More or fewer components may alternatively be implemented. Elements of the mobile terminal will be described in detail below.

The wireless communication unit 110 typically includes one or more components that allow radio communication between the mobile terminal 100 and a wireless communication system or network. For example, the wireless communication unit may include at least one of a mobile communication module 111, a wireless internet module 112, and a short-range wireless communication module 113.

The a/V input unit 120 is used to receive an audio or video signal. The a/V input unit 120 may include a camera 121 and a microphone 122, and the camera 121 processes image data of still pictures or video obtained by an image capturing apparatus in a video capturing mode or an image capturing mode. The processed image frames may be displayed on the display unit 151. The image frames processed by the cameras 121 may be stored in the memory 160 (or other storage medium) or transmitted via the wireless communication unit 110, and two or more cameras 121 may be provided according to the construction of the mobile terminal. The microphone 122 may receive sounds (audio data) via the microphone in a phone call mode, a recording mode, a voice recognition mode, or the like, and can process such sounds into audio data. The processed audio (voice) data may be converted into a format output transmittable to a mobile communication base station via the mobile communication module 112 in case of a phone call mode. The microphone 122 may implement various types of noise cancellation (or suppression) algorithms to cancel (or suppress) noise or interference generated in the course of receiving and transmitting audio signals.

The user input unit 130 may generate key input data according to a command input by a user to control various operations of the mobile terminal. The user input unit 130 allows a user to input various types of information, and may include a keyboard, dome sheet, touch pad (e.g., a touch-sensitive member that detects changes in resistance, pressure, capacitance, and the like due to being touched), scroll wheel, joystick, and the like. In particular, when the touch pad is superimposed on the display unit 151 in the form of a layer, a touch screen may be formed.

The sensing unit 140 detects a current state of the mobile terminal 100 (e.g., an open or closed state of the mobile terminal 100), a position of the mobile terminal 100, presence or absence of contact (i.e., touch input) by a user with the mobile terminal 100, an orientation of the mobile terminal 100, acceleration or deceleration movement and direction of the mobile terminal 100, and the like, and generates a command or signal for controlling an operation of the mobile terminal 100. For example, when the mobile terminal 100 is implemented as a slide-type mobile phone, the sensing unit 140 may sense whether the slide-type phone is opened or closed. In addition, the sensing unit 140 can detect whether the power supply unit 190 supplies power or whether the interface unit 170 is coupled with an external device.

The interface unit 170 serves as an interface through which at least one external device is connected to the mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device having an identification module, an audio input/output (I/O) port, a video I/O port, an earphone port, and the like. The identification module may store various information for authenticating a user using the mobile terminal 100 and may include a User Identity Module (UIM), a Subscriber Identity Module (SIM), a Universal Subscriber Identity Module (USIM), and the like. 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. Various command signals or power input from the cradle may be used as signals for recognizing whether the mobile terminal is accurately mounted on the cradle. The output unit 150 is configured to provide output signals (e.g., audio signals, video signals, alarm signals, vibration signals, etc.) in a visual, audio, and/or tactile manner. The output unit 150 may include a display unit 151, an audio output module 152, and the like.

The display unit 151 may display information processed in the mobile terminal 100. For example, when the mobile terminal 100 is in a phone call mode, the display unit 151 may display a User Interface (UI) or a Graphical User Interface (GUI) related to a call or other communication (e.g., text messaging, multimedia file downloading, etc.). When the mobile terminal 100 is in a video call mode or an image capturing mode, the display unit 151 may display a captured image and/or a received image, a UI or GUI displaying a video or an image and related functions, and the like.

Specifically, as shown in fig. 2, the display unit 151 is formed by a pixel array, and includes a first type pixel 1511 and a second type pixel 1512, where the first type pixel 1511 includes an infrared sensing diode for sensing light, an infrared light emitting diode for emitting infrared light, and a light emitting diode (e.g., RGB light emitting diode) for displaying color; the second type of pixels 1512 includes light emitting diodes (e.g., RGB light emitting diodes) for displaying colors, infrared light emitting diodes, but does not include infrared sensing diodes. Therefore, the display unit 151 can display colors through the first type of pixels and/or sense light and display colors through the second type of pixels. When the ir sensor diode in the first type of pixel is exposed to light (including ambient light, and infrared rays emitted by the ir led and reflected by external objects), it will generate an induced current, or an induced voltage, or charge, according to the intensity of the induced light. Accordingly, various beneficial operations can be performed according to the sensing result of each ir sensor diode in the display unit 151, including but not limited to adjusting the display brightness by sensing ambient light, detecting the surface profile of an object by sensing reflected light, identifying the position of the object by sensing ambient light or reflected light, and the like.

