Korean display makers step up OLED patent push as China narrows technology gap
Korean display makers are stepping up patent licensing and cross-border enforcement as Chinese rivals have sharply narrowed the technology and market-share gap in OLED since 2020, just as competition expands into higher-value panels for notebooks and monitors.
Asia Optical delivered strong second-quarter financial results while accelerating its strategic expansion across optical technologies. Key growth drivers include Metalens and Co-Packaged Optics (CPO), with digital camera shipments confirmed to top 4 million units in 2026.
ams OSRAM said it filed two patent infringement lawsuits in Germany against Shenzhen Refond Optoelectronics over automotive LED products. The move adds to a broader wave of intellectual property disputes in the LED sector and targets ceramic-packaged and EMC-packaged vehicle lighting products sold by the Chinese supplier.
Daxin Materials is expanding its semiconductor footprint, with semiconductor materials accounting for nearly 23% of revenue in the second quarter of 2026. The company expects the segment to reach 25% to 26% of full-year revenue, driven by 12 products already in mass production and a further 14 under customer validation.
LED packaging manufacturer Everlight Electronics stated that due to higher raw material costs, gross margin fell to 24.16% in the second quarter of 2026, down 7.93pp year-over-year and 0.5pp from the first quarter, mainly due to fluctuations in the Chinese yuan exchange rate.

MicroLED remains a promising next-generation display technology, but industry analysts say its commercial breakthrough still hinges on thin-film transistor (TFT) technology and the participation of South Korean panel makers Samsung Display (SDC) and LG Display (LGD). Yet SDC is reportedly taking a cautious stance on microLED TV applications.

Driven by a recovery across smartphone, notebook, industrial control, and automotive applications, ITH Corporation, the parent company of Ili Technology (Ilitek), posted solid revenue results in the second quarter of 2026. However, its gross margin took a hit of about 8.1 percentage points after it recognized a one-time liability provision because wafer starts fell short of volumes reserved under an agreement with a supplier.

E Ink has lowered its 2026 revenue growth outlook after rising memory prices hit demand for consumer electronics, but the company said IoT and e-paper signage businesses remain strong. Full-year revenue growth is now expected at 10-15%, down from an earlier forecast of 20-25%, while consumer electronics revenue could fall by double digits.

With global TV demand slowing and panel prices continuing to fall, display makers are facing intensifying profit pressure. Analysts say the industry's bottleneck extends beyond low-priced Chinese competition and reflects a broader reshaping of the consumer electronics value chain, with OLED's next growth phase likely to depend on lower manufacturing costs and wider adoption in IT devices.

Seoul Semiconductor and its affiliate, Seoul Viosys, have secured a permanent injunction from India's Delhi High Court against Ornate Agencies Private Limited, barring the Indian company from selling products that infringe Seoul Semiconductor's opto-semiconductor patents. The court separately enjoined Ornate's managing director from further involvement in the infringement, according to a joint statement from the two Korean companies issued on August 12, 2026.

Qisda Chairman Peter Chen said infrastructure is the foundation that must first be built as AI compute demand surges. He said Qisda will not be absent from the fast-growing race, as the company steps up work on AI servers, data centers, 1.6T switches, and silicon photonics (SiPh).

Foxconn said its decade-long partnership with Sharp has entered a new growth phase, as the Taiwanese electronics group expands into AI servers, semiconductors, robotics, and next-generation communications. The comments, made at Foxconn's second quarter 2026 investor conference on August 12, came as the two companies marked 10 years since Foxconn completed its investment in Sharp.
