  • Publication number: 20120113084
    Abstract: A liquid crystal display (LCD) and a driving method thereof are disclosed. According to some aspects the liquid crystal display (LCD) includes: a display unit including a plurality of pixels arranged in a matrix, a gate line respectively connected to the plurality of pixel rows, and a data line respectively connected to a plurality of pixel columns. The LCD further includes a gate driver configured to generate and sequentially transmit a plurality of gate signals to a plurality of pixel rows through the gate line by row to turn on a switch included in the pixel. The LCD further includes a data driver configured to apply a data voltage according to an image data signal to the pixel during a period in which the switch is turned on; and a common voltage generator configured to generate and apply a common voltage having a polarity that is opposite to the polarity of the data voltage to the pixel.

  • Patent number: 7855722
    Abstract: A Liquid Crystal Display (LCD) includes: a liquid crystal panel having liquid crystal cells divided by scan lines and data lines and arranged in a matrix shape; a data driving circuit to supply an image signal to the liquid crystal cells via the data lines; a scan driving circuit to sequentially select and scan the scan lines and to control an on/off state of switching elements arranged in each of the liquid crystal cells; a timing controller to drive both the data driving circuit and the scan driving circuit, based on an externally inputted signal; and a common electrode driving circuit to drive a common electrode of the liquid crystal panel. The common electrode driving circuit supplies a common voltage to the common electrode, the common voltage including a DC voltage for a first period of a first horizontal period (1H) and another voltage for a second remaining period of the first horizontal period (1H).