The audio output module 152 may convert audio data received by the wireless communication unit 110 or stored in the memory 160 into an audio signal and output as sound when the mobile terminal is in a call signal reception mode, a call mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Also, the audio output module 152 may provide audio output related to a specific function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output module 152 may include a speaker, a buzzer, and the like.

The memory 160 may store a software program or the like for processing and controlling operations performed by the controller 180, for example, may store a software program implementing the identity authentication method of the present invention, or may temporarily store data (e.g., a phonebook, messages, still images, videos, and the like) that has been output or is to be output. Also, the memory 160 may store data regarding various ways of vibration and audio signals output when a touch is applied to the touch screen.

The memory 160 may include at least one type of storage medium including a flash memory, a hard disk, a multimedia card, a card-type memory (e.g., SD or DX memory, etc.), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, an optical disk, and the like. Also, the mobile terminal 100 may cooperate with a network storage device that performs a storage function of the memory 160 through a network connection.

The controller 180 generally controls the overall operation of the mobile terminal. For example, the controller 180 performs control and processing related to voice calls, data communications, video calls, and the like. The controller 180 may perform a pattern recognition process to recognize a handwriting input or a picture drawing input performed on the touch screen as a character or an image.

The power supply unit 190 receives external power or internal power and provides appropriate power required to operate various elements and components under the control of the controller 180.

The various embodiments described herein may be implemented in a computer-readable medium using, for example, computer software, hardware, or any combination thereof.

Up to this point, mobile terminals have been described in terms of their functionality. 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.

Based on the above hardware structure of the mobile terminal, the present invention provides various embodiments of the privacy function executing apparatus.

The private function executing device in the present invention includes a mobile phone, a PAD or a PC side, and the present invention is preferably a mobile phone, and hereinafter, the details will be described by taking a mobile phone as an example.

Referring to fig. 3, fig. 3 is a block diagram of a private function performing apparatus according to a first embodiment of the present invention.

It is emphasized that the block diagram of FIG. 3 is merely an exemplary diagram of a preferred embodiment for those skilled in the art, and those skilled in the art can easily add new blocks around the blocks of the private function performing apparatus shown in FIG. 3; the names of the modules are self-defined names which are only used for assisting in understanding the program function blocks of the private function executing device and are not used for limiting the technical scheme of the invention, and the core of the technical scheme of the invention is the functions which are achieved by the modules with the respective defined names.

This embodiment provides a private function final controlling element, is applied to mobile terminal, mobile terminal's display screen includes infrared emitting diode and the infrared sensing diode that the array was arranged, infrared emitting diode is used for the emission infrared ray, infrared sensing diode is used for sensing the infrared ray, private function final controlling element includes:

the control module 10 is used for controlling the infrared light emitting diode to enter an emission mode and controlling the infrared sensing diode to enter an induction mode;

the determining module 20 is configured to determine sensing parameters corresponding to each infrared sensing diode sensing infrared rays when the infrared sensing diode senses that infrared rays emitted by the infrared light emitting diode are reflected by a finger of a user;

and the executing module 30 is configured to execute the private function corresponding to the determined sensing parameter based on a preset mapping relationship between the sensing parameter and the private function.

In this embodiment, the privacy function executing apparatus is implemented based on the mobile terminal shown in fig. 1 and 2, and the main scheme is as follows: the method is realized by utilizing infrared light-emitting diodes and infrared sensing diodes (the infrared light-emitting diodes and the infrared sensing diodes are all micro diodes, and the size of the micro diodes is only 1-20 micrometers) which are arranged in an array manner in a display screen of the mobile terminal. Firstly, infrared rays are emitted by the infrared light emitting diodes, and after the infrared rays are reflected by fingers of a user, the infrared rays reflected by the fingers of the user are sensed by the infrared sensing diodes, so that the execution of a private function is realized according to sensing parameters of the infrared sensing diodes. In an embodiment, the infrared light emitting diodes and the infrared sensing diodes are arranged in a manner as shown in fig. 4, one row of the infrared sensing diodes is arranged between two rows of the infrared light emitting diodes, that is, the infrared light emitting diodes and the infrared sensing diodes are arranged in a crossed manner, so that the row of the infrared sensing diodes can sense infrared rays reflected by an external object and emitted by adjacent rows of the infrared light emitting diodes.

