Tianma released a folding screen optical fingerprint recognition solution

According to Tianma’s official news, Tianma has overcome difficulties through technological innovation and is the first in the industry to launch an optical fingerprint recognition solution for folding screens.

According to the official introduction, the Tianma R&D team integrated the optical system and the flexible TFT optical fingerprint sensor in the OLED panel through technological innovation to achieve perfect integration with the screen, without the need for additional optical imaging components and achieved an ultra-thin module thickness increment of less than 0.15mm.

According to the official, the OLED panel integrated fingerprint imaging system is used, that is, a layer of light-shielding pinhole array is added to the TFT film layer of the panel to realize high-precision imaging of the fingerprint area above the screen, which can be perfectly adapted to new OLED application technologies such as TPOT, CFOT, and HTD. It is equipped with a new generation of fingerprint-unlocking solutions for the ultra-thin flagship machine.

The flexible TFT optical fingerprint sensor independently developed by Tianma is as thin as less than 0.1mm, which is 80% thinner than the traditional silicon-based optical sensor; and it also has ultra-high resolution above 1000PPI, accurate output ultra-clear For fingerprint images, the exposure time is as low as 0.125s. According to the official, with the recognition algorithm of the whole machine, a zero-pause unlocking experience is realized.

According to the official, Tianma optical fingerprint recognition technology can effectively increase the area of the flexible TFT sensor through advanced manufacturing processes and then realize full-screen fingerprint recognition. Users can unlock it by touching any area of the screen. Compared with traditional silicon-based and glass-based sensors, Tianma’s flexible TFT sensor has better performance in terms of size, thickness, mechanical reliability, etc., and can support full-screen fingerprint recognition, taking a leading position in the industry. In addition, full-screen unlocking does not require a fixed unlocking position, which will improve the burn-in problem caused by the traditional optical fingerprint recognition technology that needs to frequently light up the fixed recognition area of ​​the OLED screen, and prolong the life of the OLED screen.
