Abstract: A driving controller for reducing crosstalk in a display panel device includes a type detection unit and a polarity configuration unit. The type detection unit receives a color domain signal corresponding to one line data of an image so as to decide a data type of the line data. The polarity configuration unit is connected to the type detection unit for producing a polarity configuration corresponding to the data type of the line data based on the data type.
