The technology is still in its infancy, but several Chinese manufacturers already offer smartphones with in-display fingerprint sensors. Xiaomi is now showing the prototype of a new sensor that could solve the most serious problems of current models.

Last year, the first smartphones with fingerprint sensors integrated into the display came onto the market. So far, only Chinese manufacturers rely on the technology, in addition to Vivo, Oppo and OnePlus also Huawei. Xiaomi is still holding back, except for a special issue of Mi 8, the company always installed the fingerprint sensor on the back of his smartphone - even with the current top model Mi Mix 3. Apparently, Xiaomi is not satisfied with the currently available optical sensors, because as the CEO and Co-founder Lin Bin now points out in a Weibo post, are currently being tested new ways for the implementation.

This includes first enlarging the area on which the fingerprint is scanned. All current in-display fingerprint sensors require the user to place a finger on a predetermined position of the display. The scan area is about the size of conventional sensors, but that's the problem: you always have to look where your finger needs to be placed. This disadvantage would be eliminated if the area were larger. According to Xiaomi, the sensor currently under test has a size of 5 x 2.5 centimeters.

In addition, Xiaomi wants to have accelerated the technology. The registration of a fingerprint should already be completed after a single prolonged contact - with current sensors, this is a rather tedious process that can extend over several minutes. In a short video in the Weibo Post, Lin Bin shows that the prototype is also superior in speed when compared to current in-display fingerprint sensors and unlocks a smartphone as you would expect after just a brief touch.

Other manufacturers want to improve the technology

Latest smartphones like that The Huawei Mate 20 Pro, the OnePlus 6T or the Honor Magic 2 have optical fingerprint sensors installed in the screen. Besides Xiaomi, Oppo and Vivo are also working on ways to increase the reliability of the technology and to accommodate larger sensors in their smartphones. By contrast, in the upcoming top smartphone Galaxy S10, Samsung will probably be using an ultrasound sensor for the first time: it works on a potentially significantly larger surface and also recognizes dry or sweaty fingers.
