Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Light-emitting organic components with non-planar exit surfaces suffer from efficiency losses due to self-illumination and chromatic aberrations, as light is absorbed or only partly reflected, leading to reduced light quality and efficiency.
Innovation Solution
Incorporating optical structures at the non-planar light exit surface, such as prisms, lenses, and light-scattering elements, which redirect and diffuse light to minimize self-illumination and correct color aberrations, thereby enhancing light distribution and quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a non-planar light exit surface is used, then light distribution is improved, but self-illumination occurs causing efficiency losses
Solution Approach 1:
The light exit surface is divided into multiple planar partial surfaces arranged at different orientations. Each partial surface emits light in a specific direction, preventing light from reflecting back onto other emitting surfaces. This segmentation eliminates self-illumination while maintaining improved light distribution across the display surface.
2Illumination intensity
If a non-planar light exit surface is used, then light distribution is improved, but chromatic aberrations occur reducing light quality
Solution Approach 1:
The display is divided into multiple independent light-emitting regions, each with its own planar surface oriented at a specific angle. This allows each region to emit light with consistent color characteristics without the chromatic aberrations that would occur on a continuously curved non-planar surface, thereby maintaining high light quality.
3Ease of manufacture
If planar light exit surfaces are used, then manufacturing is simplified, but light distribution is limited
Solution Approach 1:
Instead of using a single planar surface for all light emission, the invention employs multiple planar surfaces oriented at different angles relative to the display surface normal. This asymmetric arrangement of planar surfaces enables light to be distributed in multiple directions, significantly improving overall light distribution while maintaining the manufacturing advantages of planar surfaces.
