The present invention relates to a display device, and more particularly, to a display device and a driving method thereof.

In a conventional display panel, in order to save power consumption, the display device usually drives the display panel through a column inversion driving method. However, at this time, all the pixels of each odd-numbered row (Row) in the display panel are of a certain polarity, and all the pixels of each even-numbered row are of another polarity (for example, all the pixels of the odd-numbered row are positive poles). All pixels in the even-numbered rows are negative polarity), which makes the display screen easy to cause the phenomenon of shaking head pattern.

On the other hand, for all pixels on each column of the display panel, when it happens that the number of all positive-polarity pixels on each column is not the same as the number of negative-polarity pixels (that is, on each column When the polarities of all the pixels are unbalanced), the display screen is prone to crosstalk. In this case, the pixel quality of the display panel will be degraded. Therefore, it will be an important issue for those skilled in the art how to reduce the wobble and crosstalk while saving the power of the display panel and effectively improve the image quality of the display panel to improve the viewing quality of the display image.

The present invention provides a display device and a driving method thereof, which can effectively improve the wobble pattern and crosstalk phenomenon of a display panel, thereby improving the quality of a display image.

The display panel has a plurality of sub-pixels, and the plurality of sub-pixels are arranged into a plurality of display columns and a plurality of sub-pixel rows. The gate driver is coupled to the display panel and provides a plurality of gate driving signals to drive the plurality of display columns respectively. The source driver is coupled to the display panel and provides a plurality of source driving signals to write a plurality of gray-scale voltages to the plurality of sub-pixels respectively. The number of all sub-pixels with the first polarity on each display column is the same as the number of sub-pixels with the second polarity, and the polarities of all sub-pixels on each sub-pixel row are not exactly the same, where the first polarity different from the second polarity.

The driving method of the display device of the present invention includes: providing a display panel with a plurality of sub-pixels, arranging the plurality of sub-pixels into a plurality of display columns and a plurality of sub-pixel rows; making the gate driver provide a plurality of gate driving signals to Drive a plurality of display columns respectively; make the source driver provide a plurality of source driving signals to write a plurality of gray-scale voltages to a plurality of sub-pixels respectively; make the number of all the sub-pixels with the first polarity on each display column equal to The number of sub-pixels of the second polarity is the same; and the polarities of all sub-pixels on each sub-pixel row are not identical, wherein the first polarity is different from the second polarity.

Based on the above, the display device and the driving method thereof according to the embodiments of the present invention can make the number of all positive-polarity sub-pixels and negative-polarity sub-pixels on each display column in the display panel the same, and make each The polarities of all sub-pixels on a sub-pixel row are not identical.