In this embodiment, the implementation of the control module 10 includes:

A. the method comprises the steps that after the mobile terminal completes starting initialization, an infrared light emitting diode in a display screen of the mobile terminal is immediately controlled to enter an emission mode, and an infrared induction diode in the display screen of the mobile terminal is controlled to enter an induction mode; the infrared ray reflected by the finger of the user can be sensed in real time through the infrared sensing diode.

B. And in the second mode, the infrared light emitting diode in the display screen of the mobile terminal is controlled to enter an emission mode and the infrared sensing diode in the display screen of the mobile terminal is controlled to enter an induction mode after the terminal screen is awakened according to actual needs.

Wherein, in the second mode: the display screen of the mobile terminal is provided with a pressure sensor, when a user touches the terminal screen, the mobile terminal can detect the touch operation of the user through the pressure sensor, and then controls the infrared light-emitting diode to enter an emission mode and controls the infrared sensing diode to enter a sensing mode based on the detected touch operation.

For example, when a user touches a display screen of the mobile terminal to wake up, a fingerprint identification request is triggered, and then the mobile terminal identifies that fingerprint identification is required at present, controls an infrared light emitting diode in the display screen of the mobile terminal to enter an emission mode, and controls an infrared sensing diode in the display screen of the mobile terminal to enter an induction mode.

Through the control process, the infrared light-emitting diode in the display screen of the mobile terminal always works in the emission mode and emits infrared rays outwards, so that the infrared light-emitting diode in the display screen of the mobile terminal always works in the induction mode and induces external light (including ambient light and infrared rays reflected by the infrared light-emitting diode and reflected by an external object).

In this embodiment, the step of controlling the infrared light emitting diode to enter the emission mode and the step of controlling the infrared sensing diode to enter the sensing mode by the control module 10 "specifically includes: forward biased infrared light emitting diodes, reverse biased or zero biased infrared sensing diodes. That is, in a particular embodiment, the infrared light emitting diode is forward biased to cause the infrared light emitting diode to enter an emission mode, and the infrared light emitting diode is forward biased to cause the infrared light emitting diode to enter a sensing mode. It will be appreciated that although the infrared light emitting diode emits infrared light outwardly, it does not have any adverse effect on the user experience because the infrared light is not visible to the human eye.

In this embodiment, the area where the user's finger inputs the touch operation on the terminal screen is not limited, and may be any position on the terminal screen.

In this embodiment, after sensing the infrared rays reflected by the finger of the user through the infrared sensing diodes, the determining module 20 determines sensing references of the infrared sensing diodes sensing the infrared rays, wherein the sensing references include a finger sensing duration, a sensing time point and a sensing position.

It should be understood that before the infrared rays reflected by the user's finger are sensed by the infrared sensing diode, fingerprint information of the user's finger can be acquired according to the sensing result of the infrared sensing diode. Referring to fig. 5, when a user places a finger on a screen of the mobile terminal, due to the blocking of the finger, part of infrared rays emitted by the infrared light emitting diode are reflected and finally sensed by the infrared sensing diode. It should be noted that the finger fingerprint is formed by the protrusions and the grooves on the surface of the finger of the user, and when the infrared rays irradiate the protrusions and the grooves on the finger, the quantity and the angle of the reflected infrared rays are different, so that the infrared sensing diodes sense different quantities and angles of the incident infrared rays (and the infrared rays reflected back by the finger of the user), and the generated sensing results are different, thereby realizing the mapping of the finger fingerprint of the user through the sensing results of the infrared sensing diodes.

