Tianma and TCL CSOT announce multi-point in-display fingerprint biometrics for LCD screens
Tianma Microelectronics has announced a multi-point in-display biometric fingerprint recognition sensor for LCD screens to unlock smartphones by touching different points on the display, writes Gizmochina.
Tianma claims the technology is proprietary, developed with its own team. The image processing element is integrated in a TFT display layer for concurrent touch, display and fingerprint sensing. The company allegedly used optical path design to make the module 50 percent slimmer. Until Tianma’s release, under-display fingerprint sensors were only available for OLED panels.
TCL’s China Star Optoelectronics Technology has also developed in-display fingerprint technology for LCD screens that allegedly operates on 92 percent of the display screen, allowing multiple touchpoints anywhere on the surface.
The latest sensor developments are not yet available on the market, but Gizmochina says mass manufacturing of the biometric technology is expected to start this year.
