Display Canopy Anti-Reflective Components Contrast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices with light emitting elements arranged in a matrix struggle to maintain good contrast while minimizing the effect of incoming light, particularly sunlight, and ensuring a good viewing angle from below, as existing solutions fail to adequately reduce reflection between canopies and increase contrast effectively.
Innovation Solution
A display device with light emitting elements arranged in a matrix, featuring canopies at the upper and lower ends and at least two types of anti-reflective components with different reflection angles, effectively blocking incoming light and reducing reflections, thereby ensuring a good viewing angle and increased contrast.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pixels and the auxiliary canopy are separated by a specific distance to ensure a good viewing angle from below the display device, then the viewing angle is improved, but the region between the pixels and the auxiliary canopy increases where incident light from the outside can be reflected in the display observation direction, leading to a decrease in contrast
Solution Approach 1:
The patent applies local quality by providing anti-reflective components at specific locations (between pixels and the auxiliary canopy) rather than uniformly across the entire display. These components are strategically positioned in the regions where incident light reflection occurs, allowing the viewing angle to be maintained while locally addressing the reflection problem to preserve contrast.
2Object-affected harmful factors
If conventional canopy structures are used to block incoming light from diagonally above the light emitting elements, then the contrast is improved, but the reflection of incoming light between the auxiliary canopy and the main canopy is not adequately reduced
Solution Approach 1:
The patent converts the harmful reflection between canopies into a beneficial effect by using anti-reflective components that redirect incident light away from the display observation direction. Instead of simply blocking light, these components manipulate the reflection angles to prevent reflected light from reaching observers, thereby reducing the harmful reflection effect while maintaining the canopy's light-blocking function.
3Device complexity
If anti-reflective components with single reflection angle are used, then the structure is simple, but reflections from multiple incident angles cannot be adequately suppressed
Solution Approach 1:
The patent segments the anti-reflective function into multiple components with different reflection angles. Rather than using a single anti-reflective component, the invention employs multiple components arranged to handle different incident light angles, thereby comprehensively suppressing reflections from various directions while maintaining reasonable structural complexity.

Function Achieved in This Case
The solution effectively blocks incoming light from above and minimizes reflections at the display face, ensuring a good viewing angle from below and significantly improving contrast, even in outdoor conditions.
Implementation Method 1
