Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing personal immersive display devices suffer from visible pixel grids and heterogeneity between left and right eye images due to low resolution and alignment of display panels, reducing user immersion.

Innovation Solution

The device employs offsetting and differing configurations of first and second display panels, including varying resolutions and pixel structures, along with image processing to down-sample and geometrically align images, minimizing grid visibility and heterogeneity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If display panels are arranged at the same position for left and right eyes, then alignment is simple, but pixel grid becomes visible and heterogeneity occurs

Engineering Contradiction:

Improvealignment simplicityVSAvoidpixel grid visibility

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent applies asymmetry by offsetting the display panels for left and right eyes by half a pixel distance. This asymmetric arrangement causes the pixel grids to be misaligned, allowing light from one panel to overlap and fade the pixel grid of the other panel, thereby reducing visible pixel grids while maintaining manufacturing feasibility

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The patent changes the positional parameter of the display panels from aligned positions to offset positions (half pixel distance). This parameter change transforms the pixel grid visibility issue by creating overlapping light fields that fade the grid patterns, resolving the contradiction between alignment simplicity and grid visibility

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If display resolution is increased to reduce pixel grid visibility, then device complexity and cost increase

Engineering Contradiction:

Improvepixel grid visibilityVSAvoiddisplay system complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

Instead of increasing resolution, the patent changes the positional parameter of the display panels by half a pixel distance. This parameter change creates overlapping light fields that fade pixel grids, achieving grid visibility reduction without increasing device complexity or cost

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent introduces light overlap as an intermediary mechanism. The light from one display panel acts as a mediator that fades the pixel grid of the other panel, providing a low-cost solution to reduce pixel grid visibility without requiring higher resolution displays

Inventive Principle:

Principle #24Intermediary (Mediator)
