Flexible Display Image Compensation via Angle Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display panels experience image distortion and delayed real-time compensation when bent or folded, as conventional methods require determining the final bent angle before executing image processing, leading to a delay in displaying the compensated image.
Innovation Solution
A display system comprising a prediction unit to forecast the bent angle, a compensation unit to generate initial and predicted compensation images, and an image synthesis unit to synthesize a display image, allowing for immediate substitution on the flexible panel, utilizing algorithms like Seam-Carving, Scale-and-Stretch, or Feathering to minimize distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the conventional approach waits for determination of the final angle before executing image processing, then the image compensation accuracy is improved, but the display delay increases
Solution Approach 1:
The patent applies preliminary action by predicting the final bent angle in advance before the bending operation is completed. The prediction unit forecasts the final angle based on initial bending information, allowing the compensation unit to pre-process the display image according to this predicted angle. This enables real-time compensation without waiting for the final angle determination, thus reducing display delay while maintaining compensation accuracy.
2Loss of time
If real-time image compensation is implemented on flexible panels, then display delay is reduced, but image distortion may occur when the final angle differs from prediction
Solution Approach 1:
The patent implements feedback by comparing the predicted final angle with the actual final angle after bending. When the actual angle differs from the predicted angle, the system performs additional image processing to generate a second compensated image based on the actual angle. This feedback mechanism ensures image accuracy is maintained even when predictions deviate from reality, resolving the reliability concern.
3Manufacturing precision
If multiple image processing algorithms are used for compensation, then image quality is improved, but processing complexity increases
Solution Approach 1:
The patent applies dynamics by making the image processing approach adaptive rather than static. The system dynamically selects between different processing strategies: using only prediction-based compensation when accurate, or combining prediction with feedback-based correction when needed. This dynamic adaptation maintains high image quality while avoiding unnecessary processing complexity in straightforward cases.
