摘要： The embodiments provide a force touch assembly, a force detection method, a driving detection method and a display apparatus. The force touch assembly may comprise a substrate, a touch sensor and a force sensor provided on the substrate, and a back plate, wherein: the touch sensor is disposed on a first side of the substrate; the force sensor is disposed on a second side of the substrate opposite to the touch sensor, and configured to contact with the substrate; and the back plate is disposed on a side of the force sensor opposite to the substrate, with a gap from the force sensor. The disclosure enables functional layers such as touch sensor and force sensor to be integrated on the same substrate, saving the carrier required for manufacturing the force sensor, reducing the thickness of the force touch assembly, enabling the integration of the assembly into a product having a higher physical strength, and further simplifying the process. The magnitude of the force can be detected based on a capacitor formed by the force sensor and the back plate.
