Guide Frame Adhesive Coupling for Display Panel Impact Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flat panel display devices, such as LCDs, face limitations in slimming and design innovation due to the use of multiple case components that increase thickness and border widths, and create step heights, making it difficult to achieve a sleek aesthetic and minimize light leakage.
Innovation Solution
A display device design that removes certain case components and uses a guide frame with a coupling member featuring a main adhesive and a sub adhesive to maintain a constant interval between the display panel and the guide frame, preventing light leakage and enhancing impact absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple case components (front set cover, rear set cover, lower case, front case) are used to house and protect the display panel and backlight unit, then protection and housing functions are improved, but device thickness and border widths increase
Solution Approach 1:
The patent merges the functions of multiple separate case components (front set cover, rear set cover, lower case, front case) into a single integrated guide frame structure. This guide frame simultaneously provides housing, protection, and structural support functions that were previously distributed across multiple components, thereby reducing overall device thickness while maintaining protective functions.
Solution Approach 2:
The guide frame is designed as a multi-functional component that serves as both a structural support element and a protective housing. It integrates the functions of multiple specialized case components into one universal structure that provides housing, protection, and alignment functions, eliminating the need for separate dedicated components and reducing thickness.
2Reliability
If multiple case components are used to house and protect the display panel, then protection functions are improved, but border widths and step heights increase
Solution Approach 1:
By combining multiple case components into a single guide frame, the patent eliminates the interfaces and transitions between different components that create step heights and varying border widths. The merged structure provides a uniform, flush surface across the entire border area, removing visual disruptions while maintaining protection.
3Object-affected harmful factors
If the upper cover surrounds all peripheral portions of the upper substrate to prevent light leakage, then light sealing is improved, but step heights and border widths are enlarged
Solution Approach 1:
The patent extracts the light sealing function from the traditional upper cover component and relocates it to the guide frame structure. The guide frame incorporates specific sealing features (such as gaskets or sealed interfaces) that prevent light leakage without requiring the extensive surrounding coverage that creates step heights and enlarged borders.
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 design minimizes device thickness and border width, removes step heights, and maintains a constant interval for better impact absorption, while reducing light leakage and enhancing adhesive strength between components.
Implementation Method 1
a main adhesive member adhering the guide frame to the display panel
Implementation Method 2
a sub adhesive member adhered to the guide frame adjacently to the main adhesive member

AI summary
A display apparatus includes a display panel including an upper substrate and a lower substrate coupled to a rear surface of the upper substrate; a guide frame supporting the display panel, and a coupling member coupling the guide frame to the display panel. The coupling includes a main adhesive adhering the guide frame to the display panel, and a sub adhesive adhered to the guide frame adjacent to the main adhesive. Accordingly, the display panel can more readily absorb an impact applied thereto, thus enhancing the stability of the display panel.
