The present application relates to a detection circuit and a detection method for a touch control display panel and the touch control display panel. The detection circuit adopts the structure that a gate electrode of a first transistor and a gate electrode of a second transistor are electrically connected with a data switch terminal; the first transistor is electrically connected between a first data terminal and a first data line group node; the second transistor is electrically connected between a second data terminal and a second data line group node; a gate electrode of a third transistor and a gate electrode of a fourth transistor are electrically connected with a public switch terminal; a drain electrode of the third transistor is electrically connected with the second data terminal; a source electrode of the third transistor and a drain electrode of the fourth transistor are electrically connected with a first public electrode block group node; and a source electrode of the fourth transistor and a public terminal are electrically connected with a second public electrode block group node. According to the detection circuit and the detection method for the touch control display panel and the touch control display panel, which are disclosed by the present application, the number of detection terminals can be reduced; and the detection circuit and the detection method for the touch control display panel and the touch control display panel are beneficial to side narrowing of a border and routing design.
