In January 2018, vivo released the world's first mobile phone equipped with screen fingerprints, the X20 Plus screen fingerprint version. It has been more than a year since then, and time has passed quickly. During this period, the development of screen fingerprints has also made a breakthrough. From the earliest slow identification and poor experience, it is now comparable to traditional physical fingerprints.

At present, mobile phones equipped with screen fingerprints have one thing in common - OLED screens, most of which are from Samsung's AMOLED, and this is largely due to technical reasons, but now, the situation will be different. The domestic manufacturer BOE has launched a new LCD panel that can be used with the screen fingerprint module. The reason why previous screen fingerprint phones are AMOLED is that this material is thinner than LCD, but its cost will also be higher, so the screen fingerprint function usually only appears in high-end products.

However, the commercialization of this technology is not fast. According to BOE, this LCD that can match screen fingerprint hardware will be mass produced at the end of this year at the earliest and at the beginning of next year at the latest. Once this technology goes to the public, a large number of low-end computers equipped with screen fingerprint function will appear. At that time, more and more users will use this technology, and it will also leave the "black technology" category. In 2017, when people heard that they can use fingerprint to unlock on the screen, they still felt very strange, Maybe this is the charm of technology.
