Abstract:
A display panel is initialized to a native state where no color corrections are applied. A native response of the display panel is measured in the native state. One or more calibration operations for the display panel are performed based on the measured native response and calibration data is generated. The generated calibration data is stored in a timing controller (TCON) chip of the display panel. One or more chromaticity values of the display panel are measured while driving the display panel in a calibrated state based on the generated calibration data. The measured chromaticity value of the display panel is stored as Extended Display Identification Data (EDID) or DisplayID data in the TCON.
