Touch display panel detection circuit and method as well as touch display panel

The invention relates to a touch display panel detection circuit and method as well as a touch display panel. The detection circuit is characterized in that the grid electrodes of first to fourth transistors are electrically connected with a switch terminal; the first transistor is electrically connected between group nodes of a first data terminal and a first data line; the first transistor is electrically connected between group nodes of a second data terminal and a second data line; the first transistor is electrically connected between group nodes of a first public terminal and a first public electrode block; and the fourth transistor is electrically connected between group nodes of a second public terminal and a second public electrode block. According to the touch display panel detection circuit and method as well as the touch display panel, the quantity of detection terminals can be decreased and benefit is brought to the narrow-edge cable routing design of borders. 本申请涉及种触控显示面板的检测电路及检测方法、触控显示面板。该检测电路包
