Non-Rectangular Pixel Array for Smooth Display Contours
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional non-rectangular display devices with rectangular pixels suffer from jagged edges, irregular color display, and reduced aperture rate due to the rectangular shape of pixels, leading to poor design flexibility and display quality, especially when attempting to depict smooth curved contours or hollow shapes.
Innovation Solution
A non-rectangular pixel array with intersecting conductor lines that surround each pixel, allowing for a smooth and gentle outer shape without sacrificing brightness or viewability, and enabling the creation of complex shapes like hollow apertures, by using non-rectangular pixels arranged in various configurations such as triangular or hexagonal shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If rectangular pixels are used in non-rectangular display devices, then the display device can be manufactured with simple pixel structures, but the outer shape becomes jagged and display quality deteriorates
Solution Approach 1:
The patent applies curvature by replacing rectangular pixel shapes with circular or polygonal pixels that have curved edges. This allows the pixel array to form smooth outer contours while maintaining regular pixel structures that are easy to manufacture. The circular/polygonal pixel geometry inherently provides curved boundaries that eliminate the jagged edges problem.
Solution Approach 2:
The patent segments the pixel array into multiple regular polygonal or circular pixel units arranged in a grid pattern. Each pixel is a complete geometric shape with curved edges, and their collective arrangement forms the overall non-rectangular display shape with smooth contours, resolving the contradiction between simple manufacturing and smooth appearance.
2Adaptability or versatility
If rectangular pixels are arranged to form non-rectangular shapes, then design flexibility is limited, but manufacturing remains straightforward
Solution Approach 1:
The patent uses universal circular or polygonal pixel units that can be arranged to form various non-rectangular display shapes (oval, circular, irregular contours). This single pixel geometry serves multiple design purposes, providing high adaptability while maintaining simple, regular pixel structures that are easy to manufacture and control.
Solution Approach 2:
The curved geometry of circular/polygonal pixels provides inherent design flexibility for creating smooth non-rectangular display shapes. The universal curved pixel unit can be arranged in various patterns to achieve different overall display contours, enhancing adaptability without increasing pixel structure complexity.
3Device complexity
If rectangular pixels are used with orthogonal conductor lines, then conductor line arrangement is simple, but aperture rate decreases due to line intersections
Solution Approach 1:
The patent replaces orthogonal straight conductor lines with curved conductor lines that follow the circular or polygonal pixel boundaries. This curved conductor arrangement reduces the number and area of intersections compared to orthogonal grids, thereby increasing the aperture rate while maintaining manageable conductor line complexity through the regular curved pattern.
Solution Approach 2:
The conductor lines are locally optimized to follow the curved pixel boundaries rather than maintaining a uniform orthogonal grid. This local adaptation of conductor line geometry to the pixel shape reduces unnecessary intersections in curved regions, increasing aperture rate while keeping the overall conductor arrangement systematic and manufacturable.
4Adaptability or versatility
If rectangular pixels are arranged in non-rectangular configurations, then hollow shapes and complex contours cannot be achieved, but manufacturing remains simple
Solution Approach 1:
The patent segments the display area into multiple circular or polygonal pixel units that can be selectively activated or deactivated. This segmentation enables the formation of hollow shapes and complex contours by controlling which pixels are active, while each individual pixel remains a simple regular geometry that is easy to manufacture.
Solution Approach 2:
The curved geometry of circular/polygonal pixels naturally supports the formation of hollow shapes and smooth complex contours. The curved pixel boundaries and flexible arrangement enable organic shapes that would be difficult to achieve with rectangular pixels, while maintaining regular pixel structures for simple manufacturing.

AI summary
A non-rectangular pixel array includes non-rectangular pixels. A first conductor line group including first conductor lines and a second conductor line group including second conductor lines are arranged to intersect. Each non-rectangular pixel is arranged to be partially surrounded by one of the first conductor lines and one of second conductor lines. Each first conductor lines includes a first line and a second line which are arranged in parallel and in proximity to each other, without non-rectangular pixel existing between the first line and the second line within each first conductor line, and with non-rectangular pixels existing between adjacent the first conductor lines. Non-rectangular pixels include first pixels and second pixels. Each first pixel is arranged to be partially surrounded by the first line and the second conductor line, and each second pixel is arranged to be partially surrounded by the second line and the second conductor line.
