it should be noted that the target film region is at least a partial region of the flexible electrostrictive polymer film.
It should be noted that the flexible display screen 110 includes a touch surface (the touch surface is located outside the terminal and can be directly touched by a user) and a non-touch surface (the non-touch surface is located inside the terminal and cannot be touched by the user), that is, the first surface is a non-touch surface, the flexible electrostrictive polymer film 120 can be deformed under the action of an external electric field, as shown in fig. 2 to 4, which are different forms of the flexible electrostrictive polymer film 120 under the action of different external electric fields, respectively, fig. 2 is a schematic diagram of a state of the flexible electrostrictive polymer film 120 as a whole, fig. 3 is a schematic diagram of a state of local deformation of the surface of the flexible electrostrictive polymer film 120, and fig. 4 is a schematic diagram of a state of the flexible electrostrictive polymer film 120 as a whole; further, the electrode assembly 130 may be disposed on a side of the flexible electrostrictive polymer film 120 opposite to the flexible display screen 110, or may be disposed on a side of the flexible electrostrictive polymer film 120 opposite to the flexible display screen 110; in order to cause different deformations at different positions of the flexible electrostrictive polymer film 120, the electrode assembly 130 according to an embodiment of the present invention includes at least one electrode distributed in an array, the control voltage input to the different electrodes by the controller 140 is different, and the deformation modes of the regions of the flexible electrostrictive polymer film 120 corresponding to the different electrode positions are different.

As shown in fig. 5, an embodiment of the present invention further provides a screen control method applied to the terminal, including:
It should be noted that, according to the control instruction, the controller may search a preset voltage table for a control voltage corresponding to each electrode, and apply the control voltage to the electrode assembly, so that the flexible electrostrictive polymer film is deformed correspondingly, so as to change a friction force of the screen of the terminal in contact with the object.
Further, in order to facilitate the controller to determine and change the area of the flexible electrostrictive polymer film, the control instruction carries indication information for indicating the target screen area, and the controller determines the voltage of the electrode of the first film area of the flexible electrostrictive polymer film corresponding to the target screen area according to the indication information and outputs the voltage to the corresponding electrode, so as to realize the deformation of the first film area.
It should be noted that, after the target screen area is deformed, the target screen area includes at least one of the following items:
the target screen area forms at least one convex part;
the target screen area forms at least one recess.
That is, by forming a plurality of protrusions and/or depressions, the target screen area of the terminal is made uneven, and thus the frictional force between other objects and the screen of the terminal can be increased.
It should be noted that the screen deformation instruction is generated based on the capacitance variation of the screen or the acceleration of the terminal, and the specific implementation process of step 501 is described below from different generation manners of the screen deformation instruction.
Mode one, generating a screen deformation instruction based on the capacitance variation of a screen
Situation one,
The realization principle of the mode is as follows: because the terminal can gather the electric capacity on the screen in real time, when the screen of terminal does not contact with any object, can regard the electric capacity that the screen this moment has as original capacitance value (original capacitance value refers to the capacitance value of terminal screen under the state of not contacting user's finger), when external object (for example user's finger) contacts the screen, the electric capacity of screen can appear changing for original capacitance value, and touch the screen when user's finger is dry and user's finger is moist (namely there is water or sweat on the user's finger), the electric capacity variation of screen can also be inequality.
Applying the principle, the embodiment of the present invention realizes step 501 in a specific manner as follows: detecting the capacitance variation of the current capacitance value and the original capacitance value of each area of the flexible screen;
generating a screen deformation instruction under the condition that the capacitance variation of a first target area of the flexible display screen is detected to be within a first preset capacitance variation range;
it should be noted that, in this process, the screen area of the terminal needs to be divided, and the specific implementation manner may be: the screen is divided into a plurality of equal areas according to a preset area.
