The TV uses OLED technology and can be viewed at a range of angles. It can be rolled down to different degrees so that only a sliver of screen is visible or completely hidden within the base unit.

It also uses LG’s AI system to provide the best picture and sound quality, as determined by its machine learning-capable processor.

The Korean tech giant also announced Airplay 2 support for its 2019 TV line up, following similar announcements from Sony and Samsung who have also adopted Apple’s wireless video standard.

LG said its rollable screen is a “home entertainment marvel” and something which only “science fiction directors” had previously imagined.

It has been developing it as a prototype for some time, but this official unveiling indicates that the company is planning to make it available to consumers, although LG has yet to confirm when the device might go on sale or how much it will cost.

LG’s David Vanderwaal said: “LG’s rollable OLED TV goes beyond what a TV could traditionally offer. It brings the freedom of design to the space, without the limitations of a wall. This offers a never-before achieved level of immersion.”

LG also showed off its “HomeBrew” beer system which uses pods containing yeast, hop oil and flavouring and an “optimised fermentation algorithm” in an autonomous device to create up to five litres of beer in around two weeks.

Elsewhere at CES 2019, Samsung unveiled a range of assistive robots and new smart appliances, such as its Family Hub smart fridge, which features virtual assistant Bixby allowing users to control other smart appliances around the home, including speakers and robot vacuum cleaners.

It will be possible to answer queries about news and weather, as well as find recipes and even order an Uber taxi from the fridge’s built-in screen, Samsung said.

The firm’s new assistance robots are designed to help in home, retail and medical care situations.

Bot Care is able to track vital signs using a built-in fingerprint scanner; Bot Air is used inside a house to monitor air quality, while the Samsung Gems [sic] is a wearable device designed to aid movement and walking for people with mobility issues.

Samsung also said that it will release its first phone ready for 5G mobile connectivity this year – a key area of innovation for many tech giants.

Samsung consumer electronics president HS Kim said: “2019 is Samsung Electronics’ 50^th anniversary and for the last five decades we’ve been committed to bringing meaningful innovations to consumers everywhere.

“In 2019, we’re taking things to the next level and leveraging our industry leadership to make our vision of connected living a reality.”

Also among the announcements was a connected driving solution called the Digital Cockpit, which Samsung said would enable drivers to remotely check settings in their car before they get into the vehicle, as well as control aspects of their smart home from inside the car.

It, too, will be powered by the Bixby virtual assistant, which has been the subject of focused development by Samsung in order to make it a compelling voice-assistant rival for the more established likes of Amazon’s Alexa, the Google Assistant and Apple’s Siri.
