Integrated Cover Adhesive-Restricting Portion for Display Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses require an external frame for adhesive filling, leading to size tolerance issues and adhesive leakage, as well as increased material and assembly burdens.
Innovation Solution
A display apparatus with a cover that integrates an adhesive-restricting portion, eliminating the need for a separate frame by forming a sealed space with the display module, using a connecting element like double-sided tape to hold the optical adhesive, and optionally incorporating rib reinforcement structures for enhanced structural strength and adhesive retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an external frame is used for adhesive filling, then adhesive can be contained, but the frame has size tolerances that cause gaps and adhesive leakage
Solution Approach 1:
The patent merges the frame function and cover function into a single integrated cover structure. The cover includes a cover body and an adhesive-restricting portion that forms a seamless integration, eliminating the gap between separate frame and cover components. This integration ensures reliable adhesive containment without the manufacturing precision issues of assembling separate parts.
Solution Approach 2:
The cover is designed to perform multiple functions: it serves as both the cover plate protecting the display module and as the adhesive-restricting structure (replacing the traditional frame). The adhesive-restricting portion with its inner wall and bottom surface creates a sealed space that contains adhesive, while the cover body provides protection, achieving multi-functionality in a single component.
2Reliability
If an external frame is used for adhesive filling, then adhesive can be contained, but material requirements and assembly procedures increase
Solution Approach 1:
The patent combines the frame and cover into one integrated component, reducing the total number of parts. The cover includes both the cover body and the adhesive-restricting portion, eliminating the need for a separate frame assembly step. This simplification reduces material requirements and streamlines the assembly procedure while maintaining reliable adhesive containment.
Solution Approach 2:
The cover performs dual functions as both a protective cover and an adhesive-containing structure. By integrating the adhesive-restricting portion into the cover, the design eliminates the separate frame component, thereby reducing device complexity and assembly procedures while achieving the same adhesive containment reliability.
3Ease of manufacture
If a separate frame and cover are assembled, then adhesive filling is possible, but the joint between frame and cover causes adhesive leakage
Solution Approach 1:
The patent eliminates the joint between frame and cover by merging these functions into a single integrated cover structure. The adhesive-restricting portion forms a continuous sealed space with the cover body, removing the interface where adhesive leakage typically occurs. This integration maintains ease of manufacture through simple assembly while ensuring reliable adhesive containment without leakage.
4Manufacturing precision
If an external frame is used, then adhesive space is defined, but the frame adds weight and material consumption
Solution Approach 1:
The cover serves dual purposes as both a protective cover and an adhesive-space-defining structure. The adhesive-restricting portion with its inner wall and bottom surface creates the necessary adhesive containment space, eliminating the need for a separate frame. This integration reduces weight and material consumption while maintaining precise adhesive space definition.
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
This integration simplifies the assembly process, reduces material requirements, prevents adhesive leakage, and enhances process yield and product competitiveness by allowing the cover to function as both a frame and a cover plate simultaneously.
Implementation Method 1
The connecting element is connected between the lower surface of the adhesive-restricting portion and the surface of the display module
Implementation Method 2
Optical adhesives, such as optical clear resins (OCR), are special adhesives designed for the binding of transparent optical components. The optical adhesive fills a gap formed between a panel and a transparent cover to enhance a contrast of a display apparatus

AI summary
A display apparatus includes a display module, a cover, a connecting element and an optical adhesive. The cover is disposed over the display module, and includes a cover portion and an adhesive-restricting portion. The adhesive-restricting portion is protruded from a periphery of a bottom side of the cover portion. The adhesive-restricting portion includes a lower surface facing a surface of the display module. The connecting element is connected between the lower surface of the adhesive-restricting portion and the surface of the display module, and defines an accommodating space together with the cover and the display module. The optical adhesive is disposed in the accommodating space.
