In the past, OLED panel was the only standard to install an in-display fingerprint sensor but recently Huawei has installed this display fingerprint on an LCD panel.
At Huawei Developer Conference 2019, Huawei has showcased some new technologies and one of them is the LCD screen with an in-display fingerprint.
Compared to an OLED Panel, LCD panel doesn’t need to be modified for the display fingerprint and only needs to be equipped with optical infrared technology that doesn’t emit light and will increase the fingerprint recognition speed.
Another factor of this new tech is that the company can install in-display fingerprint on the low price segments devices, which already comes with LCD displays.
Currently, Huawei has not announced any plan on launching devices with this new LCD and in-display fingerprint.
