Samsung collaborates with Dolnsys to produce ultra-thin bendable glass

News unit After the delay in the supply of Samsung Galaxy Fold, doubts about the resistance of the screen This phone was born. But finally, after making some modifications, the company introduced its first bendable phone in the market in September, which also met with good sales. But recently, there were rumors that Samsung intends It is using real tempered glass instead of plastic covers in making bendable phones. You might be saying to yourself, glass can’t bend. But ultra-thin and ultra-durable glasses have this ability. In this context, Samsung announced the signing of a long-term and exclusive contract with a Korean company called Dolnsys.

In the Galaxy Fold smartphone, a flexible layer of polyamide (PI) is placed on the screen. This layer is prone to scratches and is not as beautiful as glass. To be more precise, this layer is a part of the phone screen itself and is not just a screen protector, so if someone tries to remove this layer, it will seriously damage the screen. For this reason, in the new corrected version of the Galaxy Fold, Samsung continued it to the bottom of the phone frame, which caused the Galaxy Fold to be delayed. It should be noted that this polyamide layer is a product of the Japanese company “Sumitomo” and due to the ongoing trade disputes between Korea and Japan, its export to Korea has faced severe restrictions. Considering that this polyimide layer is considered an integral part of the Galaxy Fold display, the production of this particular phone without it faces a major problem.

for To solve this problem Samsung decided to use the polyimide layer with glass replace In the meantime, Samsung has chosen the Korean company Dolnsys and by signing an exclusive contract, it has acquired all the products of this company. This company – which was established in 2010 – produces ultra-thin tempered glass (known as UTG) and currently continues to work with a production capacity of about 500 thousand glass units per month; Glass that can bend without breaking. According to this contract, Samsung has committed to invest 12 billion won in this company. According to some sources, this investment will increase in the future so that Dolnsys can increase its production capacity by expanding its facilities in Korea and building new factories in Vietnam.

Currently, mass production of ultra-thin glass has been started by Dolnsys. These glasses have a thickness of less than 100 microns, and according to some reports, Dolnsys technology is so advanced that it can reach 30 microns (that is, less than the thickness of a human hair). In this way, Samsung can abandon the polyimide layer in the production of a bendable smartphone and use this glass to significantly improve the durability of the phone. It should be noted that the folding screen is the most expensive part of a bendable smartphone, and due to the exclusiveness of Dolnsys products for Samsung, this company can use ultra-thin glass in the production of its other products (such as laptops, tablets, etc.). Needless to say, by signing this contract, Samsung has kept itself ahead of Chinese companies engaged in this field.

According to some experts, Samsung will introduce 5 to 6 million bendable smartphones in the next year. Most likely, the Galaxy Fold 2 – which is expected to hit the market in the spring – will use Dolnsys ultra-thin glass.
