Therefore the corresponding of resistance variations of the size of touch-screen diverse location pressure with straining inductor can be set up
Relation.In follow-up detection, the touching position information and the resistance of strain inductor collected according to touch-screen
Change information may determine that the pressure information of the touch pressing of touch-screen.
Influence of the generation to the resistance variations signal of strain inductor is strained due to lead to avoid or reducing,
Line width of the line width of the lead much larger than the strain inductor, that is to say, that the resistance of lead is much smaller than should
Become the resistance of inductor.Much smaller than be defined herein as be less than or equal to five times and more than, further, less than etc.
In ten times and more than.
Because the resistance of graphene or CNT is greatly influenced by temperature, therefore in certain embodiments, institute
Stating touch-screen also includes temperature-compensating inductor.The structure phase of temperature-compensating inductor and the strain inductor
It is same or similar, for example can be pectinate texture or serpentine configuration.The temperature-compensating inductor senses with strain
Device is in close or identical temperature environment.In certain embodiments, the temperature-compensating inductor with it is described
Inductor is strained to be located on same base material.Further, the temperature-compensating inductor is located at the side of touch-screen
Edge position.Because temperature-compensating inductor is located at the edge of touch-screen, when touch-screen is touched, its deformation is non-
Often small, the resistance variations of temperature-compensating inductor are very small, and the change in resistance compared to strain inductor can be with
Ignore.
It is appreciated that temperature-compensating inductor can be not present in touch-screen, and by the electronics including touch-screen
Other electron component in equipment is carried out to the signal for being caused the resistance variations of strain inductor due to temperature change
Compensation.
In certain embodiments, for avoid it is described strain inductor or temperature-compensating inductor be pointed to same base
The function effect of touch driving electrodes and/or touch sensible electrode on material, temperature-compensating inductor, strain sense
Answer between device and touch driving electrodes and/or touch sensible electrode on same base material with the wire of ground connection every
Open.Or, touch sensing unit can be made to be in different work from strain inductor and temperature-compensating inductor
Time, i.e., time-sharing work is carried out according to different signal detection frequencies.
In certain embodiments, it is the resistance detection changing sensitivity of enhancing strain inductor, in touch-screen
