    摘要: An output pulse of a flip flop is delayed in a delay inverter circuit before supplied to an input terminal of a level shifter. Then, an output pulse of the next stage flip flop is supplied to a reset terminal of the first flip flop and also to an enable terminal of the level shifter. Further, the level shifter output a sampling pulse with a beginning end equal to the beginning end of the pulse supplied to the input terminal and a terminal and equal to the beginning and of the pulse supplied to the enable terminal. With this arrangement, the subject invention provides a pulse output circuit, a driving circuit for a display device using the pulse output circuit, a display device and a pulse output method, that reduce delay of the terminal end of the pulse in sequentially outputting pulses from plural output terminals.

    摘要: In each horizontal period, by switching ON switches respectively provided for three data signal lines for R, G and B in a group at the same time only in a predetermined period, the data signal lines in the group are preliminary charged to a predetermined potential at the same time before a data signal supply period. In a subsequent data signal supply period, respective switches of data signal lines for R, G and B are switched ON sequentially, to sequentially supply respective data for R, G and B to pixels on a scanning signal line as selected are supplied via data signal lines. As a result, in a display device driven by time-division based on a group of sequentially provided data signal lines, it is possible to suppress up-throw potential fluctuations when display.

    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 a shift register of the present invention, each of flip-flops has a phase difference detection section and a waveform timing forming section as a malfunction prevention circuit. The phase difference detection section detects an overlapping waveform caused by a phase difference between clock signals SCK and SCKB, and generates an output signal A (A1, A2, . . . ) from which the overlapping portions are removed. The waveform timing forming section outputs an output signal X (X1, X2, . . . ) obtained by extracting a period when the output signal A (A1, A2, . . . ) generated in a corresponding phase difference detection section is High, when an output signal Q (Q1, Q2, . . . ) from a corresponding flip-flop is High. The output signal X (X1, X2, . . . ) sets a flip-flop in a following stage. According to the above arrangement, it is possible to realize a shift register which does not malfunction and functions properly even in cases where two clock signals SCK and SCKB inputted to the shift register and having different phases from each other are out of phase. It is also possible to realize a display device having the shift register.
