    摘要: An exemplary liquid crystal display device includes a plurality of gate lines configured for providing a plurality of scanning signals, a plurality of data lines configured for providing a plurality of gray scale voltages, and a plurality of pixel units arranged in an array. Each pixel unit includes a first sub-pixel unit and a second sub-pixel unit. The first and second sub-pixel units are connected to one of the gate lines and one of the data lines. A plurality of first common lines are configured for providing a first common signal to the first sub-pixel unit, and a plurality of second common lines are configured for providing a second common signal to the second sub-pixel unit. The first and second common signals are pulse voltage signals and have different starting pulse times according to successive starting pulse times of the scanning signals. An exemplary method for driving the liquid crystal display device is also provided.

    摘要: An exemplary multi-domain vertical alignment liquid crystal display (1) includes a common electrode, a pixel electrode and a liquid crystal layer sandwiched between the common electrode and the pixel electrode. The common electrode, the pixel electrode and the liquid crystal layer are regularly divided into pixel regions. Each pixel region includes a first sub-pixel region (201), a second sub-pixel region (202), a third sub-pixel region (203), and a fourth sub-pixel region (204). Each sub-pixel region includes a protrusion structure (116, 117) at an inner surface of the common electrode. The first sub-pixel region and the third sub-pixel region define a first slit (126) in the pixel electrode, respectively, and have different data voltages applied thereto. The second sub-pixel region and the fourth sub-pixel region define a second slit (127) in the pixel electrode, respectively, and have different data voltages applied thereto.

    摘要: An exemplary liquid crystal display (LCD) (200) includes a first substrate (210); a second substrate (230) opposite to the first substrate; a liquid crystal layer (250) sandwiched between the first substrate and the second substrate; a first common electrode (211), a first insulating layer (212), and pixel electrodes provided at an inner surface of the first substrate in that order; and second common electrodes (231) and floating electrodes (233) provided at the second substrate. The first common electrode and the pixel electrodes, and the second common electrodes and the floating electrodes, respectively produce two electric fields in the liquid crystal layer corresponding to each other. A combined electric field strength is uniformly distributed in the liquid crystal layer, so that all the liquid crystal molecules can be sufficiently twisted. Thus a viewing angle, a degree of chroma, and a transmission ratio of the LCD are improved.
