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
A novel arrangement of Mini-LEDs in a staggered pattern with specific positioning and electrode orientations, reducing edge luminance and simplifying wiring to improve image quality and reduce noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If Mini-LEDs are arranged in a conventional grid pattern, then the display screen can be manufactured with standard processes, but the light mixing effect is poor causing light shadows and peripheral blueness
Solution Approach 1:
The patent applies asymmetry by arranging Mini-LEDs in a staggered pattern where odd-row LEDs and even-row LEDs are offset from each other, creating an asymmetric layout that improves light mixing uniformity and reduces peripheral blueness compared to conventional symmetric grid arrangements
Solution Approach 2:
The patent introduces a new dimension to the arrangement by adding vertical offset between rows in addition to horizontal positioning, transforming the conventional 2D grid into a 3D-staggered configuration that enhances light diffusion and mixing effects
2Illumination intensity
If Mini-LEDs are arranged in a staggered pattern to improve light mixing, then light mixing uniformity is enhanced, but the arrangement complexity increases
Solution Approach 1:
The patent segments the display into odd rows and even rows with different horizontal positioning, allowing each segment to be designed and manufactured separately while achieving improved overall light mixing uniformity through the staggered combination
Solution Approach 2:
The patent applies local quality by giving different horizontal positions to LEDs in odd rows versus even rows, where each local arrangement is optimized for its specific position to achieve uniform light mixing across the entire display surface
3Reliability
If complex internal wiring is used to connect Mini-LEDs, then all LEDs can be connected, but noise and resonance occur due to reverse currents
Solution Approach 1:
The patent merges adjacent Mini-LEDs into groups that share common connection nodes, reducing the total number of wiring paths and minimizing reverse current loops that cause noise and resonance while maintaining reliable connections
Solution Approach 2:
The patent extracts and eliminates unnecessary wiring paths by optimizing the connection topology to remove redundant conductors that would carry reverse currents, thereby reducing noise and resonance while maintaining essential connections
