Abstract
The disclosure discloses a method and apparatus for detecting an electromagnetic touch, where organic light-emitting diodes arranged in an array in an organic light-emitting diode display panel are controlled to be lightened row by row, and detection current flowing through the lightened organic light-emitting diodes is obtained in real time. The detection current of each of the lightened organic light-emitting diodes includes inductive current of the organic light-emitting diode, and driving current of the organic light-emitting diode being lightened, and the inductive current is the current, generated by the organic light-emitting diode, related to magnetic induction intensity of a magnetic field emitted by a magnetic field emitting apparatus only when the lightened organic light-emitting diodes senses the magnetic field, a position of an electromagnetic touch can be determined according to the driving current of each of the organic light-emitting diodes, and the obtained detection current thereof.
