Description

Screen moving method and device

Technical Field

The present application relates to the field of terminal technology, and in particular, to a method and device for moving a screen.

Background technique

With the rapid development of smart terminals, the user experience of terminals has also improved. For smart terminals, having a large screen can significantly improve the user experience. Generally speaking, large-screen terminals are large in size and are not easy for users to carry.

The emergence of flexible screens has made it possible to develop portable large screens. Flexible screens include flexible organic light-emitting diodes (OLED) and other screen types. By applying flexible screens to smart terminals, smart terminals are more flexible and portable. At present, some manufacturers have applied flexible screens to mobile phones, such as scroll screen terminals. However, there is no effective solution for how to control the screen movement of scroll screen terminals.

Summary of the invention

In view of this, the present application provides a method, device, electronic device, computer-readable storage medium and computer program product for screen movement, which can effectively control the movement of the display screen and greatly improve the user experience of the roll-screen terminal.

In a first aspect, a method for moving a screen is provided, the method being applied to an electronic device, the electronic device having a retractable display screen, the electronic device including a distance detection module, the method comprising:

A first instruction is detected, where the first instruction is used to instruct the display screen to move;

Acquiring a distance parameter through the distance detection module, wherein the distance parameter is used to characterize the distance that the display screen moves;

Determining whether the distance parameter satisfies a first preset condition;

In response to the first instruction, when the distance parameter meets the first preset condition, controlling the display screen to move;

When the distance parameter does not meet the first preset condition, the display screen is controlled to stop moving.

The above method can be executed by a terminal device or a chip in the terminal device. Based on the above scheme, the distance parameter is obtained by the distance detection module to obtain the distance that the display screen moves, and then whether the display screen moves is determined by judging whether the distance the display screen moves meets the first preset condition. If the distance parameter meets the first preset condition, the display screen is controlled to move; if the distance parameter does not meet the first preset condition, the display screen is controlled to stop moving. The method for moving the screen in the embodiment of the present application can effectively control the screen movement state of the rolling screen electronic device.

In a possible implementation manner, during the movement of the display screen, the method further includes:

detecting a second instruction, wherein the second instruction is used to instruct the display screen to stop moving;

In response to the second instruction, the display screen is controlled to stop moving.

Therefore, during the movement of the display screen, it can also respond to the user's stop command to stop moving the display screen, thereby improving the user's control experience over the display screen.

In a possible implementation, the first instruction is used to instruct the display screen to move in a direction in which the display screen is stretched, wherein the size of the display screen after stretching is larger than the size of the display screen before stretching;

The distance parameter satisfies a first preset condition, including: the distance parameter is less than a first distance threshold;

Wherein, controlling the display screen to move includes: controlling the display screen to stretch.

Therefore, the first instruction controls the display screen to move in the stretching direction, or in other words, to move forward, thereby improving the user experience of scrolling. In addition, the first distance threshold can be used to constrain the stretching distance of the display screen to avoid invalid movement, which helps save power consumption.

In a possible implementation, the first instruction is used to instruct the display screen to move in a direction of shrinking the display screen, wherein the size of the display screen after shrinking is smaller than the size of the display screen before shrinking;

The distance parameter satisfies a first preset condition, including: the distance parameter is greater than a second distance threshold;

Wherein, controlling the display screen to move includes: controlling the display screen to shrink.

Therefore, the first instruction controls the display screen to move in the contraction direction, or in the reverse direction, thereby improving the user experience of scrolling. In addition, the second distance threshold can be used to constrain the contraction distance of the display screen to avoid invalid movement, which helps save power consumption.

In a possible implementation, the distance detection module is a laser focus module.

In a second aspect, a device for moving a screen is provided, comprising a unit for executing any one of the methods in the first aspect.

In a third aspect, an electronic device is provided, comprising: a retractable display screen, a distance detection module, and a processor;

Wherein, the processor is used to detect a first instruction, and the first instruction is used to instruct the display screen to move;

The distance detection module is used to detect a distance parameter, and the distance parameter is used to characterize the distance that the retractable display screen moves;

The processor is also used to determine whether the distance parameter satisfies a first preset condition; in response to the first instruction, control the display screen to move when the distance parameter satisfies the first preset condition; and control the display screen to stop moving when the distance parameter does not satisfy the first preset condition.

