Flat-Panel Display Modules: Uneven Scale Across LCD and OLED
Executive summary
This category covers flat-panel display modules, including LCD and OLED, with or without integrated touch sensors. The market divides into two technology groups and has large differences in company scale. BOE reports production sites in ten Chinese cities and says it has led LCD panel shipments across multiple applications for several consecutive years. LG Display reports a more concentrated footprint in Korea and Guangzhou, and an approximately 13% share of displays larger than nine inches in 2025 based on Omdia data.
BACI 2024 trade data show exports of about $108.8 billion and an exporter HHI of 2,385. China accounts for 36.6%, Vietnam 25.9%, South Korea 16.0%, Other Asia, nes 8.1%, and Hong Kong 7.2%. These locations can reflect final assembly and re-export; they do not directly measure where display technology or panel capacity is controlled.
Inputs and downstream uses
Himax and Samsung Electronics disclosures support display-driver ICs as inputs to modules. LG Display reports 2025 revenue shares of 35.4% for mobile and other products, 18.6% for TVs, and 36.8% for IT products such as notebooks, desktop monitors, and tablets. Samsung describes mobile OLED panels for smartphones and also sources panels for TVs and monitors from outside manufacturers including CSOT and SDP.
The report adds supported module links to smartphones, TVs/monitors, and computers. OLED emitting materials, glass substrates, and touch sensors have company-level relationship evidence from Universal Display, Corning, and TPK, but their exact trade-classification correspondence is not established. Automotive supply has limited support from LG Display's sales mix, while the downstream classification mapping remains uncertain; these links were not added to the physical graph.
Network audit and limitations
The current category is display modules, not recording media; older hypotheses based on disks, tapes, or semiconductor storage were removed after confirming the classification scope. Recycling evidence is limited to regulatory frameworks; actual recovery quantities and separation processes were not established. Evidence for AU Optronics, Innolux, Japan Display, and polarizers was incomplete in the cited research.
