Abstract:
A self-scanning light-emitting device, comprising:a self-scanning transfer element array having such a structure that a plurality of three-terminal transfer elements each having a control electrode for controlling threshold voltage or current are arranged, the control electrodes of the transfer elements neighbored to each other are connected via first electrical means, a power supply line is connected to the control electrodes via second electrical means, and clock lines are connected to one of two terminals other than the control electrode of each of the transfer elements; a light-emitting element array having such a structure that a plurality of three-terminal light-emitting elements each having a control electrode for controlling threshold voltage or current are arranged, the control electrodes of the light-emitting element array are connected to the control electrodes of the transfer elements, and a line for applying a write signal connected to one of two terminals other than the control electrode of each of the light-emitting elements is provided; and a driver circuit for regulating the time duration of on-state of each of the light-emitting elements to correct amounts of light in every luminescent chip constituting the self-scanning light-emitting device so as to make the distribution of amounts of light among the chips uniform.