The flexible display screen of the electronic device of the embodiment of the present application may be retractable. The retractable display screen may also be referred to as a roll screen (or scroll screen) structure. The state of the roll screen generally includes three modes: three screen adjustment modes, namely, non-expanded, partially expanded, and fully expanded. Based on these three modes, the display screen of the electronic device with the roll screen also has a corresponding screen display area. The following is described in conjunction with the example in FIG. 1.

Taking the electronic device as a terminal as an example, for a rolling screen terminal, the area of the terminal display screen may include the three states shown in FIG1 . When the display screen of the rolling screen terminal is not unfolded, the exposed area of the terminal screen may be the display area 10 as shown in FIG1 (1). When the display screen of the rolling screen terminal is partially unfolded, the exposed area of the terminal screen may be the display area 11 as shown in FIG1 (2). The area of the display area 11 is larger than the area of the display area 10. When the display screen of the rolling screen terminal is fully unfolded, the exposed area of the terminal screen may be the display area 12 as shown in FIG1 (3). The area of the display area 12 is larger than the area of the display area 11.

It can be understood that the size of the fully unfolded display screen (such as the size of the display area 12) may depend on the product implementation and is not specifically limited in the embodiments of the present application.

It should be understood that the display screen shown in FIG. 1 in the non-expanded, partially expanded and fully expanded 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 Figure 1 is only a schematic illustration of an application scenario of the present application, which does not constitute a limitation on the embodiments of the present application, and the present application is not limited to this.

In the embodiment of the present application, for the above-mentioned rolling screen terminal, the movement of its display screen can be achieved by setting a corresponding moving component, and the distance of the display screen movement can be detected by a distance detection module. The following is a partial structural description in conjunction with FIG.

The housing 21 and the housing 22 can move relative to each other. The display area of the flexible display screen 23 can be changed by the 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 setting a moving module (not shown in FIG2).

For example, the display area of the flexible display screen 23 can be in three states as shown in FIG. 1 .

The embodiments of the present application do not limit the specific form of the mobile module. Optionally, the mobile module can be implemented by a mechanical component. For example, the mobile module can be a scroll structure, and the display screen can be stretched or retracted by rotating the scroll structure. Optionally, the movement of the mobile module can be achieved by a driving structure, for example, the mobile module is driven by a stepping motor.

It is understood that FIG. 2 only shows some components of the terminal, 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, the camera may also be disposed in the housing assembly 20.

In an embodiment of the present application, a distance detection module is provided in the terminal to detect the distance that the display screen moves. The embodiment of the present application does not limit the specific form of the distance detection module, as long as it can detect the distance that the display screen moves. For example, the distance detection module may be a laser focus 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 wave distance detection sensor. For another example, the distance detection module may be a displacement sensor. It can be understood that the examples of the distance detection module here are only exemplary descriptions, and the embodiments of the present application are not limited thereto, and the distance detection module may also be other forms of rangefinders.

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

Optionally, FIG2 describes the distance detection module as a laser focus module. FIG2 (2) shows a structural example diagram of a laser focus module set in a terminal. As shown in FIG2 (2), a processor 4 (such as a CPU) of the terminal is set in a substrate (or a mainboard). For example, the substrate can be a printed circuit board (PCB). The processor 4 and the connector 3 can be connected via an I2C bus 6. The laser focus module 1 can realize data transmission with the processor 4 via the connector 3.

The embodiment of the present application does not specifically limit the location of the laser focus module 1, as long as the distance of the display screen movement can be detected. For example, the laser focus module 1 can be placed in the middle of the terminal near the mobile module through a flexible printed circuit (FPC) 2. The light emitted by the laser focus module 1 can be aimed at the mobile module and the emitted light can be kept from being blocked by other objects.

The embodiment of the present application does not specifically limit the location of the mobile module. The mobile module can drive the display screen to move. The mobile module can be moved by a driving device. The driving device can be in the form of software and/or hardware. For example, the driving device can be a motor drive, that is, the mobile module is driven by a motor to move.

As shown in (2) of FIG. 2 , the flexible circuit board 2 is connected to the connector 3, that is, the flexible circuit board 2 can be connected to the mainboard 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 can be a board to board connector (board to board, BTB) or a spring-type connector.

