Abstract
The disclosed computer-implemented method may include a display calibration apparatus. The display calibration apparatus may include a lens and an actively-cooled electromagnetic radiation detector configured to detect electromagnetic radiation emitted from various pixels of an electronic display panel under test. The electromagnetic radiation may travel through the lens prior to reaching the detector. The display calibration apparatus may also include a special-purpose computing device configured to: analyze the detected electromagnetic radiation from the pixels of the electronic display panel and generate calibration data for the electronic display panel using a specified calibration algorithm. As such, the electronic display panel may operate using the generated calibration data. Various other methods, systems, and computer-readable media are also disclosed.
