The hospitality display paradigm changed in January 2018, when Samsung unveiled “The Wall,” the world’s first modular MicroLED 146-inch TV at CES in Las Vegas.
The modular, self-emitting MicroLED 146” TV display was featured alongside Samsung’s latest innovations in display technology, demonstrating how display technology is evolving to offer a truly outstanding viewing experience.
The effect of this event, seen by many pundits as the most impactful advance in display technology in recent years, has been to turn the industry’s attention to LED.
MicroLED’s pixel pitch (the diameter of each individual pixel) is 0.8mm, almost half that of the current smallest pitch of 1.5mm. The display demonstrated at CES was made using 3840×2160 liquid crystals that all generate their own light and colour. No longer does the light come from external backlighting that has to be shared across multiple pixels (often tens of thousands at a time), or even across all the pixels at once.
This means that Samsung’s LED is able to place incredibly bright pixels right alongside basically black ones without any light bleed between the two. OLED technology can already do that, of course, but the advantage of The Wall is seeing this feature joined with the massive amounts of brightness nonorganic pixels can push out that current organic LED (OLED) pixels cannot. The two biggest advantages Micro LED will have over OLED will be lifespan and customisation. OLED’s big drawback has been “burn-in”. Because OLED uses organic material, the performance of the pixels declines more rapidly over time. LED on the other hand, uses inorganic material that lasts many times longer. Micro LED also makes it easier for Samsung to make displays bigger or smaller. OLED is made from a set substrate size that can’t be altered.
The MicroLED technology featured in The Wall eliminates the need for colour filters or backlight, yet allows the screen to offer consumers the ultimate viewing experience. Also, the MicroLED screen excels in durability and effectiveness, including luminous efficiency, the light source lifetime and power consumption, setting the standard for future screen technology.
Featuring a module-based, bezel-less design, “The Wall” also exemplifies how consumers can customise their television sizes and shapes to suit their needs. The screen can adapt to serve different purposes, such as creating a wall-size display for multiple spaces. This concept can be easily transposed to the hospitality environment, in lobbies, suites, sports bars, or other common areas.