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

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

As shown in (2) of FIG. 2 , when the display screen of the terminal is not unfolded, the distance between the laser focus module 1 and the frame of the housing 22 is A. It can also be understood that when the display screen is in the initial position, the gap between the laser focus module 1 and the frame of the housing 22 is A; when the display screen of the terminal is fully unfolded, the distance between the laser focus 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 focus module 1 and the frame of the housing 22 is between A and B.

FIG2 (3) shows a schematic diagram of the distance detection module connected to the CPU. As shown in FIG2 (3), the distance detection module (for example, the laser focus module 1) transmits data to the CPU (for example, the processor 4) through a connector (for example, 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, and a serial clock line (SCL) path.

For the SDA path, the CPU and the connector are connected through the I2C_SDA pin; the connector and the distance detection module are connected through the I2C_SDA_BTB pin. For the SCL path, the CPU and the connector are connected through the I2C_SCL pin; the connector and the distance detection module are connected through the I2C_SCL_BTB pin.

VDD is a power supply unit of the distance detection module. As mentioned above, the power supply unit may be the power management unit 5 or other external LDO. The connector is connected to the distance detection module via the VDD_BTB pin.

GND is the ground terminal. The connector and the distance detection module are connected through the GND_BTB pin.

It should be understood that the connection principle diagram shown in (3) of FIG. 2 is only an exemplary description, and the embodiments of the present application are not limited thereto. A person skilled in the art can also obtain other connection diagrams based on the above principles. Furthermore, if the distance detection module adopts a different form, a person skilled in the art can make a corresponding reasonable connection for the connection principle based on the form of the distance detection module.

It should be noted that the structure shown in FIG3 does not constitute a specific limitation on the electronic device 100. In other embodiments of the present application, the electronic device 100 may include more or fewer components than those shown in FIG3, or the electronic device 100 may include a combination of some of the components shown in FIG3, or the electronic device 100 may include sub-components of some of the components shown in FIG3. For example, the proximity light sensor 180G shown in FIG3 may be optional. The components shown in FIG3 may be implemented in hardware, software, or a combination of software and hardware.

The 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 processing unit (NPU). Different processing units may be independent devices or integrated devices.

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

The processor 110 may also be provided with a memory for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory may store instructions or data that the processor 110 has just used or cyclically used. If the processor 110 needs to use the instruction or data again, it may be directly called from the memory. This avoids repeated access, reduces the waiting time of the processor 110, and thus improves the efficiency of the system.

The connection relationship between the modules shown in Fig. 3 is only a schematic illustration and does not constitute a limitation on the connection relationship between the modules of the electronic device 100. Optionally, the modules of the electronic device 100 may also adopt a combination of multiple connection modes in the above embodiments.

The electronic device 100 can realize the display function through the GPU, the display screen 194 and the application processor. The GPU is a microprocessor for image processing, which connects the display screen 194 and the application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering. The processor 110 may include one or more GPUs, which execute program instructions to generate or change display information.

The display screen 194 can be used to display images or videos. The display screen 194 includes a display panel. The display panel can be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a mini light-emitting diode (Mini LED), a micro light-emitting diode (Micro LED), a micro OLED (Micro OLED) or a quantum dot light emitting diode (QLED). In some embodiments, the electronic device 100 may include 1 or N display screens 194, where N is a positive integer greater than 1. In an embodiment of the present application, the display screen 194 is a flexible display screen, or a retractable display screen, or a roll screen. In some embodiments, the unfolded state of the display screen 194 can be 3 states as shown in Figure 1.

The electronic device 100 can realize the shooting function through the ISP, the camera 193, the video codec, the GPU, the display screen 194 and the application processor.

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

The camera 193 is used to capture still images or videos. The object generates an optical image through the lens and projects it onto the photosensitive element. The photosensitive element can be a charge coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, and then passes the electrical signal to the ISP for conversion 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 an image signal in a standard red green blue (RGB), YUV or other format. In some embodiments, the electronic device 100 may include 1 or N cameras 193, where N is a positive integer greater than 1.

The digital signal processor is used to process digital signals, and can process not only digital image signals but also other digital signals. For example, when the electronic device 100 is selecting a frequency point, the digital signal processor is used to perform Fourier transform on the frequency point energy.

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

The audio module 170 is used to convert digital audio information into analog audio signal output, and can also be used to convert analog audio input into digital audio signals. The audio module 170 can 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 can be arranged in the processor 110.