In addition, the infrared sensing diode generates an induced current or an induced voltage with different intensities according to the difference of the intensity of the induced infrared rays when the infrared sensing diode senses the infrared rays, and therefore, the step of acquiring the fingerprint information of the finger of the user according to the sensing result of the infrared sensing diode comprises the following steps:

step C, generating a bitmap corresponding to the fingerprint outline of the user finger according to induced current or induced voltage generated by each infrared induction diode sensing the light intensity of the infrared ray;

and D, acquiring fingerprint information of the finger of the user from the bitmap corresponding to the fingerprint outline of the finger of the user.

That is, in this embodiment, when acquiring the fingerprint information of the finger of the user, the bitmap corresponding to the fingerprint profile of the finger of the user can be generated according to the induced current or induced voltage generated when each infrared sensing diode senses the intensity of the infrared light, and the fingerprint information of the finger of the user is extracted from the bitmap corresponding to the fingerprint profile of the finger of the user.

In a specific implementation, taking a display screen of the mobile terminal as an example, 900 infrared sensing diodes are transversely arranged, and 1600 infrared sensing diodes are longitudinally arranged, and scanning sensing results of each row of infrared sensing diodes line by line, taking an induced voltage as an example, and when scanning an induced voltage of one infrared sensing diode, converting the induced voltage into an induced gray value of the infrared sensing diode according to a preset conversion rule (the setting of the conversion rule is not particularly limited, and can be set by a person skilled in the art according to actual needs), where S is a gray value, V is an upper integer, and k is a conversion coefficient, and a specific empirical value k is 0.75 obtained through specific experiments according to different performances of the infrared sensing diodes. For example, when the induced voltage of an ir-sensing diode is 300 mv, the induced voltage value is converted into the induced gray-scale value of the ir-sensing diode 300 + 0.75 + 225; for another example, when the induced voltage of an ir-sensing diode is 250 mv, the induced voltage value is converted into an induced gray-scale value of the ir-sensing diode, which is set to be 250 + 0.75 + 188. Thus, after the scanning of each infrared sensing diode is completed, the sensing voltage of each infrared sensing diode is converted into a gray scale value in the range of 0-255, and a bitmap with a resolution of 1600 × 900 is obtained, which includes the fingerprint profile of the user's finger, as shown in fig. 6. After obtaining the bitmap corresponding to the fingerprint outline of the user finger, the fingerprint information of the user finger can be extracted from the bitmap.

On the other hand, because the position of the infrared sensing diode on the display screen is fixed, the position of the finger of the user relative to the display screen is the position of the infrared sensing diode which senses the fingerprint of the finger of the user relative to the display screen, when fingerprint information is extracted from a bitmap corresponding to the fingerprint outline of the finger of the user, the position of the infrared sensing diode which senses the fingerprint of the finger of the user relative to the display screen can be determined according to the mapping relation between each pixel point in the bitmap and the infrared sensing diode, and then the position of the finger of the user relative to the display screen is determined.

Optionally, in other embodiments, the sensing result of each infrared sensing diode may be represented in other forms besides a bitmap, and the embodiments of the present invention are not limited in particular.

After acquiring the fingerprint information of the finger of the user according to the sensing result of each infrared sensing diode, the determining module 20 determines the sensing duration, the sensing time point and the sensing position of each infrared sensing diode. The sensing time duration refers to the time duration that the infrared sensing diode continuously senses the infrared ray reflected by the finger of the user; the sensing time point is the starting time point of the infrared sensing diode sensing the infrared rays reflected by the finger of the user; the sensing position refers to position information of the infrared sensing diode sensing the infrared ray. After the sensing duration, the sensing time point and the sensing position of each infrared sensing diode are determined, the executing module 30 can execute the private function corresponding to the determined sensing parameter according to the mapping relationship between the preset sensing parameter and the private function, and the specific executing mode is described in detail below.

The private function executing device provided by this embodiment controls the infrared light emitting diode to enter the emission mode, controls the infrared sensing diode to enter the sensing mode, determines sensing parameters corresponding to each infrared sensing diode sensing infrared rays when the infrared sensing diode senses that the infrared rays emitted by the infrared light emitting diode are reflected by a finger of a user, and finally executes a private function corresponding to the determined sensing parameters based on a mapping relationship between preset sensing parameters and the private function. In the scheme, the execution of the private function can be realized only through the induction parameters corresponding to the infrared induction diodes, the private function does not need to be executed by clicking for many times in an interface, and the convenience of executing the private function is improved.

