Fingerprint (under display, optical)

“Fingerprint (under display, optical)” refers to a biometric authentication method used in smartphones. In this case, it indicates that the fingerprint sensor is located beneath the display (under display) and uses optical technology for scanning. This setup allows users to unlock their devices by placing their finger on a designated area of the screen, which then uses light to capture and authenticate the fingerprint pattern. It’s a convenient and secure way to access your device and protect sensitive information.
