Direct Rear Cover Coupling for Display Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses have complex coupling structures for front and rear covers, leading to increased manufacturing costs and non-display areas, which are problematic for multi-display setups aiming to improve picture quality.
Innovation Solution
A simplified coupling structure where the rear cover is directly attached to the side surface of the display module, using press-formed metal and strategically placed coupling holes and through holes, eliminating the need for a front cover and reducing non-display areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional coupling structure with front cover and rear cover is used, then the display apparatus has a complete enclosure structure, but the structure becomes complicated and manufacturing costs increase
Solution Approach 1:
The patent removes the front cover from the display apparatus structure, extracting only the necessary rear cover that couples directly to the display module. This eliminates the complex front cover coupling mechanism while maintaining adequate protection and structural integrity through the simplified rear cover design with integrated coupling holes.
Solution Approach 2:
The rear cover is designed to directly couple with the display module through integrated coupling holes that align with holes in the display module. This merging of the rear cover and display module coupling eliminates the need for separate front and rear cover assembly, simplifying the overall structure and reducing manufacturing complexity.
2Area of stationary object
If a conventional coupling structure with front cover and rear cover is used, then the display apparatus has complete enclosure, but the non-display area increases which degrades picture quality in multi-display setups
Solution Approach 1:
The rear cover is designed with segmented coupling holes positioned at specific locations that allow precise alignment with the display module. This segmentation enables the rear cover to couple efficiently without requiring excessive overlap or non-display area, thereby minimizing the bezel width and improving picture quality in multi-display configurations.
3Device complexity
If the rear cover is directly coupled to the display module side surface, then the structure is simplified and manufacturing cost decreases, but the coupling strength may be reduced
Solution Approach 1:
The rear cover incorporates multiple coupling holes positioned at strategically located points on the display module side surface. This local quality approach concentrates the coupling strength at specific critical points rather than distributing it uniformly, ensuring adequate mechanical strength while maintaining the simplified direct coupling structure and reducing overall manufacturing complexity.
