    摘要: A shift register includes a plurality of stages of unit circuits each including a flip-flop. Each of the unit circuits generates, by obtaining a sync signal in accordance with an output from the flip-flop, an output signal. The flip-flop includes a first switch and a second switch and a latch circuit for latching a signal supplied thereto and outputting the signal as the output from the flip-flop. A first shift direction signal is supplied to the latch circuit via the first switch, and the second shift direction signal is supplied to the latch circuit via the second switch. In each unit circuit other than those of the first and last stages, an output signal from a previous stage is supplied to a control terminal of the first switch, and an output signal from a subsequent stage is supplied to a control terminal of the second switch.

    摘要: A memory-type liquid crystal display device includes a liquid crystal panel including memory circuits, and conducts a refresh operation more than once during a display holding period after rewriting of a screen. The memory-type liquid crystal display device increases at least one of (i) a frequency at which the screen is rewritten and (ii) a frequency at which the refresh operation is conducted during the display holding period as an intensity of light received by the liquid crystal panel increases. This allows the memory-type liquid crystal display device to reduce power consumption while keeping its display quality.

    摘要: An object of the present invention is to provide a power supply circuit including a charge-pumping booster section which uses switching elements provided only by N-channel transistors yet does not have a problem of voltage drop by threshold value. In a booster section (11a), capacitors (C1) and (C2) have their respective first terminals connected with transistors (Q1, Q3) and (Q2, Q4) respectively. Each transistor has its gate terminal supplied with control signals generated in a driver section (11b). The driver section (11b) includes capacitors (C3, C4) connected with input terminals (Ti3, Ti4) for respective supply of clock signals DCK2, DCK2B each having a voltage alternating between −VDD and VDD (VDD represents an input supply voltage from outside), as level-shifted signals of clock signals DCK1, DCK1B which are supplied to second terminals of the capacitors (C1, C2) respectively. In this arrangement, the driver section 11b generates signals each having a voltage alternating between VDD and 3VDD, as the control signals.

    摘要: In one embodiment of the present invention, a unit circuit of a shift register includes a bootstrap circuit configured with a transistor T1, a transistor T2 and a capacitor, a transistor T3, a transistor T4, and a reset signal generation circuit. By use of two-phase clock signals and whose high level periods do not overlap with each other, the reset signal generation circuit generates a reset signal which is at a high level in a normal state and changes to a low level when an input signal turns into the high level. During a period that the reset signal is at the high level, transistors T3 and T4 perform discharge of a node and pull-down of an output signal. Thus, it is possible to obtain a power-saving shift register that fixes an output signal at a low level in a normal state without allowing a through current to flow therein.
