Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
With reference to Fig. 1 and Fig. 2, Fig. 1 is a kind of touch control detection schematic illustration provided in an embodiment of the present invention, and Fig. 2 is this hair
Another touch control detection schematic illustration that bright embodiment provides.Operating body 21 carries out touch control operation, and touch detection electrodes 22 are used
In the touch control operation of detection operating body 21.The arranged in parallel on X in a first direction of touch detection electrodes 22.Touch detection electrodes 22 exist

The detection port of connection；
Wherein, the scan period of the control circuit includes: touch control detection timing section and display timing section；In touch-control
When sequence section, the control circuit executes the first detection pattern or executes the second detection pattern；
When the control circuit executes the first detection pattern, the control circuit is used for according to the first preset scan orders
The touch detection electrodes are scanned one by one；
When the control circuit executes the second detection pattern, the control circuit is used for according to the second preset scan orders
The touch detection electrodes group is scanned one by one, the touch detection electrodes of same touch detection electrodes group scan simultaneously.
