Solution Overview
Problem
The existing mini LED display devices face complications in assembly and low production efficiency due to the difficulty in placing support columns between the light source and optical film, which affects the optical effect and user experience.
Innovation Solution
A light-transmitting magnetic structure is introduced between the light source plate and the optical film, providing a magnetic support force to replace the traditional support column, ensuring the optical film is properly supported and maintaining a sufficient light mixing distance, thus simplifying the assembly process and enhancing production efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If support columns are provided between the backplane and optical film to provide light mixing distance, then the optical effect is improved, but the assembly process becomes complicated and production efficiency decreases
Solution Approach 1:
The patent removes the support column structure from the display device. Instead of using physical support columns between the backplane and optical film, the patent uses the magnetic attraction between the light source plate and optical film to maintain the necessary distance and provide light mixing, thereby eliminating the complex support column assembly process while preserving the optical effect
Solution Approach 2:
The patent replaces the mechanical support column system with a magnetic field-based support system. The magnetic attraction force between the magnetically responsive light source plate and the optical film substitutes for the mechanical support columns, simplifying the structure while maintaining the required light mixing distance
2Reliability
If support columns are provided between the backplane and optical film, then the optical film is supported, but the production efficiency is reduced
Solution Approach 1:
The patent extracts and removes the support column component from the assembly process. The magnetic attraction between the light source plate and optical film inherently provides the necessary support and spacing, eliminating the need for separate support columns and simplifying production
Solution Approach 2:
The patent implements a self-supporting system where the magnetic attraction between the light source plate and optical film automatically maintains the required distance and supports the optical film without external support structures, enabling self-alignment and simplifying assembly
3Illumination intensity
If mini LED backlight technique is introduced to achieve ultra-thin and high-dynamic contrast, then the display performance is improved, but the assembly process becomes more complicated due to difficulty in placing support column
Solution Approach 1:
The patent replaces the mechanical support column system with magnetic attraction to maintain the ultra-thin profile of mini LED displays. The magnetic field provides the necessary spacing and support without requiring complex mechanical structures, making the mini LED assembly process simpler while maintaining high display performance
Solution Approach 2:
The light source plate in the patent serves multiple functions: it provides light emission for display, contains magnetic materials for magnetic attraction, and acts as a support structure replacing traditional support columns. This multi-functionality simplifies the overall assembly process while maintaining mini LED display performance
