Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stereoscopic displays for naked eyes using linearly polarized light cause visual fatigue and visual disturbances due to their reliance on polarized light control technology, which is not akin to natural light perception.
Innovation Solution
Incorporating a light converting module between the two-dimensional display panel and the stereoscopic module, which converts linearly polarized light into circularly polarized light, simulating natural light and alleviating visual fatigue by using a quarter-wave plate, half-wave plate, and a liquid crystal type circularly polarization controller to output three-dimensional images.

Engineering Contradiction Analysis
1Reliability
If linearly polarized light is used in stereoscopic display for naked eyes, then the stereoscopic display effect is achieved through binocular parallax, but visual fatigue and visual disturbances occur
Solution Approach 1:
The patent changes the polarization state parameter from linear polarization to circular polarization by introducing a quarter-wave plate. This parameter change transforms the light's polarization characteristics while maintaining the stereoscopic display effect, thereby reducing visual fatigue and disturbances caused by linearly polarized light
Solution Approach 2:
The quarter-wave plate serves as an intermediary optical element between the linearly polarized light source and the viewer's eyes. It mediates the transformation of light polarization state, converting linearly polarized light into circularly polarized light to eliminate harmful visual effects while preserving the stereoscopic effect
