It is already possible to integrate an optical fingerprint sensor under the LCD screen, increasing the chances of bringing this technology to low-cost phones
Fingerprint sensor integrated under the screen is no longer a strange technology for most smartphone users today. However, the biggest drawback of this technology is that it can only be integrated with expensive OLED screens, which makes the price of the product much more expensive, and often only appears on high-end smartphone models. above.
To overcome this problem, 3M, a multidisciplinary company and particularly well-known in the fields of electronic materials, medical products and electronic circuits, has successfully developed a method that allows sensor integration. Optical fingerprint in LCD panel, this technology can be used on cheaper product lines, reach more users.
Fingerprint sensor under the screenThe secret lies in proprietary technology Near Infrared Transmission System (NITS) (3M). NITS uses an advanced, ultra-thin 3M optical screen film that allows for easy 'implanting' of optical fingerprint reader sensors on the back of the LCD screen.
In the past, conventional LCD screen films would block the visibility of the optical sensor, making them unable to read your fingerprints. Meanwhile, the new 3M screen film can block up to 97% of the visible light in the infrared spectrum, allowing the infrared optical sensor to read fingerprints quickly without encountering any Any obstacle.
In other words, using a new film material that significantly improves the transmission of infrared rays cannot go through the screen, so the sensor can verify fingerprints. This technology can be applied directly in tablets, laptops and other LCD devices to provide advanced full-screen biometric security.
Hopefully in practical use, this solution can provide fingerprint scanning capabilities fast and accurate not inferior to the integrated sensor under the OLED screen.
