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： 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.

摘要： A driving device for a display apparatus having excellent contrast and a high display quality without crosstalk and display irregularities, and a driving method for the same are provided. In the driving device, scanning signals and data signals having a plurality of periodical inactive portions in one frame are applied to respective display dots. In the inactive term, a fixed voltage is applied to each of the display dots. The signal applied to the display dot is divided into small terms by the inactive portions, resulting in more high frequency components in a voltage signal applied to the display dot. As a result, the frequency components of a driving signal applied to the display dot are averaged. Further, a complete orthogonal function having 2.sup.r base function series is used, and a desired display data is completely reproduced on the display apparatus by an arithmetic process assuming auxiliary data in accordance with the number of the scanning electrodes.
