3D Display Viewing Zone Remapping for Resolution and Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices struggle to balance image resolution and viewing angle, particularly in three-dimensional (3D) image display, limiting the overall viewing experience.
Innovation Solution
Incorporating an eye tracking unit to capture binocular and rotational information of a viewer, and a controller to generate mapping data that adjusts the viewing angles of side viewing zones based on this information, allowing for increased resolution and viewing angle through remapping of viewpoint images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the viewing angle of the main viewing zone is increased, then the viewing angle improves, but the resolution decreases
Solution Approach 1:
The viewing area is divided into multiple zones (main viewing zone and side viewing zones) with different viewing angles. The main viewing zone maintains a narrower viewing angle for high resolution, while side viewing zones have wider viewing angles for broader coverage, resolving the contradiction by segmenting the viewing area into functional regions
Solution Approach 2:
Different regions of the display have different local properties: the main viewing zone has optimized resolution for the primary viewer position, while side viewing zones have adjusted viewing angles for secondary positions. This local differentiation allows each region to optimize for its specific function without compromising overall system performance
2Shape
If eye tracking and dynamic remapping are implemented, then the viewing angle and resolution are optimized, but the device complexity increases
Solution Approach 1:
Multiple mapping data sets are pre-calculated and stored for different viewer positions and rotation angles. The system selects and applies the appropriate pre-computed mapping data based on eye tracking information, avoiding the need for complex real-time calculations while achieving optimized viewing angles and resolution
Solution Approach 2:
Mapping data acts as an intermediary between the eye tracking unit and the display panel. The controller uses the mapping data to translate eye position information into appropriate image rendering parameters, simplifying the control logic while achieving precise viewing angle optimization

AI summary
A display device includes a display panel including pixels, a viewing area forming unit forming a main viewing zone and side viewing zones where viewpoint images displayed by the display panel are provided, and an eye tracking unit extracting binocular information of a viewer. The display device further includes a controller controlling viewing angles of the side viewing zones to be different from a viewing angle of the main viewing zone based on the binocular information.
