Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

The method for moving the screen can be applied to electronic equipment with a flexible display screen. The electronic device may be, for example, various terminal devices such as a mobile phone, a tablet computer, a multimedia playing device, an electronic book reader, a personal computer, a Personal Digital Assistant (PDA), a smart watch, etc. The present application is not limited to a specific form of electronic device.

The flexible display screen of the electronic device of the embodiments of the present application may be retractable. The retractable display screen may also be referred to as a scroll screen (or scroll screen) structure. The status of a scroll screen generally includes three modes: non-expansion, partial expansion and full expansion. Based on these three modes, the display screen of the electronic device with the roll screen also has a corresponding screen display area. Described below in connection with the example in fig. 1.

Fig. 1 shows a schematic view of a screen display area according to an embodiment of the present application. Taking the example where the electronic device is a terminal, for a roll screen terminal, the area of the terminal display may include the 3 states shown in fig. 1. The display screen of the roll screen terminal may be in a state of not being unfolded, and the exposed area of the terminal screen may be the display area 10 shown in (1) of fig. 1. The display screen of the roll screen terminal may be in a partially unfolded state, and the exposed area of the terminal screen may be the display area 11 shown in (2) of fig. 1. The area of the display area 11 is larger than the area of the display area 10. The display screen of the roll screen terminal may be in a fully unfolded state, and the exposed area of the terminal screen may be the display area 12 shown in (3) of fig. 1. The area of the display area 12 is larger than the area of the display area 11.

It will be appreciated that the size of the fully extended display (e.g., the size of the display area 12) may depend on the product implementation and embodiments of the present application are not particularly limited.

It should be understood that the display screen shown in fig. 1 is only exemplary in description in the undeployed, partially deployed, and fully deployed states, and embodiments of the present application are not limited thereto.

It should also be understood that the scenario in fig. 1 is only a schematic illustration of one application scenario of the present application, which is not limiting to the embodiments of the present application, and the present application is not limited thereto.

In this embodiment of the present application, for the above-mentioned scroll terminal, movement of the display screen may be implemented by setting a corresponding movement component, and a distance of movement of the display screen may be detected by a distance detection module. The following is a description of a part of the structure shown in fig. 2.

Fig. 2 shows a partial schematic structure of a terminal with a retractable display. As shown in fig. 2 (1), the terminal housing assembly 20 includes a housing 21 and a housing 22. The housing 21 and the housing 22 are relatively movable. The display area of the flexible display 23 can be changed by a relative movement between the housing 21 and the housing 22. The relative movement between the housing 21 and the housing 22 may be achieved by providing a movement module (not shown in fig. 2).

For example, the display area of the flexible display screen 23 may be in 3 states as shown in fig. 1.

The embodiment of the application does not limit the specific form of the mobile module. Alternatively, the mobile module may be implemented by a mechanical assembly. For example, the movable module can be a scroll structure, and the display screen can be driven to stretch or shrink by rotating the scroll structure. Alternatively, the movement of the moving module may be implemented by a driving structure, for example, the moving module is driven by a stepping motor.

It will be appreciated that only some of the components of the terminal are shown in fig. 2, and embodiments of the present application are not limited thereto. In fact, the terminal may also comprise other components, such as a camera. Alternatively, a camera may be provided in the housing assembly 20.

In the embodiment of the application, the distance of the movement of the display screen is detected by arranging the distance detection module in the terminal. The specific form of the distance detection module is not limited, and only the distance of the movement of the display screen can be detected. For example, the distance detection module may be a laser focusing module. For another example, the distance detection module may be an infrared distance detector. For another example, the distance detection module may be an acoustic distance detection sensor. For another example, the distance detection module may be a displacement sensor. It will be appreciated that the examples herein with respect to the distance detection module are merely exemplary, and embodiments of the application are not limited thereto, as the distance detection module may be other forms of rangefinder.

