Samsung showcases a variety of paradigm-shifting, next-generation OLED technologies

During the recent SID Display Week event in California, Samsung Display, a subsidiary of Samsung, showcased an array of panel technologies. These included a scrollable OLED display screen, capable of extending from a width of 5 centimeters to a length of 25 centimeters, and the Flex In & Out screen design that is adaptable to both inward and outward folding. Also featured was an OLED screen endowed with a built-in fingerprint recognition and blood pressure measurement function.

The showcased panel technologies have yet to be confirmed for use in commercial products and might serve merely as an external technological demonstration by Samsung. The scrollable OLED display screen, capable of extending from a width of 5 centimeters to a length of 25 centimeters, may become a future design pattern for tablet devices or find applications in a variety of smart display devices. The Flex In & Out screen design, accommodating both inward and outward folding, is expected to be utilized in smartphone products, thereby expanding the possible uses of these devices.

The OLED screen, featuring built-in fingerprint recognition and blood pressure measurement capabilities, might influence future phone design, potentially measuring physiological parameters such as blood pressure and fingerprints. This is primarily achieved through the light-sensing organic photodiode (OPD) that illuminates the vasodilation and vasoconstriction changes within the finger, thereby measuring blood pressure data. It could also further identify users’ fingerprint characteristics, serving as a form of identity recognition.

However, it is still uncertain whether this design will be used in new iPhone models. Some rumors suggest that Apple might reintroduce the Touch ID fingerprint recognition feature to its iPhone line, although this depends on whether the components solution meets their requirements.
