Apple may be struggling with iPhone 8’s rumored optical fingerprint sensing functionality, according to Pacific Crest analysts in a research note issued to customers on Monday.
According to Ming-Chi Kuo, an Apple analyst of KGI Securities in January, a new fingerprint-reading solution in the form of an optical sensor could be adopted on iPhone 8. This eliminates the need for physical contact with a users’ finger.
In a conversation with suppliers, the Pacific Crest analysts have wondered if Apple could address the technical problems regarding optical fingerprint sensing. It remains unclear if production for iPhone 8’s optical fingerprint module has started. While the current-generation Touch ID system does not work properly through the display’s cover glass, the only solution now lies in optical fingerprint verification with no need of physical contact with a user’s finger.
The Touch ID sensor is said to be located behind the screen to make space for a larger display. A bespoke flexible OLED display design is a requirement for an in-screen fingerprint reader based on an optical sensor because it helps prevent potential signal interference.
Supposing that the firm cannot offer optical fingerprint sensing functionality for iPhone 8 in time, they may have to relocate the current Touch ID sensor to the rear of the smartphone as suggested, which may not meet users’expectations. However, it is possible that the company may use an advanced facial recognition system based on a 3D sensor.
Cowen and Company’s Timothy Arcuri predict that the smartphone would use a laser sensor near the Face Time camera that may be used for facial and gesture recognition features.
