Adaptive Blue Light Reduction in Display Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies emit excessive blue light, causing eye strain and disrupting sleep patterns, with existing methods either compromising picture quality or uniformly reducing blue light without adapting to image content characteristics.
Innovation Solution
A display apparatus with a processor that dynamically adjusts blue light emission based on image content characteristics, such as contrast ratio and brightness, using a lookup table to optimize color temperature and brightness settings, allowing for adaptive control to minimize user inconvenience and reduce blue light exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If blue light emission is reduced uniformly, then viewer fatigue is reduced, but picture quality deteriorates
Solution Approach 1:
The patent applies dynamics by making the blue light reduction adaptive rather than static. The system dynamically adjusts the degree of blue light reduction based on real-time detection of image content characteristics (such as contrast ratio, brightness, and color temperature) to maintain optimal picture quality while reducing blue light exposure.
Solution Approach 2:
The patent changes parameters by adjusting multiple image attributes (contrast ratio, brightness, color temperature) dynamically based on detected image characteristics. The system modifies these parameters adaptively to balance blue light reduction with picture quality preservation, rather than applying a fixed uniform reduction.
2Object-affected harmful factors
If blue light reduction is applied continuously, then viewer fatigue is reduced, but visual inconvenience increases due to sudden picture quality changes
Solution Approach 1:
The patent implements periodic action by monitoring image characteristics at regular intervals and adjusting blue light reduction levels based on detected changes. The system periodically evaluates image content characteristics and adjusts parameters accordingly, avoiding sudden changes while maintaining continuous protection.
Solution Approach 2:
The patent applies feedback by continuously detecting image characteristics (contrast ratio, brightness, color temperature) and using this information to adjust blue light reduction parameters in real-time. This closed-loop feedback mechanism ensures that picture quality remains optimal while blue light is reduced, preventing visual inconvenience.
3Device complexity
If fixed blue light reduction is applied, then implementation is simple, but adaptability to different image content is poor
Solution Approach 1:
The patent applies self-service by enabling the system to automatically detect image characteristics and adjust blue light reduction parameters without user intervention. The system self-regulates based on detected content characteristics, maintaining adaptability while keeping the control mechanism relatively simple.
Solution Approach 2:
The patent changes parameters dynamically by adjusting multiple image attributes (contrast ratio, brightness, color temperature) based on detected image characteristics. This allows the system to adapt to different image content types while maintaining a manageable control structure through automated parameter adjustment.

AI summary
A display apparatus including: a display configured to display an image; and at least one processor configured to, in response to beginning a viewer fatigue reduction function, determine whether a change characteristic of an image displayed on the display during a first time interval of an image signal corresponds to a suitable section for the viewer fatigue reduction function, and control the display to decrease a viewing fatigue level of the displayed image during the determined suitable section.