Further, a second embodiment of the privacy function performing apparatus of the present invention is proposed.

The second embodiment of the privacy function performing apparatus is different from the first embodiment of the privacy function performing apparatus in that the executing module 30 includes:

In this embodiment, after each of the infrared sensing diodes senses infrared rays, the determining unit first determines a sensing time when each of the infrared sensing diodes senses infrared rays, and it should be understood that when a finger of a user touches the display screen, if only a specific position is clicked or pressed, then the times when the infrared sensing diodes sense infrared rays corresponding to the specific position are substantially consistent, and even if there is a time difference, the time difference is very small. Therefore, in this embodiment, when the time difference between the infrared sensing diodes sensing the infrared ray is smaller than the preset time period, which indicates that the user is only clicking or pressing currently, the determining unit further determines the position information of each infrared sensing diode. Wherein the preset time period is not limited, and is set according to the actual situation, such as setting to 0.1S,

after the position information of each infrared sensing diode is determined, the determining unit compares the specific coordinates corresponding to the determined position information with the coordinates of each icon in the current display interface to determine the icon matched with the position information. When the position information is matched with the position of the icon in the current display interface, the position that the user clicks or presses by the finger is the icon, at this moment, the determining unit further determines whether the duration of the infrared rays sensed by the infrared sensing diodes meets the preset duration, and if the preset duration is met, namely the duration of the icon pressed by the user reaches the preset duration, the executing unit can execute the private function corresponding to the icon in the current display interface. In this embodiment, the privacy function corresponding to the icon is set in advance, and the specific setting is set according to an actual situation. For example, the icon is an icon of a payment application, and the preset private function corresponding to the icon is to pop up a payment code, so that the payment code can be directly popped up when the icon is pressed for a long time.

For better understanding of the present embodiment, the exemplary application scenarios are as follows:

referring to fig. 7, when infrared rays reflected by a finger of a user are detected at a position of an icon in a current display interface through infrared sensing diodes, whether duration of the infrared rays sensed by the infrared sensing diodes meets a preset duration is determined, if the preset duration is met, a privacy function corresponding to the icon in the display interface is executed, and if the current icon is a 'pay treasure' icon and the privacy function is a pop-up payment code, after the 'pay treasure' icon is clicked, the push-up payment code can be popped up when the pressing duration reaches the preset duration.

It should be noted that, at present, options presented by the pressure key or the long-press icon are shortcut operation items, such as a payment application, and if options such as a payment code appear for a long time, a user wants to view the payment code and then jump. In the embodiment, when the user presses the icon in the display interface for a long time, the preset private function of the icon can be directly executed, so that the convenience of executing the private function is improved.

Further, in this embodiment, in order to improve the security of executing the private function, before the execution unit "executes the private function corresponding to the icon in the display interface", fingerprint information is also verified, specifically, the fingerprint information is compared with a pre-stored fingerprint, and after the fingerprint information is successfully verified, the execution unit executes the private function corresponding to the icon in the display interface.

Further, a third embodiment of the privacy function performing apparatus of the present invention is proposed.

The third embodiment of the privacy function performing apparatus is different from the second embodiment of the privacy function performing apparatus in that the performing unit is further configured to perform a privacy function corresponding to an application interface when the location information matches a preset fingerprint input area in the application interface and the fingerprint information matches pre-stored fingerprint information.

In this embodiment, the current application interface is preferably an interface requiring a fingerprint or password, such as a red envelope or payment interface.

The method comprises the steps that infrared rays are sensed through infrared sensing diodes in a current application interface, after position information of the infrared sensing diodes is determined because the time difference of the infrared sensing diodes sensing the infrared rays is smaller than a preset time period, if the position information of the infrared sensing diodes is detected to be a preset fingerprint input area in the application interface, fingerprint information acquired by the infrared sensing diodes is compared with a prestored fingerprint to determine whether the acquired fingerprint information is matched with the prestored fingerprint, and when the fingerprint information is matched with the prestored fingerprint information, a private function corresponding to the application interface can be executed by an execution unit. For example, a red packet or payment is made directly in the display interface according to the fingerprint information received in the preset fingerprint input area.