The speaker 170A, also called a horn, is used to convert an audio electrical signal into a sound signal. The electronic device 100 can listen to music or make a hands-free call through the speaker 170A.

The receiver 170B, also called an earpiece, is used to convert an audio electrical signal into a sound signal. When a user uses the electronic device 100 to answer a call or voice message, the user can listen to the voice by placing the receiver 170B close to the ear.

Microphone 170C, also called a microphone or a speaker, is used to convert sound signals into electrical signals. When a user makes a call or sends a voice message, the user can input the sound signal into microphone 170C by speaking close to microphone 170C.

The earphone interface 170D is used to connect a wired earphone and can be a USB interface 130 or a 3.5 mm open mobile terminal platform (OMTP) standard interface or a cellular telecommunications industry association of the USA (CTIA) standard interface.

The pressure sensor 180A is used to sense the pressure signal and can convert the pressure signal into an electrical signal. In some embodiments, the pressure sensor 180A can be set on the display screen 194. There are many types of pressure sensors 180A, for example, they can be resistive pressure sensors, inductive pressure sensors or capacitive pressure sensors. The capacitive pressure sensor can be a parallel plate including at least two conductive materials. When the force acts on the pressure sensor 180A, the capacitance between the electrodes changes, and the electronic device 100 determines the intensity of the pressure according to the change in capacitance. When the touch operation acts on the display screen 194, the electronic device 100 detects the touch operation according to the pressure sensor 180A. The electronic device 100 can also calculate the position of the touch according to the detection signal of the pressure sensor 180A. In some embodiments, touch operations acting on the same touch position but with different touch operation intensities can correspond to different operation instructions. For example: when a touch operation with a touch operation intensity less than the first pressure threshold acts on a short message application icon, an instruction to view the short message is executed; when a touch operation with a touch operation intensity greater than or equal to the first pressure threshold acts on a short message application icon, an instruction to create a new short message is executed.

The gyro sensor 180B can be used to determine the motion posture of the electronic device 100. In some embodiments, the angular velocity of the electronic device 100 around three axes (i.e., the x-axis, the y-axis, and the z-axis) can be determined by the gyro sensor 180B. The gyro sensor 180B can be used for anti-shake shooting. For example, when the shutter is pressed, the gyro sensor 180B detects the angle of the electronic device 100 shaking, calculates the distance that the lens module needs to compensate based on the angle, and allows the lens to offset the shaking of the electronic device 100 through reverse movement to achieve anti-shake. The gyro sensor 180B can also be used in scenes such as navigation and somatosensory games.

The air pressure sensor 180C is used to measure air pressure. In some embodiments, the electronic device 100 calculates the altitude through the air pressure value measured by the air pressure sensor 180C to assist positioning and navigation.

The magnetic sensor 180D includes a Hall sensor. The electronic device 100 can use the magnetic sensor 180D to detect the opening and closing of the flip leather case. In some embodiments, when the electronic device 100 is a flip phone, the electronic device 100 can detect the opening and closing of the flip cover according to the magnetic sensor 180D. The electronic device 100 can set features such as automatic unlocking of the flip cover according to the detected opening and closing state of the leather case or the opening and closing state of the flip cover.

The acceleration sensor 180E can detect the magnitude of the acceleration of the electronic device 100 in various directions (generally the x-axis, y-axis and z-axis). When the electronic device 100 is stationary, the magnitude and direction of gravity can be detected. The acceleration sensor 180E can also be used to identify the posture 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 the distance. The electronic device 100 can measure the distance by infrared or laser. In some embodiments, for example, in a shooting scene, the electronic device 100 can use the distance sensor 180F to measure the distance to achieve fast focusing.

The proximity light sensor 180G may include, for example, a light-emitting diode (LED) and a light detector, such as a photodiode. The LED may be an infrared LED. The electronic device 100 emits infrared light outward through the LED. The electronic device 100 uses a photodiode to detect infrared reflected light from nearby objects. When the reflected light is detected, the electronic device 100 may determine that there is an object nearby. When the reflected light is not detected, the electronic device 100 may determine that there is no object nearby. The electronic device 100 may use the proximity light sensor 180G to detect whether the user holds the electronic device 100 close to the ear to talk, 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 lock 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, an ultrasonic sensor may be used to replace the proximity light sensor 180G to detect proximity light.

