Display Device Modulation Region Depth for Eye Strain Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prolonged use of display panels in electronic devices leads to eye strain and potential eye health issues due to constant exposure to light, as viewers tend to reduce their blinking rate when watching content for extended periods.
Innovation Solution
A method and display device that periodically change the three-dimensional depth of a modulation region in an image, mimicking the viewer's natural blinking rhythm by adjusting the modulation distance between the left-eye and right-eye content images, thereby inducing subliminal blinking and reducing eye strain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If display panels are used for prolonged periods to provide continuous content viewing, then productivity and entertainment value are improved, but eye strain and eye health deteriorate due to reduced blinking rate
Solution Approach 1:
The patent applies periodic action by modulating the depth of the modulation region at specific time intervals that correspond to the natural blinking rhythm of human eyes. The depth modulation is performed periodically to induce subliminal blinking, ensuring that eyes blink at appropriate intervals even during prolonged content viewing, thereby preventing eye strain while maintaining continuous display functionality.
Solution Approach 2:
The patent uses the modulation region depth as an intermediary element to indirectly stimulate blinking. Instead of directly controlling eye movement or using external devices, the system modulates the depth perception of a specific region in the displayed content, which serves as a mediator to trigger the natural blinking reflex without disrupting the overall viewing experience.
2Object-affected harmful factors
If the depth of modulation region is changed to induce blinking, then eye health is improved, but image distortion occurs in the modulation region
Solution Approach 1:
The patent applies local quality by applying depth modulation only to a specific modulation region within the displayed content rather than the entire image. This localized approach allows the system to induce blinking through depth changes in a confined area, minimizing the visual impact and preventing noticeable image distortion while still achieving the eye health benefit.
Solution Approach 2:
The patent uses partial action by modulating the depth of only a portion of the displayed content (the modulation region) rather than the entire image. This partial modulation is sufficient to trigger the blinking reflex while avoiding excessive changes that would cause noticeable distortion or disrupt the overall image quality and viewing experience.
3Object-affected harmful factors
If modulation distance is adjusted to create three-dimensional depth, then eye blinking is induced, but complexity of image processing increases
Solution Approach 1:
The patent applies segmentation by dividing the displayed content into a modulation region and a non-modulation region. Only the modulation region undergoes depth adjustment through left-eye and right-eye image separation, while the rest of the content remains unchanged. This segmented approach reduces the overall processing complexity compared to applying depth modulation to the entire image.
Solution Approach 2:
The patent uses partial action by applying complex depth modulation processing only to a specific portion of the image (the modulation region) rather than the entire content. This selective processing reduces computational complexity and processing requirements while still achieving the desired effect of inducing blinking through three-dimensional depth changes in the modulation region.

AI summary
A method of display an image and a display device for performing the same are disclosed. In one aspect, the method includes receiving image data for a content image, determining a modulation region and a peripheral region in the content image and generating a left-eye content image and a right-eye content image based on the image data for the content image such that the modulation region has a three-dimensional depth. The method further includes displaying the left-eye content image and the right-eye content image and periodically changing the three-dimensional depth of the modulation region by changing a modulation distance between the modulation region in the left-eye content image and the modulation region in the right-eye content image based at least in part on a periodic modulation reference timing.
