Display Assembly Glass-Frame Bonding for Narrow-Bezel Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panel fixation methods, particularly for panels with small black edge areas, result in reduced screen-to-body ratio and visible frame presence, affecting display quality and user experience.
Innovation Solution
A display assembly design where the display panel is indirectly fixed to a frame via a protective glass, with a light shielding layer on the glass edge and a bonding agent in a groove, allowing the glass to extend beyond the panel, enhancing installation space and reducing frame visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display panel is directly bonded to the frame using double sided tape, then the fixation is simple and reliable, but the screen-to-body ratio is reduced and frame visibility increases
Solution Approach 1:
The patent introduces a protective glass as an intermediary component between the display panel and the frame. The protective glass is bonded to the frame, and the display panel is bonded to the protective glass, creating an indirect fixation path. This mediator allows the display panel to be positioned without direct contact with the frame, maximizing the screen area while maintaining reliable fixation through the protective glass-frame connection.
2Ease of manufacture
If the black edge area width is increased to facilitate bonding with the frame, then the bonding is easier to achieve, but the display area is reduced and screen-to-body ratio decreases
Solution Approach 1:
The protective glass serves as a mediator that provides a bonding interface with the frame independent of the display panel's black edge area width. The protective glass can be bonded to the frame using its extended edges, while the display panel is subsequently bonded to the protective glass. This decouples the bonding ease requirement from the display area constraint, allowing narrow black edge areas while maintaining easy bonding through the protective glass-frame connection.
3Area of moving object
If the protective glass extends beyond the display panel to increase installation space, then the screen-to-body ratio is improved, but the light shielding becomes more difficult
Solution Approach 1:
The patent applies local quality by creating a light shielding layer specifically at the edge area of the protective glass where light leakage is most likely to occur. The light shielding layer is positioned at the periphery of the protective glass, providing localized light blocking functionality only where needed, rather than covering the entire glass surface. This maintains the extended protective glass design for maximum screen area while preventing light leakage at the critical edge regions.
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
Increases screen-to-body ratio and improves user experience by minimizing frame visibility and ensuring seamless integration of the display panel, while maintaining display quality and structural integrity.
Implementation Method 1
the inner surface of the protective glass is bonded to a surface of a side wall of the frame by a bonding agent
Implementation Method 2
a light shielding layer on an edge area of the protective glass, the light shielding layer configured to shield a gap between the display panel and the frame

AI summary
The application relates to a display assembly and a manufacturing method for the display assembly. The display assembly comprises a frame (110), a display panel (120) and protective glass (130); and the display panel is attached onto the inner surface of the protective glass to form an integrated structure, an edge (132) of the inner surface of the protective glass extends beyond the display panel, and the edge of the inner surface of the protective glass is bonded to a surface of a side wall of the frame by a bonding agent (160). A display screen of the display assembly provided by the application does not need to be connected with the protective glass only by a black edge area, so that the installation mode is not influenced by a width of the black edge area of the display screen.