It should be noted that, in the conventional red package or payment, the user needs to click a confirmation button for confirmation or payment and then pop up the fingerprint input interface. In the embodiment, the confirmation button is replaced by the fingerprint and confirmed function button directly, the function button in the interface has a fingerprint indication, when a user presses a finger on the function button, the confirmation and fingerprint verification operations are directly executed, if the fingerprint is correct, the operation is directly finished, the user does not need to jump to the fingerprint input interface again, operation steps are saved, and the convenience is higher.

Further, a fourth embodiment of the privacy function performing apparatus of the present invention is proposed.

The fourth embodiment of the privacy function performing device is also different from the second embodiment of the privacy function performing device in that,

the determining unit is further configured to determine the sequence of the sensing time of each infrared sensing diode if the time difference between the infrared sensing diodes sensing infrared rays exceeds a preset time period; determining a sliding track of a finger of a user based on the sequence of the induction time of each infrared induction diode and the position information of each infrared induction diode;

In this embodiment, after the sensing time when each of the infrared sensing diodes senses infrared rays is determined, if the time difference when each of the infrared sensing diodes senses infrared rays exceeds a preset time period, it is indicated that a user does not input fingerprint information at a fixed position in a display screen, and may slide a finger for a period of fingerprint information, at this time, the determining unit determines the sensing time when each of the infrared sensing diodes senses infrared rays, and then determines a sequence based on each sensing time, and finally the executing unit determines a sliding track of the finger of the user based on the sequence of the sensing time of each of the infrared sensing diodes and the position information of each of the infrared sensing diodes.

It can be understood that when the finger slides to input a distance, the time that different infrared sensing diodes sense infrared rays is different, and then the sliding track of the finger of the user can be determined according to the sequence of the sensing time of each infrared sensing diode and the position information of each infrared sensing diode, that is, the distance from the infrared sensing diode which senses infrared rays first to the infrared sensing diode which senses infrared rays later is the sliding track of the finger of the user.

After the sliding track of the finger of the user is determined, the execution unit may execute the privacy function corresponding to the sliding track based on the sliding track. The corresponding relationship between the sliding track and the private function may be set in advance according to actual conditions, and is not limited here.

referring to fig. 8, in the current display interface, infrared rays are sensed through the infrared sensing diode in the area below the display screen, and the time points of the induction of each infrared induction diode in the lower area are different, at the moment, the sequence of the induction time of each infrared induction diode is firstly determined, then determining the sliding track of the finger of the user based on the sequence of the induction time of each infrared induction diode and the position information of each infrared induction diode, as shown in fig. 8, the infrared sensing diodes closer to the bottom in the lower area sense infrared rays earlier, and the infrared sensing diodes farther from the bottom sense infrared rays later, it is known that the sliding track slides from bottom to top, as shown in fig. 8, Q is the starting point of the sliding track, and P is the end point of the sliding track, at this time, the privacy function corresponding to the sliding track can be popped up. For example, the privacy function corresponding to the current sliding track is to pop up a payment code, or to open a privacy blog, etc.

It should be noted that, in this embodiment, the starting point and the ending point of the sliding track are not limited, and may be sliding from the bottom to the top of the terminal screen, or sliding from the top to the bottom of the terminal screen, or sliding from left to right, or sliding from right to left, which is specifically set according to the actual situation.

In this embodiment, in the display interface, according to the sliding track of the sliding operation, the corresponding private function is executed, so that the execution mode of the private function is more flexible, convenient and intelligent.

The invention also provides a private function execution method.

Referring to fig. 9, fig. 9 is a flowchart illustrating a method for executing a privacy function according to a first embodiment of the present invention.

The embodiment provides a private function execution method, which is applied to a mobile terminal, wherein a display screen of the mobile terminal comprises infrared light emitting diodes and infrared sensing diodes which are arranged in an array, the infrared light emitting diodes are used for emitting infrared rays, the infrared sensing diodes are used for sensing the infrared rays, and the private function execution method comprises the following steps:

step S10, controlling the infrared light emitting diode to enter a transmitting mode, and controlling the infrared sensing diode to enter a sensing mode;

step S20, when the infrared sensing diodes sense that the infrared rays emitted by the infrared light emitting diodes are reflected by the fingers of the user, determining sensing parameters corresponding to the infrared sensing diodes sensing the infrared rays;

and step S30, executing the private function corresponding to the determined induction parameter based on the preset mapping relation between the induction parameter and the private function.

