3D Display Panel Assembly with Adjusting Panel for Glasses-Free Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D display technologies rely on special glasses, limiting their application range and user comfort, as they do not provide a glasses-free 3D viewing experience.
Innovation Solution
A 3D display panel assembly comprising a display panel with subpixels arranged in an array, where adjacent lines emit primary light and display black, and an adjusting panel with units that adjust light transmittance to direct light to the left and right eyes independently, allowing for 3D image formation without glasses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If special glasses are used for 3D display, then 3D viewing effect is achieved, but user comfort and application range are limited
Solution Approach 1:
The patent extracts and removes the glasses component from the 3D display system. By using a spatial light modulator and controlling light transmission paths directly, the invention achieves 3D display without requiring special glasses, thereby improving user comfort and expanding application range while maintaining the 3D viewing effect
Solution Approach 2:
The patent introduces a spatial light modulator as an intermediary component between the display and the viewer's eyes. This modulator controls the transmission and direction of light to different eyes independently, enabling glasses-free 3D display by mediating the light paths rather than requiring external glasses
2Reliability
If special glasses are used for 3D display, then 3D viewing effect is achieved, but application range is limited
Solution Approach 1:
By removing the glasses requirement, the invention expands the application range of 3D display technology to various scenarios such as mobile devices, public displays, and environments where glasses cannot be worn, while maintaining reliable 3D viewing effect through direct light control
Solution Approach 2:
The spatial light modulator design enables the display system to serve multiple functions and applications. The same hardware can adapt to different viewing conditions and device types (mobile phones, tablets, displays), making the 3D technology universally applicable without being restricted to specific glass-based systems
