    摘要: A self-scanning light-emitting device is provided in which the amounts of light of light-emitting elements may be corrected to make the distribution of amounts of light in a luminescent chip or among luminescent chips uniform. The correction for amounts of light of light-emitting elements may be carried out by regulating the time duration of on-state of a light-emitting element or the voltage of a write signal applied to a light-emitting element. According to the present invention, the distribution of amounts of light becomes uniform, so that the printing quality of a printer using such self-scanning light-emitting device is improved.
