Edge Touch Blocking Area for Curved Display Malfunctions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for processing touch events in electronic devices with curved or flexible displays often result in unintended touch inputs, leading to malfunctions, as they rely on simplistic conditions like touch area or time, which can misinterpret user intentions, especially when the user grips the device.
Innovation Solution
The electronic device employs a touch event filtering method that distinguishes between intended and unintended touch inputs by analyzing the shape and area of the touch region, using a touch blocking region to disregard unintended inputs, thereby preventing malfunctions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a touch blocking region is set at the edge of the display to prevent unintended touch inputs, then reliability is improved, but the display area is reduced
Solution Approach 1:
The patent applies different touch processing characteristics to different regions of the display. The edge region has touch blocking enabled to prevent unintended inputs during gripping, while the non-edge region maintains normal touch responsiveness. This local differentiation resolves the contradiction by applying the touch blocking region only where necessary (at edges) rather than globally, thus improving reliability without significantly reducing the overall display area.
2Device complexity
If simple conditions like touch area or touch time are used to process touch events, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The patent changes the parameter used for touch event processing from simple conditions (touch area, touch time) to position-based conditions (whether the touch is in the edge region or non-edge region). This parameter change maintains relatively low device complexity while improving measurement precision, as the position-based approach more accurately distinguishes between intended and unintended touches without requiring complex analysis of touch duration or area.
3Reliability
If the entire edge region is blocked from touch input, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent applies touch blocking only to the edge region while leaving the non-edge region fully responsive to touch inputs. This local quality approach ensures that reliability is improved by blocking unintended touches at the edges, while ease of operation is maintained because the majority of the display area (non-edge region) remains fully operational for intended touches.

AI summary
Various embodiments of the present invention provide a method and apparatus for preventing a user's unintentional touch input in an electronic device. According to various embodiments of the present invention, an electronic device may comprise: a display for displaying a user interface; a memory; and a processor functionally connected to the display and the memory, wherein the processor is configured to set a touch blocking area in the edge area of the display, determine an exception area in the touch blocking area on the basis of the user interface, remove the determined exception area from the touch blocking area, so as to set a final touch blocking area, and process a touch event on the edge area on the basis of the final touch blocking area. Various embodiments are possible.
