Borderless Display Apparatus Using Guide Frame Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LCD devices are limited in minimizing thickness and developing new designs due to the necessity of lower and upper cases and front and rear set covers, which increase thickness and restrict innovative design advancements.
Innovation Solution
A display apparatus design that removes the case and some portions of the set cover, utilizing a guide frame with a sealing member to seal the gap between the display panel and the set cover, formed by a double injection method using materials like rubber or thermoplastic urethane, to achieve a thinner and more aesthetically appealing borderless design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If case and set cover structures are used to protect and assemble the display apparatus, then structural integrity and protection are improved, but thickness increases and design flexibility is restricted
Solution Approach 1:
The patent removes the traditional case structure and extracts only the essential protective and assembly functions. The set cover is partially removed with openings at the front and side edges, eliminating unnecessary portions that increased thickness while maintaining structural integrity through the guide frame and sealing member integration.
Solution Approach 2:
The guide frame and sealing member are merged into a single integrated component that performs multiple functions: supporting the display panel, sealing gaps between the set cover and panel, and providing structural strength. This consolidation eliminates the need for separate case structures while maintaining protection and reducing thickness.
2Strength
If case and set cover are used for assembly and protection, then structural support is improved, but device complexity and number of parts increase
Solution Approach 1:
The guide frame and sealing member are combined into a single integrated part that replaces multiple traditional components (case, separate sealing elements, and mounting structures). This merger reduces the number of parts while maintaining structural support functionality.
Solution Approach 2:
The guide frame is designed as a multi-functional component that simultaneously provides structural support, panel positioning, gap sealing, and aesthetic border functions. This universality eliminates the need for multiple specialized parts, reducing overall device complexity.
3Object-affected harmful factors
If upper case and front set cover are used to cover the display panel edges, then protection is improved, but the border width increases and aesthetic design is limited
Solution Approach 1:
The patent removes the front set cover and upper case portions that extended beyond the display panel edges. By extracting these unnecessary covering elements, the border width is minimized while the guide frame and sealing member provide sufficient protection for the panel edges.
Solution Approach 2:
Protection is applied locally only where necessary - the guide frame and sealing member are positioned precisely at the gaps between the set cover and display panel. This localized protection approach eliminates excessive border width while maintaining adequate protection against harmful factors.
