Solution Overview
Problem
Existing flexible organic light emitting devices (OLEDs) face challenges in dynamically controlling the distribution of radiant intensity, as their shape and curvature are fixed, limiting their ability to adapt to varying illumination needs.
Innovation Solution
A light source comprising a support structure with movable portions and flexible substrates that change shape, allowing the OLEDs to adjust their curvature and distribution of radiant intensity by attaching to multiple support structures via elastic connections or external mechanisms, enabling dynamic control of illumination patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the OLED uses a fixed flexible substrate, then the device structure is simple, but the distribution of radiant intensity cannot be dynamically controlled
Solution Approach 1:
The patent applies the dynamics principle by making the flexible substrate movable relative to the support structure, allowing it to change its shape and curvature dynamically. This enables the OLED to adjust its radiant intensity distribution by moving between different curved states, transforming a static device into a dynamic one that can adapt to varying illumination requirements.
Solution Approach 2:
The patent segments the device into distinct components: a support structure with multiple support members and a flexible substrate that can move independently among them. This segmentation allows the flexible substrate to be manipulated separately to change its curvature and orientation, enabling dynamic control of light distribution while keeping the overall device structure manageable.
2Adaptability or versatility
If the OLED shape is fixed, then manufacturing is easier, but the ability to adapt to varying illumination needs is limited
Solution Approach 1:
The patent implements dynamics by enabling the flexible substrate to transition between different shapes after manufacturing. The substrate is designed to be movable among support members, allowing it to assume various curvatures and orientations during operation. This dynamic capability provides adaptability to different illumination needs without complicating the manufacturing process, as the physical structure remains relatively simple.
3Stability of the object's composition
If the support structure is rigid, then structural stability is high, but the curvature and shape of the OLED cannot be adjusted
Solution Approach 1:
The patent segments the support system into multiple discrete support members that provide structural stability while allowing the flexible substrate to move among them. This segmented approach maintains overall structural integrity through the support framework while enabling local flexibility and curvature adjustment of the substrate, resolving the contradiction between rigidity and shape adaptability.
Solution Approach 2:
The patent employs a flexible substrate that can be manipulated to change its curvature while being supported by a stable support structure. The flexible substrate acts as a thin film that can assume different shapes when positioned among the support members, allowing curvature adjustment without compromising the structural stability provided by the rigid support framework.

AI summary
Flexible substrates bearing OLEDs are provided. The flexible substrates are attached to support structures that, when moved, cause the flexible structures to change shape and to thereby change the distribution of radiant intensity emanating from the OLEDs on the flexible substrates.
