1. A method for estimating aging of light emitting elements in a display panel, comprising:
determining a current, a position, and a temperature associated with a light emitting element in the display panel based on display data provided to the display panel at a time interval;
determining a current aging weight of the light emitting element based on the current and a current-aging relationship measured at a standard temperature;
determining a temperature aging weight of the light emitting element based on the temperature and a temperature-aging relationship measured at a standard current;
determining a position aging weight of the light emitting element based on the position;
determining an aging rate of the light emitting element based on the current aging weight, the temperature aging weight, and the position aging weight;
determining an aging time of the light emitting element based on the aging rate of the light emitting element and the time interval; and
determining a luminance loss of the light emitting element based on the aging time and a luminance loss-aging time relationship measured at the standard temperature and the standard current.
