【Lansheng Technology Information】Recently, at the 2023 SID Display Week event held in the United States, Samsung demonstrated a brand new screen panel called Sensor OLED, which is the world's first OLED panel with built-in fingerprint sensor and heart rate sensor.

There is no significant difference in display performance between the Sensor OLED panel and the traditional OLED panel, but the Sensor OLED panel has a built-in light-sensing OPD (organic photodiode), which makes it no longer necessary to separate the screen under the screen during the production process of mobile phones and other products. Installing the fingerprint sensor not only reduces the space occupation, but also reduces the cost. Samsung says the technology can significantly reduce the complexity of a phone or tablet by integrating biometric and health-tracking sensors.

According to Samsung Display, this light-sensing technology is built into each pixel of the new OLED panel, so it can simultaneously sense fingerprints or heart rate information from multiple fingers. This will allow devices to provide more accurate biometric authentication and measure blood pressure.

It is reported that the display using Sensor OLED can measure the user's heart rate, blood pressure and stress level, just by touching two fingers. Depending on the constriction and relaxation of the blood vessels in the finger, the OLED light is reflected in different ways, and when it returns to the panel, the OPD recognizes it and converts it into health information. A Samsung Display representative said: "The Sensor OLED display can simultaneously sense the fingers of both hands, providing more accurate health information than existing wearable devices."

The emergence of this Sensor OLED panel not only provides users with more convenient and safer biometric identification functions, but also greatly reduces the manufacturing cost and process complexity of manufacturers' products, and can also make future mobile phones or tablets, etc. Products become thinner and lighter. It is understood that Samsung said that in the future, the Sensor OLED panel will be preferentially applied to the Galaxy series of mobile phones and tablets.
