Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional two-dimensional displays cannot accurately replicate the light field of natural objects, limiting their ability to create a compelling three-dimensional representation.
Innovation Solution
The development of display apparatuses that include a rotatable structure with multiple light field sub-displays, a motor to rotate the structure, and a processor to map and illuminate the sub-displays based on a stored light field image, allowing for the creation of a three-dimensional representation by simulating different viewing directions and focal depths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional two-dimensional displays are used, then the display structure is simple and easy to manufacture, but the ability to accurately replicate the light field of natural objects is limited
Solution Approach 1:
The display is divided into multiple light field sub-displays arranged in a circular array, each sub-display responsible for a specific angular segment of the light field. This segmentation allows accurate replication of light field properties while keeping each individual sub-display relatively simple in structure.
Solution Approach 2:
The patent transitions from conventional two-dimensional display to a three-dimensional light field display by adding the angular dimension. Multiple sub-displays are arranged circumferentially to emit light in different directions, creating a volumetric light field that accurately represents natural objects.
2Measurement precision
If multiple light field sub-displays are used to create three-dimensional representation, then the light field replication accuracy is improved, but the device complexity increases
Solution Approach 1:
Multiple light field sub-displays are merged into a single rotatable structure that rotates as one unit. This combining approach reduces the overall system complexity compared to having multiple independently controlled displays, while still achieving accurate three-dimensional light field replication through the coordinated rotation and selective illumination of sub-displays.
Solution Approach 2:
The rotatable structure performs periodic rotation to sequentially position different light field sub-displays at the active display location. This periodic action allows a limited number of physical sub-displays to create the effect of multiple simultaneous displays, reducing the total number of components needed.
3Adaptability or versatility
If the rotatable structure with multiple sub-displays is implemented, then the field of view and perception at various angles are improved, but the manufacturing complexity increases
Solution Approach 1:
Each light field sub-display is designed as a universal module that can function at any position in the circular array. The identical design of all sub-displays simplifies manufacturing, as the same component can be produced in quantity and assembled in different positions to achieve comprehensive viewing angle coverage.

AI summary
Apparatuses and methods for displaying a 3-D representation of an object are described. Apparatuses can include a rotatable structure, motor, and multiple light field sub-displays disposed on the rotatable structure. The apparatuses can store a light field image to be displayed, the light field image providing multiple different views of the object at different viewing directions. A processor can drive the motor to rotate the rotatable structure and map the light field image to each of the light field sub-displays based in part on the rotation angle, and illuminate the light field sub-displays based in part on the mapped light field image. The apparatuses can include a display panel configured to be viewed from a fiducial viewing direction, where the display panel is curved out of a plane that is perpendicular to the fiducial viewing direction, and a plurality of light field sub-displays disposed on the display panel.
