Display device, pressure detection method and pressure detection device

The invention discloses a display device, a pressure detection method and a pressure detection device. An FPC electrode located on the side, facing a display panel, of an FPC, an upper electrode which is located on the side, facing the FPC, of the display panel and is grounded, and a dielectric material which is located between the FPC electrode and the upper electrode, makes contact with the FPC electrode and the upper electrode and has elastic deformation capacity are additionally arranged between the display panel and the FPC; or an FPC electrode located on the side, facing a whole machine middle frame, of the FPC, and a dielectric material which is located between the FPC electrode and the whole machine middle frame, makes contact with the FPC electrode and the whole machine middle frame and has elastic deformation capacity are additionally arranged between the FPC and the whole machine middle frame to detect pressure acting on the display panel, so that the problem that an existing display device cannot achieve pressure detection is solved, and user experience is improved.
