At the ongoing International Consumer Electronics Show 2025 (CES 2025), Samsung showed off a new Micro LED screen designed specifically for smart watches. The prototype screen has extremely high brightness, which is especially suitable for outdoor use and is expected to be used in smartwatches such as the next Galaxy Watch Ultra.
The Micro LED has a 2.1-inch screen with a resolution of 418 x 540 pixels and a pixel density of 326ppi. What’s more, its peak brightness is up to 4,000 nits, which is 33% brighter than the Galaxy Watch Ultra’s OLED screen. Previously, the Galaxy Watch Ultra was known for its excellent Super AMOLED screen with a peak brightness of 3,000 nits.
According to Igeekphone, Micro leds are theoretically more durable and last longer than OLED screens, while retaining the existing advantages of OLED screens. Like OLED screens, Micro LED screens also have self-luminous characteristics, providing pure black color, unlimited contrast and wide viewing angles. In addition, Micro LED screens have faster response, higher energy efficiency, and can operate over a wider temperature range, reducing the risk of thermal damage. These features and advantages make the Micro LED screen ideal for smartwatches.
In the past, the pixel density of Micro LED screens was not as good as that of OLED screens, but the Micro LED screen displayed by Samsung Display this time has overcome this problem and its pixel density is comparable to the OLED screen used by the existing Galaxy Watch.
At present, no other smartwatch in the world uses a Micro LED screen. Apple has reportedly experimented with Micro LED screen technology, but has not yet applied it to the Apple Watch, and it is reported that Apple has abandoned plans to apply Micro LED screens to its smartwatch.
Samsung has always been known for adopting advanced and breakthrough display technology in its devices, and the debut of the Micro LED screen undoubtedly provides an excellent upgrade opportunity for the second generation Galaxy Watch Ultra.
