Abstract:
A method for driving a self-scanning light-emitting element array including 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 electrodes of each of the transfer elements; and a light-emitting element array having such a structure that a plurality of three-terminal light-emitting elements having a control electrode for controlling threshold voltage or current are arranged, the control electrodes of the light-emitting element are correspondingly connected to the control electrodes of the transfer elements, and a write signal line connected to one of two terminals other than the control electrode of each of the light-emitting elements is provided;the method comprising a step of causing the difference between Low-level and High-level of a pulse voltage for a write signal supplied to the write signal line through a current limiting resistor smaller than the difference between Low-level and High-level of a pulse voltage for transfer also supplied to the clock lines, so as to decrease a power consumed by the current limiting resistor.
