"With more than 120 designs in several flagships on the market, Goodix this year offers a new version of the fingerprint sensor. It’s called the ultra-thin in-display optical fingerprint sensor, and it uses a micro lens design instead of optical lenses. The sensor is located on the front of the device, directly under the glass display and the organic light emitting diode (OLED) material.

 

This report focusses on analyzing the optical sensor and its integration under the display. The sensor is manufactured from a Front-Side Illumination CMOS Image Sensor (FSI-CIS), with an on-chip Near InfraRed (NIR) filter, collimator and Micro Lens Array (MLA). 

The component also includes features to provide a small gap between the CIS and the OLED material.

 

Since the last version of the device, Goodix made several changes at the optical level but also at the integrated circuit (IC) level. Indeed, the sensor doesn’t require any additional circuits besides the sensor IC. Power management and signal processing rely on the main board chipset."
