Multi-Device Page Control for Unified Split-Screen Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to provide a seamless split-screen experience across multiple devices, particularly when a user possesses multiple devices and desires a unified split-screen functionality similar to that of a foldable screen.
Innovation Solution
A page control method and apparatus that enables split-screen display across multiple electronic devices by using a device pointer array to manage page operations, allowing for page addition, deletion, and switching through a master control device, which coordinates display pages across N first electronic devices connected in a wired or wireless manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing split-screen technologies are applied to multiple devices, then users can achieve split-screen display on a single device, but the system cannot provide unified split-screen experience across multiple devices
Solution Approach 1:
The patent segments the control function by introducing a master control device that manages page operations for multiple slave devices. The device pointer array is segmented into N elements, each corresponding to a specific device, allowing independent page management while maintaining unified control architecture.
Solution Approach 2:
The master control device serves multiple functions: it receives page operation instructions from any device, manages the device pointer array for N devices, coordinates page display across all devices, and handles synchronization. This universal controller enables unified split-screen experience without requiring each device to implement full functionality independently.
2Ease of operation
If a device pointer array is used to manage pages across N devices, then unified page control is achieved, but the control system becomes more complex
Solution Approach 1:
The device pointer array acts as an intermediary data structure between the master control device and N slave devices. Each element in the array stores the current page identifier for a specific device, enabling the master device to efficiently coordinate page operations without direct complex communication with each slave device individually.
Solution Approach 2:
The master control device automatically manages page synchronization based on user operations on any device. When a user interacts with a page on one device, the system automatically updates the device pointer array and synchronizes the corresponding pages across all devices without requiring manual intervention or complex user commands.
3Adaptability or versatility
If multiple devices are connected for split-screen display, then unified display experience is enabled, but coordination and synchronization become more difficult
Solution Approach 1:
The system establishes connection relationships between devices and initializes the device pointer array before actual page display operations begin. The master control device pre-configures the mapping between devices and their corresponding pages, enabling smooth synchronization during operation without real-time complex coordination.
Solution Approach 2:
The master control device continuously monitors page operation instructions from any device and uses feedback to update the device pointer array. When a page operation is detected on one device, the system feeds back the updated page state to all other devices through the pointer array, ensuring consistent synchronization across the entire multi-device system.

AI summary
This application discloses a page control method and apparatus, and an electronic device. The method includes: obtaining a page touch operation instruction; controlling, in response to the page touch operation instruction, display of a target page triggered by the page touch operation instruction on a target electronic device among N first electronic devices based on an indication state of a device pointer array, where the device pointer array includes device pointers of the N first electronic devices, each device pointer is used to indicate a display page of a corresponding first electronic device, and N is a positive integer greater than 1.
