Multiview Static Display Using Directional Light and Aperture Barriers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic displays struggle to efficiently provide animated multiview images without relying on arrays of light valves, which limits their ability to display dynamic and perspective-rich content effectively.
Innovation Solution
A multiview display system utilizing a diffraction grating and a light guide to direct and diffract light beams, allowing for the creation of animated static images through a sequence of static images, without the need for light valves, by employing a diffraction grating to scatter light out of the guide and form directional light beams representing pixels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a static image is displayed on a display device, then the display structure remains simple and stable, but the displayed content cannot convey motion information and appears lifeless
Solution Approach 1:
The patent applies the dynamics principle by enabling the static display device to present multiple static images in sequence, creating the illusion of motion. The display device transitions from showing a single static image to cycling through a plurality of static images at a predetermined rate, thereby conveying motion information without requiring physical moving parts in the display structure itself.
Solution Approach 2:
The patent implements periodic action by displaying multiple static images in a cyclic sequence at a predetermined rate. The control unit causes the display device to alternate between different static images stored in memory, creating a periodic display pattern that human eyes perceive as motion, thus conveying dynamic information through a static physical structure.
2Adaptability or versatility
If multiple moving images are displayed simultaneously on a single display device, then motion information is conveyed effectively, but the display device becomes excessively large and complex
Solution Approach 1:
The patent applies segmentation by dividing the display of multiple moving images into separate temporal slots. Instead of displaying multiple images simultaneously on a large display area, the system segments the display time and presents one static image at a time in sequence. This allows multiple moving images to be conveyed through a single, relatively small display device by multiplexing the display content over time.
Solution Approach 2:
The patent transitions from a spatial arrangement of multiple display devices to a temporal arrangement of images on a single display device. By adding the time dimension, the system can present multiple moving images sequentially on one display, avoiding the need for multiple simultaneous displays that would require excessive display area.
3Adaptability or versatility
If a single static image is displayed on a display device, then the display structure remains simple, but the displayed content cannot convey three-dimensional spatial relationships
Solution Approach 1:
The patent applies dynamics by transitioning the display from a static single image to a dynamic sequence of multiple static images. This temporal dynamics enables the display to convey three-dimensional spatial relationships and motion information, as the human visual system integrates the sequential images to perceive depth and movement, without requiring complex three-dimensional display hardware.
Solution Approach 2:
The patent uses copying by storing multiple static images in memory that represent different views or frames of a three-dimensional scene. The control unit retrieves and displays these copied images in sequence, allowing the display device to convey three-dimensional spatial relationships through a series of two-dimensional copies rather than through complex three-dimensional display structures.

AI summary
An animated static display, animated static display system, and method provide a plurality of static images. The animated static display includes a plurality of directional scattering elements arranged across a light guide and configured to scatter out the guided light as directional light beams having different directions corresponding to the guided light being provided by different light sources. The animated static display also includes a barrier layer having different sets of apertures configured to pass directional light beams having the different directions to provide corresponding different static images of the static image plurality. The animated static display system further includes a mode controller configured to selectively activate the different light sources to provide an animated image comprising the different static images.
