Eye-Tracked Display Driving for Motion Blur Reduction in HMDs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display quality is deteriorated and dizziness occurs due to motion blur in head-mounted display apparatuses.
Innovation Solution
A display apparatus adjusts the duty ratio and frequency of the display area based on eye tracking to reduce the perception of motion blur by distinguishing between a central viewing area and a peripheral viewing area, driving them at different duty ratios or frequencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display panel operates at a uniform duty ratio across the entire display area, then the control is simple and power consumption is balanced, but motion blur is perceived uniformly causing deteriorated display quality and dizziness
Solution Approach 1:
The display area is segmented into a central viewing area and a peripheral viewing area based on eye tracking results. The central viewing area is driven at a first duty ratio while the peripheral viewing area is driven at a second duty ratio, allowing different regions to operate under optimized control parameters that reduce motion blur perception.
Solution Approach 2:
Different duty ratios are applied to different regions of the display panel based on their functional importance. The central viewing area receives a first duty ratio optimized for reducing motion blur in the user's focal point, while the peripheral viewing area receives a second duty ratio, creating local optimization for display quality.
2Reliability
If the central viewing area is driven at a lower duty ratio to reduce motion blur, then display quality improves, but power consumption increases for the peripheral viewing area
Solution Approach 1:
The duty ratio is dynamically adjusted based on eye tracking data that identifies the user's viewing preferences and attention focus. The system determines whether to apply a first duty ratio to the central viewing area or a second duty ratio, allowing adaptive power management that optimizes between display quality and energy consumption in real-time.

AI summary
A display apparatus includes: a display panel; an eye tracker configured to track a view of a user; and a display panel driver configured to determine a central viewing area of the display panel and a peripheral viewing area of the display panel based on the view of the user, to drive the central viewing area of the display panel at a first duty ratio, and to drive the peripheral viewing area of the display panel at a second duty ratio, wherein the first duty ratio is less than the second duty ratio.
