    Abstract: A liquid crystal display includes: a display panel; a signal controller configured to receive an input image signal and an input control signal, output an output image signal and an output control signal, and determine a charge sharing between two or more data lines having voltages in the same polarity; and a data driver configured to convert, based on the output control signal, the image signal into data voltages to be supplied to the data lines connected to the pixels, the data voltages having positive levels and negative levels. The data driver is further configured to perform a first charge sharing by short-circuiting first and second data lines that are adjacent to each other, and a second charge sharing by short-circuiting third and fourth data lines having data voltages in the same polarity, wherein the first charge sharing and the second charge sharing may not temporally overlap with each other.

    Abstract: A display device may include the following elements: a touch screen unit (or touch-sensing unit) operating with a preset touch driving frequency; a display unit operating with a display driving frequency corresponding to a driving control signal; a noise analyzer determining a frequency band of a panel noise based on a feedback signal provided from the display unit, wherein the panel noise is caused by operation of the display unit; and a driving frequency controller controlling the display driving frequency such that the frequency band of the panel noise avoids the touch driving frequency.
