Force touch assemblies, force detection methods, driving methods and display devices

A method for driving a force touch assembly comprising:

• a substrate, a touch sensor and a force sensor provided on the substrate, a back plate a display switch and a driver IC, wherein the touch sensor is disposed on a first side of the substrate;
• the force 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;
• the back plate is disposed on a side of the force sensor opposite to the substrate, with a gap from the force sensor, and the driver IC is disposed on the first side of the substrate and is located in a non-display area of the force touch assembly, the method comprising:
• driving the display switch to operate during a first preset period;
• driving the touch sensor to operate during a second preset period;
• and
• driving the force sensor to operate during a third preset period;
• wherein the first preset period, the second preset period and the third preset period are not coincident with each other, wherein the driver IC is electrically coupled to the display switch, the touch sensor and the force sensor, and configured to perform the method.

A display device comprising a force touch assembly, wherein the force touch assembly comprises a substrate, a touch sensor and a force sensor provided on the substrate, a back plate, a display switch and a driver IC,

• 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 driver IC is disposed on the first side of the substrate and is located in a non-display area of the force touch assembly;
• and
• the driver IC is electrically coupled to the display switch, the touch sensor and the force sensor, and configured to drive the display switch, the touch sensor and the force sensor by time division.
