May 21 2025 – Today, tech media outlet patentlyapple unveiled a blog post highlighting Dowinsys’ unveiling of an innovative “Hybrid Ultra-Thin Glass” (Hybrid UTG) technology. The company has outlined plans to finalize product application testing by 2025 and commence mass production in 2026.
According to the blog post, this cutting-edge technology involves etching only the central portion of the glass. By adopting a design that thins the folding area while thickening the flat regions, it ensures flexibility in the foldable section while boosting impact resistance in the flat areas.
The report underscores that the technology achieves a bending effect with a curvature radius of less than 1R, coupled with a processing precision that maintains a 40-micron (μm) difference in thickness. This development is hailed as a significant breakthrough in the realm of foldable devices.
The blog further notes that, currently, UTG products featuring only central etching have not yet entered mass production in the market. However, Apple has shown keen interest in this technology, with sources indicating that Dowinsys is actively vying for a spot in Apple’s UTG supply chain for foldable devices.
Dowinsys emphasizes its capability to independently handle both the pre-processing (such as thinning) and post-processing (such as strengthening) stages of UTG production, positioning itself as the sole UTG enterprise in South Korea with comprehensive process capabilities.
Additionally, Dowinsys has disclosed that it has successfully developed an 18.1-inch large-area UTG and is ready for delivery. This development is speculated to align with Samsung Electronics’ plans to launch a foldable tablet and laptop in early 2026. It is anticipated that the device will function as an 18.1-inch laptop when unfolded and transform into a roughly 9-inch tablet upon folding.
