In addition, a device having an identification module (hereinafter, referred to as an "identification device") may take the form of a smart card, and thus, the identification device may be connected with the mobile terminal 100 via a port or other connection means. The interface unit 170 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal and the external device.
In addition, when the mobile terminal 100 is connected with an external cradle, the interface unit 170 may serve as a path through which power is supplied from the cradle to the mobile terminal 100 or may serve as a path through which various command signals input from the cradle are transmitted to the mobile terminal.

Hereinafter, a slide-type mobile terminal among various types of mobile terminals, such as a folder-type, bar-type, swing-type, slide-type mobile terminal, and the like, will be described as an example for the sake of brevity. Accordingly, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.
The mobile terminal 100 as shown in fig. 1 may be configured to operate with communication systems such as wired and wireless communication systems and satellite-based communication systems that transmit data via frames or packets.
Based on the hardware structure of the mobile terminal, the invention provides various embodiments of the device and the method for reducing the touch screen error report point. The invention discloses a device for reducing touch screen error reporting points, which comprises:
the acquisition module is used for acquiring the position of a touch point of a touch main body on a touch screen when the touch main body touches the touch screen of the device;
the acquisition module is used for acquiring touch parameters of the touch main body by utilizing the full-screen fingerprint device; the touch parameters comprise skin grains of the touch main body and the acquisition positions of the skin grains;
and the processing module is used for judging that the position of the touch point is effective if the relation between the acquisition position and the position of the touch point and the skin lines meet preset touch conditions.
The first embodiment is as follows:
the embodiment provides a device capable of reducing the probability of occurrence of a touch screen error reporting event, and a full-screen fingerprint device is arranged on the device. The full-screen fingerprint device is generally arranged in an overlapping mode with a touch screen, or directly forms one part of the touch screen, and can acquire fingerprint information of a user when the user clicks the touch screen. When a user touches a touch screen of the device, the device can acquire the position of a touch point, and a full-screen fingerprint device on the device is used for collecting touch parameters of a touch main body, and when the collected touch parameters meet certain conditions, the touch point is an effective touch point. By adopting the scheme, whether the position of the touch point is correct or not can be effectively judged before the device reports the touch point to a system, and the cost of the device can be effectively controlled while the touch point reporting accuracy is improved by acquiring touch parameters by using a full-screen fingerprint device on the device.
Referring to fig. 2, this embodiment shows a schematic block diagram of an apparatus for reducing touch screen false alarm points, where the apparatus includes: the device comprises an acquisition module 21, an acquisition module 22 and a processing module 23.
The obtaining module 21 is configured to obtain a touch point position of a touch main body on a touch screen when the touch main body touches the touch screen of the device;
the acquisition module 22 is used for acquiring touch parameters of the touch main body by using a full-screen fingerprint device; the touch parameters comprise skin lines of the touch main body in a preset position range;
and the processing module 23 is configured to determine that the touch point position is valid if the relationship between the touch parameter and the touch point position satisfies a preset touch condition.
In this embodiment, the device for reducing the touch screen error report point may be any device provided with a touch screen and a full-screen fingerprint device, and further, the device may be an existing terminal, including a fixed terminal, such as a smart television capable of touching a screen; the terminal may also be a mobile terminal, such as a smartphone, tablet, laptop, etc.
When the user clicks the touch screen of the device, the obtaining module 21 on the device obtains the position of the touch point. According to a conventional touch screen operation process, after the position of the touch point is obtained, the obtaining module 21 reports the touch point to a system of the device, and the system performs subsequent response according to the position of the touch point, for example, opening an APP located at the position. However, in some cases, a touch screen error point reporting situation may occur, that is, a reported touch point error, where the touch screen error point reporting error includes at least two types:
firstly, when a user normally operates a touch screen, the device identifies the position of a touch point of the user on the touch screen in an error mode, and/or the device identifies the number of times of clicking the touch point of the user on the touch screen in an error mode; for example, referring to fig. 3, the user clicks point a on the touch screen of the device, but the position of the touch point acquired by the acquisition module 21 is point B, or the number of times the user clicks point a on the touch screen is five times, but the number of times the device reports is six times.
