Foldable Display Input Configuration for Partial Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices with large displays face inaccuracies in touch inputs when partially folded, as inputs to the region distal from the floor can cause device movement, leading to input errors due to the same touch input method being used across divided sub-areas.
Innovation Solution
An electronic device with a foldable display that configures different input methods based on its state, setting one region to accept touch inputs and another to accept non-touch inputs when partially folded, using sensors to determine the display's state and regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the same touch input method is used for all display regions, then the device structure remains simple, but input accuracy deteriorates when the display is partially folded
Solution Approach 1:
The patent applies local quality by configuring different input methods for different display regions based on their spatial position and orientation when partially folded. The first region (proximal to the hinge) uses touch input, while the second region (distal from the hinge) uses non-touch input, allowing each region to have optimized input behavior for its specific usage scenario.
Solution Approach 2:
The patent implements dynamics by making the input method configuration changeable based on the display's folding state. The system dynamically switches between different input configurations (touch vs. non-touch) depending on whether the display is fully unfolded or partially folded, allowing the input method to adapt to the current device state.
2Area of stationary object
If the display is divided into multiple regions, then the display area utilization increases, but the reliability of touch input decreases due to device movement
Solution Approach 1:
The patent divides the display into multiple regions with different input characteristics. The first region (proximal to the hinge) is configured for touch input, while the second region (distal from the hinge) is configured for non-touch input. This local differentiation allows each region to maintain reliable input based on its physical characteristics and usage scenario.
Solution Approach 2:
The patent segments the display into functionally distinct regions based on their spatial position and input behavior. By segmenting the display area and assigning different input methods to different segments, the system maintains reliability while maximizing display area utilization.
3Ease of operation
If the display is partially folded, then the device portability improves, but the touch input accuracy deteriorates due to gravity-induced movement
Solution Approach 1:
The patent dynamically adapts the input method based on the display's folding state. When partially folded, the system automatically configures the distal region to use non-touch input, preventing input errors caused by gravity-induced movement. This dynamic adaptation maintains input accuracy while preserving the portability benefits of partial folding.
Solution Approach 2:
The patent applies different input qualities to different regions based on their susceptibility to gravity-induced movement. The proximal region (less affected by gravity) uses touch input, while the distal region (more affected by gravity) uses non-touch input, optimizing input accuracy for each region's specific gravitational conditions.
