Micro LED is Samsung's most feared OLED killer

Micro LED refers to light-emitting diodes with a size smaller than 100 microns—roughly the diameter of a human hair. Unlike traditional LEDs, which are typically used in lighting applications, Micro LEDs are designed for display technology. They are manufactured by transferring the tiny chips directly onto a substrate, eliminating the need for the original growth substrate. This advanced process allows for more consistent color output and higher brightness, making them ideal for high-quality displays. This innovation has caught the attention of major players in the industry, including Taiwan’s LED manufacturers, who are looking to break away from the saturated and highly competitive traditional LED market. With their potential to deliver superior image quality, Micro LEDs are seen as a promising next-generation display technology. In comparison to traditional LCD screens, which rely on a large backlight panel to illuminate the liquid crystal display, both OLED and Micro LED technologies are self-luminous. This means they can emit light directly without the need for a separate backlight, resulting in better energy efficiency and a simpler design. Additionally, since OLED and Micro LED can communicate through similar circuitry, companies like Apple have been exploring both technologies simultaneously, aiming to find the best solution for future devices. Despite these advantages, Micro LED holds a clear edge over OLED. OLEDs use organic materials that are sensitive to moisture and tend to degrade over time, leading to lower yields and reliability issues. In contrast, Micro LEDs are inorganic, making them more stable and durable. Moreover, they offer significantly higher luminous efficiency—about three times that of OLED—and a broader color gamut. As a result, many experts believe that Micro LED is well-positioned to enter mass production, particularly for large-screen displays, and could eventually challenge OLED in the premium display market.
