DISPLAY DEVICE, AND CONTROL METHOD FOR DISPLAY DEVICE

摘要

A display device includes a reference storage unit which stores a reference value of color gamut resulting from a reference color sensor measuring primary colors displayed on the screen; a difference calculation part which calculates a difference between the reference value of color gamut stored in the reference value storage unit and the measured value of color gamut resulting from a correcting color sensor measuring primary colors displayed on the screen; and an output part which outputs an alert to notify an abnormality of the correcting color sensor when the difference between the measured value of color gamut and the reference value of color gamut becomes equal to or greater than a predetermined threshold.
