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 screen movement provided by the embodiment of the application 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 player, an e-book reader, a personal computer, a Personal Digital Assistant (PDA), a smart watch, and the like. The specific form of the electronic device is not limited in this application.

The flexible display screen of the electronic device of the embodiment of the application can be telescopic. The retractable display screen may also be referred to as a scroll screen (or scroll screen) configuration. The state of the scroll screen generally includes three modes: and three screen adjusting modes of non-unfolding, partial unfolding and full unfolding. Based on the three modes, the display screen of the electronic device with the scroll screen also has a corresponding screen display area. This is described below in connection with the example of fig. 1.

FIG. 1 shows a schematic diagram of a screen display area according to an embodiment of the application. Taking the electronic device as an example of a terminal, for a scroll terminal, the area of the display screen of the terminal may include 3 states shown in fig. 1. In the state that the display screen of the scroll terminal is not unfolded, the exposed area of the terminal screen may be the display area 10 shown in (1) in fig. 1. In the partially unfolded state of the display screen of the scroll terminal, the exposed area of the terminal screen may be as shown in (2) of fig. 1 as a display area 11. The area of the display region 11 is larger than the area of the display region 10. In the fully unfolded state of the display screen of the scroll terminal, the exposed area of the terminal screen may be the display area 12 shown in (3) of fig. 1. The area of the display region 12 is larger than the area of the display region 11.

It is understood that the size of the fully extended display (such as the size of the display area 12) may depend on the product implementation, and the embodiment of the present application is not particularly limited.

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

It should also be understood that the scenario in fig. 1 is only an application scenario of the present application, which is not limited to the embodiment of the present application.

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

Fig. 2 is a schematic diagram showing a partial structure of a terminal having a retractable display screen. 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 capable of relative movement. The display area of the flexible display 23 can be changed by relative movement between the housing 21 and the housing 22. The relative movement between the housing 21 and the housing 22 can be achieved by providing a moving module (not shown in fig. 2).

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

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

It is understood that only some components of the terminal are shown in fig. 2, and the embodiments of the present application are not limited thereto. In fact, the terminal may also include other components, such as a camera. Optionally, a camera may also 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 a distance detection module in the terminal. The embodiment of the application does not limit the specific form of the distance detection module, 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. As 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 is understood that the example of the distance detection module is merely an exemplary description, and the embodiments of the present application are not limited thereto, and the distance detection module may also be another form of distance meter.

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

Alternatively, the distance detection module is described as a laser focusing module in fig. 2. Fig. 2 (2) shows a structural example diagram of the laser focusing module set in the terminal. As shown in (2) of fig. 2, a processor 4 (such as a CPU) of the terminal is provided in a substrate (or a motherboard). For example, the substrate may be a Printed Circuit Board (PCB). Processor 4 and connector 3 may be connected via 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 the embodiment of the application, as long as the moving distance of the display screen can be detected. For example, the laser focusing module 1 may be placed at a position close to the mobile module in the middle of the terminal through a Flexible Printed Circuit (FPC) 2. The light emitted by the laser focusing module 1 can be aligned with the moving module, and the emitted light is kept from being shielded by other objects.

The position of the mobile module is not particularly limited in the embodiment of the application. The mobile module can drive the display screen to move. The moving 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 motor-driven, that is, the driving device is moved by a motor-driven moving module.

As shown in (2) in fig. 2, the flexible circuit board 2 is connected with a connector 3, that is, the flexible circuit board 2 can be connected with a main board through the connector 3. The embodiment of the present application does not specifically limit the type of the connector 3. For example, the connector 3 connected to the flexible circuit board 2 may be a Board To Board (BTB) connector or a flip chip connector.

The VDD 7 is used for supplying power to the laser focusing module 1. VDD 7 is connected to the connector 3. The VDD 7 may be connected to a Power Management Unit (PMU) 5 to supply power to the laser focusing module 1.

The power management unit 5 may be replaced by another power supply platform or another power supply form, 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 regulator (LDO).

