Solution Overview

Problem

Existing image display systems with multiple devices of different characteristics, such as projectors and displays, face challenges in maintaining continuity of contrast and chromaticity due to external light conditions, leading to impaired immersion in multimedia shows or games.

Innovation Solution

An image display system equipped with external light detection devices and image adjustment mechanisms that adjust contrast, chromaticity, and luminance settings based on device characteristics and detected external light conditions, ensuring that multiple image display devices present a unified and continuous image to the user.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple image display devices with different device characteristics are used to display images, then the display coverage and versatility are improved, but the continuity of contrast and chromaticity between devices deteriorates

Engineering Contradiction:

Improvedisplay coverageVSAvoidcontinuity of contrast and chromaticity

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The system changes display parameters (contrast, chromaticity, luminance) of image display devices based on detected external light conditions and device characteristics, enabling continuous adjustment to maintain image continuity across different devices

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The external light detection device provides feedback about ambient light conditions to the image adjustment device, which then adjusts display parameters accordingly to maintain continuity between different image display devices

Inventive Principle:

Principle #23Feedback

2Device complexity

If image display devices operate without adjustment under varying external light conditions, then the device complexity is reduced, but the image quality and immersion experience deteriorate

Engineering Contradiction:

Improvesystem simplicityVSAvoidimage quality consistency

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The image adjustment device automatically adjusts display parameters based on external light detection and device characteristics without requiring manual intervention, enabling the system to self-optimize image quality

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system pre-stores device characteristics of multiple image display devices and uses this information along with real-time light detection to proactively adjust display parameters before image quality degradation occurs

Inventive Principle:

Principle #10Preliminary action
