Flexible Display Screen Module for Modular Terminal Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminals have small screens that are inconvenient for browsing and editing documents, and old mobile phones with good screens are often discarded due to low battery capacity or configuration, leading to pollution issues and a need for a solution to repurpose their screens.
Innovation Solution
A modular terminal device composed of multiple mobile terminals with flexible display screens that can be expanded and folded, featuring a control unit and sensing unit to adjust transparency and touch sensitivity based on angle changes, allowing for easy assembly into a larger screen and convenient carrying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the screen size of a mobile terminal is increased to improve browsing and document editing convenience, then the usability for office work is improved, but the portability and carrying convenience deteriorate
Solution Approach 1:
The display screen is divided into multiple flexible display modules that can be separated and connected. Each module contains a flexible display unit with touch sensing layers, allowing the screen to be segmented into portable units while maintaining the ability to expand to a large display area when connected, thus resolving the contradiction between large screen usability and small size portability
Solution Approach 2:
The display screen transitions from a static fixed-size design to a dynamic configurable size. The flexible display modules can be connected in different configurations (series/parallel connections) to change the overall display area and functionality. Users can dynamically adjust the screen size and configuration based on usage scenarios, making the terminal adaptable between large-screen office work mode and small-size portable mode
2Adaptability or versatility
If old mobile phones with good screens are discarded to replace them with new devices, then the new device performance is improved, but electronic pollution increases and resource waste occurs
Solution Approach 1:
The invention enables recovery and reuse of flexible display modules from old mobile phones. Instead of discarding old devices, the flexible display units can be extracted and integrated into new terminal devices. This allows the display components of old phones to be recovered and put to new use, reducing electronic waste and the need for new display manufacturing
Solution Approach 2:
The flexible display modules are designed with universal compatibility to work in different terminal devices. The modules can be integrated into various types of terminals (smartphones, tablets, wearables) and configured for different functions. This universality allows old display units to serve multiple purposes across different device types, maximizing resource utilization
3Adaptability or versatility
If a flexible display screen is used to enable screen expansion and folding, then the adaptability between large-screen and portable modes is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The display system is segmented into standardized flexible display modules with standardized connection interfaces. Each module contains integrated touch sensing layers, display units, and connection structures. This segmentation allows modules to be connected using standardized interfaces, reducing the complexity of custom integration while enabling flexible configurations
Solution Approach 2:
The flexible display modules are designed with self-contained functionality, including integrated touch sensing layers, display units, and connection structures. The modules can be independently manufactured and tested before being connected to form the complete display system, reducing the complexity of manufacturing and quality control
