Non-rectangular Display Panel Pixel Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panel designs with non-rectangular shapes suffer from serrated curve edges, leading to poor display quality due to the conventional design method.
Innovation Solution
A display panel with a non-rectangular display area is designed by arranging pixel rows where end pixels with smaller display regions are placed between the inner pixels, and the area of the display regions of end pixels is gradually increased towards the inner pixels, reducing serration and improving edge smoothness.

Engineering Contradiction Analysis
1Manufacturing precision
If conventional design method is applied to non-rectangular display panels, then manufacturing simplicity is maintained, but display quality deteriorates due to serrated curve edges
Solution Approach 1:
The pixel array is segmented into three distinct types: inner pixels located within the curved edge region, end pixels positioned at the terminal positions of pixel rows, and ordinary pixels in regular positions. Each type has specifically designed display region areas to collectively achieve smooth curved edges while maintaining manageable manufacturing complexity
Solution Approach 2:
Different pixel types are assigned different display region area characteristics tailored to their specific positions. Inner pixels have smaller display regions to accommodate the curved edge geometry, end pixels have intermediate sizes, and ordinary pixels have standard sizes. This local differentiation ensures smooth visual transitions at curved edges without requiring complete redesign of the entire pixel array
2Shape
If end pixels with smaller display regions are placed at pixel row ends, then curve edge smoothness is improved, but pixel area uniformity deteriorates
Solution Approach 1:
The patent implements position-dependent pixel design where inner pixels at curved edges have smaller display regions, end pixels have intermediate areas, and ordinary pixels maintain standard sizes. This local quality variation creates smooth curved edges visually while the systematic classification into discrete pixel types maintains manufacturability
Solution Approach 2:
The display region area parameter is deliberately changed based on pixel position: inner pixels have reduced areas to follow the curved edge contour, end pixels have moderately reduced areas, and ordinary pixels maintain full area. This controlled parameter variation achieves geometric flexibility without sacrificing overall display quality

AI summary
The present invention provides a display panel including a non-rectangular display area. The display panel includes a first pixel row. The first pixel row includes a plurality of inner pixels and a plurality of end pixels. The inner pixels are disposed in the non-rectangular display area, and the end pixels are disposed between an end of the first pixel row and the inner pixels. An area of a display region of each of the end pixels is less than an area of a display region of each of the inner pixels. In the first pixel row, areas of a plurality of display regions of the end pixels are increased along a direction from the end of the first pixel row toward the inner pixels.
