Dual-Screen Display Control via Shared OS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual-screen electronic devices face challenges in cursor switching and increased cost due to the need for a separate ARM-based system for each screen, which complicates data display and increases hardware requirements.
Innovation Solution
A display control method that allows different data to be displayed on each screen of a dual-screen electronic device using a shared operating system, where a processor determines and displays distinct portions of data on each screen, enabling efficient cursor switching without the need for separate processors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate ARM-based system is used for each screen in dual-screen devices, then cursor switching and system independence are improved, but hardware cost and device complexity increase
Solution Approach 1:
The patent merges the operating system resources of two separate systems into a single shared operating system that can manage multiple display screens simultaneously. This consolidation eliminates the need for separate ARM-based systems for each screen, reducing hardware complexity while maintaining the ability to display different content on each screen and improve cursor switching efficiency.
Solution Approach 2:
The shared operating system is designed to perform multiple functions: it can manage a single display screen, multiple display screens simultaneously, switch between different display modes, and handle cursor operations across screens. This multi-functional approach replaces the need for dedicated separate systems, reducing overall device complexity while improving operational flexibility.
2Reliability
If a separate ARM-based system is used for each screen in dual-screen devices, then system independence is improved, but hardware cost increases
Solution Approach 1:
The patent combines multiple independent system requirements into a single shared operating system that provides the functional independence previously achieved through separate hardware systems. By sharing common resources such as the processor, memory, and operating system kernel while maintaining independent display management capabilities, the solution reduces hardware cost while preserving system independence through software architecture rather than physical separation.
3Adaptability or versatility
If a separate ARM-based system is used for each screen, then display functionality is improved, but space occupation increases
Solution Approach 1:
The shared operating system is designed to adapt to various display configurations including single screen, multiple screens, different resolutions, and various display modes (mirror, extend, presentation). This universal display management capability replaces the need for separate dedicated systems for each screen, maintaining full display functionality while reducing the space occupied by hardware components through resource sharing and virtualization.

AI summary
Display control method, electronic device, and non-transitory computer-readable storage medium are provided. The display control method includes determining data to be displayed corresponding to an operating system of an electronic device; displaying a first portion of the data to be displayed in a first display device of the electronic device; and displaying a second portion of the data to be displayed in a second display device of the electronic device. The first portion is different from the second portion, and the first display device and the second display device perform display based on a same operating system of the electronic device.