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

The fingerprint sensor 180H is used to collect fingerprints. The electronic device 100 can use the collected fingerprint characteristics to realize functions such as unlocking, accessing application locks, taking photos, and answering calls.

The touch sensor 180K is also called a touch control device. The touch sensor 180K can be set on the display screen 194. The touch sensor 180K and the display screen 194 form a touch screen, which is also called a touch control screen. The touch sensor 180K is used to detect touch operations acting on or near it. The touch sensor 180K can pass the detected touch operation to the application processor to determine the type of touch event. Visual output related to the touch operation can be provided through the display screen 194. In other embodiments, the touch sensor 180K can also be set on the surface of the electronic device 100 and set at a different position from the display screen 194.

The distance detection module 180N is used to detect the distance moved by the display screen 194. For example, the distance detection module 180N may be a laser focus module, and the relevant description thereof may refer to the description of FIG. 2 above.

The key 190 includes a power key and a volume key. The key 190 can be a mechanical key or a touch key. The electronic device 100 can receive a key input signal and implement a function related to the case input signal.

Motor 191 can generate vibration. Motor 191 can be used for incoming call reminders and can also be used for touch feedback. Motor 191 can generate different vibration feedback effects for touch operations acting on different applications. Motor 191 can also generate different vibration feedback effects for touch operations acting on different areas of display screen 194. Different application scenarios (for example, time reminders, receiving messages, alarm clocks, and games) can correspond to different vibration feedback effects. The touch vibration feedback effect can also support customization.

In some embodiments, the processor 110 is used to detect a first instruction, wherein the first instruction is used to instruct the display screen 194 to move; the processor 110 can obtain a distance parameter detected by the distance detection module 180N through a connector, wherein the distance parameter is used to characterize the distance over which the display screen 194 moves; the processor 110 is also used to determine whether the distance parameter satisfies a first preset condition; in response to the first instruction, when the distance parameter satisfies the first preset condition, the display screen 194 is controlled to move; when the distance parameter does not satisfy the first preset condition, the display screen 194 is controlled to stop moving.

The above describes in detail the hardware system of the electronic device 100, and the following describes the software system of the electronic device 100. The software system may adopt a layered architecture, an event-driven architecture, a micro-core architecture, a micro-service architecture, or a cloud architecture. The embodiment of the present application takes the layered architecture as an example to exemplarily describe the software system of the electronic device 100.

As shown in FIG4 , a software system using a layered architecture is divided into several layers, each layer has a clear role and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the software system can be divided into four layers, from top to bottom, namely, the application layer, the application framework layer, the Android runtime (Android Runtime) and the system library, and the kernel layer.

The application layer may include applications such as camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, short message, etc.

The application framework layer provides an application programming interface (API) and a programming framework for applications in the application layer. The application framework layer may include some predefined functions.

For example, the application framework layer includes the window manager, content provider, view system, telephony manager, resource manager, and notification manager.

The window manager is used to manage window programs. The window manager can obtain the display screen size, determine whether there is a status bar, lock the screen, and capture the screen.

Content providers are used to store and retrieve data and make it accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, and phone books.

The view system includes visual controls, such as controls for displaying text and controls for displaying images. The view system can be used to build applications. A display interface can be composed of one or more views. For example, a display interface including a text notification icon can include a view for displaying text and a view for displaying images.

The phone manager is used to provide communication functions of the electronic device 100, such as management of call status (connected or hung up).

The resource manager provides various resources for applications, such as localized strings, icons, images, layout files, and video files.

The notification manager enables applications to display notification information in the status bar. It can be used to convey notification-type messages and can disappear automatically after a short stay without user interaction. For example, the notification manager is used for download completion notifications and message reminders. The notification manager can also manage notifications that appear in the system's top status bar in the form of icons or scrolling bar text, such as notifications from applications running in the background. The notification manager can also manage notifications that appear on the screen in the form of dialog windows, such as prompting text messages in the status bar, emitting reminder sounds, vibrating electronic devices, and flashing indicator lights.

Android Runtime includes core libraries and virtual machines. Android runtime is responsible for scheduling and management of the Android system.

The core library consists of two parts: one part is the function that needs to be called by the Java language, and the other part is the Android core library.

The application layer and the application framework layer run in the virtual machine. The virtual machine executes the Java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection.

