Backlight Module Narrow Bezel Design via Integrated Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices face limitations in achieving a narrow bezel design due to the width of the cover plate frame, which is restricted by the dispensed adhesive and fastening buckle, making it difficult to reduce the total frame width below 1.9 mm.
Innovation Solution
The proposed backlight module incorporates a backboard with a fixing member extending along a direction away from the light source component, eliminating the need for a fastening buckle, and includes a frame member to secure the light source component, allowing direct connection to the display device's middle frame without increasing the frame width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fastening buckle is used to secure the backlight module, then the light source component is reliably fixed, but the total frame width increases making narrow bezel design difficult
Solution Approach 1:
The patent combines the fastening function into the backboard structure itself by adding fixing members directly to the backboard. This merges the previously separate fastening buckle component with the backboard, eliminating the need for an additional fastening component and thereby reducing the overall frame width while maintaining fixing reliability.
Solution Approach 2:
The patent extracts the fastening function from the separate fastening buckle and integrates it into the backboard through fixing members. This extraction allows the removal of the dedicated fastening buckle component, reducing the frame width while preserving the necessary securing function.
2Length of stationary object
If the frame width is reduced for narrow bezel design, then the aesthetic appearance is improved, but the assembly complexity increases due to space constraints
Solution Approach 1:
By merging the fastening function into the backboard structure, the patent reduces the number of separate components that need to be assembled. This integration simplifies the assembly process despite the reduced frame width, as fewer parts need to be handled and positioned in the constrained space.
3Reliability
If a separate fastening buckle is used, then the light source component is securely fixed, but the number of components increases
Solution Approach 1:
The patent merges the fastening function with the backboard by incorporating fixing members directly into the backboard structure. This eliminates the need for a separate fastening buckle component, reducing the total number of components while maintaining reliable fixation of the light source component.
Solution Approach 2:
The backboard is given multiple functions: it serves as the structural support base and simultaneously provides the fixing function through its integrated fixing members. This multi-functionality eliminates the need for dedicated fastening components, reducing overall component count.
