User input is accepted by a force sensing resistor (“FSR”) assembly, a force sensing capacitor (“FSC”) assembly, or both. The FSR or FSC assemblies may be located within an input device, such as behind a device exterior, display, and so forth. A force applied to the device exterior proximate to the assembly may result in a signal indicative of the force to the assembly. The signal may be processed to determine a particular touch zone was activated. A particular action associated with the touch zone may be performed. The particular action may be based at least in part on which touch zone which was activated, a magnitude of the force, or both. For example, the particular action may include a haptic output to provide feedback to a user.

An input device includes an input surface and a first substrate mechanically coupled to the input surface. The first substrate includes a first plurality of sensor electrodes configured to detect an input force applied by an input object to the input surface. The input device further includes a conductive material disposed between the input surface and the first plurality of sensor electrodes.

A force sensitive touch sensor is configured to distinguish objects touching the surface based on a touch profile. Magnetometers detect the presence, location, orientation, and angle of a stylus comprising a magnet. Presence of the magnetic field in conjunction with touches on the force sensitive touch sensor provides additional comparisons to distinguish whether a touch is from a human hand, a particular portion of a stylus, or other object.

Discussed is a touch display device able to sense a touch position of a user touch and an amount of user touching force. A case disposed below the backlight unit is used as a touching force sensing electrode, enabling a touch display device to sense touch force using the case. A gap is formed by an open area in the bottom cover of the backlight unit, enabling the user touching force to be sensed without an increase in the thickness of the touch display device.
