The consumer 3D sensing module market is expected to reach $8.1B in 2025, up from $2B in 2019, according to the “3D Imaging & Sensing 2020” report from Yole Développement. In this context, Samsung has entered the Time of Flight (ToF) sensing market by introducing its first near infra-red (NIR) camera found in the Meizu 17 pro’s ToF module.

This full reverse costing study has been conducted to provide insights into technology data, the manufacturing cost and selling price of the rear ToF module in the Meizu 17 pro.

The 3D sensing module is packaged in one metal enclosure and includes a new Back-side Illumination (BSI) NIR CMOS Image Sensor (CIS) from Samsung. The sensor features 7 µm pixels and a resolution of 0.3 Mpixels. The ToF uses a vertical cavity surface emitting laser (VCSEL) coming from Lumentum.

A wafer level chip scale packaging (WLCSP) driver integrated circuit from PhotonIC generates the pulse and drives the VCSEL’s power and beam shape.

Along with the complete technical analysis of the 3D depth sensing system, this report analyses the cost and estimates the price for the system. It also includes a technical and cost comparison with the rear 3D sensing system in the Galaxy Note 10+ and the iPad pro.
