Abstract
A display panel driving device capable of reducing crosstalk and a driving method thereof is disclosed. The display panel driving device includes a plurality of source driving units, a NOT gate and a timing controller. The timing controller, through the NOT gate, provides an inversed-polarity control signal for the source driving units. The display panel driving method includes providing a polarity control signal produced by a timing controller for the remaining source driving units, then inverting the polarity and providing the other partial source driving units with the inversed-polarity control signal. The driving device and the driving method enable the polarities of the pixels on a same horizontal scanning line to be neutral to the greatest extent and avoid crosstalk caused by coupling effect between data lines and the common voltage Vcom. Consequently, the present invention significantly improves the display quality of a display panel by reducing crosstalk.
