Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional auto-stereoscopic display technologies, such as holography and volumetric, face limitations in real-time performance, resolution, and wide application due to size constraints, while stereoscopic methods cause user discomfort by creating a false three-dimensional effect, leading to limited adoption.
Innovation Solution
An auto-stereoscopic display apparatus with a display panel and a lens layer featuring lenticular lenses, where each lenticular lens covers multiple sub-pixels, and application software calculates optimal parameters like sub-pixel width, lenticular lens angle difference, and viewing distance to enhance three-dimensional image quality and user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional stereoscopic display methods (color filter glasses, polarizing glasses, shutter glasses) are used, then three-dimensional images can be displayed, but user comfort deteriorates due to dizziness and vomiting caused by false three-dimensional effects
Solution Approach 1:
The patent replaces conventional stereoscopic methods that require mechanical glasses (color filter, polarizing, shutter glasses) with an auto-stereoscopic display that uses optical principles (lenticular lenses or parallax barriers) to achieve three-dimensional effects without any wearable devices, thereby eliminating user discomfort associated with false depth perception
Solution Approach 2:
The patent changes the fundamental parameter of depth perception from false stereoscopic depth (created by binocular disparity through glasses) to real optical depth (created by light field manipulation through lenticular lenses or parallax barriers), transforming the three-dimensional display mechanism to eliminate harmful effects
2Reliability
If holography auto-stereoscopic display technology is used, then real three-dimensional images can be displayed, but device complexity and size increase due to crystal size requirements of acousto-optic modulators
Solution Approach 1:
The patent extracts and removes the complex acousto-optic modulator crystal component from the holography system, replacing it with simpler optical elements (lenticular lenses or parallax barriers) that can achieve real three-dimensional effects without requiring large crystals, thereby reducing device complexity and size
Solution Approach 2:
The patent uses lenticular lenses or parallax barriers to create optical copies of the image that simulate real three-dimensional depth perception, replacing the need for complex holographic crystal structures while achieving similar visual effects
3Reliability
If volumetric auto-stereoscopic display technology is used, then real three-dimensional images can be displayed, but resolution decreases due to reflector size limitations
Solution Approach 1:
The patent introduces lenticular lenses or parallax barriers as intermediary optical elements between the display panel and the viewer, which manipulate light to create real three-dimensional depth perception without requiring large reflector structures, thereby maintaining high image resolution
4Ease of operation
If lenticular lenses or parallax barriers are used in spatial-multiplexed display, then three-dimensional images can be displayed without glasses, but the three-dimensional effect is fake and causes user discomfort
Solution Approach 1:
The patent enhances the static lenticular lens or parallax barrier system with dynamic control of light field distribution, enabling the system to adaptively adjust the optical path and depth perception characteristics in real-time, thereby creating authentic three-dimensional effects that respond to viewer position and movement
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 more effective and user-friendly three-dimensional display by optimizing the arrangement of lenticular lenses and sub-pixels, improving image quality and reducing user discomfort, making it suitable for wider applications.
Implementation Method 1
lenticular lenses or parallax barriers for light splitting are employed in the spatial-multiplexed display apparatus so that the odd-pixel and the even-pixel image pairs are able to be projected to the left eye (or the right eye) and the right eye (or the left eye), respectively
