Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses providing three-dimensional images often require glasses, which is inconvenient, and glasses-free systems face challenges with reduced resolution and stereoscopic effects.
Innovation Solution
An electronic apparatus utilizing a first display panel for multi-view images and a second display panel for two-dimensional images, with a micro-lens array and a processor to generate and control multi-view and two-dimensional images based on object information, enabling glasses-free 3D viewing with improved resolution and stereoscopic effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a glasses system is used to provide three-dimensional images, then satisfactory stereoscopic sense is achieved, but the viewer must use glasses which is inconvenient
Solution Approach 1:
The display system is segmented into multiple independent display regions (first display region and second display region) that can be controlled separately. The first display region shows the multi-view image for 3D effect while the second display region shows the two-dimensional image, allowing the system to provide both stereoscopic viewing and conventional viewing experiences simultaneously without requiring glasses
Solution Approach 2:
A transparent display panel is introduced as an intermediary component between the multi-view image display and the viewer. This transparent panel allows light from the multi-view image to pass through while displaying the two-dimensional image, enabling glasses-free 3D viewing by mediating between the 3D content and the viewer's eyes
2Ease of operation
If a glasses-free system is used to view three-dimensional images, then viewing without glasses is possible, but resolution is reduced
Solution Approach 1:
The display area is segmented into two separate regions: the first display region dedicated to multi-view images with higher pixel density for 3D content, and the second display region for two-dimensional images. This segmentation allows each region to be optimized for its specific purpose, maintaining high resolution in the 3D viewing area while enabling glasses-free operation
Solution Approach 2:
Different display regions are assigned different quality characteristics - the first display region uses a higher pixel density suitable for multi-view 3D images, while the second display region can use lower pixel density for 2D content. This local differentiation of quality allows the system to maintain high resolution where needed (in the 3D region) while reducing overall system complexity
3Reliability
If a multi-view image is displayed to provide three-dimensional effect, then stereoscopic viewing is enabled, but the image quality and resolution are compromised
Solution Approach 1:
The display system segments the image content into two separate displays: the first display panel shows the multi-view image with stereoscopic information for 3D effect, while the second transparent display panel shows the corresponding two-dimensional image. This segmentation allows the multi-view image to be optimized for stereoscopic effect without compromising overall image quality, as the 2D reference image is displayed separately with full resolution
Solution Approach 2:
The transparent display panel acts as an intermediary that overlays the two-dimensional image on top of the multi-view image display. This intermediary layer provides a high-quality 2D reference that compensates for any resolution compromises in the multi-view display, allowing viewers to see both the 3D effect and maintain access to high-quality 2D image information
