Abstract: A data driver includes shift registers, sampling latches, holding latches, and a data sensing unit. The shift registers generate sampling pulses by shifting a source start pulse in response to a source sampling clock. Each of the sampling latches receives current data and stores the current data in response to each of the sampling pulses. Each of the holding latches receives the current data stored in each of the sampling latches, and stores the received current data in response to a source output enable signal. The data sensing unit receives the current data corresponding to an i-th sampling latch of the sampling latches or an i-th holding latch of the holding latches (i is a positive integer) and previous data stored in the i-th sampling latch or the i-th holding latch, compares the current data with the previous data, and generates control data based on the comparison result.

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.
