TPV Display Technology (Xiamen) Co., Ltd. — 4 prefixes (MA-L)

TPV Display Technology (Xiamen) Co., Ltd. holds four IEEE MA-L blocks — A8:4A:63, 94:BD:BE, 60:C4:18, and 00:D2:B1 — all registered to a single legal entity at No. 1, Xianghai Road, Xiamen Torch Hi-Tech Industrial Development Zone, in Xiamen, Fujian, China. The Xiamen site is the largest television production base of the TPV Technology group, the world's largest monitor manufacturer by volume, and is principally engaged in the R&D, manufacture, and sale of LCD/OLED televisions and LCD modules (LCM). Because of that, addresses from these four prefixes overwhelmingly surface on smart TVs and network-connected monitors shipping under the Philips (licensed), AOC, Envision, and TP Vision brands, alongside OEM units built for other display vendors. On a typical network these MACs appear on the wired Ethernet interface of a smart TV reaching out for streaming and over-the-air firmware updates, and less often on monitors with USB-C or KVM-hub networking — most commonly on home and hospitality LAN segments, where in an enterprise capture they usually indicate guest or AV equipment rather than managed IT assets. Note that the legal entity is distinct from TPVision Europe B.V. (Amsterdam, NL) and TPV Audio and Visual Technology (Shenzhen) Co., Ltd., which hold their own separate MA-L allocations.

Registration date

Unknown — IEEE publishes NO assignment/registration date in its public OUI data (oui.csv columns are only Registry, Assignment, Organization Name, Organization Address). Third-party tools show artifact timestamps (e.g. maclookup.app lists "2019-08-09" for 00:D2:B1 and "2025-08-20" for 60:C4:18); these are database artifacts from when the aggregator recorded the entry, NOT IEEE-issued dates.

IANA reference

not applicable — MAC OUIs are administered by IEEE, not IANA; there is no IANA reference column for OUI registrations [Confirmed] — IEEE Registration Authority

Registry spelling note

the IEEE data carries two spellings of the same entity — "TPV Display Technology(Xiamen) Co.,Ltd." (no space before the parenthesis, on A8:4A:63) and "TPV Display Technology (Xiamen) Co.,Ltd." (the other three blocks). All four resolve to the same Xiamen address. [Confirmed] — file:enrichment/registries/oui.csv

Security context

no CVEs or public advisories were found attributed specifically to "TPV Display Technology (Xiamen)" as a vendor. Smart TVs and connected monitors of this class (Philips/AOC) are a broadly documented consumer-electronics/IoT attack surface (firmware OTA, HbbTV/DLNA exposure), but no named vulnerability ties to this subsidiary; security posture is Unknown for this entity specifically. [Unknown] — no source surfaced

Analyst note

a TPV-Xiamen OUI on a globally-administered address reliably flags a display device (TV or monitor) from the TPV group. Treat these as AV/consumer endpoints, not managed IT; on enterprise segments they typically indicate guest or signage gear.
