JDI showcased world’s first Transparent Glass-based Capacitive Fingerprint Sensor for smartphones and it is likely to start commercial shipments in the current year itself. It is considered to be an alternative to recently launched in-display fingerprint sensor but it does not work like that. It is possibly an upgrade to traditional silicon-based fingerprint scanners.

Traditional fingerprint readers are made up of silicon, hence they were non-transparent. Japan Display Inc. has used the basic touch functionality technology to develop transparent fingerprint sensor. It has been integrated into JDI’s Pixel Eye displays which are used in smartphones and cameras. Latest development is unique because it integrates touch functionality into the glass substrate with Pixel Eye. Most importantly transparent fingerprint sensor works on LCD panels as well instead of OLED panels required on Clear ID sensor developed by Synaptics. The glass substrate easily identifies the area touched by the finger by detecting the changes in capacitance caused due to recesses and ridges of an individual’s fingerprints.
Few days back, Vivo launched first smartphone to house under-display fingerprint sensor dubbed as Vivo X20 Plus UD in collaboration with Synaptics. Smartphone is official now and available to purchase in China at a price of CNY 3,598 (approx Rs.35,999) The in-display reader sits between the glass and OLED display. The transparent fingerprint sensor can be a major challenger to in-display sensors because of high flexibility and its working on traditional LCD panels.
JDI claims that “the advantage of the high transparency of the glass substrate, which silicon-based sensors do not have, combined with a backlight will lead to the expansion of fingerprint sensors in new areas of application.” The also added that newly developed transparent fingerprint sensor will be available in variety of sizes including one with 8.0mm x 8.0mm (0.45-inch) dimensions.
Well, JDI thinks that this new transparent solution will expand the usage of fingerprint sensor into various applications. But, mobile makers have already started ditching this form of biometric methods as Apple introduced Face ID in iPhone X getting rid of Touch ID on its previous flagship iPhones. Samsung’s iris scanner is another attempt to an alternative biometric authentication method. We can expect more smartphones in India without fingerprint sensors in future.
Folding the recent development, it is certain that JDI’s glass-based capacitive fingerprint sensors will be able to replace silicon-based fingerprint sensors that are currently used for smartphone and notebook PC applications and aimed to bring more affordable smartphones with LCD panel displays.
