摘要： In a shift register, which is for use in an image display apparatus of the TFT active matrix type in which a driver circuit is integrally provided on a display panel, and which is so arranged as to boost a start pulse SP to a start pulse SPO by using a level shifter, and to supply the start pulse SPO to a flip-flop F1 of a shift register section, the start pulse SP having an amplitude lower than a driving voltage and being supplied thereto, the shift register is provided with an operation control circuit for inactivating the level shifter when the first stage flip-flop F1 outputs an output signal S1 and activates the level shifter when a last stage flip-flop Fn outputs an output signal Sn. Therefore, it is possible to reduce power consumption of the level shifter during a period in which the start pulse SPO is transmitted from a flip-flop F2 to a flip-flop Fn−1.

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 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： An example 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. In other words, the pixels in the display area are refreshed at intervals longer than those in the case of refreshing the pixels in each frame. Thus, even if the mobility of an active element is high and the leak current on the occasion of OFF-state is large, or even if a large amount of electric charge is accumulated because of the photoelectric effect due to the use of a backlight, it is possible to prevent unnecessary displaying on the display area, which is caused because the writing into the pixels in the display area influences on the pixels in the non-display area, and hence it is possible to improve the quality of partial displaying, while restraining the power consumption.

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.
