Bent Display Panel Image Distortion Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flat panel display devices face challenges in maintaining display quality due to image distortion caused by their flat structure, particularly when bent, leading to variations in color, brightness, and chroma that are not uniform across the display surface.
Innovation Solution
A curved display device with an organic light emitting display panel featuring a first flat display part and a second bent display part, where the control module adjusts the color, brightness, and chroma of the gradation image along the bending axis to compensate for image distortion, ensuring uniformity in these attributes parallel to the axis and varying them across directions perpendicular to it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flat panel display device is bent to create a curved display, then the display form factor and adaptability are improved, but image distortion occurs causing non-uniform color, brightness, and chroma across the display surface
Solution Approach 1:
The patent applies local quality by dividing the display panel into different regions (first display part and second display part) with different bending characteristics. The first display part remains substantially flat while the second display part is bent, allowing each region to maintain optimal display quality for its specific geometric configuration. This resolves the contradiction by enabling curved form factors while preserving image uniformity in critical display areas.
Solution Approach 2:
The patent changes physical parameters by controlling the bending radius and curvature of different display regions. By adjusting the bending parameters of the second display part while keeping the first display part flat, the system achieves a curved overall form factor while maintaining uniform color, brightness, and chroma in the flat display region, thus resolving the image distortion issue.
2Adaptability or versatility
If the entire display panel is bent to achieve a curved shape, then the display versatility is improved, but the display quality deteriorates due to image distortion and non-uniformity
Solution Approach 1:
The patent segments the display panel into functionally distinct regions: a first display part that remains substantially flat for high-quality imaging, and a second display part that is bent to provide curved display capability. This segmentation allows the system to achieve versatility through curvature while maintaining reliability in the flat display region where image quality is critical.
Solution Approach 2:
Different quality standards are applied to different regions: the first display part maintains uniform color, brightness, and chroma characteristics suitable for high-quality imaging, while the second display part accommodates curved geometry. This local quality approach resolves the contradiction between curved versatility and display reliability.
3Ease of manufacture
If color, brightness, and chroma are kept uniform across the entire display surface, then manufacturing simplicity is maintained, but image distortion becomes apparent in bent regions
Solution Approach 1:
The patent implements local quality control by setting uniform color, brightness, and chroma parameters for the first display part while allowing different parameter characteristics in the second bent display part. This approach maintains manufacturing simplicity in the flat region while achieving image distortion compensation through regional parameter differentiation.

AI summary
A display device includes an organic light emitting display panel and a control module. The organic light emitting display panel includes a first display part and a second display part bent from the first display part with respect to a bending axis and configured to display a gradation image. The control module is configured to control images displayed in the first and second display parts. At least one of color, brightness, and chroma of the gradation image is varied along a direction crossing the bending axis of the organic light emitting display panel. A user perceives that an image distortion caused by a shape of the organic light emitting display panel is caused by the gradation image.
