Sidike (斯迪克) began supplying optical adhesive and anti-reflective films for selected domestic foldable-phone models.

Sidike (斯迪克) stated on an investor-interaction platform on September 7 that it had begun supplying materials for selected domestic foldable-screen terminal models. The disclosure covers only some models and does not identify the device manufacturers.

The supplied products are optically clear adhesive, or OCA (OCA 光学胶), and anti-reflective film, or AR film (AR 减反膜). These are component materials used in display assemblies rather than complete foldable displays or finished phones.

The source confirms that supply has commenced but gives no shipment volumes, contract values, customer concentration or revenue contribution. It also does not specify whether the supply agreements are exclusive or how many models are covered.

A separate source reported that Huawei, Xiaomi and Apple were scheduled to introduce foldable flagship phones within a 72-hour period from September 7 to early September 10. That report did not identify Sidike as a supplier to any of those specific devices.
