    摘要： Provided is a display device capable of suppressing reduction in display quality even when pause drive is performed, while allowing the intensity of a light source to be changed in accordance with images to be displayed.
    In a liquid crystal display device with the CABC function, 7. 5-Hz pause drive is performed. A transition period is provided in which images to be displayed are changed gradually from bright image X to dark image Y. In the transition period, the duration of a sub-transition period is five frames. Once the transition period starts, the duration of a vertical display period changes from eight frames to one frame. That is, 7.5-Hz pause drive switches to 60-Hz normal drive. In this manner, the duration of the vertical display period is set to be less than or equal to the duration of the sub-transition period, so that screen refresh is always performed in each sub-transition period of the transition period.

    摘要： A display device where low power consumption is realized without lowering aperture ratio is provided. A liquid crystal capacitive element Clc is sandwiched between a pixel electrode 20 and an opposite electrode 80. The pixel electrode 20, one end of a first switch circuit 22, one end of a second switch circuit 23 and a first terminal of a second transistor T2 form an internal node N1. The other terminals of the first switch circuit 22 and the second switch circuit 23 are connected to a source line SL and a voltage supply line VSL, respectively. The second switch circuit 23 is a series circuit including a transistor T1 and diode D1. A control terminal of the transistor T1, a second terminal of the transistor T2 and one end of a boost capacitive element Cbst form an output node N2. The other end of the boost capacitive element Cbst and the control terminal of the transistor T2 are connected to a boost line BST and a reference line REF, respectively. The diode D1 has a rectifying function from the voltage supply line VSL to the internal node N1.

    摘要： A display circuit for a matrix display includes a plurality of picture elements comprising display elements driven by drive circuits. A data regenerative circuit determines whether an external video signal is to be displayed or whether the image being displayed by the picture elements is to be held. When the image currently stored in the picture elements is to be held, the data regenerative circuit reads the stored image data from a selected picture element, regenerates the level of the data signal and causes this data to be rewritten into the selected picture element.