Secondly, the user does not have an idea of operating the touch screen, but some objects, such as water drops, which may cause a touch screen reaction, or some parts of the body of the user inadvertently touch the touch screen, so that the acquisition module 21 reports the touch point erroneously, for example, referring to fig. 4, when the user holds the terminal with one hand, the skin of the palm part touches a point C on the edge of the terminal, and the terminal reports the point C as the touch point to the system, so as to form a touch screen error report point, or when the user inadvertently spills water drops on the touch screen of the apparatus during the use of the apparatus, the acquisition module 21 of the apparatus provided with the capacitive touch screen reports the position of the water drop erroneously as the touch point position, so as to form a touch screen error report point.
These can cause a touch screen error point for the device. In order to avoid the occurrence of the false touch point, the validity of the reported touch point needs to be confirmed, including confirming whether the touch point is correct, confirming whether the touch point is the touch point that the user wants to trigger, and the like.
In this embodiment, the correctness of the touch point location is verified based on a full screen fingerprint device on the device. The touch screen with higher cost does not need to be selected while the touch point reporting accuracy is improved. In this embodiment, the obtaining module 21 may obtain the position of the touch point on the touch screen based on a capacitive or resistive touch screen. This embodiment is not limited to this. The touch subject may be any object that can trigger the touch screen to recognize.
After the obtaining module obtains the touch point position, before reporting the touch point position to the mobile phone system, the embodiment determines the validity of the touch point position based on the full-screen fingerprint device. In this embodiment, the capture module 22 is a module that can capture touch parameters of the touch subject by using a full-screen fingerprint device. The touch parameter comprises the acquisition position of the skin texture of the touch main body on the touch screen. The acquisition module 22 acquires the skin texture of the touch subject by using a full-screen fingerprint device, including but not limited to optical fingerprint technology such as infrared fingerprint recognition. After the acquisition module 22 acquires the touch parameters, the processing module 23 can determine that the position of the touch point is valid based on the condition that the acquisition position and the skin texture both meet the condition. And the relation between the acquisition position and the touch point position needs to accord with a preset touch condition.
Generally, when a user consciously operates a touch screen of a device, the user generally uses a finger with high flexibility, and more specifically, the user generally uses the finger belly of the finger to perform operation clicking on the touch screen. The fingerprint pattern on the finger is obviously different from other hand grains or other skin grains of the user body, so that the fingerprint of the finger can be used as the skin grains meeting the preset touch condition by using the full-screen fingerprint device.
In an embodiment, the collection position of the skin texture may be a preset effective range corresponding to the touch point, and the preset effective range may be a range including a position of the touch point on the touch screen, that is, a certain range where the touch point on the touch screen is located. The skin texture is a fingerprint, i.e. the collecting module 22, is used for collecting the fingerprint in the preset effective range corresponding to the touch point position by using the full screen fingerprint device. The processing module 23 is configured to determine that the touch point position is valid if the fingerprint is collected by the collecting module 22, and otherwise, determine that the touch point position is invalid.
After the touch point position is determined to be valid, the processing module 23 may report the valid touch point position to a system of the device, and the system responds to the click operation of the user according to the touch point position.
In another embodiment, the skin texture is a fingerprint, and the fingerprint acquisition position is any position on the touch screen where the fingerprint can be acquired. Namely, the collecting module 22 is configured to collect a fingerprint of the touch subject on the touch screen by using a full-screen fingerprint device, and determine a first position of the fingerprint on the touch screen. Where the fingerprint has an area, the first location may be a range of locations. The processing module 23 is further configured to determine that the touch point position is valid if an overlapping area of a preset valid range corresponding to the first position and the touch point position meets a preset condition; otherwise, judging that the position of the touch point is invalid. The preset condition includes, but is not limited to, that the first position is within a preset effective range corresponding to the touch point position, an overlapping area of the first position and the preset effective range corresponding to the touch point position is not lower than a preset area threshold, or the overlapping area of the first position and the preset effective range corresponding to the touch point position is larger than an area of the first position and the preset effective range corresponding to the touch point position, which are not overlapped, and the like.
How the apparatus of the present embodiment determines that the touch point position is valid is illustrated with reference to fig. 5.
The dotted line section 51 in fig. 5 represents a preset effective range of the touch point D, and the section 52 represents a contact section of the user's finger touching the touch screen. Assuming that the touch point acquired by the acquisition module 21 is point D when the user clicks the screen, the acquisition module 22 acquires a fingerprint of the user on the touch screen and determines a contact interval between the fingerprint and the touch screen, i.e., an interval 52 in fig. 5. The processing module 23 compares the section 51 and the section 52, and if the overlapping area 53 (the shaded portion in the figure) of the sections 51 and 52 meets the preset condition, if the section 52 is within the section 51, the touch point position is valid.
