Abstract

In the 2H line inversion driving method among the driving methods of the liquid crystal display device, etc., the time point (T2) indicating that the polarity of the data signal (Dm) is reversed to the time when the first gate selection signal (Gn) is turned off The first period (Wn) of the time interval up to the time point (T3) has the same time length as the second period (Wn+1) indicating the on-period of the second gate selection signal (Gn+1), and will indicate from The period from the time (T3) when the first gate selection signal is turned off to the time (T4) when the data signal (Dm) switches to the data output corresponding to the pixel selected by the second gate selection signal The time interval is set to be equal to or less than the time interval from the time (T5) when the second gate selection signal is turned off to the time (T6) when the polarity of the data signal is reversed. Accordingly, a high-resolution liquid crystal display device and a driving method thereof are provided with suppressed horizontal unevenness.

Description

technical field

[0001] The present invention relates to a driving method for controlling the supply of a selection signal for controlling the conduction of a plurality of switching elements respectively connected to a plurality of pixel electrodes of a liquid crystal display device and a data signal supplied to a plurality of pixels via these switching elements, and having a The driving method is controlled by the control circuit of the liquid crystal display device. Background technique

[0002] In a liquid crystal display device, the gate selection signal output from the gate driver to the gate wiring is slowed down by the wiring resistance of the gate wiring and the stray capacitance of the wiring, and the selection signal is delayed. As a countermeasure, it is well known that the timing at which the gate selection signal changes from on to off (hereinafter referred to as off) or from off to on (hereinafter referred to as on) is the same as that from the source driver to ...