The system library can include multiple functional modules, such as: surface manager, media library, 3D graphics processing library (such as open graphics library for embedded systems (OpenGL ES)) and 2D graphics engine (such as skia graphics library (SGL)).

In some embodiments, the system library may further include a display screen movement decision module. The display screen movement decision module is used to determine whether the distance parameter meets a first preset condition; when the distance parameter meets the first preset condition, the display screen is controlled to move by the mobile module drive; when the distance parameter does not meet the first preset condition, the display screen is controlled to stop moving by the mobile module drive.

It should be understood that the display screen movement decision module can also be located in other layers in the figure, such as the application layer, the application framework layer, etc. The display screen movement decision module is located in the system library as an example for explanation here, and the embodiments of the present application are not limited to this.

The surface manager is used to manage the display subsystem and provide the fusion of 2D layers and 3D layers for multiple applications.

The media library supports playback and recording of multiple audio formats, playback and recording of multiple video formats, and still image files. The media library can support multiple audio and video coding formats, such as: MPEG4, H.264, moving picture experts group audio layer III (MP3), advanced audio coding (AAC), adaptive multi-rate (AMR), joint photographic experts group (JPG) and portable network graphics (PNG).

The 3D graphics processing library can be used to implement 3D graphics drawing, image rendering, compositing and layer processing.

A 2D graphics engine is a drawing engine for 2D drawings.

The kernel layer is the layer between hardware and software. The kernel layer can include driver modules such as display driver, camera driver, audio driver, sensor driver and distance detection driver.

In some embodiments, the core layer may further include a distance detection driver and a mobile module driver. The distance detection driver is used to drive the distance detection module to perform distance measurement. The mobile module driver is used to drive the mobile module to move to change the display area of the display screen.

It should be understood that the above is an example of the structural diagram of the electronic device using FIG. 3 as an example, and the software architecture of the electronic device is described by way of example through FIG. 4 , and the embodiments of the present application are not limited thereto.

The following describes the screen movement method of the embodiment of the present application in conjunction with Figures 5 and 6.

Referring to FIG. 5 , FIG. 5 shows a schematic flow chart of a method 500 for moving a screen 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 can be understood that the method 500 can be applied to the scenarios shown in FIG. 1 and FIG. 2 . As shown in FIG. 5 , the method 500 includes:

S501: Detect a first instruction, where the first instruction is used to instruct a display screen to move.

The first instruction may instruct the retractable display screen of the electronic device to move forward, or instruct the retractable display screen of the electronic device to move backward, wherein the forward direction may be understood as the direction in which the display screen is stretched, and the backward direction may be understood as the direction in which the display screen is contracted.

Optionally, as an embodiment, the first instruction is used to instruct the display screen to move, specifically including: the first instruction is used to instruct the display screen to move in the direction of the display screen stretching, wherein the size of the display screen after stretching is larger than the size of the display screen before stretching. For example, when the display area of the display screen changes from the area shown in (1) or (2) in FIG. 1 to the display area shown in (3) in FIG. 1, it is the process of display screen stretching. In this embodiment, the first instruction can also be called a stretching instruction.

Optionally, as an embodiment, the first instruction is used to instruct the display screen to move, specifically including: the first instruction is used to instruct the display screen to move in the direction of the display screen shrinking, wherein the size of the display screen after shrinking is smaller than the size 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, it is the process of shrinking the display screen. In this embodiment, the first instruction can also be called a shrinking instruction.

The first instruction may be triggered in various forms, including but not limited to hardware triggering and/or software triggering, etc., which is not specifically limited in the embodiments of the present application.

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

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

Optionally, the first instruction may be an instruction for controlling the movement of the mobile module. For example, assuming that the mobile module is driven by a motor, the first instruction may be a pulse width modulation (PWM) signal for controlling the rotation of the motor.

S502: Acquire a distance parameter through a distance detection module, where the distance parameter is used to characterize the distance that the display screen moves.

In one implementation, the distance detection module is a laser focus module. For example, the laser focus module may be disposed at a position as shown in (2) in FIG2. Other implementations of the distance detection module may refer to the above description and will not be described here.

It is understood that the laser focus module is only an exemplary description, and the present application is not limited thereto. The laser focus module can also be replaced by a sensor or module with the same function. For example, the laser focus module can be used to detect the distance the display screen moves, so the laser focus module can be replaced by a sensor for detecting the distance the display screen moves.

