Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Open office environments face distractions due to coworker activity, and existing visual display technologies, such as high-definition displays, are expensive, cumbersome, and fail to blend with surroundings, creating unrealistic visual changes that can be distracting.
Innovation Solution
A 3D display system using a directly-lit transmissive diffuser panel with an adjustable support member and LED array, allowing for dynamic, diffused images that can be modified in color and intensity, creating a three-dimensional effect without noticeable edits, and can be mounted to accommodate various viewing angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If high definition displays are used to display natural scenes, then visual quality is improved, but device cost and complexity increase
Solution Approach 1:
The patent uses a light field display system that captures and reproduces the optical properties of natural scenes through light field copying, rather than using expensive high-definition displays. The light field camera captures multi-viewpoint images and the light field display reconstructs the original light field, creating realistic visual experiences without requiring high-definition display hardware.
2Illumination intensity
If completely defined high definition visuals are used, then image clarity is improved, but adaptability to different viewing angles decreases
Solution Approach 1:
The patent segments the visual information into multiple light rays traveling in different directions, capturing views from multiple viewpoints around the scene. This segmentation of light field data allows the display to reconstruct images that maintain clarity across different viewing angles, as each viewpoint has its own captured light field information.
Solution Approach 2:
The patent transitions from traditional 2D display to 4D light field display by adding two spatial dimensions (horizontal and vertical viewing angles) to the conventional two image plane dimensions. This dimensional expansion enables the display to provide clear images from multiple viewing angles simultaneously, resolving the contradiction between image clarity and viewing angle adaptability.
3Ease of manufacture
If fixed visual displays are used, then manufacturing simplicity is improved, but dynamic adaptability decreases
Solution Approach 1:
The patent implements a dynamic light field display system where the captured light field scenes can be actively altered and modified in real-time. The system can transition between different light field scenes, adjust viewing angles, and modify environmental lighting conditions dynamically, providing flexibility while maintaining the simplicity of the light field display hardware architecture.

Implementation Method 2
A transmissive diffuser panel is mounted with the LED array, having a directly-lit diffuser panel surface having a region spaced away from the LED array by an adjustable distance D
Data Source
AI summary
A display apparatus uses an LED array having an LED pixel pitch, having LED pixels emitting light with viewing angles θ. A transmissive diffuser panel is mounted with the LED array, having a directly-lit, diffuser panel surface spaced away from the LED array by an adjustable distance D. The distance D and the viewing angles θ being are effective to merge illumination from multiple LED pixels in the LED array on the directly-lit diffuser panel surface. A controller is connected to the LED array having circuitry to control the LED array in response to image data to induce display via the diffuser panel of a time varying image with spatially varying colors and intensities.
