Abstract:
1. A combining detection circuit for a display panel applying a switch installed on the combining detection circuit for switching a short-ring layout and a shorting-bar layout, the combining detection circuit for the display panel comprising: a plurality of signal contact pads comprising a plurality of gate end contact pads and a plurality of data end contact pads, a plurality of scan lines and a plurality of data lines of the display panel being connected to an external detection circuit via the plurality of signal contact pads; a plurality of resistances, the plurality of scan lines and the plurality of data lines being connected to a ring signal line via the plurality of resistances; a plurality of data driver signal lines, the plurality of data end contact pads being alternatively connected to the plurality of data driver signal lines via a plurality of conducting wires; a plurality of gate driver signal lines, the plurality of gate end contact pads being alternatively connected to the plurality of gate driver signal lines via the plurality of conducting wires; a plurality of switches positioning on the conducting wires for connecting the plurality of signal contact pads with the plurality of data driver signal lines and the plurality of gate driver signal lines; wherein the plurality of switches are used for switching the detection signal of the display panel to be transmitted to the ring signal line or the plurality of gate driver signal lines and the plurality of gate driver signal lines.