Further, after the user touches the screen with the finger, the capacitance of the screen area touched by the user finger changes, and the capacitance variation generated when the user touches the screen with the dry finger is different from that generated when the user touches the screen with the wet finger, specifically, the variation can be obtained by measuring experimental data, in this way, when the user determines that the wet finger touches the screen through experiments in advance, the capacitance variation range of the screen and the capacitance variation range of the dry finger touch the screen, at least one of the capacitance variation ranges of the screen, namely, the first preset capacitance variation range includes: at least one of the range of capacitance change of the screen when the wet finger contacts the screen and the range of capacitance change of the screen when the dry finger contacts the screen, and then whether the current capacitance value of each area of the screen and the capacitance change amount of the original capacitance value are within a first preset capacitance change range, if the current capacitance value and the capacitance change amount of the original capacitance value are within the first preset capacitance change range, it is indicated that the user is the screen contacted by the wet or dry finger, the risk of terminal sliding exists, at the moment, the anti-sliding of the terminal screen is needed, and a screen deformation instruction is generated.
Specifically, in this case, the first target area is determined as a target screen area to be deformed, that is, when screen deformation is performed, only a specific voltage needs to be applied to the electrodes on the electrode pattern corresponding to the first target area.
As shown in fig. 6, the specific implementation flow in this way is:
601, automatically detecting the capacitance variation of the current capacitance value and the original capacitance value of each area of the flexible screen by the terminal;
for example, when the first predetermined capacitance variation range includes only: the method comprises the following steps that when a wet finger touches a screen, the capacitance change range of the screen is mainly detected, whether a user finger of a touch terminal screen is in a wet state or not is detected, and if the capacitance change amount of a first target area is within a first preset capacitance change range, the user finger is in the wet state is indicated;
step 604, outputting a control instruction to the controller to deform a target screen area on the flexible display screen;
the screen is deformed to increase the friction between the screen and the finger contact surface, and for example, the preset screen area may be deformed into a wave shape, a concave-convex shape, or the like.
605, after the screen of the terminal is deformed, prompting the user that the terminal is in an anti-skid and anti-falling mode;
the specific prompting mode may be: and prompting the user by using voice or prompting the user by popping up a window on a screen to perform text prompting.
The embodiment of the invention can improve the possibility of sliding when the terminal is held by a user, and reduce the probability of damage and scratch caused by falling of the terminal.
In case two, the implementation principle of this way is: the user actively starts the anti-slip function, and in this case, as long as the user holds the terminal screen, the screen needs to be deformed to prevent the terminal from slipping off.
Applying the principle, the embodiment of the present invention realizes step 501 in a specific manner as follows: receiving a first input performed by a user; generating a screen morphing instruction in response to the first input.
It should be noted that the first input refers to an operation of starting the anti-skid function by the user, in this case, an anti-skid function on/off button is provided on the terminal, and the user can actively turn on or off the anti-skid function according to the use requirement.
Further, after the anti-skid function is started, a deformed screen area needs to be determined, and whether a user touches the screen needs to be acquired through the determination of the area, specifically, the implementation process is as follows:
acquiring the capacitance variation of the current capacitance value and the original capacitance value of each area of a terminal screen;
and if the capacitance variation of the second target area on the terminal screen meets a second preset capacitance variation range, determining the second target area as a preset screen area to be adjusted on the screen.
It should be noted that, the capacitance variation of the screen caused by the touch of the finger on the screen can be measured by experimental data, and this is achieved by determining the range of capacitance variation of the screen when the finger touches the screen, i.e., a second preset capacitance variation range including a capacitance variation range in which the user touches the screen with a dry finger and a capacitance variation range in which the user touches the screen with a wet finger, then, whether the capacitance variation of the current capacitance value and the original capacitance value of each area of the screen is within a second preset capacitance variation range or not is judged, if so, indicating that the user has touched the screen with a finger, at which point the area of the screen touched by the user's finger is available, when the screen is deformed, only a specific voltage needs to be applied to the electrodes on the electrode pattern corresponding to the screen area contacted by the finger of the user.
