Abstract
The present disclosure provides methods and systems for estimating and compensating the aging of light emitting elements in a display panel. In one example, a method for compensating aging of light emitting elements in a display panel is disclosed. A luminance target is determined based on historical luminance losses of a plurality of light emitting elements in the display panel. An adjusted luminance loss of one of the plurality of light emitting elements is determined based on a current and a luminance loss of the light emitting element. A compensation factor of the light emitting element is determined based on the adjusted luminance loss of the light emitting element and the luminance target. A compensated current is provided to the light emitting element based on the current and the compensation factor of the light emitting element.
