Polygonal Sub-Pixel Arrangement for High Resolution Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices have limited resolution due to the rectangular or square shape of sub-pixels, which restricts the number of pixel rows and columns, thereby limiting the display's resolution and color reproduction capabilities.
Innovation Solution
A display panel with unit pixels featuring a first sub-pixel of a polygonal shape, a second sub-pixel of a rectangular shape, and a third sub-pixel of a polygonal shape, where the first and third sub-pixels are symmetrically arranged with respect to the second sub-pixel, allowing for a hexagonal or octagonal overall shape, enabling a higher density of pixels and improved color reproduction by emitting different colors.

Engineering Contradiction Analysis
1Manufacturing precision
If sub-pixels are arranged in a conventional rectangular or square shape, then the structure is simple and easy to manufacture, but the resolution of the display device is limited
Solution Approach 1:
The patent applies asymmetry by changing from conventional symmetric rectangular/square sub-pixel arrangements to an asymmetric configuration where the first and third sub-pixels have polygonal shapes with five or more sides, while the second sub-pixel has a rectangular shape. This asymmetric arrangement allows for increased pixel density and higher resolution without compromising manufacturability, as the asymmetric design enables more efficient space utilization within each unit pixel.
2Manufacturing precision
If the number of pixel rows and columns is increased to improve resolution, then the display quality improves, but the distance between adjacent unit pixels increases
Solution Approach 1:
The patent applies dimensionality change by transitioning from traditional rectangular sub-pixel shapes to polygonal shapes with five or more sides. This geometric transformation allows sub-pixels to pack more efficiently in two-dimensional space, enabling increased pixel density without increasing the physical distance between adjacent unit pixels. The polygonal configuration optimizes space utilization, allowing more pixels to be accommodated within the same display area.
