Switchable Retarder 3D Glasses for Seamless Mode Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D display technologies require viewers to wear specific glasses for 3D mode and cannot easily switch between 3D and 2D modes, limiting their functionality and popularization.
Innovation Solution
A display system that uses two types of lenses (first and second lenses) with different circular polarization properties to allow viewers to see either parallax images for 3D mode or different images for 2D mode, and includes a switchable retarder to alternate between modes, enabling multi-view display by synchronizing lens operation with image refresh frequency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 3D glasses are designed to function only with 3D display mode, then the 3D viewing experience is optimized, but the adaptability and versatility of the glasses are limited
Solution Approach 1:
The patent applies universality by designing 3D glasses that can function in multiple display modes (3D, 2D, and multi-view) through a switchable retarder mechanism. The glasses include a retarder that can be switched between different retardation states to enable compatibility with various display modes, allowing a single pair of glasses to serve multiple purposes rather than being limited to 3D mode only.
2Adaptability or versatility
If the display system uses switchable retarder to alternate between 3D and 2D modes, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent merges the 3D and 2D display functionalities into a single optical system by combining the retarder with the existing polarizing lenses. The switchable retarder is integrated into the glasses structure, allowing it to work in conjunction with the polarizing lenses to achieve both 3D and 2D modes without requiring separate optical paths or multiple complete lens systems.
3Adaptability or versatility
If the display apparatus displays images alternately with different circular polarization, then the multi-view capability is improved, but the speed of mode switching must be synchronized precisely
Solution Approach 1:
The patent employs periodic action by displaying images alternately with different circular polarizations at a frequency synchronized with the refresh rate of the display apparatus. The switchable retarder in the glasses switches between different retardation states in synchronization with the alternating display of left-eye and right-eye images, enabling the viewer to see different images through different lenses while maintaining proper temporal synchronization.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables seamless switching between 3D, 2D, and multi-view display modes, allowing viewers to see different images or multiple 2D images irrelevant to each other, enhancing user experience and facilitating the popularization of 3D display technology.
Implementation Method 1
a levorotary circular polarized light is provided by the first display regions, a dextrorotary circular polarized light is provided by the second display regions
Implementation Method 2
each of the first lenses permits the levorotary circular polarized light passing through and cuts the dextrorotary circular polarized light, and each of the second lenses permits the dextrorotary circular polarized light passing through and cuts the levorotary circular polarized light

AI summary
A display system including a display apparatus for displaying a first image and a second image, two first lenses and two second lenses is provided. When a viewer sees the display apparatus via one first lenses and one second lenses, and the first image as well as the second image are parallax images, the first and second images are respectively saw by different eyes of the viewer. When the viewer sees the display apparatus through the two first lenses, and the first image as well as the second image are not parallax images, the first image irrelevant to the second image is saw by the viewer. When the viewer sees the display apparatus through the two second lenses, and the first image as well as the second image are not parallax images, the second image irrelevant to the first image is saw by the viewer.