Taking a laser focusing module as an example, the working principle of the laser focusing module is as follows: the distance from the target surface to the laser focusing module is calculated by emitting infrared light to the target surface and measuring the time difference of the reflected light.

Alternatively, fig. 2 illustrates an example in which the distance detection module is a laser focusing module. Fig. 2 (2) is a diagram showing one configuration example in which the laser focusing module is provided in the terminal. As shown in fig. 2 (2), a processor 4 (e.g., CPU) of the terminal is provided in a substrate (or motherboard). For example, the substrate may be a printed circuit board (printed circuit board, PCB). The processor 4 and the connector 3 may be connected via an I2C bus 6. The laser focusing module 1 can realize data transmission through the connector 3 and the processor 4.

The setting position of the laser focusing module 1 is not particularly limited in this embodiment, as long as the distance of the display screen movement can be detected. For example, the laser focusing module 1 can be placed in the middle of the whole machine of the terminal at a position close to the mobile module through a flexible circuit board (flexible printed circuit, FPC) 2. The light emitted by the laser focusing module 1 can be aligned with the moving module and can be kept from being blocked by other objects.

The position where the mobile module is disposed is not particularly limited in the embodiment of the present application. The mobile module can drive the display screen to move. The mobile module can move through the driving device. The drive means may be in the form of software and/or hardware. For example, the driving device may be a motor driving, that is, the moving module is driven by the motor to move.

As shown in (2) of fig. 2, the flexible circuit board 2 is connected with the connector 3, that is, the flexible circuit board 2 can be connected with the motherboard through the connector 3. The type of the connector 3 is not particularly limited in the embodiment of the present application. For example, the connector 3 connected to the flexible circuit board 2 may be a Board To Board (BTB) connector or a dome connector.

VDD 7 is used to power the laser focusing module 1. VDD 7 is connected to connector 3. VDD 7 may be connected to a power management unit (power management unit, PMU) 5 to power the laser focusing module 1.

The power management unit 5 may be replaced by other power supply platforms or other power supply forms, and the embodiment of the present application is not limited thereto. For example, the laser focusing module 1 is powered by an external low dropout linear regulator (low dropout regulator, LDO).

As shown in fig. 2 (2), when the display screen of the terminal is not unfolded, the distance between the laser focusing module 1 and the frame of the housing 22 is a, which can also be understood as that when the display screen is at the initial position, the gap between the laser focusing module 1 and the frame of the housing 22 is a; when the display screen of the terminal is completely unfolded, the distance between the laser focusing module 1 and the frame of the shell 22 is B. It will be appreciated that the distance between the laser focusing module 1 and the bezel of the housing 22 is between a and B when the display screen portion of the terminal is unfolded.

Fig. 2 (3) shows a schematic diagram of the connection of the distance detection module to the CPU. As shown in fig. 2 (3), the distance detection module (e.g., the laser focusing module 1) performs data transmission with the CPU (e.g., the processor 4) through the connector (e.g., the connector 3). The distance detection module and the CPU comprise an INT interrupt path, an EN enable path, a serial data line (SDA) path, a serial clock line (Serial clock line, SCL) path and the like.

The SDA path and the SCL path are two paths of the I2C bus, both being bi-directional I/O lines. For the SDA path, the CPU and the connector are connected through an I2C_SDA pin; the connector is connected with the distance detection module through an I2C_SDA_BTB pin. For SCL path, CPU and connector are connected by I2C_SCL pin; the connector is connected with the distance detection module through an I2C_SCL_BTB pin.

The INT interrupt path is sent to the CPU by the distance detection module to process interrupt event. For the INT interrupt path, the CPU and the connector are connected through an INT pin; the connector is connected with the distance detection module through an INT_BTB pin.

The EN enabling path is sent out by the CPU, and enables the distance detection module to work. For the EN enabling path, the CPU and the connector are connected through an EN pin; the connector is connected with the distance detection module through an EN_BTB pin.

