Solution Overview
Problem
Existing three-dimensional display devices rely on stereoscopic illusions and require headwear or limited viewing areas, failing to provide a real 3D effect for multiple users and often causing discomfort due to mis-calibration issues.
Innovation Solution
A display device with movable pixels and actuators, allowing for real 3D image rendering by varying pixel depth based on received position and luminance values, enabling multiple users to view a 3D image that changes with viewing angle without the need for headwear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stereoscopic display methods (polarized glasses, anaglyph glasses) are used to create 3D images, then the illusion of depth is achieved, but the viewing experience is limited by requiring headwear or having restricted viewing areas
Solution Approach 1:
The patent transitions from 2D display planes to 3D spatial arrangement by moving pixels normal to the display plane. This creates genuine three-dimensional image structures that can be viewed from multiple angles without requiring stereoscopic glasses or headwear, fundamentally changing the viewing dimension and eliminating the need for restrictive viewing conditions
Solution Approach 2:
The patent implements dynamically controllable pixel positions through actuators that can move pixels to different depths based on received position values. This dynamic positioning capability allows the system to render 3D images with varying depth configurations, enabling multiple users to simultaneously view authentic 3D effects from different viewing angles without the limitations of static stereoscopic methods
2Reliability
If limited viewing area devices are used to generate 3D images, then the 3D effect is viewable within a restricted zone, but it becomes difficult or impossible to provide satisfactory 3D effects for multiple users simultaneously
Solution Approach 1:
By arranging pixels in three-dimensional space rather than confined to a 2D plane, the patent creates volumetric 3D images that naturally accommodate multiple viewing angles and positions. This spatial expansion allows multiple users to simultaneously experience authentic 3D effects from different locations without the restrictive viewing cones inherent in traditional 3D display devices
Solution Approach 2:
The patent creates a universal 3D display system that serves multiple users simultaneously from various positions. The movable pixel architecture and angle-independent rendering capability make the device adaptable to different viewing configurations, enabling it to function effectively for single or multiple users without requiring separate viewing zones or devices
3Reliability
If stereoscopic illusion methods are used to create depth perception, then 3D images can be generated, but mis-calibration issues cause viewer discomfort
Solution Approach 1:
The patent creates authentic physical 3D copies of objects by positioning actual pixels at their true spatial coordinates in three-dimensional space. Rather than creating optical illusions that approximate depth, the system directly reproduces the physical geometry of 3D objects, eliminating calibration errors and the resulting viewer discomfort associated with stereoscopic methods
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a genuine 3D effect for multiple users simultaneously, improving image quality and reducing discomfort by rendering depth variations that mimic real 3D objects, enhancing the viewing experience.
