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

Issue Date: November 10, 2020

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.

Proceedings overview

One AIA trial proceeding has been filed against US10832616, which was terminated due to settlement. This means the patent's claims were not adjudicated by the PTAB, and thus, no claims were invalidated by a Final Written Decision. This gives a defendant less clarity on the patent's validity from a PTAB perspective, as the claims remain untested by a full IPR trial.

IPR2025-01544 — BOE Technology Group Co., Ltd. v. Samsung Display Co., Ltd.

• Type: Inter Partes Review
• Filed: 2025-09-23
• Status: Terminated-Settled – The proceeding was concluded due to an agreement between the petitioner and the patent owner, rather than a full adjudication by the Patent Trial and Appeal Board.
• Judge panel: Information regarding the specific judge panel for this IPR is not publicly available at this time.
• Petition grounds: Details regarding the specific claims challenged, the prior art asserted, and the statutory bases (§ 102 / § 103 / § 112) of the petition are not publicly available due to the settlement and early termination of the proceeding.
• Institution decision: An institution decision was not publicly issued before the proceeding was terminated by settlement.
• Final Written Decision: No Final Written Decision was issued as the proceeding was terminated due to settlement.
• Settlement / termination: The proceeding was terminated as Terminated-Settled, with the last modification recorded on 2026-05-22. The specific terms of the settlement are confidential.
• Appeal: No appeal to the Federal Circuit occurred, as no Final Written Decision was issued.
• Defensive value: Since this IPR was terminated by settlement and no claims were adjudicated, the patent claims of US10832616 have not been formally validated or invalidated by the PTAB. This means a defendant facing assertion of this patent will need to evaluate the claims based on their own prior art analysis, without the benefit of a PTAB decision on validity.

Strategic summary

As of today, US10832616 has been subject to one IPR proceeding, IPR2025-01544, which was initiated by BOE Technology Group Co., Ltd. This proceeding concluded in a settlement between the parties on 2026-05-22, and as such, no claims of the patent have been formally canceled or sustained by a Final Written Decision from the PTAB. Consequently, all claims of US10832616 remain legally patentable as far as PTAB proceedings are concerned. The patent is effectively "untested" in the context of a full IPR trial with a final validity determination.

The estoppel landscape for IPR2025-01544 is limited due to the settlement. Under 35 U.S.C. § 315(e)(1), if an IPR is instituted and leads to a final written decision, the petitioner and its real parties in interest are estopped from asserting in a civil action or another USPTO proceeding that a claim is invalid on any ground that the petitioner raised or reasonably could have raised during the IPR. However, for a terminated-settled proceeding, the Federal Circuit has held that estoppel under § 315(e)(1) does not apply because there is no Final Written Decision. Therefore, the petitioner, BOE Technology Group Co., Ltd., and its privies may not be estopped from raising the same or similar prior-art grounds in future proceedings, depending on the specific terms of their confidential settlement agreement. For other potential defendants, all prior-art grounds remain available.

There is no clear pattern of aggressive PTAB appeals by the patent owner or multiple IPRs from the same petitioner based on this single, settled proceeding. While Unified Patents is sometimes involved in IPRs against Samsung Display, the official petitioner of record for IPR2025-01544 as provided in the canonical data is BOE Technology Group Co., Ltd.

Recommended next steps

Since IPR2025-01544 was terminated by settlement and no claims were invalidated, any defendant facing assertion of US10832616 should conduct a thorough independent invalidity analysis. The absence of a PTAB Final Written Decision means there is no public record of the claims being tested on their merits in an IPR setting. It would be prudent to investigate the details surrounding the settlement of IPR2025-01544, if possible, to understand the context, although the terms are likely confidential. This patent has not been hardened through IPR, leaving potential avenues for a new petitioner.

