Visionox Technology Inc. (Chinese: 维信诺; Shenzhen Stock Exchange: 002387), commonly "Visionox," is a publicly traded Chinese display manufacturer. Its OLED business traces to a 1996 Tsinghua University OLED project group; the operating company was founded in 2001. The listed vehicle was formerly Blackcow Food Co., Ltd. and was renamed Visionox Technology Inc. in June 2018. It is headquartered in Beijing (Haidian) with a registered address in Kunshan, Jiangsu. Public sources put headcount at roughly 6,000 (end-2025), FY2024 revenue at about RMB 7.9 billion with a net loss of roughly RMB 2.5 billion, and market capitalization near CNY 10 billion. Largest shareholder is Xizang Zhithe Technology Development Co. (about 19%).
Visionox designs and manufactures AMOLED display panels — rigid and flexible — for smartphones (roughly 5–8 inch), smart wearables, laptops and tablets, and automotive displays, plus micro-LED development. Its proprietary ViP (Visionox intelligent Pixelization) technology uses photolithographic, fine-metal-mask-free pixel patterning. Manufacturing includes a Gen-5.5 line in Kunshan and Gen-6 flexible lines in Hefei, Langfang and Guangzhou. The company reports top-three global smartphone AMOLED shipments and first-place wearable AMOLED shipments. It spun off its OLED lighting business (Yeolight, 2015) and PMOLED business (Qingyue, 2021).
Litigation posture: Visionox is an operating company, not a non-practicing entity. The case data shows one tracked appearance, all as plaintiff and none as defendant, in a single PTAB proceeding — consistent with a defensive, co-petitioner role rather than a patent-assertion campaign.
Notable case: Mianyang BOE Optoelectronics et al. v. Samsung Display Co., Ltd. (IPR2024-00620, filed March 6, 2024), challenging U.S. Patent 9,330,593 on stage circuits for OLED displays. Visionox is a co-petitioner alongside BOE, China Star Optoelectronics (CSOT) and Tianma Microelectronics. The petitions responded to Samsung Display's December 2022 ITC complaint and 2023 Eastern District of Texas action against BOE. A final written decision issued in September 2025 finding some challenged claims unpatentable; the matter proceeded to the Federal Circuit (No. 26-1092), where Samsung Display's cross-appeal was dismissed in April 2026.
