Solution Overview
Problem
Conventional flexible display modules rely solely on an external power source and lack self-driving capability and shock resistance, making them unstable and vulnerable to external shocks.
Innovation Solution
Incorporating a built-in battery and a printed circuit board to connect the battery to both the display unit and external power source, along with a graphite heat-radiating sheet and optional cooling fan to manage heat and enhance shock resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a built-in battery is added to enable independent operation, then self-driving capability is improved, but device complexity increases
Solution Approach 1:
The battery is integrated directly into the display module structure, merging the power supply function with the display unit. The battery, printed circuit board, and display components are combined into a single integrated assembly, eliminating the need for separate external power supply equipment and reducing overall system complexity despite adding self-driving capability.
Solution Approach 2:
The printed circuit board serves multiple functions: it connects the battery to the display unit for power supply, connects to external power sources for charging, and provides structural support. This multi-functionality reduces the need for additional components, maintaining simplicity while enabling both independent operation and external charging capabilities.
2Temperature
If a heat-radiating sheet and cooling device are added to manage heat, then temperature control is improved, but device complexity increases
Solution Approach 1:
The heat-radiating sheet is integrated into the existing module structure, combining thermal management functionality with the display assembly. The cooling device is similarly integrated, merging temperature control with the overall module design rather than adding separate external cooling systems.
Solution Approach 2:
The heat-radiating sheet acts as an intermediary thermal management component between the battery and the environment. It facilitates heat dissipation through its radiating properties without requiring complex active cooling systems, providing passive thermal management that simplifies the overall design.
3Volume of moving object
If the battery is made as a sheet extending parallel to the panel, then space utilization is improved, but manufacturing precision requirements increase
Solution Approach 1:
The battery is constructed as a flexible sheet that can be conformally integrated into the display module. This thin-film battery structure maximizes space utilization by extending parallel to the panel in a flexible format, allowing it to adapt to the module's geometry while maintaining manufacturability through established flexible battery fabrication techniques.
