Plane display, touch control device and touch control detection method

The invention discloses a plane display, a touch control device and a touch control detection method. The touch control device is arranged on a substrate provided with a plurality of scanning lines and comprises a plurality of reading lines and a plurality of sensing elements, the reading lines and the scanning lines are arranged in a mutual crossing way, and the sensing elements are respectively in electrical coupling with a corresponding scanning line and a corresponding reading line, wherein scanning signals are sequentially led into the scanning lines to control whether the sensing elements are started or not, the scanning signals comprise at least one first opening signal and a second opening signal so as to simultaneously start at least two sensing elements, and at least two sensing elements which are simultaneously started are in electrical coupling with different scanning lines. The invention ensures that the scanning signals are provided with at least one first opening signal and the second opening signal by regulating the scanning signals in the scanning lines so as to simultaneously start different sensing elements which are in electrical coupling with different scanning lines, thereby enhancing the density of the sensing elements and promoting the touch control detection capacity without increasing the storage capacity of a detection circuit.
