LED Display Control Method for Reducing Visual Crosstalk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LED display technologies experience visual crosstalk and blurring of dynamic images due to the integration of light from previous and next frames, leading to a suboptimal display effect.
Innovation Solution
An image display control method that adjusts the display time of images based on the refresh rate by compressing the display time using different processing modes, such as reducing time intervals between display columns or frequency doubling, to minimize crosstalk and improve image clarity.

Engineering Contradiction Analysis
1Area of stationary object
If images are uniformly displayed over the entire time axis of a field, then the display coverage is maximized, but visual crosstalk and blurring occur due to temporal integration of light from previous and next frames
Solution Approach 1:
The patent extracts and removes the harmful temporal integration effect by compressing the display time of each frame into a shorter interval. This prevents the human eye from integrating light from previous and next frames, thereby eliminating visual crosstalk while maintaining adequate display coverage through the compressed timing arrangement
Solution Approach 2:
The patent applies dynamic adjustment by compressing display time based on the refresh rate. The display time is dynamically reduced according to the relationship between refresh rate and frame rate, allowing the system to adaptively prevent crosstalk while maintaining optimal display coverage under different operating conditions
2Manufacturing precision
If display time is compressed to reduce visual crosstalk, then image clarity improves, but the display coverage and brightness may be reduced
Solution Approach 1:
The patent changes the timing parameters by compressing display time according to the refresh rate. This parameter adjustment reduces the display interval to prevent temporal integration, thereby improving image clarity while the system compensates for coverage through optimized timing synchronization with the refresh cycle
3Manufacturing precision
If display time is compressed to prevent crosstalk, then image sharpness improves, but the luminance and visibility may be reduced
Solution Approach 1:
The patent dynamically adjusts display time based on refresh rate to compress the display interval, which prevents crosstalk and improves sharpness. The system compensates for luminance reduction by synchronizing with the refresh cycle and optimizing the timing to ensure adequate light output within the compressed window