Specifically, the distance detection module can measure the distance that the display screen moves, and the distance that the display screen moves includes the distance that the display screen stretches, or the distance that the display screen shrinks.

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 movement; if the display screen is shrunk, the distance refers to the distance between the initial position of the display screen and the position of the display screen after the shrunk movement.

It can be understood that the distance parameter can directly represent the distance that the display screen moves, or can indirectly represent the distance that the display screen moves, and the embodiments of the present application do not specifically limit this. For example, the distance parameter can be a specific distance value, that is, it directly reflects the distance that the display screen moves. For another example, the distance parameter can record the position of the display screen after it moves. When the distance parameter is transmitted to the processor, the processor can calculate the distance that the display screen moves based on the distance parameter.

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

Optionally, the distance detection module may be connected to a processor of the electronic device via a connector (for example, as shown in the connection principle (3) in FIG. 2 ) to transmit data.

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

The embodiments of the present application do not specifically limit the detection timing of the distance detection module. For example, the distance detection module can detect the distance moved by the display screen in real time. For another example, the distance detection module can detect the distance moved by the display screen after the display screen moves. For another example, the distance detection module can detect the distance moved by the display screen in real time after detecting the first instruction.

S503: Determine whether the distance parameter satisfies a first preset condition.

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

Optionally, the first preset condition may be determined by a distance threshold. Based on the specific content indicated by the first instruction, there may be different situations in which the distance parameter satisfies the first preset condition.

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

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 of the first preset condition is only an example description, and the embodiments of the present application are not limited thereto.

S504, in response to the first instruction, when the distance parameter meets the first preset condition, control the display screen to move; when the distance parameter does not meet the first preset condition, control the display screen to stop moving.

In an embodiment of the present application, a distance parameter is obtained through a distance detection module to obtain the distance that the display screen moves, and then a decision is made as to whether the display screen moves by judging whether the distance that the display screen moves meets a first preset condition. If the distance parameter meets the first preset condition, the display screen is controlled to move; if the distance parameter does not meet the first preset condition, the display screen is controlled to stop moving. The screen movement method of an embodiment of the present application can effectively control the screen movement state of a roll-screen electronic device.

For a roll-up electronic device, the display screen can move forward or backward based on a movement instruction. In the process of the display screen moving, the embodiment of the present application can obtain the distance parameter in real time to control the reasonable movement of the display screen. The detailed embodiment is described below.

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

That is to say, if the distance parameter is judged to be less than the first distance threshold, it means that the current display screen has not yet reached the fully extended state, and the display screen can continue to stretch and move, then the display screen can be controlled to move in the stretching direction, or in the positive direction.

It can be understood that in this embodiment, the first instruction can also be called a forward movement instruction, or a stretching instruction, etc. The embodiment of the present application does not specifically limit the naming of the first instruction.

Optionally, the first distance threshold can be determined based on the fully unfolded state of the display screen. When the display screen is fully unfolded, the distance between the initial position of the display screen when it is not unfolded and the position of the display screen when it is fully unfolded can be used as the value of the first distance threshold. In addition, in a specific implementation, the gap between the distance detection module and the shell frame of the electronic device can also be considered, and the distance between the position of the distance detection module when the display screen is in the initial state when it is not unfolded and the position of the shell frame of the electronic device when the display screen is fully unfolded can be used as the first distance threshold. For example, the first distance threshold can be the distance B shown in (2) in Figure 2.

It should be understood that the above-mentioned method for determining the first distance threshold is only an exemplary description and is not specifically limited in the embodiments of the present application.

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

That is to say, if it is determined that the distance parameter is greater than the second distance threshold, it means that the current display screen has not yet reached the state where the display screen is not unfolded, and the display screen can continue to shrink and move, so the display screen can be controlled to move in the shrinking direction, or in the opposite direction.

It can be understood that in this embodiment, the first instruction can also be called a reverse movement instruction, or a contraction instruction, etc. The embodiment of the present application does not specifically limit the naming of the first instruction.

Optionally, the second distance threshold can be determined based on the unfolded state of the display screen. For example, when the display screen is not unfolded, the gap between the distance detection module and the shell frame of the electronic device can be considered, and the distance between the position of the distance detection module when the display screen is in the initial state when the display screen is not unfolded and the position of the shell frame of the electronic device when the display screen is not unfolded is used as the second distance threshold. In other words, the gap between the distance detection module and the shell frame of the electronic device is used as the second distance threshold. For example, the second distance threshold can be the distance A shown in (2) in Figure 2.

