Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current naked-eye 3D display technologies face limitations in viewing range, resolution, and comfort, with severe crosstalk and conflict between focus and convergence, restricting the application of light field and super multi-view displays, especially in medium-and-large-sized devices.
Innovation Solution
A display device with a light splitting system using arrayed lenses and sub-pixel subdivision units that alternate between left and right eye views, allowing for adjustable focus and reduced crosstalk, enabling seamless switching between light field and super multi-view displays by determining the viewer's eye position using an eye tracker and adjusting pixel island displays accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If light field display mode is used in central region, then viewing comfort and focus adjustment are improved, but device complexity increases
Solution Approach 1:
The display panel is divided into multiple pixel islands, with the central region pixel islands configured for light field display mode and edge region pixel islands configured for super multi-view display mode. This segmentation allows different viewing modes to coexist, improving comfort in the central region without requiring the entire device to be complex light field technology.
Solution Approach 2:
The system dynamically switches between light field display mode and super multi-view display mode based on the detected eye position. When eyes are in the central region, light field mode is activated for better comfort; when eyes move to edge regions, super multi-view mode is activated. This dynamic adaptation optimizes viewing comfort without permanently increasing device complexity.
2Area of moving object
If super multi-view display mode is used in edge region, then viewing range is improved, but resolution decreases
Solution Approach 1:
Different display modes are applied to different spatial regions: light field mode with higher effective resolution is used in the central region where viewers typically focus, while super multi-view mode with broader viewing range is used in edge regions. This local quality differentiation ensures that resolution requirements are met in the critical central region while expanding viewing range in peripheral regions.
3Illumination intensity
If naked-eye 3D display is implemented, then visual impact is improved, but crosstalk increases
Solution Approach 1:
The display is segmented into different viewing zones with different optical characteristics. The light splitting device with microlenses is positioned to create distinct viewing regions, where each eye receives primarily its intended view. This segmentation reduces crosstalk by spatially separating the optical paths for left and right eye views while maintaining the naked-eye 3D effect.

Implementation Method 1
a light splitting device on a side of a display surface of the display panel, and including a plurality of lenses arranged in an array, where one pixel island corresponds to one lens, a main lobe angle of each of the lenses satisfies that monocular view images displayed by the sub-pixel subdivision units in one pixel island are projected onto a corresponding independent visible region by means of different lenses
