Abstract

A display device and a calibration method for the display device are provided. The calibration method includes obtaining calibration coefficients, from which a compressed approximation is determined. The display device obtains the compressed approximation data including basis vectors and reconstruction coefficients, and determines calibration data to at least partially offset a dependence of an optical throughput of the display device on a beam angle and a beam coordinate at the eyebox.
