Abstract: A method of differently producing driving clock signals for a shift register of a gate lines driving circuit of a Liquid Crystal Display (LCD), the method includes the steps of determining whether an ambient temperature is greater than or not in comparison to a predetermined threshold temperature; in response to the determining indicating that the ambient temperature is greater, using a first ON voltage and a first charge canceling method; and in response to the determining indicating that the ambient temperature is not greater, using a second ON voltage and a second charge canceling method, where the second ON voltage is different from the first ON voltage and where the second charge canceling method is different from the first charge canceling method. The second charge canceling method may have a shorter duration than that of the first charge canceling method. The second ON voltage may be greater than the first ON voltage.