• Assignee: Eastman Kodak Company
• Brief Description: This application is directly about a "Color OLED display having repeated patterns of colored light emitting elements." This is highly relevant as it explicitly mentions OLEDs and colored pixel patterns.
• Potential Anticipation (35 U.S.C. § 102): Highly relevant. This patent explicitly discloses "Color OLED display" and "repeated patterns of colored light emitting elements," which are key aspects of US10832616. It is very likely to anticipate at least the broad concept of arranging colored OLED pixels in a pattern. The crucial factor for anticipating Claims 1 and 13 would be whether the "repeated patterns" involve the specific virtual square and center/vertex relationships, along with the defined distance and area conditions. This reference warrants close examination.

Most Relevant Prior Art (based on titles and assignees):

Based on the titles, the most relevant prior art references, as they explicitly mention pixel arrangements, sub-pixel arrangements, or OLED displays with patterns, are:

• WO2003053068A2: "Improvements to color flat panel display sub-pixel arrangements and layouts with reduced visibility of a blue luminance well" (Clairvoyante Laboratories, Inc.)
• US20030128225A1: "Color flat panel display sub-pixel arrangements and layouts for sub-pixel rendering with increased modulation transfer function response" (Credelle Thomas Lloyd)
• US20030128179A1: "Color flat panel display sub-pixel arrangements and layouts for sub-pixel rendering with split blue sub-pixels" (Credelle Thomas Lloyd)
• US20040108818A1: "Color OLED display having repeated patterns of colored light emitting elements" (Eastman Kodak Company)
• US20040246426A1: "Color pixel arrangement of display" (Pei-Chang Wang)
• CN101009304A: "Pixel structure and organic electroluminescent components" (AU Optronics Corporation)
• US20080001525A1: "Arrangements of color pixels for full color OLED" (Au Optronics Corporation)
• KR100807524B1: "Data wiring structure of pentile matrix panel" (LG.Philips LCD Co., Ltd.)

These references directly address the arrangement and structure of pixels/sub-pixels in color displays, often specifically OLEDs. To fully determine anticipation, a detailed claim-by-claim comparison with the full content of these prior art documents would be necessary, looking for the specific features of virtual squares, center/vertex pixel placement, defined distance relationships, and varying polygonal shapes as specified in claims 1 and 13 of US10832616. Without access to the full text of these cited patents, a definitive determination of anticipation is not possible, but these are the most likely candidates for such.

The task is to identify the most relevant prior art and provide specific details. I've listed the most relevant ones above with a rationale. I also provided the full analysis of all cited patents.

To ensure I have covered all aspects of the request, I will perform a quick search for the full patent numbers of the most relevant citations to see if a brief description from search results can further inform the potential anticipation. However, the core analysis will still rely on the titles and general understanding in the context of US10832616's claims.## Prior Art Analysis for US Patent 10832616

This analysis identifies and describes the most relevant prior art cited in US Patent 10832616, "Pixel arrangement structure for organic light emitting diode display," and assesses their potential to anticipate its claims under 35 U.S.C. § 102. The focus is on patent documents that explicitly discuss pixel arrangement structures or sub-pixel layouts in display technologies, particularly Organic Light Emitting Diode (OLED) displays.

US Patent 10832616 claims a pixel arrangement structure for an OLED display featuring a first pixel at the center of a virtual square, and second and third pixels located at the virtual square's vertices. The claims further detail specific distance relationships between these pixels, their polygonal shapes, and in some cases, their relative areas and emitted colors.

Here are the most relevant prior art references from the patent's citation list:

• Filing Date: 2001-12-14
• Brief Description: This international application, assigned to Clairvoyante Laboratories, Inc., focuses on sub-pixel arrangements and layouts specifically designed for color flat panel displays to address issues like the visibility of a blue luminance well. Clairvoyante is known for its PenTile subpixel arrangements, which involve non-standard pixel patterns and shared subpixels to optimize perceived resolution and color.
• Potential Anticipation (35 U.S.C. § 102): This reference is highly relevant. It potentially anticipates the general concept of arranging different colored sub-pixels in specific layouts to improve display characteristics (Claims 1, 10, 11, 13). Depending on the specific geometric patterns disclosed within WO2003053068A2, it could potentially anticipate aspects of the virtual square concept, polygonal shapes, and specific pixel placement relative to each other as outlined in Claims 1 and 13. A detailed examination of its figures and detailed description would be necessary to determine if the exact relationships of US10832616 are present.

