Display Diagnosis Device White Color Gamut Notification

Solution Overview

Problem

The color gamut of a display can vary with the setting value of a white color, leading to situations where target colors cannot be displayed, requiring users to reset the color profile, which is time-consuming and inefficient.

Innovation Solution

A display diagnosis device that receives a white color setting value from a user, identifies the color gamut based on characteristics data, and notifies the user if a target color is not within this gamut, allowing for pre-adjustment diagnostics to prevent incorrect color reproduction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the color profile is adjusted to display a desired white color, then the white color reproduction is improved, but other target colors may not be able to be displayed

Engineering Contradiction:

Improvewhite color reproduction accuracyVSAvoidcolor gamut coverage

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The system performs preliminary diagnosis by identifying the color gamut based on characteristics data before the user adjusts the color profile. This allows the system to predict which target colors can be reproduced and which cannot, enabling users to make informed decisions about white color settings without having to repeatedly adjust and test the color profile

Inventive Principle:

Principle #10Preliminary action

2Manufacturing precision

If the user resets the color profile to display target colors, then color reproduction is improved, but time and effort are consumed

Engineering Contradiction:

Improvecolor reproduction accuracyVSAvoidtime for color profile adjustment

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The system performs preliminary diagnosis by identifying the color gamut based on characteristics data before the user adjusts the color profile. This allows the system to predict which target colors can be reproduced and which cannot, enabling users to make informed decisions about white color settings without having to repeatedly adjust and test the color profile

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system provides feedback to the user by displaying information about which target colors can and cannot be reproduced within the identified color gamut. This feedback mechanism guides users in making appropriate white color setting decisions, eliminating the need for trial-and-error adjustments and reducing the time required for color profile setup

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If the color gamut is expanded to include more target colors, then color versatility is improved, but white color reproduction accuracy may deteriorate

Engineering Contradiction:

Improvecolor gamut coverageVSAvoidwhite color reproduction accuracy

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The system performs preliminary diagnosis by identifying the color gamut based on characteristics data before the user adjusts the color profile. This allows the system to predict which target colors can be reproduced and which cannot, enabling users to make informed decisions about white color settings without having to repeatedly adjust and test the color profile

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system allows users to adjust the white color setting parameters (such as white point and brightness) and automatically identifies the resulting color gamut. This enables users to find the optimal balance between white color reproduction accuracy and color gamut coverage by observing how different parameter settings affect the identifiable color range and target color reproduction capability

Inventive Principle:

AI summary

A display diagnosis device includes a processor configured to: receive a setting value of a white color on a display from a user; based on characteristics data and the setting value of the white color, the characteristics data being a combination of input color data representing a color and a color measurement value obtained by measuring a color displayed based on the input color data on the display, identify a color gamut that is a part of a color space that is able to be displayed on the display; and in a case where a target color is not present within the identified color gamut, notify the user that the target color is not able to be reproduced on the display.
