Mobile Terminal Display Integration via Wired Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Android OS does not support the integration of multiple displays, limiting mobile terminals to only two displays with the same resolution, and integrating multiple screens results in a clipped display due to physical distance between them.
Innovation Solution
An electronic device comprising a mobile terminal and a case with a controller that enables wired communication to integrate two displays with different hardware specifications, overcoming the clipping issue by dividing images and adjusting display sizes for an extended display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If two displays are integrated to extend display area, then display area is increased, but clipping occurs due to physical distance between displays
Solution Approach 1:
A virtual overlapping area is introduced as an intermediary between the two physical displays. This virtual area compensates for the physical distance gap by creating a software-based transition zone that seamlessly connects the edge display area with the main display, eliminating the clipping effect caused by physical separation.
Solution Approach 2:
The system dynamically adjusts display parameters including the position and size of the overlapping area, the dividing line position, and the scaling factors for sub-images. By changing these parameters, the system optimizes the integration of multiple displays with different specifications while maintaining image quality and eliminating clipping artifacts.
2Adaptability or versatility
If multiple displays with different specifications are integrated, then display versatility is improved, but OS compatibility is limited
Solution Approach 1:
The case is designed with a universal connector that can interface with various mobile terminal models through wired communication. The system implements multi-functional capability by supporting integration of displays with different specifications (different resolutions, sizes, and hardware characteristics) through a single unified architecture, eliminating the need for model-specific implementations.
3Device complexity
If displays are integrated through wireless communication, then device complexity is reduced, but communication reliability is insufficient
Solution Approach 1:
The patent replaces wireless communication (electromagnetic field-based) with wired mechanical connection. The connector physically couples the case with the mobile terminal, providing stable electrical contact for data and power transmission. This substitution eliminates the instability and interference issues inherent in wireless communication while maintaining reasonable device complexity through modular design.
