Mobile Terminal Split-Screen Control for External Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a mobile terminal that can conveniently and efficiently control the screen states of multiple external devices when their content is output on a display device, as existing methods require manual control through remote controllers or keys, lacking a user-friendly interface for managing split-screen configurations and device settings.
Innovation Solution
A mobile terminal with a display unit featuring a first and second display region, a wireless communication unit, and a controller that transmits control signals to manage the split-screen state, sound source, and aspect ratio of external devices connected to a display device, allowing users to easily change output positions, sound sources, and aspect ratios through a screen control application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual control through remote controllers or keys is used, then device functionality is maintained, but user convenience and ease of operation deteriorates
Solution Approach 1:
The patent introduces a mobile terminal as an intermediary device between the user and the display device. The mobile terminal transmits control signals to manage screen states, split-screen configurations, and device settings, eliminating the need for manual remote controller or key operations while maintaining full control functionality.
2Productivity
If multiple external devices are connected and controlled individually, then device versatility is maintained, but control efficiency and productivity deteriorates
Solution Approach 1:
The mobile terminal serves as a universal control device that can manage multiple external devices simultaneously. It provides a unified interface for controlling screen states, split-screen options, sound sources, and aspect ratios across different devices, significantly improving control efficiency over individual device management.
3Ease of operation
If screen control is implemented without mobile terminal integration, then system simplicity is maintained, but user convenience and ease of operation deteriorates
Solution Approach 1:
The system enables self-service operation where the mobile terminal autonomously transmits control signals to manage display device functions. Users simply interact with their mobile terminal interface, and the system automatically handles screen state changes, split-screen configurations, and device control without requiring additional power-intensive components in the display device itself.
