Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing display technologies from different brands exhibit manufacturing differences leading to inconsistent color tones when multiple displays are used simultaneously, necessitating a system to optimize color consistency across multiple screens.

Innovation Solution

A display parameter adjustment system that sets one display as a reference and another as an adjustment display, using a processor to detect models, display reference and adjustment images, and adjust parameters through an intuitive interface to match color tones across displays.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple displays from different brands are used simultaneously, then display functionality and versatility are improved, but color tone consistency deteriorates due to manufacturing differences

Engineering Contradiction:

Improvedisplay functionalityVSAvoidcolor tone consistency

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent adjusts display parameters (brightness, color temperature, hue, saturation) of the adjustment display to match the reference display, resolving color tone inconsistencies while maintaining multi-display functionality

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent copies the color tone characteristics from the reference display to the adjustment display by detecting and replicating key visual parameters, achieving color consistency across different display devices

Inventive Principle:

Principle #26Copying

2Device complexity

If traditional OSD mode or remote controller is used for adjusting display parameters, then device complexity is reduced, but adjustment intuitiveness and ease of operation deteriorates

Engineering Contradiction:

Improveadjustment systemVSAvoidparameter adjustment intuitiveness

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The patent replaces traditional mechanical/physical adjustment methods (OSD menus, remote controllers) with a visual interface displayed directly on the screen, allowing users to adjust parameters by observing the actual display output and making intuitive modifications

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The adjustment interface is displayed directly on the adjustment display itself, allowing users to see and modify parameters on the same device being adjusted, eliminating the need for separate control devices and improving operational intuitiveness

Inventive Principle:

Principle #25Self-service

AI summary

A display parameter adjustment method includes providing a first display and a second display, setting the first display as a reference display and setting the second display as an adjustment display, detecting models of the first display and the second display for generating an initial configuration environment of the second display, displaying a reference image on the first display and displaying an adjustment image on the second display according to the initial configuration environment, displaying an adjustment interface on the second display, adjusting a plurality of parameters of the second display by using the adjustment interface to make the adjustment image be consistent with the reference image, and modifying configurations of the second display according to a plurality of adjusted parameters to make screen colors of the second display be consistent with screen colors of the first display.
