Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display devices with multiple screens, there is a challenge in detecting and addressing failures in individual display panels, which can lead to incomplete or absent image display, affecting usage and functionality.
Innovation Solution
A display device configuration that includes multiple display panels with a protection plate, a transparent adhesive to secure them, and a detection circuit to identify abnormal signal outputs, allowing for the isolation and management of failed panels while maintaining image display on functional ones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display panels are used to display images independently, then the functionality and versatility of the display device is improved, but the risk of panel failure and the complexity of managing failures increases
Solution Approach 1:
The display device is divided into multiple independent display panels, each capable of displaying images independently. This segmentation allows individual panels to be managed separately, so that failure of one panel does not necessarily cause failure of the entire display system.
Solution Approach 2:
A detection circuit is provided that detects abnormal values of signals output from display panels and provides feedback information about panel status. This feedback mechanism enables real-time monitoring of panel health and allows the system to respond appropriately to detected failures.
2Reliability
If a detection circuit is added to detect abnormal signal outputs from display panels, then the reliability and fault detection capability is improved, but the device complexity increases
Solution Approach 1:
The detection circuit is integrated with the existing display panel structure, combining the detection function with the panel's signal output path. This merging approach allows failure detection without adding completely separate monitoring systems, thereby limiting the increase in overall device complexity.
3Strength
If display panels are secured with protection plates and transparent adhesive, then the physical protection and structural stability is improved, but the manufacturing process complexity increases
Solution Approach 1:
Protection plates are pre-positioned and secured with transparent adhesive before final assembly of the display device. This preliminary action ensures that panels are protected during subsequent manufacturing steps and reduces the risk of damage during assembly, thereby limiting the increase in manufacturing complexity.
