The detection of the signal of unit can be realized by the resistance signal between the electrod-array for detecting superstructure and understructure.On
The contact resistance of the force sensing resistance layer of understructure can reduce with the increase of touch display unit stress, and respective power
Due to the influence of quantum tunneling effect, its resistance reduces quick resistive layer with the increase of stress.When touch display unit is not by tactile
When touching, due to force sensing resistance layer 73,74 between there is air layer or air layer in there is insulation spacer 75, the electricity of superstructure
Measured resistance value is infinity between the electrode 720 of pole 710 and understructure.When touch display unit is touched by user
During pressing, force sensing resistance layer 73, the distance between 74 reduces, and when touch pressing reaches certain value, force sensing resistance layer 73,74
Contact with each other, the dynamics with user's touch pressure gradually increases, the area that force sensing resistance layer 73,74 contacts with each other also gradually increases
Greatly, resistance generation between the electrode 710 of corresponding superstructure and the electrode 720 of understructure is corresponding to be reduced.When user touches
After touching pressure increase to a certain extent, the distance of the conductive particle in force sensing resistance layer 73,74 also can be with the increasing of the power for applying
Plus occur reducing, due to quantum tunneling effect, the electron transfer capabilities enhancing between conductive particle, so as to macroscopically be presented as
The resistance value reduction of force sensing resistance layer 73,74.With the increase that is stressed of force sensing resistance layer 73,74, coupled electrode it
Between resistance value be gradually reduced.Therefore, it can set up the electrode resistance in pressure sensitive unit foregoing in touch display unit
The correlation database by force information of change information and touch display unit.In actual applications, it is described to touch display dress
Also include memory and processor in putting, the diverse location being stored with memory in touch display unit carries out different power
Under value is touched, the resistance variations information of each adjacent electrode of power is detected in touch display unit, processor is used for contrast and touches
The resistance variations information of the adjacent electrode that display device detection is obtained and the resistance variations information being pre-stored, so as to judge to touch
The touch information of display device.Wherein touch information includes the size of the power for touching, it is also possible to the position including touch force.
Additionally, the detection of the signal of the pressure sensitive unit can also be by detecting the electricity of superstructure and understructure
Capacitance signal between the array of pole is realized.When detection signal is capacitance signal, between the superstructure and understructure
Insulation spacer can be whole face or local complexity force sensing resistance layer.Insulation spacer can be adhesive, gluing film, insulating oil
Ink etc..Because force sensing resistance layer includes insulating body and the conductive particle being dispersed in insulating body.When touch display unit
During the stress of surface, due to the influence of quantum tunneling effect, its resistance reduces force sensing resistance layer with the increase of stress, now presses