In the above solution, the processing module 23 actually determines whether the touch point position is valid by determining whether there is a fingerprint in a preset valid range of the touch point when the user touches the touch screen. However, a more accurate touch point judgment is also needed for a touch screen point false alarm event caused by the fact that a finger carelessly operates the touch screen at some time. Based on this, in an embodiment, when the collecting module 22 collects the fingerprint, the processing module 23 further determines whether the fingerprint is a preset fingerprint type, and if so, determines that the touch point position is valid; wherein the predetermined fingerprint category includes, but is not limited to, finger belly fingerprints.
In addition, if the user intentionally wants to operate the touch screen of the device, the user intentionally touches the touch screen with a certain pressure and a certain contact area. Therefore, in an embodiment, the acquisition module 22 is further configured to, when the touch subject is a finger, acquire a contact area between the finger and the touch screen when the finger touches the touch screen; and the processing module is further used for judging that the position of the touch point is effective if the contact area is within the preset contact area range.
In addition, when the touch screen is touched, corresponding deformation can occur along with the touch force and the shape of the touch main body, the deformation of the touch screen can be detected through the full-screen fingerprint device, and the pressure of the deformation position of the touch screen can be obtained according to the deformation of the touch screen. Therefore, in an embodiment, the touch parameters further include a pressure of the touch subject in a preset effective range of the touch point position, and the acquisition module 22 is further configured to, when the touch subject is a finger, acquire deformation of the touch screen in the preset effective range corresponding to the touch point position by using a full-screen fingerprint device, and determine the pressure of the finger in the preset effective range corresponding to the touch point position according to the deformation; the processing module 23 is further configured to determine that the touch point position is valid when the pressure is within the preset pressure range.
By adopting the device for reducing the touch screen error report point, when the touch main body touches the touch screen of the device, the touch point position of the touch main body on the touch screen is obtained; acquiring touch parameters of the touch main body by using a full-screen fingerprint device; the touch parameters comprise skin lines of the touch main body and the acquisition positions of the skin lines; and when the relation between the acquisition position and the touch point position and the skin lines meet the preset touch condition, judging that the touch point position is effective. In the scheme of the embodiment, when the user uses the mobile phone through the touch screen, whether the report point on the screen is the real touch point of the user is checked through the full-screen fingerprint device, and the false report point of the touch screen is effectively reduced. The cost of the device is effectively controlled while the touch point reporting accuracy is improved. Is beneficial to the production of the device by the device manufacturer.
Example two:
referring to fig. 6, the present embodiment shows an apparatus for reducing touch screen false alarm points, including: the controller 61, and the user input unit 62, wherein the user input unit 62 includes a touch screen module 621 and a full screen fingerprint module 622. The touch screen module 621 may be implemented by an existing touch screen, and the full-screen fingerprint module 622 may be superimposed on the touch screen to identify skin lines of a user touching the touch screen. The touch screen module 621 and the full-screen fingerprint module 622 of the user input unit 62 are connected to the controller 61, and can input and output data collected by the controller 61.
The touch screen module 621 is configured to, when a touch subject touches a touch screen of the apparatus, obtain a touch point position of the touch subject on the touch screen;
a full screen fingerprint module 622, configured to collect touch parameters of the touch subject; the touch parameters comprise skin lines of the touch main body in a preset position range;
and the controller 61 is configured to determine that the touch point position is valid if the relationship between the touch parameter and the touch point position satisfies a preset touch condition.
In this embodiment, the device for reducing the touch screen error report point may be any device provided with a touch screen and a full-screen fingerprint device, and further, the device may be an existing terminal, including a fixed terminal, such as a smart television capable of touching a screen; the terminal may also be a mobile terminal, such as a smartphone, tablet, laptop, etc.
When the user clicks the touch screen of the device, the touch screen module 621 on the device acquires the position of the touch point. According to a conventional touch screen operation process, after the touch screen module 621 acquires the position of the touch point, the touch point is reported to a system of the device, and the system performs subsequent response according to the position of the touch point, for example, opening an APP located at the position. However, in some cases, a touch screen error point reporting situation may occur, that is, a reported touch point error, where the touch screen error point reporting error includes at least two types:
firstly, when a user normally operates a touch screen, the device identifies the position of a touch point of the user on the touch screen in an error mode, and/or the device identifies the number of times of clicking the touch point of the user on the touch screen in an error mode; for example, the user clicks point a on the touch screen of the device, but the position of the touch point acquired by the touch screen module 621 is point B, or the number of times that the user clicks point a on the touch screen is five times, but the number of times reported by the device is six times.
