Detailed Description
The embodiments described in the exemplary embodiments below do not represent all embodiments consistent with the present application's patent, but rather are merely examples of apparatus and methods consistent with the present application's aspects patent, as detailed in the appended claims.
As used in this application and the appended claims, the singular forms "," "said," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It is to be understood that although the terms , second, third, etc. may be used herein to describe various information, these information should not be limited to these terms.
Taking the call anti-false touch function of the mobile phone as an example, in the related art, an infrared distance sensor may be disposed in a hole on the front surface of the mobile phone (e.g., on the cover glass), and the infrared distance sensor detects the distance between the mobile phone and the blocking object by emitting infrared rays and receiving infrared rays reflected back by the blocking object in front of the mobile phone, and stops the screen when the distance reaches threshold value to prevent the blocking object from causing false touch to the screen of the mobile phone.
However, in the aspect of detecting the distance between the mobile phone and the shielding object based on infrared rays, , when the position of the infrared distance sensor on the front of the mobile phone has objects which are easy to interfere with the infrared rays, such as oil stain, dust, hair, etc., the accuracy and sensitivity of detection are low, and in the aspect of , holes are needed to be formed in the front of the mobile phone (usually near the receiver and the front camera of the mobile phone) to seriously affect the aesthetic property of the front of the mobile phone and reduce the screen occupation ratio of the screen of the mobile phone.
Accordingly, the present disclosure is directed to solving the above-mentioned problems in the related art by improving a manner of detecting a blocking object.
FIG. 1 is a schematic diagram of the structure of electronic devices according to an exemplary embodiment, as shown in FIG. 1, the electronic devices include an antenna structure and an electric field receiving portion, wherein the antenna structure is configured as an electric field emitting portion, the electric field receiving portion is located in a preset input component 10 (which may be located at a preset surface of the electronic device, such as a cover glass, without being limited by the present disclosure), the electric field emitting portion is located below the preset input component 10. by the emission of the electric field by the electric field emitting portion and the reception of the electric field by the electric field receiving portion, an electric field may be formed between the electric field receiving portion and the electric field emitting portion, and the electric field may be shunted with the electrical conductors in close proximity thereto. in , the electric field may include a main electric field located between the electric field emitting portion and the electric field receiving portion, and a fringe electric field extending to the outside of the electronic device (i.e., above the preset input component 10 in FIG. 1). The fringe electric field may be formed at the preset surface of the electronic device, and the fringe electric field may be shunted by the electrical conductors in close proximity thereto, since the.
Based on the structure of the electronic device in fig. 1 and the principle that the electric field can be shunted by the nearby conductive body, it can be determined whether there is a conductive body near the electronic device (i.e. near the preset input part 10) according to the shunting situation of the electric field, as shown in fig. 2, when the conductive body 20 is near the electronic device, the fringe electric field is guided to the conductive body 20, i.e. shunted by the conductive body 20, at this time, the electric field emitting part is the pole plate, the conductive body 20 is the second pole plate, the pole plate, the second pole plate and the electric field therebetween (at least part of the fringe electric field) jointly constitute a capacitor, and when the conductive body 20 moves step closer to the electronic device, as shown in fig. 3, the distance D between the conductive body 20 (second pole plate) and the electric field emitting part (the pole plate) decreases, and the facing area S of the pole plate and the second pole plate (facing area corresponding to the fringe electric field directed from the pole plate to the:
Figure BDA0001735222520000071
c is a capacitance value;
ε is the absolute permittivity of the dielectric;
ε 0 is the vacuum permittivity of the dielectric;
s is the opposite area between the two polar plates;
d is the distance between the two polar plates.
From the above formula, the Capacitance value C is increased when the conductor 20 approaches the electronic device in steps, and therefore, the electric field receiving part measures the Capacitance value of the capacitor formed by the fringe electric field and the electric field emitting part and the conductor 20 to determine the branching of the electric field (fringe electric field) by the conductor 20, and thereby determine the distance between the conductor 20 and the electronic device.
As can be seen from the above description, the distance between the electronic device (i.e., the predetermined input unit 10) and the conductive body 20 (i.e., the approaching distance of the conductive body 20) can be reflected by the change of the capacitance value. While the following interference factors may exist in detecting the capacitance value: 1) the interference of the main electric field with the electric field reception portion measurement capacitance (the fringe electric field with the capacitance of the capacitor formed by the electric field emission portion and the conductor 10); 2) the direction in which the electrical conductors approach. The following is a detailed description of the two interference factors.
