Abstract
The present invention discloses an in-cell touch screen and a driving method thereof. The method comprises: implementing scan to a display circuit in an active area and implementing scan to a touch control circuit in another active area in the meantime. With the aforementioned way, it can be prevented that the display circuit and the touch control circuit in the same active area are functioning at the same time. Accordingly, the mutual interference between the display circuit and the touch control circuit can be diminished to raise the touch control precision; meanwhile, the scans are implemented at the same time to the different circuits in two active areas and the scan time can be reduced.
