Transparent OLED: See-through TV comes to tomorrow’s beds, restaurants, subways

Clipping /

LG says demand for transparent screens is increasing in smart homes and buildings as well as driverless cars, aircraft and subways. Among the three scenarios in the 2021 virtual showroom the “smart bed” seems the least useful to me, but it’s easy to imagine a future where such displays are so cheap and ubiquitous that video or information can appear on any normally transparent surface, from windows to glass coffee tables to eyeglasses. It’s not as mind-blowing as a roll-up TV, but it’s arguably more practical.
