Fig. 4 is another structural representation of pressure sensing electric bridge in Fig. 1.The structure of pressure sensing electric bridge shown in Fig. 4 100
It is similar to the structure of pressure sensing electric bridge shown in Fig. 2 100, unlike, first sense of pressure sensing electric bridge 100 in Fig. 4
Resistance 131 and the 3rd inductive reactance 133 is answered to include multiple pierced patterns.
It should be noted that Fig. 2, Fig. 3 and Fig. 4 represent to include to engrave to fill different from the shade of other inductive reactances
The inductive reactance of null pattern, to show difference.In the present embodiment, other induced electricities in addition to the inductive reactance including pierced pattern
Resistance is block resistance, and edge is perpendicular to the rectangular cross-section of inductive reactance thickness direction.
It should also be noted that, the operation principle of pressure sensing electric bridge 100 is as follows：First inductive reactance 131, second senses
Resistance 132, the 3rd inductive reactance 133 and the 4th inductive reactance 134 form wheatstone bridge configuration, when defeated to the first power supply signal
When entering end 111 and 112 input offset voltage signal of second source signal input part, each branch road has electric current to lead in Wheatstone bridge
Cross, now, when pressing display panel, pressure sensing electric bridge 100 is because by the corresponding opening position shearing on display panel
The effect of power, its internal each resistance (including the first inductive reactance 131, the second inductive reactance 132, the 3rd inductive reactance 133 and the
Four inductive reactances 134) deform upon, and then resistance changes, so that the first sensing of pressure sensing electric bridge 100
Pressure sensing electric bridge 100 when the difference of the output electric signal of the induced signal test side 122 of signal detection end 121 and second is with without pressing
The first induced signal test side 121 and the output electric signal of the second induced signal test side 122 difference it is different, accordingly, can be with
Determine the size of touch-control pressure.
It can be seen from the operation principle of above-mentioned pressure sensing electric bridge 100, the electricity of the first power supply signal input of note 111 and second
The bias voltage that source signal input 112 inputs is Uin, the first induced signal test side 121 and the second induced signal test side
The difference of 122 output electric signal is Uout；When not applying pressing force, the resistance of the first inductive reactance 131 is R1, the second induced electricity
The resistance of resistance 132 is R2, and the resistance of the 3rd inductive reactance 133 is R3, and the resistance of the 4th inductive reactance 134 is R4；Apply pressing
After power, the change in resistance amount of the first inductive reactance 131 is Δ R1, and the change in resistance amount of the second inductive reactance 132 is Δ R2, the 3rd
The change in resistance amount of inductive reactance 133 is Δ R3, and the change in resistance amount of the 4th inductive reactance 134 is Δ R4, then Uout=Uin
[(R1+ Δ R1)/(R1+ Δ R1+R2+ Δ R2)-(R4+ Δ R4)/(R3+ Δ R3+R4+ Δ R4)], or Uout=Uin [(R3+
ΔR3)/(R3+ΔR3+R4+ΔR4)-(R2+ΔR2)/(R1+ΔR1+R2+ΔR2)].Under normal circumstances, calculated for simplification
Journey can set the resistance of the first inductive reactance 131, the second inductive reactance 132, the 3rd inductive reactance 133 and the 4th inductive reactance 134
It is worth equal, note R1=R2=R3=R4=R0, then Uout=Uin [(R1+ Δ R1)/(R1+ Δ R1+R2+ Δ R2)-(R4+ Δs
R4)/(R3+ Δ R3+R4+ Δ R4)] can transform to Uout=Uin [(R0+ Δ R1)/(2R0+ Δ R1+ Δ R2)-(R0+ Δ R4)/
(2R0+ Δ R3+ Δ R4)], Uout=Uin [(R3+ Δ R3)/(R3+ Δ R3+R4+ Δ R4)-(R2+ Δ R2)/(R1+ Δs R1+R2+
Δ R2)] Uout=Uin [(R0+ Δ R3)/(2R0+ Δ R3+ Δ R4)-(R0+ Δ R2)/(2R0+ Δ R1+ Δ R2)] is can transform to,
When Δ R1, Δ R2, Δ R3 and Δ R4 are much smaller than R0, Uout=Uin [(R0+ Δ R1)/(2R0+ Δ R1+ Δ R2)-(R0+ Δs
R4)/(2R0+ Δ R3+ Δ R4)] it is reduced to Uout=Uin [(Δ R1- Δ R4)/2R0], Uout=Uin [(R0+ Δ R3)/(2R0
+ Δ R3+ Δ R4)-(R0+ Δ R2)/(2R0+ Δ R1+ Δ R2)] it is reduced to Uout=Uin [(Δ R3- Δ R2)/2R0].Therefore deposit
, 2Uout=Uin [(Δ R1- Δ R4)/2R0]+Uin [(Δ R3- Δ R2)/2R0], therefore Uout=Uin [Δ R1- Δ R4+ Δs
R3-ΔR2)/4R0].It can be seen that increase the electricity of at least one inductive reactance in the first inductive reactance 131 and the 3rd inductive reactance 133
Resistance variable quantity can reach the beneficial effect of the pressure sensitivity detection signal of adherence pressure sensing electric bridge 100.In the present embodiment, pass through
Inductive reactance is arranged to include pierced pattern to reach the effect of the increase inductive reactance resistance change, therefore such as Fig. 2, Fig. 3
Shown in Fig. 4, the first inductive reactance 131 and/or the 3rd inductive reactance 133 are arranged to include pierced pattern.
It should also be noted that, on the one hand due to the inductive reactance side face of the presence of pierced pattern, including pierced pattern
Product increase, and then the lifting surface area of inductive reactance is increased, under identical pressing force, the power that inductive reactance is subject to is more, its shape
Variable is bigger, and resistance change is bigger, on the other hand, relative to the electric resistance structure for not including pierced pattern, including pierced pattern
Inductive reactance in the fringe region more concentrated of stress distribution it is more so that deformation increases in the presence of identical pressing force,
Resistance change increases therewith.

One inductive reactance 131 and/or the 3rd inductive reactance 133 include multiple pierced patterns so that under identical touch control operation, including hollow out
The deformation quantity increase of the inductive reactance of pattern, resistance change rate increase, and then increase the pressure of the output of pressure sensing electric bridge 100
Detection signal, the sensitivity of pressure sensing electric bridge 100 is improved, and because the pressure detecting that pressure sensing electric bridge 100 exports is believed
Number become big so that the pressure detecting signal of pressure sensing electric bridge 100 can be divided into more letters for corresponding to difference in functionality respectively
