Samsung Unveils World's First OLED Display With Built-In Fingerprint and Blood Pressure Sensing

Samsung Display has unveiled a new generation of OLED panel that it says can recognize fingerprints anywhere on the screen and even check the user's heart rate, blood pressure, and stress levels using multiple simultaneous finger readings.

Samsung's 'Sensor OLED Display' at SID Display Week 2023

Usually, fingerprint sensors in smartphones are attached under the display panel as a separate module and are only sensitive to fingerprint data within a limited portion of the screen. By contrast, Samsung's new "Sensor OLED Display" extends this sensitivity to the entire screen by embedding a light-sensing organic photodiode (OPD) into the panel itself.

The technology currently being shown off at SID Display Week 2023 opens up some exciting possibilities for future smartphones, such as multi-finger authentication (putting four fingers on the display, for example), which could offer several thousand million times stronger security than a single finger.

Another potential feature could be the ability to authenticate individual apps on a phone's Home Screen simply by placing a finger on the app icon to open it, replacing the need for a passcode or facial authentication.

But perhaps the most intriguing claim being made is the ability of the Sensor OLED Display to check cardiovascular health, including blood pressure when two fingers are used.

"To accurately measure a person's blood pressure, it is necessary to measure the blood pressure of both arms," notes Samsung Display's press release. "The Sensor OLED display can simultaneously sense the fingers of both hands, providing more accurate health information than existing wearable devices."

Samsung says the system works because OLED light is reflected differently depending on the contraction and relaxation of the blood vessels inside the finger, and when it returns to the panel, the OPD is able to recognize it and converts it into a blood pressure reading.

Samsung did not provide information on the accuracy rate or speed of its Sensor OLED display, nor did it explain whether the authentication and biometric readings could be taken at the same time, but the company clearly has confidence that the technology is destined for smartphones in the near future.

Could it or something similar one day appear in an iPhone? It's no secret that Apple has been working on a Touch ID system designed to be set under the display since at least 2013, with several patents awarded to the company over the years. Indeed, despite claims that under-screen Touch ID on a future iPhone is unlikely, Apple has, if anything, intensified its research in under-screen fingerprint sensing technology.

Earlier this year, Apple was granted a patent relating to under-screen Touch ID that combines shortwave infrared technology with an optical imaging system that could have multiple functions. Not only does the latest embodiment aim to read the user's fingerprint when it touches the display, it could also determine vein pattern, blood oxygenation, pulse, and the presence of gloves and wetness.

At this point, we can't be certain that Apple will ever put Touch ID under iPhone screens. There also remains a possibility that Apple instead introduces an iPhone with Touch ID built into a physical side button, in line with the latest iPad Air and iPad mini models, although there haven't been any rumors to suggest that Apple plans to follow that route.

Apple's roadmap for under-panel technology, as outlined by DSCC industry consultant Ross Young, suggests we're unlikely to see an under-screen version of Touch ID in an iPhone anytime soon. Apple appears to be more focused on moving Face ID and the front-facing camera under the display, both of which it aims to achieve by 2027.

Android 12 will bring the end of third-party share menus

Apps like Sharedr will no longer be able to replace the default share dialog. What you need to know Third-party apps will not be allowed to replace the Android share menu in Android 12. You will no longer be able to set apps like Sharedr as the default. Google says it never intended to allow third-party apps to replace the official Sharesheet. One of Android 12 's biggest highlights is the new Material You design language, which brings major changes to nearly every key UI component. Android 12 will also introduce a major change to the way users share links and photos, according to a report from XDA Developers . On Android 11 , Google allows third-party apps and OEMs to fully customize the Android Sharesheet, which is the reason why the share dialog differs from one app to another. It is even possible to completely bypass the official Android Sharesheet by setting an app like Sharedr as the default Sharesheet. In addition to providing a more consistent experience, Sharedr

The new Amazon Fire HD 10 is growing into a viable productivity tablet

An already good entertainment device finally gets productive. Amazon has been busy churning out a whole host of new devices and upgrades to existing devices over the past several months. Earlier this year, I reviewed the excellent Echo Buds (2nd Gen) , and even the fantastic Echo Frames (2nd Gen), have since been updated to include options with sunglass and blue light filtering lenses . In early May, we also learned that Amazon was refreshing the Echo Show 5 and Echo Show 8 and that it was even rolling out its first Echo Show for kids . While newer and more novel products like the ones mentioned above often see a faster update cycle, more mature devices like Kindle e-readers and Fire tablets go longer between new versions. In fact, the last update to the Fire HD 10 line was back in 2019, so, understandably, Amazon was ready to reinvigorate its flagship tablet. Not only did it update the specs and colors on the Fire HD 10, but it also gave us a second version in the Fire HD 10 Plu
