Display Device Static Area Interpolation Edge Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display device techniques that insert interpolated frames to improve display quality often result in blurring between moving objects or extend the image beyond its intended length, especially when dealing with multiple moving objects or objects that suddenly appear or disappear.
Innovation Solution
A method and device for setting static areas in previous and current frames by comparing edge areas and using these static areas unmodified in interpolated frames, thereby reducing errors and improving display quality.

1Manufacturing precision
If motion vector derived interpolated frames are inserted among original frames, then display quality is improved by providing additional interpolated frames, but blurring occurs between discrete moving objects or images extend beyond their intended length
Solution Approach 1:
The image is divided into multiple blocks, and motion vectors are extracted for each block individually. This segmentation allows different regions of the image to be processed differently, enabling accurate representation of discrete moving objects while preventing unwanted interpolation in static regions.
Solution Approach 2:
Different interpolation strategies are applied to different regions based on their motion characteristics. Regions with significant motion use motion-compensated interpolation, while static or slowly varying regions use simple averaging or remain unchanged, preventing blurring in areas where it would be harmful.
2Productivity
If interpolated frames are generated using motion vectors from previous and current frames, then frame rate is increased by inserting additional frames, but images may extend beyond their intended length when objects suddenly appear or disappear
Solution Approach 1:
The interpolation process dynamically adjusts based on motion detection. When significant motion or sudden appearance/disappearance of objects is detected, the system modifies the interpolation strategy to prevent images from extending beyond their intended length, while still maintaining high frame rates for smoother motion in stable regions.
Solution Approach 2:
The system changes interpolation parameters based on the specific characteristics of each frame and region. By adjusting motion vector weights, block sizes, and interpolation methods according to detected motion patterns, the system maintains accurate image timing and length even during sudden object appearance or disappearance events.

AI summary
A display device with improved display quality and a method of driving the display device set at least one static area in each of a previous frame and a current frame by comparing edge areas of the previous frame and edge areas of the current frame, and create an interpolated frame for display between the previous and current frames. At least one static area of the previous frame is used in an unmodified state as a static area of the interpolated frame.
