The screen is the most indispensable part of a smart phone. Especially after Jobs brought the first touchscreen smart phone to the iPhone, the screen of the mobile phone has become larger and smaller, and the form has also continuously evolved. From the original 16:9 ratio to a screen with a higher percentage of screens, the front of the phone will gradually become the screen for content display.
With the continuous development of full-screen technology, the frontal fingerprint recognition technologies that are popular among people have to be moved to other locations in order to make way for the screen, which also affects the user experience when using the fingerprint function. Full screen and frontal fingerprints Is the identification function really an unsolved puzzle?
At present, there are four types of fingerprint recognition on the market: frontal fingerprint recognition, back fingerprint identification, side fingerprint recognition, and screen fingerprint recognition. In terms of experience, back and side fingerprint recognition must be taken when the phone is used and then operate again. , experience is lacking; and positive fingerprint recognition requires the front of the screen to open holes, and the pursuit of a higher proportion of the screen does not match the current mainstream. In contrast, screen fingerprinting naturally become the best choice in the era of full screen .
As of now, only the vivo X20Plus screenprinting and vivo X21 screenprinting have been truly realized without aperture optical solutions. Vivo has adopted advanced optoelectronic fingerprinting solutions on both products. The principle of operation is when the finger touches the screen. The light from the OLED screen penetrates through the cover plate to illuminate the fingerprint texture. The fingerprint reflects light through the screen and reaches the sensor. Finally, a fingerprint image is formed for identification. Whether it is product stacking, structural design or chip sensitivity, screen thickness, etc. The optical fingerprinting scheme used is the most mature.
In actual experience, the vivo X21UD equipped with an optoelectronic fingerprinting module, as long as the fingerprint finger has been placed on the screen fingerprint image, it will use the photoelectric reflection principle to identify the pressed fingerprint pattern, instantly complete the unlock, pay and other operations; When the fingerprint function is not needed, the fingerprint image will be invisible and will not affect the visual effect.
Thanks to the optical fingerprint recognition module, Vivo's X21UD is more natural and smooth. The interaction is concentrated on the screen and brings more immersive experience. At the same time, the back of the entity fingerprint recognition module is more integrated. For a machine with a full screen In terms of type, the screen fingerprinting scheme can not only ensure that the fingerprint recognition stays on the front but does not occupy any area at the same time. It will increase the screen usage rate to the highest, and at the same time, it will not lose the previous physical prefix fingerprint in the experience. For most full-screen models, screen fingerprinting may be the best solution for both face value and experience.
Of course, the screen fingerprinting solution still needs to overcome the technical difficulties of R&D and mass production. It is also true that only the vivo group can achieve this function, and we look forward to the subsequent emergence of half-screen or full-screen fingerprint identification solutions so that users can enjoy The strongest visual impact can also enjoy the use of better fingerprinting functions, bringing the benefits of technological advancement to the hands of more people.
