disposed on the display substrate. Adjacent pixels are arranged over the display substrate with different spatial separations and at different spatial resolutions in one or two dimensions so that some portions of the display substrate have a greater spatial density of pixels and other portions of the display substrate have a lesser spatial density of pixels. The pixels are controlled to emit light in response to an unchanging image frame comprising image data for each pixel during a temporal frame period. An optical communication system comprises a variable-resolution display and a camera system comprising a digital camera, a memory, and a processor. The digital camera is disposed relative to the variable-resolution display such that the digital camera is operable to record an image displayed on the variable-resolution display and the processor is operable to process the recorded image.