Secondly, the user does not have an idea of operating the touch screen, but some objects, such as water drops, which may cause a touch screen reaction, or some parts of the body of the user inadvertently touch the touch screen, so that the touch acquisition module 621 mistakenly reports a touch point, for example, when the user holds the terminal with one hand, the skin of the palm part touches the edge of the terminal, thereby forming a touch screen error report point, or when the user carelessly spills water drops on the touch screen of the device during the use of the device, the touch screen module 621 of the device provided with the capacitive touch screen mistakenly reports the position of the water drop as the touch point position, thereby forming a touch screen error report point.
These can cause a touch screen error point for the device. In order to avoid the occurrence of the false touch point, the validity of the reported touch point needs to be confirmed, including confirming whether the touch point is correct, confirming whether the touch point is the touch point that the user wants to trigger, and the like.
In this embodiment, the correctness of the touch point location is verified based on a full screen fingerprint device on the device. The touch screen with higher cost does not need to be selected while the touch point reporting accuracy is improved.
In this embodiment, the touch screen module 621 may obtain a position of a touch point on the touch screen based on a capacitive or resistive touch screen. This embodiment is not limited to this. The touch subject may be any object that can trigger the touch screen to recognize.
After the touch screen module 621 acquires the touch point position, before reporting the touch point position to the device system, the embodiment determines the validity of the touch point position based on the full-screen fingerprint device. In this embodiment, the full-screen fingerprint module 622 is a module that can perform touch parameter collection on a touch subject by using a full-screen fingerprint device. The touch parameter comprises the acquisition position of the skin texture of the touch main body on the touch screen. The full screen fingerprinting module 622 may utilize full screen fingerprinting to capture the skin texture of the touch subject, including but not limited to optical fingerprinting techniques such as infrared fingerprinting. After the full screen fingerprint module 622 collects the touch parameters, the controller 61 can determine that the touch point position is valid based on the condition that the collected position and the skin texture are both satisfied. And the relation between the acquisition position and the touch point position needs to accord with a preset touch condition.
Generally, when a user consciously operates a touch screen of a device, the user generally uses a finger with high flexibility, and more specifically, the user generally uses the finger belly of the finger to perform operation clicking on the touch screen. The fingerprint pattern on the finger is obviously different from other hand grains or other skin grains of the user body, so that the fingerprint of the finger can be used as the skin grains meeting the preset touch condition by using the full-screen fingerprint device. For convenience of explanation, in this embodiment, a device for reducing the touch screen error reporting point is explained.
In an embodiment, the collection position of the skin texture may be a preset effective range corresponding to the touch point, and the preset effective range may be a range including the position of the touch point on the touch screen, that is, a certain range where the touch point on the touch screen is located; the skin lines are fingerprints. Namely, a full screen fingerprint module 622, configured to collect, by using a full screen fingerprint device, a fingerprint within a preset valid range corresponding to the touch point position. The controller 61 is configured to determine that the touch point position is valid if the full screen fingerprint module 622 collects a fingerprint.
After the touch point position is determined to be valid, the controller 61 may report the valid touch point position to a system of the device, and the system responds to the user's click operation according to the touch point position.
In another embodiment, the skin texture is a fingerprint, and the fingerprint acquisition position is any position on the touch screen where the fingerprint can be acquired. Namely, the full screen fingerprint module 622, configured to capture a fingerprint of the touch subject on the touch screen by using a full screen fingerprint device, and determine a first location of the fingerprint on the touch screen. Wherein the fingerprint has a certain area, the first position can be a range without being limited to a point. The controller 61 is configured to determine that the touch point position is valid if an overlapping area of a preset valid range corresponding to the first position and the touch point position satisfies a preset condition. The preset condition includes, but is not limited to, that the first position is within a preset effective range corresponding to the touch point position, an overlapping area of the first position and the preset effective range corresponding to the touch point position is not lower than a preset area threshold, or the overlapping area of the first position and the preset effective range corresponding to the touch point position is larger than an area of the first position and the preset effective range corresponding to the touch point position, which are not overlapped, and the like.
