For each of a set of primary color light sources disposed in a unit, measurement points are obtained including chromaticity and luminance values as a function of temperature of the unit and drive currents of the primary color light sources. The measurement points are converted to an XYZ color space to produce XYZ values. For each of a set of target luminances and a set of discrete temperatures, primary luminances are calculated for each of the set of primary color light sources, and the drive currents and the XYZ values are interpolated or extrapolated for each of the primary luminances to obtain calculated currents."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"LED thermal characterization and calibration for an optical display","description":"Techniques are disclosed for calibrating display devices, such as head-mounted augmented reality (AR) devices.
