Curved Display Edge Touch Selection via Input Control Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User interface selectable controls displayed within the curved edges of a curved display screen on mobile devices are difficult to select due to the curved transition from the flat to the curved surface, leading to challenges in registering user touch inputs.
Innovation Solution
An input control module is implemented to detect touch inputs proximate selectable elements within the curved display edge, determining if the input is within an element selection distance threshold as an intended selection, allowing for activation of corresponding device application actions even if the user does not directly contact all or some of the element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If selectable controls are displayed within the curved edges of the display screen, then the display screen can show more user interface content and enhance aesthetics, but the curved edges make it difficult for users to accurately select the controls due to the curved transition from flat to curved surface
Solution Approach 1:
The patent introduces an intermediary mechanism (the curved transition region with adjusted touch sensitivity or expanded selection zone) that mediates between the user's touch input and the selectable control. This intermediary allows users to select controls displayed on curved edges by accounting for the curved surface geometry, thereby resolving the contradiction between expanded display area and ease of selection.
2Shape
If the display screen uses a curved edge design, then the device aesthetics are enhanced, but touch input registration for selectable controls becomes unreliable due to the curved surface geometry
Solution Approach 1:
The patent applies parameter changes by modifying the touch sensitivity or selection threshold parameters in the curved transition region. By adjusting these parameters to account for the curved surface geometry, the system maintains reliable touch input registration while preserving the curved display edge design, thus resolving the contradiction between aesthetic shape and input reliability.
3Adaptability or versatility
If selectable controls are placed on the curved transition region, then more controls can be displayed within the curved edges, but the controls become harder to select accurately due to the curved surface
Solution Approach 1:
The patent segments the display screen into different regions (flat display area and curved edge regions) with different selection criteria. By segmenting the touch input processing based on the spatial location of controls, the system can maintain measurement precision for controls on curved edges while preserving the flexibility to place controls in various locations, thus resolving the contradiction between adaptability and precision.

AI summary
In aspects of selectable element selection within a curved display edge, a wireless device has a display screen with curved display edges to display a user interface that includes one or more selectable elements to initiate respective device application actions. The wireless device implements an input control module, which can detect that a selectable element of the user interface is displayed at least partially within a curved display edge of the display screen. The input control module can receive a touch input proximate the selectable element of the user interface, and determine that the touch input is received within an element selection distance threshold as an intended touch input to select the selectable element. The input control module can then initiate to activate a respective device application action based on the intended touch input being proximate the selectable element within the element selection distance threshold.
