It’s no secret that sub-screen fingerprint scanners are gaining popularity more and more rapidly, replacing conventional ones even in the mid-budget segment of smartphones. At the beginning of this year, the Chinese manufacturer Fortsense announced the start of production of fingerprint scanners for more affordable LCD displays (TN, IPS and others), and already now their competitors, Tianma, have presented the world’s first full-screen TFP (TED Finger Print) solution. Yes, the Chinese really managed to make the entire surface of the screen a single scanner, which removes the need to aim a certain area on the display with your finger.
The world’s first full-screen fingerprint reader for LCD screens is ready
Another important development is the possibility of increased integration. For example, touching the icon of a fingerprint-protected application will result in a one-time reading of the finger pattern and identification of the owner, eliminating the need to enter a password or unnecessary finger movements. According to representatives of Tianma, the technology is now ready for mass production. And the company has begun sending samples of devices into the hands of well-known brands.
TCL to launch an LCD on-screen fingerprint technology this year
According to previous reports from China, TCL has developed a single-point LCD on-screen fingerprint technology. The report claims that the full-screen single-point on-screen fingerprint technology will be official this year. As for the full-screen multi-point on-screen fingerprint technology, it will have to wait until 2021. According to the company, it spent two years trying to deliver the on-screen fingerprint technology.
The R&D team successfully solved the development of BLU films and the improvement of TPM brightness. The company developed an on-screen fingerprint solution for LCD panels, which can clearly identify the fingerprint of the LCD panel. It was also able to improve the infrared sensor recognition accuracy. The company did this through continuous reformation and attempts of the LCD backlight board.
This is not the first time that we are getting reports of a Chinese manufacturer with an LCD on-screen fingerprint technology. Last year, there were reports that Xiaomi will release a smartphone with this technology this year. We do not know if that is still going to happen. Furthermore, there were also reports of Huawei having an LCD display with a fingerprint sensor. However, we are yet to see the preponderance of this technology. We will have to keep our fingers crossed and watch how far TCL goes with this technology.
