Organic EL Luminescent Device Depth Perception via Stacked Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing organic EL light emitting elements lack depth in their light emitting surface, resulting in a lack of sense of depth when viewed perpendicularly.
Innovation Solution
The solution involves an organic EL luminescent device comprising multiple organic EL panels with transparent electrodes and light emitting layers, where the panels are supported in an overlapping manner to create a sense of depth through parallax and varying luminescent colors, with optional reflecting members to enhance light emission and depth perception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single organic EL panel is used, then the device structure is simple, but the light emitting surface lacks depth and sense of depth
Solution Approach 1:
The patent applies dimensionality change by stacking multiple organic EL panels in the depth direction (perpendicular to the light emitting surface). This transforms a single-plane light emitting surface into a multi-layered three-dimensional structure, creating sense of depth while maintaining structural simplicity through standardized panel stacking
2Shape
If multiple organic EL panels are stacked to create depth, then sense of depth is improved, but device complexity increases
Solution Approach 1:
The patent segments the light emitting surface into multiple independent organic EL panels, each capable of emitting light. These segmented panels are stacked in the depth direction to create three-dimensional light emitting surfaces with sense of depth, while each panel remains a simple independent unit
3Illumination intensity
If transparent electrodes are used in all panels, then light transmission is improved, but luminance control becomes more complex
Solution Approach 1:
The patent applies local quality by differentiating electrode transparency across different panels. The panel closest to the light source uses a transparent electrode for maximum light transmission, while deeper panels use semi-transparent or opaque electrodes to control luminance distribution, creating natural depth perception without complex control systems
