3D Display Moiré Suppression Layer for Lenticular Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D display technologies suffer from severe moiré issues, which degrade the display effect by causing interference between sub-pixel sizes and lenticular lenses, leading to a less realistic visual experience.
Innovation Solution
Incorporating a moiré suppression layer at the light-emitting side of the display panel, which includes a light scattering film and a haze layer, positioned between the polarizer and the lens structure or within the polarizer, to scatter light asymmetrically and reduce regular reflection, thereby alleviating moiré effects and enhancing display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lenticular lens structure is used for 3D display, then the three-dimensional visual effect is improved, but severe moiré interference occurs between the sub-pixels and lenses
Solution Approach 1:
A moiré suppression layer is introduced as an intermediary component between the display panel and the lenticular lens structure. This layer contains light scattering particles that randomize the phase of light waves, thereby suppressing the moiré interference patterns that would otherwise form due to the periodic interaction between sub-pixels and lenses.
Solution Approach 2:
The optical properties of the light emission are modified by introducing a haze layer with specific optical characteristics. The layer has a haze value within a predetermined range (e.g., 10-90%) and contains dispersion particles with specific size distributions, which changes the light scattering parameters to reduce moiré while preserving 3D display functionality.
2Object-affected harmful factors
If the moiré suppression layer is added to reduce moiré interference, then the display quality is improved, but the device structure becomes more complex
Solution Approach 1:
The moiré suppression layer is integrated with existing display components such as the polarizer or encapsulation layers. By combining the moiré suppression function with structures that are already present in the display device, the overall structural complexity is minimized while still achieving the desired moiré reduction effect.
Solution Approach 2:
The moiré suppression layer serves multiple functions simultaneously: it suppresses moiré interference, maintains light transmission for 3D display, and can be integrated with the polarizer structure. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity.
