Apply biasing voltage signal on 13, and first resistor R1, second resistance R2,3rd resistor R3 and the 4th resistance R4 resistance meet
In the case of above-mentioned relation, the partial pressure on first resistor R1 is identical with the partial pressure on the 4th resistance R4, point on second resistance R2
Pressure is identical with the partial pressure on 3rd resistor R3.When without pressing, pressure sensor the first induced signal measurement end Vout1 and second
Current potential between induced signal measurement end Vout2 is equal, the first induced signal measurement end Vout1 and the second induced signal measurement end
The pressure sensitivity detection signal of Vout2 outputs is 0.During pressing, the pressure sensitivity detection signal that pressure sensor 13 exports is equal to before and after pressing
The pressure sensitivity change in detection signal amount that pressure sensor 13 exports.So be advantageous to simplify the calculating process of touch-control pressure value, reduce
Display panel performs the response time of respective operations according to touch-control pressure size.
Typically, under no pressed state, first resistor R1, second resistance R2,3rd resistor R3 and the 4th resistance R4 resistance
Value is equal.So, in the case of without pressing, the first induced signal measurement end Vout1 and the second induced signal measurement end Vout2
Between current potential it is equal, the first induced signal measurement end Vout1 and the second induced signal measurement end Vout2 output pressure sensitivity detection
Signal is 0, is so advantageous to simplify the calculating process of touch-control pressure value, reduction display panel is according to the execution pair of touch-control pressure size
The response time that should be operated.
With continued reference to Fig. 9, first resistor R1 and 3rd resistor R3 in a first direction 100 development length be more than in second party
To 200 development length, second resistance R2 and the 4th resistance R4 are more than in a first direction in the development length of second direction 200
100 development length；Wherein, first direction 100 and second direction 200 are parallel with plane where display panel, and first party
Intersect to 100 and second direction 200.In this way, first resistor R1 and 3rd resistor R3 can be caused mainly to sense first party
To the strain on 100, second resistance R2 and the 4th resistance R4 mainly sense the strain in second direction 200.First resistor R1 feels
The direction that should be strained is different from the direction of second resistance R2 sensing strains, the direction of the 4th resistance R4 sensing strains and 3rd resistor
The direction of R3 sensing strains is different, and then can be by first resistor R1, second resistance R2, and 3rd resistor R3 and the 4th resistance
R4 is laid in space same place or closely located position, so that first resistor R1 and second resistance R2, and the 3rd
Resistance R3 and the 4th resistance R4 have pulling temperature change, eliminate the influence of temperature difference, improve pressure sensitive precision.
Further, alternatively, first direction 100 and second direction 200 are vertical.During pressing, same position exists
The difference of deformation quantity is maximum in mutually perpendicular direction, sets first direction 100 and second direction 200 vertical, can be further
Increase the pressure sensitivity inspection of the first induced signal measurement end Vout1 and the second induced signal measurement end Vout2 output of pressure sensor
Signal is surveyed, improves the purpose of the sensitivity of pressure sensor.
In actual setting, it is contemplated that strain sensitivity system of the ga(u)ge factor of semi-conducting material than metal material
The high magnitudes of number, alternatively, first resistor R1, second resistance R2,3rd resistor R3 and the 4th resistance R4 material are non-

The effect of corresponding opening position shearing force on panel, its internal equivalent resistance Ra, equivalent resistance Rb, equivalent resistance Rc and equivalent
At least one impedance changes in resistance Rd, so that the first induced signal measurement end Vout1 of pressure sensor 13
Believe with the pressure sensitivity detection signal of the second induced signal measurement end Vout2 outputs with the first sensing without pressure sensor 13 when pressing
The pressure sensitivity detection signal of number measurement end Vout1 and the second induced signal measurement end Vout2 outputs is different, accordingly, it may be determined that touches
The size of governor pressure.
Alternatively, the shape of sensor main body 130 can be square.The benefit so set is to advantageously allow
It is identical with equivalent resistance Rd resistance to imitate resistance Ra, equivalent resistance Rb, equivalent resistance Rc, so, in the case of without pressing, first
