    摘要: A shift register includes control circuits CNi (i=1 through n) corresponding to respective blocks, and a level shifter LSi+1 of the next stage is controlled by one of the outputs of the shift register and one of the outputs of flip-flops Fi. With this, a level shifter of the present stage operates only for a period minimum for outputting the shift output from the present block, so that the power consumption is reduced, Furthermore, it is possible to cause the outputs SL1 through SLn not to overlap each other.

    摘要: A level shift circuit includes first and second level shifters which respectively output first and second output signals that are produced by level shifting two kinds of input clock signals whose high level periods do not overlap. The level shift circuit also includes control transistors and control lines which, together, prevent a feedthrough current from flowing into the second level shifter when the first output signal is high level, and prevent a feedthrough current from flowing into the first level shifter when the second output signal is high level, so as to suspend the level shift operation of the first and second level shifters. With the level shift circuit, power consumption during a specific time period in a non-active period of the clock signal can be eliminated, where the specific time period of one clock signal is the active period of the other clock signal.

    摘要: A shift register includes plural stages of flip-flops. The last-stage flip-flop Fn and the flip-flop Fn−1 that is the preceding flip-flop thereof are reset by inputting thereto an output signal from the last-stage flip-flop. A delaying means is provided, between an output terminal Q of the last-stage flip-flop for outputting the output signal and an input terminal R of the last-stage flip-flop for receiving the output signal, for delaying an input of the output signal to the input terminal R. The flip-flop Fn is reset at same time or after the preceding flip-flop Fn−1 is reset. With this arrangement, it is possible to prevent malfunctions of circuits due to a failure to reset the flip-flops.

    摘要: In one embodiment of the present invention, a NAND circuit, an inverter, a plurality of transistors serve as stopping devices for stopping operation of a circuit in a manner responsive to a level of an initializing signal that is fed. If the initializing signal that is Low-level is fed into the NAND circuit, then a plurality of transistors all become OFF. This makes it possible to reduce steady current flowing across a voltage and a start signal. Steady current flowing across the voltage and a start inverted signal is also reduced. Thus, the steady current flowing through the level shifter is reduced reliably, regardless of the way of use, when necessary.

    摘要: The subject invention discloses a scanning direction control circuit, which includes a bidirectional shift register in which shifting direction is switched in accordance with a switching signal L/R, which is step-upped by a level shifter when having lower amplitude than the driving voltage. The scanning direction control circuit includes a latch circuit between the level shifter and the bidirectional shift register, and a control circuit causes the latch circuit to carry out latching operation after shifting operation of flip-flops constituting the bidirectional shift register is completed in response to output signals of the flip-flops. The control circuit brings the level shifter into active state in a period before, at and after the latching timing, and brings the level shifter into inactive state in the remaining period. With this arrangement, the switching signal L/R can be supplied at a predetermined timing regardless of external input timing thereof, with low power consumption.
