LCD AND DRIVING METHOD THEREOF

摘要

PURPOSE: An LCD and a driving method thereof are provided to remove an afterimage by setting properly a relation between an optimum common voltage of a white gray scale and an optimum common voltage of a black gray scale. CONSTITUTION: An LCD includes an LCD panel(1), a gate driving portion(2), and a data driving portion(3). The LCD panel(1) is formed with a plurality of gate lines, a plurality of data lines, a plurality of TFTs having gate electrodes connected to the gate lines and source electrodes connected to the data lines, the first substrate including pixel electrodes, and the second substrate including common electrodes. The gate driving portion(2) applies the gate voltage to the gate lines in order to turn on/off the TFTs. The data driving portion(3) applies the gray voltage to the data lines. The LCD satisfies a condition such as optimum common voltage of white gray scale-optimum common voltage of a black gray scale<= setup value.