VDD is a power supply unit of the distance detection module, and as described above, the power supply unit may be the power management unit 5 or other external LDO. The connector is connected with the distance detection module through a VDD_BTB pin.

GND is the ground terminal. The connector is connected with the distance detection module through a GND_BTB pin.

It should be understood that the connection schematic shown in fig. 2 (3) is only an exemplary description, and the embodiments of the present application are not limited thereto. Other connection diagrams may also be obtained by those skilled in the art based on the above principles. And if the distance detection module adopts different forms, the person skilled in the art can make corresponding reasonable connection to the connection principle based on the form of the distance detection module.

It should also be understood that the connection schematic diagram shown in fig. 2 (3) is only a part of the lead wires, and the embodiment of the present application is not limited thereto.

According to the technical scheme, the distance detection module measures the distance in real time to acquire the distance parameter, and judges whether the distance parameter meets the first preset condition or not to control whether the display screen moves or not, so that the screen movement state of the screen scrolling electronic device can be effectively controlled.

For example, the proximity light sensor 180G shown in fig. 3 may be optional. The components shown in fig. 3 may be implemented in hardware, software, or a combination of software and hardware.

A memory may also be provided in the processor 110 for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory may hold instructions or data that the processor 110 has just used or recycled. If the processor 110 needs to reuse the instruction or data, it can be called directly from the memory.

The connection relationship between the modules shown in fig. 3 is merely illustrative, and does not limit the connection relationship between the modules of the electronic device 100. Alternatively, the modules of the electronic device 100 may also use a combination of the various connection manners in the foregoing embodiments.

The electronic device 100 may implement display functions through a GPU, a display screen 194, and an application processor.

The ISP is used to process data fed back by the camera 193. For example, when photographing, the shutter is opened, light is transmitted to the camera photosensitive element through the lens, the optical signal is converted into an electric signal, and the camera photosensitive element transmits the electric signal to the ISP for processing and is converted into an image visible to naked eyes. The ISP can carry out algorithm optimization on noise, brightness and color of the image, and can optimize parameters such as exposure, color temperature and the like of a shooting scene. In some embodiments, the ISP may be provided in the camera 193.

The photosensitive element may be a charge coupled device (charge coupled device, CCD) or a Complementary Metal Oxide Semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, which is then transferred to the ISP to be converted into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into a standard Red Green Blue (RGB), YUV, etc. format image signal. In some embodiments, electronic device 100 may include 1 or N cameras 193, N being a positive integer greater than 1.

In some embodiments, the pressure sensor 180A may be disposed on the display screen 194. The pressure sensor 180A may be of various types, such as a resistive pressure sensor, an inductive pressure sensor, or a capacitive pressure sensor. The capacitive pressure sensor may be a device comprising at least two parallel plates with conductive material, and when a force is applied to the pressure sensor 180A, the capacitance between the electrodes changes, and the electronic device 100 determines the strength of the pressure based on the change in capacitance. When a touch operation acts on the display screen 194, the electronic apparatus 100 detects the touch operation according to the pressure sensor 180A. The electronic device 100 may also calculate the location of the touch based on the detection signal of the pressure sensor 180A. In some embodiments, touch operations that act on the same touch location, but at different touch operation strengths, may correspond to different operation instructions. For example: executing an instruction for checking the short message when the touch operation with the touch operation intensity smaller than the first pressure threshold acts on the short message application icon; and executing the instruction of newly creating the short message when the touch operation with the touch operation intensity being larger than or equal to the first pressure threshold acts on the short message application icon.

The gyro sensor 180B may be used to determine a motion gesture of the electronic device 100. In some embodiments, the angular velocity of electronic device 100 about three axes (i.e., x-axis, y-axis, and z-axis) may be determined by gyro sensor 180B. The gyro sensor 180B may be used for photographing anti-shake. For example, when the shutter is pressed, the gyro sensor 180B detects the shake angle of the electronic device 100, calculates the distance to be compensated by the lens module according to the angle, and makes the lens counteract the shake of the electronic device 100 through the reverse motion, so as to realize anti-shake. The gyro sensor 180B can also be used for scenes such as navigation and motion sensing games.

