Visionox

Visionox Technology Inc. (维信诺科技股份有限公司; Shenzhen Stock Exchange: 002387) is a Chinese AMOLED display manufacturer. The listed entity traces to 1998 and was formerly Blackcow Food Co., Ltd., renamed Visionox Technology Inc. in June 2018; the OLED business itself was founded in 2001 with Tsinghua University-linked backing. Its registered address is in Kunshan, Jiangsu, with corporate offices in Beijing. It is publicly traded, not a subsidiary, with no controlling parent — the largest holder (Xizang Zhithe Technology Development) holds roughly 19%. Reported figures: about 6,010 employees at year-end 2025 and FY2025 revenue of roughly RMB 8.1 billion (about US$1.15 billion); the company has been loss-making on a net basis.

Products/operations. Visionox develops and manufactures OLED display devices. Its main business is AMOLED panels for smartphones, wearables, laptops/tablets, and automotive displays, with micro-LED as a stated second line. Production sites include a Gen-5.5 rigid line in Kunshan and Gen-6 flexible lines in Hefei, Hebei, and Guangzhou. It spun off OLED lighting (Yeolight, 2015) and PMOLED (Qingyue, 2021). It reports more than 10,000 OLED-related patent applications and has led work on international OLED standards. This is an operating manufacturer, not a patent-assertion entity.

Litigation posture. Case data show one tracked appearance — as plaintiff, zero as defendant — at the USPTO/PTAB. That appearance is as a co-petitioner, not a standalone assertion: Visionox joined BOE (Mianyang BOE Optoelectronics), Wuhan China Star (TCL CSOT), and Tianma Microelectronics in inter partes reviews challenging Samsung Display OLED patents, including U.S. 7,414,599 (IPR2023-00941) and 9,330,593 (IPR2023-01221), filed in 2023. So Visionox's tracked posture is an operating company participating in a joint defensive/counteroffensive invalidity campaign, not an NPE suit, and no district-court venue (e.g., Eastern District of Texas) appears in its tracked cases.

Context. The PTAB filings responded to Samsung Display's December 2022 ITC Section 337 complaint (Inv. No. 337-TA-1351) over AMOLED panels, part of a broader multi-jurisdiction BOE–Samsung Display dispute. The '599 challenges failed (final written decision, December 2024, no claim unpatentable); in the '593 review the Board found some claims unpatentable in September 2025. BOE and Samsung Display settled in November 2025.
