Detachable Light Emitting Substrate for Scalable Display Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional scalable displays face challenges in maintainability, as defects in individual light emitting elements require replacement of the entire display device, leading to inefficiencies in repair and maintenance.
Innovation Solution
A light emitting device configuration that includes a substrate with light emitting elements, a frame, and an actuator that vibrates the substrate, allowing for detachability of the substrate from the actuator, thereby facilitating easy replacement and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the substrate is integrated with the actuator, then the structural stability is improved, but the ease of repair deteriorates
Solution Approach 1:
The light emitting device is divided into separate modules: the substrate containing light emitting elements and the actuator for vibration. This segmentation allows the substrate to be detached from the actuator, enabling easy replacement of defective substrates while maintaining structural integrity through the frame that holds both components.
2Ease of repair
If the substrate is detachable from the actuator, then the ease of repair is improved, but the device complexity increases
Solution Approach 1:
The frame serves multiple functions: it provides structural support, holds the substrate, and secures the actuator. By merging these functions into a single component, the design achieves ease of repair through detachability without significantly increasing overall device complexity.
3Reliability
If the entire display device is replaced, then the reliability is improved, but the loss of time increases
Solution Approach 1:
The display device is segmented into replaceable modules, specifically the substrate module that can be detached from the actuator. When defects occur in light emitting elements, only the substrate needs replacement rather than the entire display device, significantly reducing maintenance time while ensuring reliability.