In some embodiments, when the electronic device 100 is a flip machine, the electronic device 100 may detect the opening and closing of the flip according to the magnetic sensor 180D. The electronic device 100 may set the characteristics of automatic unlocking of the flip cover according to the detected open-close state of the leather sheath or the open-close state of the flip cover.

The acceleration sensor 180E may detect the magnitude of acceleration of the electronic device 100 in various directions (typically, x-axis, y-axis, and z-axis). The magnitude and direction of gravity may be detected when the electronic device 100 is stationary. The acceleration sensor 180E may also be used to recognize the gesture of the electronic device 100 as an input parameter for applications such as landscape switching and pedometer.

The distance sensor 180F is used to measure a distance. The electronic device 100 may measure the distance by infrared or laser. In some embodiments, for example, in a shooting scene, the electronic device 100 may range using the distance sensor 180F to achieve fast focus.

When the reflected light is detected, the electronic device 100 may determine that an object is present nearby. When no reflected light is detected, the electronic device 100 may determine that there is no object nearby. The electronic device 100 can use the proximity light sensor 180G to detect whether the user holds the electronic device 100 close to the ear for talking, so as to automatically extinguish the screen for power saving. The proximity light sensor 180G may also be used for automatic unlocking and automatic screen locking in holster mode or pocket mode. It should be appreciated that the proximity light sensor 180G described in fig. 3 may be an optional component. In some scenarios, an ultrasonic sensor may be utilized in place of proximity sensor 180G to detect proximity light.

The ambient light sensor 180L is used to sense ambient light level. The electronic device 100 may adaptively adjust the brightness of the display 194 based on the perceived ambient light level. The ambient light sensor 180L may also be used to automatically adjust white balance when taking a photograph. Ambient light sensor 180L may also cooperate with proximity light sensor 180G to detect whether electronic device 100 is in a pocket to prevent false touches. In some embodiments, ambient light information of the terminal may be detected by ambient light sensor 180L.

It should be understood that, the foregoing is an illustration of a block diagram of an electronic device by taking fig. 3 as an example, and the software architecture of the electronic device is illustrated by fig. 4, which is not limited thereto.

The following describes a method of screen movement according to an embodiment of the present application with reference to fig. 5 to 6.

Referring to fig. 5, fig. 5 shows a schematic flow chart of a method 500 of screen movement according to an embodiment of the present application. The method 500 is applied to an electronic device having a retractable display screen. The electronic device includes a distance detection module. It is to be appreciated that the method 500 is applicable to the scenario illustrated in fig. 1 and 2. As shown in fig. 5, the method 500 includes:

s501, detecting a first instruction, wherein the first instruction is used for indicating the display screen to move.

The first instruction may instruct the retractable display of the electronic device to move in a forward direction or instruct the retractable display of the electronic device to move in a reverse direction. The forward direction is understood to mean the direction in which the display screen stretches. The reverse direction is understood to be the direction in which the display screen is contracted.

Optionally, as an embodiment, the first instruction is configured to instruct the display to move, and specifically includes: the first instruction is used for indicating the display screen to move towards the stretching direction of the display screen, wherein the size of the stretched display screen is larger than that of the display screen before stretching. For example, when the display area of the display screen changes from the area shown in fig. 1 (1) or fig. 1 (2) to the display area shown in fig. 1 (3), the process of stretching the display screen is the process. In this embodiment, the first instruction may also be referred to as a stretch instruction.