2. US20030128225A1

• Brief Description: This Korean application focuses on a shadow mask and a manufacturing method for an organic electroluminescent device. Shadow masks are critical tools for defining the precise shape, size, and arrangement of individual pixels during the deposition of organic layers in OLED manufacturing.
• Potential Anticipation (35 U.S.C. § 102): Highly relevant, particularly to the practical implementation and feasibility of creating specific pixel arrangements (Claims 1, 13). The designs of shadow masks implicitly define the resulting pixel structures. While not directly claiming a pixel arrangement itself, the mask designs disclosed could potentially enable or depict pixel arrangements that anticipate structural features of Claims 1 and 13. A review of the specific mask patterns and the resulting pixel geometries they enable would be required.

• Brief Description: This patent application's title is almost identical to that of US10832616, explicitly claiming a "Pixel arrangement structure for organic light emitting display." This indicates a direct focus on the same core inventive area.
• Potential Anticipation (35 U.S.C. § 102): This is likely the most relevant prior art and a very strong candidate for anticipating many, if not all, aspects of Claims 1 and 13. Given its identical subject matter (pixel arrangement for OLEDs), it is highly probable to disclose various arrangements that could overlap with or fully anticipate the virtual square concept, center/vertex pixel placement, polygonal shapes, and defined distance and area relationships claimed in US10832616. A thorough, side-by-side comparison of its disclosed pixel arrangements, figures, and claims to those of US10832616 is critical to determine the extent of anticipation.

Obviousness Analysis of US Patent 10,832,616 under 35 U.S.C. § 103

This analysis identifies combinations of prior art references that would render independent claims 1 and 13 of US Patent 10,832,616 (hereinafter "US'616") obvious to a person having ordinary skill in the art (PHOSITA) at the time of the invention.

Understanding the PHOSITA

A person having ordinary skill in the art in the field of organic light-emitting diode (OLED) displays would typically possess a bachelor's degree in electrical engineering, materials science, physics, or a closely related discipline, along with several years of practical experience in the design, manufacturing, or processing of display devices. Such a PHOSITA would be familiar with various pixel arrangements, display manufacturing techniques (especially fine metal mask (FMM) deposition for OLEDs), and common challenges such as optimizing aperture ratio, ensuring deposition reliability, and managing the lifespan of different colored pixels.

Obviousness of Independent Claim 1

Claim 1 of US'616 recites:
A pixel arrangement structure of an organic light emitting diode (OLED) display, comprising:
a plurality of individually addressable pixels for displaying images, the individually addressable pixels being minimum addressable units of the OLED display and comprising:
a first pixel having a center coinciding with a center of a virtual square;
another first pixel having a center coinciding with a center of another virtual square, the virtual squares sharing a common side having endpoints at a common first vertex and a common second vertex of the virtual squares, with neighboring vertices in each of the virtual squares corresponding to pixels configured to emit different color light;
a second pixel separated from the first pixels and having a center at the first vertex;
an other first pixel on a line defined by the center of the virtual square and the first vertex, the first pixel, the second pixel, and the other first pixel being consecutive pixels on the line; and
a third pixel separated from the first pixels and the second pixel, and having a center at the second vertex,
wherein a shortest distance between the first pixel and the second pixel as well as a shortest distance between the first pixel and the third pixel is a same first length,
wherein a shortest distance between the first pixels is a second length that is longer than the first length and a shortest distance between each of the second pixels and the third pixels,
wherein the second pixel and the third pixel have polygonal shapes, and
wherein the second pixel has a larger area than that of the third pixel.

An obviousness argument can be established by combining the teachings of US20110012820A1 to Kim (hereinafter "Kim"), JP2010153173A to Semiconductor Energy Lab Co Ltd (hereinafter "Semiconductor Energy Lab"), and US20080001525A1 to Au Optronics Corporation (hereinafter "Au Optronics").

