Abstract
A display device includes a pixel array having a plurality of pixels arranged in a matrix form based on a crossing structure of data lines and gate lines, a data driver having a plurality of output channels and configured to output a data voltage, a multiplexer configured to distribute the data voltage output from the data driver to the data lines in response to first and second control signals, and a gate driver configured to output a gate pulse synchronized with the data voltage in a non-sequential manner. The first and second control signals are in antiphase, and a switching cycle of the first and second control signals is one horizontal period or two horizontal periods.
