Dual Light-Absorbing Layer Display Layout for Reflection Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with light-emitting elements face challenges in improving image quality due to light reflection issues, which affect both internal and external light, leading to decreased contrast and reliability.
Innovation Solution
A display device configuration that includes a first light-absorbing layer and a second light-absorbing layer, where the second light-absorbing layer faces the first light-absorbing layer with the light-emitting elements in between, effectively suppressing light reflection on both sides and maintaining the insulating properties of the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single light-absorbing layer is provided to suppress light reflection, then light reflection is suppressed on one side, but light reflection remains on the other side, resulting in insufficient image quality improvement
Solution Approach 1:
The light-absorbing function is segmented into two separate layers positioned on opposite sides of the light-emitting elements. The first light-absorbing layer is provided on the upper side, and the second light-absorbing layer is provided on the lower side, allowing each layer to independently suppress light reflection from its respective side, thereby comprehensively improving image quality
Solution Approach 2:
The solution transitions from a single-layer configuration to a dual-layer configuration across different spatial dimensions (upper and lower sides). By adding the second light-absorbing layer on the lower side facing the first light-absorbing layer with the light-emitting elements therebetween, the system addresses light reflection from both upper and lower directions, effectively eliminating the harmful effect from multiple dimensions
2Reliability
If light-absorbing layers are added to suppress reflection, then image quality improves, but device structure becomes more complex
Solution Approach 1:
The light-absorbing function is divided into two separate layers positioned on opposite sides of the light-emitting elements. The first light-absorbing layer is provided on the upper side, and the second light-absorbing layer is provided on the lower side, allowing each layer to independently suppress light reflection from its respective side, thereby comprehensively improving image quality
Solution Approach 2:
Both the first and second light-absorbing layers serve the same function of suppressing light reflection, but they are positioned on opposite sides to address different reflection paths. This multi-functional arrangement allows a single configuration to simultaneously handle upper and lower side reflections, improving image quality without requiring entirely separate systems for each side

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration significantly improves image quality by reducing light reflection and maintaining the reliability of the display device by effectively absorbing both internal and external light, thereby enhancing contrast and preventing insulating layer deterioration.
Implementation Method 1
a first light-absorbing layer having an opening at a position that faces the light-emitting elements
Implementation Method 2
