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： A stage of the shift register has (i) a set-reset type flip-flop which receives an initialization signal and (ii) a signal generating circuit which receives a simultaneous selection signal and which generates an output signal by use of an output of the flip-flop. In at least one example embodiment, the output of the flip-flop becomes inactive regardless of whether a setting signal and a resetting signal are active or inactive, as long as the initialization signal is active. The initialization signal becomes active before the end of the simultaneous selection, and then becomes inactive after the end of the simultaneous selection. This makes it possible to stabilize operation of the shift register after the end of simultaneous selection of a plurality of signal lines carried out by the display driving circuit at a predetermined timing.

摘要： At least one embodiment of the present invention is directed to, even when external noise is applied to a shift register during all-on operation, preventing through-current from flowing in unit circuits and also to prevent increase in load on all-on control signal lines. When a high-level all-on control signal is provided to a unit circuit of a shift register, a transistor T3 is brought into off-state, so that a transistor T2 cannot output an on-voltage to a first output terminal. However, a transistor T24 is brought into on-state, so that the first output terminal outputs an on-voltage to the exterior. On the other hand, a transistor T32 is brought into on-state, so that a second output terminal outputs an off-voltage to a unit circuit 11 in the next stage. At this time, the transistor T3 is kept in off-state, so that no through-current flows to the transistors T24 and T3.
