Display Panel Light-Absorbing Layer for Seam Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Spliced display apparatuses often exhibit visual image discontinuities due to non-display areas at the periphery of display panels, which cannot be effectively eliminated, affecting the display quality of large-scale display boards.
Innovation Solution
Incorporating a light-absorbing layer with an optical density of 0.5 or more on the splicing surfaces of display panels to reduce the visibility of seams between adjacent panels, optionally combined with an optical auxiliary layer for further reduction in reflectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple display panels are spliced to form large-scale display boards, then the cost of installation and maintenance is reduced, but visual image discontinuities such as dark lines appear at the splicing seams
Solution Approach 1:
A light-absorbing layer is introduced as an intermediary component between adjacent display panels at the splicing seam. This layer absorbs stray light that would otherwise create visible discontinuities, thereby eliminating the harmful visual effect while preserving the modular spliced structure that provides cost advantages.
2Object-generated harmful factors
If light-absorbing layer is added to reduce seam visibility, then image discontinuity is reduced, but device complexity increases
Solution Approach 1:
The light-absorbing layer is implemented as a thin film or coating applied directly to the splicing surface of the display panels. This thin-film approach effectively reduces seam visibility without adding significant structural complexity, thickness, or mechanical complexity to the display apparatus.
3Object-generated harmful factors
If optical auxiliary layer with low reflectivity is added, then reflectivity is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The optical properties of the auxiliary layer are optimized by controlling parameters such as material composition, layer thickness, and refractive index to achieve low reflectivity. By carefully adjusting these parameters, the desired optical performance is achieved while keeping manufacturing within standard precision ranges.
