Abstract
A luminance compensation method of a light-emitting device is disclosed. The light-emitting device has a plurality of light-emitting elements. The luminance compensation method includes following steps of: obtaining a position of at least one of the light-emitting elements in a brightness anomalous status; and changing a brightness of at least one of the light-emitting elements disposed adjacent to the light-emitting element in the brightness anomalous status for compensating a brightness of the light-emitting elements in the brightness anomalous status.
