Flexible Display Hinge with Segmented Polarization Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices with bezel portions suffer from screen size perception issues and image discontinuity when connected, as bezel removal is challenging due to manufacturing limitations, leading to reduced visibility and product reliability.
Innovation Solution
A panorama display device design that hinges and couples flexible display panels with polarization units, using adhesive and coupling members to minimize bezel portions, and forms connecting members like optically clear adhesives or touch screen panels to reduce image loss and enhance visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If bezel portions are removed to increase screen size perception, then visibility and screen area are improved, but manufacturing complexity and reliability deteriorate due to challenging manufacturing limitations
Solution Approach 1:
The patent extracts the polarization unit from the main display panel structure, separating it into an independent component that can be positioned at the edge. This extraction allows the display area to extend to the very edge of the panel without requiring a traditional bezel, while the polarization unit handles the functional requirements at the edge region
Solution Approach 2:
The patent transitions from a conventional planar display structure with bezel boundaries to an edge-extended display structure where the display area reaches the panel edge. The polarization unit is positioned in the edge region perpendicular to the main display area, creating a new spatial arrangement that eliminates the need for traditional bezel portions
2Area of stationary object
If multiple display devices are connected to form panorama display, then display area is expanded, but image discontinuity and visibility issues worsen due to bezel portions interfering with seamless connection
Solution Approach 1:
By extracting the polarization unit from the main display area and positioning it at the edge, the patent eliminates the bezel portions that would otherwise interfere with the connection between multiple display devices. This allows adjacent displays to be positioned closer together without the visual interruption of bezel boundaries
Solution Approach 2:
The patent merges the polarization unit with the edge region of the display panel, creating an integrated structure where the polarization function is combined with the boundary region. This merging allows multiple displays to be connected with their edge regions aligned, achieving seamless image continuity across the panorama display
3Adaptability or versatility
If polarization units are separated at hinged portions to enable flexibility, then adaptability and flexibility are improved, but structural complexity increases due to separated parts requiring additional coupling
Solution Approach 1:
The patent segments the polarization unit into separate parts that can be independently positioned and coupled. The polarization unit is divided such that one part is attached to the first display panel and another part is attached to the second display panel, with the separation occurring at the hinged portion where flexibility is required
Solution Approach 2:
The patent introduces a coupling member as an intermediary element that connects the separated polarization unit parts. This coupling member serves as a mediator that maintains the optical function while allowing the structural flexibility needed for hinged portions, simplifying the overall structure compared to rigid alternatives