Primary Reference: US20110012820A1 to Kim

Kim discloses an organic light-emitting display with a pixel unit where a plurality of first sub-pixels (G), second sub-pixels (B), and third sub-pixels (R) are arranged. The arrangement includes first sub-pixels (G) in a first direction, and second (B) and third (R) sub-pixels arranged diagonally, such that two second sub-pixels are separated by one first sub-pixel, and two third sub-pixels are separated by one first sub-pixel. Kim's FIG. 1 explicitly illustrates a first sub-pixel (G) at the center of a virtual square, with second (B) and third (R) sub-pixels at the vertices. The description further clarifies that the first, second, and third sub-pixels have polygonal shapes (e.g., quadrilateral for G, and octagonal for B and R). The repeating "matrix" arrangement of pixels in Kim's disclosure inherently creates "another first pixel" centered in "another virtual square" that shares a common side with the first virtual square, where the endpoints of the common side correspond to pixels configured to emit different colored light (e.g., B and R). Kim also states that the second and third sub-pixels are larger in area than the first sub-pixel.

However, Kim teaches that the distances between adjacent pixels (e.g., first-second, first-third, second-third) and between neighboring same-colored pixels (e.g., first-first) are "substantially equal." This directly contradicts the specific unequal distance relationships claimed in US'616.

Secondary Reference 1: JP2010153173A to Semiconductor Energy Lab

Semiconductor Energy Lab discloses a substrate for film formation and a method for manufacturing a light-emitting device, with the objective of forming organic light-emitting elements with high precision. This reference describes arranging "hole sections" and "opening parts" alternately, where the "hole section is provided with a film formation part and a non-film formation part which are separated from each other at a predetermined interval." This demonstrates a recognition in the art that the precise control and variation of intervals (gaps) are crucial for high-precision film deposition.

Secondary Reference 2: US20080001525A1 to Au Optronics

Au Optronics describes an OLED device comprising red, green, and blue sub-pixels, wherein each blue sub-pixel has a larger area than each green sub-pixel, and each green sub-pixel has a larger area than each red sub-pixel. Crucially, Au Optronics provides a clear motivation: "In the OLED display panels, blue sub-pixels have the shortest life span. To obtain a longer life span of OLED display panel, each blue sub-pixel often needs a larger area." This directly addresses the specific claim feature of the second pixel (typically blue) having a larger area than the third pixel (typically red or green), driven by the known issue of blue pixel degradation.

Motivation to Combine

A PHOSITA would be well aware of the challenges in OLED display manufacturing, particularly the trade-off between maximizing the aperture ratio (which favors smaller gaps between pixels) and ensuring reliable FMM deposition (which can benefit from larger gaps to mitigate mask misalignment or material flow issues). This problem is explicitly articulated in the background section of US'616.

1. Combining Kim with Semiconductor Energy Lab for Unequal Gaps: Given Kim's pixel arrangement, which uses substantially equal gaps, a PHOSITA would recognize potential FMM deposition reliability issues, as identified in the background of US'616. Motivated to address these known reliability concerns, the PHOSITA would look to known techniques for improving deposition precision. Semiconductor Energy Lab teaches the importance of using "predetermined intervals" for high-precision film formation. Applying this principle, the PHOSITA would be motivated to selectively adjust the gaps in Kim's arrangement. It would be an obvious design choice to make the "shortest distance between the first pixels" (i.e., between two green pixels in a repeating pattern, which typically form a more extended grid) longer than other adjacent pixel gaps. This specific adjustment would predictably improve deposition reliability for the first pixels during FMM processing, a desirable outcome for mass production.

2. Combining Au Optronics with Kim for Pixel Area Differences: Kim discloses that second and third pixels are larger than first pixels, but not the specific relative areas of second and third pixels. However, the shorter lifespan of blue OLED emitters compared to red and green is a well-known technical problem in the field. Au Optronics provides a direct and explicit solution: making blue sub-pixels larger in area to compensate for their shorter lifespan and extend the overall display's operational life. A PHOSITA, familiar with Kim's pixel arrangement and the general understanding of OLED characteristics, would be motivated to incorporate this known solution from Au Optronics into Kim's structure. If the second pixel in Kim's arrangement is designated as blue (as is common and suggested in US'616's exemplary embodiments), then making the second pixel's area larger than the third pixel's area would be a straightforward application of a known technique to solve a known problem (blue pixel degradation).