In this embodiment, the method for executing the private function is implemented based on the mobile terminal shown in fig. 1 and 2, and the main scheme is as follows: the method is realized by utilizing infrared light-emitting diodes and infrared sensing diodes (the infrared light-emitting diodes and the infrared sensing diodes are all micro diodes, and the size of the micro diodes is only 1-20 micrometers) which are arranged in an array manner in a display screen of the mobile terminal. Firstly, infrared rays are emitted by the infrared light emitting diodes, and after the infrared rays are reflected by fingers of a user, the infrared rays reflected by the fingers of the user are sensed by the infrared sensing diodes, so that the execution of a private function is realized according to sensing parameters of the infrared sensing diodes. In an embodiment, the infrared light emitting diodes and the infrared sensing diodes are arranged in a manner as shown in fig. 4, one row of the infrared sensing diodes is arranged between two rows of the infrared light emitting diodes, that is, the infrared light emitting diodes and the infrared sensing diodes are arranged in a crossed manner, so that the row of the infrared sensing diodes can sense infrared rays reflected by an external object and emitted by adjacent rows of the infrared light emitting diodes.

In this embodiment, the implementation manner of step S10 includes:

In this embodiment, the step of "controlling the infrared light emitting diode to enter the emission mode and controlling the infrared sensing diode to enter the sensing mode" specifically includes: forward biased infrared light emitting diodes, reverse biased or zero biased infrared sensing diodes. That is, in a particular embodiment, the infrared light emitting diode is forward biased to cause the infrared light emitting diode to enter an emission mode, and the infrared light emitting diode is forward biased to cause the infrared light emitting diode to enter a sensing mode. It will be appreciated that although the infrared light emitting diode emits infrared light outwardly, it does not have any adverse effect on the user experience because the infrared light is not visible to the human eye.

In this embodiment, after sensing infrared rays reflected by a finger of a user through the infrared sensing diodes, a sensing reference of each infrared sensing diode sensing the infrared rays is determined, wherein the sensing reference includes a finger sensing duration, a sensing time point and a sensing position.

After fingerprint information of a finger of a user is acquired according to the sensing result of each infrared sensing diode, the sensing time length, the sensing time point and the sensing position of each infrared sensing diode are determined. The sensing time duration refers to the time duration that the infrared sensing diode continuously senses the infrared ray reflected by the finger of the user; the sensing time point is the starting time point of the infrared sensing diode sensing the infrared rays reflected by the finger of the user; the sensing position refers to position information of the infrared sensing diode sensing the infrared ray. After the sensing duration, the sensing time point and the sensing position of each infrared sensing diode are determined, the private function corresponding to the determined sensing parameters can be executed according to the mapping relation between the preset sensing parameters and the private function, and the specific execution mode is detailed in the following.

The method for executing the private function provided by this embodiment includes controlling the infrared light emitting diode to enter an emission mode, controlling the infrared sensing diode to enter an induction mode, determining induction parameters corresponding to each infrared sensing diode that senses infrared rays when the infrared sensing diode senses that infrared rays emitted by the infrared light emitting diode are reflected by a finger of a user, and finally executing the private function corresponding to the determined induction parameters based on a mapping relationship between preset induction parameters and the private function. In the scheme, the execution of the private function can be realized only through the induction parameters corresponding to the infrared induction diodes, the private function does not need to be executed by clicking for many times in an interface, and the convenience of executing the private function is improved.

Further, a second embodiment of the privacy function executing method of the present invention is proposed.

The second embodiment of the privacy function performing method is different from the first embodiment of the privacy function performing method in that the step S30 includes:

step 1, determining the sensing time of each infrared sensing diode sensing infrared rays;

step 2, if the time difference of the infrared sensing diodes sensing the infrared rays is smaller than a preset time period, determining the position information of each infrared sensing diode;

step 3, when the position information is matched with the position of the icon in the display interface, determining whether the duration of the infrared ray sensed by each infrared sensing diode meets the preset duration;

and 4, if the preset duration is met, executing a private function corresponding to the icon in the display interface.

