Plate, as shown in figure 1, wherein multiplexing public electrode is touch-control driving electrodes, therefore when showing scanning, driving IC is needed to public
Electrode provides the common electrode signal Vcom needed for display;When touch-control is scanned, driving IC needs to provide touch-control to public electrode
Required drive signal, while IC detection touch-control sensing electrodes RX signal is driven, to determine whether touch,
I.e. touch-control scanning refers to inputting scanning signal to touch-control driving electrodes, detects the signal intensity of touch-control sensing electrode.It is preferred that,
Display scanning is performed with touch-control scanning timesharing.In addition, it is generally the case that driven before touch-control scanning is performed or in all touch-controls
Moving electrode is completed after touch-control scanning, and driving IC can perform noise (Noise) scanning, namely not inputted in touch-control driving electrodes
During scanning signal, the signal of touch-control sensing electrode is detected.In the case of touch controllable function is normal, now detect that signal does not change,