Mode two, the screen deformation instruction is generated according to the acceleration of the terminal
The realization principle of the mode is as follows: when the terminal is still and the screen is in contact with a still surface (the still surface refers to the plane which is still relative to the horizontal plane), in order to avoid the terminal sliding off the still plane, at this time, the deformation of the screen needs to be performed, specifically, the implementation process of step 501 is as follows:
acquiring an included angle between a screen of a terminal and a horizontal plane under the condition that the screen of the terminal is attached to a first plane of a target object;
acquiring the acceleration of the terminal under the condition that the included angle is not zero;
and generating a screen deformation instruction under the condition that the acceleration of the terminal is greater than a preset value.
It should be noted that the target object refers to an object placed on a horizontal plane, and the first plane refers to a stationary plane on the target object.
It should be noted that, the fact that the screen of the terminal is attached to the first plane of the target object means that the terminal is placed on the first plane, whether the terminal is placed on the first plane can be detected through an infrared sensor arranged on the terminal, and when the terminal is placed on the first plane, infrared rays emitted by the infrared sensor are reflected by the first plane, so that the infrared sensor can detect the emitted infrared rays; whether the terminal is buckled on the first plane or not can be detected through the ambient light sensor, the ambient light sensor can detect the intensity of ambient light usually only when the screen is exposed outside, and if the intensity of the ambient light detected by the ambient light sensor is smaller than or equal to a positive number close to zero, the screen of the surface terminal is buckled on the first plane; whether the terminal is buckled on the first plane or not can be detected through the gravity acceleration sensor, and if the terminal is placed positively, the direction of the gravity acceleration detected by the gravity acceleration sensor is positive, and when the screen of the terminal is attached to the static surface, the direction of the gravity acceleration detected by the gravity acceleration sensor of the terminal is negative, so that whether the screen of the terminal is buckled on the first plane or not can be judged.
The angle between the screen of the terminal and the horizontal plane can be measured by one of a gyroscope and an acceleration sensor.
It should be further noted that, when the terminal is stationary on a plane forming a preset angle with the horizontal plane, the terminal may have a fixed acceleration at this time, the acceleration in this state may be considered as a preset value (i.e., a preset value), and when the terminal receives an external force, an acceleration may be generated, at this time, the acceleration of the terminal may change, that is, the acceleration of the terminal may be greater than the preset value, at this time, deformation of the screen needs to be performed, that is, a screen deformation instruction is generated, so as to prevent the terminal from falling off the plane when a user touches the terminal inadvertently.
It should be noted that, in this case, the first area and the second area of the flexible display screen are determined as the target screen area to be adjusted;
wherein the convex height of the convex portion of the first region is greater than the convex height of the convex portion of the second region;
the center of gravity height of the terminal corresponding to the first area is lower than that of the terminal corresponding to the second area.
That is, when the terminal is placed on a plane inclined with respect to the horizontal plane, the protrusion height of the screen of a portion of the terminal close to the horizontal plane needs to be set higher than the protrusion height of the screen of a portion far from the horizontal plane, so as to reduce the included angle between the terminal and the horizontal plane as much as possible and avoid the terminal from sliding down.
As shown in fig. 7, the specific implementation flow in this way is:
701, acquiring the current acceleration of the terminal under the condition that a screen of the terminal is attached to a first plane of a target object and the included angle between the screen of the terminal and the horizontal plane is not zero;
step 704, outputting a control instruction to a controller to deform a target screen area on the flexible display screen;
the screen is deformed to increase the friction between the screen and the contact surface, and for example, the preset screen area may be deformed into a wave shape, a concave-convex shape, or the like.
Step 705, after the screen of the terminal is deformed, prompting the user that the terminal is in an anti-skid and anti-falling mode;
the specific prompting mode may be: and prompting the user by using voice or prompting the user by popping up a window on a screen to perform text prompting.
It should be noted that, in the embodiment of the present invention, the screen of the terminal is changed into a shape capable of increasing friction, so that the problem that the terminal is easy to slide down when the screen of the terminal contacts with an object can be avoided, thereby reducing the risk of damage to the terminal and prolonging the service life of the terminal.
