Display Panel Connection State Confirmation for Flexible Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in ensuring safe and proper connection between flexible or rollable display panels and their driving modules to prevent short circuits and fires, particularly due to external forces or user errors, which can lead to connection defects.
Innovation Solution
A display apparatus with a connection state confirmation unit that outputs a signal indicating the connection status between the display panel and the driving device, allowing power to be supplied only when a normal connection is confirmed, and includes multiple power supplies to manage power distribution efficiently across the display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection confirmation is implemented before power supply, then safety and reliability are improved, but device complexity increases due to additional confirmation circuits and control logic
Solution Approach 1:
The connection confirmation unit checks the connection state between display panel and driving module before the power supply unit activates power. This preliminary verification ensures that power is only supplied when a proper connection is detected, preventing short circuits and safety hazards while maintaining a relatively simple system architecture.
Solution Approach 2:
A connection confirmation unit is introduced as an intermediary component between the power supply unit and the display panel. This mediator checks connection status and provides feedback to control power supply, adding safety functionality without requiring complete redesign of the power delivery system.
2Productivity
If multiple power supplies are used for different display areas, then power distribution efficiency is improved, but device complexity increases due to multiple power supply units
Solution Approach 1:
The display panel is divided into multiple display areas, with each area assigned to a separate power supply unit. This segmentation allows independent power management for different regions, improving power distribution efficiency and enabling localized power control without requiring a complete overhaul of the power supply architecture.
Solution Approach 2:
Each power supply unit is designed to be capable of supplying power to its designated display area independently. The modular power supply units can function autonomously, providing universal power delivery capability that scales with the display panel configuration while maintaining manageable system complexity.
