摘要： At least one embodiment the present invention a plurality of unit circuits connected in multiple stages, to normal operation when the unit circuits are simultaneously turned on to output high-level output signals. When a shift register malfunctions, so that output signals provided by previous- and subsequent-stage unit circuits are simultaneously set to high level, malfunction restoration circuits and included in a unit circuit detect the malfunction in at least one embodiment. The malfunction restoration circuit provides a high voltage to a node, thereby forcibly pulling down an output signal. Also, the malfunction restoration circuit forcibly discharges another node, so that a charge accumulated in a capacitance is released. As a result, the shift register in malfunction can be instantaneously restored to normal operation. At least one embodiment of the present invention is suitable for driver circuits or suchlike of display devices and imaging devices.

摘要： In one embodiment of the present invention, a unit circuit of a shift register includes a bootstrap circuit configured with a transistor T1, a transistor T2 and a capacitor, a transistor T3, a transistor T4, and a reset signal generation circuit. By use of two-phase clock signals and whose high level periods do not overlap with each other, the reset signal generation circuit generates a reset signal which is at a high level in a normal state and changes to a low level when an input signal turns into the high level. During a period that the reset signal is at the high level, transistors T3 and T4 perform discharge of a node and pull-down of an output signal. Thus, it is possible to obtain a power-saving shift register that fixes an output signal at a low level in a normal state without allowing a through current to flow therein.

摘要： Provided is a shift register of a display-driving circuit which carries out simultaneous selection of a plurality of signal lines by using a simultaneous selection signal. A stage of the shift register includes (i) a set-reset type flip-flop and (ii) a signal generating circuit which generates an output signal of the stage by selectively outputting a signal in response to an output of the flip-flop. The output signal of the stage (i) becomes active due to an activation of the simultaneous selection signal and then (ii) remains active while the simultaneous selection is being performed, and the output from the flip-flop is inactive during a period in which a setting signal and a resetting signal are both being active. This makes it possible to quickly carry out the simultaneous selection of all the signal lines and the initialization of the shift register.