As shown in (2) in fig. 2, when the display screen of the terminal is not unfolded, a 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, a 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 housing 22 is B. It can be understood that when the display screen of the terminal is partially unfolded, the distance between the laser focusing module 1 and the frame of the housing 22 is between a and B.

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

The SDA path and the SCL path are two paths of the I2C bus, both of which are bidirectional I/O lines. For the SDA path, the CPU is connected with the connector through an I2C _ SDA pin; the connector is connected with the distance detection module through an I2C _ SDA _ BTB pin. For an SCL path, the CPU is connected with the connector through an 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 for interrupt event processing. For an INT interrupt path, a CPU is connected with a connector through an INT pin; the connector is connected with the distance detection module through an INT _ BTB pin.

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

VDD is the power supply unit of the distance detection module, and as mentioned above, the power supply unit may be the aforementioned 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 diagram shown in (3) in fig. 2 is only an exemplary description, and the embodiments of the present application are not limited thereto. Other connection diagrams can also be obtained by a person skilled in the art based on the above-described principle. And if the distance detection module adopts different forms, a 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 partial pin line, and the embodiments of the present application are not limited thereto.

According to the technical scheme, the distance measurement module measures the distance in real time to obtain the distance parameter, and judges whether the distance parameter meets a first preset condition or not to control whether the display screen moves or not, and the screen moving state of the rolling screen electronic equipment can be effectively controlled.

The configuration shown in fig. 3 is not intended to specifically limit the electronic device 100. In other embodiments of the present application, electronic device 100 may include more or fewer components than shown in FIG. 3, or electronic device 100 may include a combination of some of the components shown in FIG. 3, or electronic device 100 may include sub-components of some of the components shown in FIG. 3. 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.

Processor 110 may include one or more processing units. For example, the processor 110 may include at least one of the following processing units: an Application Processor (AP), a modem processor, a Graphics Processing Unit (GPU), an Image Signal Processor (ISP), a controller, a video codec, a Digital Signal Processor (DSP), a baseband processor, and a neural Network Processor (NPU). The different processing units may be independent devices or integrated devices.

The controller can generate an operation control signal according to the instruction operation code and the timing signal to complete the control of instruction fetching and instruction execution.

A memory may also be provided in 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 have just been used or recycled by the processor 110. If the processor 110 needs to reuse the instruction or data, it can be called directly from the memory. Avoiding repeated accesses reduces the latency of the processor 110, thereby increasing the efficiency of the system.

The connection relationship between the modules shown in fig. 3 is only illustrative and does not limit the connection relationship between the modules of the electronic apparatus 100. Alternatively, the modules of the electronic device 100 may also adopt a combination of the connection manners in the above embodiments.

The electronic device 100 may implement display functionality through the GPU, the display screen 194, and the application processor. The GPU is a microprocessor for image processing, and is connected to the display screen 194 and an application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering.

The electronic device 100 may implement a photographing function through the ISP, the camera 193, the video codec, the GPU, the display screen 194, the application processor, and the like.

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

The camera 193 is used to capture still images or video. The object generates an optical image through the lens and projects the optical image to the photosensitive element. The photosensitive element may be a Charge Coupled Device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The light sensing element converts the optical signal into an electrical signal, which is then passed to the ISP where it is converted into a digital image signal. And 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, or the like format image signal. In some embodiments, the electronic device 100 may include 1 or N cameras 193, N being a positive integer greater than 1.

The digital signal processor is used for processing digital signals, and can process digital image signals and other digital signals. For example, when the electronic device 100 selects a frequency bin, the digital signal processor is used to perform fourier transform or the like on the frequency bin energy.

The electronic device 100 may implement audio functions, such as music playing and recording, through the audio module 170, the speaker 170A, the receiver 170B, the microphone 170C, the earphone interface 170D, and the application processor.

The audio module 170 is used to convert digital audio information into an analog audio signal for output, and may also be used to convert an analog audio input into a digital audio signal. The audio module 170 may also be used to encode and decode audio signals. In some embodiments, the audio module 170 or some functional modules of the audio module 170 may be disposed in the processor 110.