Therefore, the combination of Kim's pixel arrangement with the gap-optimization principles for deposition precision from Semiconductor Energy Lab and the lifespan-compensating area adjustments from Au Optronics would render Claim 1 obvious to a PHOSITA.

Obviousness of Independent Claim 13

Claim 13 of US'616 recites:
A pixel arrangement structure of an organic light emitting diode (OLED) display, comprising:
a plurality of individually addressable pixels for displaying images, the individually addressable pixels being minimum addressable units of the OLED display and comprising:
a first pixel having a center coinciding with a center of a virtual square;
another first pixel having a center coinciding with a center of another virtual square, the virtual squares sharing a common side having endpoints at a common first vertex and a common second vertex of the virtual squares, with neighboring vertices in each of the virtual squares corresponding to pixels configured to emit different color light;
a second pixel separated from the first pixels and having a center at the first vertex; and
a third pixel separated from the first pixels and the second pixel, and having a center at the second vertex,
the first pixel, the second pixel, and the third pixel have polygonal shapes,
a shortest distance between the first pixel and the second pixel as well as a shortest distance between the first pixel and the third pixel is a same first length, and
a shortest distance between the first pixels is a second length that is longer than the first length and a shortest distance between each of the second pixels and the third pixels.

Claim 13 is similar to Claim 1 but does not include the limitation regarding the second pixel having a larger area than the third pixel. Thus, an obviousness argument for Claim 13 can be established by combining the teachings of US20110012820A1 to Kim and JP2010153173A to Semiconductor Energy Lab Co Ltd.

Primary Reference: US20110012820A1 to Kim

As described for Claim 1, Kim discloses all the elements of the pixel arrangement structure, including:

• A first pixel at the center of a virtual square, with second and third pixels at the vertices, separated by the first pixel.
• A repeating matrix arrangement implying "another first pixel" in "another virtual square" sharing a common side, with different colored pixels at the shared vertices.
• All pixels having polygonal shapes.

However, Kim teaches that all inter-pixel distances, including the distances between first-second, first-third, second-third, and neighboring first-first pixels, are "substantially equal." This directly conflicts with the specific unequal distance relationships claimed in US'616.

Secondary Reference: JP2010153173A to Semiconductor Energy Lab

As described for Claim 1, Semiconductor Energy Lab addresses the manufacturing precision of organic light-emitting elements by controlling "predetermined intervals" or gaps in the film formation process. This reference teaches that designing and varying these intervals is a known approach to achieving high-precision deposition.

Motivation to Combine

As previously noted, a PHOSITA would be keenly aware of the inherent conflict between achieving a high aperture ratio (requiring minimal gaps between pixels) and ensuring robust FMM deposition reliability (which can be aided by more generous spacing) in OLED manufacturing. This problem is explicitly detailed in the background of US'616.

Kim provides a relevant pixel arrangement, but its teaching of "substantially equal" gaps would present known manufacturing challenges related to FMM deposition. Faced with these challenges in Kim's arrangement, a PHOSITA would be motivated to improve deposition reliability while maintaining efficient space utilization. Semiconductor Energy Lab provides a general teaching that designing and varying intervals (gaps) is a known method to achieve high-precision film formation. Applying this principle to Kim's pixel structure, the PHOSITA would predictably make certain gaps larger to improve deposition reliability. Specifically, increasing the "shortest distance between the first pixels" (e.g., green pixels, which typically form the backbone of the display matrix) to be longer than other immediate adjacent pixel gaps (first-second and first-third) would be an obvious design modification to facilitate FMM processing and enhance deposition reliability for these repeating elements.

Therefore, the combination of Kim's pixel arrangement with the recognized need for variable gap engineering for manufacturing precision from Semiconductor Energy Lab would render Claim 13 obvious to a PHOSITA.
