The target area is an area capable of deforming the pressure-sensitive module when subjected to pressure.

It is worth noting that the display screen 100 is generally rectangular or approximately rectangular in shape, the direction perpendicular to the display screen 100 is generally considered to be the direction of the thickness of the display screen 100, and the direction of the longer side of the rectangle is the direction of the display screen 100. In the length direction, the direction in which the shorter side of the rectangle is located is the width direction of the display screen 100 .

Further, the electronic device may further include a casing, the display screen 100 may be disposed in the casing, and surround the casing to form an accommodating cavity, and the pressure-sensing module is located in the accommodating cavity.

In the embodiment of the present application, the first deformation member 312, the second deformation member 313 and the reference member 314 jointly form a Wheatstone half-bridge detection circuit, specifically as shown in FIG. 2, R1 is the first deformation member, and R2 is the second deformation member. Two deformation parts, the R parameter is the reference part, when the target area is under pressure, the deformations of R1 and R2 are the same, and the R parameter remains unchanged, so the difference can be output as follows:

The first deformation member 312, the second deformation member 313 and the reference member 314 are all arranged on one side of the base body 311 facing the display screen. side; when the target area is not stressed, the first deformable member 312, the second deformable member 313 and the reference member are all in the first shape; when the target area is stressed, the pressure-sensitive module deforms and outputs a pressure signal , wherein both the first deformable part and the second deformable part are of the second shape, and the reference part is of the first shape. In the embodiment of the present application, by setting the first deformable member 312, the second deformable member 313, and the reference member 314 on one side of the base body 311, a half-bridge detection circuit can be formed through the deformable member and the reference member. When the display corresponding to the pressure-sensitive module When the target area on the screen 100 is under force, the display screen 100 can transmit the force to the pressure-sensitive module, and the deformable part in the pressure-sensitive module is deformed while the reference part is not deformed to output a pressure signal. A deformation member is provided on one side of the 311, which can reduce the thickness of the pressure-sensitive module, thereby reducing the overall thickness of the electronic device and improving user experience.

It is worth noting that the electronic device can also include a control module. When the target area is stressed, the screen transmits the force to the pressure-sensitive module, and the pressure-sensitive module deforms, and at the same time outputs the pressure signal to the pressure-sensitive module. The control module is connected to the module, and the control module generates a corresponding control signal according to the pressure signal to control the electronic equipment. The electronic device may also include components such as a functional module, a battery, etc. The functional module may be a camera module, a flashlight module, an auxiliary display module, a fingerprint module, and the like.

Among them, the pressure sensing module can be set on a flexible printed circuit (FPC), the control module is set on the circuit board, and the FPC is electrically connected to the circuit board. The specific connection structure will not be described in detail in this application. The actual situation is determined.

In order to increase the sensing range of the pressure-sensing module, at least one pressure-sensing module can include multiple pressure-sensing modules, and the multiple pressure-sensing modules can be distributed in multiple positions of the display screen 100 at intervals, so that the sensing range can be as wide as possible. Cover the entire screen to increase user experience.

As shown in FIG. 3 , in a possible implementation of the present application, at least one pressure-sensing module may include a first pressure-sensing module 310 and a second pressure-sensing module 320 arranged at intervals.

In the embodiment of the present application, a larger sensing range can be realized through two pressure-sensing modules, which can not only save costs, but also reduce the number of electronic devices in the electronic equipment.

Both pressure-sensitive modules include a first deformation member 312, a second deformation member 313, a reference member 314 and a base 311, and the first deformation member 312, the second deformation member 313 and the reference member 314 are all arranged on the base 311 facing the display One side of the screen 100.

In a possible implementation manner of the present application, the target area may include a first sub-target area 410 corresponding to the first pressure-sensing module 310 and a second sub-target area 420 corresponding to the second pressure-sensing module 320, respectively. Yes, the pressure signal may include a first sub-pressure signal and a second sub-pressure signal.

Under the condition that the first sub-target area 410 and the second sub-target area 420 are not stressed, the first deformable part 312, the second deformable part 313 and the reference part 314 are all in the first shape; in the first sub-target area 410 When force is applied and the second sub-target area 420 is not stressed, the first pressure-sensitive module 310 deforms and outputs the first sub-pressure signal; when the second sub-target area 420 is stressed, and the first sub-target area 410 In the case of no force, the second pressure-sensing module 320 deforms and outputs a second sub-pressure signal.