It should be understood that the above-mentioned method for determining the second distance threshold is only an exemplary description and is not specifically limited in the embodiments of the present application.

During the movement of the display screen, it is also possible to detect in real time whether a stop instruction is received, so as to respond to the user's stop operation on the display screen at any time.

Optionally, during the process of the display screen moving, the method further includes:

detecting a second instruction, wherein the second instruction is used to instruct the display screen to stop moving;

In response to the second instruction, the display screen is controlled to stop moving.

The second instruction can be understood as an instruction for the display screen to stop moving. It can be understood that the second instruction is applicable whether the display screen is stretched or contracted.

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

The second instruction may be triggered in various forms, including but not limited to hardware triggering and/or software triggering, etc., which is not specifically limited in the embodiments of the present application.

In one implementation, the second instruction may be triggered by a user by pressing a button. For example, a button may be set on the electronic device, and when the user presses the button, the second instruction is triggered.

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

Therefore, during the movement of the display screen, it can also respond to the user's stop command to stop moving the display screen, thereby improving the user's control experience over the display screen.

In an embodiment of the present application, when the display screen stops moving, the size of the display screen can be obtained based on the distance the display screen has moved, and then the content displayed on the display screen is adapted accordingly through software to obtain a display effect full of technological sense and enhance the display effect of the scroll screen.

For ease of understanding, the following is described in conjunction with the logic flow in Figure 6. As shown in Figure 6, it includes:

Step 1, determine whether a forward movement instruction is detected.

For example, the forward movement instruction may correspond to the first instruction mentioned above. The first instruction is specifically used to instruct the display screen to move in the direction in which the display screen is stretched.

If a forward movement command is detected, step 2 is executed; if no forward movement command is detected, step 9 is executed.

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

Step 2: Determine whether the distance parameter is less than a first distance threshold.

If the distance parameter is less than the first distance threshold, step 3 is executed; if the distance parameter is not less than the first distance threshold, step 9 is executed. The description of the first distance threshold can be referred to in the previous text, and for the sake of brevity, it is not repeated here. In this way, when it is judged that the first distance threshold is reached, the display screen will automatically stop moving, or automatically execute the stop command, so as to avoid invalid movement of the display screen, which helps to save terminal power consumption.

Step 3: The display screen moves in a positive direction. The positive movement is the movement in the direction of stretching the display screen mentioned above.

Step 4: Determine whether a stop command (corresponding to the second command in the previous text) is detected. The stop command is used to instruct the display screen to stop moving.

If a stop command is detected, execute step 9; if no stop command is detected, execute step 2.

Step 5, determine whether a reverse movement instruction is detected.

For example, the reverse movement instruction may correspond to the first instruction mentioned above. The first instruction is specifically used to instruct the display screen to move in the direction of shrinking the display screen.

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

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

Step 6: Determine whether the distance parameter is greater than a second distance threshold.

If the distance parameter is greater than the second distance threshold, step 7 is executed; if the distance parameter is not greater than the second distance threshold, step 9 is executed. In this way, when it is determined that the second distance threshold is reached, the display screen will automatically stop moving, or automatically execute the stop command, to avoid invalid movement of the display screen, which helps to save terminal power consumption.

Step 7: The display screen moves in the reverse direction. The reverse movement is the movement in the direction of shrinking the display screen mentioned above.

Step 8, determine whether a stop command (corresponding to the second command in the previous text) is detected. The stop command is used to instruct the display screen to stop moving. If the stop command is detected, execute step 9; if the stop command is not detected, execute step 6.

Step 9, the display stops moving.

It should be understood that the specific process shown in FIG. 6 is only for the convenience of understanding of those skilled in the art, and the embodiments of the present application are not limited thereto.

From the above, it can be seen that the screen movement method provided in the present application obtains the distance parameter through the distance detection module, and determines whether the distance parameter meets the first preset condition to determine whether the display screen moves, which can effectively control the screen movement state of the rolling screen electronic device.

The above text, in conjunction with Figures 1 to 6, details a method for moving a screen provided by an embodiment of the present application.
