BOE Expands into Wafer Fabs and Glass Substrates, Squeezing South Korea's Chip Industry
nashnova research
BOE is simultaneously advancing glass-substrate pilot production and a 12-inch wafer fab, extending its display dominance into chip manufacturing — a vertical-integration push that puts dual pressure on Korea's chip and panel industries.
How far along is the glass substrate line?
BOE announced on June 12 that its glass-substrate pilot line has completed full-process automated equipment integration, with a designed monthly capacity of 1,000 wafers.
The company has produced a 20-layer (9-2-9 structure) large-format glass-substrate sample and shipped it to select Chinese customers — some have finished proof-of-concept and moved into technical testing. This means → the product has passed the "can it be made" stage and is now proving "can it be used."
The timeline spans six years: research started in 2020 → RMB 390 million invested in a lab in 2022 → RMB 993 million added for the pilot line in 2024 → major equipment installed by 2025.
What will the 12-inch wafer fab produce?
Through its wholly owned subsidiary Tianjin BOE Innovation Investment, BOE is building a 12-inch wafer fab in Beijing. Total investment: RMB 33 billion. Core equipment was installed by December 2025; volume production is planned for H2 2026.
The fab will make display driver ICs (DDI), power management ICs (PMIC), and automotive-grade microcontrollers (MCU) — all feeding BOE's own latest panels. In plain terms = BOE wants to replace "buy someone else's chips for our screens" with "our chips, our screens" — full vertical integration from panel to silicon.
This reflects a broader shift: after the U.S. tightened restrictions on Chinese firms using offshore foundries like TSMC, building in-house fabs became a strategic necessity for panel makers.
Is BOE the only one doing this?
Far from it. TCL CSOT acquired compound-semiconductor manufacturer Fujian Zhaoguang in March 2026. Zhaoguang can mass-produce Mini LED and Micro LED chips using gallium nitride (GaN) — a compound material suited to LED fabrication.
Visionox is doubling down on glass substrates, committing RMB 5 billion to a project in Jiangsu province and bulk-purchasing optical and X-ray inspection equipment in April 2026 to raise pilot-line yields.
This means → China's panel industry is collectively extending into the chip layer — not a one-company impulse, but an industry-wide strategic pivot.
What pressure does Korea face?
Industry analysts note that Chinese panel makers' chip-integration push is rapidly closing the technology gap with Korea in display drivers and OLED.
Korean industry figures argue the country must accelerate investment in next-generation technologies to hold its competitive edge. In plain terms = Korea's generational lead in the chip layer is now being eroded in reverse — from the panel side.
The critical test: whether Chinese panel makers can hit volume production on schedule. That will determine if the competitive landscape is genuinely reshaped or remains at the planning stage.
