Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with curved transparent panels suffer from non-linear image distortion and color distortion due to the refractive effects at the edges, degrading user experience and visual appearance.
Innovation Solution
A display method that involves shrinking image data and refracting it through the curved deformation area of the transparent panel, using techniques such as pixel weighting and luminance compensation to maintain image clarity and prevent distortion, thereby ensuring a clear and smooth display effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a curved transparent panel is used to hide the bezel and improve appearance, then the visual appearance is improved, but non-linear image distortion and color distortion occur due to light refraction
Solution Approach 1:
The patent applies preliminary action by pre-processing the image data to compensate for the expected optical distortion before display. The processor calculates distortion compensation data based on the curved panel's optical characteristics and applies this compensation to the image content in advance, so that the distortion introduced by the curved panel results in a corrected final image.
Solution Approach 2:
The patent changes parameters by adjusting image data parameters (pixel positions, colors, brightness) according to the optical deformation parameters of different regions. The processor divides the display area into multiple regions with different optical characteristics and applies different compensation parameters to each region, thereby correcting the overall image distortion.
2Shape
If the curved edge of the transparent panel is made wider to improve the bezel-hiding effect, then the appearance is improved, but the image distortion becomes more severe
Solution Approach 1:
The patent applies local quality by treating different regions of the display area differently. The processor divides the display area into multiple regions based on their optical deformation characteristics, with the curved panel region being one such area. Each region receives customized distortion compensation tailored to its specific optical properties, allowing the curved edge to be wider while maintaining image quality through region-specific correction.
3Device complexity
If image data is not pre-processed for distortion compensation, then the processing complexity is reduced, but the displayed image suffers from non-linear distortion and color distortion
Solution Approach 1:
The patent introduces an intermediary element - the distortion compensation data - that mediates between the image data and the curved transparent panel. This compensation data acts as a corrective layer that accounts for the optical distortion, allowing the system to maintain both the aesthetic benefits of the curved panel and the quality of the displayed image without requiring complex real-time processing.
