Non-Rectangular Display Panel Edge Color Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-rectangular shape display panels exhibit abnormal colors and jagged edges at irregular edges, degrading display performance due to uneven light mixing from sub-pixels.
Innovation Solution
A non-rectangular shape display panel with pixels arranged in rows and columns, featuring sub-pixels with specific color filters, where the area ratio of filters in intersecting and non-intersecting pixels is maintained equal, and white color filters are used to suppress jagged edges and abnormal colors by ensuring uniform light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If non-rectangular shape display panel is used to satisfy diversified user demands, then adaptability is improved, but abnormal colors and jagged edges appear at irregular edges
Solution Approach 1:
The patent applies local quality by configuring pixels at irregular edges with specific color filter area ratios that match interior pixels, while interior pixels follow standard configurations. This localized differentiation ensures uniform light emission at edges without compromising the overall non-rectangular shape adaptability
Solution Approach 2:
The patent changes the parameter of color filter area ratios specifically at pixels intersecting irregular edges to match the ratios of non-edge pixels. This parameter adjustment ensures consistent light emission characteristics across the entire display panel, eliminating abnormal colors and jagged edges at irregular boundaries
2Manufacturing precision
If white color filter is added to sub-pixel to suppress abnormal colors, then display performance is improved, but device complexity increases
Solution Approach 1:
The white color filter is applied locally only to sub-pixels at irregular edges that require color correction, rather than uniformly across the entire display. This localized application suppresses abnormal colors at edges while maintaining standard configurations in interior regions, thereby limiting the increase in device complexity

AI summary
A non-rectangular shape display panel comprises a non-rectangular shape display region and a non-display region. The non-rectangular shape display region includes a plurality of pixels arranged in both a row direction and a column direction. A pixel includes at least three sub-pixels of different colors, a first color sub-pixel having a first color filter, a second color sub-pixel having a second color filter, and a third color sub-pixel having a third color filter. The non-rectangular shape display region includes at least one irregular edge intersecting the row direction and the column direction. The pixels intersecting the at least one irregular edge are first pixels and the remained pixels are second pixels. A first pixel is divided by the at least one irregular edge into a first light-transmitting region configured in the non-rectangular shape display region and a first light-shielding region shielded by a black matrix.