The speaker 170A, also called a horn, is used to convert the audio electrical signal into a sound signal. The electronic apparatus 100 can listen to music or a handsfree call through the speaker 170A.

The receiver 170B, also called an earpiece, is used to convert the electrical audio signal into a sound signal. When the user answers a call or voice information using the electronic apparatus 100, the voice can be answered by placing the receiver 170B close to the ear.

The microphone 170C, also referred to as a microphone or microphone, is used to convert sound signals into electrical signals. When a user makes a call or sends voice information, a sound signal may be input into the microphone 170C by sounding near the microphone 170C.

The headset interface 170D may be the USB interface 130, or may be an open mobile electronic device 100 platform (OMTP) standard interface of 3.5mm, a cellular telecommunications industry association (cellular telecommunications industry association of the USA, CTIA) standard interface.

The pressure sensor 180A is used for sensing a pressure signal, and converting the pressure signal into an electrical signal. In some embodiments, the pressure sensor 180A may be disposed on the display screen 194. The pressure sensor 180A may be of a wide variety, and may be, for example, a resistive pressure sensor, an inductive pressure sensor, or a capacitive pressure sensor. The capacitive pressure sensor may be a sensor including at least two parallel plates having conductive materials, 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 is applied to the display screen 194, the electronic apparatus 100 detects the touch operation according to the pressure sensor 180A. The electronic apparatus 100 may also calculate the touched position from the detection signal of the pressure sensor 180A. In some embodiments, the touch operations that are applied to the same touch position but different touch operation intensities may correspond to different operation instructions. For example: when the touch operation with the touch operation intensity smaller than the first pressure threshold value acts on the short message application icon, executing an instruction for viewing the short message; and when the touch operation with the touch operation intensity larger than or equal to the first pressure threshold value acts on the short message application icon, executing an instruction of newly building the short message.

The gyro sensor 180B may be used to determine the motion attitude of the electronic device 100. In some embodiments, the angular velocity of electronic device 100 about three axes (i.e., the x-axis, y-axis, and z-axis) may be determined by gyroscope 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 a shake angle of the electronic device 100, calculates a distance to be compensated for by the lens module according to the shake angle, and allows the lens to counteract the shake of the electronic device 100 by a reverse movement, thereby achieving anti-shake. The gyro sensor 180B can also be used in scenes such as navigation and motion sensing games.

The air pressure sensor 180C is used to measure air pressure. In some embodiments, electronic device 100 calculates altitude, aiding in positioning and navigation, from barometric pressure values measured by barometric pressure sensor 180C.

The magnetic sensor 180D includes a hall sensor. The electronic device 100 may detect the opening and closing of the flip holster using the magnetic sensor 180D. In some embodiments, when the electronic device 100 is a flip phone, the electronic device 100 may detect the opening and closing of the flip according to the magnetic sensor 180D. The electronic device 100 can set the flip cover to be automatically unlocked according to the detected opening and closing state of the holster or the detected opening and closing state of the flip cover.

Acceleration sensor 180E may detect the magnitude of acceleration of electronic device 100 in various directions, typically the x-axis, y-axis, and z-axis. The magnitude and direction of gravity can be detected when the electronic device 100 is stationary. The acceleration sensor 180E may also be used to recognize the attitude of the electronic device 100 as an input parameter for applications such as horizontal and vertical screen switching and pedometers.

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 utilize the range sensor 180F to range for fast focus.

The proximity light sensor 180G may include, for example, a light-emitting diode (LED) and a photodetector, for example, a photodiode. The LED may be an infrared LED. The electronic apparatus 100 emits infrared light outward through the LED. The electronic device 100 detects infrared reflected light from nearby objects using a photodiode. When the reflected light is detected, the electronic device 100 may determine that an object is present nearby. When the reflected light is not detected, the electronic device 100 may determine that there is no object nearby. The electronic device 100 can detect whether the user holds the electronic device 100 close to the ear by using the proximity light sensor 180G, so as to automatically turn off the screen to save power. The proximity light sensor 180G may also be used for automatic unlocking and automatic screen locking in a holster mode or a pocket mode. It should be understood that the proximity light sensor 180G described in fig. 3 may be an optional component. In some scenarios, the proximity light may be detected with an ultrasonic sensor instead of the proximity light sensor 180G.

