Convex Lens Groove for Display Panel Splicing Seam
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current splicing LCDs suffer from a black seam issue at the junction of adjacent display panels, which negatively impacts display quality due to the inability to emit light in the splicing area.
Innovation Solution
A display module design featuring two adjacent display panels spliced at different directions, with a groove and convex lens portion between them, where the convex lens's projection covers the splicing area, utilizing a light-gathering effect to ensure light emission across the seam, thereby eliminating the black seam and enhancing display effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display panels are spliced to achieve medium and large-size screens, then the display size is increased, but a black seam is generated at the splicing location resulting in poor display effects
Solution Approach 1:
A convex lens is introduced as an intermediary optical element at the splicing seam between two display panels. The convex lens focuses light from the conventional display area onto the splicing display area, enabling light emission at the seam and eliminating the black seam defect while maintaining the multi-panel configuration for large display size
Solution Approach 2:
The convex lens adds an optical dimension to the splicing structure by focusing light rays from the conventional display area onto the splicing display area. This optical dimensionality transforms the splicing seam from a light-blocking boundary into a light-emitting region, resolving the illumination issue without compromising the spatial arrangement of display panels
2Illumination intensity
If a convex lens portion is added between display panels to converge light into the splicing area, then light emission at the seam is improved, but the device structure becomes more complex
Solution Approach 1:
The display module is segmented into functional regions: conventional display area, splicing display area, and groove structures. The convex lens is positioned within the groove at the splicing seam, creating a modular structure where the optical element is integrated into the existing panel architecture rather than adding a completely separate system
Solution Approach 2:
The convex lens structure is merged with the groove formation between display panels. The lens is disposed within the groove that is already part of the panel assembly structure, combining the optical function with the existing mechanical structure to minimize additional complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively converges light from the conventional display area into the splicing area, eliminating the seam and improving the overall display module's performance by ensuring continuous light emission across the splicing position.
Implementation Method 1
a convex lens portion disposed between two display panels which are spliced, and light in the conventional display area of the display panel can be further converged into a splicing display area by utilizing light-gathering effect of the convex lens portion
