Summary of US Patent 10,832,616: Pixel Arrangement Structure for Organic Light Emitting Diode Display

Title: Pixel arrangement structure for organic light emitting diode display

Assignee: Samsung Display Co Ltd

Inventors: Sang-Shin Lee

Filing Date: April 26, 2013

Abstract: The patent describes a pixel arrangement structure for an organic light emitting diode (OLED) display. This structure includes a first pixel centered within a virtual square, a second pixel located at a first vertex of the virtual square, and a third pixel at a second vertex neighboring the first vertex. All these pixels have polygonal shapes. The design aims to improve the aperture ratio of each pixel while maintaining efficient gaps between them.

Plain-Language Overview of Independent Claims:

Independent Claim 1:
This claim describes an OLED display pixel arrangement with multiple individually addressable pixels. It specifies a "first pixel" at the center of a "virtual square" and "another first pixel" at the center of "another virtual square," where these virtual squares share a common side. A "second pixel" is positioned at a "first vertex" (an endpoint of the common side) and a "third pixel" at a "second vertex" (the other endpoint of the common side). The claim details specific distance relationships: the shortest distance between the first pixel and the second pixel, and between the first pixel and the third pixel, is a "same first length." The shortest distance between the "first pixels" (meaning the original first pixel and the "another first pixel") is a "second length" which is longer than the "first length" and also longer than the shortest distance between the second and third pixels. Furthermore, the second and third pixels have polygonal shapes, and the second pixel has a larger area than the third pixel.

Independent Claim 13:
Similar to claim 1, this independent claim also describes an OLED display pixel arrangement with individually addressable pixels. It includes a "first pixel" centered in a "virtual square" and "another first pixel" in "another virtual square," with the virtual squares sharing a common side. A "second pixel" is at a "first vertex" and a "third pixel" at a "second vertex" (the endpoints of the common side). All these first, second, and third pixels have polygonal shapes. The claim specifies that the shortest distance between the first pixel and the second pixel, and between the first pixel and the third pixel, is a "same first length." Crucially, the shortest distance between the "first pixels" is a "second length" that is longer than the "first length" and also longer than the shortest distance between each of the second and third pixels.

Litigation Status:

US Patent 10,832,616 is currently active and is scheduled to expire on May 22, 2034.

The patent family has ongoing litigation. A US case was filed in the Texas Eastern District Court (case number 2:25-cv-00430).

Additionally, a PTAB case, IPR2025-01544, was filed, which has since reached a settlement.

No specific dockets for the US Court of Appeals for the Federal Circuit (CAFC) in 2026 were directly found in the provided patent text or search results. While general CAFC information was found, no specific case linked to US10832616 for 2026 was identified.
