Problems solved by technology
[0003] In practical applications, due to the short distance between the data lines in the panel, when the voltage of the data lines changes, the phenomenon of cross talk will be caused due to the difference in the number of conversions of the driving voltage.
In addition, due to the capacitive charging effect, when the number of voltage polarity changes of adjacent data lines is different, it will also cause crosstalk.

Embodiment Construction
[0028] Please refer to figure 1 , figure 1 It is a schematic diagram of a display device 10 in an embodiment of the present invention. The display device 10 can be an electronic device with a display panel such as a smart mobile phone, a tablet computer, a notebook computer, etc., and its detailed composition or structure varies depending on different applications. For simplicity, figure 1 Only a panel 100 and a driving module 102 of the display device 10 are shown, and other elements not directly related to the concept of the present invention, such as a casing and a connection interface, are omitted. Such as figure 1 As shown, the panel 100 includes scan lines SL1˜SLn and data lines DL1˜DLm. Wherein, each junction of the scan lines SL1 ˜SLn and the data lines DL1 ˜DLm is respectively coupled to the pixels PIX_1_1 ˜PIX_m_n. The operating principle of the panel 100 should be well known to those skilled in the art, and for the sake of brevity, details are not described her...

The invention discloses a driving module and a driving method thereof. The driving module comprises a column driving unit which is used for generating a plurality of column driving signals of a plurality of scanning lines in a driving panel, wherein in the first frame, the second frame, the third frame and the fourth frame, a first column driving signal, a second column driving signal, a third column driving signal and a fourth column driving signal in a plurality of column driving signals simultaneously drive a first scanning line, a second scanning line, a third scanning line and a fourth scanning line in a plurality of scanning lines. Furthermore the column driving unit is used for adjusting the first column driving signal, the second column driving signal, the third column driving signal and the fourth column driving signal so that the numbers of voltage polarity switching times of the first column driving signal, the second column driving signal, the third column driving signal and the fourth column driving signal in the first frame, the second frame, the third frame and the fourth frame are same.
Description
technical field [0001] The present invention relates to a driving module and a driving method thereof, in particular to a driving module capable of reducing crosstalk (CrossTalk) and a driving method thereof. Background technique [0002] Liquid Crystal Display (LCD) has the advantages of thin and light appearance, low radiation, small size and low energy consumption, etc., and is widely used in electronic products such as computer notebook computers or flat-screen TVs. Therefore, the liquid crystal display has gradually replaced the traditional cathode ray tube display (Cathode Ray Tube Display) to become the mainstream of the market, among which the thin film transistor liquid crystal display (TFT LCD) is the most popular. In simple terms, the driving system of the thin film transistor liquid crystal display is composed of a timing controller (Timing Controller), a source driver (Source Driver) and a gate driver (Gate Driver). The source driver and the gate driver respect...
