Cover Lens Interlayer Support for Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with cover lenses lack support underneath, making them prone to breakage when hit by external forces, and resulting in potential flying debris issues.
Innovation Solution
A display device design that includes a frame with a supporting surface, a display unit with a gap between its edge and the frame, a cover lens with specific portions overlapping the display unit, gap, and frame surface, and an interlayer in contact with the cover lens and overlapping the gap to provide support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the cover lens is placed directly on the display unit without support underneath, then the assembly structure is simple, but the cover lens is prone to breakage when hit by external forces
Solution Approach 1:
An interlayer is introduced between the cover lens and the display unit/frame to provide support underneath the cover lens. This intermediary layer prevents direct contact while providing the necessary structural support to reduce breakage risk when external forces are applied to the cover lens.
Solution Approach 2:
The interlayer is positioned beforehand underneath the cover lens to provide cushioning and support before external forces are applied. This pre-positioned support structure prevents the cover lens from breaking when subjected to impact or external pressure.
2Ease of manufacture
If the cover lens is placed directly on the display unit without support underneath, then the manufacturing process is simple, but flying debris may occur after breakage
Solution Approach 1:
The interlayer serves as a mediator that provides underlying support to the cover lens, preventing it from shattering into flying debris when broken. The interlayer acts as a containment structure that keeps broken pieces from scattering.
Solution Approach 2:
The interlayer provides beforehand cushioning support that prevents catastrophic failure of the cover lens. When external forces are applied, the interlayer absorbs and distributes the impact, preventing the cover lens from breaking into dangerous flying debris.
3Strength
If an interlayer is added to support the cover lens underneath, then the structural strength is improved, but the device complexity increases
Solution Approach 1:
The interlayer serves multiple functions simultaneously: it provides structural support underneath the cover lens, acts as a cushioning layer to prevent breakage, and can also serve as an adhesive layer to bond components together. This multi-functionality reduces the need for additional separate components.
Solution Approach 2:
The interlayer combines multiple functional elements into a single integrated component. Instead of having separate support structures, cushioning layers, and adhesive elements, the interlayer merges these functions into one element that provides comprehensive support and protection for the cover lens.

AI summary
A display device is provided. The display device includes a frame, a display unit, a cover lens and an interlayer. The frame has a supporting surface. The display unit is disposed on the frame and has at least one edge. There is a gap between the edge and the frame. The cover lens is disposed on the display unit and includes a first portion, a second portion and a third portion. The first portion overlaps the display unit. The second portion overlaps the gap. The third portion overlaps the supporting surface of the frame. The interlayer is in contact with the surface of the cover lens facing the frame and at least overlaps the gap.