In this embodiment, after each of the infrared sensing diodes senses infrared rays, the sensing time of each of the infrared sensing diodes sensing infrared rays is determined, and it should be understood that when a finger of a user touches the display screen, if only a click touch or a press touch is performed on a specific position, the time of sensing infrared rays by each of the infrared sensing diodes corresponding to the specific position is substantially consistent, and even if there is a time difference, the time difference is very small. Therefore, in this embodiment, when the time difference between the infrared sensing diodes sensing the infrared ray is smaller than the preset time period, it indicates that the user is only clicking touch or pressing touch currently, and at this time, the position information of each infrared sensing diode is further determined. Wherein the preset time period is not limited, and is set according to the actual situation, such as setting to 0.1S,

after the position information of each infrared sensing diode is determined, comparing the specific coordinate corresponding to the determined position information with the coordinate of each icon in the current display interface to determine the icon matched with the position information. When the position information is matched with the position of the icon in the current display interface, it is indicated that the position clicked or pressed by the finger of the user is the icon, at this time, whether the duration of the infrared rays sensed by each infrared sensing diode meets the preset duration is further determined, and if the preset duration is met, namely the duration of the icon pressed by the user reaches the preset duration, the mobile terminal can execute the private function corresponding to the icon in the current display interface. In this embodiment, the privacy function corresponding to the icon is set in advance, and the specific setting is set according to an actual situation. For example, the icon is an icon of a payment application, and the preset private function corresponding to the icon is to pop up a payment code, so that the payment code can be directly popped up when the icon is pressed for a long time.

Further, in this embodiment, in order to improve the security of executing the private function, before the "executing the private function corresponding to the icon in the display interface", fingerprint information is also verified, specifically, the fingerprint information is compared with a pre-stored fingerprint, and after the fingerprint information is successfully verified, the private function corresponding to the icon in the display interface is executed.

Further, a third embodiment of the privacy function executing method of the present invention is proposed.

The third embodiment of the privacy function executing method is also different from the second embodiment of the privacy function executing method in that, after the step 2, the privacy function executing method further includes:

and step 5, when the position information is matched with a preset fingerprint input area in an application interface and the fingerprint information is matched with prestored fingerprint information, executing a privacy function corresponding to the application interface.

The method comprises the steps that infrared rays are sensed through infrared sensing diodes in a current application interface, and because the time difference of the infrared sensing diodes sensing the infrared rays is smaller than a preset time period, after position information of the infrared sensing diodes is determined, if the position information of the infrared sensing diodes is detected to be a preset fingerprint input area in the application interface, fingerprint information acquired by the infrared sensing diodes is compared with a prestored fingerprint to determine whether the acquired fingerprint information is matched with the prestored fingerprint, and when the fingerprint information is matched with the prestored fingerprint information, a privacy function corresponding to the application interface can be executed. For example, a red packet or payment is made directly in the display interface according to the fingerprint information received in the preset fingerprint input area.

Further, a fourth embodiment of the privacy function executing method of the present invention is proposed.

The fourth embodiment of the privacy function executing method is also different from the second embodiment of the privacy function executing method in that, after the step S31, the privacy function executing method further includes:

step 6, if the time difference of the infrared sensing diodes sensing the infrared ray exceeds a preset time period, determining the sequence of the sensing time of the infrared sensing diodes;

step 7, determining the sliding track of the finger of the user based on the sequence of the induction time of each infrared induction diode and the position information of each infrared induction diode;

and 8, executing a privacy function corresponding to the sliding track.

In this embodiment, after the sensing time when each of the infrared sensing diodes senses infrared rays is determined, if the time difference when each of the infrared sensing diodes senses infrared rays exceeds a preset time period, it is indicated that a user does not input fingerprint information at a fixed position in a display screen, and may slide a finger for a period of fingerprint information, at this time, the sensing time when each of the infrared sensing diodes senses infrared rays is determined, then a sequence is determined based on each sensing time, and finally a sliding track of the finger of the user is determined based on the sequence of the sensing time of each of the infrared sensing diodes and the position information of each of the infrared sensing diodes.

After the sliding track of the finger of the user is determined, the privacy function corresponding to the sliding track can be executed based on the sliding track. The corresponding relationship between the sliding track and the private function may be set in advance according to actual conditions, and is not limited here.
