Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transparent light-emitting displays face challenges in securely mounting electronic devices like LEDs, as they are prone to detachment due to warping or external forces, which affects their stability and functionality.
Innovation Solution
A transparent light-emitting display film is developed with a transparent substrate, through holes for embedding light-emitting devices, and a connection member to electrically link the devices, ensuring secure attachment and minimizing protrusion, along with a method that includes applying a resin layer, forming electrode patterns, and creating holes perpendicular to the substrate for mounting and connecting the devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a transparent light-emitting display uses a film-like substrate with mounted electronic devices, then the display achieves transparency and flexibility, but the electronic devices are prone to detachment due to warping or external forces
Solution Approach 1:
The light-emitting device is inserted into a through hole formed in the transparent substrate, nesting the device within the substrate structure. This embedding approach secures the device against detachment while maintaining the transparency and flexibility of the film-like substrate.
Solution Approach 2:
The through hole is formed in the transparent substrate before the light-emitting device is mounted. This preliminary preparation of the mounting structure ensures proper positioning and secure attachment of the device, preventing warping and detachment issues.
2Length of stationary object
If electronic devices are mounted on a transparent substrate, then the display can be made thinner and more transparent, but the devices may warp or bend under external forces
Solution Approach 1:
By nesting the light-emitting device within the through hole of the transparent substrate, the device is mechanically supported from all sides, preventing warping or bending under external forces while maintaining thin overall display thickness.
Solution Approach 2:
The connection member combines the transparent substrate and the light-emitting device into a composite structure that distributes mechanical stress, enhancing structural stability while maintaining the thin profile and transparency of the display.
3Reliability
If a through hole is formed to penetrate the transparent substrate for mounting light-emitting devices, then secure mounting is achieved, but the manufacturing process becomes more complex
Solution Approach 1:
The through hole is formed in the transparent substrate before device mounting, allowing for precise positioning and alignment. This preliminary preparation simplifies the subsequent device insertion and connection processes, reducing overall manufacturing complexity despite the additional step.
