LG's got a transparent OLED display, and if you're wondering how such a device could be useful, the company has a few ideas to share.

Ahead of the upcoming CES 2021 show, LG shared a few ideas on how its transparent OLED products could fit into real-world situations.

One idea is having a transparent OLED at a restaurant, where the display would pop up from the bar, between the customer and the waiter, allowing the customer to see the menu and order while still being able to see the waiter.

LG also designed a Smart Bed with a frame from which a transparent OLED TV can rise up, and retract to when not needed. The frame, which also features a set of speakers, can freely be moved around the house.

Another example is having a 55-inch transparent OLED display at a subway train, where it replaces a traditional window. The customers could enjoy the scenery while viewing the weather forecast, the news, and information on subway lines.

LG says its transparent OLED displays have a 40 percent transparency, which is a lot better than transparent LCDs which only have a 10 percent transparency. This makes such TVs useful in a wider number of scenarios, including autonomous cars, aircraft, and smart buildings, to name a few.

We'll learn more about LG's transparent OLED displays when the CES 2021 kicks off on Jan. 11.
