Display Middle Cabinet Overlapping Mounting Units Corner Light Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The light leakage phenomenon in the corner area of display apparatuses, particularly in liquid crystal display devices, causes visual inconvenience and is difficult to address without additional processes or structures.
Innovation Solution
A display apparatus design featuring a middle cabinet with overlapping mounting units that form a 'T'-shaped cross section, including a first and second mounting unit with varying heights and a hole, which are integrated and bonded to the display panel using foam pads, effectively preventing light leakage by eliminating gaps in the corner area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If mounting units are arranged separately in the corner area, then the manufacturing process is simple, but light leakage occurs between the mounting units
Solution Approach 1:
The patent merges two separate mounting units into a single integrated mounting unit that covers the corner area. The first mounting unit and second mounting unit are combined into one piece that extends along both the first long side and the first short side of the display panel, eliminating the gap between them and preventing light leakage while maintaining manufacturing simplicity.
2Object-affected harmful factors
If additional structures are added to prevent light leakage, then light leakage is improved, but the device complexity increases
Solution Approach 1:
Instead of adding separate light-blocking structures or additional mounting units, the patent combines the mounting functions into a single integrated unit. This merging approach prevents light leakage through the natural coverage of the unified mounting structure without requiring extra components or complex assemblies.
3Object-affected harmful factors
If the mounting units overlap in the corner area, then light leakage is prevented, but the manufacturing process becomes more complex
Solution Approach 1:
The patent resolves the manufacturing complexity issue by merging the overlapping mounting units into a single integrated component. The unified mounting unit is designed to extend along multiple sides of the display panel, incorporating what would have been separate overlapping units into one manufacturable piece, thus preventing light leakage without complicating the manufacturing process.
