Confused whether OPPO K9 Pro is equipped with screen fingerprint unlocking function? PHP editor Baicao will reveal the answer to you today. This article will introduce in detail the screen fingerprint function of the OPPO K9 Pro model, covering unlocking speed, usage experience and other aspects, to help you fully understand the fingerprint unlocking experience of this new phone.
What about screen fingerprints
Under-screen fingerprint recognition is currently divided into light-sensitive fingerprint recognition and ultrasonic fingerprint recognition. Its working principle is to use the internal sensor to emit a light/ultrasonic fingerprint signal, and then compare it with the original recorded fingerprint. If the fingerprint is the same, the unlocking can be completed. Among them, the ultrasonic receiver performs processing to obtain the fingerprint information and then compares it with the originally recorded fingerprint. If the fingerprint is the same, the unlocking can be completed. Through this process, under-screen fingerprint recognition can achieve a high degree of security and accuracy.
Under-screen fingerprint scanners can further increase the screen-to-body ratio and promote the true popularity of full-screen displays. In addition, through penetration recognition technology, the recognition process can be completed even under water, and it can be used normally in multiple usage scenarios.
Unlocking operations are mostly similar to the push-type fingerprints we used before, but at present, under-screen fingerprints are still in the development stage, and the unlocking speed and accuracy are still far behind capacitive fingerprints, especially when wet. It is basically impossible to unlock if your hands or fingers are stained.

The Pebble Smartwatch Is What Smartwatches Should Have BeenMay 13, 2025 am 12:12 AMMiss Pebble: A smartwatch in the true sense Before those tiny watch computers tried to implement all the functions of their phones, there was a watch called Pebble. It has a completely different experience from today's smartwatches, and I can't help but hope that the Pebble concept will be more popular. Always on display without compromise What makes Pebble the most successful is its display. Instead of using a high-power, bright OLED screen, it uses an electronic ink screen, the same as the Kindle e-reader. This means the screen is always on, easy to read even in direct sunlight, and it consumes almost no power. I can do it for a few days, or even a week or more without charging. In contrast, the P I currently use
