Yesterday Patently Apple posted a report titled "Samsung's Rumored Folding Phone is to Generate Buzz for their Developer Conference in November." Today the news is that Samsung SDI has recently succeeded in developing the world's first optically clear adhesives for foldable panels that are expected to be used first for Samsung Electronics' upcoming foldable smartphone.
OCA tapes are used to bond panels, mobile devices and touch screen displays. They are considered essential in adding superior strength and durability while improving optical clarity and picture quality. Samsung SDI is the first to mass-produce the tapes for foldable phones.
Sources say Samsung SDI, the battery-making unit of Samsung Group, started developing the tapes four to five years ago and the firm has recently been selected as the material supplier for Samsung outpacing the potent rival and industry leader 3M.
An insider told the Korea press that "Samsung SDI will be the sole supplier of OCA tapes for Samsung. 3M may have to wait until Samsung diversifies suppliers after the phone launch."
Samsung is highly likely to unveil its first foldable phone in November as the first smartphone maker to do so. Upon the phone's pending debut, Samsung SDI is also expected to win the official "world's first" title.
The initial shipment of the Samsung phone is estimated to reach some 100,000 units per month. The Korean tech giant plans to expand production after gauging the market reaction.
