摘要： A control signal generating circuit CTL for controlling the writing into pixels PIX instructs a data signal line drive circuit SD2, which is for driving pixels in a non-display area, to write a voltage VB or a voltage VW which are for non-displaying, not only in the first frame but also once in a predetermined number of frames.

摘要： A data signal line drive circuit is provided with: a shift register belonging to a system, whose stages correspond to respective sampling units for driving odd-number-th data signal lines; and a shift register belonging to another system, whose stages correspond to respective sampling units for driving even-number-th data signal lines. On the occasion of low-resolution mode, only either of the shift registers is operated, and in accordance with the outputs from the respective stages of the shift register which has been operated, timing signals, which are supplied to the sampling units corresponding to the stages of both shift registers, are generated. With this arrangement, even if one of input signals each having different signal line resolution is inputted, a signal line drive circuit which consumes a small amount of electric power can be realized, while it is possible to specify the timings of the operation of signal line drive sections for driving signal lines, in accordance with the input signal.

摘要： The data signal line driving circuit of the present invention is arranged so that data signal line groups, each of which is made up of two data signal lines sequentially disposed, are connected to two video signal lines, each of which allows a two-phased video signal to be forwarded. A shift register SR, a drive switching circuit, and a waveform shaping circuit, that constitute a video signal fetching section, collect the data signal line groups via the two video signal lines as a single block. At this time, the data signal lines are respectively driven so as to fetch the video signal from the video signal lines into the data signal lines of the data signal line groups in each block. Thus, in performing multiphase development, it is possible to provide the data signal line driving circuit which can reduce power consumption in low resolution driving compared with a case of high resolution driving.

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： 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 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.
