    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.

    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.
