Bezel-Less Foldable Display Mount via Adhesive Cover Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices with bezels face challenges such as interference with user interaction, reduction in active display area, and aesthetic detraction due to the bezel's presence.
Innovation Solution
A bezel-less display mount for foldable electronic devices is implemented, featuring a housing with a display recess and a foldable display structure comprising a display panel and a cover layer with a variable thickness. The cover layer extends beyond the display panel edges and is directly attached to the housing via adhesive portions, eliminating the need for a bezel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bezel is added to protect the display panel, then the reliability of the display panel is improved, but the active display area is reduced and the aesthetic quality deteriorates
Solution Approach 1:
The invention extracts the protective function from the traditional bezel structure and relocates it to the cover layer extension portion. The cover layer extends beyond the display panel perimeter to form a protective barrier, while the adhesive portion secures this extended cover layer to the housing, eliminating the need for a separate bezel structure and maximizing the active display area.
Solution Approach 2:
The invention merges the protective function with the cover layer itself by extending it beyond the display panel edges. This integration combines the display cover function with the protective border function into a single component, eliminating the need for a separate bezel and achieving both protection and aesthetic quality.
2Reliability
If a bezel is added to protect the display panel, then the reliability of the display panel is improved, but the aesthetic quality deteriorates due to the borderless display requirement
Solution Approach 1:
The protective function is extracted from the traditional visible bezel and transferred to the cover layer extension, which is positioned behind the display panel perimeter. This allows the front view to maintain a true borderless aesthetic while the extended cover layer provides protection from behind.
Solution Approach 2:
The extended cover layer acts as an intermediary protective element that is not visible from the front view. It provides protection against contaminants and damage while maintaining the aesthetic quality of the borderless display appearance from the user's perspective.
3Object-affected harmful factors
If the cover layer is extended beyond the display panel edges, then the protection against contaminants is improved, but the device complexity increases
Solution Approach 1:
The invention combines the cover layer with the protective barrier function by extending it beyond the display panel. This merging eliminates the need for separate protective structures and complex assembly processes, as the extended cover layer integrates multiple functions into a single component that can be manufactured and assembled more simply.
4Reliability
If adhesive portions are used to attach the extended cover layer, then the protection and sealing are improved, but the manufacturing precision requirements increase
Solution Approach 1:
The adhesive portion is designed to be applied between the extended cover layer and the housing structure, where the natural positioning and alignment features of the housing guide the adhesive application. This self-aligning design reduces the need for high-precision manual positioning during assembly, making the manufacturing process more tolerant and easier to control.

Function Achieved in This Case
This solution protects the display panel from damage and contaminants, maintains the active display area, and provides a borderless aesthetic, enhancing user experience and device functionality.
Implementation Method 1
a perimeter adhesive portion disposed between the extension portion of the cover layer and the ledge

AI summary
This document describes systems and techniques directed at bezel-less display mounts for foldable electronic devices. In aspects, a foldable electronic device includes a housing with a display recess that includes an inwardly projecting ledge. A foldable display structure, which includes a display panel and a cover layer, is positioned in the display recess. In aspects, the cover layer includes a variable thickness along at least one dimension. The cover layer defines an extension portion that extends beyond one or more edges of the display panel. A back adhesive portion is disposed between the bottom face of the display panel and the bottom of the housing and a perimeter adhesive portion is disposed between the extension portion of the cover layer and the ledge. In this way, the foldable electronic device can do away with a bezel (e.g., display trim) that would otherwise surround a perimeter of the display panel.
