Philips integrates in its smartphone the innovative fingerprint sensor developed by EgisTec

After a first introduction in the Aurora i966, EgisTec integrates again its fingerprint ET300 in the Philips i999, a smartphone for the Chinese market.
With very simple technical choices concerning the technical detection design and the packaging, EgisTec offers a very competitive sensor in terms of size and manufacturing cost.

Located on the back side of the smartphone, the fingerprint sensor of the Philips i999 has dimensions of 11.6 x 11.6. It is assembled on a square LGA packaging and is protected by metal support.

The sensor has a resolution of 17,920 pixels with a pixel density of 500ppi. It uses a capacitive touch technology to take an image of the fingerprint from the subepidermal layers of the skin.
The sensor die is manufactured with CMOS 0.15µm technology and it is connected by mean of wire bonding to the rigid PCB.

Thanks to its design and manufacturing process, EgisTec device is very smart and cost effective in respect to the competitors.

The report includes comparisons with the latest Huawei’s, Samsung’s and Apple’s fingerprints buttons.
