Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Display devices, such as near-to-eye displays, experience issues like lag, judder, and trailing due to movement, leading to poor visual effects and user experience, as the displayed image is not accurately aligned with the viewer's perspective.

Innovation Solution

A method and apparatus that acquire movement information of the display device, adjust the display image distance of objects based on this information, and control the display to ensure the image is rendered at the correct distance, thereby improving the visual effect and user experience by minimizing perceived lag and trailing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the display device moves during operation, then the device can be used in mobile applications and worn devices, but lag, judder, and trailing effects occur causing poor visual quality

Engineering Contradiction:

Improvemobile application capabilityVSAvoidvisual display precision

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The system performs preliminary actions by predicting future display image distances based on current movement information and displaying images at these predicted distances in advance. This preliminary positioning compensates for the delay inherent in real-time rendering, preventing lag and trailing effects when the device moves during mobile applications.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements dynamics by continuously adjusting the display image distance based on real-time movement information from sensors. The display system dynamically changes focal lengths and image positions to match the device's current state, maintaining visual precision despite movement in mobile and wearable applications.

Inventive Principle:

Principle #15Dynamics

2Manufacturing precision

If the display image distance is adjusted dynamically based on movement information, then visual effect and user experience are improved, but the device complexity increases

Engineering Contradiction:

Improvedisplay image distance precisionVSAvoidcontrol system complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system employs feedback mechanisms where movement information from sensors is continuously fed back to the display control module. This feedback loop enables automatic adjustment of display image distance based on actual device movement, achieving precise visual alignment without requiring complex manual control systems.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent replaces complex mechanical adjustment mechanisms with electronic and optical solutions. By using electronic sensors to detect movement and optical systems (such as adjustable focal length lenses) to change image distance, the system achieves precise display control without bulky mechanical components, thereby reducing overall device complexity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
