Display Protection Assembly for Thin Bezel Speaker Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The external protective cover of a display screen and chip-on-film packaging for a flexible printed circuit board protrude from the display screen, affecting the overall structure's compactness and user's visual experience.
Innovation Solution
A protection assembly is designed with a decorative layer, support, and buffer layer, where the decorative layer is bonded to the support and abuts against the screen surface through a buffer layer, minimizing thickness and incorporating a speaker mesh structure to maintain functionality while reducing protrusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an external protective cover and COF packaging are added to protect the display screen, then the display screen is protected, but the overall structure becomes thick and protrudes from the display screen
Solution Approach 1:
The patent merges the protective cover and COF packaging into a single integrated protection assembly. The decorative layer, support, and buffer layer are combined into one unified structure that provides both protection and speaker functionality, eliminating the need for separate external protective covers and reducing overall thickness.
Solution Approach 2:
The protection assembly is designed to serve multiple functions simultaneously: it protects the display screen, houses the speaker, provides structural support, and maintains the overall thin profile. The decorative layer with speaker mesh structure integrates protective, acoustic, and structural roles into a single component.
2Reliability
If the protective cover is made thick to provide adequate protection, then the display screen is well protected, but the visual experience of the user is affected
Solution Approach 1:
The patent employs thin film structures including a thin decorative layer (0.1-0.5mm), thin support structure, and thin buffer layer (0.1-0.3mm) that collectively provide adequate protection while maintaining a compact, flush profile that does not protrude from the display screen surface.
Solution Approach 2:
The protection assembly uses composite material construction combining decorative layer material, support material, and buffer layer material with different properties to achieve both adequate protection and thin profile. The composite structure optimizes the balance between protection strength and overall thickness.
3Stability of the object's composition
If the first surface of the support protrudes from the screen surface to provide adequate support, then the support structure is stable, but the thickness of the protection assembly increases
Solution Approach 1:
The support structure transitions from a protruding three-dimensional configuration to a flush, planar configuration where the first surface is coplanar with or recessed relative to the screen surface. This dimensional change eliminates protrusion while maintaining structural stability through the integrated decorative layer and buffer layer.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively reduces the thickness of the display screen assembly, enhances user experience by allowing perception of a front speaker, and maintains display performance without light transmission or visible color differences.
Implementation Method 1
A first part of the decorative layer is bonded to a first surface of the support through a first adhesive layer
Implementation Method 2
a second part of the decorative layer abuts against a screen surface through the buffer layer

AI summary
A protection assembly of the electronic device is disposed along a side edge of a display screen assembly, and includes a decorative layer, a support, and a buffer layer. The support is located on a side of the display screen assembly, and is fastened to the side edge of the display screen assembly. The decorative layer is located on an outer side of the display screen assembly and the support. A first part of the decorative layer is bonded to a first surface of the support through a first adhesive layer, a second part of the decorative layer abuts against a screen surface through the buffer layer, and the first surface is a surface that is on the support and that is located on a side of the screen surface of the display screen assembly.
