Claim 2:
3. The terminal control system according to claim 2, wherein the detection chip further comprises:
a first detection module, and a second detection module, wherein
the first detection module is connected to the capacitive sensing layer;
the second detection module is connected to the capacitive sensing layer and the substrate respectively;
the trigger module is connected to the first detection module and the second detection module respectively;
the first detection module is configured to detect the ground capacitor of the capacitive sensing layer, detect the inductive capacitance variation corresponding to the inductive capacitance in response to a generation of the inductive capacitance by the capacitive sensing layer, and determine whether the inductive capacitance variation is greater than the preset first threshold;
the second detection module is configured to detect the interelectrode capacitor between the capacitive sensing layer and the substrate; in a case that the interelectrode capacitance greater than an initial capacitance is generated between the capacitive sensing layer and the substrate, detect the interelectrode capacitance variation corresponding to the interelectrode capacitance; and determine whether the interelectrode capacitance variation is greater than the preset second threshold.
