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： 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： 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.
