Abstract
A calibration system may be provided for calibrating displays in electronic devices during manufacturing. The calibration system may include calibration computing equipment and a test chamber having a light sensor. The calibration computing equipment may be configured to operate the light sensor and the display to gather display intensity performance data for obtaining a display gamma model. The display intensity performance data may be gathered using a range of display control settings that will be used in performing color calibration operations for the display. The calibration computing equipment may be configured to operate the light sensor and the display to gather display color performance data for determining a display white point calibration. Display white point calibration data may be provided to the electronic device and stored in volatile or non-volatile memory in the device or may be permanently stored in circuitry associated with the display.