Optionally, as an embodiment, the first instruction is configured to instruct the display to move, and specifically includes: the first instruction is used for indicating the display screen to move towards the shrinkage direction of the display screen, wherein the size of the display screen after shrinkage is smaller than that of the display screen before shrinkage. For example, when the display area of the display screen changes from the area shown in (2) in fig. 1 to the area shown in (1) in fig. 1, the process of shrinking the display screen is the process. In this embodiment, the first instruction may also be referred to as a shrink instruction.

The triggering form of the first instruction may be various, including but not limited to hardware triggering and/or software triggering, and the embodiment of the application is not limited in particular.

In one implementation, the first instruction may be user-actuated by a key. For example, a function key may be provided on the electronic device, and the first instruction is triggered when the user presses the key.

In another implementation, the first instruction may be triggered by a user operating a control in the electronic device. For example, clicking on a control in an application.

Alternatively, the first instruction may be an instruction for controlling movement of the mobile module. For example, assuming that the mobile module is driven by a motor, the first command may be a Pulse Width Modulation (PWM) signal for controlling the rotation of the motor.

S502, obtaining a distance parameter through a distance detection module, wherein the distance parameter is used for representing the moving distance of the display screen.

In one implementation, the distance detection module is a laser focusing module. For example, the setting position of the laser focusing module may be as shown in fig. 2 (2). Other implementations of the distance detection module may refer to the foregoing descriptions, and are not described herein.

It will be appreciated that the laser focusing module is only exemplary and the present application is not limited thereto. The laser focusing module can also be replaced by a sensor or a module with the same function. For example, the laser focusing module may be used to detect the distance moved by the display screen, and then the laser focusing module may be replaced with a sensor for detecting the distance moved by the display screen.

Specifically, the distance moved by the display screen can be measured by the distance detection module. The distance the display moves includes the distance the display stretches, or the distance the display contracts.

The distance that the display screen moves specifically includes: the relative distance between the initial position of the display screen and the current position of the display screen. For example, if the display screen is stretched, the distance refers to the distance between the initial position of the display screen and the position of the display screen after the stretching; if the display screen is contracted, the distance refers to the distance between the initial position of the display screen and the position of the display screen after the contraction movement.

It can be understood that the distance parameter may directly represent the distance that the display screen moves, or may indirectly represent the distance that the display screen moves, which is not specifically limited in the embodiment of the present application. For example, the distance parameter may be a specific distance value, i.e. a distance directly reflecting the movement of the display screen. For another example, the distance parameter may record a position of the display screen after moving, and when the distance parameter is transmitted to the processor, the processor may calculate a distance of the display screen moving based on the distance parameter.

Optionally, the distance detection module may transmit a distance parameter (including distance data) to the processor of the electronic device after measuring the distance moved by the display screen, so that the processor may further analyze the distance parameter.

Alternatively, the distance detection module may be connected to the processor of the electronic device through a connector (for example, a connection principle as shown in (3) of fig. 2) for data transmission.

In one implementation, the distance detection module transmits the distance parameter to a processor of the electronic device via an I2C bus.

The detection timing of the distance detection module is not particularly limited in the embodiment of the application. For example, the distance detection module may detect the distance moved by the display screen in real time. For another example, the distance detection module may detect a distance moved by the display screen after the display screen is moved. For another example, the distance detection module may detect the moving distance of the display screen in real time after detecting the first instruction.

S503, determining whether the distance parameter meets a first preset condition.

The first preset condition is introduced for determining whether the display screen can be moved based on the distance parameter.

Alternatively, the first preset condition may be determined by a distance threshold. There may be different situations where the distance parameter satisfies the first preset condition based on the specific content indicated by the first instruction.

For example, the satisfaction of the distance parameter to the first preset condition may include: the distance parameter is greater than a set threshold. For another example, the satisfaction of the distance parameter with the first preset condition may include: the distance parameter is less than a set threshold.

For another example, the satisfaction of the distance parameter with the first preset condition may include: the distance parameter is located in a certain distance interval.

It should be understood that the above description about the first preset condition is only an exemplary description, and the embodiments of the present application are not limited thereto.