Further, since the first pressure-sensing module 310 and the second pressure-sensing module 320 are both arranged on the display screen 100, when the first sub-target area 410 is subjected to force, a certain amount of deformation occurs on the screen, and the second pressure-sensing module 320 will also be subjected to a certain force, therefore, when the first sub-target area 410 is under force, the first deformable part 312 and the second deformable part 313 of the first pressure-sensitive module 310 both change from the first shape to the second shape , the shape of the reference part 314 of the first pressure-sensitive module 310 remains unchanged, or the first shape, and the first deformation part 312 and the second deformation part 313 of the second pressure-sensitive module 320 both change from the first shape to the third shape , the shape of the reference member 314 of the second pressure-sensing module 320 remains unchanged, and is still the first shape. The final output first sub-pressure signal is a pressure signal generated by combining the pressure signals generated by the first pressure-sensing module 310 and the second pressure-sensing module 320 .

If the force is small, the first deformation member 312 and the second deformation member 313 of the first pressure sensing module 310 both change from the first shape to the third shape, and the first deformation member 312 and the second deformation member 313 of the second pressure sensing module 320 The shape of the second deformation member 313 may not change. The first sub-pressure signal output at this time is the pressure signal output by the first pressure-sensing module 310 .

Wherein, the deformation amount of the deformation member of the first pressure-sensing module 310 is greater than the deformation amount of the deformation member of the second pressure-sensing module 320 .

Correspondingly, the stress on the second sub-target area 420 is similar to the force on the first sub-target area 410 described above, and will not be repeated in consideration of the brevity of the text.

Wherein, the deformation amount of the deformation member of the second pressure-sensing module 320 is greater than the deformation amount of the deformation member of the first pressure-sensing module 310 .

Through the deformation of the above-mentioned deformable parts, the control module can determine the pressure signals output by the first pressure-sensing module 310 and the second pressure-sensing module 320, and then control the electronic equipment through the pressure signals, and the different positions of the display screen 100 are stressed. , or the magnitude of the force is different, the pressure signals output by the first pressure-sensing module 310 and the second pressure-sensing module 320 determined by the control module are also different, so a variety of human-computer interaction methods can be realized to meet the needs of users different needs. At the same time, since the pressure can be determined only through the deformation member and the reference member arranged on one side of the base 311, the thickness of the pressure-sensitive module perpendicular to the display screen can be made smaller, thereby reducing the overall thickness of the electronic device. Reduce and improve user experience.

As shown in FIG. 4 , in a possible implementation manner of the present application, the first pressure-sensing module 310 and the second pressure-sensing module 320 are distributed along the length direction of the display screen 100 .

That is, the first pressure-sensing module 310 has a strip-shaped structure, which can make the sensing range of the first pressure-sensing module 310 cover a larger area.

Optionally, the first pressure-sensing module 310 and the second pressure-sensing module 320 are centrally arranged on the display screen 100 .

That is, in order to make the sensing range of the first pressure-sensing module 310 and the second pressure-sensing module 320 larger, the first pressure-sensing module 310 and the second pressure-sensing module 320 can be arranged on the display screen 100 The center position of the display screen 100 is to set the two pressure-sensitive modules at the same distance from the two long sides of the display screen 100 and the same distance from the two short sides of the display screen 100 .

As shown in FIG. 5 , in a possible implementation of the present application, at least one pressure-sensing module may include a first pressure-sensing module 310 and a second pressure-sensing module 320 connected to each other.

Wherein, the two pressure-sensitive modules both include a first deformation member 312, a second deformation member 313, a reference member 314 and a base 311, and the first deformation member 312, the second deformation member 313 and the reference member 314 are all arranged on the base 311 toward on one side of the display screen 100.

In the embodiment of the present application, at least one pressure-sensitive module can be arranged not only along the length direction of the display screen 100, but also along the width direction of the display screen 100. However, since the size of the display screen 100 in the width direction is small, it can The distance between the two unit deformation parts is reduced as much as possible, so as to reduce the overall size of the pressure-sensing module.

To reduce the distance between the two unit deformation parts, the method of reducing the size of the base body 311 may be adopted, or the method of reducing the base body 311 between the two unit deformation parts may be adopted.

In a possible implementation of the present application, the base 311 between the first deformation part of the first pressure-sensing module 310 and the first deformation part of the second pressure-sensing module 320 may be integrally formed.

That is, the substrate between the first deformation member 312 of the first pressure-sensing module 310 and the first deformation member 312 of the second pressure-sensing module 320 can be integrally formed, that is, a substrate is used to support the first pressure-sensing module The first deformable part 312 of the group 310 and the first deformable part 312 of the second pressure-sensitive module 320 can not only reduce the overall size, but also can better transmit the force to the other when one of the deformable parts is stressed. A deformable part, thereby increasing the sensitivity of the pressure-sensitive module.

Furthermore, since the length of the matrix is longer, when one of the units is under pressure, the pressure on the other unit will increase accordingly, that is, the longer the length of the matrix, the better the deformation can be transmitted to the other unit , to further improve the overall sensitivity, therefore, the length of the matrix between the third unit and the fourth unit can be appropriately increased.

