Smartphones with screens that take up almost all available space, i.e. bezel-less mobiles, have one serious problem. It is of course a fingerprint reader that is placed by the back of many manufacturers. That is why a lot of people are waiting for smartphones that will be equipped with a reader integrated with the OLED display. Chinese Vivo has already prepared such a model. However, Samsung remains for now with a traditional solution. At least this will be the case with the Galaxy Note 9. The new technology may appear in next year’s Galaxy S10.
Rumours about the lack of a fingerprint reader integrated with the OLED screen in Galaxy Note 9 appeared already last month. However, now Ming-Chi Kuo, an analyst from KGI Securities, revised his last year predictions about the implementation of new technology by Samsung. A half a year ago, everyone hoped that the fingerprint reader under the OLED screen will appear in the Galaxy Note 8, and the capacitive sensor located on the back of the Galaxy S8/S8+ is only a temporary solution. Especially that Synaptics has already presented the first fingerprint reader that can be integrated with OLED displays (Clear ID FS9500 system), and Vivo has used it in a commercial Vivo X20 Plus UD smartphone. In contrast, the conceptual Vivo APEX, which will go on sale later this year, has a fingerprint reader operating on the half of the screen surface.
The technology of readers integrated with the OLED screen is still unfinished
Vivo is well aware that they use a solution that still needs to be refined. One of the problems with the Clear ID FS9500 sensor is that it stops working when some type of protection glass is used. That is why Vivo decided to sell glasses verified by manufacturer. Another problem is the deterioration of the effectiveness of the new reader in adverse weather conditions. JDI is working on a transparent fingerprint reader that can be put on the display, but the dubious durability of the solution remains a problem. Also, the Qualcomm Sense ID ultrasonic technology is problematic, because it does not work with OLED screens. That is why people specializing in the analysis of the consumer electronics market believe that Samsung has for the time being relinquished the application of new solutions in the area of biometric security. However, Ming-Chi Kuo believes that Samsung Electronics will soon refine the fingerprint reader, which will be integrated with the OLED display in next year’s Galaxy S10.
