Method for compensating and checking light amount of light-emitting device

摘要

A method for compensating and checking a light amount is applicable to a light-emitting device including a plurality of light-emitting elements, and the following steps are successively executed on the light-emitting elements: measuring an original light amount output by a light-emitting element within a reference time interval; generating a calibration value corresponding to the light-emitting element according to the measured original light amount and a reference light amount; and adjusting light output of the light-emitting element according to the calibration value, so that the original light amount reaches a target light amount.

1. A method for compensating and checking a light amount of a light-emitting device, wherein the light-emitting device comprises a plurality of light-emitting elements, and the method for compensating and checking a light amount comprises:
successively testing each of the light-emitting elements by performing the following steps thereon:
measuring an original light amount output by the light-emitting element within a reference time interval;generating a calibration value corresponding to the light-emitting element according to the measured original light amount and a reference light amount, wherein the calibration value is a lighted duration of the light-emitting element; andadjusting a light output of the light-emitting element according to the calibration value, so that the original light amount reaches a target light amount.
