Prior Art Cited in US Patent 11626066:

Here is a list of prior art patents cited in US11626066, along with their publication/filing dates, a brief description, and potential claims they may anticipate under 35 U.S.C. § 102. Please note that a definitive determination of anticipation would require a detailed claim-by-claim analysis, but general areas of overlap can be identified.

1. US4491863A

• Full Citation: US4491863A - Color display apparatus
• Publication Date: 1985-01-01 (Priority Date: 1979-12-04)
• Brief Description: This patent describes a color display apparatus. While specific details of pixel arrangement are not provided in the snippet, general color display technology forms a foundational background.
• Potential Anticipated Claims: Could potentially anticipate general concepts of a display device displaying images with different colored pixels, as broadly mentioned in the background of independent claims 1 and 15. However, it is unlikely to anticipate the specific geometric arrangements and relative sizing of pixels detailed in US11626066.

2. US4642619A

• Full Citation: US4642619A - Non-light-emitting liquid crystal color display device
• Publication Date: 1987-02-10 (Priority Date: 1982-12-15)
• Brief Description: This patent pertains to a non-light-emitting liquid crystal color display device. This is distinct from an OLED display in its light-emission mechanism but contributes to the general field of color displays.
• Potential Anticipated Claims: Similar to US4491863A, it might touch upon the broad concept of displaying color images. However, it is highly unlikely to anticipate specific OLED pixel arrangements or the unique challenges related to FMM deposition in OLEDs.

3. EP0322106A2

• Full Citation: EP0322106A2 - Display device
• Publication Date: 1989-06-28 (Priority Date: 1987-11-28)
• Brief Description: This European patent describes a display device. Without further details from the patent itself, its specific relevance to pixel arrangement in OLEDs is unclear but generally contributes to display technology.
• Potential Anticipated Claims: Broad aspects of display device architecture.

4. US4965565A

• Full Citation: US4965565A - Liquid crystal display panel having a thin-film transistor array for displaying a high quality picture
• Publication Date: 1990-10-23 (Priority Date: 1987-05-06)
• Brief Description: This patent describes an LCD panel with a thin-film transistor array for high-quality pictures. Again, this is an LCD technology, not OLED.
• Potential Anticipated Claims: General display panel concepts, but not the specific OLED pixel structure or manufacturing method.

5. JPH0336239A

• Full Citation: JPH0336239A - Austenitic iron-base alloy
• Publication Date: 1991-02-15 (Priority Date: 1989-07-04)
• Brief Description: This Japanese patent describes an austenitic iron-base alloy. This appears to be unrelated to display technology or pixel arrangements. It is likely cited for a tangential aspect or as part of a broader material science context that may not directly anticipate the core claims of US11626066.
• Potential Anticipated Claims: Highly unlikely to anticipate any claims related to pixel arrangement or display technology.

6. JPH0378390A

• Full Citation: JPH0378390A - Liquid crystal display device
• Publication Date: 1991-04-03 (Priority Date: 1989-08-21)
• Brief Description: This Japanese patent relates to a liquid crystal display device.

• Brief Description: This patent describes a color LCD with light shielding layers and its manufacturing method.
• Potential Anticipated Claims: Concepts related to display manufacturing and light control in displays, but specific pixel geometries and OLED manufacturing are distinct.

9. US5461503A

• Full Citation: US5461503A - Color matrix display unit with double pixel area for red and blue pixels
• Publication Date: 1995-10-24 (Priority Date: 1993-04-08)
• Brief Description: This patent describes a color matrix display unit where red and blue pixels have double the area. This is highly relevant as it addresses differing pixel areas for different colors, a feature present in claims 1 and 15 of US11626066 (e.g., blue pixels having a larger area than red pixels, and larger than green pixels).
• Potential Anticipated Claims: Could potentially anticipate aspects of claims 1 and 15 related to the relative areas of different colored pixels (e.g., "each of the at least two blue pixels has a larger area than each of the at least two red pixels," and "each of the at least two blue pixels has a larger area than that of the first green pixel"). However, the specific arrangement in a virtual square and the polygonal shapes described in US11626066 would likely differentiate it.

10. US5485293A

• Full Citation: US5485293A - Liquid crystal display including color triads with split pixels
• Publication Date: 1996-01-16 (Priority Date: 1993-09-29)
• Brief Description: This patent describes an LCD with color triads and split pixels. This deals with pixel organization for color displays.

11. JPH08227276A

• Full Citation: JPH08227276A - Organic electroluminescence display panel and manufacturing method thereof
• Publication Date: 1996-09-03 (Priority Date: 1995-02-21)
• Brief Description: This Japanese patent specifically describes an organic electroluminescence display panel and its manufacturing method. This is highly relevant as it directly addresses OLED technology and manufacturing. It could potentially anticipate aspects of OLED structure and manufacturing, especially the use of deposition for organic emission layers.
• Potential Anticipated Claims: Could potentially anticipate the general use of an organic emission layer for different colors, and the manufacturing method using deposition. The specific pixel arrangement and relative sizes/shapes would be the differentiating factors for US11626066.

12. JPH08335060A

• Full Citation: JPH08335060A - Driving method of matrix type color liquid crystal display device
• Publication Date: 1996-12-17 (Priority Date: 1996-06-28)

Summary of Most Relevant Prior Art:

Based on the titles and descriptions, the most relevant prior art citations that could potentially anticipate aspects of US11626066 under 35 U.S.C. § 102 are:

• US5461503A (Color matrix display unit with double pixel area for red and blue pixels): This patent directly addresses the concept of differing pixel areas for different colors, which is a key feature in claims 1 and 15 of US11626066.
• JPH08227276A (Organic electroluminescence display panel and manufacturing method thereof): This patent describes OLED panel technology and manufacturing methods, which are central to US11626066.
• JPH1039791A (Organic electroluminescence display device): Similar to JPH08227276A, this patent directly pertains to OLED display devices.
• JP2000235891A (Organic electroluminescent device): Another directly relevant OLED technology patent.

While these patents demonstrate knowledge of varying pixel sizes or OLED technology and manufacturing, the unique combination of geometric arrangement (e.g., first pixel at the center of a virtual square, second and third pixels at vertices), specific polygonal shapes (e.g., quadrilateral, hexagonal, octagonal), and precise spatial relationships (shortest distances) as defined in claims 1 and 15 of US11626066 would be the key elements for novelty and non-obviousness.
