Mobile Terminal Dual-Side Display Input Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to effectively control input sensing on both sides of a mobile terminal with a foldable display to prevent false operations when the display is used on both the front and rear sides, particularly due to unintentional touch inputs during handling.
Innovation Solution
A mobile terminal design with a camera on one side and a controller that displays images acquired on both the front and rear display areas, allowing the controller to adjust the display based on the terminal's pose and usage pattern to prevent false inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display is provided on both the front side and the rear side of the mobile terminal, then the usability and functionality of the device are improved, but false operations may occur due to unintentional touch inputs during handling
Solution Approach 1:
The patent applies dynamics by making the touch sensitivity of the display dynamic rather than static. The controller adjusts the touch sensitivity threshold based on the detected pose of the mobile terminal. When the terminal is in a pose where unintentional touches are likely (e.g., held in one hand), the touch sensitivity is reduced to prevent false inputs. When the terminal is in a pose where intentional touches are more certain (e.g., held with both hands), the touch sensitivity is increased to improve responsiveness. This dynamic adjustment resolves the contradiction between maintaining high usability and preventing false operations.
2Area of stationary object
If the display is folded or rolled to increase screen area, then the display size is improved, but the device complexity increases
Solution Approach 1:
The patent employs flexible shells and thin films by utilizing a flexible display that can be folded or rolled. The display is constructed with flexible materials that allow it to be deformed into different configurations (folded or rolled states) to increase the effective screen area when needed. This flexible structure enables the display to transition between compact and expanded states without requiring complex mechanical mechanisms, thereby increasing display area while managing device complexity through material flexibility rather than mechanical complexity.
