Light-Absorbing Display Surface for Reflection and Contrast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face challenges in simultaneously suppressing light reflection on the surface and maintaining high contrast, leading to deteriorated video representation quality depending on the installation environment.
Innovation Solution
A display system incorporating a light absorption layer with openings for light emission, which absorbs external light and reduces surface reflections while allowing light from light sources to be emitted effectively, thereby achieving both suppression of light reflection and high contrast.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a glossy display surface is used, then high contrast is maintained, but light reflection on the surface increases
Solution Approach 1:
The display surface is segmented into multiple functional layers: a light absorption layer with light-absorbing particles, a semi-transparent layer, and a reflective layer. This segmentation allows each layer to perform its specific function - the absorption layer reduces reflections, the semi-transparent layer allows light transmission, and the reflective layer enhances contrast by reflecting light back through the display.
Solution Approach 2:
The display employs a composite structure combining multiple materials with different optical properties: light-absorbing particles (such as carbon black or Vantablack), semi-transparent materials, and reflective materials. This composite approach enables the surface to simultaneously achieve low reflectivity and high contrast by leveraging the complementary properties of each material.
2Object-affected harmful factors
If a matted display surface is used, then light reflection is suppressed, but contrast of display video is lowered
Solution Approach 1:
Instead of using a uniformly matted surface, the invention segments the surface into functional layers where the light absorption layer handles reflection suppression and the reflective layer handles contrast enhancement. This segmentation allows the system to overcome the limitation of matted surfaces that normally reduce contrast.
Solution Approach 2:
Different regions of the display surface have different optical properties at the microscopic level. The light absorption layer contains particles that selectively absorb light, while the reflective layer contains materials that reflect light. This local variation in optical quality enables the surface to simultaneously suppress reflections and maintain high contrast.
