Abstract
The present invention provides a detecting circuit, a detecting method and a display device, and the detecting circuit includes data signal input buses, switching units and control units, wherein the data signal input buses are used to provide data signals to the data lines and a predetermined number of data lines corresponding to a central region of the display panel constitute a first data line group; the switching units are arranged between the data lines and corresponding data signal input buses, all of which are divided into two switching unit groups, and all switching units in correspondence with the data lines in the first data line group constitute a first switching unit group; and the control units are used to control all switching units of corresponding switching unit groups to be turned on or turned off simultaneously.
