Herein for convenience of understanding, please refer to Fig.4 that (Fig. 4 is the timesharing of preferred embodiment two according to the ... of the embodiment of the present invention
Scan mechanism schematic diagram), as seen in Figure 4, when the first predetermined time interval X (i.e. Delaytime 1 in Fig. 4)
Be ranging from more than 0 and less than or equal to T1, (touch drive circuit scans through the used in first sub-viewing areas
One duration) when, touch-control scan line and driving scan line line between not will produce intersection point, due to point of intersection mean touch-control scanning with
Driving scanning is carried out at the same time, at this time since the Gate lines of driving scanning are opened, the RX (receiving terminal) of the Touch IC of some regions
It is interfered by complete Gate lines are not turned off, noise (i.e. In Cell Noise) is easy tod produce, to influence Touch performances
It uses, and can further influence the accuracy of baseline extractions.
Step S306, it controls second sub-viewing areas of the touch drive circuit pair and carries out touch-control scanning, then control institute
