Abstract
A method for correcting non-uniformities of one or more display panels of a HMD (e.g., a VR headset or an AR headset) is disclosed, where the method is based on a luminance level of content being displayed. The method includes obtaining the calibration data for correcting non-uniformity of a display panel of the HMD at various brightness levels and storing the data. In response to receiving a request for providing content to be presented on the HMD, the host applies the calibration data based on a luminance level of content being rendered to correct for any non-uniformities of the one or more display panels while rendering the content for display.
