CROSS REFERENCE TO RELEVANT APPLICATIONS

The present disclosure claims the priority of the Chinese patent application filed on Jul. 14, 2020 before the Chinese Patent Office with the application number of 202010675060.9 and the title of “TOUCH-CONTROLLED DISPLAY PANEL AND DRIVING METHOD THEREOF, AND TOUCH-CONTROLLED DISPLAYING DEVICE”, which is incorporated herein in its entirety by reference.

TECHNICAL FIELD

The present disclosure relates to the technical field of touch controlling, and particularly relates to a touch-controlled display panel and a driving method thereof, and a touch-controlled displaying device.

BACKGROUND

In watches, the area of the touch-control region is limited. When selecting or sliding is performed by finger touching, because of the smaller sizes of the icons of the user interface and the bigger finger, in the touch controlling the finger will block the sight line, and the problems of erroneous touching and inaccurate touching easily happen, which results in a poor user experience of touch controlling. In order to solve the problems of erroneous touching and inaccurate touching of the finger, a rotary dial plate may be used to replace the intra-regional finger touch controlling to realize the functions such as slide switching and sliding selection.

Rotary dial plates, as an additional controlling function of touch-controlled watches, are increasingly more popular in watch manufacturers and consumers. Currently, mainly used are mechanical rotary dial plates, in which a rotatable outer dial plate is provided on the watch housing, and the rotation of the dial plate can be sensed and identified by a sensor on the mainboard, to realize the actions such as sliding and interface switching.
