Samsung Display announced on the 27th that it will showcase next-generation mobile organic light-emitting diodes (OLED) with a brightness of up to 5,000 nits at the world's largest mobile communication exhibition, the Mobile World Congress (MWC 2025), which opens on March 3 in Barcelona, Spain.
The ultra-bright OLED displayed by Samsung Display this time is clearly visible even outdoors and is about 1.5 times brighter than the latest premium smartphone OLED with the same power consumption. The world's first commercialized "no" polarizer display was developed based on "OCF (On-Cell Film)" technology. OCF, which serves as a foundation for improved outdoor visibility, reduced power consumption, and design innovation, is being expanded to include regular bar-type smartphones and rollable laptops following foldable smartphones.
The polarizer, an opaque plastic sheet made of metal and glass, is a component that prevents the display from reflecting external light like a mirror, which decreases visibility. However, the light emitted by the pixels loses more than 50% of its brightness as it passes through the polarizer, ultimately reducing the display's luminous efficiency.
Another advantage of OCF technology is that it eliminates the polarizer, making the panel thinner. Panels with OCF technology are about 20% thinner compared to existing OLED panels with a polarizer. A thinner panel inherently has lower rebound strength, which is advantageous for implementing various form factors and designs.
Samsung Display plans to set up a demo zone where visitors can experience the thinness of panels with OCF technology at this year's MWC 2025 exhibition. Lee Joo-hyung, head of Samsung Display's small and medium-sized display division, noted, "We will introduce OCF technology that meets the demand for low power consumption, eco-friendliness, outdoor visibility, and thin, lightweight designs at MWC 2025, and provide direction for next-generation display innovation to customers and consumers."
