Spatial Segmentation for Bright Naked-Eye 3D Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional time-division multiplexing methods in display technologies result in inadequate screen brightness and a limited number of images that can be generated, making it difficult to effectively secure content from unauthorized viewers, especially with modern high-brightness and high-resolution displays.
Innovation Solution
A display method that processes multiple images to form base compositions, which are arranged spatially to create a composite image viewable to the naked eye, while a subset of these images can be selectively viewed as a modulated image using an optical modulation device, allowing for improved brightness and secure content display by adjusting luminance in specific regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If time-division multiplexing methods are used to display multiple images, then information security is improved, but screen brightness becomes inadequate
Solution Approach 1:
The display screen is segmented into multiple independent display regions (first display region and second display region) that can simultaneously display different images. This spatial segmentation allows multiple images to be displayed at the same time without requiring time-division multiplexing, thereby maintaining screen brightness while achieving information security through spatial separation of content.
Solution Approach 2:
The patent transitions from time-division multiplexing (temporal dimension) to spatial division (spatial dimension) by creating multiple independent display regions on the screen. This dimensional change allows simultaneous display of multiple images in different spatial locations, resolving the contradiction between security (requiring multiple images) and brightness (reduced by temporal multiplexing).
2Reliability
If time-division multiplexing methods are used to display multiple images, then content protection is improved, but the number of images that can be generated is limited
Solution Approach 1:
The screen is divided into multiple independent display regions that can simultaneously present different images. This segmentation enables the system to generate and display multiple images at the same time rather than sequentially, increasing the quantity of images from limited temporal multiplexing to multiple concurrent spatial displays, thereby enhancing content protection.
Solution Approach 2:
Multiple independent display regions are merged into a single screen interface, allowing simultaneous presentation of multiple images. This combination of spatial regions enables the system to generate and protect more images by displaying them concurrently in different regions rather than limiting to a few images through time-division methods.
3Illumination intensity
If spatial arrangement of base compositions is used to create composite image, then picture brightness is enhanced, but device complexity increases
Solution Approach 1:
The processing system segments the display task into independent display regions with specific luminance requirements. Each region processes images independently with dedicated luminance control, simplifying the overall processing complexity while maintaining high brightness in each region. The segmentation allows parallel processing rather than complex sequential operations.
Solution Approach 2:
Different display regions are assigned different luminance characteristics (first luminance for first region, second luminance for second region) according to local requirements. This local quality approach allows each region to be optimized independently for brightness without requiring complex global processing, thereby enhancing overall picture brightness while managing device complexity through localized control.

AI summary
A display method includes: processing a plurality of images to form base compositions; and presenting the base compositions with different images in a spatial arrangement which as a whole form a composite image viewable to a naked-eye viewer; wherein a subset of the plurality of images are selectively viewable as a modulated view to a user with an optical modulation device.
