Abstract

The embodiment of the invention discloses a touch control device and a driving method thereof and a touch control display panel and a driving method thereof. The touch control device comprises multiple drive electrodes which are arranged side by side in the first direction, multiple sensing electrodes which are arranged side by side in the second direction and a control circuit, the multiple drive electrodes are at least divided into a first drive electrode assembly and a second drive electrode assembly, the control circuit is used for driving the electrodes to provide drive signals and detect sensing signals in the sensing electrodes, any two drive electrodes in each drive electrode assembly in the multiple drive electrodes are not scanned simultaneously, any one drive electrode of the second drive electrode assembly and one drive electrode of the first drive electrode assembly are scanned simultaneously, the time for each full screen scanning in the touch control device is shortened, that is to say, in the same time, the frequency of full screen scanning in the touch control device is increased, the scanning frequency of the touch control device is further increased, the point report rate of the touch control device is further increased, and the touch control sensitivity of the touch control device is finally improved.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a touch device and a driving method thereof, a touch display panel including the touch device and a driving method of the touch display panel. Background technique [0002] With the development of touch display technology, touch display devices have been widely used in people's daily life. The existing embedded touch display device usually adopts a time-sharing driving mode during the working process, that is, the time required for one frame is divided into two parts: the display time and the touch time, and during the touch time, all In the above touch display device, the electrodes used as common electrodes during the display time are multiplexed as touch electrodes, so as to adapt to the development trend of thinner and lighter. [0003] However, as the resolution of the touch display device increases, the time that each frame of the screen in the touch display device ...
