METHOD AND APPARATUS FOR DISPLAY CALIBRATION

摘要

A calibration system can be provided to calibrate displays in electronic devices during manufacturing. The calibration system can include calibration computing equipment and a test chamber with an optical sensor. The calibration computing equipment can be configured to operate the display and the optical sensor in order to collect display intensity performance data for obtaining a display gamma model. The display intensity performance data can be collected by using a range of display control settings which are to be used when performing color calibration operations for the display. The calibration computing equipment can be configured to operate the optical sensor and the display in order to collect display color performance data for determining display white point calibration. Display white point calibration data can be provided for an electronic device and stored in a volatile or non-volatile memory in the device, or can be permanently stored in circuitry associated with the display.
