The Samsung Galaxy Z Flip is the world’s first flexible device with ultra-thin glass (UTG) covering the display. Actually, it remains the only such device, because other companies have not yet mastered the production of such glass.
Sources claim that Samsung Display has decided to start supplying UTG glass to third parties. Google may be the first buyer, in which case we should expect a flexible Pixel or some other device with a similar display.
The reason Samsung has decided to sell UTG glass to third parties is because the Korean giant wants to ramp up its supply of flexible displays. The company could add ultra-thin glass to its offering while raising its price.
