What Buwon Precision Sciences Co. does

Buwon Precision Sciences Co., Ltd. is a Taiwan-based precision thin-film coating manufacturer that produces ITO (Indium Tin Oxide) coated glass substrates, capacitive touch panel (CTP) sensors, optical coatings (AR, IR-cut, half mirror, EMI shielding), metal-coated glass, EC mirror glass, and Micro LED glass backplanes. The company operates from its headquarters and main manufacturing facility in the Guanyin Industrial Zone, Taoyuan City, Taiwan, with vertically integrated production spanning vacuum magnetron sputtering, photo-etching (photolithography), and downstream cutting and CM module assembly — claimed to be the only Taiwanese ITO glass factory with this complete coating-to-module capability on a single site. Underlying technology includes DITO (Double-side ITO) processing for X/Y patterning on a single glass substrate, multi-layer optical coating stacks using SiO2/Nb2Ox/Si3Nx materials, and metal coating formulations (Mo/Al/Mo, Ti/Cu, Cr/Ag), with maximum substrate size of 1,200 x 2,000mm (Gen 6/85 inch) and combined sputtering capacity exceeding 1.2 million sheets per month across three production lines.

The company serves six primary verticals — medical devices, automotive, large outdoor displays, consumer electronics/touch, home appliances/smart home, and wearables — with named enterprise customers including Samsung (PDP Filter), SMK, Hosiden, and Futaba (automotive touch panels). Buwon holds IATF 16949:2016, ISO 9001:2015, and ISO 14001:2015 certifications, and emphasizes 1,000-hour reliability testing for automotive-grade products. It operates dedicated regional sales offices for Taiwan, Japan, Korea, Europe/Americas, and China, executing a direct enterprise field-sales motion with custom-spec B2B hardware orders rather than standardized SKU pricing.

Buwon was originally founded in 1993 as the Merck Balzers Optoelectronics Advanced Coating Division (later SNPtaiwan), renamed Fuyuan Precision Coating in 2009, and rebranded to its current name. It conducted its IPO on Taiwan's OTC market in December 2010 and registered on the emerging stock market (興櫃) in January 2011, with JAFCO Asia as a second-largest institutional shareholder. Revenue exceeded NT$1 billion in 2008; no later revenue figure is disclosed in the available data.
