Mini-LED Module Layout for Uniform Light Mixing and Low Noise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Mini-LED arrangements suffer from poor light mixing effects, leading to issues like light shadows and peripheral blueness, and complex internal wiring that causes noise and resonance due to reverse currents.
Innovation Solution
The arrangement of light-emitting elements in a staggered manner with specific positional relationships and electrode orientations reduces edge luminance and simplifies wiring, improving image quality and reducing noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If light-emitting elements are arranged in a conventional grid pattern, then manufacturing is simple, but light mixing is poor causing light shadows and peripheral blueness
Solution Approach 1:
The patent applies asymmetry by arranging light-emitting elements in a staggered pattern rather than a symmetric grid. Specifically, odd-numbered and even-numbered rows are offset from each other, creating an asymmetric distribution that improves light mixing by preventing regular interference patterns and reducing light shadows while maintaining manufacturing feasibility.
2Reliability
If light-emitting elements are arranged in a staggered manner to improve light mixing, then light mixing uniformity improves, but device complexity increases due to electrode orientation requirements
Solution Approach 1:
The patent applies local quality by differentiating electrode orientations based on row position. Odd-numbered rows have electrodes oriented in one direction while even-numbered rows have electrodes oriented in the opposite direction. This localized differentiation optimizes light mixing in each row while managing overall device complexity through a systematic pattern.
Solution Approach 2:
The patent segments the light-emitting element array into odd-numbered rows and even-numbered rows with different electrode orientations. This segmentation allows independent optimization of each row type while maintaining overall system coherence, improving light mixing uniformity without requiring complete redesign of the entire electrode system.
3Ease of manufacture
If complex internal wiring is used to support conventional arrangements, then manufacturing is easier, but noise and resonance increase due to reverse currents
Solution Approach 1:
The asymmetric staggered arrangement of light-emitting elements with alternating row orientations reduces the formation of regular current loops that cause resonance. By breaking the symmetry of conventional grid arrangements, the patent minimizes harmful electromagnetic interference and noise while maintaining a manufacturable wiring structure.
