Recently, K-Display 2025, the Korea Display Industry Exhibition, was held in Seoul, where Samsung Display showcased the world's brightest Micro LED smartwatch screen.
At CES 2025 earlier this year, Samsung Display first showcased a Micro LED wearable display with a peak brightness of 4,000 nits, brighter than Apple Watch's 3,000-nit OLED. After seven months of improvements to luminous efficiency, the screen's brightness has increased to 6,000 nits, with a resolution of 326 PPI, and contains approximately 700,000 micro tri-color LED chips.
Micro LED has significant advantages in wearable devices, primarily in its high brightness and high efficiency. Samsung Display has been developing Micro LED wearable screens since 2023, with Samsung Electronics planning to launch the first related product by the end of 2025.

It's worth noting that several companies, including AU Optronics (AUO), are also developing wearable Micro LED displays, with AUO already in commercial production. Although Apple cancelled its major project in early 2024, it continues to advance the technology. Garmin and luxury brand TAG Heuer are also developing their first Micro LED smartwatches, both using AUO technology.
In the Micro OLED field, Samsung showcased several high-end products, including a 1.3-inch W-OLED dual-lens display with 4000 PPI and 1000 nits brightness; a 1.4-inch RGB OLED with 5000 PPI; and a 1.3-inch RGB OLED with 4200 PPI and 20000 nits brightness using MLA technology.
