Foldable Display Touch Panel State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable display apparatuses face issues with accidental touch operations during opening and closing, leading to erroneous interactions due to the flexibility of both the display and touch panels, which existing techniques fail to prevent effectively.
Innovation Solution
Incorporating an open-close detection device and a control device with a processor that invalidates touch operations during open-close movement states and validates them in neutral, open, or closed states, ensuring accurate user input by determining the state of the display and touch panel through angle thresholds and movement detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display device and touch panel are made foldably flexible to enable the apparatus to be openable and foldable, then the adaptability and portability of the apparatus is improved, but erroneous touch operations occur during opening and closing movements
Solution Approach 1:
The control device preliminarily determines the state of the openable body (open state, close state, or open-close movement state) before processing touch operations. By detecting the state in advance using detection devices, the system prevents erroneous operations during movement states while maintaining normal touch functionality during stable open or closed states, thus resolving the contradiction between foldable capability and touch operation accuracy
2Ease of operation
If touch operations are continuously validated to ensure responsive user interaction, then the ease of operation is improved, but erroneous operations during open-close movement cannot be prevented
Solution Approach 1:
The validation status of touch operations is dynamically adjusted based on the detected state of the openable body. The control device changes the validation state from always valid to conditionally valid (invalid during open-close movement state, valid during open or close states), making the system adaptive to different operational contexts and preventing erroneous operations while maintaining responsiveness when appropriate

AI summary
A display apparatus includes a controller that invalidates, while an open-close movement state is being detected by an open-close detection device, a touch operation made on a touch panel, and that validates the touch operation made on the touch panel, when either of an open state and a close state is being detected by the open-close detection device and when in a neutral state, the neutral state being where none of the open-close movement state, the open state, and the close state is being detected by the open-close detection device.
