Samsung unveils a 12.4-inch rollable OLED panel

During the recent Display Week trade show held in Los Angeles, Samsung unveiled an impressive 12.4-inch rollable OLED panel, which has the potential to revolutionize the display industry. While rollable display concepts have been introduced before, Samsung’s innovation stands out from the competition due to its significant advancements. This groundbreaking display is not only the largest rollable panel seen to date but also rolls up into a compact scroll, adding to its appeal and practicality.

At the recent Display Week trade show in Los Angeles, Samsung showcased a remarkable 12.4-inch rollable OLED panel that introduces significant advancements to the display industry. One standout feature of this innovation is its impressive scalability, ranging from 49mm to 254.4mm. This represents a remarkable 5x scalability, surpassing the current sliding screens that can only expand up to 3x their original size. Samsung Display accomplished this feat by implementing an O-shaped axis design, reminiscent of a scroll, which they aptly named Rollable Flex. Notably, the panel has the capability to be completely rolled up, adding to its versatility and user-friendly design.

Samsung showcased the Rollable Flex, a fully rollable OLED panel, and the Flex In & Out OLED panel at the Display Week trade show. The Flex In & Out panel allows bending in both directions, unlike current technology used in devices like the Galaxy Flip4 and Fold4.

Last, but not least, the Korean tech giant also introduced the world’s first OLED panel with an integrated fingerprint reader and heart rate sensor. Current implementations rely on a small sensor area while Samsung’s solution allows you to unlock the handset with a touch of a finger anywhere on the screen surface. It has embedded the light-sensing organic photodiode (OPD) into the panel itself. The tech can also read blood pressure, heart rate and stress by monitoring the blood vessels’ contraction and relaxation.