In the above solution, the controller 61 actually determines whether the touch point position is valid by determining whether there is a fingerprint in a preset valid range of the touch point when the user touches the touch screen. However, a more accurate touch point judgment is also needed for a touch screen point false alarm event caused by the fact that a finger carelessly operates the touch screen at some time. Based on this, in an embodiment, when the full screen fingerprint module 622 collects a fingerprint, the controller 61 further determines whether the fingerprint is a preset fingerprint type, and if so, determines that the touch point position is valid; wherein the predetermined fingerprint category includes, but is not limited to, finger belly fingerprints.
In addition, if the user intentionally wants to operate the touch screen of the device, the user intentionally touches the touch screen with a certain pressure and a certain contact area. Therefore, in an embodiment, the full-screen fingerprint module 622 is further configured to, when the touch subject is a finger, obtain a contact area with the touch screen when the finger touches the touch screen; the controller 61 is further configured to determine that the touch point position is valid if the contact area is within the preset contact area range.
In addition, when the touch screen is touched, corresponding deformation can occur along with the touch force and the shape of the touch main body, the deformation of the touch screen can be detected through the full-screen fingerprint device, and the pressure of the deformation position of the touch screen can be obtained according to the deformation of the touch screen. In an embodiment, the touch parameters further include a pressure of the touch subject in a preset effective range of the touch point position, and the full-screen fingerprint module 622 is further configured to, when the touch subject is a finger, obtain a deformation of the touch screen in the preset effective range corresponding to the touch point position, and determine, according to the deformation, the pressure of the finger in the preset effective range corresponding to the touch point position; and the controller 61 is further configured to determine that the touch point position is valid when the pressure is within the preset pressure range.
By adopting the device for reducing the false alarm points of the touch screen, when a user uses a mobile phone through the touch screen, whether the screen alarm points are real touch points of the user is verified through the full-screen fingerprint device, and the false alarm points of the touch screen are effectively reduced. The cost of the device is effectively controlled while the touch point reporting accuracy is improved. Is beneficial to the production of the device by the device manufacturer.

and S703, if the relation between the touch parameters and the touch point position meets the preset touch condition, judging that the touch point position is effective.
In this embodiment, the device for reducing the touch screen error report point may be any device provided with a touch screen and a full-screen fingerprint device, and further, the device may be an existing terminal, including a fixed terminal, such as a smart television capable of touching a screen; the terminal may also be a mobile terminal, such as a smartphone, tablet, laptop, etc.
When a user clicks a touch screen of the device, the device can acquire the position of the touch point. According to a conventional touch screen operation process, the device reports the touch point to a system of the device after acquiring the position of the touch point, and the system performs subsequent response according to the position of the touch point, for example, opening an APP located at the position. However, in some cases, a touch screen error point reporting situation may occur, that is, a reported touch point error, where the touch screen error point reporting error includes at least two types:
firstly, when a user normally operates a touch screen, the device identifies the position of a touch point of the user on the touch screen in an error mode, and/or the device identifies the number of times of clicking the touch point of the user on the touch screen in an error mode; for example, the user clicks point a on the touch screen of the device, but the position of the obtained touch point is point B, or the number of times the user clicks point a on the touch screen is five times, but the number of times the device reports is six times.
Secondly, the user does not have an idea of operating the touch screen, but some objects, such as water drops, which may cause a touch screen reaction, or some parts of the user body touch the touch screen carelessly, so that a touch point is reported erroneously, for example, when the user holds the terminal with one hand, the skin of the palm part touches the edge C of the terminal, and the terminal reports the C as the touch point to the system, so as to form a touch screen error report point, or when the user carelessly sprinkles water drops on the touch screen of the device during the use of the device, so that the device provided with the capacitive touch screen reports the position of the water drop as the touch point position erroneously, so as to form a touch screen error report point.
These can cause a touch screen error point for the device. In order to avoid the occurrence of the false touch point, the validity of the reported touch point needs to be confirmed, including confirming whether the touch point is correct, confirming whether the touch point is the touch point that the user wants to trigger, and the like.
In this embodiment, the correctness of the touch point location is verified based on a full screen fingerprint device on the device. The touch screen with higher cost does not need to be selected while the touch point reporting accuracy is improved. The embodiment may be based on a capacitive or resistive touch screen to obtain the position of a touch point on the touch screen. This embodiment is not limited to this. The touch subject may be any object that can trigger the touch screen to recognize.
