Apparatus for driving liquid crystal display panel, liquid crystal display apparatus, electronic apparatus, and method of driving liquid crystal display panel

Abstract

The invention prevents crosstalk of preceding data and to improve contrast in a liquid crystal display panel using a two-terminal type non-linear element such as a MIM element even when a charge and discharge drive method is used as a method of driving the liquid crystal display panel. A scanning signal is formed of a signal in a charging mode and a signal a discharging mode. A charging period in which the voltage value of a first selecting voltage in the charging mode is applied is set as a predetermined period in a first horizontal period. An overcharging period in which the voltage value of a precharge voltage in the discharging mode is applied is set as the first half of a second horizontal period vertical period after the first horizontal period, and a discharging period in which a second selecting voltage is applied is set as the second half of the second horizontal period. A data signal in the charging mode is supplied in the predetermined period (charging period) in the above-mentioned first horizontal scanning period while a data signal in the discharging mode is supplied both in the first half and in the second half of the second horizontal period (overcharging period and discharging period) without changing its polarity.