Further, there are two reference parts, and the two reference parts are both arranged on the integrally formed base body 311 .

In the embodiment of the present application, no temperature compensation is required for the single-layer deformable part, because the temperature influence is of the same degree. Therefore, the two reference parts 314 on the two substrates 311 at the edge can be omitted, and the two pressure-sensitive modules can directly reuse the reference parts for deformation detection.

As shown in FIG. 6 , in a possible implementation of the present application, the target area may include a third sub-target area 430 corresponding to the first pressure-sensing module 310 and the second pressure-sensing module 320 connected to each other, and the pressure The signal may include a third sub-pressure signal. The first pressure-sensing module 310 and the second pressure-sensing module 320 connected to each other can be regarded as a whole due to the relatively close distance, that is, the whole of the first pressure-sensing module 310 and the second pressure-sensing module 320 and corresponding to the third sub-target area.

The sub-target areas mentioned above all refer to the sensing range of the corresponding unit, and the size of each sub-target area may be the same or different, which is determined according to specific circumstances.

When the third sub-target area 430 is not stressed, the first deformation member 312, the second deformation member 313 and the base body 314 are all in the first shape; when the third sub-target area 430 is stressed, the third unit Both the fourth unit and the fourth unit are deformed and jointly output the third sub-pressure signal.

Further, since the first pressure-sensing module 310 and the second pressure-sensing module 320 are both arranged on the display screen 100, and the distance between them is relatively close, when the third sub-target area 430 is stressed, a certain amount of force will occur on the screen. correspondingly, the first pressure-sensing module 310 and the second pressure-sensing module 320 will also be subjected to a certain force, and the deformation of the deformation parts in the first pressure-sensing module 310 and the second pressure-sensing module 320 The variable may be determined according to the distance between the stress-bearing point of the third sub-target area 430 and the first pressure-sensing module 310 and the second pressure-sensing module 320 .

Specifically, when the distance between the stress-bearing point of the third sub-target area 430 and the first pressure-sensing module 310 is relatively close, the first deformation member 312 and the second deformation member 313 of the first pressure-sensing module 310 both From the first shape to the fourth shape, the shape of the reference part 314 of the first pressure-sensitive module 310 remains unchanged, and it is still the first shape, and the first deformation part 312 and the second deformation part of the second pressure-sensitive module 320 313 all change from the first shape to the fifth shape, and the shape of the reference part 314 of the second pressure-sensitive module 320 remains unchanged, still in the first shape.

Correspondingly, when the force-bearing point of the third sub-target region 430 is relatively close to the second pressure-sensing module 320 , similar to the above-mentioned situation, the text will be concise and will not be repeated here.

There is a certain overlapping area in the sensing ranges generated by two adjacent pressure-sensing modules. Since the distance between the first pressure-sensing module 310 and the second pressure-sensing module 320 is relatively close, the overlapping area is relatively large, and the output of the two The pressure signals are synthesized into one pressure signal, so that the final output pressure signal is enhanced, and the sensitivity of the pressure sensing module can be improved.

Further, since the single-layer deformation member does not need temperature compensation, because the temperature influence can be approximated to the same degree, therefore, the two farthest reference members in the first pressure-sensing module group 310 and the second pressure-sensing module group 320 can be saved. Go, directly use the two reference parts in the middle for deformation detection. Specifically, as shown in FIG. 7 .

That is, the two pressure-sensing modules use the two reference parts in the middle as a reference to form a Wheatstone half-bridge detection circuit. The specific principle and process have been described in detail in the above-mentioned embodiments. Considering the introduction of the text, in this embodiment Do not describe in detail.

In a possible implementation of the present application, at least one pressure-sensing module includes a first pressure-sensing module, a second pressure-sensing module, a third pressure-sensing module and a fourth pressure-sensing module, the first pressure-sensing module The modules and the second pressure-sensing module are distributed along the length direction of the display screen, and the third pressure-sensing module and the fourth pressure-sensing module are distributed along the width direction of the display screen.

That is, a relatively large sensing range can be achieved through four pressure sensing modules, which can not only save costs, but also reduce the number of electronic devices in the electronic equipment.

Wherein, the third pressure-sensing module and the fourth pressure-sensing module can be spaced apart from each other, as shown in FIG. 9; but since the size of the width direction of the display screen 100 is small, the two units can be reduced as much as possible. The distance between the deformation parts is to reduce the overall size of the pressure-sensitive module. At this time, the third pressure-sensitive module and the fourth pressure-sensitive module can be connected to each other. The structure shown in Figure 5 can not only reduce the Small overall size, when one of the deformable parts is stressed, the force can be better transmitted to the other deformable part, thereby increasing the sensitivity of the pressure-sensitive module.
