摘要： In one embodiment of the present invention, the present shift register is a shift register provided in a display device by which a partial-screen display is available. The shift register includes a shift stopping circuit that is provided in an in-between stage, and stops operation of the shift register between a first stage and a last stage of the shift register in partial-screen display. The shift register also includes a circuit that is provided in a stage other than the in-between stage in such a manner that the circuit does not perform signal processing but serves as a signal path. The circuit is same as the shift stopping circuit in configuration. The foregoing allows improvement in display quality of the display device employing the present shift register.

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： 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.

摘要： A driver circuit for a display device includes NOR circuits on the input side of switches for controlling precharge of data signal lines and selected pixels connected to the data signal lines. While a video signal is written onto a data signal line, a signal instructing precharge of another data signal line is inputted from a shift register to the NOR circuits. A simultaneous precharge instruction signal is inputted from outside to the NOR circuits. According to this arrangement, precharge is performed in both a period in which a video signal is supplied to a data signal line and a period in which no video signal is supplied to any of the data signal lines. As a result, it is possible to perform precharge even with a precharge power source having relatively low driving capability, and to precharge the signal supply lines of the display device sufficiently.

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.