1. Interference of main electric field on electric field receiving part measuring capacitance value
As can be seen from the description of fig. 1-3, the main electric field is located inside the electronic device. Other conductors, such as metal sheets, Laser-Direct-structuring (LDS), Flexible Printed Circuit (FPC), etc., often exist inside the electronic device. The other conductor, the electric field emission portion and the main electric field may also constitute a capacitor, so that the electric field reception portion may also measure a capacitance value, which causes interference to the electric field reception portion in measuring the capacitance value of the capacitor constituted by the fringe electric field.
Thus, an isolation layer 30 may be disposed near the electric field receiving portion for isolating at least a portion of the main electric field, as shown in FIG. 4, the isolation layer 30 may be disposed between the electric field receiving portion and the electric field emitting portion, for example, the isolation layer 30 is disposed directly below the electric field receiving portion to isolate portions of the main electric field, and to reduce the capacitance of the capacitor formed by the other electrical conductors and the electric field emitting portion and the main electric field, thereby reducing the interference of the measurement of the capacitor corresponding to the fringe electric field.
2. Direction of approach of electric conductors
As shown in FIG. 5, the main antenna 51 is closer to the preset surface 53 than the diversity antenna 52 (i.e. the main antenna 51 is closer to the front 53 of the electronic device 5 and the diversity antenna 52 is closer to the back 54 of the electronic device 5 than the diversity antenna 52), the main antenna 51 emits a fringe sub-electric field, the fringe sub-electric field of the second forms a first capacitor with the main antenna 51 and the conductive body 20, the capacitance value of the first 3634 is that of the diversity antenna 52, the fringe sub-electric field of the diversity antenna 52 forms a second fringe sub-electric field, the fringe sub-electric field of the second forms a second 3652 capacitor with the main antenna 51 and the conductive body 20, and the capacitance value of the second antenna is that the electrical field is closer to the conductive body 20 than the electrical capacitance value of the main antenna 51, the electrical capacitance value of the second antenna 52 is that of the electrical field of the second fringe sub-electric field is greater than the electrical field of the conductive body of the main antenna 51 and the conductive body 20, and the electrical capacitance value of the second antenna 52 is greater than the electrical capacitance value of the electrical field of the electrical conductor 20, and the electrical field of the electrical conductor is greater than the electrical capacitance value of the second antenna 52, and the electrical conductor 20, and the electrical capacitance value of the electrical conductor is greater than the electrical capacitance value of the electrical conductor 595, and the electrical capacitance value of the electrical conductor is greater than the electrical conductor when the electrical capacitance value of the electrical conductor 20.
It should be noted that the positions of the main antenna 51 and the diversity antenna 52 in the electronic device 5 can be flexibly set according to practical situations, and the present disclosure does not limit this. For example, as shown in fig. 5, the main antenna 51 may be located at the side of the middle frame within the electronic device 5, and the diversity antenna 52 may be located at the bottom of the middle frame.
In addition, , the electric field emitting part (antenna structure) and the electric field receiving part can be hidden below a touch screen (or cover glass) of the electronic equipment (i.e. inside the electronic equipment), so that holes can be avoided, the screen occupation ratio of the mobile phone can be improved, and meanwhile, the limitation of the optical detection principle on the color of the touch screen (or the color of the cover glass above the touch screen) (different absorption and reflection effects of materials with different colors on light rays) can be broken through, so that richer colors can be designed for the front of the electronic equipment such as the mobile phone.
Referring to fig. 6, fig. 6 is a flowchart illustrating a false touch prevention method for electronic devices according to an exemplary embodiment of , the electronic device including an antenna structure configured as an electric field emitting part and forming an electric field with the electric field receiving part, and the false touch prevention method may include:
in step 602, the electrical field is monitored for shunting.
In this embodiment, the electric field can be shunted with the electrical conductors in close proximity. Wherein, the electric conductor can be human skin. For example, the skin of the user's face, palm, fingers, etc. may be used.
As can be seen from the embodiments shown in FIGS. 1-3, the electric field includes a main electric field between the electric field emitting portion and the electric field receiving portion, and a fringe electric field extending to the outside of the electronic device, wherein the fringe electric field is shunted by the conductive body, when the shunting of the electric field is monitored, the capacitance of the capacitor formed by the fringe electric field, the electric field emitting portion and the conductive body is monitored, and the shunting of the fringe electric field is determined according to the variation of the capacitance.
In step 604, it is determined whether the conductive object is present near the electronic device based on the shunting condition.
