Abstract: The present disclosure relates to methods and systems for measuring and correcting electronic visual displays. A method in accordance with one embodiment of the present technology includes generating a series of patterns for illuminating proper subsets of the light emitting elements of the display, such as regular grids of nonadjacent activated light emitting elements with the elements in between deactivated. For each generated pattern, an imaging device captures information about the activated light emitting elements. A computing device analyzes the captured information, comparing the output of the activated light emitting elements to target output values, and determines correction factors to calibrate the display to better achieve the target output values. In some embodiments, the correction factors may be uploaded to firmware controlling the display or used to process images to be shown on the display.
