Display Device with Separate Touch Screen for Flexible Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Single-screen displays struggle to meet the diverse application requirements of modern scenarios, particularly in needing high-definition, easy-to-view displays that can switch modes and provide synchronous information without delay, while also integrating touch and display functions effectively.
Innovation Solution
A display device comprising a display screen and a touch screen with a communication connection, controlled by a controller that adjusts display content based on input instructions from the touch screen, allowing for flexible and simultaneous display and touch-control functions on either a single or multiple curved surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-screen display is used, then the device structure is simple, but it cannot satisfy diverse application requirements and cannot integrate touch and display functions effectively
Solution Approach 1:
The display screen is designed to perform multiple functions by integrating both display and touch control capabilities. The controller can execute instructions from either the display screen or the touch screen, allowing the same hardware component to serve dual purposes depending on the operational mode, thereby satisfying diverse application requirements without proportionally increasing device complexity
Solution Approach 2:
The system dynamically switches between different operational modes where the display screen can function as either a display-only component or a touch-control component. The controller adapts its behavior based on input source, enabling the device to flexibly respond to different application scenarios and user interaction needs
2Ease of operation
If touch and display functions are integrated in a single screen, then the device complexity is reduced, but the separation operation capability is lost
Solution Approach 1:
The system is segmented into functionally independent display and touch control modules that can operate separately. The controller is configured to accept instructions from either the display screen or the touch screen independently, enabling separation operation where one function can be used without the other while maintaining the capability for integrated operation when needed
3Adaptability or versatility
If multiple curved surfaces are used for display, then the adaptability to diverse scenarios is improved, but the device complexity increases
Solution Approach 1:
The patent employs flexible display screens and touch screens that can be configured on curved surfaces. These flexible components allow the device to adapt to various curved surface geometries and installation scenarios without requiring rigid, scenario-specific hardware designs, thereby achieving multi-scenario adaptability while controlling structural complexity through material flexibility
