Abstract: The present disclosure provides a display correction method and a display correction system. The method is used by the display correction system to correct display performance of a display, wherein the display correction system includes an automatic adjustment apparatus and a light detection apparatus. The method includes: acquiring, by the light detection apparatus, an optical signal emitted by the display, determining a first brightness value according to the optical signal, and transmitting the first brightness value to the automatic adjustment apparatus; in response to determining that the first brightness value is different from a first standard brightness value preset for the display, adjusting, by the automatic adjustment apparatus, the brightness value of the display to the first standard brightness value; and triggering, by the automatic adjustment apparatus, a brightness sensor in the display to detect brightness of the display, and in response to determining that a second brightness value detected by the brightness sensor is different from a second standard brightness value preset for the brightness sensor, correcting the second standard brightness value of the brightness sensor to the second brightness value.
