Display Apparatus Blue Light Adjustment for Health Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The emission of blue light from display apparatuses poses health risks, including eye fatigue, retinal damage, and sleep disturbances, due to its harmful effects on the human body.
Innovation Solution
A display apparatus and control method that adjust the blue (B) value of images based on user information such as gender, age, eyesight, and viewing habits, including viewing time, position, and posture, to reduce the harmful effects of blue light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the blue light emission is maintained for high image quality, then the image display quality is improved, but the harmful effects on human health worsen
Solution Approach 1:
The patent changes the blue component parameter of the display based on user characteristics (age, eyesight) and viewing conditions (viewing time, position, posture). The controller dynamically adjusts the blue light intensity parameter to reduce harmful effects while maintaining acceptable image quality. This resolves the contradiction by making the blue light emission variable rather than fixed, adapting it to minimize health risks in different scenarios.
2Object-affected harmful factors
If the blue value is reduced to protect user health, then the harmful effects are minimized, but the image quality may deteriorate
Solution Approach 1:
The patent implements dynamic adjustment of the blue value based on real-time or detected user information and viewing habits. Rather than a static reduction, the system continuously adapts the blue light intensity according to changing conditions (different users, different viewing scenarios, different times of day). This dynamic approach allows image quality to be preserved when appropriate while reducing harm when necessary, resolving the contradiction between health protection and quality maintenance.
3Object-affected harmful factors
If the display adjusts blue light based on detailed user information and viewing habits, then the health protection effectiveness is improved, but the device complexity increases
Solution Approach 1:
The patent enables the display to automatically detect and process user information (such as age, eyesight) and viewing habits (viewing time, position, posture) without requiring manual input or complex user setup. The system self-adjusts the blue light parameters based on this detected information, reducing the need for complex user interfaces or manual configuration while achieving effective health protection. This self-service approach improves health protection effectiveness without proportionally increasing device complexity.

AI summary
A display apparatus includes: a display configured to display an image; an image processor configured to process the displayed image; and a controller configured to control the image processor to adjust a blue (B) value of red (R), green (G), and B values constituting the image based on at least one of information about a user and information about a viewing habits of the user.
