Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices lack efficient methods to seamlessly switch between two-dimensional (2D) and three-dimensional (3D) display operations, limiting user experience in viewing natural 3D images without special glasses.
Innovation Solution
An electronic device equipped with a display panel, an optical element, and a controller that senses the position of the optical element, measures displacement, and generates rendering parameters to switch between 2D and 3D display operations using a parallel rendering technique, allowing the device to produce 3D images by refracting light with a microlens array, microprism array, or lenticular lens array.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the device uses a fixed optical element configuration for 3D display, then 3D image quality is maintained, but the device cannot switch between 2D and 3D display modes
Solution Approach 1:
The optical element's position is made dynamic rather than fixed. The controller adjusts the optical element's position relative to the display panel based on the desired display mode (2D or 3D), enabling the system to adapt between different display configurations while maintaining optimal 3D image quality when in 3D mode
Solution Approach 2:
The system changes the positional parameter of the optical element to switch between display modes. By adjusting the distance and alignment between the optical element and display panel, the device can transition from 2D to 3D display mode while maintaining reliable 3D image quality when the parameter is set to the optimal position
2Productivity
If the device uses traditional 3D image generation methods, then image quality is acceptable, but the generation speed is slow and cannot meet real-time requirements
Solution Approach 1:
The patent replaces traditional mechanical or sequential image processing methods with a parallel rendering technique. The rendering parameter is calculated based on the optical element's position, enabling simultaneous generation of multiple view images through parallel computation, which significantly accelerates 3D image data generation while maintaining image quality
Solution Approach 2:
The system pre-calculates rendering parameters based on the optical element's position before actual 3D image generation is needed. This preliminary preparation of rendering parameters enables faster real-time 3D image generation by having the computational framework ready in advance
3Reliability
If the optical element is always positioned for optimal 3D display, then 3D image quality is maximized, but 2D display mode cannot be achieved
Solution Approach 1:
The optical element's position is made adjustable between two states: one optimized for 3D display and another for 2D display. This dynamic positioning capability allows the system to maintain maximum 3D image quality when needed while also enabling 2D display mode by repositioning the optical element
Solution Approach 2:
The optical element is designed to serve multiple functions by being repositionable. It can function as an optical element for 3D display when positioned at the optimal distance, and be detached or repositioned to allow 2D display mode, making the device universal in its display capabilities
