With [[Hewlett Packard Enterprise]] being spun off from Hewlett-Packard on November 1, 2015, and the remaining company being renamed to [[HP Inc.]], the research lab also spun off [[Hewlett Packard Labs]] to [[Hewlett Packard Enterprise]]<ref name="Hewlett Packard Labs">{{cite web|title = Hewlett Packard Labs| url=http://www.labs.hpe.com/about/ | publisher=[[Hewlett Packard Enterprise]]}}</ref> and HP Labs was kept for HP Inc.

==History==
As the Semiconductor Lab's first manager, [[Mohamed Atalla]] launched a material science investigation program that provided a base technology for [[gallium arsenide]], [[gallium arsenide phosphide]] and [[indium arsenide]] devices. These devices became the core technology used by HP's Microwave Division to develop sweepers and [[Network analyzer (electrical)|network analyzers]] that pushed 20{{ndash}}40 GHz frequency, giving HP more than 90% of the [[military communications]] market by the 1970s.<ref>{{cite book |last1=House |first1=Charles H. |last2=Price |first2=Raymond L. |title=The HP Phenomenon: Innovation and Business Transformation |date=2009 |publisher=[[Stanford University Press]] |isbn=9780804772617 |pages=110–1 |url=https://books.google.com/books?id=OsTnDv6d2DwC&pg=PA110}}</ref>

HP Labs was involved in HP's [[research and development]] (R&D) on practical [[light-emitting diode]]s (LEDs) between 1966 and 1969. The first practical [[LED display]]s were built at Atalla's Semiconductor Lab.<ref name="Borden">{{cite journal |last1=Borden |first1=Howard C. |last2=Pighini |first2=Gerald P. |title=Solid-State Displays |journal=[[Hewlett-Packard Journal]] |date=February 1969 |pages=2–12 |url=http://hparchive.com/Journals/HPJ-1969-02.pdf}}</ref> HP introduced the first commercial LED display in 1968.<ref name="Kramer">{{cite book |last1=Kramer |first1=Bernhard |title=Advances in Solid State Physics |date=2003 |publisher=[[Springer Science & Business Media]] |isbn=9783540401506 |page=40 |url=https://books.google.com/books?id=oREQToB2q2UC&pg=PA40}}</ref> In February 1969, they introduced the HP Model 5082-7000 Numeric Indicator.<ref name="Borden"/> It was the first intelligent LED display, and was a revolution in [[digital display]] technology, replacing the [[Nixie tube]] and becoming the basis for later LED displays.<ref>{{cite web |title=Hewlett-Packard 5082-7000 |url=http://www.decadecounter.com/vta/articleview.php?item=1052 |archive-url=https://web.archive.org/web/20141117052948/http://www.decadecounter.com/vta/articleview.php?item=1052 |url-status=usurped |archive-date=November 17, 2014 |website=The Vintage Technology Association |access-date=15 August 2019}}</ref>

In 1977, HP Labs fabricated prototypes of the [[DMOS]] (double-diffused MOSFET), a type of [[power MOSFET]]. They demonstrated that it was superior to the [[VMOS]] (V-groove MOSFET) with its lower on-resistance and higher breakdown voltage. The DMOS became the most common [[power transistor]] used in [[power electronics]].<ref name="powerelectronics">{{cite web |title=Advances in Discrete Semiconductors March On |url=https://www.powerelectronics.com/content/advances-discrete-semiconductors-march |website=[[Power Electronics]] |publisher=[[Informa]] |access-date=31 July 2019 |date=1 September 2005 |archive-url=https://web.archive.org/web/20060322222716/http://powerelectronics.com/mag/509PET26.pdf |archive-date=22 March 2006 |url-status=live }}</ref>

During the early 90s, HP Labs invented the concept of an [[Explicitly parallel instruction computing|Explicitly parallel instruction computing (EPIC)]] instruction set, which led to the [[Intel Itanium architecture]]. Towards the end of the 90s, HP Labs worked on a precursor to web services, known as e-Speak.<ref>{{Cite web |last=Sliwa |first=Carol |date=2002-12-02 |title=From e-Speak to Web services |url=https://www.computerworld.com/article/2578587/from-e-speak-to-web-services.html |access-date=2023-04-01 |website=Computerworld |language=en}}</ref><ref>{{Cite journal |last=Karp |first=Alan |date=2004 |title=Lessons from E-speak |url=https://www.usenix.org/legacy/publications/library/proceedings/worlds04/tech/full_papers/karp/karp.pdf |journal=Worlds 04}}</ref>

In 1999, HP Labs and [[University of California, Los Angeles|UCLA]] built the world's first molecular logic gate for eventual application in chemically assembled [[Nanocomputer|nano-computers]].<ref>{{Cite press release |title=UCLA Chemists, Hewlett-Packard Labs Colleagues Report Significant Advances Toward Chemical Computers |url=https://newsroom.ucla.edu/releases/UCLA-Chemists-Hewlett-Packard-320 |access-date=2023-10-31 |website=UCLA |language=en-US}}</ref>

During the 2000s, HP Labs in Bristol created [[Jena (framework)|Jena]], a [[semantic web]] framework.
