OLED optical technology and a breakthrough full-screen mobile phone will become a reality

February 04, 2016

Recently, a research institute called Fraunhofer abroad showed a new screen technology that minimizes finger-level finger biological data.

        Samsung Galaxy S8 officially released before the outside world had rumors that Samsung will use the screen in the Galaxy S8 under the fingerprint recognition technology. But in the end, Samsung did not really turn rumors into reality. In order to achieve up to 83% of the screen share, Samsung was forced to have the fingerprint identification button transferred to the back of the fuselage. And now, the latest invention of the Fraunhofer Institute means that we are a step closer to achieving true screen fingerprint recognition technology.
Before we saw Apple's acquisition of micro-LED screen technology company LuxVue news, compared with the latter, Fraunhofer technology is the difference in the OLED screen integrated high-precision fingerprint scanner. Researchers began to study the technology as early as 2012, but to the latest results have reached the accuracy of 1600dpi, compared with the previous three times a full increase.
In essence, this unique new technology uses OLED pixels as light sources, illuminates the fingers, and then detects and analyzes the reflected light. Bernd Richter, the company's department manager, said the optical scanner was very thin and built into the screen with an exclusive ultra-thin packaging technology. And the distance between the finger and the image sensor is minimized, so that the fingerprint data can be captured more accurately. Therefore, this technology does not require additional imaging optics.
The most impressive is, though thin, but this high resolution can determine the minimum to the level of the pores, which means that this OLED screen recognition technology is very safe. To know that optical fingerprint scanning is the most primitive fingerprint recognition, because it has been scanned for optical images, so it is not difficult to implement. The Fraunhofer Institute's new technology, which formally addresses this major drawback.
Although Fraunhofer's new technology is going to be used for a long time to be commercially available, it shows at least the possibilities and vision of the next smartphone for fingerprint capture technology.
