Chinese panel manufacturer Tianma Microelectronics today announced the release of TED Finger Print (TFP), the world's first multi-point, in-screen fingerprint solution for LCD screens.
The solution is a fingerprint image capture device embedded in a TFT display substrate, which for the first time integrates the three functions of touch, display and fingerprint recognition into one.
It covers the entire display with an optical path and sensor, and is equipped with a sensor based on a glass substrate that has no size limitation.
Tianma said the TFP in-screen multipoint fingerprint solution has three core benefits.
Highly integrated. This technology is the first to achieve touch, display and fingerprint recognition in one.
It breaks through the limitation that optical fingerprint inside LCD screen is difficult to match the normal cover thickness, making it more competitive and mass-producible.
As the optical modulation unit is integrated into the display, the thickness of the display is reduced by more than 50% compared to the external collimated optical path design, making the end product design thinner and lighter.
Full-screen fingerprint multipoint recognition. It supports fingerprint multi-point identification of the entire screen at any display area, which can be applied to blind unlock of the whole screen, APP encryption and unlock, and custom fingerprint control.
High screen-to-body ratio. The fingerprint recognition function is built into the display, which can effectively increase the screen-to-body ratio of the end product and provide users with a more extreme visual experience.
Under-screen fingerprint identification technology is a technology that completes the fingerprint identification and unlocking process through the bottom of the screen glass, including capacitive, optical and ultrasonic categories.
However, due to technical and cost reasons, most of the products currently equipped with this technology can only achieve single-tap fingerprint recognition in a fixed area.
Tianma's solution integrates a fingerprint image grabber into the display, providing a larger recognition area than off-screen fingerprint products.
Currently, Tianma's technology is ready for mass production and samples are being sent to partners worldwide.