S504, responding to the first instruction, and controlling the display screen to move when the distance parameter meets a first preset condition; and when the distance parameter does not meet the first preset condition, controlling the display screen to stop moving.

In the embodiment of the application, the distance parameter is acquired through the distance detection module, the distance of the movement of the display screen is obtained, and then whether the display screen moves is determined by judging whether the distance of the movement of the display screen meets a first preset condition. And if the distance parameter meets the first preset condition, controlling the display screen to move, and if the distance parameter does not meet the first preset condition, controlling the display screen to stop moving. The screen movement method can effectively control the screen movement state of the screen scrolling electronic device.

For a roll screen electronic device, the display screen may be moved forward or backward based on movement instructions. According to the embodiment of the application, the distance parameters can be acquired in real time in the moving process of the display screen, so that reasonable movement of the display screen is controlled. Detailed embodiments are described below.

Optionally, as an embodiment, the first instruction is used to instruct the display to move towards the stretching direction of the display. At this time, the distance parameter satisfies a first preset condition, including: the distance parameter is less than a first distance threshold.

That is, if the distance parameter is determined to be smaller than the first distance threshold, which indicates that the current display screen has not reached the state in which the display screen is fully unfolded, the display screen may further move in a stretching manner, and then the display screen may be controlled to move in a stretching direction or in a forward direction.

It will be appreciated that in this embodiment, the first instruction may also be referred to as a forward move instruction, or a stretch instruction, or the like. The naming of the first instruction in the embodiment of the present application is not specifically limited.

Alternatively, the first distance threshold may be determined based on a fully extended state of the display screen. When the display screen is fully unfolded, the distance between the initial position of the display screen when the display screen is not unfolded and the position of the display screen when the display screen is fully unfolded can be used as the value of the first distance threshold. In addition, in the specific implementation, a gap between the distance detection module and the housing frame of the electronic device may be considered, and a distance between a position where the distance detection module is located when the display screen is in an initial state when the display screen is not unfolded and a position where the housing frame of the electronic device is located when the display screen is completely unfolded may be used as the first distance threshold. For example, the first distance threshold may be the distance B shown in (2) of fig. 2.

It should be understood that the manner in which the first distance threshold is determined is merely an exemplary description, and embodiments of the present application are not specifically limited.

In another implementation, the first instruction is for instructing the display to move in a direction in which the display is contracted. At this time, the distance parameter satisfies a first preset condition, including: the distance parameter is greater than a second distance threshold.

That is, if the distance parameter is determined to be greater than the second distance threshold, which indicates that the current display screen has not reached the state in which the display screen is not expanded, the display screen may further continue to shrink, and then the display screen may be controlled to move in the shrinking direction or move in the opposite direction.

It will be appreciated that in this embodiment, the first instruction may also be referred to as a reverse move instruction, or a shrink instruction, or the like. The naming of the first instruction in the embodiment of the present application is not specifically limited.

Alternatively, the second distance threshold may be determined based on an undeployed state of the display screen. For example, when the display screen is not unfolded, a gap between the distance detection module and the housing frame of the electronic device may be considered, and a distance between a position where the distance detection module is located when the display screen is in an initial state when the display screen is not unfolded and a position where the housing frame of the electronic device is located when the display screen is not unfolded may be used as the second distance threshold. Or a gap between the distance detection module and a shell frame of the electronic device is used as a second distance threshold value. For example, the second distance threshold may be the distance a shown in fig. 2 (2).

It should be appreciated that the manner in which the second distance threshold is determined is merely an exemplary description, and embodiments of the present application are not specifically limited.

In the moving process of the display screen, whether a stopping instruction is received or not can be detected in real time, so that the stopping operation behavior of the user on the display screen can be responded at any time.

Optionally, during the moving of the display screen, the method further comprises:

The second instruction may be understood as a display screen stop movement instruction. It will be appreciated that the second instruction described above applies whether the display screen is moved in tension or in contraction.

