Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for integrating color conversion materials in microdevices face challenges in effectively coupling light and enhancing color conversion efficiency, as existing technologies lack optimal integration strategies for color conversion particles with device layers and substrates.
Innovation Solution
The method involves integrating color conversion particles on at least one surface of a microdevice with a light coupling layer between the particles and device layers, and forming microdevice layers on top of these particles, using various configurations such as embedding in films, bonding, and forming seed layers for optimal light coupling and reflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If color conversion particles are integrated directly on device layers without a light coupling layer, then the device structure is simpler, but light conversion efficiency is reduced
Solution Approach 1:
A light coupling layer is introduced as an intermediary between the color conversion particles and the device layers. This layer improves light extraction and coupling efficiency, enabling better light conversion performance while maintaining a manageable device structure through standardized layer integration processes
2Reliability
If color conversion particles are placed on both surfaces of the microdevice, then color conversion performance is enhanced, but device complexity increases
Solution Approach 1:
The color conversion function is segmented and distributed across both top and bottom surfaces of the microdevice. Each surface independently contributes to color conversion, allowing the system to achieve enhanced performance through distributed functionality rather than a single complex integration point
3Use of energy by moving object
If color conversion particles are embedded in films with reflective layers, then light reflection and conversion are improved, but manufacturing precision requirements increase
Solution Approach 1:
The color conversion particles are embedded in films and positioned relative to reflective layers through preliminary structuring steps. The reflective layers are formed with predetermined patterns and positions, allowing subsequent particle embedding to occur at standardized interfaces, which manages precision requirements through process sequencing
