3D Display Element Optical Arrangement for Color Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autostereoscopic 3D display elements often result in a distorted representation of colors and brightness due to the unintentional variation of light from different regions of a triplet along a spatial angle, leading to an incorrect perception of color and brightness values when viewed from different angles.
Innovation Solution
The use of an optical arrangement subordinate to the light-emitting component in the beam direction, which diverges and mixes light from adjacent triplets, ensuring that the color and brightness values of a triplet are perceived as mixed light without variation along a spatial angle, utilizing a combination of refractive and diffractive optical elements to achieve this effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If light from different regions of a triplet is allowed to pass through the optical arrangement separately, then the 3D display can achieve different brightness and color values along spatial angles, but the color and brightness representation becomes distorted and incorrect
Solution Approach 1:
The patent applies the merging principle by combining light from different regions of a triplet into a single mixed light beam that passes through a common optical element. Instead of allowing separate light paths from red, green, and blue regions to maintain their individual spatial angle characteristics, the optical arrangement merges these light sources so that their combined output is perceived as a single pixel with consistent color and brightness across viewing angles, thereby resolving the distortion problem while preserving 3D display functionality
2Ease of operation
If an optical arrangement is used to diverge light from adjacent triplets, then the 3D image impression is enhanced, but the light paths become complex and difficult to control
Solution Approach 1:
The patent employs an intermediary optical element (such as a lens or diffractive optical element) that acts as a mediator between the light-emitting regions and the observer's eye. This intermediary component simplifies the light path management by providing a standardized optical function that simultaneously achieves triplet divergence for 3D imaging and maintains controlled light trajectories, thereby enhancing 3D image quality without excessive complexity in light path design
