Foldable Display Edge Touch Shielding Using Grip Gesture Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The issue of false touch on the edge of foldable flexible display screens in mobile terminals occurs when the user inadvertently touches the screen while holding the device in a folded state, as both sides of the fold serve as display surfaces, leading to inaccurate touch inputs.
Innovation Solution
Implementing a method that utilizes intelligent gesture recognition to identify and shield false touch events on the edges by detecting user gestures, such as one-handed or two-handed holding patterns, to prevent unintended interactions.

Engineering Contradiction Analysis
1Volume of moving object
If the flexible display screen is used in a folded state to reduce occupied space, then the portability of the mobile terminal is improved, but false touch events occur on the edge of the screen
Solution Approach 1:
The patent applies local quality by treating the edge region of the display screen differently from the central region. A preset threshold distance from the edge is defined, and touch events within this edge region are handled with special logic (ignoring them as false touches), while touch events in the central region maintain normal functionality. This localized differentiation resolves the contradiction by preserving portability benefits while eliminating false touch issues in the specific edge area.
Solution Approach 2:
The patent introduces an intermediary mechanism in the form of a distance threshold calculation system. When a touch event occurs, the system calculates the distance from the touch location to the edge of the display screen and uses this intermediate value to determine whether to ignore the touch event. This intermediary calculation enables the system to distinguish between intentional touches and false touches caused by holding the device, thereby maintaining both compact form factor and reliable input.
2Device complexity
If the edge of the terminal is made part of the display screen to maintain a compact design, then the device complexity is reduced, but false touch events increase due to user grip
Solution Approach 1:
The patent applies local quality by treating the edge region of the display screen differently from the central region. A preset threshold distance from the edge is defined, and touch events within this edge region are handled with special logic (ignoring them as false touches), while touch events in the central region maintain normal functionality. This localized differentiation resolves the contradiction by preserving portability benefits while eliminating false touch issues in the specific edge area.
Solution Approach 2:
The patent converts the harmful false touch events caused by user grip into a beneficial feature by using the edge detection mechanism to intentionally ignore touches in the edge region. The system leverages the fact that users naturally grip the edges of their devices to automatically distinguish between intentional touches (in central regions) and unintentional touches (in edge regions), thereby eliminating false touches without adding complex hardware.

AI summary
A method, a terminal, and a storage medium are provided for preventing a false touch on an edge. The method is applied to a mobile terminal. A display screen of the mobile terminal is in a folded state. The display screen includes n display areas, and n is a positive integer not less than 2. The method includes: detecting a touch event for at least one edge of the mobile terminal, where the at least one edge is a non-metallic material edge of the mobile terminal; acquiring a gesture of a user currently holding the mobile terminal, when the touch event for the at least one edge is detected; and shielding the touch event for the at least one edge, when the gesture of the user holding the mobile terminal matches a target gesture.
