Abstract

The disclosure discloses an apparatus for detecting an electromagnetic touch. The apparatus includes: a driving subcircuit configured to control organic light-emitting diodes arranged in an array in an organic light-emitting diode display panel to be lightened row by row; a detecting subcircuit configured to obtain detection current flowing through the lightened organic light-emitting diodes in real time, where the detection current of each of the lightened organic light-emitting diodes comprises inductive current of the organic light-emitting diode, and driving current of the organic light-emitting diode being lightened, and the inductive current is current, generated by the organic light-emitting diode, related to a magnetic induction intensity of a magnetic field emitted by a magnetic field emitting apparatus only when the organic light-emitting diode senses the magnetic field; and a first processing subcircuit configured to determine a position of an electromagnetic touch according to the driving current of each of the organic light-emitting diodes, and the obtained detection current thereof.