For example, when the display screen is moving in the stretching direction, if the second instruction is received, the display screen stops the stretching movement. When the display screen is moving towards the shrinking direction, if the second instruction is received, the display screen stops shrinking movement.

The triggering form of the second instruction may be various, including but not limited to hardware triggering and/or software triggering, and the embodiment of the application is not limited in particular.

In one implementation, the second instruction may be user-triggered by a key. For example, a key may be provided on the electronic device, and the second instruction is triggered when the user presses the key.

In another implementation, the second instruction may be triggered by a user operating a control in the electronic device. For example, clicking on a control in an application.

In this application embodiment, after the display screen stops moving, can learn the size of display screen according to the distance that the display screen moved, then carries out corresponding adaptation through the software mode for the content that the display screen shows to obtain the display effect that is full of technological sense, promote the display effect of rolling up the screen.

For ease of understanding, the following description is provided in connection with the logic flow in FIG. 6. As shown in fig. 6, includes:

and step 1, judging whether a forward movement instruction is detected.

For example, the forward move instruction may correspond to the first instruction of the foregoing. The first instruction is specifically used for indicating the display screen to move towards the stretching direction of the display screen.

If a forward movement instruction is detected, executing step 2; if no forward movement instruction is detected, step 9 is performed.

Specifically, after the forward movement instruction is detected, the distance parameter can be acquired through the distance detection module, and then further judgment is made based on the distance parameter.

And step 2, judging whether the distance parameter is smaller than a first distance threshold value.

If the distance parameter is smaller than the first distance threshold value, executing the step 3; if the distance parameter is not less than the first distance threshold, step 9 is performed. The description of the first distance threshold may refer to the foregoing, and for brevity, will not be repeated here. Therefore, when the first distance threshold is judged to be reached, the display screen can automatically stop moving, or automatically execute a stop instruction, so that invalid movement of the display screen is avoided, and the terminal power consumption is saved.

And 3, forward moving the display screen. Forward movement is the movement referred to above in the direction of stretching the display screen.

Step 4, judging whether a stop instruction (corresponding to the second instruction) is detected. The stop instruction is used for indicating the display screen to stop moving.

If a stop instruction is detected, executing step 9; if no stop instruction is detected, step 2 is performed.

And 5, judging whether a reverse movement instruction is detected.

For example, the reverse move instruction may correspond to the first instruction of the foregoing. The first instruction is specifically used for indicating the display screen to move towards the shrinkage direction of the display screen.

If a reverse movement instruction is detected, executing step 6; if no reverse movement instruction is detected, step 9 is performed.

Specifically, after the reverse movement instruction is detected, the distance parameter can be acquired through the distance detection module, and then further judgment is made based on the distance parameter.

And step 6, judging whether the distance parameter is larger than a second distance threshold value.

If the distance parameter is greater than the second distance threshold, executing step 7; if the distance parameter is not greater than the second distance threshold, step 9 is performed. Therefore, when the second distance threshold is judged to be reached, the display screen can automatically stop moving, or automatically execute a stop instruction, so that invalid movement of the display screen is avoided, and the terminal power consumption is saved.

And 7, reversely moving the display screen. Reverse movement is the aforementioned movement towards the display screen contraction.

Step 8, judging whether a stop instruction (corresponding to the second instruction). The stop instruction is used for indicating the display screen to stop moving. If a stop instruction is detected, executing step 9; if no stop instruction is detected, step 6 is performed.

And 9, stopping moving the display screen.

It should be understood that the specific flow shown in fig. 6 is merely for ease of understanding by those skilled in the art, and embodiments of the present application are not limited thereto.

According to the screen movement method, the distance parameter is obtained through the distance detection module, whether the distance parameter meets the first preset condition is judged, whether the display screen moves is determined, and the screen movement state of the screen scrolling electronic device can be effectively controlled.
