Embodiment Construction

[0058] In order to illustrate the present invention more clearly, the liquid crystal display panel is taken as an example in the following embodiments. Those skilled in the art can follow the spirit of the present invention and the illustrations of the embodiments, and deduce it to various display panels, all of which are within the scope of the present invention.

[0059] FIG. 7A is a circuit block diagram of a liquid crystal display panel driving device capable of reducing crosstalk according to the first embodiment of the present invention. Please refer to FIG. 7A , the liquid crystal display panel driving device includes source driver integrated circuits 701 - 708 , an inverter 710 , a timing controller 720 and a liquid crystal display panel 730 . The timing controller 720 sequentially transmits multiple pieces of pixel data D to the source driver integrated circuits 701 - 708 . The timing controller 720 also outputs a polarity control signal POL, and each source driver i...

Abstract

A display face plate driving method enabling to decrease crosstalk includes using time sequence controller to provide polarity control signal to be used on partial source electrode driving unit and then providing reversed phase of polarity to the other source electrode driving unit. The driving device used for realizing said method is also disclosed.

Description

technical field [0001] The present invention relates to a device and method for driving a display panel, in particular to a display panel driving device and method capable of reducing crosstalk. Background technique [0002] In order to enhance the display quality of the display panel, the polarity of the driving signal of the display panel is usually inverted. For example, the display panel of a thin film transistor liquid crystal display (TFT-LCD) uses liquid crystal as the material to control the display. In order to avoid the polarization of the liquid crystal, it needs to be driven in an AC mode. Inversion), column inversion (ColumnInversion) and other polarity inversion driving methods. [0003] Figure 1 illustrates the driving architecture of a general liquid crystal display. Referring to FIG. 1 , the source driver 110 and the gate driver 120 respectively output a plurality of pixel driving signals and scanning signals to corresponding data lines and scanning lines ...
