Reflecting Wall in Light Bar Gaps for Splicing Display Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The large difference in emission angles between light bars and display panels in splicing display screens leads to suboptimal display effects due to mismatched luminous effects, causing black edges and affecting overall display integrity.
Innovation Solution
Incorporating a reflecting wall in the gaps between light emitting elements of the light bar, which reduces the emission angle of the light bar to match the emission angle of the display panel, enhancing compatibility and display quality by reflecting side light upwards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a light bar is attached to eliminate black edges, then the black edge phenomenon is reduced, but the emission angle mismatch between light bar and display panel worsens the overall display effect
Solution Approach 1:
A reflecting wall structure is introduced as an intermediary component between the light emitting elements and the external environment. This reflecting wall redirects the side light from the light bar towards the display panel, serving as a mediator that bridges the emission angle mismatch between the light bar and display panel, thereby improving both the black edge elimination and the emission angle compatibility
Solution Approach 2:
The emission angle parameter of the light bar is modified by introducing the reflecting wall structure. The reflecting wall changes the light distribution pattern and effective emission angle of the light bar, making it compatible with the display panel's emission angle characteristics, thus resolving the angle mismatch problem while maintaining the black edge elimination function
2Ease of manufacture
If display panels are spliced to avoid excessive size, then manufacturing difficulty is reduced, but splicing slits create display integrity issues
Solution Approach 1:
The light bar is positioned to cover the splicing slits between display panels, extracting and addressing the display integrity issue at the specific location of the splicing joints. By placing the light bar over the splicing slits, the invention eliminates the visual impact of the slits while maintaining the benefits of spliced panel construction
Solution Approach 2:
The light bar serves multiple functions: it eliminates black edges on the display panel, covers splicing slits to maintain display integrity, and provides additional illumination. This multi-functionality allows a single component to address multiple issues simultaneously, including both the black edge phenomenon and the splicing slit visibility problem
