LG's new Fingerprint Reader Sits Under a Smartphone Screen

Fingerprint Readers – Abundant in Smartphone Designs

Fingerprint readers seem to be abundant in the designs of smartphone with queries like, whether they should include them or where to accommodate them. While some of the manufacturers have opted in adding readers in the button on the front or raised area on the back of the devices, LG Innotek has come up with a latest idea of putting it under the screen of the phone.

The LG associate had announced that it had created a new fingerprint sensor which has been inserted into a small 0.01 inch space cut in the underside of smartphone glass cover enabling the designers of the device to include fingerprint reader without committed button, pads or other exposed components. LG has stated that the fingerprint recognition rates on the under-glass module are comparable to button-kind sensor and could reduce any kind of smartphone malfunctions, together with bonus of enabling phone to be waterproof as well as scratch-resistant or only designed to appear sleeker.

No announcement has been made yet by the company whether it would be utilising this new module in any of the upcoming phone. However a spokesperson of LG had informed the Korea Times that the company is in talks with some smartphone manufacturers in order to commercialize the new sensors, within the year.

LG’s Fingerprint Sensor under the Display

Few years ago, Apple had begun pioneering smartphone fingerprint sensors in its smartphone with the iPhone 5s and since then various manufacturers had introduced fingerprint sensors on their smartphones. Presently, LG is pioneering and is touting its new fingerprint sensor which tends to sit under the display which means that when one tends to place their finger on the cover glass of the display, the under glass fingerprint sensor module seems to automatically identify your fingerprint.

As announced by Jongseok Park, CEO of LG Innotek, the under glass fingerprint sensor module will eliminate dedicated buttons, pad or other elements for fingerprint recognition and will also help in making the smartphone more water resistant by decreasing the number of openings. This could also be the cause of slimmer devices in the near future.

 LG Innotek has mentioned that it has cut 0.01-inch slot towards the back of the cover display glass and has set up a fingerprint sensor in it with `supreme precision and combination technology’.

Fingerprint Sensor Module – False Acceptance Rate – FAR

It has also been stated that the fingerprint sensor module tends to have a false acceptance rate – FAR of 0.002%. Besides this, LG also informs that the adherence side of the glass as well as the fingerprint sensor is 0.0098-inch thick, with the capability of resisting the impact of a 130 gram steel ball dropped from 7.9-inch. Changhwan Kim, Head of Research and Development Centre LG has mentioned that they are concentrating on all resources to the development of the differentiated technology based on the creation of customer value and will continue to provide convenient, safe and pleasant user experience by launching innovative product.

LG has not disclosed when precisely we would start seeing this technology in smartphone or the other devices. In December last year, the company had been tipped to supply Oled displays for their forthcoming iPhone models.
