Solution Overview
Problem
Existing electronic devices with touch sensors struggle to accurately differentiate between different types of touch inputs, particularly when the device is folded or bent, leading to inconsistent touch sensitivity and recognition.
Innovation Solution
The electronic device employs a touch sensor with distinct sensitivity settings in different regions, adjusting recognition based on contact values relative to reference thresholds, allowing for differentiated touch input identification in various device configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single touch sensitivity setting is used across the entire display, then the device structure is simple, but touch input recognition accuracy deteriorates when the device is folded or bent
Solution Approach 1:
The touch sensor is divided into multiple regions (first region and second region) with different sensitivity settings. The first region uses a first touch sensitivity while the second region uses a second touch sensitivity, allowing each region to be optimized for its specific functional requirements in folded or bent configurations.
Solution Approach 2:
Different portions of the touch sensor are assigned different touch sensitivity characteristics. The first portion of the touch sensor has a first touch sensitivity and the second portion has a second touch sensitivity, enabling localized optimization for accurate touch recognition in specific areas of the display.
2Adaptability or versatility
If the display is made flexible or folded to enable compact designs, then device portability is improved, but touch sensitivity consistency deteriorates
Solution Approach 1:
The touch sensor system dynamically adjusts sensitivity settings based on the display's operational state. When the display is in a folded or bent configuration, the system activates different sensitivity levels in different regions to maintain reliable touch recognition despite the changed physical state.
Solution Approach 2:
The touch sensitivity parameter is changed across different regions of the display. By setting the first region with a first touch sensitivity and the second region with a second touch sensitivity, the system compensates for the effects of folding or bending to maintain consistent and reliable touch input recognition.
3Measurement precision
If different touch sensitivity settings are implemented in different regions, then touch input recognition accuracy is improved, but the control system complexity increases
Solution Approach 1:
The touch sensor is segmented into multiple regions with distinct sensitivity characteristics. This segmentation allows the system to process touch inputs differently in different areas, improving accuracy for differentiated touch recognition while managing complexity through modular region-based control.
Solution Approach 2:
The touch sensitivity settings for different regions are pre-configured before use. The first region is set with a first touch sensitivity and the second region with a second touch sensitivity in advance, allowing the system to immediately provide accurate touch recognition without requiring complex real-time adjustments.
