Japan Display’s new technology will allow fingerprint sensors embedded within the display

We have heard under-display fingerprint sensor tech that Vivo and Synaptics have been working on, but in-glass is a first.

After the recently announced Vivo smartphone with Synaptics’ under-display fingerprint sensor, Japan Display has pushed the game up a notch and announced an in-glass fingerprint sensor technology. The company plans to start commercial shipments of the technology within its 2018 fiscal year. Japan Display said in its announcement that it has developed “a transparent glass-based capacitive fingerprint sensor by applying the company’s capacitive multi-touch technology used in its other liquid crystal displays (LCDs)”.

The transparent glass-based capacitive fingerprint sensor will use the touch technology that they already use for touchscreen displays. The sensor is integrated into the glass via a transparent glass substrate and it is able to detect the touch. Consequently it reads and identifies the ridges and recesses of a fingerprint without the need for a silicon-based sensor.  “JDI will expand the lineup to include larger or smaller sizes as well as this 8mm x 8mm sensor.”

Application-wise, the transparent glass-based fingerprint sensor has a wide scope. Besides the obvious integration into smartphones, laptops and PCs, with the rise in use of biometrics in smart cars and other Internet of Things (IoT) products, that opens a who lot of opportunities.

Transparent fingerprint sensors should improve the degrees of design freedom to enable such sensors to be installed in nearly every device to make security enhancement much easier.
