Hybrid Touch Screen for Hovering Input Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch screens in electronic devices can only receive input through direct contact, limiting the interface to direct touch effects and lacking the ability to provide other input methods beyond finger or pen touch.
Innovation Solution
An electronic device and method that senses the position and height of an input means above the screen, allowing for hovering input effects such as brush writing, chisel, spray, droplet falling, ink spreading, and stamp effects, using a hybrid touch screen with capacitive and ElectroMagnetic Resonance (EMR) panels to distinguish between touch and hover inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional capacitive touch screen is used, then direct touch input can be detected, but hovering input effects cannot be provided
Solution Approach 1:
The patent combines a capacitive touch panel and an EMR touch panel into a hybrid touch screen structure. The capacitive panel detects finger touches while the EMR panel detects hovering pens, allowing both direct touch and hovering input methods to coexist in a single device without requiring separate sensing systems.
Solution Approach 2:
The hybrid touch screen serves multiple functions: it detects both direct finger touches and hovering pen inputs, and it provides different input effects based on the detected input type. This multi-functionality resolves the contradiction by enabling versatile input methods while using a unified touch screen structure.
2Adaptability or versatility
If only direct touch is supported, then the interface is simple, but hovering input effects such as brush writing, chisel, spray, and ink spreading cannot be displayed
Solution Approach 1:
The patent implements dynamic input effects that change based on the hovering height and movement of the pen. Effects such as brush writing, chisel, spray, and ink spreading are dynamically displayed according to the detected height information, allowing the interface to adaptively provide diverse effects without requiring separate static interfaces for each effect type.
Solution Approach 2:
The patent uses height parameter detection to control the display of different input effects. By monitoring changes in the hovering height parameter, the system dynamically switches between various input effects (brush writing, chisel, spray, etc.), enabling versatile input effects while maintaining a unified interface structure.
3Measurement precision
If a hybrid touch screen with EMR and capacitive panels is used, then hovering and touch inputs can be distinguished, but the device structure becomes more complex
Solution Approach 1:
The patent divides the touch sensing function into two separate panels: a capacitive touch panel for detecting finger touches and an EMR touch panel for detecting hovering pens. This segmentation allows each panel to be optimized for its specific detection task, improving measurement precision while keeping the overall structure modular and manageable.
Solution Approach 2:
The patent introduces an EMR touch panel as an intermediary layer between the capacitive panel and the user's hovering pen. The EMR panel specifically detects hovering inputs without interfering with finger touch detection by the capacitive panel, enabling precise distinction between different input types through the intermediary's specialized sensing capability.
