Abstract
A display apparatus is provided. The display apparatus includes: a display panel, a non-volatile memory, and a controller. The controller is configured to adjust first gain values of the display panel, and obtain two-dimensional color coordinates in a first predetermined color space of the white screen displayed by the display apparatus as white-color coordinates. The controller further adjusts colors displayed by the display apparatus to fit a second predetermined color space, calculates second gain values in the second predetermined color space according to the white-color coordinates, and stores the second gain values in a color-calibration setting in a non-volatile memory of the display apparatus. In response to a selection signal from the display apparatus, the controller reads the color-calibration setting corresponding to the selection signal from the non-volatile memory for execution to perform color calibration on the display apparatus.