In this embodiment, the preset input unit may be disposed on a preset surface of the electronic device, the antenna structure includes a main antenna and a diversity antenna, the main antenna is closer to the preset surface than the diversity antenna, the electric field includes a main electric field between the electric field emitting portion and the electric field receiving portion, and a fringe electric field extending to the outside of the electronic device, the fringe electric field includes a th fringe sub-electric field formed by emission of the main antenna and a second fringe sub-electric field formed by emission of the diversity antenna, based on the above description of the embodiment shown in fig. 5, a direction of approaching the conductive object may be determined by a magnitude relationship between a th capacitance value and a second capacitance value, and thus, a 38964 th capacitance value of the nd fringe sub-electric field and a th capacitor formed by the main antenna and the conductive object may be monitored, and a second capacitance value of the second capacitor formed by the diversity antenna and the conductive object may be determined to be increased by at least a preset amount (368678) corresponding to the preset capacitance value when the th capacitance value is greater than the second capacitance value and the is changed by a preset value.
In step 606, a preset input component of the electronic device is locked when it is determined that the conductive object is present proximate to the electronic device.
In this embodiment, when the preset function of the electronic device is turned on, the shunt condition of the electric field may be monitored, so as to determine whether there is a conductive body close to the electronic device according to the shunt condition. For example, the preset function may be a call function; then, the shunting condition of the electric field can be monitored when the call function of the electronic device is turned on (i.e. the user is using the electronic device to make a call, and the electronic device is in a call state). Monitoring electric field when the conversation function at electronic equipment is opened to the input part is predetermine in the locking when judging that there is the electric conductor to be close to electronic equipment, can effectively prevent that the electric conductor from to this mistake of predetermineeing the input part touching the operation, improving the operating efficiency to electronic equipment, and promote user experience. For example, the false touch prevention scheme is applied to a scene of preventing false touch during mobile phone conversation (in the scene, the electronic device is a mobile phone; the preset input component is a touch screen; the electric conductor can be the face or fingers of a user using the mobile phone, and the like), and when the situation that the electric conductor is close to the mobile phone (namely close to the touch screen) is judged, the touch screen of the mobile phone can be locked to prevent the electric conductor from causing false touch on the touch screen.
For ease of understanding, the disclosed solution is further illustrated with reference to specific scenarios and figures.
Referring to fig. 7, fig. 7 is a flowchart illustrating a method for preventing accidental touch of another kinds of electronic devices according to an exemplary embodiment of , where as shown in fig. 7, the method is applied to electronic devices such as a mobile phone, and may include the following steps:
in step 702, the state of the handset is detected.
In the present embodiment, the mobile phone is provided with an antenna structure and an electric field receiving section. The antenna structure and the electric field receiving portion form a specific description of an electric field, and the principle of determining whether a conductor close to the mobile phone exists by utilizing the electric field shunting condition may refer to the structural part of the electronic device, which is not described herein again.
In step 704, it is determined whether the call function of the mobile phone is enabled, if so, step 706 is performed, otherwise, step 702 is performed.
In step 706, the th and second capacitance values are monitored.
In this embodiment, based on the analysis of the embodiment shown in FIG. 5, the th capacitance value and the second capacitance value can be monitored to determine the direction of the conductive object approaching the touch screen of the mobile phone, wherein the th capacitance value and the second capacitance value can be measured by the CDC in the electric field receiving portion.
In step 708, it is determined whether the th capacitance is greater than the second capacitance, and if the th capacitance is greater than the second capacitance, the process proceeds to step 710, otherwise the process returns to step 706.
In this embodiment, when the th capacitance is larger than the second capacitance, it can be determined that the conductive body is close to the touch screen from the touch screen side (i.e. the front side) of the mobile phone.
In step 710, it is determined whether the th capacitance value is changed by a predetermined amount, if the th capacitance value is changed by a predetermined amount, the process proceeds to step 712, otherwise, it is determined whether the th capacitance value is changed by a predetermined amount.
In step 712, the touch screen is locked.
For example, the preset change may be that the increase of the th capacitance exceeds a preset increase, or the th capacitance reaches or exceeds a preset threshold, when the th capacitance is changed by the preset change, it is determined that the th edge sub-electric field is shunted, and the touch screen may be locked to prevent the conductive body from causing a false touch to the touch screen.
For example, in cases, the preset change is that the increase of the capacitance value exceeds the preset increase, assuming that the preset increase is Δ a, when the increase of the capacitance value exceeds Δ a, it is determined that the th edge sub-electric field is shunted, that is, it indicates that there is a conductive object close to the mobile phone, and at this time, the touch screen of the mobile phone can be locked to prevent accidental touch, in another cases, it is determined that the th capacitance value reaches the preset threshold, assuming that the b is the b, when the th capacitance value reaches or exceeds b, it is determined that the th edge sub-electric field is shunted, that is, it indicates that there is a conductive object close to the mobile phone, and at this time, the touch screen of the mobile phone can be locked to prevent accidental touch.