In the above process, the acquiring of the touch point position and the acquiring of the touch parameter may be performed simultaneously, and the order of S701 and S702 is not limited in this embodiment.
S701-S703 in this embodiment are processes of checking validity of the touch point position before reporting the touch point position to the device system, where this embodiment determines the validity of the touch point position based on a full-screen fingerprint device. In this embodiment, the touch parameter includes, but is not limited to, the position of the skin texture of the touch subject on the touch screen. The way of acquiring the skin texture of the touch subject by using the full-screen fingerprint device includes, but is not limited to, optical fingerprint technology, such as infrared fingerprint identification. After the touch parameters are collected, the position of the touch point can be judged to be effective only by determining that the collection position and the skin lines meet the conditions. Further, the relationship between the acquisition position and the touch point position needs to meet a preset touch condition.
Generally, when a user consciously operates a touch screen of a device, the user generally uses a finger with high flexibility, and more specifically, the user generally uses the finger belly of the finger to perform operation clicking on the touch screen. The fingerprint pattern on the finger is obviously different from other hand grains or other skin grains of the user body, so that the fingerprint of the finger can be used as the skin grains meeting the preset touch condition by using the full-screen fingerprint device.
In an embodiment, the collection position of the skin texture may be a preset effective range corresponding to the touch point, and the preset effective range may be a range including the position of the touch point on the touch screen, that is, a certain range where the touch point on the touch screen is located; the skin lines are fingerprints. Namely, step S702 includes: and collecting the fingerprints in the preset effective range corresponding to the touch point position by using a full-screen fingerprint device. Step S703 includes: and if the fingerprint is collected in the preset effective range corresponding to the touch point position, judging that the touch point position is effective. After the touch point position is judged to be valid, the valid touch point position can be reported to a system of the device, and the system responds to the click operation of the user according to the touch point position.
In another embodiment, the skin texture is a fingerprint, and the fingerprint acquisition position is any position on the touch screen where the fingerprint can be acquired. Namely, step S702 includes: the method comprises the steps of collecting a fingerprint of a touch main body on a touch screen by using a full-screen fingerprint device, and determining a first position of the fingerprint on the touch screen. Where the fingerprint has an area, the first location may be a range of locations. Step S703 includes: and if the overlapping area of the first position and the preset effective range corresponding to the touch point position meets the preset condition, judging that the touch point position is effective. The preset condition includes, but is not limited to, that the first position is within a preset effective range corresponding to the touch point position, an overlapping area of the first position and the preset effective range corresponding to the touch point position is not lower than a preset area threshold, or the overlapping area of the first position and the preset effective range corresponding to the touch point position is larger than an area of the first position and the preset effective range corresponding to the touch point position, which are not overlapped, and the like.
In the above scheme, when the user touches the touch screen, the validity of the position of the touch point is actually determined by whether a fingerprint exists in the preset valid range of the touch point. However, a more accurate touch point judgment is also needed for a touch screen point false alarm event caused by the fact that a finger carelessly operates the touch screen at some time. Based on this, in an embodiment, in S702, after the fingerprint is collected, before the touch point position is determined to be valid, the method further includes determining whether the fingerprint is a preset fingerprint type, and if so, determining that the touch point position is valid; otherwise, it is invalid. Wherein the predetermined fingerprint category includes, but is not limited to, finger belly fingerprints.
In addition, if the user intentionally wants to operate the touch screen of the device, the user intentionally touches the touch screen with a certain pressure and a certain contact area. Therefore, in an embodiment, after the fingerprint is collected, before the touch point position is judged to be valid, when the touch main body is a finger, the contact area between the touch main body and the touch screen when the touch main body is the finger is acquired; and the processing module is further used for judging that the position of the touch point is effective if the contact area is within the preset contact area range.
In addition, when the touch screen is touched, corresponding deformation can occur along with the touch force and the shape of the touch main body, the deformation of the touch screen can be detected through the full-screen fingerprint device, and the pressure of the deformation position of the touch screen can be obtained according to the deformation of the touch screen. In one embodiment, the touch parameters further include pressure of the touch main body in a preset effective range of the touch point position, after the fingerprint is collected, before the touch point position is judged to be effective, when the touch main body is a finger, deformation of the touch screen in the preset effective range corresponding to the touch point position is obtained by using a full-screen fingerprint device, and the pressure of the finger in the preset effective range corresponding to the touch point position is determined according to the deformation; and if the pressure is within the preset pressure range, judging that the position of the touch point is effective.
