Abstract
Disclosed are a three-dimensional (3D) touch control structure and a display device. The three-dimensional (3D) touch control structure includes: a plurality of magnetic field generating components arranged into an array, and a plurality of electromagnetic inducting components in one-to-one correspondence and arranged in different layers to the magnetic field generating components; wherein a distance exists between the magnetic field generating components and the corresponding electromagnetic inducting components, and the magnetic field generating components are configured for generating magnetic fields and the electromagnetic inducting components are configured for changing in induced potential during touch control.
