Curved-Edge Display Panel Aperture Layout for Color Stripe Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels with arc or circular screens suffer from visible sawtooth and color stripes at the edges, affecting display quality and user experience due to uneven color mixing and sub-pixel gaps.
Innovation Solution
A display panel design with non-rectangular sub-pixel opening regions adjacent to curved boundaries, where the ratio of the area of these opening regions is adjusted to reduce the difference in size and brightness, minimizing color stripe formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If sub-pixels are arranged in a regular rectangular pattern, then manufacturing is simple and consistent, but visible sawtooth and color stripes appear at curved edges
Solution Approach 1:
The patent applies different aperture ratios to sub-pixels based on their location: sub-pixels at curved edges have smaller aperture ratios than those in the center. This local differentiation eliminates color stripes at curved boundaries while maintaining regular rectangular arrangement elsewhere, resolving the contradiction between manufacturing simplicity and visual quality.
2Illumination intensity
If sub-pixel opening regions are made larger to increase brightness, then display brightness improves, but color stripe artifacts become more visible at edges
Solution Approach 1:
The patent creates a spatial gradient in aperture ratios where sub-pixels at curved edges have smaller openings and central sub-pixels have larger openings. This local quality variation ensures that edge sub-pixels don't produce excessive brightness that would highlight color stripes, while central sub-pixels maintain high brightness for overall display quality.
3Adaptability or versatility
If the display region boundary is made curved for aesthetic purposes, then product design flexibility improves, but visible sawtooth artifacts appear at the boundary
Solution Approach 1:
The patent maintains a regular rectangular sub-pixel arrangement throughout the display, but applies local quality adjustment by reducing aperture ratios specifically at sub-pixels near curved boundaries. This approach preserves the aesthetic curved boundary while preventing sawtooth artifacts through localized parameter modification rather than changing the overall arrangement pattern.