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

The motor 191 may generate vibrations. The motor 191 may be used for incoming call prompts as well as for touch feedback. The motor 191 may generate different vibration feedback effects for touch operations applied to different applications.

The notification manager may also manage notifications that appear on the screen in dialog windows, such as prompting for text messages in a status bar, sounding a prompt tone, vibrating the electronic device, and flashing an indicator light.

The Android Runtime comprises a core library and a virtual machine. The Android runtime is responsible for scheduling and managing an Android system.

The core library comprises two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.

It should be understood that the above describes the structure diagram of the electronic device by taking fig. 3 as an example, and the software architecture of the electronic device is described by way of example in fig. 4, and the embodiments of the present application are not limited thereto.

The method of screen movement according to the embodiment of the present application is described below 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 of 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 scenarios shown in fig. 1 and 2. As shown in fig. 5, the method 500 includes:

s501, a first instruction is detected, and 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. Wherein the forward direction may be understood as the direction in which the display screen is stretched. The reverse direction is understood to be the direction in which the display screen is retracted.

Optionally, as an embodiment, the first instruction is used to instruct the display screen to move, and specifically includes: the first instruction is used for instructing 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 (1) in fig. 1 or (2) in fig. 1 to the display area shown in (3) in fig. 1, the process of stretching the display screen is performed. In this embodiment, the first instruction may also be referred to as a stretch instruction.

Optionally, as an embodiment, the first instruction is used to instruct the display screen to move, and specifically includes: the first instruction is used for instructing the display screen to move towards the shrinking direction of the display screen, wherein the size of the shrunk display screen is smaller than that of the display screen before shrinking. 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 performed. 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 a hardware trigger and/or a software trigger, and the like, and this is not particularly limited in this embodiment of the present application.

In one implementation, the first command may be triggered by a user through 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 function 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 the movement of the moving module. For example, if 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, a distance parameter is obtained through a distance detection module, and the distance parameter is used for representing the moving distance of the display screen.

In one implementation, the distance detection module is a laser focus module. For example, the laser focusing module can be set as shown in (2) in fig. 2. For other implementation manners of the distance detection module, reference may be made to the foregoing description, and details are not described herein.

It is understood 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 module with the same function. For example, the laser focusing module can be used to detect the distance that the display screen moves, and then the laser focusing module can be replaced by a sensor for detecting the distance that the display screen moves.

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

The moving distance of the display screen specifically comprises: the relative distance between the initial position of the display screen and the current position of the display screen. Illustratively, if the display screen is subjected to stretching movement, the distance refers to the distance between the initial position of the display screen and the position of the display screen after stretching movement; if the display screen is subjected to contraction movement, 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 a moving distance of the display screen, or may indirectly represent the moving distance of the display screen, which is not specifically limited in this embodiment of the application. For example, the distance parameter may be a specific distance value, i.e. a distance that directly reflects the movement of the display screen. For another example, the distance parameter may record a position where the display screen is moved, and after the distance parameter is transmitted to the processor, the processor may calculate a distance that the display screen moves based on the distance parameter.

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

Alternatively, the distance detection module may be connected to the processor of the electronic device via a connector (e.g., the connection principle shown in (3) of fig. 2), so as to perform 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 embodiment of the present application does not specifically limit the detection timing of the distance detection module. 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 the distance moved by the display screen after the display screen moves. For another example, the distance detection module may detect the moving distance of the display screen in real time after detecting the first instruction.

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

The first preset condition is introduced to judge 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 distance parameter satisfying the first preset condition may include: the distance parameter is greater than a set threshold. For another example, the distance parameter satisfying the first preset condition may include: the distance parameter is smaller than a set threshold value.

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

It should be understood that the above description regarding the first preset condition is only an example description, and the embodiment of the present application is 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 obtained through the distance detection module, the moving distance of the display screen is obtained, and then whether the display screen moves or not is determined by judging whether the moving distance of the display screen meets a first preset condition or not. And if the distance parameter does not meet the first preset condition, controlling the display screen to stop moving. The method for screen movement can effectively control the screen movement state of the rolling screen electronic equipment.

