Dual-Contour Display Panel Pixel Layout for Smooth Curved Edges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels with non-rectangular shapes exhibit a zigzag or grainy appearance at their contours due to the arrangement of pixels along smooth curves, affecting visual quality.
Innovation Solution
A display panel design featuring a primary contour line with non-linear first portions and a secondary contour line inside it, with specific types of pixels positioned relative to these lines to achieve smooth grayscale transitions and reduce the zigzag effect, using varying aperture ratios and light-shielding patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pixels are arranged along a smooth contour line of a special-shaped display panel, then the display panel can achieve diversified shapes (spherical, polyhedral, etc.), but the pixel arrangement exhibits an obvious zigzag or grainy appearance at micro-scale
Solution Approach 1:
The patent applies local quality by differentiating pixel aperture ratios based on their position relative to the contour line. Pixels closer to the contour line have smaller aperture ratios, while pixels farther away have larger aperture ratios. This localized adjustment of pixel properties compensates for the zigzag effect at the contour, maintaining visual smoothness while preserving the special shape of the display panel.
2Manufacturing precision
If the aperture ratio of pixels near the contour line is reduced, then the zigzag effect is minimized and visual quality improves, but the brightness and light output of those pixels decrease
Solution Approach 1:
The patent changes the aperture ratio parameter of pixels based on their spatial position relative to the contour line. By dynamically adjusting this parameter - smaller aperture ratios near the contour and larger aperture ratios in the interior - the patent achieves both visual quality improvement and maintains adequate brightness through compensatory design in the overall pixel array configuration.

AI summary
A display panel and a display device are provided. The display panel includes: a primary contour defining an active display region and including first portions extending non-linearly, a secondary contour inside the primary contour and including second portions extending non-linearly; the primary contour is an outer contour after the display panel is lightened; pixels in the active display region include pixels of first type inside the secondary contour, pixels of second type intersecting the second portion, and pixels of third type intersecting the first portion and outside the secondary contour; an aperture ratio of pixels of third type is smaller than that of pixels of first type, an aperture ratio of at least part of pixels of second type is positively correlated with an area of a part, inside the secondary contour, of each pixel of second type.
