    The dream of clamshell phones - once a science-fiction movie fantasy - may have come true, but these types of smartphones have two major problems; The first is that their folding screens are wrinkled at the hinge, and the second is that the plastic layer on these screens is usually weaker than glass screens. But apparently a solution has been found to these problems. LG Chemical Chemical Company (LG Chem) recently unveiled a new technology for making folding screens in a news release on its main website. According to LG Chemical, the display layer of this display is made of materials that are hard glass, but plastic flexibility.

    LG Chemical has chosen the name Real Folding Window (real folding window) for this new panel. The coating material in this new technology is stretched on both sides of a plastic sheet called PET. Abbreviated PET is Polyethylene Terephthalate and is actually the same plastic used to make some soft drink bottles. According to LG Chemical, after applying only a few microns of this coating on both sides of the PET layer, it can be used as a cover in the construction of flexible OLED panels. In this way, we will have a folding display that will be more resistant to heat while being more durable and less thick.

    Another positive point of this display is that no hinges appear on the hinge. According to LG Chemical, the display continues to operate even after folding 200,000 times, significantly reducing the lines caused by the fold (which can be seen in the screens of today's clamshell phones). Another positive point is that this display, in addition to being folded from the inside (in-fold), will also have the ability to be folded from the outside (out-fold). According to LG Chemical, the display also competes with current foldable screens in terms of cost.

    Apparently, the Real Folding Window panel, in addition to making clamshell phones, can also be used in the production of tablets, laptops and roll-up phones. According to the LG Chemical website, the company is also developing newer technology that allows the Real Folding Window panel to be produced without the need for a PET layer. Due to the removal of the PET layer, this panel is usually thinner than the previous panel and in addition to clamshell phones, it will also be efficient in making rollable devices.

    You have to be a little patient to get devices with the new Real Folding Window display. LG Chemical noted that it will be able to mass-produce these panels in 2022, and products equipped with these displays will enter the market at least from 2023. Of course, in this news, LG Chemical only mentions the nature of the folding and flexibility of this new panel. Therefore, until we get a product equipped with this technology, we can not judge the difference between this panel and glass in other ways (including transparency).

    Finally, it should be noted that Samsung is also on fire in the production of displays using PET. The Korean company has used a layer called PET stretch to cover the display cover (which it calls ultra-thin glass) on Galaxy Z Flip3 and Z Fold3 displays, which experts say is a comparison to previous-generation folding screens. These phones have been much better. Samsung is also reportedly making clamshell displays for other smartphone makers (including Google). It is also said that Corning (manufacturer of Gorilla Glass resistant glass) intends to cooperate with Samsung in the production of folding glass to compete with Schott.
