1. A luminance compensation method of a light-emitting device, wherein the light-emitting device comprises a plurality of light-emitting elements, the luminance compensation method comprising steps of:
obtaining a position of at least one of the light-emitting elements [ element ] in a brightness anomalous status [ , among the light-emitting elements] ; 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 element in the brightness anomalous status,
wherein there are N of the light-emitting elements spaced from the light-emitting element in the brightness anomalous status by a first distance, the N light-emitting elements emit light with a [ same ] color the same as the light-emitting element in the brightness anomalous status, [ and ] there are M of the light-emitting elements configured for compensating the light-emitting element in the brightness anomalous status, [ where ] M is less than or equal to N, and M and N are respectively an integer greater than or equal to 1, and
wherein the light-emitting element in the brightness anomalous status has a luminance L1, a difference between the luminance L1 and a normal luminance L is (L1−L), and a luminance of each of the M light-emitting elements configured for compensating the light-emitting element in the brightness anomalous status is between L and (L−(L1−L)).
