摘要： A driver device scans and drives light emission elements arranged in a branch connection to a common terminal using scan-circuit and data drive portions and clock driver and waveform shaper circuits. The scan circuit portion has scan circuits connected cascadely to one another with output terminals connected to the light emission elements. The driver device outputs first and second clock signals to odd- and even-numbered scan circuits respectively. The light emission elements are sequentially driven from a first to a last scan circuit when the second-clock signal is applied to the first scan circuit. The data-drive portion drives the common terminal. The clock-driver circuit outputs first and second clock pulses with different phases, and a third-clock pulse synchronized with the first and second clock pulses. The waveform-shaper circuit re-shapes the waveforms of the clock signals.

摘要： A driver apparatus drives a plurality of light emitting thyristors. Each thyristor includes a cathode connected to the ground, an anode, and a gate. A gate driver circuit outputs a drive signal that electrically drives the gate. A level shifter circuit includes an input terminal connected to the driver circuit and an output terminal connected to the gate of the thyristor. The level shifter circuit operates such that the drive signal is shifted down in signal level and is outputted to the output terminal and a signal at the gate inputted to the output terminal is shifted down in signal level and is outputted to the input terminal. In response to the drive signal outputted from the driver circuit, a current supplying circuit supplies drive current to the anode of the thyristor such that the drive current flows from the anode to the cathode.

摘要： A combined semiconductor device can be formed by bonding the thin-film three-terminal switching elements to a surface of an integrated circuit chip including a shift register that shifts data supplied to the control electrodes of the three-terminal switching elements, or by bonding both the thin-film three-terminal switching elements and another thin semiconductor film including the shift register to a substrate. In either case, thin-film wiring can be used to interconnect the shift register and the switching elements, and the need for an array of large transistors to feed driving current to the switching elements is eliminated, reducing the size and cost of the combined semiconductor device, which can be advantageously used in the optical head of an electrophotographic printer.
