Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passive displays, such as LCDs and EP displays, lack the ability to emit light, limiting their practical applications due to inherent low power consumption and limited use in many scenarios.
Innovation Solution
A multimode display system that switches between a two-dimensional (2D) mode and a multiview mode, utilizing a time-multiplexed approach to enhance display quality by segmenting multiview images into optimized views for 2D and multiview modes, with directional and broad-angle lighting, respectively, to achieve improved resolution and depth perception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If passive displays (LCDs, EP displays) are used to reduce power consumption, then energy efficiency is improved, but the ability to emit light is lost, limiting practical applications
Solution Approach 1:
The display system dynamically switches between passive display mode (for power saving) and active display mode (for enhanced functionality) based on operational requirements. The multimode display can operate in both 2D and multiview modes, adapting its light emission characteristics to match the desired outcome between energy efficiency and application versatility.
Solution Approach 2:
The display device changes its operational parameters by switching between different modes (2D mode and multiview mode) that have different light emission characteristics. In 2D mode, the display operates passively with low power consumption, while in multiview mode, it activates light emission capabilities to provide enhanced adaptability for various practical applications.
2Manufacturing precision
If multiview images are displayed in multiview mode to provide depth perception, then visual quality is improved, but resolution may be compromised compared to 2D mode
Solution Approach 1:
The multiview image is segmented into multiple view images, each optimized for specific viewing angles and depth perceptions. By dividing the composite multiview image into separate view components, the system can allocate display resources to maintain high resolution for each individual view while collectively providing enhanced visual quality and depth perception across multiple perspectives.
Solution Approach 2:
The display system uses time-multiplexed operation to periodically switch between displaying different view images in the multiview mode. This periodic switching allows the display to present multiple views sequentially at high resolution, creating the perception of simultaneous high-resolution multiview display while maintaining frame rate requirements.
3Measurement precision
If 2D mode is used to display high-resolution images, then resolution is improved, but depth perception and multiview properties are lost
Solution Approach 1:
The display device is designed with multi-functionality to operate in both 2D mode (providing high resolution) and multiview mode (providing depth perception). The same hardware platform can universally serve both purposes by switching between operational modes, allowing the system to deliver high resolution when needed while also providing enhanced visual characteristics with depth perception when multiview functionality is activated.
4Device complexity
If a single display mode is used to simplify the system, then device complexity is reduced, but adaptability to different viewing scenarios is limited
Solution Approach 1:
The display system employs dynamic mode switching capability that allows transition between 2D and multiview modes based on viewing requirements. This dynamic adaptability enables a single display device to handle multiple viewing scenarios without requiring separate dedicated displays for each mode, thereby maintaining relatively simple system structure while achieving high versatility.
Solution Approach 2:
The multimode display device provides universal functionality by integrating both 2D and multiview display capabilities in a single system. This multi-functional design allows the same hardware to adapt to different viewing scenarios (single-view high-resolution viewing vs. multi-view depth-perception viewing) without requiring multiple separate display systems, thus balancing complexity and versatility.

AI summary
Described herein are system and methods to improve the image quality of a multiview image. In some embodiments a zero disparity plane image is generated based on a view of a multiview by identifying portions of the multiview image that correspond to the zero disparity plane. The zero disparity plane image and view images of the multiview image may be transmitted to a time-multiplexed display. The time-multiplexed display may operate according to a two-dimensional (2D) mode and a multiview mode. The time-multiplexed display may be configured to display the zero disparity plane image and the view images as a composite image.
