Samsung unveiled its first Micro-LED TV at CES, aptly named "The Wall". This is a 146-inch tiled 4K display that is almost 8 times larger than a 55" TV in area. We don't have any technical details yet on this display, but according to reporters at CES you cannot see the seams of the individual tiles.
Samsung says that this display will ship in 2018 - but it did not reveal the price or expected release date. It's also not clear whether you will be able to actually customize this display with smaller and/or larger sizes.
Samsung is looking for a new premium TV technology as its QLED TVs failed to keep up with LGD's OLED TVs, and has seen its premium TV market share fall from 57% in 2015 to 20% in 2016 (LG, meanwhile, managed to increase its market share from 17.5% in 2015 to 43% in 2016). Samsung is said to be looking at several alternatives for its micro-LED TV project, one of which is to acquire Taiwan-based PlayNitride - a deal that was already reported in April 2017 but is reportedly progressing.
It will be very interesting to see how Samsung's Micro-LED TVs fares against competing technologies, and will hopefully kickstart the Micro-LED industry. Back in 2012, Sony demonstrated the world's first Micro-LED TV, the 55" FHD Crystal-LED panel. Sony never released this product commercially (although it does offer Micro-LED large outdoor signage displays).