For a scrolling electronic device, the display screen may move in a forward direction or a reverse direction based on the movement instruction. According to the embodiment of the application, the distance parameter can be acquired in real time in the moving process of the display screen, so that the reasonable movement of the display screen can be controlled. Detailed examples are described below.

Optionally, as an embodiment, the first instruction is used to instruct the display screen to move towards the direction of stretching of the display screen. 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 it is determined that the distance parameter is smaller than the first distance threshold, which indicates that the current display screen has not reached the state where the display screen is fully unfolded, the display screen may continue to be moved in the stretching direction, or in the 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, etc. The naming of the first instruction is not particularly limited in the embodiments of the present application.

Alternatively, the first distance threshold may be determined based on a fully expanded state of the display screen. When the display screen is completely unfolded, the distance between the initial position when the display screen is not unfolded and the position when the display screen is completely unfolded can be used as the value of the first distance threshold. In addition, in specific implementation, a gap between the distance detection module and a 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 is 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 above determination manner regarding the first distance threshold is only an exemplary description, and the embodiments of the present application are not particularly limited.

In another implementation, the first instruction is to instruct the display screen to move in a direction in which the display screen is retracted. 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 where the display screen is not expanded, the display screen may continue to be contracted and moved, and the display screen may be controlled to move toward the contracted direction, or move in the reverse 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, etc. The naming of the first instruction is not particularly limited in the embodiments of the present application.

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 a 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 is used as the second distance threshold. Or a gap between the distance detection module and a frame of the housing of the electronic device is used as the second distance threshold. For example, the second distance threshold may be the distance a shown in (2) of fig. 2.

It should be understood that the above determination manner regarding the second distance threshold is only an exemplary description, and the embodiments of the present application are not particularly limited.

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

Optionally, during the movement of the display screen, the method further includes:

The second instruction may be understood as a display screen stop movement instruction. It will be appreciated that the second instruction described above applies to either a screen stretching movement or a screen shrinking movement.

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

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

In one implementation, the second instruction may be user-activated via 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 to remove, can learn the size of display screen according to the distance that the display screen removed, then carry out corresponding adaptation for the content that the display screen shows through the software mode to obtain the display effect who is full of science and technology sense, promote the display effect who rolls up the screen.

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

step 1, judging whether a forward moving instruction is detected.

For example, the forward move instruction may correspond to the first instruction described above. The first instruction is specifically for instructing the display screen to move in a direction in which the display screen is stretched.

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

Specifically, after the forward movement instruction is detected, the distance parameter may be obtained by the distance detection module, and then further determination may be made based on the distance parameter.

And 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, executing the step 3; if the distance parameter is not less than the first distance threshold, step 9 is performed. For the description of the first distance threshold, reference may be made to the foregoing description, and for brevity, the description is not 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 step 3, moving the display screen forward. A positive movement is the aforementioned movement in the direction of the stretching of the display screen.

Step 4, determining whether a stop command (corresponding to the second command) is detected. The stop instruction is used for instructing 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 or not.

For example, the move backward instruction may correspond to the first instruction described above. The first instruction is specifically used for instructing the display screen to move towards the direction of contraction of the display screen.

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

Specifically, after the reverse movement instruction is detected, the distance parameter may be obtained by the distance detection module, and then further determination may be made based on the distance parameter.

And 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 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 power consumption of the terminal is saved.

And 7, reversely moving the display screen. The reverse movement is the aforementioned movement in the direction of the contraction of the display screen.

Step 8, determining whether a stop command (corresponding to the second command) is detected. The stop instruction is used for instructing 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 only for the understanding of those skilled in the art, and the embodiments of the present application are not limited thereto.

Therefore, the screen moving method provided by the application obtains the distance parameter through the distance detection module, and judges whether the distance parameter meets the first preset condition to determine whether the display screen moves, so that the screen moving state of the rolling screen electronic equipment can be effectively controlled.
