LIGHT-EMITTING DEVICE

摘要

A self-scanning, light-emitting device consists of a self-scanning switching element array (S(-1), S(0), (S1)) and a light-emitting element array (L(-1), L(0), L(1)). The switching elements (S(-1), S(0), S(1)) are turned on in sequence by means of a self-scanning action controlled by drive pulses ( phi 1, phi 2). Each light-emitting element (L(-1), L(0), L(1)) is connected (G-1,G0, G1) to a respective switching element so as to be turned on when that switching element is scanned. The light-emitting element array (L(-1), L(0), L(1)) generates an image in accordance with a input light emission control current (S in).
