Integrated Plastic Frame for Display Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses require external frames for adhesive filling, which are not applicable to open cells without a front iron frame and burden the assembly process with material and procedural requirements.
Innovation Solution
An integrated plastic frame is developed, combining a first accommodating portion for the backlight module, a second accommodating portion for the panel, and an adhesive-restricting portion to form a sealed space for optical adhesive, simplifying assembly and reducing material needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an external frame is used for adhesive filling, then the adhesive can be properly contained and applied, but the device complexity increases and the assembly procedure becomes more burdensome
Solution Approach 1:
The patent merges the external frame function with the backlight module's plastic frame by integrating the adhesive-restricting portion into the existing frame structure. This eliminates the need for a separate external frame while maintaining adhesive containment, thereby reducing device complexity and assembly burden.
Solution Approach 2:
The plastic frame of the backlight module is designed to serve multiple functions: it provides structural support for the backlight module, accommodates the panel, and simultaneously acts as an adhesive-restricting portion to contain the optical adhesive. This multi-functionality eliminates the need for a dedicated external frame.
2Reliability
If a separate external frame is used for adhesive filling, then the adhesive application is controlled, but the material requirement and assembly procedure become burdensome
Solution Approach 1:
The adhesive-restricting portion is integrated into the backlight module's plastic frame, combining the adhesive application control function with the existing frame structure. This eliminates the need for a separate external frame and its associated assembly procedures, making manufacturing easier.
3Reliability
If an external frame is used for adhesive filling, then the adhesive can be properly applied, but it is not applicable to open cells without a front iron frame
Solution Approach 1:
The plastic frame is designed to serve as both the backlight module housing and the adhesive-restricting structure, making it universally applicable to different display configurations including open cells without front iron frames. The integrated design adapts to various panel types and display structures.

AI summary
A display apparatus includes a panel, a backlight module, a cover, an integrated plastic frame and an optical adhesive. The panel is disposed over the backlight module. The cover is disposed over the panel, which is located between the cover and the backlight module. The integrated plastic frame includes a first accommodating portion, a second accommodating portion and an adhesive-restricting portion. The second accommodating portion is coupled between the first accommodating portion and the adhesive-restricting portion. The combination of the first accommodating portion, the second accommodating portion and the adhesive-restricting portion is integrally formed. The first accommodating portion accommodates at least a portion of the backlight module, the second accommodating portion accommodates the panel, and the adhesive-restricting portion is coupled between the second accommodating portion and the cover to define an accommodating space together with the cover and the panel. The optical adhesive is disposed in the accommodating space.
