Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices that display images and video often suffer from non-uniform illumination, leading to a poor user experience due to inadequate light distribution.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light-emitting elements are used to illuminate the display panel, then the display can show images and video, but non-uniform illumination occurs leading to poor user experience
Solution Approach 1:
The reflector is segmented into multiple light-absorbing elements arranged in specific patterns on the backplane. Each light-absorbing element acts as an independent unit to absorb light in specific beam angles, allowing precise control over light distribution and achieving uniform illumination across the display panel.
Solution Approach 2:
Different regions of the backplane are assigned different functions: light-emitting elements are placed in certain areas while light-absorbing elements are strategically positioned in other areas. This local differentiation allows the system to optimize light emission in some regions while controlling light reflection and absorption in others, achieving overall illumination uniformity.
2Illumination intensity
If light-absorbing elements are added to the reflector, then illumination uniformity is improved, but the device structure becomes more complex
Solution Approach 1:
The light-absorbing elements are merged with the reflector structure, forming an integrated component. The reflector and light-absorbing elements work together as a unified system, where the reflector provides the structural framework and the light-absorbing elements are incorporated into its surface, reducing the need for separate components and simplifying the overall device structure.
Solution Approach 2:
The reflector serves multiple functions: it provides structural support, reflects light in desired directions, and incorporates light-absorbing elements to control specific beam angles. This multi-functionality reduces the need for additional separate components, maintaining device simplicity while achieving improved illumination uniformity.
