More Information
Summary:The invention provides a driving method of a display device. The display device comprises a display panel and a touch panel. The driving method comprises the following steps: providing a line synchronization signal for a plurality of scanning lines of the display panel; providing a touch control driving signal for a plurality of touch control driving signal lines of the touch panel, wherein at least within a preset time interval, the orthographic projections of the scanning lines receiving the line synchronization signal on the display panel are not coincided with the orthographic projections of the touch control driving signal lines receiving the touch control driving signal on the display panel. The invention further provides the display device. When the display device displays a picture within the preset time interval, the scanning lines receiving the line synchronization signal are staggered away from the touch control driving signal lines receiving the touch control driving signal, and capacitive coupling is hardly generated between the scanning lines receiving the line synchronization signal and the touch control driving signal lines receiving the touch control driving signal, so that the signal to noise ratio of the touch panel within a preset moment is increased.
