Samsung’s new OLED display panels have integrated fingerprint and health sensors, potentially paving the way for the return of Touch ID in future iPhone models.

The Sensor OLED Display can measure a person’s heart rate, blood pressure, and stress level with a touch of two fingers on the screen. In contrast to the conventional approach of incorporating fingerprint sensors as separate modules beneath the panel, Samsung Display has integrated the light-sensing organic photodiode (OPD) directly within the panel structure.

The reflection of OLED light undergoes distinct variations based on the expansion and contraction of blood vessels within the finger. As the light returns to the panel, the integrated OPD detects these changes, converting them into valuable health data.

“To accurately measure a person’s blood pressure, it is necessary to measure the blood pressure of both arms,” the company. “The Sensor OLED display can simultaneously sense the fingers
