Samsung has unveiled an even larger version of its modular micro LED display "The Wall" at the Integrated Systems Europe 2020 AV exhibition. It now measures a full 583" (18.8 meters) diagonal screen size with a resolution of 8K UltraHD (7680 × 4320 pixels) and nicely demonstrates the progress Samsung is making in combining micro-LED components: the first version in January 2018 was 146 inches in size, followed a year later by 
at CES 2019 with a 75" 4K TV and a 219" (5.19m) model, and in autumn a 292" (7.41m) version.
The latest model has a brightness of up to 2,000 nits at a ratio of 10,000:1 and a refresh rate of 120 Hz. The giant display is intended for very special applications such as in control rooms or lobbies - the (as yet undisclosed) price will be accordingly high.
However, Samsung still lags slightly behind Sony, who installed already in April 2019 a 19.2 x 5.4m micro-LED display with a resolution of 16K in 32:9 format in the new research centre of the cosmetics company Shiseido in Yokohama.
Micro LEDs have the advantages of OLEDs without their disadvantages such as burn-in effects and decreasing brightness over time and thus a relatively short lifetime. Another feature of micro LED technology - namely the absence of a screen border/ bezel - allows Samsung to assemble displays from multiple, freely configurable micro LED modules, so that additional modules can easily be added to increase the display area.
