Digital Display Image Arrangement to Prevent OLED Sticking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital display devices with organic light emitting display panels experience an image sticking phenomenon when displaying images with similar color groups consecutively, leading to degraded image quality.
Innovation Solution
A digital display device with an image arrangement method that calculates data subtraction values for pairs of images to determine an optimal display order, ensuring images with similar color groups are displayed with the longest time interval between them, thereby preventing consecutive display and minimizing the image sticking effect.

1Productivity
If images with similar color groups are displayed consecutively to maximize utilization of display content, then display efficiency is improved, but image sticking phenomenon occurs causing image quality to degrade
Solution Approach 1:
The image arrangement unit pre-calculates data subtraction values for all possible pairs of images before display, and pre-determines the optimal display order. This preliminary arrangement ensures that images with similar color groups are separated by sufficient time intervals, preventing image sticking while maintaining efficient display utilization.
Solution Approach 2:
The system changes the display parameter of time interval between images based on their color similarity. By calculating data subtraction values and arranging images with smallest subtraction values (most similar colors) to have maximal time intervals, the system dynamically adjusts display timing parameters to prevent image sticking while maintaining high display efficiency.
2Reliability
If images are arranged with longest time interval between similar color groups to prevent image sticking, then image quality is improved, but display efficiency decreases
Solution Approach 1:
The system optimizes the time interval parameter dynamically based on color similarity calculations. By using data subtraction values to determine precise spacing requirements, the system achieves the minimum necessary time intervals to prevent image sticking, rather than using excessive gaps, thereby maintaining display efficiency while ensuring image quality.
Solution Approach 2:
The system applies different time interval treatments to different image pairs based on their specific color similarity characteristics. Images with high color similarity receive larger time intervals, while images with low similarity receive minimal spacing. This localized, differentiated approach prevents image sticking where needed while maintaining display efficiency overall.
