Corning Wins Critical ITC Ruling Over IRICO in Display Glass Dispute

This ruling significantly strengthens Corning's ability to protect its fusion-draw process, the foundational technology for high-precision LCD glass. By shifting the legal focus from specific glass formulas to the underlying manufacturing 'know-how,' Corning can potentially block a wider range of IRICO-produced materials and downstream consumer electronics. For the global display ecosystem, this reinforces the dominance of established IP holders at a time when Chinese domestic producers are aggressively scaling high-generation (Gen 8.5+) production capacity. The immediate impact targets IRICO's supply chain, but the broader signal warns panel makers like BOE and TCL against integrating contested components. Watch for the ITC's final determination scheduled for November 2026, which will dictate the enforcement of the recommended import bans.

The display glass industry remains a high-barrier oligopoly, with Corning, AGC, and Nippon Electric Glass (NEG) controlling over 80% of global market revenue as of early 2026. Per market reports from DataIntelo and Grand View Research, the sector was valued at approximately $14.6 billion in 2025, driven by surging demand for large-format Gen 10.5 layouts and automotive multi-screen cockpits. While Corning maintains the lead, Chinese state-backed firms like IRICO and Dongxu Optoelectronic have recently increased their domestic market share to roughly 17% in a strategic effort to localize supply chains for panel giants like BOE and TCL CSOT.

Corning’s aggressive litigation strategy has already forced several major respondents into settlements. Per ip fray reporting in April 2026, Hisense, VIZIO, and LG reached confidential agreements with Corning to resolve related patent disputes earlier in the year. Meanwhile, IRICO faces significant internal financial pressure. According to recent analyst briefings, IRICO Display forecast a 75% profit decline in early 2026 due to contracting margins in its legacy LCD TV panel business. To counter this, the company announced a $282 million investment in July 2026 to raise its stake in Hongyang Display, the entity responsible for constructing its 8.5-generation substrate glass lines. This expansion into higher-margin segments now faces a direct threat from the ITC’s recommended exclusion orders.
