Corning's price increase warns China's display industry: although panel capacity ranks first globally, pricing power over glass substrates remains in others' hands, making industry security urgent.
On September 11, a price increase notice from the American company Corning landed like a stone tossed into a calm lake, instantly stirring up wave after wave of disruption across the global advanced display industry.
Corning announced that, under the dual pressures of exchange rate fluctuations and inflation, the company will implement a price increase of 15% or more worldwide on display glass substrate products denominated in Japanese yen. The specific increase will be executed on a differentiated basis according to product category, generation size, and cost impact, and will officially take effect in the fourth quarter of 2026.
Before the echo of those words had faded, leading domestic panel manufacturers such as TCL CSOT, BOE, and HKC successively sent price increase letters to downstream customers, passing the upstream cost pressure down link by link.
It is worth noting that this is already Corning's third price increase in the display glass substrate field since 2023.
This round of chain-reaction price increases has struck like a heavy hammer on the long-concealed soft spot in China's advanced display industry chain: we produce more than 70% of the world's panels and hold the production capacity advantage in end-screen manufacturing, yet the pricing power over that piece of "industrial foundation" that supports the entire screen remains firmly grasped in the hands of a small number of overseas enterprises.
What is a glass substrate? It is the most basic and also the most core underlying material of LCD panels. Without this kind of ultra-thin, ultra-high-flatness specialty glass, even the most advanced panel production line can only find itself unable to cook a meal without rice. The global high-generation glass substrate market has long been dominated by the three giants Corning of the United States, AGC of Japan, and Nippon Electric Glass. Corning alone has a market share of more than 50%, and its advantage is even more prominent in the field of high-generation large-size substrates. The core process of the overflow fusion method, exclusive formulations, and a complete patent system together build a technological wall that is difficult to surmount.
This kind of monopoly is far more than simply "the product sells well"; it is control over the discourse power of an entire ecosystem.
Panel factories often require investments of tens of billions to build, and once a production line is ignited, it absolutely cannot be stopped at will. Production line design, process debugging, and yield optimization all require long-term supporting coordination with upstream substrate suppliers. When there are only a few options for core substrates, once the other party raises prices, downstream enterprises have almost no choice: they can neither easily switch to domestic suppliers nor dare to bear the huge risks of yield decline and production line shutdown.
This is an invisible shackle on the industrial chain: even if downstream panel production capacity ranks first in the world, when upstream key materials are firmly locked in, the industry will always remain in a position of passively bearing pressure.
In recent years, the comeback of China's panel industry has been obvious to all. From the early years when "even a single screen had to be imported at a high price" to today when BOE and TCL CSOT have proudly advanced into the global first tier, the domestic advanced display industry has grown into a strategic pillar industry worth hundreds of billions, and mobile phone screens, TV screens, and automotive screens are being supplied to the world in large quantities. Yet behind the prosperous panel production capacity, the structural contradiction of "strong terminals, weak materials" has always followed like a shadow. As an upstream core material, glass substrates, although good news of domestic breakthroughs continues to arrive, are still in a stage of climbing over hurdles in the tough battles of high generation, large-volume production, stable yield, and long-term verification and supporting coordination, and have not yet formed a substitution ecosystem capable of confronting overseas giants head-on.
This round of price increases has taught us an extremely realistic lesson in industrial security. Rising costs are merely a surface excuse; the deeper risk lies in the fact that when the supply of key materials is highly concentrated, overseas giants can use pricing power to periodically adjust prices and continuously squeeze the profit space of domestic panel enterprises. Once the geopolitical environment changes abruptly, they may also directly impact the stable operation of the entire domestic advanced display production line through measures such as restricting supply and patent litigation.
Industrial security has never been an empty slogan; it is hidden in every raw material procurement contract and in every round of confrontation and bargaining in price negotiations. To escape the situation of being passively beaten, it cannot rely only on enterprises fighting alone. It requires "effective markets and a proactive government working in concert," accelerating the improvement of top-level design for the advanced display industry and systematically advancing domestic substitution.
What is a proactive government? It means rising above the mindset of supporting a single enterprise and making coordinated arrangements from the height of the security of the entire industrial chain. On the one hand, it should continue to increase investment in basic research and industrialization tackling of bottleneck links such as glass substrates, core lithography materials, and precision equipment, make good use of mechanisms such as the "open competition mechanism to select the best candidates" and industrial funds, and support domestic material enterprises in settling down to gnaw through the hard bone of long-term high-cost yield climbing. On the other hand, it should improve the standards system, intellectual property protection, and antitrust supervision, maintain a fair trading environment in the industrial chain, and strictly prevent upstream material giants from abusing their market dominance. At the same time, it should open up verification channels for domestic materials, promote panel enterprises to prioritize pilot use of local materials, and effectively resolve the application bottlenecks of "having products but not daring to use them, and wanting to use them but having no opportunity."
What is an effective market? It means giving play to the market's screening role and using end demand to drive upstream innovation. Panel manufacturers, material enterprises, and terminal brands should be encouraged to form industrial chain consortia, establish long-term coordinated supply and demand mechanisms, and form a complete closed loop of material research and development, production line verification, and bulk procurement. Stable orders should be used to feed back into upstream material enterprises, helping domestic substrate manufacturers polish their processes through continuous iteration, continuously expand market share, and gradually form a diversified supply pattern, thoroughly breaking dependence on a single source.
Advanced display is not just the screen of televisions and mobile phones; it is also the core hardware of automotive cockpits, AR/VR, industrial displays, intelligent equipment, and military products, and it is the underlying infrastructure of the digital economy and intelligent manufacturing. Making panel production capacity larger is only the first step. Only by firmly rooting the foundation of the industrial chain and firmly grasping the supply and pricing power of core materials in our own hands can industrial security truly take root.
This round of surging price increases is both a crisis and an opportunity. The story of China's "screen" cannot forever remain停留在 a victory on the manufacturing side. Only with government and enterprises working with one heart and the entire chain coordinating, continuing to tackle core materials, and building an independent, controllable, safe, and resilient industrial ecosystem, can our advanced display industry truly grasp the initiative in development and calmly respond to every storm in the global supply chain.
