Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passive electronic displays, which do not emit light, are limited in practical applications due to their inability to emit light, necessitating the use of external light sources for functionality, which can be cumbersome.
Innovation Solution
A multiview display system that employs an adjustable convergence plane with a multiview backlight configured to emit directional light beams converging at specific points, allowing for optimal viewing angles and adjustable distance between the backlight and light valves to maintain image quality across different views.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If passive displays are coupled to an external light source to enable light emission, then the display can function as an active display, but the device complexity and operational cumbersome nature increase
Solution Approach 1:
The patent merges the backlight unit and display panel into an integrated structure where the backlight is positioned directly behind the display panel at a optimized distance, eliminating the need for separate external light sources. The backlight unit includes light guides and diffusers that are structurally integrated with the display assembly, creating a unified device that functions as both light source and display.
Solution Approach 2:
The patent introduces a diffuser layer as an intermediary component between the backlight and display panel. This diffuser mediates the light transmission by scattering and distributing light uniformly across the display panel, enabling the passive display to function with active display characteristics without requiring complex external illumination systems.
2Ease of operation
If the distance between backlight and light valves is adjusted to shift convergence plane, then viewing distance can be optimized, but the structural complexity increases
Solution Approach 1:
The patent implements a adjustable backlight positioning mechanism that allows the distance between the backlight unit and light valve array to be dynamically changed. This dynamic adjustment capability enables the convergence plane to be shifted, optimizing viewing distance for different applications while maintaining a relatively simple structural implementation through movable mounting brackets or spacers.

AI summary
A multiview display includes a multiview backlight configured to emit directional light beams configured to converge at points within a convergence plane, and an array of light valves configured to modulate the directional light beams at the convergence plane. A distance between the multiview backlight and the light valve array is configured to be adjustable to shift a corresponding location of the convergence plane relative to the multiview display.
