Naked-eye Stereoscopic Display Crosstalk Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current naked-eye stereoscopic display systems suffer from image crosstalk, resulting in inadequate image detail, which is a limitation for applications requiring high image quality such as telesurgery.
Innovation Solution
A naked-eye stereoscopic display system with a controller that adjusts the light intensity of image beams emitted by sub-display regions, where the first sub-display regions have lower light intensity than the second sub-display region, utilizing a microlens array or parallax barrier to reduce crosstalk between display regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If uniform light intensity is used across all display regions, then the display system is simple to control, but image crosstalk occurs between display regions reducing image quality
Solution Approach 1:
The patent applies local quality by differentiating light intensity control across different display regions. Specifically, the first sub-display regions (edge regions) are controlled to emit image beams with lower light intensity than the second sub-display region (central region). This localized differentiation reduces crosstalk at the edges while maintaining central image quality, resolving the contradiction between image quality and control complexity.
Solution Approach 2:
The patent segments each display region into multiple sub-display regions (first sub-display regions and second sub-display region) with different light intensity characteristics. This segmentation allows independent control of light intensity for different functional zones, enabling crosstalk reduction at edges while preserving central display performance.
2Object-affected harmful factors
If the light intensity of edge display regions is reduced, then crosstalk between display regions is reduced, but the overall brightness of the display may be affected
Solution Approach 1:
The patent maintains different light intensity levels for different regions: the second sub-display region (central) maintains higher light intensity for brightness, while the first sub-display regions (edge) use lower light intensity to reduce crosstalk. This local differentiation allows the system to optimize for both crosstalk reduction and overall brightness without compromise.

AI summary
A naked-eye stereoscopic display system including a display, an optical element, and a controller is provided. The display is adapted to emit a plurality of image beams, and includes a plurality of display regions. Each of the display regions includes a plurality of first sub-display regions and a second sub-display region. A light configuration is performed on the image beams by the optical element, and then the image beams are projected out of the naked-eye stereoscopic display. The controller is electrically connected with the display. The controller controls the display, so that a light intensity of an image beam generated by the first sub-display regions is lower than a light intensity of an image beam generated by the second sub-display region. A display method of the naked-eye stereoscopic display is also provided.
