Abstract
A self-scanning, light-emitting device comprises an array of cells or blocks each having a self-scanning transfer element and a light-emitting element. Turn-on state of the transfer element is transferred to the subsequent transfer element in synchronism with clock pulses. Each light-emitting element is connected to the corresponding transfer element so as to emit light upon supplying current under an ON state of the transfer element. The light-emitting array generates a light image in accordance with a light emission current.
