Abstract
Official abstract text for this publication.
A liquid crystal display includes: a liquid crystal display panel including a plurality of data lines and a plurality of gate lines crossing each other; a first source drive IC for outputting a data voltage to the data lines and inverting the polarity of the data voltage in response to a first polarity control signal; a second source drive IC for outputting the data voltage to the data lines and inverting the polarity of the data voltage in response to a second polarity control signal; and a timing controller for generating the first and second polarity control signals in the same phase when the source drive ICs output data voltages whose polarity is inverted by horizontal 1-dot inversion and generating the first and second polarity control signals in the opposite phase to each other when the source drive ICs output data voltages whose polarity is inverted by horizontal 2-dot inversion.
