Description

Technical Field

[0001] The present application relates to the field of computer application technology, and for example, to a method and system for adaptively flipping screen display of a secondary screen, and an electronic device. Background Art

[0002] With the popularity of multi-screen devices and rotatable screens, the secondary screen has become an important component in many high-end devices and professional applications. However, the problem of inconsistent display direction of the secondary screen has seriously restricted the application effect and user experience of these devices.

[0003] In traditional devices, when the secondary screen rotates, the system cannot automatically detect its rotation status, which often causes the displayed content to not match the user's viewing angle, requiring the user to manually adjust it. This not only increases the complexity of user operations, but also seriously affects the user experience, especially in scenarios where the secondary screen needs to be rotated frequently.

[0004] Specifically, when the user rotates the secondary screen to adapt to different viewing needs or application scenarios, the screen content does not automatically adjust, resulting in the wrong display direction. The user must manually trigger the screen flip function to correct this problem. This happens mainly because the system lacks an effective mechanism to detect and respond to the rotation of the secondary screen in real time.

[0005] In addition, existing secondary screen rotation technologies generally lack adaptability to different operating systems. This means that when users switch between different operating systems (such as Windows, macOS, Linux, Android, etc.) or use cross-platform devices, the secondary screen rotation function may not work properly or require users to perform complex settings and adjustments.

[0006] Specifically, due to differences in the support and implementation of screen rotation in different operating systems, existing secondary screen rotation technologies can often only be optimized for a specific system or platform, and cannot achieve seamless compatibility across platforms. For example, some secondary screen rotation solutions that perform well on Windows systems may experience inaccurate recognition, slow response, or even complete failure when switching to macOS or Linux systems. This not only increases the user's usage cost and learning burden when switching between different systems, but also limits the application scope and market potential of secondary screen devices.

[0007] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

The attached drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0038] The terms "first", "second", etc. in the embodiments of the present disclosure are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so as to describe the embodiments of the present disclosure described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0039] Unless otherwise stated, the term "plurality" means two or more.

[0040] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.

[0041] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0042] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0043] Combination Figure 1 The screen display adaptive flipping system for the secondary screen includes a sensor, a single-chip microcomputer and a system application.

[0044] The sensor is used to monitor the screen rotation angle in real time;

[0045] The microcontroller and the sensor are connected via an I2C interface to receive, process, and calibrate the rotation angle data, and determine whether the screen needs to be flipped;

[0046] The system application communicates with the microcontroller to receive the protocol key value sent by the microcontroller and perform the screen flipping action.

[0047] It is understandable that the hardware design of the present disclosure selects suitable single-chip microcomputer chips and sensor chips (sensors) as core components. The single-chip microcomputer is responsible for data processing and communication control, and the sensor chip is used to detect the rotation angle of the screen. The sensor chip is connected to the single-chip microcomputer through the I2C interface to realize real-time data transmission. At the same time, the necessary data acquisition channels and transmission channels are designed to ensure the accuracy and stability of the data.

[0048] In terms of software algorithms: Write a microcontroller program to realize data reception, processing, calibration and flip judgment. The program first receives the rotation angle data transmitted by the sensor chip, and then performs data analysis and calibration to eliminate errors. Finally, it determines whether the screen needs to be flipped based on the calibrated data and generates the corresponding protocol key value.

[0049] In terms of system integration: hardware and software are combined to form a complete automatic screen flip control system. After the system is started, the microcontroller continuously monitors the data of the sensor chip. Once it detects that the screen rotation angle reaches the preset threshold, it automatically triggers the flip action. At the same time, the system supports multiple operating system platforms and realizes screen flipping by calling the corresponding system API or executing specific commands.

[0050] like Figure 1 As shown, the method when using the above system includes:

[0051] 1) Initialize the MCU and Sensor chip to establish a communication connection.

[0052] 2) The microcontroller continuously receives the rotation angle data transmitted by the Sensor chip.

[0053] 3) The microcontroller processes, calibrates and flips the received data.

[0054] 4) Generate a protocol key value based on the judgment result and send it to the system application through the I2C interface.

[0055] 5) The system application receives the protocol key value and calls the corresponding instruction according to the operating system category to perform the screen display flipping action.

[0056] It can be understood that the present invention monitors the screen rotation angle in real time through the sensor set on the secondary screen, and transmits the rotation angle data detected by the sensor to the single-chip microcomputer through the communication interface; after receiving the data, the single-chip microcomputer processes and calibrates it, and determines whether the screen needs to be flipped; if the judgment result is that flipping is required, the single-chip microcomputer generates a protocol key value and sends it to the system application through the communication interface; after receiving the protocol key value, the system application calls the corresponding instruction according to the operating system category to execute the screen flipping action.

[0057] The system application determines whether the data sent by the single chip microcomputer is received by interruption or polling. The single chip microcomputer includes steps of filtering, denoising and calibrating the data during data processing to improve the accuracy of flip judgment.

[0058] In addition, the system application takes different necessary processing according to the received protocol key value and different systems. Specifically, the screen flipping can be realized by calling the API provided by the operating system or executing a specific command. For example, in Windows series systems, the screen flipping is realized by calling the system's built-in screen rotation shortcut key; in systems such as Kylin, the screen flipping is realized by calling Xrander's instructions.

[0059] An embodiment of the present disclosure provides an electronic device, including the aforementioned screen display adaptive flipping system for a secondary screen, and a screen connected thereto, wherein the screen can be automatically flipped according to the protocol key value of the system application.

[0060] The present invention includes three parts: hardware design, software algorithm and system integration. The hardware part is responsible for data collection and transmission; the software algorithm part is responsible for data processing and flip judgment; the system integration part is responsible for combining software and hardware to realize full-automatic screen flip control.

[0061] The present invention automatically detects the screen rotation state and triggers the flipping operation through the coordinated work of the sensor, the single-chip microcomputer and the screen flipping program, thereby improving the user experience and reducing the user operation burden.
