OLED Display Device Dynamic Sub-Section Folding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional OLED display devices cannot satisfy large-size folding requirements due to limitations in expandable size and folding methods.
Innovation Solution
The OLED display device incorporates multiple sub-display sections dynamically connected through bending, curling, and stretching mechanisms, including a curling mechanism with a sliding rail and pulleys, allowing for expansion into a large-area display region or accommodation into a single section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If conventional OLED display devices use single folding methods, then the structure is simple, but the expandable size is limited and cannot satisfy large-size folding requirements
Solution Approach 1:
The display screen is divided into multiple sub-display sections (first, second, and third sub-display sections) that can be independently folded and positioned. Each sub-display section can be dynamically connected to form different configurations, enabling large-size folding while maintaining manageable complexity through modular segmentation.
Solution Approach 2:
The patent implements dynamic connection between sub-display sections through bending sections that can change their state between folded and unfolded positions. The bending sections allow the sub-display sections to be dynamically reconfigured, transitioning between a compact folded state and an expanded display state, thereby achieving variable expandable size.
2Volume of moving object
If the OLED display module is completely folded, then the display screen is compact, but the sub-display sections cannot be fully integrated into a single section
Solution Approach 1:
The third sub-display section is designed to be accommodated into the second sub-display section when folded, creating a nested configuration. The bending section enables the third sub-display section to be positioned within or adjacent to the second sub-display section, achieving compact folded volume while maintaining the ability to integrate multiple display sections into a unified structure.
3Adaptability or versatility
If multiple sub-display sections are dynamically connected, then large-size folding is enabled, but the mechanism complexity increases
Solution Approach 1:
The bending section serves multiple functions: it connects sub-display sections, enables folding movement, and allows dynamic reconfiguration between different display states. By making the connection mechanism multi-functional, the patent reduces overall system complexity while maintaining high adaptability for various folding configurations.
