Abstract
The present disclosure provides a display device, a driving method and a driving system thereof. The driving method includes steps of: detecting whether a polarity of a scan signal inputted from current scan line is reversed; when the polarity of the scan signal inputted from current scan line is reversed, a time period of charging the current scan line is extended. By extending the time period of charging the scan line when the polarity of the scan signal on the scan line is reversed, the sub-pixels on the scan line can be charged normally for normal display. As a result, the defect of undesired bright and dark stripes or grid effect shown on a display device can be eliminated effectively.
Claims13
A driving method of a display device, wherein the display device comprises a plurality of scan lines, and each of the plurality of scan lines is electrically connected to a column of sub-pixels corresponding thereto, and the method comprises:
- detecting whether a polarity of a scan signal inputted from current scan line is reversed;
- and
- extending a time period of charging the current scan line when the polarity of the scan signal inputted from the current scan line is reversed.
A driving system of a display device, wherein the display device comprises a plurality of scan lines, and each of the plurality of scan lines is electrically connected to a row of sub-pixels, and the driving system comprises:
- a polarity detection unit configured to detect whether a polarity of a scan signal inputted from current scan line is reversed;
- a time extending unit configured to extend a time period of charging the current scan line when the polarity of the scan signal inputted from the current scan line is reversed.
A driving method of a display device, wherein the display device comprises a plurality of scan lines and a gate drive module, and each of the plurality of scan lines is electrically connected to a row of sub-pixels corresponding thereto, and the gate drive module is electrically connected to the plurality of scan lines, and the driving method comprises:
- comparing whether a polarity of a scan signal inputted from last scan line is equal to a polarity of a scan signal inputted from current scan line;
- determining that the polarity of the scan signal inputted from the current scan line is reversed when the polarity of the scan signal inputted from the last scan line is different from the polarity of the scan signal inputted from the current scan line;
- determining that the polarity of the scan signal inputted from the current scan line is not reversed when the polarity of the scan signal inputted from the last scan line is equal to the polarity of the scan signal inputted from the current scan line;
- and
- when the polarity of the scan signal inputted from the current scan line is reversed, increasing a duty cycle of an enable signal outputted to the gate drive module while the current scan line is charged, so as to extend a time period of charging the current scan line, wherein the enable signal corresponds to the current scan line.
